The Complete Side Hustle Tax Guide for 2026

My first year side hustling, I made $18K from DoorDash. I figured I would owe income tax on it — fine, I expected that. What I did not expect was the second tax bill: 15.3% self-employment tax on top of my regular income tax. Nobody mentioned that part. Not the YouTube videos I watched, not the Reddit threads I read, not the friend who told me to "just keep receipts." The IRS hit me with a $1,800 underpayment penalty on top of a tax bill that was $6K more than I had planned for. That is how I learned how side hustle taxes actually work.

I am not a CPA. I am a guy who got burned and did a lot of homework. This guide is everything I wish someone had handed me before that first 1099 showed up — how self-employment tax works, when the IRS expects you to pay, which deductions actually matter, and the mistakes that cost me real money. If you have a W-2 job and you are making money on the side, this is for you.

Do You Have to Pay Taxes on Side Hustle Income?

Short answer: yes. Every dollar you earn is taxable unless a specific section of the tax code says otherwise — and there is no section that exempts side hustle money. The IRS treats it as self-employment income, which means you owe both income tax and self-employment tax on it.

I hear the same thing constantly from people just starting out: "I didn't get a 1099, so I don't have to report it, right?" I thought something similar my first year — figured if DoorDash didn't send me a form, the IRS wouldn't know. That is wrong, and the confusion comes from mixing up two completely different numbers:

• $2,000 — the threshold where a company that paid you is required to send a 1099-NEC form for 2026. OBBBA raised this from $600 effective January 1, 2026. That is their obligation, not yours. If a client pays you $1,500, they no longer have to file a 1099. But you still owe taxes on that $1,500.
• $400 — the number that actually matters to you. If your net self-employment income (revenue minus business expenses) hits $400 for the year, you must file a tax return and pay self-employment tax. No 1099 required for that to kick in.

One thing that tripped me up early on — the $400 threshold applies to net income, not gross. If you earned $2,000 driving for a rideshare but had $1,700 in expenses (gas, maintenance, depreciation), your net self-employment income is $300. No SE tax owed. But that $300 still counts toward your gross income for income tax purposes, and you still have to report it.

Once your net self-employment income from all side hustles combined crosses $400, you must file Schedule SE (Self-Employment Tax) and Schedule C (Profit or Loss From Business) for each separate business activity. I file two Schedule C forms — one for freelance work, one for my FBA side. That part is not as bad as it sounds once you have your numbers organized.

Understanding Self-Employment Tax

This is the tax that blindsided me. When you work a W-2 job, you see Social Security and Medicare deductions on your pay stub — 7.65% coming out of each check. What most people never think about is that your employer is quietly paying the other 7.65% on your behalf. When you are self-employed, there is no employer. You pay both halves. I thought my side hustle money was just... extra. Nobody told me I was also my own employer.

How Self-Employment Tax Breaks Down

Two components here, and knowing the split matters:

Social Security tax: 12.4% on net earnings up to the Social Security wage base ($184,500 for 2026). If you also have W-2 wages, those count toward this cap — so your side hustle earnings only get taxed on the Social Security portion up to the point where your combined income hits $184,500.

Medicare tax: 2.9% on all net earnings, no cap. Plus an additional 0.9% surtax on earnings above $200,000 for single filers ($250,000 married filing jointly).

Combined rate: 15.3% on the first $184,500 of combined earnings, then 2.9% on everything above that (plus the surtax if applicable). That 15.3% on top of income tax is the thing that makes every new side hustler's jaw drop — and it is the single biggest reason people end up owing thousands more than they planned.

The Silver Lining

The IRS does soften the blow slightly. You can deduct 50% of your self-employment tax when calculating your adjusted gross income. This is called the "employer-equivalent portion" — it mirrors the fact that a W-2 employer's share of payroll taxes is not taxable income for the employee. You get this deduction regardless of whether you itemize or take the standard deduction. It is an above-the-line deduction on Form 1040, which means it reduces your AGI and therefore your income tax.

My Actual Numbers

I will use my own first-year numbers because round hypotheticals never felt real to me when I was trying to learn this. I had $18K in DoorDash income, $4,200 in expenses, $13,800 net — that is what I owed SE tax on.

Step 1: The IRS multiplies net self-employment income by 92.35% (this adjustment accounts for the employer-equivalent portion). $13,800 x 0.9235 = $12,744.

Step 2: Calculate SE tax. $12,744 x 15.3% = $1,949.83.

Step 3: Deductible portion. $1,949.83 / 2 = $974.92.

So on $13,800 of net side hustle income, I owed roughly $1,950 in self-employment tax alone — before income tax. My AGI increased by $12,825 ($13,800 minus $975), not the full $13,800. The income tax on that depends on your marginal bracket, which brings us to the next section.

How Side Hustle Income Is Taxed

Self-employment tax is only half the hit. Your side hustle profit is also subject to regular federal income tax — and the part most people misunderstand is that it stacks on top of your W-2 income. It does not get its own fresh set of brackets. It sits right on top of whatever your day job already put you at.

Reported on Schedule C

All self-employment income and expenses go on Schedule C (Profit or Loss From Business), filed as part of your 1040. You file a separate Schedule C for each distinct business activity — I file one for freelance content work and a separate one for Amazon FBA, because the IRS views those as two different businesses. Your Schedule C net profit flows to two places:

1. Schedule SE, where it is used to calculate self-employment tax.
2. Form 1040, where it gets added to your other income (W-2 wages, investment income, etc.) to determine your total taxable income and income tax bracket.

Combined with W-2 Income for Tax Brackets

The U.S. uses a progressive tax system — your income is taxed at increasingly higher rates as it rises through the brackets. Your side hustle profit stacks on top of your W-2 wages, so it gets taxed at your marginal rate, not starting from zero. This is the part that stung when I was still working logistics and side hustling on weekends. My W-2 had me in the 12% bracket. My DoorDash income pushed part of my earnings into the 22% bracket. I did not realize that would happen until I saw the final number on my return.

What that looks like for a single filer in 2026:

Income Source	Amount	Tax Bracket (2026)	Approximate Federal Income Tax
W-2 salary	$55,000	Spans 10%, 12%, 22%	~$6,308
Standard deduction	-$16,000	--	--
Taxable W-2 income	$39,000	Top bracket: 12%	~$4,478
Side hustle net profit	+$15,000	12% and 22%	~$2,556
SE tax deduction (50%)	-$1,060	--	--
New taxable income	$52,940	Top bracket: 22%	~$7,000

The W-2 salary alone sits in the 12% bracket. Adding $15,000 in side hustle income pushes part of that into the 22% bracket — but only the portion that crosses the threshold gets taxed at 22%. That is how marginal rates work, and it is one of the most commonly misunderstood things in personal finance.

On top of the ~$2,556 in income tax on the side hustle income, add about $2,120 in self-employment tax ($15,000 x 0.9235 x 15.3%). Total tax on $15,000 of side hustle earnings: roughly $4,676, or about 31%. That is why I tell people to set aside 30% — it is not being conservative, it is being realistic.

State Tax Considerations

I live in Texas, so I do not owe state income tax on any of this — which is one less thing to worry about. But most states do tax self-employment income. Rates range from 0% (Texas, Florida, Washington, a few others) to over 13% in California for high earners. If you live in a state with income tax, your side hustle income increases your state tax bill just like it increases your federal bill. Some states also require their own separate estimated tax payments on top of federal estimated payments — check your state's department of revenue for specifics. We have detailed state-specific guides for California, New York, Texas, Florida, and Illinois.

Quarterly Estimated Tax Payments

This is the section I wish I had read before my first year of side hustling — because this is where my $1,800 penalty came from. When you have a W-2 job, your employer withholds taxes from every paycheck and sends them to the IRS. Nobody does that for your side hustle income. The IRS expects you to send it yourself, four times a year. I did not know that. I found out in April, when it was too late.

Why You Need to Pay Quarterly

The U.S. tax system is pay-as-you-go. The IRS does not want to wait until April 15 to get taxes on income you earned the previous January. If you wait until filing to pay everything at once, they will charge an underpayment penalty — even if you pay every cent you owe. The penalty is essentially interest on the money you should have been sending all year. Mine was $1,800. That is not a rounding error.

Who Must Pay Estimated Taxes

If you expect to owe $1,000 or more in federal taxes for the year after subtracting withholding and credits, you need to make quarterly payments. For most people with real side hustle income, this threshold is easy to hit — $5,000 or more in net profit and you are almost certainly in quarterly territory.

There is one workaround I have seen people use: increase your W-2 withholding through Form W-4 so your day job covers the extra tax. This can work if your side hustle income is modest and you do not want to deal with quarterly payments. But if you are making $15K+ on the side, I would set up the quarterly payments — it forces you to actually track what you owe.

Quarterly Due Dates for 2026

Quarter	Income Earned During	Payment Due Date
Q1	January 1 - March 31	April 15, 2026
Q2	April 1 - May 31	June 15, 2026
Q3	June 1 - August 31	September 15, 2026
Q4	September 1 - December 31	January 15, 2027

Look at the dates closely — the quarters are not evenly divided. Q2 covers only two months (April and May), while Q3 covers three months (June through August). That is an IRS quirk that messes people up. I put all four dates as recurring events in my phone calendar with a one-week advance reminder. Do that now.

How to Calculate Your Estimated Payments

The Form 1040-ES worksheet walks you through it, but the basic math is straightforward:

1. Estimate your total income for the year (W-2 wages plus side hustle net profit).
2. Calculate your expected total tax liability (income tax plus self-employment tax).
3. Subtract whatever your W-2 employer is withholding.
4. Divide the remainder by 4. That is your quarterly payment.

If your side hustle income is lumpy — say you make most of your money in Q4 — you can use the annualized installment method (Form 2210, Schedule AI) to base each quarterly payment on what you actually earned that quarter. More paperwork, but it keeps you from overpaying early in the year when business is slow.

The Safe Harbor Rule

This is the rule that would have saved me $1,800 if I had known about it. You will not owe an underpayment penalty if your total payments (withholding plus estimated payments) cover at least one of these:

• 90% of your current year's tax liability, or
• 100% of your prior year's tax liability (110% if your AGI exceeded $150,000 in the prior year).

The prior-year method is the easy one because you already have the number — it is the total tax on last year's return. Divide by 4, subtract your expected quarterly W-2 withholding, and pay the difference as estimated tax each quarter. That is what I do now, and I have not had a penalty since that first year.

Essential Tax Deductions for Side Hustlers

Deductions reduce your taxable income, which lowers both your income tax and your self-employment tax. Every legitimate business expense you do not deduct is money you are handing to the IRS for free. I learned this the hard way — my second year, I signed up for Keeper Tax and it flagged $2,100 in deductions I had completely missed in year one. I had been leaving money on the table for two years because I did not know what counted.

For a full list with dollar amounts, read our detailed guide: Side Hustle Tax Deductions You're Missing. Below are the big ones.

Home Office Deduction

If you use a dedicated space in your home regularly and exclusively for your side hustle, you can deduct a portion of your housing costs. The key word is "exclusively" — a desk in the corner of your living room does not count if anyone else uses that space for anything. A spare bedroom that is only your office does count.

Two methods to calculate it:

• Simplified method: $5 per square foot of your office, up to 300 square feet. Maximum deduction: $1,500. Dead simple, no receipts needed for housing costs.
• Actual expense method: Measure your office, divide by your home's total square footage, and apply that percentage to rent or mortgage interest, utilities, insurance, repairs, and depreciation. More work, but usually a bigger deduction.

Vehicle Expenses

I drove 11,400 miles for DoorDash my first year and deducted exactly zero of them — because I did not track a single mile. I tried to reconstruct 3 months of mileage from my Google Maps history, gave up around February, and lost what would have been a $8,265 deduction at 72.5 cents per mile. Never again. Now I use a mileage tracking app from day one of every tax year.

You have two options for vehicle deductions:

Method	How It Works	Best For
Standard mileage rate	72.5 cents per business mile (2026). Multiply total business miles by this rate.	Most side hustlers. Simpler tracking, usually the better deal unless you drive an expensive vehicle.
Actual expense method	Track all vehicle costs (gas, insurance, maintenance, repairs, depreciation) and deduct the business-use percentage.	People with high vehicle costs or a car used almost entirely for business.

You cannot deduct commuting miles — driving from home to a regular workplace. But if your home is your principal place of business, drives from home to meet clients or to a secondary work location are deductible.

Internet and Phone

If you use your personal phone and internet for business, you can deduct the business-use percentage. The problem is figuring out what that percentage actually is — trying to calculate that 40% of my personal phone bill was business use felt like guesswork, and guesswork makes me nervous at tax time. So I got a separate prepaid line on Lyca Mobile for $10/month. Now I deduct 100% of that line because it is used solely for business calls and texts. Clean, simple, no math.

Same principle for internet: if you estimate 30% of your usage is business-related, deduct 30% of the monthly bill. If you have a separate connection used only for work, deduct all of it.

Software and Tools

Any software or online tool you pay for and use in your business is deductible — accounting software, design tools, project management apps, website hosting, domain names, cloud storage, industry-specific subscriptions. I deduct QuickBooks Self-Employed, my Canva Pro subscription, and my domain registrations. These are small amounts individually, but they add up. My software deductions alone totaled $847 last year.

Health Insurance Premiums

If you are not eligible for health insurance through an employer plan (yours or a spouse's), you can deduct 100% of the premiums you pay for yourself, your spouse, and your dependents. This is an above-the-line deduction — you get it regardless of whether you itemize. It reduces income tax but not self-employment tax.

Retirement Contributions

Self-employment income unlocks retirement account options that also work as tax deductions. I opened a SEP IRA in my third year of side hustling and immediately regretted not doing it sooner — the tax savings are real.

• SEP IRA: Contribute up to 25% of net self-employment income (after the 50% SE tax deduction), up to $72,000 for 2026. Contributions are deductible.
• Solo 401(k): Both employee contributions (up to $24,500, plus $8,000 catch-up if 50+) and employer contributions (up to 25% of net SE income). Total limit $72,000 ($80,000 with catch-up). Most flexibility, but more setup.
• Traditional IRA: Up to $7,000 ($8,000 if 50+), though deductibility may be limited if you or a spouse are covered by a workplace plan.

Professional Development and Education

Courses, books, conferences, workshops, and certifications that maintain or improve skills in your current business — all deductible. Education that qualifies you for an entirely new profession generally is not. I deducted a $299 SEO course last year because it directly improved my freelance content business. That is the kind of thing people forget to track.

Record Keeping and Expense Tracking

My first year, my "recordkeeping system" was a Google Sheets file I updated once a month when I remembered. By December it was three months behind and missing half my expenses. I spent two weekends in March scrolling through bank statements at midnight trying to remember which Starbucks visits were client meetings. That is not a system — that is damage control.

If the IRS ever questions a deduction, the burden of proof is on you. No receipt, no deduction. No mileage log, no mileage deduction. The stakes are real.

What Records to Keep and for How Long

• 3 years from the filing date — the standard retention period.
• 6 years if you underreported income by more than 25% of gross income.
• 7 years if you claimed a deduction for bad debts or worthless securities.
• Indefinitely if you did not file a return or filed a fraudulent one.

What to keep: bank statements, receipts, invoices, contracts, mileage logs, home office measurements, and anything that supports a number on your return. I keep all of mine in a dedicated Google Drive folder organized by year, and QuickBooks handles the categorization.

Separate Business Bank Account

This was the single most useful change I made in year two. I opened a Relay account and set up three sub-accounts: one for tax savings, one for operating expenses, one for owner's pay. Every time money comes in, I split it immediately — 30% goes to the tax account and I do not touch it. That money belongs to the IRS. The remaining 70% gets split between operating expenses and what I can actually spend.

You do not need a fancy business checking account. A separate personal account used exclusively for business transactions works fine. The point is separation — clean records, easy bookkeeping, and a paper trail that will not make an auditor's eyes glaze over. See our guide to the best business bank accounts for side hustlers for options with no fees.

Mileage Tracking

If you use your vehicle for business, you need a contemporaneous mileage log — meaning you record it at or near the time of the trip, not in March from memory. I learned this the hard way. I tried to reconstruct 3 months of mileage from my Google Maps timeline, and even that only captured about 60% of my actual business drives. Now I use an app that runs in the background and logs every trip automatically.

Your log needs four things for each trip: date, destination, business purpose, and miles driven. Apps like MileIQ, Everlance, and Stride handle all of this through GPS and satisfy the IRS requirement for contemporaneous records.

Receipt Management

Paper receipts fade. I had a stack of gas station receipts from my DoorDash days that were completely blank by tax time — the thermal paper had faded to nothing. For a full breakdown of what documentation you actually need to keep, see our guide on what receipts to keep for your side hustle. Take a photo of every business receipt the day you get it. Most accounting apps have built-in receipt scanning that extracts the data and attaches the image to the transaction. At minimum, dump photos into a dedicated folder on your phone.

Do You Need an LLC for Your Side Hustle?

I formed my LLC in Texas in 2022. It cost $300, took 20 minutes online, and I immediately felt like I was playing business dress-up. But here is the thing — from a tax perspective, it changed almost nothing. From a liability perspective, it gave me something I sleep better having.

LLC vs. Sole Proprietor for Taxes

If you run a side hustle without forming a business entity, you are a sole proprietor by default. A single-member LLC is what the IRS calls a "disregarded entity" — they treat it exactly the same as a sole proprietorship. Same Schedule C, same self-employment tax, same deductions. Forming an LLC does not change your tax bill by a single dollar. I did not form mine for tax reasons. I formed it because I wanted the liability wall.

Liability Protection

An LLC creates a legal separation between your personal assets and your business. If someone sues your business or it takes on debts it cannot pay, your personal assets — home, car, savings — are generally protected. As a sole proprietor, that wall does not exist.

How much this matters depends on what you do. Freelance writing? The liability risk is pretty low. Personal training, home repair, childcare, selling physical products? That is where liability protection starts to actually matter. I sell products through Amazon FBA, which means there is a non-zero chance someone could have an issue with something I sold. The LLC gives me a layer of separation I did not have before.

When an LLC Makes Sense

It is not a universal recommendation. Here is when I think it is worth the filing fee:

• Your side hustle carries meaningful liability risk — physical services, products, or consulting where something could go wrong.
• You want a more professional business identity for landing clients.
• You plan to bring on a partner or investor down the road.
• Your state's filing fees are reasonable. They range from $50 to over $500 depending on the state, and some charge annual fees on top. Texas was $300 with no annual fee — pretty painless.

S-Corp Election for Higher Earners

If your side hustle consistently generates $40,000+ in net profit, an S-Corp election starts to look interesting. Your LLC can elect S-Corp tax treatment by filing Form 2553 with the IRS. The advantage: you split your income into a "reasonable salary" (subject to payroll taxes) and distributions (not subject to self-employment tax). That split can save thousands per year.

The downsides are real though — you must run payroll for yourself, file a separate S-Corp return (Form 1120-S), and pay yourself a salary the IRS considers "reasonable." The admin costs and complexity make it impractical for most small side hustles. I am not there yet. I know how this works for single-member setups, but multi-member S-Corp structures? That is CPA territory, not something I would try to figure out from blog posts.

For a deeper dive, read our complete guide to whether you need an LLC for your side hustle.

1099 Forms Explained

January rolls around and your mailbox starts filling up with 1099s — or it does not, and you think you are off the hook. Neither reaction is the right one. These forms are informational — they tell the IRS what you got paid. Copies go to you and to them. What you are actually looking at:

1099-NEC (Non-Employee Compensation)

This is the most common one for freelancers and contractors. Any business that paid you $2,000 or more for services during the year (the 2026 federal threshold raised from $600 by OBBBA, effective January 1, 2026) must send you a 1099-NEC by January 31. "Services" means work you did as a non-employee — it does not cover products you sold them.

Important: the total on your 1099-NEC forms will probably be less than your actual income, because clients who paid you under $2,000 do not have to send one. You still owe taxes on all of it. I had four clients my first freelance year — two sent 1099s, two did not. All four payments went on my Schedule C.

1099-K (Payment Card and Third-Party Network Transactions)

This one reports payments through platforms — PayPal, Venmo (business profile), Stripe, Square, Etsy, eBay, Amazon. For 2026, OBBBA restored the pre-ARPA reporting threshold: $20,000 in gross payments AND more than 200 transactions. If you fall below either side of that AND, the platform is not required to issue you a 1099-K — but you still owe taxes on every dollar you earned.

One thing that confused me at first: the 1099-K reports gross transaction amounts before fees and refunds. So if you sold $3,000 on Amazon but Amazon took $450 in fees, your 1099-K says $3,000. You deduct the $450 as a business expense on Schedule C — do not just report $2,550, or the numbers will not match what the IRS has on file.

What If You Do Not Receive a 1099?

No 1099 does not mean no tax obligation. A client pays you $400 for a project — below the $2,000 threshold, so no 1099 required from them. You still report that $400 on Schedule C. Same for cash payments, payments from individuals (who generally do not issue 1099s), and small payments from multiple clients that individually fall below $2,000.

Report everything. The IRS has more data sources than you think, and their matching algorithms are better than they were even five years ago. It is not worth the risk of omitting $400 when the penalty for underreporting is worse than the tax you would have owed.

For a thorough comparison of how 1099 and W-2 income are treated differently, read our 1099 vs W-2 Complete Tax Guide.

Common Side Hustle Tax Mistakes

I have made most of these myself. That is not a flex — it is the reason this section exists. Most side hustlers overpay or get hit with penalties not because the rules are complicated, but because they make avoidable mistakes early on and do not realize it until April.

1. Not Setting Aside Money for Taxes

This was my original sin. DoorDash deposits hit my checking account and I spent them — because they felt like bonus money. They are not bonus money. Roughly 25-30% of every dollar belongs to the IRS (more if your state has income tax). I owed $6K more than I expected that first year because I treated side hustle income like it was all mine.

The fix: every time side hustle money comes in, immediately move 25-30% to a separate account you do not touch. I use my Relay tax sub-account for this. The money goes in and stays there until a quarterly payment is due. If you are in a high-tax state, bump that to 30-35%.

2. Missing Quarterly Estimated Tax Payments

Setting money aside is step one. Actually sending it to the IRS on time is step two — and it is the step where my $1,800 penalty came from. The IRS charges interest on each quarter you should have paid and did not. These are not catastrophic penalties, but they are entirely avoidable. Four calendar reminders. That is all it takes.

3. The Reconstruction Trap

Trying to reconstruct a year of business expenses in March is a guaranteed way to miss deductions. I did it — scrolling through bank statements at midnight trying to figure out which Starbucks visits were client meetings. You will forget things. You will give up on the small stuff. And the small stuff adds up. I switched from a spreadsheet to QuickBooks Self-Employed halfway through my second year. Took me about 2 hours to set up, saved me roughly 10 hours at tax time. Track expenses as they happen, whatever tool you use.

4. Mixing Personal and Business Finances

Running everything through your personal checking account makes it brutal to identify business transactions at tax time. It also increases your audit risk because the paper trail is messy. A separate bank account takes 15 minutes to open and saves hours of sorting later. Read our guide on how to separate personal and business finances for practical steps.

5. Not Knowing Which Deductions You Qualify For

I did not claim the home office deduction for two years because I assumed it would trigger an audit. It does not — not if you actually qualify. I also had no idea I could deduct health insurance premiums, retirement contributions, or a portion of my internet bill. Keeper Tax finding that $2,100 in missed deductions was my wake-up call. Every dollar you do not deduct is a dollar the IRS taxes unnecessarily.

Read our complete guide to side hustle tax deductions. Keep the list visible. Ask your tax professional specifically about deductions you might be missing.

Tools and Resources

I spent my first year managing taxes with a spreadsheet and a shoebox of fading receipts. It did not go well. What I actually use now, plus some options I have tested or researched for people at different stages:

Accounting Software

I have used QuickBooks Self-Employed for three years. It connects to my bank account, auto-categorizes most transactions, tracks mileage, and estimates my quarterly tax payments. It costs $15-25/month depending on the plan, and for me it has been worth every dollar. That said, it is not the only option:

Software	Price	Best For
QuickBooks Self-Employed	$15-25/month	Side hustlers who want automated expense tracking and quarterly tax estimates. Full review.
FreshBooks	From $17/month	Service-based freelancers who invoice clients regularly. Strong invoicing, clean interface.
Wave	Free	Side hustlers with simple needs who want invoicing and expense tracking without paying for it. The free tier is genuinely useful.

For a deeper comparison, read our best accounting software for freelancers review.

Tax Filing

I file with TurboTax Self-Employed. It costs roughly $120 plus $50 per state — not cheap. If I were starting over and did not have a complex multi-schedule situation, I would seriously consider FreeTaxUSA, which handles Schedule C for free on federal returns ($14.99 for state). Other options:

• IRS Free File: If your AGI is $84,000 or less, you can file federal for free through partner software, including Schedule C. Check irs.gov/freefile.
• FreeTaxUSA: Free federal filing including Schedule C. State is $14.99. Best value for most side hustlers.
• TurboTax Self-Employed: ~$120 plus state. The most guided experience, but you are paying for hand-holding more than capability.

Free Tax Preparation

• VITA (Volunteer Income Tax Assistance): Free tax prep for people earning $64,000 or less, people with disabilities, and limited English speakers. IRS-certified volunteers who can handle Schedule C. Find a location at irs.gov.
• TCE (Tax Counseling for the Elderly): Free tax prep focused on retirement issues. Available to all ages despite the name.

IRS Resources

• IRS Direct Pay: Make estimated payments directly from your bank account, no fees. This is what I use every quarter. Available at irs.gov/directpay.
• EFTPS: Schedule payments in advance — useful if you want to set up recurring quarterly payments so you do not forget.
• IRS Publication 535: The official guide to business expenses. Dry as dust, but it is the authoritative source if you need to settle a question about whether something is deductible.
