About 79 million American adults have now earned money with AI, according to a nationally representative survey this summer. They write for clients with ChatGPT, design with Midjourney, build small automations, sell templates and ebooks, post AI-assisted videos, or get paid to train AI models on platforms such as Handshake and Outlier.
Almost none of them had a cent of tax taken out of that money. And under rules that took effect this year, many of them will not receive a single tax form for it.
That combination produces the same moment every spring: someone who earned a few thousand dollars on the side discovers they owe more than they expected, with a deadline attached. The questions people type into Google are always the same. Do I have to pay taxes on a side hustle? Do I have to report it if I didn't get a 1099? How much should I set aside?
Here are the plain answers, the numbers for two typical people, and a five-minute system that avoids the April surprise.
This is general information about US federal rules, not tax advice. If your situation is unusual, for example you are on a student visa or live outside the US, check with a tax professional.
The short answer
| Question | Answer |
|---|---|
| Is side income from AI work taxable? | Yes, all of it, whether or not you get a tax form |
| Is tax taken out automatically? | Usually no. Clients, marketplaces and platforms pay you gross |
| What extra tax applies? | Self-employment tax of 15.3% once your net earnings reach $400 in a year |
| How much should you set aside? | Roughly 25% to 30% of profit, plus state tax where it applies |
| Do you need a form to report it? | No. You report the income even if no 1099 arrives |
| When do you pay? | At tax time, or in quarterly estimated payments if you will owe $1,000 or more |
What counts as AI side income
People earn from AI in very different ways, but for tax purposes almost all of it lands in the same place: self-employment income you report yourself.
| How you earn | Typical example | How it is usually treated |
| Freelance client work | AI-assisted writing, design, coding, automations for clients | Self-employment income |
| Selling through marketplaces | Gigs on Fiverr or Upwork, templates on Etsy, ebooks on Amazon KDP | Self-employment income; platform fees are deductible |
| Creator payouts | YouTube, TikTok or newsletter earnings from AI-assisted content | Self-employment income once it is regular |
| AI training platforms | Rating and writing tasks on Handshake AI, Outlier, DataAnnotation | Paid as an independent contractor; Handshake says all its AI fellows are 1099 contractors |
| One-off or occasional sales | Selling a few AI images or prompts | Still taxable; may be treated as hobby income (see below) |
The common thread is that you are paid gross. An employer would withhold income tax and pay half of your Social Security and Medicare. A client or platform does neither. You do both yourself.
If you are unsure whether you are an employee or a contractor on a particular platform, look at the paperwork you signed. A W-9 means you are almost certainly being paid as a contractor. A W-4 means you are an employee and tax is being withheld.
What changed in 2026: fewer forms, the same tax
Two federal reporting thresholds changed under last year's tax law, and they are behind much of the current confusion.
| Form | Who sends it | Old threshold | Threshold for 2026 |
| 1099-NEC | a client or platform that pays you directly | $600 | $2,000 a year from one payer, indexed for inflation from 2027 |
| 1099-K | payment processors and marketplaces such as PayPal | planned to fall to $600 | $20,000 and 200 transactions, both required |
In practice, if three clients each paid you $1,500 this year, none of them has to send you a 1099-NEC. If you sold digital products through a marketplace and stayed under $20,000, you probably will not receive a 1099-K. Some states still require forms at $600, so you may get some anyway.
The thing that did not change is the tax. These thresholds only decide whether a payer has to file a form. They are not a tax-free allowance.
| What people assume | What is actually true |
| "I didn't get a 1099, so I don't owe anything." | You owe tax on all income, form or no form. |
| "It was under $600, so it doesn't count." | That number, now $2,000, is a reporting rule for payers, not an exemption. |
| "PayPal didn't send a 1099-K, so nobody knows." | You are still required to report it, and platforms keep records. |
| "I only do it part-time." | Self-employment tax applies from $400 of net earnings a year. |
Hobby or business?
If you earn now and then, with no real intention of making a profit, the income can count as hobby income. It is still taxable, but it is not subject to self-employment tax, and you generally cannot deduct your costs against it.
Most people earning from AI regularly, with clients, a shop, a channel or a platform account, are treated as running a small business. That means self-employment tax applies, and in exchange you can deduct genuine business costs. If you are pursuing it seriously and want it to make money, business treatment is usually both the correct and the better answer.
What you will actually owe: two people, worked through
Here are two common cases, assuming no business expenses, so you can see the full effect.
Case 1: $1,500 of side income. Below the new 1099-NEC threshold, so possibly no tax form at all.
| Line | 12% bracket | 22% bracket |
| Self-employment tax | about $212 | about $212 |
| Federal income tax on the rest | about $134 | about $245 |
| Total federal tax | about $346 (23%) | about $457 (30%) |
Case 2: $6,000 of side income.
| Line | 12% bracket | 22% bracket |
| Self-employment tax (15.3% on 92.35% of net earnings) | about $848 | about $848 |
| Federal income tax, after deducting half the SE tax and the 20% qualified business income deduction | about $535 | about $981 |
| Total federal tax | about $1,383 (23%) | about $1,829 (30%) |
That is where the 25% to 30% rule of thumb comes from. State income tax comes on top in most states.
The line people miss is self-employment tax. It is your Social Security and Medicare contribution, the part an employer would normally split with you, and it is owed even if your income is low enough that you pay little or no income tax. On just $1,500 of side income it is still around $212.
What you can deduct
You pay tax on profit, not on everything you are paid. For AI side work, the usual legitimate deductions are:
- AI subscriptions and software you use for the paid work, or the business-use share of them. For a sense of what people typically spend, see what people actually pay for AI.
- Platform and marketplace fees, such as the cut Fiverr, Upwork, Etsy or a payment processor takes. If a 1099-K reports your gross sales, you report the gross and deduct the fees.
- Equipment bought mainly for the work: a second monitor, a microphone, a better webcam.
- A share of your internet and phone bills, in proportion to business use.
- A home office, only if a space is used regularly and exclusively for the work.
Deductions reduce both income tax and self-employment tax, so a $40-a-month AI subscription you genuinely use for client work saves more than people expect. Keep receipts and a note of the business-use percentage.
Quarterly estimated taxes, or the easier route
Because nothing is withheld, the IRS expects people who will owe $1,000 or more to pay during the year in four estimated payments. The last payment for 2026 income is due 15 January 2027.
If you also have a regular job, there is a simpler option: hand your employer a new W-4 asking for extra withholding. The tax on your side income then comes out of your salary automatically, and you never have to remember a quarterly deadline.
There are also safe-harbour rules. In general, if your withholding and estimated payments cover at least 100% of last year's total tax (110% at higher incomes), you avoid the underpayment penalty even if you owe more when you file. For someone in their first year of real side income, that rule often prevents a penalty.
If you live outside the US
The principle is the same almost everywhere, and the details are not. US clients and platforms typically ask non-US people for a W-8BEN instead of a W-9 and do not withhold US tax on work performed abroad. That does not make the income tax-free: in most countries it is self-employment or freelance income declared locally, often with social contributions on top. Check your own country's rules for side income and keep every platform's earnings statement.
If you are in the US on a student visa, check with your school's international office before taking paid side work, because whether you were permitted to do it can matter as much as the tax.
A five-minute system that prevents the April shock
- Open a separate savings account and move 25% to 30% of every payment into it the day it arrives.
- Download your earnings history from every client, marketplace and platform at year end, even if no form arrives.
- Keep one folder for receipts: subscriptions, equipment, fees, the internet share.
- Choose your payment route now: more W-4 withholding at a day job, or estimated payments with the next one due 15 January 2027.
- If you earned more than a few thousand, spend an hour with a tax preparer or the self-employment version of reputable tax software. It usually pays for itself in deductions.
Where this fits
The tax side is the same however you earn from AI, which is part of why it catches so many people out. Half of active AI side hustlers make under $500 a month, which I set out in what 79 million Americans actually earn with AI, and small amounts are exactly where people assume tax does not apply. It does.
If you are deciding how to earn in the first place, the nine ways people actually make money with AI covers the options, and once it becomes regular client work, the complete guide to AI freelancing and how to price your work are the next steps. Price with the 25% to 30% in mind, because that money was never yours to spend.
The honest take
None of this is complicated once someone says it plainly. The trouble is that nobody does at the moment it matters. Clients pay you the full amount, platforms send no form below thresholds most people have never heard of, and self-employment tax only becomes visible in April.
The fix is a habit, not expertise: put a quarter of every payment aside the day it arrives, keep your records, and decide how you will pay before the deadline rather than after. Do that, and your AI side income stays what it should be, a genuinely useful extra few thousand dollars, rather than a bill you cannot pay.
So, before your next payment lands: where is 25% of it going?
Frequently asked questions
Do I have to pay taxes on side hustle income?
Yes. All side hustle income is taxable, whether it comes from clients, marketplaces, creator payouts or AI training platforms, and whether or not you receive a tax form. If your net self-employment earnings reach $400 in the year, you also owe self-employment tax of 15.3%.
Do I have to report side income if I didn't get a 1099?
Yes. A 1099 is a reporting obligation for the payer, not a condition for you owing tax. From 2026, payers only have to send a 1099-NEC at $2,000 or more, so many people with real side income will not receive one.
How much should I set aside for taxes from a side hustle?
About 25% to 30% of your profit for federal tax, depending on your bracket, plus state income tax where it applies. On $6,000 of side income the federal total is roughly $1,400 in the 12% bracket and $1,800 in the 22% bracket.
What is the 1099-NEC threshold for 2026?
$2,000 per payer for the year, up from $600, for payments made after 31 December 2025. It will be adjusted for inflation from 2027.
What is the 1099-K threshold for 2026?
$20,000 in payments and 200 transactions in the year, and both conditions must be met.
Do I pay self-employment tax on a small side hustle?
Yes, once your net self-employment earnings reach $400 in the year. On $1,500 of side income it is roughly $212, even if you owe little income tax.
Are Handshake AI, Outlier or DataAnnotation earnings taxed differently?
No. They are paid to most workers as independent contractor income, with nothing withheld, and taxed exactly like any other self-employment income described here.
