Yes, Prolific earnings are taxable in the US, and you often owe tax on them even though Prolific never sends a 1099. Once your Prolific profit is about $433, you owe self-employment tax. If you also have a job, your Prolific pay gets income tax too, even in small amounts.
I’ve made £574.30 and $45.18 on Prolific since 2023, from 513 paid studies. I file my own taxes with TaxAct. I’ve gotten 1099s from Outlier and Clickworker, but never one for Prolific. Here’s how Prolific taxes work.

Do You Have to Pay Taxes on Prolific?
Yes, once you earn enough. Prolific says participants are independent contractors, not employees. So your Prolific pay is self-employment income, and nothing is taken out for taxes.
That can bring two taxes:
- Self-employment tax: You usually owe it when your net earnings from self-employment are $400 or more. Net earnings are 92.35% of your profit, so the line is about $433 of profit. The rate is 15.3%: 12.4% for Social Security and 2.9% for Medicare.
- Income tax: Only on income above your standard deduction. For 2026, that’s $16,100 if you’re single, $32,200 for married couples filing jointly and $24,150 for heads of household.
Here’s what that means:
- Prolific is your only income and your profit is under about $433: you owe nothing.
- Prolific is your only income and your profit is over $433: you owe self-employment tax, a little over 14% of your profit.
- You also have a job: your Prolific pay gets income tax, plus self-employment tax once your gig profit passes $433.
The $433 line counts all your self-employment profit together, not just Prolific.
Does Prolific Send a 1099?
No. Prolific is a UK company and doesn’t send 1099s. You cash out to PayPal, so your Prolific pay can count toward PayPal’s Form 1099-K instead.
You likely won’t get one. PayPal only has to send a 1099-K when you get more than $20,000 in more than 200 payments in a year. A few states set the bar lower: over $600 in Maryland, Massachusetts, Vermont and Virginia, and over $1,000 in 4 or more payments in Illinois. A 1099-K also counts every business payment to your PayPal, not just Prolific.
No 1099 doesn’t mean no tax. The IRS says gig income has to be reported even if you don’t get a 1099-K, 1099-MISC or W-2.
Prolific Pays in Pounds, but Your Taxes Are in Dollars
About 94% of my Prolific pay came in British pounds. The IRS says you must report the amounts on your US tax return in US dollars, using the exchange rate from when you got paid.
You can also use a posted rate, as long as you use it the same way all year. The IRS publishes yearly average exchange rates and accepts any posted rate used consistently. For 2025, the average was £0.759 per dollar, so £1 was about $1.32.
Converting in PayPal costs a fee, so the dollars that land in your account can be a bit less than your pounds were worth. Here’s how I convert pounds to dollars in PayPal.
Prolific Taxes: How to Report Your Earnings
- Find your total. Your Submissions page shows your total earnings, and you can download your full submission history there. Bonuses that researchers pay later don’t always show up in the download, so check your cash-outs too.
- Convert your pounds to dollars using one of the rates above.
- Report it as self-employment income on Schedule C. Your profit is what’s left after expenses.
- Figure self-employment tax on Schedule SE if your net earnings are $400 or more. You get to deduct half of it.
I file with TaxAct. You add your self-employment income, and it fills in Schedule C and Schedule SE for you. Keep your yearly total and the exchange rate you used in case you need them later.
How Much Tax Will You Owe on Prolific?
Here’s my own example. If all my Prolific earnings, £574.30 and $45.18, had come in one year, that’s about $802 at the IRS’s 2025 average rate. The Prolific tax calculator shows:
- No other income: about $113, all self-employment tax.
- With a $40,000 W-2 job in California: about $215. That’s $72 federal income tax, $113 self-employment tax and $30 California tax.
Your other income changes the answer more than anything else.
Do You Need to Make Quarterly Tax Payments on Prolific?
Probably not. The IRS expects estimated tax payments if you’ll owe $1,000 or more when you file. With no other income, you’d need about $7,000 of Prolific profit to owe that much in self-employment tax. With a job, you get there sooner, but you can ask your employer to withhold more on a new W-4 instead.
My Verdict: Do You Owe Taxes on Prolific?
If Prolific is your only income and you made under about $433, no. Past that, or if you have a job, yes. Prolific won’t send you a 1099, and PayPal probably won’t either, so it’s on you to add up your earnings, convert your pounds and report it.

FAQ
Does Prolific take out taxes?
No. Prolific treats you as an independent contractor, so nothing is withheld.
Do I have to report Prolific income under $600?
Yes. There’s no minimum for reporting income. The $600 you may have heard about was the line for companies to send a 1099, and it rose to $2,000 for 2026.
Will PayPal send me a 1099-K for Prolific?
Only if you get more than $20,000 in more than 200 payments in a year, or less in Maryland, Massachusetts, Vermont, Virginia and Illinois.
Is Prolific income self-employment income?
Yes. It goes on Schedule C, with self-employment tax once your profit is about $433 or more.
Can I deduct expenses from my Prolific income?
Yes, if they’re for your Prolific work, like the work share of your internet. They lower your profit on Schedule C.

In most states, yes, once your total income is high enough. Nine states have no income tax on wages: Alaska, Florida, Nevada, New Hampshire, South Dakota, Tennessee, Texas, Washington and Wyoming.
