Upwork Taxes: Fees, Forms, and What You Owe
Upwork is a payment platform, not an employer. Nothing is withheld, you are self-employed, and the service fee it deducts from every contract is a business expense you claim rather than money that simply disappeared.
A freelancer billing $55,000 on Upwork, paying $5,500 in platform fees and $4,500 in other business costs, has $45,000 of profit and owes $8,579.50 in federal tax — about 19.1%.
How it's calculated
Upwork processes client payments, which makes it a third-party settlement organisation, so US freelancers who clear the threshold receive a Form 1099-K. For 2026 that threshold is over $20,000 in payments and more than 200 transactions. Plenty of successful freelancers work on a handful of large contracts and never reach 200 transactions, so no form arrives — and the income is fully reportable regardless.
The important mechanical point is that a 1099-K reports gross payments. It reflects what clients paid into the platform, before Upwork's service fee came out. Your withdrawals are net. Report the gross figure as income on Schedule C and deduct the fees as a business expense: you land on the same profit, and your return reconciles with what Upwork told the IRS. Silently reporting only your withdrawals leaves a mismatch that is easy to query and hard to explain later.
Upwork's fee is only the first deduction. Freelancers on the platform typically have several more that gig drivers do not: software subscriptions, professional insurance, a home office if a space is used regularly and exclusively for work, hardware, courses and books relevant to the work, accounting fees, and the business-use share of phone and internet. Connects — the credits Upwork charges to submit proposals — are a business cost too, and the ones spent on proposals that went nowhere are just as deductible as the ones that won work.
At this income level the picture is different from a part-time gig driver's. With $45,000 of profit, the standard deduction no longer absorbs everything: self-employment tax is $6,358.30 and federal income tax adds $2,221.20, for $8,579.50 and an effective 19.1% of profit. That is well above the 14.1% a low-earning driver pays, and it is why the same set-aside advice cannot serve both.
Upwork income also has no withholding at any point in the chain, so the whole amount is paid through quarterly estimates on Form 1040-ES. Freelancers with lumpy contract income should set aside the percentage from each withdrawal as it arrives rather than reserving a quarterly lump sum — our guide to budgeting with irregular income covers the due dates and the safe-harbour rule, and the freelance rate calculator shows what to charge so the take-home survives all of it.
A worked example
A freelance developer bills $55,000 through Upwork across the year. Upwork's service fee takes $5,500, and another $4,500 covers software subscriptions, a laptop, professional insurance, accounting fees, and Connects spent on proposals.
Net profit is $45,000. Self-employment tax applies to 92.35% of that: $6,358.30.
Half of it is deducted above the line, then the $16,100 standard deduction and the QBI deduction come off, leaving $2,221.20 of federal income tax. The total federal bill is $8,579.50 — 19.1% of profit, or $2,144.87 due each quarter.
Common mistakes to avoid
- Assuming no 1099 means no tax. For 2026 a payer only files a 1099-NEC at $2,000 (up from $600) and a payment app only files a 1099-K above $20,000 and 200 transactions. Those are the payer's filing rules. Your own obligation starts at $400 of net self-employment earnings, and the IRS says to report gig income whether or not a form arrives.
- Paying nothing until April. Self-employment income has no withholding, so the IRS expects quarterly estimated payments. Waiting until you file can add an underpayment penalty on top of a bill you already were not expecting.
- Not tracking miles or expenses from day one. You are taxed on profit, not on what the platform paid you — but only for the expenses you can actually document. A mileage log reconstructed in April from memory is the single most commonly disallowed deduction.
- Reporting only your Upwork withdrawals as income. The 1099-K reports gross client payments before fees; report the gross and deduct the fee, or your return will not reconcile with what Upwork filed.
- Forgetting to deduct Connects and unsuccessful proposal costs. They are business expenses whether or not the proposal won the contract.
- Assuming no 1099-K means no reporting. Large-contract freelancers often clear the dollar threshold but never reach 200 transactions, so no form arrives — the income is still fully taxable.
Frequently asked questions
Does Upwork take out taxes?
No. Upwork processes client payments but withholds nothing for US freelancers — no income tax, no Social Security, no Medicare. Its service fee is a platform charge, not tax. You owe self-employment tax of 15.3% on 92.35% of your profit plus federal income tax, and you pay both yourself through quarterly estimated payments.
Does Upwork send a 1099?
US freelancers who exceed the 1099-K threshold receive one — over $20,000 in payments and more than 200 transactions for 2026. Because both conditions apply, freelancers with a few large contracts often clear the dollar figure without hitting 200 transactions and receive nothing. The income remains fully reportable: the IRS requires it whether or not a form is issued.
Can I deduct Upwork's service fee?
Yes, and you should. If a 1099-K was issued it reports gross client payments before the fee, so deducting it is what brings your reported income down to what you actually received. Report the gross as income on Schedule C and the fee as a business expense. Connects spent on proposals are deductible too, including on proposals that did not win the work.
What else can Upwork freelancers write off?
Software and subscriptions, hardware, professional and liability insurance, a home office used regularly and exclusively for work, the business-use share of phone and internet, accounting and legal fees, courses and books relevant to your services, and business travel. Each deduction reduces self-employment tax and income tax together, which for a freelancer in the 12% bracket makes a deductible dollar worth about 26 cents.
How much should Upwork freelancers set aside for taxes?
Around 20% of profit at $45,000, rising as income does — the effective federal rate at that level is 19.1%, not the 30% commonly quoted. Add your state's income tax on top, and set aside more if you also have W-2 wages, since freelance profit stacks on your salary at your top marginal rate. Move the percentage out of each withdrawal as it clears rather than saving in quarterly lumps.
