About Upwork and 1099 Income
Upwork is the world's largest freelancing marketplace, connecting businesses with freelancers in tech, writing, design, marketing, and more. US-based Upwork freelancers are self-employed independent contractors.
Upwork freelancers often have complex income — multiple clients, varying rates, and the Upwork fee tier creates different net income per client. Consider using accounting software like Wave or QuickBooks Self-Employed to automatically categorize Upwork income and fees by client.
What Tax Form Does Upwork Send?
Upwork issues 1099-K (for freelancers earning over $5,000 via Upwork Payments). As an independent contractor, you are responsible for reporting this income on Schedule C (Profit or Loss from Business) attached to your federal Form 1040. You are also responsible for paying self-employment tax (15.3%) on your net earnings.
Top Tax Deductions for Upwork Workers
Reducing your taxable income through legitimate deductions is one of the most effective ways to lower your tax bill:
- Upwork service fees (5–20% of earnings depending on client relationship lifetime)
- Software subscriptions and tools used for client work
- Professional subscriptions and industry memberships
- Home office deduction
- Computer hardware (Section 179 or depreciation)
- Internet service (business portion)
- Education and certification costs
- Qualified Business Income (QBI) deduction — up to 20% of net business income for eligible freelancers
- Health insurance premiums if you're self-employed with no other employer coverage
- Retirement contributions (SEP-IRA contributions up to $69,000 or Solo 401k)
Quarterly Estimated Tax Payments
As a Upwork independent contractor, no taxes are withheld from your earnings. If you expect to owe more than $1,000 in federal taxes for the year, you must make quarterly estimated payments to the IRS using Form 1040-ES. The 2026 payment deadlines are April 15, June 16, September 15, and January 15, 2027. Use the calculator above to estimate your exact quarterly amount.
