Upwork's fees decrease as you earn more with each client:
Example: $25,000 Upwork earnings with one long-term client

Best for people with regular jobs who freelance on Upwork for extra income
Combining W-2 job and Upwork income
Side hustlers face unique challenges because your day job withholds taxes assuming that's your only income. Upwork earnings create additional tax liability that you must plan for.
Tax impact example: $55,000 W-2 + $12,000 Upwork
Assuming you're single and earn $55,000 from your W-2 job plus $12,000 gross on Upwork (net $10,200 after ~15% fees):
Additional taxes from Upwork:
Your W-2 withholding covers the $55,000 salary but not the Upwork income. You have three options:
1. Increase W-4 withholding: Add ~$307/month extra withholding at your day job
2. Make quarterly payments: $921 per quarter to the IRS
3. Pay when filing: Risk underpayment penalties if you owe $1,000+
Managing cash flow as a side hustler
Upwork pays weekly, making it easier to set aside tax money:
Deduction strategy for side hustlers
Focus on Upwork-specific deductions that clearly relate to your freelance work:
Key takeaway: Side hustlers earning $8,000+ net on Upwork typically need quarterly payments or increased W-4 withholding to avoid penalties.
