Quarterly tax
Quarterly Estimated Tax on $200K 1099 Income
The IRS penalty for underpayment is 8% APR (2026). On $200K freelance income the penalty alone can hit $1,500. Here is the math.
The short answer
On $200K 1099 income (single, no other deductions), your 2026 federal tax bill is approximately $42K + $28K self-employment tax = $70K total. You must pay this in 4 quarterly installments of about $17,500 (April 15, June 16, September 15, January 15). Skip a quarter and you owe penalty + interest. Use safe harbor: pay either 90% of this year’s tax OR 110% of last year’s tax.

Bottom line
Set aside 35% of every freelance check into a separate “tax” HYSA. Pay quarterly via IRS Direct Pay. Use the safe-harbor rule (110% of prior year) to avoid all penalties even if income jumps. Track everything in a separate business checking account from Day 1.
