How much to set aside for quarterly taxes

There is no single magic percentage for every freelancer. Your effective rate depends on net profit, deductions, and bracket — but most solo 1099 earners land somewhere between 25% and 35% of net income for federal tax alone, with higher earners toward the top of that range.

Use effective rate, not bracket

Saying "I'm in the 22% bracket" ignores SE tax and the fact that lower dollars are taxed at 10% and 12%. The number that matters for set-aside is total tax ÷ net income — your effective rate. Add a cushion for state tax if you live in a state that has one.

When the IRS wants four payments

If you expect to owe $1,000 or more after withholding and credits, you generally need to make estimated tax payments. Due dates are April 15, June 15, September 15, and January 15 (following year). Missing a date triggers interest on the shortfall — not always a huge bill, but it adds up.

Practical habit

Transfer a fixed slice from every paid invoice into a separate account. Re-run your numbers mid-year when income shifts. The quarterly tax calculator splits your annual estimate across the four IRS due dates so you know what each payment should be.
