The Washington side of each payment
Washington has no personal income tax for 2026, so there is no state estimated payment to make. Everything in the schedule above goes to the IRS.
That does not reduce the federal side: self-employment tax and federal income tax are owed in full, which is why the $50,000 example still needs $2,190 a quarter.
What each quarter costs at three income levels in Washington
A single filer taking the standard deduction, at three levels of net profit. The federal column moves with the self-employment tax and the federal brackets; the Washington column moves with Washington's own rules, so the two do not scale together.

| Net 1099 profit | Per quarter to the IRS | Per quarter to Washington | Effective rate |
|---|---|---|---|
| $25,000 | $923 | , | 16.4% |

Staying inside the safe harbor
Payments are required once you expect to owe $1,000 or more, which the $50,000 example above does, at $9,732 for the year. Two targets avoid a penalty and you need only the lower; the hub explains both routes and the penalty.

| State | State tax per quarter | vs Washington |
|---|---|---|
| Idaho | $596 | +$596 a quarter |

What this schedule assumes
- Single filer, standard deduction, net 1099 profit after expenses, no W-2 withholding.
- Four equal payments rather than annualised income.
- Washington collects no income tax, so the state column is empty by design and the federal voucher is your only one.
