Quarterly Tax Estimator for Washington

In Washington, quarterly estimated tax payments only need to cover federal income tax and self-employment tax, since there is no state income tax to account for. This simplifies your quarterly planning: divide your expected annual federal liability by four and pay by the IRS deadlines (April 15, June 15, September 15, January 15). Use this estimator to calculate your quarterly amounts so you avoid the underpayment penalty, which applies if you owe more than $1,000 at filing time.

Washington is one of nine states with no personal income tax. Residents keep every dollar of earnings from state-level taxation, though the state generates revenue through other means such as sales taxes, property taxes, and in some cases severance taxes on natural resources. Washington does impose a 7% tax on capital gains exceeding $270,000, so high-net-worth investors should factor that in.

The table below shows what you actually keep at five salary levels in Washington, accounting for federal tax, FICA, and zero state income tax.
