W-4 Withholding Calculator for Oregon

Getting your W-4 right in Oregon is important because you need to coordinate federal withholding with Oregon's graduated (4.75-9.9%) state withholding. If your W-4 is set too conservatively, you lend the government an interest-free loan; too aggressively, and you face an underpayment penalty. Workers in Oregon localities with income tax need to account for that additional withholding layer. This calculator helps you dial in the right federal withholding amount given your Oregon state tax situation.

Oregon uses a graduated income tax with brackets ranging from 4.75-9.9%. Lower income is taxed at lower rates, with the 9.9% top rate applying only to income in the highest bracket. This progressive structure means your effective state tax rate is always lower than the top marginal rate. In addition, some Oregon localities impose their own income tax, which stacks on top of the state rate. This is especially notable in areas like certain cities and counties. Always check your local rate when calculating total tax liability.

The table below shows what you actually keep at five salary levels in Oregon, accounting for federal tax, FICA, and Oregon's graduated (4.75-9.9%) state tax plus estimated local taxes.
