Quarterly Tax Estimator for Oregon

Quarterly estimated payments in Oregon must cover both your federal and state obligations. Oregon uses graduated rates (4.75-9.9%), and most states require their own quarterly payment schedule that may differ from the IRS dates. If your Oregon locality imposes income tax, you may need a third set of quarterly payments. This estimator pre-loads Oregon's tax rates so you can calculate both federal and state quarterly amounts in one place, avoiding underpayment penalties at both levels.

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.
