Side Income Tax Calculator for Oregon

Side income in Oregon is subject to federal income tax at your marginal rate, self-employment tax if applicable, and up to 9.9% Oregon state income tax. Because side income typically stacks on top of your W-2 salary, it is often taxed at your highest marginal rates. Local income taxes in some Oregon jurisdictions add further cost. The combined marginal rate on side income can easily exceed 40% for mid-to-high earners. This calculator breaks down exactly what you keep from each dollar of side income in Oregon.

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.
