Side Income Tax Calculator for North Dakota

Side income in North Dakota is subject to federal income tax at your marginal rate, self-employment tax if applicable, and up to 1.95% North Dakota state income tax. Because side income typically stacks on top of your W-2 salary, it is often taxed at your highest marginal rates. 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 North Dakota.

North Dakota uses a graduated income tax with brackets ranging from 0-1.95%. Lower income is taxed at lower rates, with the 1.95% 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. North Dakota does not have local income taxes, so the state graduated rate is the total state-level income tax burden.

The table below shows what you actually keep at five salary levels in North Dakota, accounting for federal tax, FICA, and North Dakota's graduated (0-1.95%) state tax.
