Tax Year 2018 North Dakota Income Tax Brackets
|Tax Bracket||Tax Rate|
|Tax Bracket||Tax Rate|
North Dakota's income tax brackets were last changed two years prior to 2018 for tax year 2016, and the tax rates were previously changed in 2014. North Dakota's tax brackets are indexed for inflation, and are updated yearly to reflect changes in cost of living.
North Dakota has five marginal tax brackets, ranging from 1.1% (the lowest North Dakota tax bracket) to 2.9% (the highest North Dakota tax bracket). Each marginal rate only applies to earnings within the applicable marginal tax bracket , which are the same in North Dakota for single filers and couples filing jointly.
The Federal Income Tax, by contrast, has different tax brackets for Single, Married Filing Jointly, and Head of Household taxpayers.
How do North Dakota tax brackets work?
Technically, you don't have just one "tax bracket" - you pay all of the North Dakota marginal tax rates from the lowest tax bracket to the tax bracket in which you earned your last dollar. For comparison purposes, however, your North Dakota tax bracket is the tax bracket in which your last earned dollar in any given tax period falls.
You can think of the bracketed income tax as a flat amount for all of the money you earned up to your highest tax bracket, plus a marginal percentage of any amount you earned over that. The chart below breaks down the North Dakota tax brackets using this model:
|For earnings between $0.00 and $38,700.00, you'll pay 1.1%|
|For earnings between $38,700.00 and $93,700.00, you'll pay 2.04% plus $425.70|
|For earnings between $93,700.00 and $195,450.00, you'll pay 2.27% plus $1,547.70|
|For earnings between $195,450.00 and $424,950.00, you'll pay 2.64% plus $3,857.43|
|For earnings over $424,950.00, you'll pay 2.9% plus $9,916.23|
|For earnings between $0.00 and $64,650.00, you'll pay 1.1%|
|For earnings between $64,650.00 and $156,150.00, you'll pay 2.04% plus $711.15|
|For earnings between $156,150.00 and $237,950.00, you'll pay 2.27% plus $2,577.75|
|For earnings between $237,950.00 and $424,950.00, you'll pay 2.64% plus $4,434.61|
|For earnings over $424,950.00, you'll pay 2.9% plus $9,371.41|

North Dakota Tax Deductions
When calculating your North Dakota income tax, keep in mind that the North Dakota state income tax brackets are only applied to your adjusted gross income (AGI) after you have made any qualifying deductions.
Qualifying deductions might include an itemized deduction, the North Dakota standard deduction, exemptions for dependants, business expenses, etc.
Remember that North Dakota may have very different deduction laws from the Federal Income Tax, so you may have to write a whole new list of deductions for your North Dakota income tax return.

North Dakota Standard Deductions & Personal Exemption Amounts
In addition to marginal tax brackets, one of the major features of the North Dakota income tax is deductions. The three most common deductions encountered by taxpayers are the North Dakota Standard Deduction, the North Dakota Personal Exemption, and the North Dakota Dependent Deduction. The current values of these deductions for tax year 2018 are as follows:
|Standard Deduction (Single)||Standard Deduction (MFJ)||Personal Exemption||Dependant Exemption|
The standard deduction, which North Dakota does not have, is a deduction that is available by default to all taxpayers who do not instead choose to file an itemized deduction.
The Personal Exemption, which is not supported by the North Dakota income tax, is an additional deduction you can take if you (and not someone else) are primarily responsible for your own living expenses. Likewise, you can take an additional dependent exemption for each qualifying dependent (like a child or family member), who you financially support.
The Federal income tax also has a standard deduction, personal exemptions, and dependant deductions, though they are different amounts than North Dakota's and may have different rules.
