Tax Year 2019 Idaho Income Tax Brackets
|Tax Bracket||Tax Rate|
|Tax Bracket||Tax Rate|
Both Idaho's tax brackets and the associated tax rates were last changed two years prior to 2020 in 2018. Idaho's tax brackets are indexed for inflation, and are updated yearly to reflect changes in cost of living.
Idaho has seven marginal tax brackets, ranging from 1.13% (the lowest Idaho tax bracket) to 6.93% (the highest Idaho tax bracket). Each marginal rate only applies to earnings within the applicable marginal tax bracket .
In Idaho, different tax brackets are applicable to different filing types. Married couples filing their Idaho income tax return jointly will usually have wider tax brackets than those filing separately or as an individual.
How do Idaho tax brackets work?
Technically, you don't have just one "tax bracket" - you pay all of the Idaho marginal tax rates from the lowest tax bracket to the tax bracket in which you earned your last dollar. For comparison purposes, however, your Idaho 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 Idaho tax brackets using this model:
|For earnings between $0.00 and $1,541.00, you'll pay 1.13%|
|For earnings between $1,541.00 and $3,081.00, you'll pay 3.13% plus $17.34|
|For earnings between $3,081.00 and $4,622.00, you'll pay 3.63% plus $65.46|
|For earnings between $4,622.00 and $6,162.00, you'll pay 4.63% plus $121.32|
|For earnings between $6,162.00 and $7,703.00, you'll pay 5.63% plus $192.55|
|For earnings between $7,703.00 and $11,554.00, you'll pay 6.63% plus $279.23|
|For earnings over $11,554.00, you'll pay 6.93% plus $534.36|
|For earnings between $0.00 and $3,082.00, you'll pay 1.13%|
|For earnings between $3,082.00 and $6,162.00, you'll pay 3.13% plus $34.67|
|For earnings between $6,162.00 and $9,244.00, you'll pay 3.63% plus $130.92|
|For earnings between $9,244.00 and $12,324.00, you'll pay 4.63% plus $242.65|
|For earnings between $12,324.00 and $15,406.00, you'll pay 5.63% plus $385.10|

Idaho Income Tax Estimator
You can use the income tax estimator to the left to calculate your approximate Idaho and Federal income tax based on the most recent tax brackets.
Keep in mind that this estimator assumes all income is from wages, assumes the standard deduction, and does not account for tax credits.

Idaho Tax Deductions
When calculating your Idaho income tax, keep in mind that the Idaho 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 Idaho standard deduction, exemptions for dependants, business expenses, etc.
Remember that Idaho 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 Idaho income tax return.

Idaho Standard Deductions & Personal Exemption Amounts
In addition to marginal tax brackets, one of the major features of the Idaho income tax is deductions. The three most common deductions encountered by taxpayers are the Idaho Standard Deduction, the Idaho Personal Exemption, and the Idaho Dependent Deduction. The current values of these deductions for tax year 2020 are as follows:
|Standard Deduction (Single)||Standard Deduction (MFJ)||Personal Exemption||Dependant Exemption|
The standard deduction, which Idaho has, is a deduction that is available by default to all taxpayers who do not instead choose to file an itemized deduction. Essentially, it translates to $12,000.00 per year of tax-free income for single Idaho taxpayers, and $24,000.00 for those filing jointly.
The Personal Exemption, which is not supported by the Idaho 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 Idaho's and may have different rules.
