Idaho withholding comes down to one rate and one threshold. Pay up to a zero-tax limit, set by whether you are withheld as single or married, carries no Idaho tax at all; everything above it is withheld at a single flat rate. The State Tax Commission issued new tables partway through the year and told employers to use them straight away, without going back to adjust earlier paychecks, so a mid-year change on your stub is expected. The calculator uses the current tables for the whole year.
One thing that used to lower Idaho withholding no longer does. The ID W-4 still has a line for child tax credit allowances, but Idaho’s child tax credit has expired, and the current tables give the same result whatever number appears there. The form’s other choices still count: status C lets a married person be withheld at the single rate, and you can add a fixed extra amount to each paycheck or write “Exempt” if you expect to owe no Idaho tax.
Idaho has no city or county income taxes and no employee payroll levy, so the only state line on a pay stub is income tax. Pre-tax 401(k) and HSA contributions reduce Idaho taxable wages along with federal ones. Hourly workers fall under the federal overtime rules; the hourly paycheck calculator handles that case.
Cross-border work is common around Idaho’s edges: Coeur d’Alene sits next to Spokane, the Treasure Valley runs up to the Oregon line, and Utah lies just south of Idaho’s southeastern towns. Idaho has no reciprocal agreements with any of those states. Idaho residents working in Oregon or Utah have that state’s tax withheld, counted against Idaho withholding, while Washington has no income tax, so for Idaho residents working there, Idaho is the only state taxing that pay as income.
How Idaho taxes your paycheck
State income tax withholding
On the tax return, Idaho taxes income at a single rate of 5.3% on income above a band that is not taxed at all. Employers withhold at the same rate, on all taxable wages, with no allowances. The withholding figures here follow Idaho's own instructions for employers.
For a single filer paid every two weeks, Idaho withholds 2.4% of a $30,000 salary and 4.7% of $150,000:
| Salary | Idaho tax withheld | Share of pay |
|---|---|---|
| $30,000 | $728 | 2.4% |
| $50,000 | $1,794 | 3.6% |
| $75,000 | $3,120 | 4.2% |
| $100,000 | $4,446 | 4.4% |
| $150,000 | $7,098 | 4.7% |
City and county taxes
No Idaho city or county withholds income tax from wages, so state income tax is the only Idaho line on your pay stub.
Living in one state and working in another
Idaho has no reciprocal agreements, so it withholds from everyone who works there, wherever they live. If you live elsewhere, your home state may withhold too, usually less a credit for the Idaho tax.
If you live in Idaho and the job is across a state line, both states withhold, but Idaho takes the other state's tax off its own amount. The calculator does this when you enter both states, and the guide to reciprocity agreements explains where neighboring states skip withholding altogether.
