How much Idaho tax do I pay on $75,000?
Idaho has a flat 5.3% income tax in 2026. A single filer on $75,000 pays $2,867 Idaho tax, $7,670 federal tax and $5,738 FICA, keeping $58,725 a year ($4,894 a month, $2,259 biweekly). These 2026 figures use the 2025 zero-rate thresholds because final 2026 thresholds are not yet published, and cover wages only.
Key takeaways
- Idaho charges a flat 5.3% on Idaho taxable income in 2026 — there are no Idaho brackets to climb.
- Subtract the federal standard deduction ($16,100 single; $32,200 married filing jointly) and the zero-rate threshold ($4,811 single; $9,622 joint, using 2025 thresholds because final 2026 thresholds are not yet published) before applying 5.3%.
- There is no personal exemption and no local income tax in Idaho.
- Social Security benefits are not taxed in Idaho; this wage calculator does not model retirement income.
- The $155-per-person grocery (food) tax credit is not modelled here — see the FAQ below.

What is Idaho’s income tax rate in 2026?
Idaho has a flat income tax rate of 5.3% in 2026 under Idaho Code 63-3024 and HB 40, which set the flat rate from 2025. Idaho has no tax brackets in 2026: every dollar of Idaho taxable income is taxed at the same 5.3%, whether you earn $30,000 or $200,000.
Idaho taxable income is your gross wages minus the federal standard deduction ($16,100 single; $32,200 married filing jointly), minus a zero-rate threshold. Income below the threshold is taxed at 0%. The thresholds used here are $4,811 single and $9,622 married filing jointly — the 2025 thresholds, used for this 2026 estimate because the Idaho State Tax Commission has not yet published final 2026 zero-rate thresholds. If the final 2026 thresholds differ, your Idaho tax will differ slightly.
What are the 2026 federal tax brackets?
Federal tax for 2026 (IRS Rev. Proc. 2025-32) uses rates of 10%, 12%, 22%, 24%, 32%, 35% and 37%. The table shows the top of each bracket — the highest income taxed at that rate — for single and married filing jointly filers only. No head-of-household table is included.
| Rate | Single — upper limit | Married filing jointly — upper limit |
|---|---|---|
| 10% | $12,400 | $24,800 |
| 12% | $50,400 | $100,800 |
| 22% | $105,700 | $211,400 |
| 24% | $201,775 | $403,550 |
| 32% | $256,225 | $512,450 |
| 35% | $640,600 | $768,700 |
| 37% | Over $640,600 | Over $768,700 |
How is the $75,000 example worked out?
For a single filer on $75,000 of wages in 2026, using the 2025 zero-rate threshold because final 2026 thresholds have not yet been published:
- Idaho taxable income: $75,000 − $16,100 standard deduction = $58,900; minus the $4,811 zero-rate threshold = $54,089; × 5.3% = $2,867 Idaho tax.
- Federal tax: $7,670 on taxable income of $58,900 (federal standard deduction $16,100).
- FICA: $5,738 (Social Security 6.2% and Medicare 1.45% on $75,000; no Additional Medicare tax below $200,000).
- Take-home pay: $75,000 − $7,670 − $2,867 − $5,738 = $58,725 a year, $4,894 a month and $2,259 biweekly (derived figures).

|---|---|---|---|---|---|---|---|
| $30,000 | $1,420 | $482 | $2,295 | $25,803 | 14.0% | $2,150 | $992 |
| $50,000 | $3,820 | $1,542 | $3,825 | $40,813 | 18.4% | $3,401 | $1,570 |

| $200,000 | $36,734 | $9,492 | $14,339 | $139,435 | 30.3% | $11,620 | $5,363 |
How does Idaho tax compare with federal tax?
Federal tax is progressive: your rate rises as income rises through the 10% to 37% brackets. Idaho tax is flat: once the standard deduction and zero-rate threshold are subtracted, every remaining dollar is taxed at 5.3%. That is why, on $75,000 single, federal tax ($7,670) is much larger than Idaho tax ($2,867), and why the effective tax rate in the table rises with salary even though the Idaho rate never changes — the federal brackets, not Idaho, drive the increase.
What is not included in this calculator?
- The Idaho grocery (food) tax credit of $155 per person is not modelled, because it depends on household size and is claimed separately.
- Alternative Minimum Tax (AMT) is not included.
- Self-employment tax is not included; this calculator covers wages only.
- Credits, itemized deductions, retirement contributions and pre-tax benefits are not included.
- Final 2026 zero-rate thresholds are pending: this 2026 estimate uses the 2025 thresholds ($4,811 single; $9,622 married filing jointly), as stated plainly above. If final 2026 thresholds differ, Idaho tax will differ slightly.
- Social Security benefits are not taxed in Idaho, but this wage calculator does not model retirement income.
- The federal temporary $6,000 senior deduction for taxpayers 65 and older, which phases out above $75,000 / $150,000 MAGI, is not modelled — see the FAQ below.
About the Idaho Income Tax Calculator
How to use
- Enter your pay amount and choose its pay period: Annual, Monthly, Biweekly, Weekly or Hourly.
- Choose Single or Married Filing Jointly.
- Read your annual gross (converted from your pay period), federal tax, Idaho tax, FICA and take-home pay, plus derived monthly, biweekly and weekly take-home figures.
Understanding your results
Take-home pay is your annual gross minus federal tax, Idaho tax and FICA, with each component rounded half-up first. Monthly, biweekly and weekly figures are derived from take-home pay (divided by 12, 26 and 52) and are labelled as derived, because an employer pay period may differ. The effective tax rate is total tax divided by gross pay. The Idaho marginal rate is 5.3%: that is the rate on your next dollar of Idaho taxable income.
How the calculation works
First, your pay is converted to annual gross (Monthly × 12, Biweekly × 26, Weekly × 52, Hourly × 2,080). Federal tax is calculated on gross minus the standard deduction ($16,100 single; $32,200 married filing jointly) using the 2026 brackets in IRS Rev. Proc. 2025-32. Idaho tax is 5.3% × the amount over the standard deduction and the zero-rate threshold ($4,811 single; $9,622 joint, 2025 thresholds used for 2026). FICA is Social Security at 6.2% up to the $184,500 wage base (maximum $11,439), Medicare at 1.45% on all wages, plus Additional Medicare tax at 0.9% only on wages over $200,000 single or $250,000 married filing jointly. All figures are for the 2026 tax year, filed in 2027, on wages.
Idaho Income Tax Calculator FAQs
Is Idaho’s income tax really flat in 2026?
Yes. Idaho has a flat 5.3% income tax in 2026 under Idaho Code 63-3024 and HB 40, which set the flat rate from 2025. There are no Idaho brackets in 2026.
What is the Idaho zero-rate threshold, and why are 2025 thresholds used for 2026?
The zero-rate threshold is the amount of Idaho taxable income taxed at 0% before the 5.3% rate applies: $4,811 single and $9,622 married filing jointly. These are the 2025 thresholds, used for this 2026 estimate because the Idaho State Tax Commission has not yet published final 2026 zero-rate thresholds. If final 2026 thresholds differ, Idaho tax will differ slightly.
What is the standard deduction in Idaho for 2026?
Idaho taxable income starts from gross wages minus the federal standard deduction: $16,100 for single filers and $32,200 for married filing jointly filers in 2026, before the zero-rate threshold is subtracted.
Does Idaho have a personal exemption, and do dependents change the result?
No. Idaho has no personal exemption, so there is no dependents field in this calculator: adding a dependent does not change the Idaho tax calculation here. Other credits or rules outside this wage calculation are not modelled.
Is the Idaho grocery tax credit included?
No. Idaho’s grocery (food) tax credit of $155 per person is not modelled in this calculator, because it depends on household size and is claimed separately. It could reduce tax owed when claimed, but it is not part of the wage calculation above.
Are Social Security benefits taxed in Idaho?
No. Social Security benefits are not taxed in Idaho. This is context only: this calculator covers wages, and does not model retirement income or Social Security benefits.
How is bonus pay treated?
Enter bonus pay as part of your annual gross wages, so it is taxed in this calculator like other wages. In practice, an employer may withhold tax from a bonus differently during the year; your final tax is reconciled when you file, so a bonus can make a single paycheck look different from this annual estimate.
Do I have to file an Idaho tax return?
Whether you must file an Idaho return depends on your income, filing status, residency and other circumstances, so this calculator cannot decide that for you. If you lived or worked in Idaho and had Idaho income, check the Idaho State Tax Commission’s filing guidance for the 2026 tax year, filed in 2027.
Is the federal $6,000 senior deduction for taxpayers 65 and older included?
No. The federal temporary $6,000 senior deduction for taxpayers 65 and older, which phases out above $75,000 / $150,000 MAGI, is not modelled in this calculator. It is explained here only, and taxpayers 65 and older should allow for it separately when estimating federal tax.
Do 401(k) contributions and health insurance premiums change my Idaho take-home pay?
Yes, if you enter them. A 401(k) contribution reduces your federal and Idaho income tax, but it is still subject to Social Security and Medicare tax. Pre-tax health insurance premiums reduce your income tax and your FICA tax. Both are optional in this calculator and default to $0, so leaving them blank gives the same result as before.
