Income Tax in Idaho

Idaho uses a flat 5.8% state income tax on taxable income.

Structure:

Single flat rate
Applies to wages, bonuses, sponsorship income, and all/any other gross pass-through income earned within the state.
Residents taxed on worldwide income

For professional athletes:

Higher than Utah (4.55%) and Colorado (4.40%)
Lower than high-tax states like California (13.3%)
Simple modeling due to flat structure

Example

An NBA player earning $25 million while domiciled in Idaho would owe approximately $1,450,000 in state income tax. Compared to California, that’s roughly $1.7-$2+ million less per year in state tax exposure.

Over a 4-year contract, the difference could exceed $7+ million in retained net income. Idaho sits in the moderate-to-upper tax tier among all states.

Sales Tax

Idaho’s statewide base sales tax is 6%.

Local option taxes are limited and generally apply in specific resort areas, meaning most combined rates remain near 6%–6.5%.

For high-income athletes:

Moderate consumption tax exposure
Lower combined rates than many major metro states

Example

Buying a $200,000 vehicle in Boise at 6% would trigger roughly $12,000 in sales tax. Compared to California or Washington urban areas, Idaho’s consumption tax burden is noticeably lower.

While still not as nice as Oregon’s no sales tax levy, the difference of that 3-3.5% saved on assets and liability purchases means the difference in a 3-3.5% depreciation rate and appreciation expectations as well.

Jock Tax

Idaho taxes income earned from work performed in the state.

Visiting athletes owe Idaho income tax on duty days played in-state.
Idaho-domiciled athletes owe 5.8% on worldwide income.

Idaho does not currently host major NFL, NBA, MLB, or NHL franchises, so jock tax exposure for visiting pro athletes is limited primarily to minor league or special events.

However, Idaho residents competing in other states will still owe taxes to those states based on duty days. Flat structure simplifies modeling but does not eliminate multi-state obligations.

Cost of Living and Housing

Idaho’s cost of living has risen significantly, particularly in the Boise metro area. Lifestyle budgets:

Boise metro: $90k–$150k+ annually depending on property and discretionary spending
Smaller cities: more moderate cost profile

Housing

Statewide median home price: ~$450k–$500k
Boise 3-bed/2-bath: ~$500k+
Resort areas (Sun Valley): substantially higher

Compared to California, Idaho offers:

Lower income tax
Lower housing costs
Lower overall tax drag

But compared to Utah or Colorado, Idaho’s flat rate is slightly higher.

Property Tax

Idaho has one of the lowest property tax burdens in the U.S., with an effective real estate tax rate of roughly 0.49% as of early 2026.

Taxes are levied by local counties for services, not the state, and are calculated based on market value minus exemptions, such as a primary residence homeowner’s exemption.

For athletes playing in Idaho, Washington, Montana or even Oregon, establishing residency in Idaho can be a major net income retaining factor.

Washington state has one of the highest property tax rates in the nation, as well as one of the most expensive housing markets as well. Oregon has taken a sharp decline in recent years economically and Montana is even more underdeveloped than Idaho itself.

So, university athletes and pros in Seattle or Portland could build their net worth faster, retain more net earnings and see higher appreciation rates and investment portfolio diversification than those who establish residency in one of the potato states neighbor states.

Residency Rules

Athletes establishing domicile in Idaho must:

Obtain Idaho driver’s license
Register vehicles in-state
Register to vote
Establish primary residence
Demonstrate intent to remain

Idaho taxes residents on worldwide income at 5.8%.

Example

A professional athlete establishing Idaho residency would owe 5.8% on salary and endorsement income, but still owe jock tax to other states for away games. Residency establishment is generally straightforward compared to high-audit states.

Why Idaho Is Moderately Tax Efficient

Flat 5.8% income tax
Moderate sales tax
No extreme progressive brackets
Lower housing costs than coastal states
Fewer major pro franchises (lower jock tax frequency)

Idaho is not a zero-tax state, but it avoids the severe progressive exposure of states like California and New York.

For athletes focused on balancing moderate taxation and lower cost of living, Idaho presents a stable mid-tier tax environment.
