OVERVIEW
Idaho taxes income at 5.3% (effective January 1, 2025) above a small zero-rate bracket — dramatically lower than Oregon's progressive rates that reach 9.9%. A $100,000 single filer pays $7,148 in Oregon income tax versus $4,185 in Idaho, saving $2,963 per year in Idaho. Oregon's major advantage is zero sales tax — one of only five states with none — while Idaho levies 6% (with a $120/person annual grocery credit to offset food costs). Idaho's property tax averages just 0.50% with a generous 50% homestead exemption, versus Oregon's 0.81%. Oregon's estate tax — triggered at just $1 million — is a critical planning concern for homeowners and retirees. Portland-area residents face even higher effective rates from Metro SHS (1%) and Multnomah County PFA taxes (1.5%-3%). For most earners, Idaho wins on income tax; renters and big spenders benefit from Oregon's sales tax exemption.

FAQ

Frequently Asked Questions

How much will I save moving from Oregon to Idaho?

At $100,000 income, you save $2,963 per year in state income tax moving from Oregon to Idaho. Idaho's 5.3% rate produces a $4,185 tax bill on $100K versus Oregon's $7,148. Over 10 years, that is $29,630 in cumulative savings — before factoring in sales tax and property tax differences. At $150,000, Idaho saves you $5,970 per year.

What are the Oregon income tax brackets for 2026?

Oregon has four progressive brackets: 4.75% on income up to roughly $10,200; 6.75% from $10,200 to $25,500; 8.75% from $25,500 to $125,000; and 9.9% above $125,000. The state standard deduction is just $2,420 for single filers — much lower than the federal $16,100 — which means more income is exposed to these rates. A $263 personal exemption credit (2026 estimate) reduces the final bill.

What is Idaho's income tax rate?

Idaho's income tax rate is 5.3%, effective January 1, 2025 (down from 5.695%), applied to taxable income above a zero-rate bracket ($4,811 single, $9,622 married in the 2025 schedule). Single filers deduct the federal standard deduction ($16,100) and there is no personal exemption. This makes Idaho's effective rate on $100K income just 4.19%, well below Oregon's 8.01% at the same income.

Oregon has no sales tax — does that offset Idaho's lower income tax?

Partially. Oregon is one of five states with no sales tax, which saves a typical household $1,000-$2,500 per year depending on spending habits. Idaho's 6% sales tax applies to most purchases (including groceries), though a $120 per-person annual grocery credit helps offset food costs. For a $100K earner who spends $40,000 on taxable goods, Idaho's 6% sales tax adds roughly $2,400 — reducing the $2,963 income tax advantage to about $1,415. High spenders should run the full math.

What about Oregon's estate tax? Why does it matter?

Oregon's estate tax applies to estates above $1 million — an extraordinarily low threshold compared to the $15 million federal exemption (2026). Rates run from 10% to 16%. Many Oregon homeowners in the Portland metro, where median home values exceed $500,000, find their total estate (home + retirement accounts + savings) can easily exceed $1 million. Idaho has no state estate tax, making it significantly more favorable for estate planning, especially for retirees.

What extra taxes do Portland-area Oregon residents pay?

Portland metro residents face stacked local income taxes beyond the state rate. The Metro Supportive Housing Services (SHS) tax adds 1% on income above $125,000 for single filers. Multnomah County's Preschool for All (PFA) tax adds 1.5% on income from $125,000 to $250,000, rising to 3% above $250,000. A Portland-area resident earning $150,000 could pay an effective combined rate exceeding 10%, making the gap with Idaho's 5.3% even larger.

How do Oregon and Idaho property taxes compare?

Idaho has a significant property tax advantage. Idaho's effective average property tax rate is about 0.50%, compared to Oregon's 0.81%. More importantly, Idaho offers a 50% homestead exemption on primary residences — up to $125,000 off the assessed value — that reduces the taxable base for most homeowners. On a $400,000 home, Oregon property tax runs roughly $3,240/year versus Idaho's $2,000/year, a $1,240 annual saving.

Is Boise cheaper to live in than Portland?

Yes, significantly. Boise's median home price is approximately $440,000-$470,000 versus Portland's $530,000-$560,000. Boise has grown rapidly, but its overall cost of living — including housing, dining, and services — remains 15-20% lower than Portland. Combined with Idaho's lower income tax, property tax, and no estate tax risk, the total financial picture for a $100K earner in Boise is materially better than Portland, even after accounting for Oregon's no-sales-tax advantage.
