Tax Planning for Physicians in Idaho (2026)

Physicians in Idaho face a top rate of 5.3% on top of the 37% federal bracket and payroll taxes. This guide summarizes the 2026 Idaho rules that matter most to doctors, dentists and practice owners.

Idaho income tax rates for 2026

Idaho has a flat income tax of 5.3% for 2026 on taxable income above $4,811.

Pass-through entity tax (SALT workaround)

Yes. The state has an elective pass-through entity tax (PTET) that partnerships and S corporations can use to deduct state income tax at the entity level.

For physician practice owners, the PTET matters more in 2026 because the federal SALT deduction for individuals phases back down toward $10,000 once modified AGI passes $505,000. Read our guide to the pass-through entity tax for physicians.

Local income taxes
