Understanding Idaho Self-Employed Taxes 2025
Self-employed individuals in Idaho are responsible for paying several types of taxes. These include federal self-employment taxes and Idaho state income taxes. Knowing your obligations ensures compliance and prevents unexpected penalties.
Federal Self-Employment Taxes
The federal self-employment tax covers Social Security and Medicare contributions. Your self-employment tax is calculated based on net earnings, which is total business income minus deductible business expenses.
- Social Security tax is 12.4 percent on the first $168,600 of net income in 2025
- Medicare tax is 2.9 percent on all net income
- Additional Medicare tax of 0.9 percent applies to earnings over $200,000 for single filers and $250,000 for married couples filing jointly
Half of your self-employment tax is deductible when calculating adjusted gross income. Using accurate records and tax software ensures proper calculation.
Idaho State Income Tax for Self-Employed Individuals
Idaho self-employed residents must pay state income tax based on taxable income, which includes net business income. For 2025–2026, Idaho’s income tax brackets are:
| Taxable Income (Single) | Tax Rate |
| $0 – $3,500 | 1.0% |
| $3,501 – $7,000 | 3.0% |
| $7,001 – $10,500 | 4.5% |
| $10,501 – $16,500 | 6.0% |
| $16,501 – $33,000 | 6.5% |
| Over $33,000 | 6.5% plus 0.5% for income exceeding $33,000 |
Married couples filing jointly double the thresholds. Idaho’s progressive system ensures higher earners pay more in taxes.
