How $20 an hour is taxed in Idaho

1. Federal income tax: $2,812
Start with $41,600 of wages and subtract the $16,100 standard deduction. That leaves $25,500 of taxable income, taxed in brackets:
| Taxable income band | Rate | Income taxed | Tax |
|---|---|---|---|
| $0 to $12,400 | 10% | $12,400 | $1,240 |
| $12,400 to $50,400 | 12% | $13,100 | $1,572 |
| Federal income tax | $2,812 | ||
2. Idaho income tax: $1,097
Idaho starts from federal taxable income, $25,500. That leaves $25,500 of Idaho taxable income.
| Taxable income band | Rate | Income taxed | Tax |
|---|---|---|---|
| $0 to $4,811 | 0% | $4,811 | $0 |
| Over $4,811 | 5.3% | $20,689 | $1,097 |
| Idaho income tax | $1,097 | ||
3. Social Security and Medicare: $3,182
Social Security is 6.2% of wages up to the $184,500 wage base ($2,579), and Medicare is 1.45% of all wages ($603).
Result: $41,600 minus $7,091 in total tax leaves $34,509 a year, an effective tax rate of 17.0%.
