Alabama repealed its income tax for state and local public employees in 2021, so most Alabama 1099 contractors can deduct the full federal income tax they paid as a SALT item. The state top marginal rate is 5.00% and the constitutional amendment capping the top rate at 5% means it rarely moves.
Local taxes: Alabama cities and counties levy their own occupational taxes on top of the state rate, typically 0.5% to 4% of wages. Self-employed contractors are often charged these as business license fees rather than income tax.
State revenue agency: Alabama Department of Revenue.Alabama requires estimated tax payments only when you owe $200 or more after withholding, and due dates follow the federal 1040-ES schedule. There is no separate state voucher form.
Tax Strategy for trade contractors
Trades contractors deduct materials, tools, vehicles, insurance, and licensing, and the vehicle deduction is often the largest. A work van used exclusively for the business supports either the standard mileage rate or a full expense deduction including depreciation, and a dedicated trades vehicle makes the actual-expense method far more favourable than it would for a mixed-use car. Worker's compensation premiums and tools that fall under $2,500 are also deductible.
Trades income follows the construction calendar closely, with a hard winter slowdown and a summer surge. Quarterly income can swing by a factor of three between peak and off-peak, so base vouchers on the trailing twelve months and hold back more aggressively during the busy season rather than spending it.
To avoid underpayment penalties, pay at least 90% of your current-year tax, or 100% of last year's total tax — 110% if your prior-year AGI was above $150,000.

The percentage is measured against gross income rather than net profit because that is the number that actually reaches your bank account and the number you can safely divert.

Because Alabama taxes self-employment income at 4.5%, each deduction reduces both your federal and your Alabama liability, so a deduction is worth more than its face value.
