Alabama rules for construction & trades
- State income tax (2026)
- Alabama has a graduated state income tax for 2026: 2% to 5% (top rate starts at $3,000 for single filers). Single, head of family, and married filing separately: 2% on the first $500 of taxable income, 4% on the next $2,500, and 5% on taxable income over $3,000. Married filing jointly: 2% on the first $1,000, 4% on the next $5,000, 5% over $6,000.
- State estimated tax
- You generally must pay estimated tax if you expect to owe at least $500 for 2026 after withholding and credits, and your withholding plus credits will be less than the smaller of 90% of your 2026 tax or 100% of your 2025 tax (110% if your 2025 Alabama AGI was over $150,000). Same dates as federal: April 15, June 15, and September 15, 2026, and January 15, 2027 (farmers with at least two-thirds of gross income from farming may pay by January 15, 2027). Form 40ES.
- Alabama business privilege tax
- An annual tax on LLCs (including disregarded single-member LLCs, which file Form PPT when the owner is not itself subject to the tax) and corporations. It is $0.25 to $1.75 per $1,000 of Alabama net worth, with the rate set by federal taxable income apportioned to Alabama, up to a $15,000 maximum. For tax year 2026, a business that would only owe the $100 minimum tax has no filing requirement.
- Alabama Portable Benefits Act (Act 2025-119)
- Creates voluntary portable benefit accounts for independent contractors and gig workers to fund health, income-replacement, life insurance, and retirement benefits. For tax years beginning after December 31, 2025, contractors can deduct 100% of contributions (their own and those from hiring parties) on their Alabama return, and hiring parties can deduct 100% of what they contribute. Courts cannot use a hiring party's contributions as a factor in deciding whether a worker is an employee.
Federal rules for 2026
W-2 or 1099 changes everything
On a W-2 your employer withholds tax and may offer a retirement plan. As a 1099 subcontractor you pay self-employment tax and quarterly estimates, but you can deduct tools, materials and job-site driving.
Tools and equipment
Tools, equipment, safety gear and work vehicles used for business are deductible; larger purchases can often be written off in the year you buy them.
Overtime deduction for W-2 workers
Non-exempt W-2 workers can deduct the overtime premium they are paid, up to $12,500 a year ($25,000 joint) from 2025 through 2028, subject to an income phase-out.
Quarterly estimated taxes
No one withholds tax from self-employment income, so you generally pay estimates four times a year if you expect to owe $1,000 or more. For 2026 income the federal dates are April 15, June 15 and September 15, 2026, and January 15, 2027. Paying 100% of last year's tax (110% if your AGI was over $150,000) in four equal installments avoids the underpayment penalty.
A worked example
