How do I calculate Alabama withholding tax manually?
Follow these steps:
- Determine gross pay for the period.
- Subtract pre-tax deductions (401(k), HSA, etc.).
- Apply the standard deduction prorated for the pay period (e.g., $2,500/52 = $48.08 per week for single filers).
- Use the Alabama Withholding Tables to find the tax based on taxable income and pay frequency.
- For annual income over $6,000 ($12,000 joint), apply 5% to the excess.
Example: Bi-weekly pay of $2,000 with $100 401(k) deduction:
Taxable income = $2,000 – $100 – ($2,500/26) ≈ $1,846
Tax = $38.46 (from wage bracket tables) + 5% on amount over $6,000 annualized.
