The Alabama payment schedule on $50,000
A single filer with $50,000 of net 1099 profit, taking the standard deduction and paying 90% of this year's liability:
| Due | Income earned | To the IRS | To Alabama |
|---|---|---|---|
| April 15, 2026 | Jan 1 - Mar 31 | $2,190 | $514 |
| June 16, 2026 | Apr 1 - May 31 | $2,190 | $514 |

| January 15, 2027 | Sep 1 - Dec 31 | $2,190 | $514 |
| Year | $8,759 | $2,055 | |
The Alabama side of each payment
Alabama taxes the same 1099 profit on 3 graduated brackets topping out at 5%, so a second payment goes to the state each quarter, about $514 on the $50,000 example, against $2,283 of Alabama income tax for the year.
The 2026 dataset carries the federal 1040-ES dates but not state-specific due dates, so confirm Alabama's schedule and voucher with its tax agency, several states do not match the federal calendar exactly.
What each quarter costs at three income levels in Alabama
A single filer taking the standard deduction, at three levels of net profit. The federal column moves with the self-employment tax and the federal brackets; the Alabama column moves with Alabama's own rules, so the two do not scale together. Use the calculator above for the other filing statuses:
| Net 1099 profit | Per quarter to the IRS | Per quarter to Alabama | Effective rate |
|---|---|---|---|
| $25,000 | $923 | $252 | 20.9% |
| $50,000 | $2,190 | $514 | 24.0% |
| $100,000 | $5,032 | $1,037 | 27.0% |
Staying inside the safe harbor
Payments are required once you expect to owe $1,000 or more, which the $50,000 example above does, at $12,015 for the year. Two targets avoid a penalty and you need only the lower; the hub explains both routes and the penalty.
What the rate alone doesn't tell you about Alabama
Alabama also has local income tax that the estimate above does not model, some cities: Birmingham 1%, etc.. Add it separately for where you live and work.
What a quarter costs in the states Alabama borders
On $50,000, Alabama charges $2,460 of state income tax. Of the 4 states it borders, Florida is the lightest at nothing at all and Georgia the most expensive at $2,595, a spread of $2,595 on the same income.
| State | State tax per quarter | vs Alabama |
|---|---|---|
| Florida | No income tax | −$554 a quarter |
| Tennessee | No income tax | −$554 a quarter |
| Mississippi | $450 | −$104 a quarter |
| Georgia | $584 | +$30 a quarter |
- Florida has no income tax at all, so the same work done there costs $2,460 less in state tax than it does in Alabama.
- Tennessee has no income tax at all, so the same work done there costs $2,460 less in state tax than it does in Alabama.
- Mississippi would take $460 less, $2,000 against Alabama's $2,460.
- Georgia would take $135 more, $2,595 against Alabama's $2,460.
What this schedule assumes
- Single filer, standard deduction, net 1099 profit after expenses, no W-2 withholding.
- Four equal payments rather than annualised income.
- Alabama due dates are not in the 2026 dataset, the dates shown are the federal ones.

On $50,000 of net 1099 profit as a single filer, about $2,190 to the IRS plus roughly $514 to Alabama. That is 90% of this year's liability, split four ways.
Does Alabama use the same due dates as the IRS?
Alabama requires its own estimated payments, but the 2026 dataset carries only the federal 1040-ES dates (April 15, 2026, June 16, 2026, September 15, 2026, January 15, 2027). Confirm Alabama's own schedule with its tax agency before assuming they line up.
