The Hawaii 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 Hawaii |
|---|---|---|---|
| April 15, 2026 | Jan 1 - Mar 31 | $2,190 | $696 |
| June 16, 2026 | Apr 1 - May 31 | $2,190 | $696 |

| Year | $8,759 | $2,783 | |
The Hawaii side of each payment
Hawaii taxes the same 1099 profit on 12 graduated brackets topping out at 11%, so a second payment goes to the state each quarter, about $696 on the $50,000 example, against $3,093 of Hawaii income tax for the year.
The 2026 dataset carries the federal 1040-ES dates but not state-specific due dates, so confirm Hawaii'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 Hawaii
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 Hawaii column moves with Hawaii'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 Hawaii | Effective rate |
|---|---|---|---|
| $25,000 | $923 | $292 | 21.6% |
| $50,000 | $2,190 | $696 | 25.6% |
| $100,000 | $5,032 | $1,557 | 29.3% |
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 $12,825 for the year. Two targets avoid a penalty and you need only the lower; the hub explains both routes and the penalty.

Hawaii runs a state disability insurance program: varies. Hawaii TDI mandatory for employees.
What a quarter costs in the states Hawaii borders
Hawaii shares no land border, so there is no commuter comparison to make. But the move-to-and-from comparison still holds. On $50,000, Hawaii charges $3,379 against $0 in Texas and $2,495 in New York.
| State | State tax per quarter | vs Hawaii |
|---|---|---|
| Texas | No income tax | −$760 a quarter |
| Florida | No income tax | −$760 a quarter |
| California | $302 | −$458 a quarter |
| New York | $561 | −$199 a quarter |
- Texas has no income tax at all, so the same work done there costs $3,379 less in state tax than it does in Hawaii.
- Florida has no income tax at all, so the same work done there costs $3,379 less in state tax than it does in Hawaii.
- California would take $2,036 less, $1,343 against Hawaii's $3,379.
- New York would take $884 less, $2,495 against Hawaii's $3,379.
What this schedule assumes
- Single filer, standard deduction, net 1099 profit after expenses, no W-2 withholding.
- Four equal payments rather than annualised income.
- Hawaii due dates are not in the 2026 dataset, the dates shown are the federal ones.
Hawaii quarterly tax questions
How much should I send each quarter in Hawaii?
On $50,000 of net 1099 profit as a single filer, about $2,190 to the IRS plus roughly $696 to Hawaii. That is 90% of this year's liability, split four ways.
Does Hawaii use the same due dates as the IRS?
Hawaii 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 Hawaii's own schedule with its tax agency before assuming they line up.
