The Missouri 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 Missouri |
|---|---|---|---|
| April 15, 2026 | Jan 1 - Mar 31 | $2,190 | $464 |

The Missouri side of each payment
Missouri taxes the same 1099 profit on 8 graduated brackets topping out at 4.8%, so a second payment goes to the state each quarter, about $464 on the $50,000 example, against $2,060 of Missouri income tax for the year.
The 2026 dataset carries the federal 1040-ES dates but not state-specific due dates, so confirm Missouri'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 Missouri
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 Missouri column moves with Missouri'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 Missouri | Effective rate |
|---|---|---|---|
| $25,000 | $923 | $213 | 20.2% |
| $50,000 | $2,190 | $464 | 23.6% |
| $100,000 | $5,032 | $965 | 26.7% |
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 $11,792 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 Missouri
Missouri is one of the twelve states that still taxes Social Security benefits, which matters if you are drawing benefits alongside self-employment income.
