The Wisconsin 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 Wisconsin |
|---|---|---|---|
| April 15, 2026 | Jan 1 - Mar 31 | $2,190 | $467 |
| June 16, 2026 | Apr 1 - May 31 | $2,190 | $467 |

| January 15, 2027 | Sep 1 - Dec 31 | $2,190 | $467 |
| Year | $8,759 | $1,869 | |
The Wisconsin side of each payment
Wisconsin taxes the same 1099 profit on 4 graduated brackets topping out at 7.65%, so a second payment goes to the state each quarter, about $467 on the $50,000 example, against $2,076 of Wisconsin income tax for the year.
The 2026 dataset carries the federal 1040-ES dates but not state-specific due dates, so confirm Wisconsin'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 Wisconsin
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 Wisconsin column moves with Wisconsin'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 Wisconsin | Effective rate |
|---|---|---|---|
| $25,000 | $923 | $201 | 20.0% |
| $50,000 | $2,190 | $467 | 23.6% |
| $100,000 | $5,032 | $1,021 | 26.9% |
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 $11,808 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 Wisconsin
Wisconsin is a community property state. In community property states, income earned during marriage is generally owned equally by both spouses. This affects QJV eligibility, MFS filing strategies, and retirement account contribution rules.
