Wisconsin Capital Gains Tax Rate (2026)
Wisconsin capital gains tax overview
Four brackets from 3.5% to 7.65%. Wisconsin taxes capital gains as ordinary income.
Federal + Wisconsin combined rates
Your total capital gains tax bill includes both layers — federal and state. Here is what a Wisconsin investor pays in 2026 for long-term gains:
| Federal Long-Term Rate | Wisconsin State Rate | Combined Rate | Plus NIIT (if applicable) |
|---|---|---|---|
| 0% | 7.65% | 7.65% | 11.4% |
| 15% | 7.65% | 22.6% | 26.5% |
| 20% | 7.65% | 27.6% | 31.5% |
The NIIT (Net Investment Income Tax) adds an extra 3.8% for taxpayers whose MAGI exceeds $200,000 (single) or $250,000 (married filing jointly). It is a federal tax only — Wisconsin does not have an equivalent.
How Wisconsin compares to other states
Wisconsin's top rate of 7.65% places it in the upper-middle tier of state capital gains taxation. For comparison:
- Zero-tax states (FL, TX, NV, etc.): 0% — total with 15% federal = 15%
- Low-rate states (AZ, IN, PA): 2.5–3.1% — total with 15% federal = 17.5–18.1%
- Wisconsin: 7.65% — total with 15% federal = 22.6%
- High-rate states (NY, NJ): 10.75–10.9% — total with 15% federal = ~26%
- California: 13.3% — total with 15% federal = 28.3%
Tax-reduction strategies for Wisconsin residents
With a top state rate of 7.65%, minimizing capital gains tax is particularly important in Wisconsin. Key strategies:
- Hold over 1 year for long-term federal rates (0/15/20%). Wisconsin does not offer a preferential state rate, but federal savings alone are often 7–17%.
- Tax-loss harvesting: Offset your gains with losses realized in the same year. A $20,000 loss offsets $20,000 of gains dollar-for-dollar, saving up to 28% ($5,530) on that $20,000 at top rates.
- 0% bracket planning: In lower-income years (retirement, sabbatical, between jobs), realize gains at the federal 0% rate. You still owe Wisconsin state tax, but eliminating the federal component is significant.
- Donate appreciated stock directly to charity or a donor-advised fund to avoid capital gains tax entirely while generating a charitable deduction for the full fair market value.
- Installment sales: If selling a business or real estate, structuring as an installment sale spreads the gain over multiple years, potentially keeping each year's gain in a lower bracket.
Detailed Wisconsin capital gains tax rules
Tax history and legal basis
Wisconsin taxes capital gains as ordinary income with a progressive system. The top rate is 7.65% on income over $315,310 (single).
Exemptions and special treatment
Wisconsin offers a 30% exclusion on net long-term capital gains from the sale of farm assets (farmland, buildings, equipment). General stock market gains receive no exclusion. Wisconsin also allows a subtraction for certain Wisconsin-based business stock held 5+ years.
Filing requirements
File Form 1 (resident). Wisconsin starts with federal AGI. The state requires estimated payments if owing $200+. Filing deadline is April 15.
Recent changes and legislative updates
Wisconsin's top rate of 7.65% makes it a high-tax state for capital gains. There have been proposals to create a flat tax or reduce the top bracket, but the divided legislature has prevented major changes. The 30% farm capital gains exclusion is particularly important in this agricultural state.
Worked example: $50,000 capital gain in Wisconsin
Here's exactly what a Wisconsin resident would owe on a $50,000 long-term capital gain with $80,000 in other income (single filer, 2026):
| Component | Amount | Notes |
|---|---|---|
| Capital gain | $50,000 | Long-term (held over 1 year) |
| Federal tax (15%) | −$7,500 | Based on $80,000 ordinary income + gain |
| Wisconsin state tax (5.3%) | −$2,650 | Applied to the full gain amount |
| Total tax owed | −$10,150 | Federal + state combined |
| You keep | $39,850 | 79.7% of your gain |
After both federal and Wisconsin state tax, you keep $39,850 of your original $50,000 gain. The effective combined rate is 20.3%.
Frequently asked questions — Wisconsin
Does Wisconsin tax short-term and long-term gains differently?
No — Wisconsin taxes both short-term and long-term capital gains as ordinary income at the same rates as wages. There is no state-level preferential rate for patience. The federal system, however, taxes long-term gains at 0/15/20% vs. up to 37% for short-term — a significant difference that applies regardless of state.
Do I need to file a Wisconsin tax return if I only have capital gains?
If you have capital gains income and meet Wisconsin's filing threshold, you are required to file a Wisconsin state income tax return. The threshold is typically similar to the standard deduction amount — check the WI Department of Revenue for the current year's filing requirements.
What if I moved to Wisconsin mid-year?
If you moved to Wisconsin during the year, you are a part-year resident. Wisconsin generally taxes capital gains realized while you were a Wisconsin resident. Gains realized before you moved may be taxable by your prior state. Keep detailed records of when each sale occurred relative to your move date.
