Wisconsin taxes capital gains as ordinary income but offers a partial exclusion for long-term capital gains that can significantly reduce the effective rate. This exclusion, combined with Wisconsin’s graduated rate structure, creates a more nuanced capital gains tax system than many states. Understanding the exclusion rules and rate brackets is essential for Wisconsin investors and business owners looking to minimize their tax liability.
Wisconsin Capital Gains Tax Rates
Wisconsin’s standard income tax brackets apply to capital gains:
| Tax Rate | Single Filer Income | Married Filing Jointly Income |
|---|---|---|
| ~3.5% | $0 - ~$14,320 | $0 - ~$19,090 |
| ~4.4% | ~$14,321 - ~$28,640 | ~$19,091 - ~$38,190 |
| ~5.3% | ~$28,641 - ~$315,310 | ~$38,191 - ~$420,420 |
| ~7.65% | Over ~$315,310 | Over ~$420,420 |
Wisconsin’s Long-Term Capital Gains Exclusion
Wisconsin allows taxpayers to exclude ~30% of net long-term capital gains from Wisconsin taxable income. This exclusion effectively reduces the tax rate on long-term gains:
| Bracket | Standard Rate | Effective Rate (After ~30% Exclusion) |
|---|---|---|
| ~3.5% | ~3.5% | ~2.45% |
| ~4.4% | ~4.4% | ~3.08% |
| ~5.3% | ~5.3% | ~3.71% |
| ~7.65% | ~7.65% | ~5.36% |
The ~30% exclusion reduces the top effective rate on long-term capital gains from ~7.65% to approximately ~5.36%.
Combined Federal and Wisconsin Capital Gains Tax
| Scenario | Federal Rate | WI Effective Rate | Combined Rate |
|---|---|---|---|
| Long-term, ~0% federal bracket | ~0% | ~2.45-3.08% | ~2.45-3.08% |
| Long-term, ~15% federal bracket | ~15% | ~3.71-5.36% | ~18.71-20.36% |
| Long-term, ~20% federal bracket | ~20% | ~5.36% | ~25.36% |
| Long-term + NIIT | ~23.8% | ~5.36% | ~29.16% |
| Short-term (no exclusion) | Up to ~37% | ~7.65% | Up to ~44.65% |
How Wisconsin’s Capital Gains Exclusion Works
Qualifying for the Exclusion
The ~30% exclusion applies to net long-term capital gains from assets held for more than ~1 year. Key details:
| Factor | Detail |
|---|---|
| Exclusion percentage | ~30% of net long-term capital gains |
| Holding period | Must be held longer than ~1 year |
| Short-term gains | No exclusion available |
| Applies to | Stocks, bonds, mutual funds, real estate, business assets |
| Farm assets | ~60% exclusion (enhanced) |
| Collectibles | Standard ~30% exclusion applies |
Enhanced Farm Asset Exclusion
Wisconsin provides an enhanced ~60% exclusion for capital gains from the sale of farm assets, including farm real estate, farm machinery, and livestock held for draft, breeding, or dairy purposes. This makes the effective rate on farm asset gains even lower:
- Top rate: ~7.65%
- After ~60% exclusion: ~3.06%
Example Calculation
A Wisconsin resident with ~$100,000 in long-term capital gains (taxable income in the ~5.3% bracket):
- Gross long-term gain: ~$100,000
- Exclusion (~30%): ~$30,000
- Taxable gain: ~$70,000
- Wisconsin tax: ~$70,000 x ~5.3% = ~$3,710
- Effective rate: ~3.71% (vs. ~5.3% without exclusion)
- Tax savings from exclusion: ~$1,590
Wisconsin vs. Neighboring States
| State | Top Capital Gains Rate | Exclusion Available? | Effective Top Rate |
|---|---|---|---|
| Wisconsin | ~7.65% | ~30% exclusion | ~5.36% |
| Minnesota | ~9.85% | None (small biz exception) | ~9.85% |
| Iowa | ~5.7% | None | ~5.7% |
| Illinois | ~4.95% (flat) | None | ~4.95% |
| Michigan | ~4.25% (flat) | None | ~4.25% |
After the exclusion, Wisconsin’s effective rate of ~5.36% is competitive with Iowa and Illinois. Without the exclusion, Wisconsin’s ~7.65% rate would be the second-highest in the region after Minnesota.

Tips for Managing Wisconsin Capital Gains Tax
-
Always hold for more than one year. The ~30% exclusion only applies to long-term gains. Selling before the ~1-year mark means paying the full rate and losing both the federal preferential rate and the Wisconsin exclusion. On a ~$100,000 gain, this could cost approximately ~$15,000 or more in combined tax.
-
Maximize the exclusion. Ensure all qualifying gains are properly reported as long-term on your return. Review your brokerage statements for any misclassified transactions. The exclusion is claimed on Schedule WD of your Wisconsin return. See our federal income tax guide.
-
Use tax-loss harvesting. Losses offset gains before the exclusion applies. Harvest short-term losses to offset short-term gains (which get no exclusion) and let long-term gains benefit from the ~30% exclusion.
-
Farm asset planning. If you are selling farm assets, the enhanced ~60% exclusion cuts the effective rate nearly in half. Plan the timing and structure of farm sales to maximize this benefit. Consult our self-employment tax guide for related strategies.
-
Consider installment sales. Spreading a large gain over multiple years can keep your income in lower brackets. Combined with the ~30% exclusion, installment treatment on long-term gains provides the best possible rate.
-
Maximize tax-advantaged accounts. Gains in 401(k), IRA, and Roth accounts are not subject to Wisconsin capital gains tax. Maximize contributions to shield growth from both federal and state taxes.
-
Make timely estimated payments. Wisconsin requires estimated tax payments if you expect to owe ~$500 or more. Large capital gains that are not covered by withholding require estimated payments to avoid underpayment penalties. Use our tax bracket calculator to model your liability.
