A Clark County dairy, an Arlington cash-grain farm, a Wood County cranberry marsh, a northern timber tract, and a Fox River machine shop can close in the same month and owe different Wisconsin tax on the same federal gain. Wisconsin runs capital gain through ordinary brackets, then subtracts part of the long-term piece. Farm assets get a larger subtraction. A sale to a close relative can remove still more.
This page is that Wisconsin layer. How to allocate a farm price, settle equipment recapture, and put the land on a schedule is in the farmland sale guide and the farmland 1031 comparison.
For 2026, full-year residents use four brackets. A joint return pays 3.5% to $20,150 of taxable income, 4.4% to $69,260, 5.3% to $443,630, and 7.65% above $443,630. Single filers, heads of household, estates, and trusts hit 7.65% above $332,720. Those thresholds are in the Department of Revenue's 2026 estimated-tax instructions. There is no separate long-term rate. The preference is a subtraction.
On assets held more than one year, and on assets acquired from a decedent, Wisconsin generally subtracts 30% of net capital gain. Farm assets get 60% instead. Publication 103 (January 2026) and Wis. Stat. § 71.05(6)(b)9. and 9m. are the authorities. Individuals compute it on Schedule WD. Farm assets means livestock, farm equipment, farm real property, and farm depreciable property. Gains and losses are netted first. Ordinary income, including depreciation recapture, is left out, as is a lottery prize treated as capital gain.
Read 60% as the whole exclusion for qualifying farm gain, not 30% plus another 60%. Forty percent of that gain stays in Wisconsin income and then runs through the brackets. A $2 million long-term gain on farmland is an $800,000 Wisconsin gain before other adjustments, and that $800,000 can still reach 7.65%.
Under § 71.05(6)(b)25., long-term gain on business assets or assets used in farming, sold to a relative by blood, marriage, or adoption within the third degree, may be subtracted to the extent the 30% exclusion did not already remove it. Report it on Schedule SB, or Schedule M for Form 1NPR, not inside Schedule WD. Ordinary income does not qualify. The statute also reaches certain farm-entity interests: a qualifying farm corporation or farm trust, and, after 2023, a farm partnership or LLC with 15 or fewer natural-person members. Publicly traded stock does not qualify.
Prepare Schedule WD and Schedule SB together. The family subtraction cross-references the 30% rule, not a clean stack on the 60% farm exclusion, so do not claim a 100% wipeout. If the relative resells within two years, IRC §453(e) can accelerate the remaining federal gain. Basis on inherited acres is covered on the inherited-farmland page.
Wisconsin starts from federal adjusted gross income, so gain on Form 6252 generally appears and is then modified on Schedule WD. Publication 103 also says you may elect installment treatment for Wisconsin differently than you do federally, with a pro forma federal return or Schedule I. That choice belongs with the preparer who signs the return.
Nonresidents report Wisconsin-source gain, including gain from land, buildings, and machinery in Wisconsin, so installment payments on a Wisconsin farm generally stay on Form 1NPR after a move. Publication 103 runs the other direction: an installment sale of out-of-state real estate made while you were a nonresident is treated as recognized before a later move into Wisconsin. Moving in does not import that gain. Moving out does not export gain on Wisconsin dirt.
Nonresidents and part-year residents also prorate bracket widths by Wisconsin income divided by federal adjusted gross income. The 2026 estimated-tax instructions show a single filer with a 20% ratio who does not get the full room before 7.65%. A large portfolio in a no-tax state plus a Wisconsin farm installment can face a higher Wisconsin rate than the resident table suggests.
Schedule CG can defer gain reinvested in a qualified Wisconsin business within 180 days, and Schedule QI can exclude gain on a qualified investment held five years. Those rules are about the investment you buy, not an automatic pass for the goodwill of the company you are selling.
A married couple farming in Dodge County sells the land. The contract price allocable to the land is $2.4 million and the basis is $400,000, so long-term gain is $2 million. Recapture on machinery, grain systems, and tile is ordinary income in the year of sale and is not in the table. The land is farm real property, so the subtraction is 60% and $800,000 is included.
Assumptions, and they are assumptions. Joint return. Other Wisconsin taxable income is $80,000, already in the 5.3% bracket. Federal taxable income before this gain is $150,000, above the 2026 joint 0% long-term threshold of $98,900 in Rev. Proc. 2025-32. Other MAGI is already over the $250,000 net-investment-income-tax threshold, so the 3.8% tax applies to the whole gain either way. The installment case recognizes one-tenth of the gain each year for ten years. It is not a level annuity, which would include ordinary interest. No Wisconsin credits. Figures are estimates.
| Lump sum | Ten years, total | |
|---|---|---|
| Long-term gain recognized | $2,000,000 | $2,000,000 |
| 60% farm subtraction | $1,200,000 | $1,200,000 |
| Gain included in Wisconsin income | $800,000 | $800,000 |
| Estimated Wisconsin tax on that gain | $52,655 | $42,400 |
| Estimated federal long-term capital gains tax | $376,815 | $300,000 |
| Estimated net investment income tax | $76,000 | $76,000 |
| Combined estimate | $505,470 | $418,400 |
Wisconsin tax falls by about $10,300 because the lump-sum year takes included income from $80,000 to $880,000, and everything above $443,630 is taxed at 7.65%. Each installment year includes $80,000 of gain. Stacked on $80,000 of other income, taxable income is $160,000, still inside the 5.3% bracket. Ten years at about $4,240 is $42,400. The exclusion percentage did not improve. The bracket on the included slice did.
Federal tax falls by about $76,800. In the lump-sum year, $463,700 of the gain is taxed at 15%, the room from $150,000 up to the $613,700 joint threshold, and $1,536,300 is taxed at 20%. Each installment year recognizes $200,000. Added to $150,000, taxable income stays under $613,700, so the gain stays at 15%. The 3.8% tax is unchanged under the assumption that every year is already over the threshold.
Nothing here is a promised savings figure. A different basis, more recapture, a child-buyer who qualifies for the Schedule SB subtraction, or a move that compresses the nonresident brackets will rewrite the table. On a Wisconsin farm sale the 60% subtraction does the heavy state work. Installment recognition is what keeps the remaining 40%, and the federal gain, out of one extraordinary year.
A Fox Valley manufacturer or a Milwaukee practice gets the 30% long-term subtraction, not the 60% farm rule. The related-person subtraction can still apply. Goodwill held more than a year is the usual piece that can be scheduled. Equipment recapture under IRC §1245 is ordinary income in the year of sale. Allocation is in the business-sale overview and the §453 explainer.
IRC §453A charges interest on deferred tax when the sales price exceeds $150,000 and installment obligations arising in the year and outstanding at year-end exceed $5 million of face amount. Property used or produced in the farming business, within §2032A(e)(4) or (5), is excepted. A cash-rent landlord should not assume the exception applies. The §453A calculator sketches the federal charge. It is not a Wisconsin return.
Iowa can exclude farmland gain for a qualifying retired farmer. Illinois has no percentage exclusion and an estate tax that reaches farm estates early. Minnesota pairs a high rate with a surtax and a carve-out for certain agricultural land. Wisconsin pairs a percentage exclusion and a kinship subtraction with a 7.65% bracket that installment recognition can sometimes miss. Have a Wisconsin CPA read the agreement and the depreciation schedule before the deal is documented.
Not usually. Wisconsin's top rate on taxable income over $443,630 for a joint return in 2026 is 7.65%, but individuals generally subtract 30% of net long-term capital gain. Farm assets get a 60% subtraction instead. Amounts treated as ordinary income, including depreciation recapture, are not eligible for either subtraction.
Wisconsin statute defines farm assets as livestock, farm equipment, farm real property, and farm depreciable property. The asset must be held more than one year, or acquired from a decedent. The subtraction is claimed on Schedule WD. It does not cover gain that federal law treats as ordinary income.
It may. Long-term gain on business or farm assets sold to a relative within the third degree can be subtracted on Schedule SB to the extent the 30% exclusion did not already remove it. Recapture does not qualify, and a resale within two years can accelerate federal gain. Coordinate Schedule WD and Schedule SB so the same dollar is not subtracted twice.
Yes. Gain from Wisconsin land, buildings, and machinery stays Wisconsin-source, including installment gain after you leave. An out-of-state installment sale you made as a nonresident stays out of Wisconsin income if you later move in. Nonresidents also prorate bracket widths by Wisconsin income divided by federal AGI.
Both can move. The exclusion percentages do not rise if you spread the gain. Spreading can keep included gain out of the 7.65% bracket, and on a large farm sale the bigger change is often federal, from the 15% bracket into 20%. The table is an estimate, not your return.
Farm property used in the farming business is outside the section 453A interest charge. A cash-rent landlord should not assume the exception applies. A non-farm sale can face the charge when obligations arising in the year and outstanding at year-end exceed $5 million of face amount and the sales price exceeds $150,000.
