Divorce money in Wisconsin: property, support, legal fees and whether the state taxes alimony
The money picture for a divorce in Wisconsin: how property gets divided, what Wisconsin calls spousal support and how it is decided, whether one spouse can be made to pay the other’s legal fees while the case is running, and — the part nobody publishes — whether Wisconsin’s own income tax follows the federal rule on alimony.

Does Wisconsin follow the federal alimony rule?
Since 2019, federal law has treated alimony as not deductible by the payer and not taxable to the recipient, for any instrument executed after 31 December 2018. Most people assume every state followed. Most did. Not all.
Wisconsin uses static IRC conformity fixed at December 31, 2017 (Wis. Stat. § 71.01(6)) – a date just 9 days after the TCJA’s December 22, 2017 enactment – so the TCJA’s repeal of IRC § 71 is already baked into the fixed federal code Wisconsin references. The Wisconsin Department of Revenue confirms this directly and explicitly for alimony rather than leaving it to inference from the conformity date alone.
So the federal answer is your answer: post-2018 instruments, no deduction and no inclusion, on either return.
Source: Wisconsin Department of Revenue, Publication 109, ‘Tax Information for Married Persons Filing Separate Returns and Married Persons Who Are Divorced or Separated’ (2025 rev.): ‘Beginning on January 1, 2019, any divorce agreement providing for the payment of alimony no longer has a tax effect on the payor or payee’s tax return… for divorce agreements entered into after December 31, 2018, the payor of the alimony is no longer allowed to claim a deduction for the payment and the payee… is no longer required to include the alimony on their tax return as income. Wisconsin follows these federal changes.’ Pre-2019 agreements are expressly grandfathered with the old deductible/includable treatment, subject to Wisconsin’s marital-property-law apportionment rules. · source
Conformity: static: 31 Dec 2017 (Wis. Stat. § 71.01(6)); DOR guidance confirms conformity to the TCJA alimony rule regardless
Nationally: 36 states follow the federal rule, 9 have no income tax, 4 are decoupled, and 1 — Maine — we could not establish. The full fifty-state table and what each decoupled state does differently.
How property is divided
Wisconsin is an equitable distribution state. That means the court divides marital property fairly, which is not a synonym for equally. What counts as marital rather than separate property is frequently the whole argument.
Upon every judgment of annulment, divorce, or legal separation… the court shall divide the property of the parties… The court shall presume that all property… is to be divided equally between the parties, but may alter this distribution without regard to marital misconduct after considering all of the following [factors]

Maintenance
Wisconsin calls it maintenance. Using the state’s own word matters when you are searching for forms or reading a statute.
There is no guideline calculation. A judge weighs the statutory factors and reaches a number.
This is the norm and it is why alimony is the least predictable figure in a divorce. Two judges can reach different answers on the same facts and both be right. It also means the strength of your evidence about income, earning capacity and the standard of living during the marriage does real work.
the court may grant an order requiring maintenance payments to either party for a limited or indefinite length of time… after considering all of the following [factors]
Source: Wis. Stat. § 767.56(1c)
Child support
Wisconsin uses the percentage of obligor income model — the calculation looks principally at the paying parent’s income.
Whichever model applies, this is the most predictable number in your case — there is a formula and a presumption that its output is correct. Deviating from it takes written findings. Run it early; it is free, and it anchors everything else.
Guideline: Wis. Stat. § 767.511(1) (court determines child support using the percentage standard established by the Department of Children and Families under § 49.22(9)); Wis. Admin. Code DCF 150 (percentage-of-income standard, e.g. 17%-34% of gross income depending on number of children)

Who pays for the lawyers
The court, after considering the financial resources of both parties, may… [o]rder either party to pay a reasonable amount for the cost to the other party of maintaining or responding to an action affecting the family and for attorney fees to either party.
Source: Wis. Stat. § 767.241(1)(a)
Requiring either party to pay for the maintenance of the other party. Maintenance under this paragraph may include the expenses and attorney fees incurred by the other party in bringing or responding to the action affecting the family.
A fee award that only arrives at final judgment is close to worthless to someone who could not afford a lawyer during the case. By then it is over. An interim award is what stops a wealthier spouse winning by attrition.
If you are the lower earner, this is the single most actionable thing on this page. Ask at the first meeting, in these words: “Can we move for an interim award of attorney fees now?” Do not let “we will deal with fees at the end” pass unexamined.
Separately, if custody is contested you may be ordered to pay for a guardian ad litem or a custody evaluator, and the court decides how to split that. What that costs in Wisconsin, and who bears it.
The thing worth knowing about Wisconsin
Wisconsin is a marital-property (community-property-style) state under its Marital Property Act, and its Department of Revenue guidance addresses a nuance unique to that regime: because each spouse already owns a present, undivided one-half interest in marital property income during the marriage, a pre-2019 (grandfathered) alimony payment is deductible to the payor only to the extent the payment exceeds the recipient spouse’s own pre-existing one-half share of marital property income – otherwise the payor is merely transferring control of money the recipient already owned, not making a deductible transfer.
