The rest of what we have written about Idaho. Every figure is quoted from Idaho’s own statute or its courts’ own published schedule, and carries the date we last checked it.
Dividing property and money in a Idaho divorce
The money picture for a divorce in Idaho: how property gets divided, what Idaho 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 Idaho’s own income tax follows the federal rule on alimony.

Every claim is traced to Idaho’s own statute, court rule or revenue department, quoted where the wording carries the meaning. Where we could not verify something, the page says so instead of filling the space. Information, not legal advice — and tax questions in particular need a professional in your state.

Does Idaho 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.
Idaho defines ‘Internal Revenue Code’ for state income tax purposes as the IRC in effect on a fixed date that the legislature updates every year (a de facto rolling conformity via annual re-enactment). The current statute sets the date at January 1, 2026, long after the TCJA’s alimony changes took effect, so Idaho follows the federal non-deductible/non-taxable treatment for post-2018 instruments.
So the federal answer is your answer: post-2018 instruments, no deduction and no inclusion, on either return.

Conformity: static, updated annually by the legislature: currently 1 Jan 2026 (post-TCJA)
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
Idaho is a community property state. Property acquired during the marriage is generally owned by both of you, and the starting point is a division of that community estate rather than an open-ended fairness inquiry.
The community property must be assigned by the court in such proportions as the court … deems just … Unless there are compelling reasons otherwise, there shall be a substantially equal division in value

Maintenance
Idaho 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 a maintenance order if it finds that the spouse seeking maintenance: (a) Lacks sufficient property to provide for his or her reasonable needs; and (b) Is unable to support himself or herself through employment

Who pays for the lawyers
the court may from time to time … order a party to pay a reasonable amount for the cost to the other party of maintaining or defending any proceeding under this act and for attorney’s fees, including sums for legal services rendered and costs incurred prior to the commencement of the proceeding or after entry of judgment.
Source: Idaho Code § 32-704(3)
While an action for divorce is pending, the court may, in its discretion, on the motion of either party … order the payment of temporary maintenance of either spouse by the other … in amounts and on terms just and proper under the circumstances (Idaho Code § 32-704(1)); fee awards under subsection (3) expressly include ‘costs incurred prior to the commencement of the proceeding’
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 Idaho, and who bears it.
The thing worth knowing about Idaho
Idaho’s community-property division statute lists marital fault nowhere among the factors a court may weigh (Idaho Code § 32-712(1)(b)) – division is fault-neutral, with a statutory presumption of substantially equal division ‘unless there are compelling reasons otherwise.’
What we could not verify
For Idaho, we could not confirm the following from a primary source. We would rather print the gap than fill it:
