Idaho Divorce Property Division: The Complete 2026 Guide

Idaho is a community property state. Under §32-712, community property is divided "substantially equal in value" unless compelling reasons exist for deviation.

Deviation factors include: (1) duration of marriage; (2) antenuptial agreement; (3) age, health, occupation, income, skills, employability; (4) liabilities. Homestead special provisions may also apply.

Separate property under §32-906 includes pre-marital assets, gifts, and inheritances. These belong to the original owner and are not divided.

Idaho Code §32-705 provides 7 statutory factors for maintenance. There is no formula and no statutory cap on amount or duration.

The 7 factors: (1) financial resources of requesting spouse; (2) time needed for education/training; (3) duration of marriage; (4) age, physical and emotional condition; (5) ability of paying spouse to meet own needs; (6) tax consequences; (7) fault of either party.

Fault is a statutory factor — this is significant. Unlike many states that exclude fault from financial determinations, Idaho explicitly considers it in maintenance. There is no duration guideline — amount and length are entirely within the court's discretion.

Idaho child support follows IRFLP Rule 120 (updated July 1, 2025). Idaho uses an income shares model based on combined ANNUAL Guidelines Income with a marginal-rate schedule that works like tax brackets.

Key features: the schedule tops out at $440,000 combined annual income — above that, support is discretionary, not capped. Minimum: $50/child/month. For one child, the rate is 18% of the first $10,000 of combined annual income, with the marginal percentage declining in higher brackets (down to ~5% at the top).

6-week residency is required (§32-701). There is a 21-day waiting period after filing.

No-fault ground: irreconcilable differences. Fault grounds are also available, and fault is considered in maintenance under §32-705 factor 7.

Idaho has a flat 5.3% state income tax (HB 40, March 2025). This simplifies tax planning during divorce — both parties know exactly what rate applies regardless of income level.
