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. Informal guideline: ~1 year of maintenance per 3 years of marriage.

Idaho child support follows IRFLP Rule 120/126 (updated July 1, 2025). Idaho uses an income shares model based on GROSS monthly income.

Key features: $440,000 combined annual income cap. Minimum: $50/child/month. Approximate percentages: 1 child ~18%, 2 ~27%, 3 ~32%, 4 ~36%, 5 ~40%.

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.
