Working Military Retirement Exemption
Montana does not exempt all military retirement pay. A resident may subtract the lesser of 50 percent of military retirement income or Montana-source wages, business income, or farm income. The Department of Revenue limits the claim to five consecutive years. You qualify if you became a resident after June 30, 2023, or you were a resident before the retired pay started and you stayed a resident. Survivor Benefit Plan beneficiaries can exempt up to 50 percent of those benefits. Claim it on Form WMRE with Form 2. Senate Bill 93 removed the December 31, 2033 end date for later tax years. The five-year limit is still in the Department of Revenue instructions. https://revenue.mt.gov/taxes/individual-income-tax/working-military-retirement-exemption
