Montana imposes no state estate tax, so federal law under IRC § 2001 is the only estate-level levy that applies. With a permanent federal exemption of $15M per decedent from 2026, after the One Big Beautiful Bill Act (July 2025) repealed the scheduled TCJA sunset, the vast majority of Montana estates clear probate without owing estate tax at any level. Montana's common-law property rules keep each spouse's individually titled assets separate, so how property is titled still determines what passes through probate here. There is no separate inheritance tax, so beneficiaries receive their share without a second state-level deduction at distribution.
IRS Statistics of Income data show 33 federal estate tax returns filed by Montana residents in the most recent available year (filing year 2023), reporting $0.81 billion in combined gross estate value. Net federal estate tax paid totaled $0.10 billion that year. Across the multi-year IRS SOI series above, Montana averages roughly 27 taxable filings per year, with an effective federal rate on reported gross estates of about 5.8%.
Probate itself typically runs 6–12 months in Montana (roughly 9 months on average), with court filing fees of $50–$200. Attorney fees are negotiated rather than statutory, so engagement letters and hourly-vs-flat structures matter more to the total bill. Montana does offer a simplified small-estate track for estates under $100,000, which most families use to bypass full formal probate. Because Montana has adopted the Uniform Probate Code (since 1974), procedures are broadly standardized across counties. As a common-law (separate property) state, Montana treats each spouse's holdings individually unless jointly titled, so titling choices drive what actually enters the probate estate.

Montana adds no state-level death tax, your planning centers on the federal $15M exemption and probate.

No. Montana does not have a state estate tax. Only the federal estate tax applies (a permanent $15M exemption per person from 2026). This makes Montana more favorable for estate planning compared to the 13 states that do impose a state estate tax. Probate attorney fees here are negotiated (hourly or flat) rather than fixed by statute, on top of modest court filing fees.
No. Montana does not impose a state inheritance tax on beneficiaries. Unlike an estate tax (paid by the estate), an inheritance tax is paid by the person receiving the assets. Only six states currently levy this tax. Montana has adopted the Uniform Probate Code (since 1974), which standardizes procedures statewide.
Probate in Montana typically takes 6 to 12 months. Estates under $100,000 may qualify for a simplified small estate procedure, which is significantly faster.
Court filing fees in Montana range from $50 to $200. Attorney fees are usually based on reasonable hourly rates or negotiated flat fees.
Yes. Common probate avoidance strategies in Montana include revocable living trusts, transfer-on-death (TOD) deeds for real estate, payable-on-death (POD) accounts for bank and investment accounts, and joint ownership with right of survivorship. Montana also offers a simplified process for small estates under $100,000.
The TCJA provisions were scheduled to sunset after December 31, 2025, which would have cut the federal exemption from $13,990,000 to roughly $7,000,000 per person. The One Big Beautiful Bill Act (Pub. L. 119-21), signed July 4, 2025, repealed that sunset and set a permanent $15,000,000 per-individual exemption effective January 1, 2026, indexed for inflation. Because Montana has no state estate tax, only the federal exemption applies, and the permanent $15,000,000 threshold means very few Montana estates owe federal estate tax.
