Montana's Second-Home Tax Rate Hits 1.9%, Outpacing the 2027 Social Security Raise
By Bear Creek Staff, . Bear Creek Capital Network.
Montana's 2026 property-tax overhaul is forcing retirees with second homes to rethink a budget assumption that held for years: that a paid-off cabin is cheap to keep. 24/7 Wall St reported the details, citing the Helena Independent Record on the mechanics of the new law.
What changed
The overhaul, which took effect with 2026 property-tax bills, created a dedicated classification for second homes, short-term rentals and vacant residential lots. Properties in that class carry a flat 1.9% rate applied to assessed market value, producing what Montana calls a "taxable value." Local mill levies, set by counties, school districts and other taxing bodies, are then applied to that taxable value to generate the actual bill. Qualifying primary residences fall into lower, tiered rates instead.
CNBC reported separately that Montana's Department of Revenue projected the changes would lift second-home tax bills by an average of 68%. CNBC also noted the pattern is spreading, describing similar moves in other states under the label of a "Taylor Swift Tax" on vacation properties owned by wealthier households.
Why the Social Security raise may not close the gap
The Social Security Administration confirmed on October 14, 2026 that the 2027 cost-of-living adjustment, which measures how much benefits rise to keep pace with inflation, will be 3.6%. That is the largest annual increase since the 8.7% adjustment in 2023, and it takes effect in January 2027.
On a $2,000 monthly benefit, 3.6% works out to $72 more per month, or $864 over a full year, before any Medicare premium adjustment. The 24/7 Wall St piece uses a hypothetical illustration to show the problem: a $1,500 annual property-tax increase on a cabin would exceed that raise by $636. The first property-tax payment under the new classification is due in November, before the larger Social Security checks begin arriving.
The structural mismatch is the real issue. A cost-of-living adjustment is tied to a national inflation index and moves as a fixed percentage of whatever benefit a retiree already receives. A second home's carrying costs, taxes, insurance, maintenance and utilities, follow local assessors and local markets, which can move faster and in a different direction than any national average.
What owners should check
The piece walks through four questions worth working through before deciding whether to keep or sell a second property. Could the cabin qualify as a primary residence, which requires living there at least seven months a year and giving up the primary-residence classification on the other property? Does the owner qualify for Montana's assistance programs for lower-income or older homeowners, most of which cover only a primary residence? What does the property cost in total once insurance, utilities, maintenance and travel are added to the tax bill? And would renting it out help, keeping in mind that short-term rentals carry the same 1.9% rate, while a qualifying long-term rental may get a lower rate but could also push more Social Security income into taxable territory?
The practical starting point is comparing the 2026 property-tax bill against last year's to measure the actual increase, then adding the cabin's other annual costs and setting that total against available income.
The broader implication for retirees holding second properties anywhere is that a fixed-income raise calibrated to national inflation offers limited protection against locally driven cost increases. Montana is one state; CNBC's reporting suggests the policy direction is not unique to it. Owners in other states with similar legislation in progress face the same arithmetic problem, and the gap between a national cost-of-living adjustment and a local tax bill is unlikely to close on its own.
