Montana’s decision to create a separate property tax rate for homes not used as primary residences has drawn renewed attention as other jurisdictions consider similar approaches to housing affordability. New York City is among the latest to pursue comparable legislation, reflecting a growing national debate over whether tax policy can slow the pricing pressures that have left working residents unable to afford homes in markets they have long called home.
Montana’s Approach
The Montana Legislature passed a measure establishing a distinct tax classification for residential properties whose owners do not use them as permanent residences. The move came after a sustained influx of out-of-state buyers purchasing second homes drove up both sale prices and property tax assessments for full-time Montanans. Projections tied to the legislation suggested that average owner-occupant property taxes could fall roughly 18 percent over the first two years of implementation.
The affordability pressure behind the policy is measurable. In Bozeman, median home prices run approximately seven times the median household income — a ratio that mirrors conditions in New York City and underscores how mountain-West resort and lifestyle markets now rival major metropolitan areas in pricing strain.
New York City’s Proposed Levy
New York City has been weighing its own version of a second-home surcharge since at least 2021. The proposal — sometimes called a “pied-à-terre tax” — would apply to residential properties valued above $5 million that are not occupied as a primary residence. If enacted after state approval, the city estimates it could generate roughly $500 million in the first year alone.
The proposal has drawn pointed criticism from prominent financial figures. JPMorgan Chase chief executive Jamie Dimon publicly criticized Mayor Zohran Mamdani over the plan. Hedge fund billionaire Ken Griffin, commenting to the Financial Times, said the proposal “trigger[ed] the trauma I went through in Chicago,” alluding to his earlier decision to relocate his firm out of Illinois.
A Broader Trend
Montana and New York City are not alone. Rhode Island enacted what has been nicknamed a “Taylor Swift tax” targeting second-home owners, while Hawai’i County set higher property tax rates on non-primary residences. Washington, D.C., imposes elevated rates on high-value properties as well. The cluster of activity suggests that local and state governments across the political spectrum are reaching for similar tools as affordability pressures mount nationwide.
Data from the Atlanta Federal Reserve’s Home Ownership Affordability Monitor indicates that buying a home is now as difficult as it was in 2006, near the peak of the mid-2000s housing bubble. The average household currently approved for a mortgage carries an income roughly double the national median — meaning the typical American family is effectively priced out of the conventional mortgage market.
Policy Context in Montana
Montana’s second-home tax did not emerge in isolation. The state has faced overlapping affordability pressures in recent years, with remote-work migration accelerating demand in communities like Bozeman and Whitefish. Long-term residents and working families have faced rapidly rising assessments even on homes they have owned for years, fueling bipartisan support in the Legislature for relief measures aimed at primary-residence owners.
The tension over housing and residency also intersects with broader debates about state services and family stability. Montana has separately been grappling with child welfare caseloads, with officials looking at resource constraints across multiple social service areas as population and cost pressures have intensified.
Whether second-home taxes deliver sustained relief for owner-occupants or simply add one layer to a complex affordability picture remains an open question. Supporters argue the policies redirect the tax burden toward discretionary property owners rather than full-time residents. Critics contend the levies may dampen investment or prove difficult to administer. Montana’s early implementation will likely be watched closely as New York and other states decide whether to follow a similar path.
