An empty property tax is a charge some cities impose on owners who leave a residential unit unoccupied beyond a set number of days each year, and depending on the jurisdiction it takes the form of either a flat annual fee per vacant unit or a percentage of the property’s assessed value. Only a small number of U.S. cities have adopted these taxes, mostly in high-cost housing markets along the West Coast and in Washington, D.C. If your property falls under one of these ordinances, the bill can run into the thousands of dollars a year on top of your regular property taxes, and missing the annual paperwork can trigger the full charge automatically even when the home was occupied.
What Counts as Vacant
The core question is whether someone lived in the property for enough of the year. Most jurisdictions draw the line at 182 days: a home unoccupied for more than that in a calendar year gets classified as vacant. Some cities use a much shorter window, with at least one requiring only 50 days of use to avoid the designation.
Occupancy counts if the owner lives in the home as a primary residence or a tenant occupies it under a lease. Investment properties qualify as long as they’re rented out for enough of the year to clear the threshold. A unit that sits empty for a few months between tenants usually won’t trigger the tax; one that stays listed and unleased for seven or eight months likely will.
Short-term rentals are a gray area. Some cities count nights booked through platforms like Airbnb toward the occupancy threshold. Others exclude short-term stays entirely and require a lease of 30 days or longer. Check your city’s rule before assuming Airbnb bookings protect you.
How Much You’ll Pay
Empty property taxes generally follow one of two models. The first is a flat annual fee per vacant unit, typically ranging from $3,000 to $6,000 per year, with higher amounts in the second and subsequent years of vacancy. Some cities double the fee after year one to escalate pressure on owners to fill the unit.
The second model applies a percentage rate to the property’s assessed value, running roughly 1% to 5%. A 3% rate on a home assessed at $500,000 comes to a $15,000 annual charge on top of regular property taxes. In cities that use this approach, the vacancy rate on an empty home can be five to ten times higher than the standard residential rate.
The vacancy tax is usually billed separately from regular property taxes, and payment deadlines often fall in the first half of the year following the vacancy determination.
Exemptions You Can Claim
Every jurisdiction carves out exceptions for situations where leaving a home empty is beyond the owner’s control. The categories that show up consistently:
- Owner’s death. When a sole-occupant owner dies, the property is typically exempt during probate. Some cities cap this at two years or the duration of probate, whichever is longer.
- Active renovation. Properties undergoing major permitted work that makes them uninhabitable generally qualify. Expect to show that permits are on file and work is progressing. Stalling to avoid the tax won’t hold up under audit.
- Medical or long-term care. If the owner or primary resident moves into a hospital, nursing home, or assisted-living facility, the property is usually exempt for one to two years from the date of admission.
- Court orders. When a court order prevents you from occupying or renting a property during litigation, divorce, or similar disputes, most jurisdictions grant relief for the duration of the order.
- Ownership transfer. New buyers who acquire a property partway through the tax year generally aren’t penalized for the prior owner’s vacancy.
- Natural disaster. Homes rendered uninhabitable by fire, flood, earthquake, or other disasters are exempt while repairs are underway.
Each exemption requires documentation. Cities don’t take your word for it. Expect to submit permits, medical records, court filings, or probate documents alongside your vacancy declaration.
Protections During Military Deployment
Federal law adds a layer of protection for servicemembers whose properties sit empty during deployment. Under the Servicemembers Civil Relief Act, an active-duty servicemember can ask a court to stay enforcement of a tax or assessment, including a vacancy tax, if military service materially affected their ability to pay. The protection runs through the period of service and for 180 days after release from active duty. The SCRA also caps the interest rate on unpaid taxes at 6% per year while protections are in effect, and it blocks the forced sale of a servicemember’s property for unpaid taxes without a court order.
These federal protections apply regardless of which city imposes the tax. If you’re deployed and receive a vacancy bill, you still need to take affirmative steps: file a request with the court and show that your service is the reason the property sits empty. The protection delays collection and limits penalties, it doesn’t erase the tax.
Filing Your Annual Vacancy Declaration
Cities with vacancy taxes require an annual declaration confirming whether each residential unit was occupied for the minimum number of days. Even if your property was fully occupied all year, you typically still have to file. This is the single most expensive place to slip up. Most jurisdictions treat a missing declaration as an admission that the property is vacant and assess the tax at the full rate automatically.
The declaration is usually filed through an online portal on the city’s website or by mailing a paper form. You’ll need the parcel identification number or tax roll number from your regular property tax bill, along with personal ID to verify ownership.
Build your occupancy records throughout the year rather than scrambling at filing time. Useful documentation includes utility bills showing consistent water, electricity, or gas usage; a signed lease with dates; a government-issued ID listing the property address; voter registration records; and vehicle registration tied to the address. Overlap between these records strengthens your position if the city audits you.
Penalties for Missing or Falsifying
Enforcement combines self-reporting through the declaration with random audits and investigations of suspicious filings. Cities cross-reference utility data, postal records, and other public information to flag properties that appear unoccupied despite an owner’s claim otherwise.
Penalties follow a general pattern. Missing the declaration deadline triggers automatic classification as vacant plus a fine, which in some cities starts at $250 for the late filing on top of the full vacancy tax. Late payment of the tax itself typically adds a percentage penalty plus monthly interest.
Filing a false declaration is a different order of consequence. At least one jurisdiction imposes fines of up to $10,000 per day for a continuing false-declaration offense, in addition to the back taxes owed. An honest owner who misses a deadline can usually resolve the issue by filing late and paying the penalty. An owner caught fabricating lease agreements or utility records faces fines that can dwarf the original tax bill.
Appealing a Vacant Classification
If your property is classified as vacant and you believe the designation is wrong, you can appeal. The process typically involves filing a formal protest with the city’s tax office or an independent review board within a set window after the assessment, often 30 to 90 days.
A successful appeal usually requires documentary evidence that the property was occupied for the minimum number of days. Bring utility records, lease agreements, and any other proof of occupancy to the hearing. If the vacancy resulted from an exempt circumstance like renovation or medical care, bring the supporting permits or medical records. The burden of proof falls on you as the owner, not on the city. Assessors start from the presumption that their classification is correct.
If the initial appeal is denied, most jurisdictions allow a further appeal to a higher administrative body or to court. Consulting a property tax attorney before the first hearing is worth the cost when the bill is significant, because the rules around evidence and deadlines are strict and a missed procedural step can forfeit your right to challenge the assessment.
The Insurance Problem Owners Miss
The vacancy tax isn’t the only financial risk of leaving a home empty. Standard homeowners policies typically include a vacancy clause that limits or eliminates coverage once a property has been unoccupied for 60 or more consecutive days. After that window closes, your insurer can deny claims for vandalism, water damage, theft, and other losses that occurred while the home sat empty.
You can be paying premiums on time every month and still get a claim denied because the property was vacant when the damage happened. If you know a home will be empty for an extended period, contact your insurer before the vacancy starts. A separate vacant-home policy costs more than standard coverage but actually pays out when something goes wrong. Finding out after a burst pipe or break-in that your policy won’t cover the loss is far more expensive.
