In municipalities that have adopted a vacant home tax, filing an annual vacant home tax declaration isn't optional paperwork reserved for owners of empty houses — it's typically a requirement for essentially every residential property owner, whether or not the home is occupied. Missing it is one of the most common (and most avoidable) ways homeowners end up disputing a tax bill they don't think they owe.
This article walks through what the declaration process generally looks like, who has to file, and what happens if you don't.
Who Has to File
In municipalities with a vacant home tax bylaw, the declaration requirement generally applies broadly across residential property owners — not just to people who suspect their property might be considered vacant. A homeowner who lives in their house full-time, and a landlord with a long-term tenant, both typically still need to confirm that occupancy status through the declaration process.
Exact scope varies by municipality — some bylaws distinguish between property types or exempt certain categories from the filing requirement itself, not just from the tax. Always confirm the current rules with your specific city.
What the Declaration Generally Asks
Most vacant home tax declarations ask the owner to confirm the property's occupancy status over a defined reporting period (typically the prior calendar year), and to select from a set of standard categories, such as:
- Occupied by the owner as a principal residence
- Occupied by a tenant under a long-term arrangement
- Occupied by a permitted occupant (such as a family member)
- Unoccupied, but the subject of a recognized exemption
- Unoccupied and not subject to any exemption
The exact categories and wording differ by municipality, and some cities require supporting information depending on which category you select.
The General Filing Process
- Watch for notice from your municipality. Cities that run these programs typically send a reminder to the property owner on file, but the obligation to file exists independent of whether you actually receive that notice.
- Confirm the reporting period. The declaration usually covers a defined past period, not the current date you're filing — make sure you're answering for the right timeframe.
- Select the accurate occupancy category. Choose the category that genuinely reflects how the property was used during the reporting period, not how it's used today if that's changed.
- Keep supporting records. If you're claiming an exemption or a particular occupancy category, retain documentation (leases, utility bills, correspondence) that could support your declaration if the municipality asks questions later.
- File before the municipality's deadline. Deadlines are set by each municipality and can shift year to year — confirm the current date directly with your city rather than relying on last year's date.
- Retain your confirmation. Keep proof that you filed, in case a dispute arises later about whether or when you submitted the declaration.
What Happens If You Miss the Deadline
Missing the declaration deadline is treated seriously in most of these programs. A common approach among municipalities that run a vacant home tax is to treat a missed or late declaration as a default finding of vacancy — meaning the tax can apply even to a home that was, in fact, fully occupied all year, simply because the paperwork wasn't filed on time. Some municipalities also apply a separate fee for a late or missed declaration, on top of any tax owed.
If you discover you've missed a filing, most municipalities provide some process to dispute or correct a default assessment, but the process, evidence required, and time limits to act vary by city — don't assume you can simply explain the situation informally after the fact.
A Quick Checklist for Filing Season
- [ ] Confirm whether your municipality runs a vacant home tax program at all
- [ ] Note the current filing deadline for your city (it can move year to year)
- [ ] Identify which occupancy category accurately describes your property for the reporting period
- [ ] Gather supporting documentation if you're claiming an exemption
- [ ] File through your municipality's official portal or process
- [ ] Save your confirmation of submission
- [ ] Set a reminder for next year's filing period
Frequently asked questions
I own multiple properties in the same city — do I need to file separately for each?
Generally yes. The declaration typically applies on a per-property basis, so owning several units or homes in a participating municipality usually means a separate declaration for each one, not a single combined filing.
What if I sold the property partway through the reporting period?
Ownership changes during the reporting year commonly raise their own rules about who is responsible for the declaration and for what portion of the period — this is worth confirming directly with the municipality or your lawyer as part of the sale, rather than assuming it sorts itself out automatically.
Can I dispute a default vacancy assessment after the fact?
Most municipalities offer some form of review or appeal process for a default assessment, but there are typically time limits and documentation requirements. Act promptly once you realize a filing was missed rather than waiting.
Does filing the declaration cost anything?
The declaration itself is generally a reporting requirement, separate from any tax that might become payable depending on your answers. Confirm with your specific municipality whether any administrative fee applies to the filing process itself.
