Common Mistakes to Avoid
- Not applying at all. The homestead exemption is not automatic in most cases. Nobody will give you the savings unless you file the paperwork. Millions of homeowners miss out because they never apply.
- Missing the deadline. Deadlines in Montana are firm. If you miss March 15 for PTAP. April 15 for property tax freeze., you are stuck paying full taxes for another year.
- Not claiming additional exemptions. Many homeowners qualify for senior, veteran, or disability exemptions on top of the basic homestead exemption. Check if you can stack benefits for bigger savings.
- Forgetting to reapply after moving. Your exemption does not follow you to a new home. When you buy a new property, file a new application.
- Claiming on a non-primary residence. This is fraud. Only claim the exemption on the home where you actually live.
Can You Combine the Homestead Exemption With a Property Tax Appeal?
Yes, and you should consider it. The homestead exemption reduces your taxable value by a fixed amount. A property tax appeal can reduce your assessed value if your home is over-valued by the assessor. These are two different things, and they work together.
If your home is assessed at $350,000 but comparable sales show it is worth $310,000, a successful appeal drops your assessed value by $40,000. Add a homestead exemption on top of that, and you are looking at much bigger savings than either one alone.
Many Montana homeowners save more from a property tax appeal than from their homestead exemption. It is worth checking whether your assessment is too high.
