Property tax is a recurring tax that local governments charge owners of real estate, based on the assessed value of the property. It funds services like schools, roads, and emergency response. Rates and assessment methods vary widely by state, county, and city, making it one of the most location-dependent costs of owning a home.
How does property tax work?
Property tax is generally calculated by multiplying your property's assessed value by a local tax rate, often called a millage rate. A local assessor determines the assessed value, which may or may not match what the home would sell for today, and the taxing authorities set the rate each year based on their budgets.
The main moving parts
- Assessed value: the value the local assessor places on your property, sometimes a fraction of market value
- Tax rate: the millage or percentage set by the county, city, school district, and other bodies
- Exemptions: reductions such as homestead exemptions that can lower the taxable value for qualifying owners
- Reassessment: periodic updates to assessed value that can raise or lower your bill over time
Many homeowners never pay the tax directly to the county. If you have a mortgage, the lender often collects a share of the annual tax with each monthly payment and holds it in an escrow account, then pays the bill on your behalf when it comes due. Owners without a mortgage typically pay the county directly, usually once or twice a year.
Because the tax is tied to value, a rising market and periodic reassessments can push your bill up even if nothing about the house changes. Strong local appreciation is good for your equity but can also mean a higher tax over time.
Property tax vs. other ongoing ownership costs
Property tax is one of several recurring costs of ownership, and it is easy to confuse with others. Unlike HOA fees, which go to a private homeowners association for community upkeep, property tax is a government charge that funds public services. And unlike your one-time closing costs, it recurs every year for as long as you own the home.
It also differs from insurance and maintenance. Insurance protects against loss, maintenance keeps the home functional, and property tax is a legal obligation to the local government that does not go away when the mortgage is paid off. Falling behind on it can eventually lead to a tax lien against the property.
Pros | Cons |
|---|---|
Funds local services that support neighborhood quality and home values | Recurs every year and continues after the mortgage is paid off |
Often bundled into your mortgage escrow, so it is paid automatically | Can rise with reassessments even without any improvement to the home |
Exemptions and appeals can reduce the bill for eligible owners | Unpaid taxes can result in liens or, ultimately, loss of the property |
Why it matters for diaspora owners
If you own a US home from abroad, property tax is a standing obligation you have to fund on schedule even while you are thousands of miles away. Missing payments can trigger penalties, interest, and liens, so many overseas owners rely on lender escrow or a property manager to make sure the bill is always paid on time.
Property tax also shapes the economics of a rental. It is a carrying cost that eats into your net yield, so factor it in alongside insurance and management fees when you estimate returns or compare it against your cap rate target.
For owners funding these bills from abroad, moving money in reliably matters as much as moving proceeds out. Dara is built to help diaspora owners send funds across borders for exactly these recurring obligations, so a due date in the US does not become a penalty because your money was slow to arrive. Check your local assessor's schedule and any exemptions you may qualify for, since rules vary by jurisdiction.
Frequently asked questions
Most jurisdictions multiply your property's assessed value by a local tax rate (often expressed as a millage rate). The assessed value is set by a local assessor and may differ from market value, and exemptions can reduce the taxable amount.
Often, yes. Many lenders collect a portion of the annual property tax with each monthly mortgage payment, hold it in escrow, and pay the county when the bill is due. Owners without a mortgage usually pay the county directly.
Bills commonly rise because of a reassessment that increased your home's assessed value, a higher local tax rate set to fund budgets, or the loss of an exemption. A rising local market can push assessed values up even without any change to the home.
Yes. Property tax is owed to the local government for as long as you own the property, regardless of whether there is a mortgage. Once the loan is gone, you typically pay the county directly instead of through escrow.
Possibly. Many jurisdictions offer exemptions, such as homestead exemptions for primary residences, and most allow you to appeal an assessment you believe is too high. Eligibility and process vary by location, so check with your local assessor.
