You bought a house. Congratulations. Now here comes the part nobody warned you about.
Your mortgage payment probably includes property taxes, tucked inside something called escrow. But most first-time buyers have no idea how much they're actually paying, when the deadlines are, or whether they're eligible for exemptions that could save them hundreds of dollars a year.
This is the cheat sheet you should've gotten at closing.
How Property Taxes Actually Work
Property taxes are local taxes charged by your county (and sometimes your city, school district, or special district) based on the assessed value of your home. The money funds schools, roads, fire departments, libraries... basically everything local government does.
Here's the formula:
Assessed Value x Tax Rate = Your Annual Property Tax Bill
Your county determines both the assessed value (their estimate of what your home is worth) and the tax rate (set by local taxing authorities). You can't control the rate, but you can challenge the assessment if you think it's wrong.
Tax rates vary wildly. In New Jersey, the average effective rate is over 2%. In Hawaii, it's under 0.3%. Same house, dramatically different bills depending on where you live. Check out our state comparison guides to see where your state falls.
When Do You Pay?
This is the part that trips people up. Every state has different due dates. Some states bill once a year. Most bill twice... typically spring and fall. A few bill quarterly.
For example:
- ›Texas: January 31 (one annual deadline)
- ›California: December 10 (first installment) and April 10 (second)
- ›Illinois: Varies by county, but typically June and September
- ›New York: Depends on whether you're in NYC or elsewhere
Find your exact due date here by searching for your state and county.
Escrow: The Thing You're Already Paying
If you have a mortgage, there's a good chance your property taxes are being paid through escrow. Here's how it works:
- ›Your lender estimates your annual property tax bill
- ›They divide it by 12
- ›That amount gets added to your monthly mortgage payment
- ›The money sits in an escrow account
- ›When taxes are due, your lender pays the county directly
The upside: You don't have to remember deadlines or come up with a lump sum.
The downside: If your taxes go up, your mortgage payment goes up too... sometimes with no warning beyond a letter you might not read carefully. This is called an escrow adjustment, and it surprises first-time homeowners every year.
Also: escrow isn't foolproof. Lenders occasionally miss payments or underfund the account. Check your county's records annually to confirm your taxes were actually paid. If they weren't, you're on the hook... not your lender.
Exemptions You're Probably Missing
This is the biggest money most first-time buyers leave on the table.
Homestead Exemption: Most states offer some form of homestead exemption that reduces the taxable value of your primary residence. In Texas, it's a $100,000 reduction off your assessed value for school district taxes. In Florida, it's $50,000. In many states, you have to apply... it's not automatic.
If you bought mid-year: The previous owner may have been receiving exemptions that don't transfer to you. You need to file your own homestead exemption application, usually within a year of purchase.
Other exemptions to check:
- ›Senior exemptions (for parents or grandparents you're buying with)
- ›Veteran/military exemptions
- ›Disability exemptions
- ›Energy efficiency credits (some states offer property tax breaks for solar panels or energy upgrades)
Contact your county assessor's office or check your state page for what's available.
What If You Think Your Assessment Is Too High?
It happens all the time... especially in a market where home values have been volatile. If your county assessed your home higher than comparable recent sales suggest, you can appeal.
The process is simpler than most people think, and you don't need a lawyer. We've got a full walkthrough here: How to Appeal Your Property Tax Assessment.
The short version: find 3-5 similar homes that sold for less than your assessed value, file before the deadline, and show up to the hearing.
The Five Things to Do Right Now
- ›Find your county's due dates. Search for your state and county on our homepage so you know when your next bill is due.
- ›Sign up for a reminder. On your county page, enter your email. We'll remind you before the deadline.
- ›File for your homestead exemption. If you haven't already, do this today. It's free money.
- ›Verify escrow is paying your taxes. Log into your county's property records portal and confirm the payments are showing up.
- ›Check your assessment. Look at your property record card for errors. Compare to recent sales in your neighborhood.
Property taxes aren't complicated once you understand the basics. The expensive part is not paying attention.
