Property taxes are due once a year in most places, though some counties split the bill into two payments
The frequency depends on where you own property. Most U.S. counties bill property taxes annually — you get one bill per year and pay it by a single important date. However, roughly a third of states split the annual tax into two installments, usually due in spring and fall. A smaller number of counties bill quarterly or allow monthly payments through an escrow account if you have a mortgage.
Your mortgage lender may handle the payment for you. If your loan includes an escrow account, the lender collects a portion of your property tax each month along with your mortgage payment, then pays the county on your behalf when the bill comes due. This means you never see a separate property tax bill — the cost is built into your monthly mortgage payment. If you own the home outright or have a loan without escrow, you receive the bill directly from your county assessor or tax collector and must pay it yourself.
Key Takeaways
- Most counties bill property taxes once per year, though about one-third of states split the bill into spring and fall payments.
- If you have a mortgage with an escrow account, your lender collects property tax monthly and pays the county automatically.
- Homeowners without mortgages or with loans that do not include escrow receive a bill directly and must pay by the county important date.
- The bill arrives at different times depending on your county — some send bills in January, others in summer or fall.
- Missing a property tax payment can result in penalties, interest, and eventually a tax lien or foreclosure.
How the payment schedule works if you have a mortgage
When you take out a mortgage, the lender typically requires an escrow account as part of the loan. Each month, you pay your mortgage principal and interest plus a portion of your estimated annual property taxes and homeowners insurance. The lender holds this money in escrow and releases it to pay your property tax bill and insurance premiums when they come due.
The escrow amount changes once a year, usually in the fall. Your lender reviews the previous year's actual tax bill and insurance costs, then adjusts your monthly payment up or down for the coming year. If your property taxes or insurance rose, your monthly payment will increase. If they fell, it may decrease. You receive a statement showing the breakdown of your monthly payment and how much is going toward taxes, insurance, and principal and interest.
Some lenders allow you to opt out of escrow if you have a strong payment history and enough equity in the home, but this is uncommon. Most require it for the life of the loan because it protects the lender's investment — they know the property taxes and insurance will be paid on time.
Payment important date vary by county and state
There is no single national property tax important date. Each county sets its own due date, and these dates are scattered throughout the year. Some counties bill in January with a March or April important date. Others send bills in summer with a September or October important date. A few bill in fall with a important date in December or January of the following year.
You can find your county's important date by contacting the county assessor's office, tax collector's office, or checking the county website. The bill itself always shows the due date. If you pay through escrow, your lender handles the timing, so you do not need to track it yourself. If you pay directly, mark the important date on your calendar — property taxes are not optional, and missing the important date triggers penalties and interest.
Some counties offer a small discount if you pay early, usually 2 to 5 percent. A few allow you to set up automatic monthly payments even if you own the home outright, which spreads the cost across the year rather than paying a lump sum.
What happens if you miss a payment
Property tax bills are not like utility bills. If you do not pay by the important date, the county when ready begins charging interest and penalties. The interest rate varies by state but typically ranges from 5 to 18 percent per year, compounding monthly. Penalties are usually a flat percentage of the unpaid tax, often 5 to 10 percent, assessed on the first day after the important date.
If the bill remains unpaid for several months, the county may place a tax lien on your property. This lien gives the county a legal claim against your home. You cannot sell or refinance the property without paying off the lien first. In some states, the county can sell the lien to a third party, who then has the right to foreclose on your home if the taxes remain unpaid for a set period — usually two to five years, depending on the state.
If you are struggling to pay, contact your county tax collector when ready. Some counties offer payment plans, tax deferral programs for seniors or disabled homeowners, or hardship relief. Acting early is far cheaper than waiting for penalties and interest to accumulate.
Differences between annual, semi-annual, and quarterly billing
States that use annual billing send one bill per year. You pay the full year's tax in a single payment by one important date. This is straightforward but requires you to have the full amount available at once.
States with semi-annual billing split the year's tax into two equal installments, typically due in spring and fall. This spreads the cost across two payments and is common in California, Texas, Illinois, and several other large states. Each installment is roughly half the annual tax.
A few counties use quarterly billing, dividing the year into four payments. This is less common but offers the most flexibility for budgeting. Some homeowners with mortgages can also arrange monthly payments through escrow, which effectively spreads the annual tax across twelve payments.
How property taxes are assessed and billed
Your county assessor determines the assessed value of your property, usually every one to three years. The county then multiplies that value by the local tax rate (called the millage rate) to calculate your annual tax bill. The assessed value is not the same as the market value — it is often lower and is meant to reflect what the property would sell for in an arm's-length transaction.
After the assessor calculates the bill, the county tax collector or assessor's office mails it to you or makes it available online. The bill shows the assessed value, the tax rate, the total amount due, and the due date. If you disagree with the assessed value, most counties allow you to file a formal challenge called an assessment appeal or tax protest, usually within 30 to 60 days of receiving the bill.
Frequently Asked Questions
Can I pay my property taxes monthly instead of in one lump sum?
If you have a mortgage with escrow, your lender already collects property taxes monthly. If you own the home outright, some counties allow voluntary monthly payment plans, but you must request this from the tax collector. Not all counties offer this option, so ask your local tax office what is available.
What if my property tax bill is wrong?
You can file an assessment appeal with your county assessor, usually within 30 to 60 days of receiving the bill. Bring evidence of comparable property sales, recent appraisals, or documentation of property damage that reduces value. The process and timeline vary by county, so contact your assessor's office for specific instructions.
Do I still owe property taxes if I am behind on my mortgage?
Yes. Property taxes and mortgage payments are separate obligations. If your mortgage includes escrow, the lender pays property taxes from that account even if you are behind on the mortgage itself. If you own outright or have a loan without escrow, you must pay property taxes regardless of mortgage status, or the county can place a lien on your home.
How do I find out when my property taxes are due?
Contact your county tax collector's office or assessor's office by phone or visit their website. You can also look up your property online using your county's property tax portal, which usually shows your bill, due date, and payment history. If you have a mortgage, your lender's escrow statement also lists the due date.
What is the difference between property tax and homeowners insurance?
Property tax is a tax paid to your county based on your home's assessed value. Homeowners insurance is a private insurance policy that covers damage to your home and liability. If you have a mortgage with escrow, your lender collects both and pays them separately — property taxes go to the county, and insurance premiums go to your insurance company.
