Property tax on a house depends on your location and your home's assessed value, not on a fixed national rate
There is no single answer to what property tax costs because every state, county, and sometimes city sets its own tax rate. A house worth $300,000 might cost $3,000 a year in property tax in one county and $6,000 in another, even in the same state. The amount you pay is calculated by multiplying your home's assessed value by your local tax rate, which is usually expressed as a percentage or as dollars per $1,000 of assessed value.
Your assessed value is not the same as what you paid for the house or what it would sell for today. A local assessor estimates the value, and that estimate is what the tax is based on. The tax rate itself is set by your county or municipality and can change year to year depending on local budget needs.
Key Takeaways
- Property tax rates vary by state and county, ranging from less than 0.3% of home value in some areas to over 2% in others.
- Your property tax bill is calculated by multiplying your home's assessed value (set by a local assessor) by your local tax rate.
- Most homeowners pay property tax as part of their monthly mortgage payment through an escrow account, not directly to the county.
- Your assessed value can change every year or every few years depending on your state's reassessment schedule.
- You can usually find your current property tax rate and bill through your county assessor's office website or property records.
How your local tax rate is determined
Your county or city government sets a tax rate based on how much money it needs to collect for schools, roads, emergency services, and other public expenses. If your county needs $50 million and the total assessed value of all property in the county is $5 billion, the rate would be 1% of assessed value. When the county's budget grows, the rate often rises with it.
Some states cap how much the tax rate can increase year to year, and some allow voters to approve rate changes. Others let the rate adjust freely. This is why two neighboring counties can have very different rates even though they provide similar services.
What your home's assessed value actually is
The assessed value is an estimate of what your house is worth, set by your county or township assessor. It is usually lower than the market value (what you could sell it for), but not always. The assessor may visit your home, review recent sales of similar homes nearby, or use a computer model to estimate the value.
Assessed values are typically updated every one to four years, depending on your state's reassessment schedule. When you buy a house, the assessed value often jumps to match your purchase price, because that is proof of what the market thinks it is worth. After that, it may increase slowly each year or stay the same until the next full reassessment.
How property tax is usually paid
If you have a mortgage, your lender almost certainly requires you to pay property tax through an escrow account. This means your monthly mortgage payment includes a portion set aside for taxes (and usually homeowners insurance and mortgage insurance too). Your lender collects this money and pays the county on your behalf when the bill comes due, usually once or twice a year.
If you own your home outright with no mortgage, you receive a property tax bill directly from your county assessor or tax collector and pay it yourself. The bill typically arrives once or twice a year, depending on your location. If you do not pay, the county can place a lien on your home or eventually foreclose.
Why your property tax bill changes year to year
Your bill can increase for two reasons: your assessed value went up, or your tax rate went up. Sometimes both happen in the same year. A reassessment might raise your home's value by 10% or 20%, which directly raises your tax bill by that amount. A rate increase set by the county affects all homeowners equally.
Some states allow homeowners to challenge their assessed value if they believe it is too high. This is called filing an appeal or grievance, and the process and important date vary by state. If you think your assessment is wrong, check your county assessor's website for the appeal important date and instructions.
Finding your property tax rate and bill
Your county assessor's office maintains public records of all property values and tax rates. You can usually search by address on the county website and see your assessed value, your tax rate, and your current or past bills. Some counties also let you view the assessor's notes on why your home was valued at a certain amount.
If you cannot find the information online, call your county assessor's office directly. They can tell you your assessed value, your tax rate, and what your next bill will be. If you are buying a house, your real estate agent or title company can also provide an estimate of annual property tax based on the purchase price and local rate.
How property tax differs from income tax and sales tax
Property tax is a local tax based on what you own, not what you earn or spend. It funds local services like schools and police. Income tax is based on your salary and is collected by the federal government and most states. Sales tax is a percentage added to purchases and varies by state and sometimes by county.
Property tax is usually the largest tax bill a homeowner pays each year. In some states it is much larger than state income tax. In others, income tax is higher. The balance depends on how your state chooses to fund its government.
Frequently Asked Questions
Is property tax the same everywhere in my state?
No. Each county and sometimes each city sets its own rate. Two towns in the same state can have rates that differ by 1% or more, which means hundreds of dollars difference on the same house. Check your specific county's rate, not your state's average.
Can I deduct property tax from my federal income tax?
You can deduct up to $10,000 of state and local taxes (including property tax) on your federal return if you itemize deductions instead of taking the standard deduction. Whether this helps depends on your total deductions and income. Consult a tax professional for your situation.
What happens if I do not pay my property tax bill?
The county can charge penalties and interest, place a lien on your home, and eventually foreclose and sell the property to recover the unpaid tax. If you cannot pay, contact your county tax collector about payment plans or hardship programs that may be available.
Does my property tax go down if my house value drops?
Not automatically. Your assessed value is updated on a schedule set by your state, which might be every year or every few years. If your home's market value falls significantly between reassessments, you can file an appeal to have the assessed value lowered.
How do I estimate property tax before buying a house?
Multiply the purchase price by your county's tax rate (expressed as a decimal). For example, a $300,000 house in a county with a 1.2% rate would cost about $3,600 per year. Ask your real estate agent or the county assessor for the exact rate, as it may vary by school district or municipality.
