How Property Taxes Work: A Plain-English Guide for New Homeowners

If you just bought a home, your first property tax bill can be confusing. This guide explains how property taxes work in plain English: who sets your home’s value, who sets the tax rate, how the bill is calculated, and what you can do if it seems too high. Rules differ by state and county, so we show real examples from official sources and point you to where to check your own numbers.

What are property taxes, and who collects them?

Property taxes are local taxes based on the value of real estate. They pay for schools, roads, police, fire protection and other local services. Your county, city, school district and special districts (such as water, library or hospital districts) can each tax your home, and their charges add up to one bill.

In Texas, for example, the state has no property tax at all. Local governments set the rates and collect the money, and more than 4,796 local taxing units in the state levy property taxes, according to the Texas Comptroller. The same basic idea applies across the country: property tax is local, and that is why your neighbor across a county line can pay a very different amount.

The system has three moving parts:

• The value of your home, set by a local assessor or appraisal district.
• Exemptions that reduce the taxable value, such as a homestead exemption.
• The tax rate, set by each local taxing body based on its budget.

How is your home’s assessed value set?

Your assessed value is the dollar figure the local assessor uses to tax your home. The assessor first estimates market value, usually by comparing your home with similar homes that sold recently. Then the local assessment rules turn that market value into an assessed value, which may be the full value or a fixed fraction of it.

New York’s tax department describes three ways assessors estimate value: comparing recent sales of similar homes (the most common method for houses), estimating the cost to rebuild minus depreciation plus land value, and, for rental buildings, looking at income (New York State Department of Taxation and Finance).

Market value vs. assessed value

Market value is what your home would likely sell for. Assessed value is what the tax system uses. They match only in places that assess at 100% of market value.

Many places use an assessment ratio (also called a level of assessment). New York gives this example: if a city assesses at 27% of market value, a home with a $100,000 market value has a $27,000 assessment (New York State Department of Taxation and Finance).

When is the value set?

Most places value property as of a fixed date each year. Texas appraisal districts value property as of January 1 (Texas Comptroller). California uses January 1 as its lien date too.

Caps on how fast values can rise

Some states limit yearly increases. In California, the assessed value of most property is the prior year’s value adjusted for inflation by up to 2%, but it resets to market value after a sale or new construction (California State Board of Equalization). That is why a new buyer in California can pay much more than a longtime neighbor in an identical house. Our homestead exemption guide covers caps in Florida and Texas, which apply to homesteads.

How are tax rates and levies set?

Each taxing body starts with a budget. It subtracts the money it expects from other sources, such as state aid and fees. What is left is the levy, the total amount it must raise from property owners. It then divides the levy by the total taxable value of all property in its area to get a rate.

New York’s tax department walks through the math with a sample town: a levy of $2,000,000 spread over $40,000,000 of total taxable value gives a rate of $50 per $1,000 of value, so a home with a $150,000 taxable assessment owes $7,500 to that town (New York State Department of Taxation and Finance).

Why your total rate is a stack of rates

Your home sits inside several taxing districts at once. Your bill lists each one with its own rate. Add them up to get your combined rate.

Hypothetical example. A home has a taxable value of $240,000 after exemptions. It sits in four districts:

The math is simple: $240,000 ÷ 1,000 × $21.50 = $5,160. Your real numbers will be on your tax bill or your county’s website.

Can your assessment rise while your taxes fall?

Yes. Rates are set after values are known. If values rise across your whole area but the budget stays flat, the rate can drop. The reverse also happens: your assessment can stay the same while a new school bond raises your bill. New York’s tax department lists budgets, other revenue, total taxable value and how the levy is split among municipalities as reasons a bill can change from year to year (New York State Department of Taxation and Finance).

When do property tax bills arrive, and when are they due?

Timing varies a lot. Some counties send one bill a year. Others split it into two or more installments. The safest move is to look up your county tax collector’s calendar the week you close on your home.

Two official examples:

• Texas: Many counties mail bills around October 1. Taxpayers generally have until January 31 of the next year to pay, and penalties and interest begin February 1 on most unpaid bills (Texas Comptroller).
• California: The second installment of secured property taxes is due without penalty by April 10, according to the state’s property tax calendar (California State Board of Equalization).

Taxes in your first year

When you buy a home, the seller usually pays taxes up to the sale date and you pay from that date on. IRS Publication 530 says the buyer is treated as paying the taxes beginning with the date of sale, and your settlement statement shows how the year was split (IRS). Keep that closing statement. You will want it at tax time.

How does an escrow account pay your property taxes?

Many lenders collect property taxes as part of your monthly mortgage payment. The money goes into an escrow account (called an impound account in some places), and your loan servicer pays the tax bill when it is due. The Consumer Financial Protection Bureau explains that because taxes and insurance premiums change, the escrow part of your payment changes too (CFPB).

That is why a higher tax bill often shows up first as a higher mortgage payment, sometimes a year later after the servicer’s annual review. For a full walk-through of shortages, surpluses and annual statements, read our guide to how a mortgage escrow account works.

What exemptions can lower your property tax?

An exemption removes part of your home’s value, or part of the tax, from the bill. The most common one for homeowners is a homestead exemption for your primary residence. Many states also offer extra relief for seniors, people with disabilities and veterans.

Amounts vary widely. Florida’s homestead exemption can reduce assessed value by up to $50,000, while California’s homeowners’ exemption is a $7,000 reduction in taxable value. In most places, you must apply, and the deadline is often early in the year. Missing it can cost you a full year of savings. Our guide to homestead exemptions explains how to apply and the common mistakes to avoid.

Can you deduct property taxes on your federal tax return?

Yes, but only if you itemize deductions instead of taking the standard deduction. Property taxes count toward the state and local tax (SALT) deduction. For tax year 2026, the combined SALT limit is $40,400, or $20,200 if you are married filing separately, according to the IRS.

Key points for tax year 2026 (the return you file in 2027):

• The limit covers all state and local taxes combined. That includes property taxes plus either state income tax or sales tax (IRS Topic 503).
• Higher incomes get a lower limit. The limit is reduced if your modified adjusted gross income is over $505,000 ($252,500 if married filing separately), but not below $10,000 ($5,000 if married filing separately) (IRS).
• Itemizing has to beat the standard deduction. For 2026, the standard deduction is $16,100 for single filers, $32,200 for married couples filing jointly and $24,150 for heads of household (IRS).
• Not everything on the bill counts. Charges for services such as water, sewer or trash pickup, and HOA fees, are not deductible as real estate taxes (IRS Topic 503).
• With escrow, deduct what was actually paid. You can deduct only the real estate taxes your lender actually paid from escrow to the taxing authority during the year (IRS Publication 530).

This is general information, not tax advice. A tax professional can tell you whether itemizing makes sense for your situation.

What should you do when your property tax bill rises?

Start by finding out why it went up. Compare this year’s bill with last year’s, line by line. The cause is usually one of three things: a higher assessed value, a higher tax rate in one or more districts, or a lost or missing exemption. Each one has a different fix.

1. Compare the values. Look at last year’s and this year’s assessed and taxable values. If taxable value jumped but assessed value did not, an exemption may be missing.
2. Compare the rates. If one district’s rate went up, that is a budget decision. You can speak at that body’s budget hearings or vote on future levies, but an assessment appeal will not change the rate.
3. Check your property record. Wrong square footage, an extra bathroom or a garage you do not have can inflate your value.
4. Confirm your exemptions. Make sure your homestead and any senior, disability or veteran exemptions are on the bill.
5. Look up the appeal deadline right away. Deadlines can be short. In Texas, for example, the usual deadline to protest is May 15 or 30 days after the notice was mailed, whichever is later (Texas Comptroller). Our step-by-step guide on how to appeal a property tax assessment explains how to build your case.
6. Plan for the escrow change. If you pay through escrow, expect your monthly payment to adjust. Build the higher amount into your home maintenance and ownership budget.

Keep paying on time while you sort things out, and ask your county how payments work while an appeal is pending. Late penalties can add up quickly.
