How Property Taxes Work and What New Homeowners Need

How Property Taxes Work and What New Homeowners Need to Know

Property taxes are one of the largest ongoing costs of homeownership, and one of the least understood. They affect your monthly mortgage payment, your total housing budget, and even your decision about where to buy. Here is how they work, how they are calculated, and what you can do about them.

The Basics: How Property Taxes Are Calculated

Property taxes are calculated using two numbers: your property's assessed value and your local tax rate (sometimes called the mill rate or millage rate).

Assessed value is what your local tax assessor determines your property is worth for tax purposes. This is not necessarily the same as market value or the price you paid. Many jurisdictions assess properties at a percentage of market value -- some at 100%, others at 80%, 60%, or even lower. The assessment methodology varies by state and county.

Tax rate is set by local taxing authorities -- your county, city, school district, and any special districts (fire, water, library, etc.). Each entity sets its own rate, and they are combined into one total rate that applies to your property.

The formula: Assessed Value x Tax Rate = Annual Property Tax

For example: a home assessed at $350,000 in an area with a total tax rate of 1.3% pays $4,550 per year, or about $379 per month.

How Assessments Work

Your property is assessed by the county or municipal assessor's office. Assessments happen at different intervals depending on your location -- annually in some places, every few years in others. Some states reassess only when a property is sold or significantly improved.

Assessors use several methods to determine value:

• Comparable sales approach: Looking at recent sales of similar properties in your area
• Cost approach: Estimating what it would cost to build your home today, minus depreciation
• Income approach: Used primarily for commercial and rental properties, based on the income the property generates

When you buy a home, many jurisdictions will reassess the property at or near the purchase price. If you bought a home for $450,000 that was previously assessed at $320,000, expect your tax bill to increase substantially. This surprises many new homeowners who base their budget on the seller's tax bill without realizing it will go up.

How Property Taxes Are Paid

If you have a mortgage, your property taxes are almost always collected through your escrow account. Your lender collects one-twelfth of your estimated annual tax bill each month as part of your mortgage payment, holds it in escrow, and pays the tax bill on your behalf when it is due.

Your escrow payment is based on an estimate. Once a year, your servicer performs an escrow analysis comparing what they collected to what they actually paid. If there is a shortage, your monthly payment increases. If there is a surplus, you may receive a refund or a reduced payment.

Tax bills are typically due once or twice a year, depending on your jurisdiction. Even though you pay monthly through escrow, the actual tax payment to the county happens on the local schedule.

If you own your home outright or do not have an escrow account, you are responsible for paying property taxes directly to your county tax collector by the due date. Late payments incur penalties and interest, and prolonged non-payment can result in a tax lien or tax sale of your property.

Why Your Tax Bill Changes

Property taxes are not static. They change for two main reasons:

Your assessed value changes. If property values in your area increase, your assessment will likely increase at the next reassessment. If you add a major improvement -- a new addition, finished basement, or pool -- your assessed value will rise to reflect the added value.

Tax rates change. Local governments set tax rates annually based on their budget needs. If your school district passes a bond measure or your city increases spending, the tax rate goes up. These rate changes affect every property owner in the jurisdiction.

In practice, property taxes tend to increase over time. Budget for this. What you pay in year one is likely less than what you will pay in year five or ten.

Property Tax Exemptions

Most states offer exemptions that reduce your taxable assessed value. Common exemptions include:

• Homestead exemption: Available to owner-occupants, this reduces your assessed value by a fixed amount (for example, $25,000 to $50,000 or more, depending on the state). You must apply for this -- it is not automatic in most places.
• Senior citizen exemption: Additional reductions for homeowners above a certain age, often with income requirements.
• Veteran exemption: Partial or full property tax exemptions for veterans, with enhanced benefits for disabled veterans.
• Disability exemption: Available in many states for homeowners with qualifying disabilities.
• Agricultural exemption: Reduced assessments for land used for farming or ranching.

Apply for every exemption you qualify for. The homestead exemption alone can save you hundreds or thousands of dollars per year, and failing to file is essentially leaving money on the table.

How to Appeal Your Property Tax Assessment

If you believe your property is assessed too high, you have the right to appeal. The process varies by jurisdiction, but generally involves these steps:

• Review your assessment notice for accuracy. Check that the property details (square footage, number of bedrooms, lot size) are correct. Errors are more common than you would expect.
• Research comparable properties. Find recently sold homes similar to yours that sold for less than your assessed value, or find similar homes with lower assessments.
• File a formal appeal with your local assessor's office or board of review within the deadline (often 30 to 90 days after you receive your assessment notice).
• Present your evidence at a hearing. Bring your comparable sales data, photos, and any documentation of issues that reduce your home's value.

Appeals are free to file and worth pursuing if your assessment seems off. Success rates vary, but many homeowners who appeal do receive a reduction.

Property Taxes and Your Mortgage Payment

When you are shopping for a home, remember that the listing price is only part of the story. A $400,000 home in a low-tax area might have a lower total monthly payment than a $350,000 home in a high-tax area. Always factor property taxes into your comparison.

Your lender includes property taxes in your qualifying ratios. Higher taxes mean a higher total payment, which means you qualify for less. This is especially relevant when comparing homes across different counties or states.

First-Year Tax Proration at Closing

At closing, property taxes are prorated between the buyer and seller based on the closing date. If the seller has already paid taxes for the full year and you close in June, you reimburse the seller for the remaining months. If taxes have not been paid yet, the seller credits you for their share. Your closing disclosure will show exactly how this is calculated.
