Property Taxes Explained: What Every Homeowner Should Know
Property taxes are one of the largest ongoing costs of homeownership, yet many buyers don’t fully understand how they work until after they’ve purchased. Knowing how property taxes are calculated, what they fund, and how to manage them helps you budget accurately and potentially save money through available exemptions and appeals.
How Property Taxes Work
Property taxes are levied by local governments—counties, cities, school districts, and special districts—to fund public services including schools, roads, police and fire departments, parks, and infrastructure. The amount you owe is determined by two factors: your property’s assessed value and the local tax rate (also called the mill rate or millage rate).
The basic formula is straightforward: Assessed Value × Tax Rate = Annual Property Tax. For example, a home assessed at $350,000 in an area with a combined tax rate of 1.2% would owe $4,200 per year, or $350 per month. This monthly amount is typically collected through your mortgage escrow account.
How Properties Are Assessed
Your county assessor’s office determines your property’s assessed value, which may differ from market value depending on your state’s assessment practices. Some states assess at 100% of market value, while others use a percentage (assessment ratio). Reassessments occur on different schedules—annually in some jurisdictions, every few years in others, or triggered by property sales or improvements.
After purchasing a home, your property may be reassessed at the purchase price, potentially increasing taxes significantly if the previous owner held the property for years at a lower assessed value. Factor this into your budget when calculating how much house you can afford.
Property Tax Rates Across the Country
Property tax rates vary dramatically by location. Some states like New Jersey, Illinois, and Connecticut have effective rates above 2%, while others like Hawaii, Alabama, and Colorado are below 0.6%. On a $400,000 home, that’s the difference between $8,000 and $2,400 per year—a significant factor in total housing costs.
When comparing homes in different locations, always factor in property tax rates. A lower-priced home in a high-tax area may actually cost more monthly than a higher-priced home in a low-tax area.

Tax Exemptions and Reductions
Many jurisdictions offer exemptions that reduce your tax burden. Homestead exemption is available in many states for your primary residence, reducing the assessed value by a set amount—often $25,000 to $50,000. Senior exemptions provide additional reductions for homeowners over 65. Veteran exemptions offer tax breaks for military veterans. Disability exemptions reduce taxes for homeowners with qualifying disabilities.
These exemptions aren’t automatic—you must apply for them. Check with your local assessor’s office shortly after purchasing to ensure you’re claiming every exemption you qualify for.
How to Appeal Your Property Tax Assessment
If you believe your property is overassessed, you have the right to appeal. Successful appeals can save you hundreds or thousands per year. Start by reviewing your assessment notice for accuracy—check square footage, room counts, lot size, and property condition. If the assessed value exceeds what comparable homes have recently sold for, you have grounds for an appeal.
Gather evidence including recent sales of similar homes, photos documenting any condition issues that might reduce value, and an independent appraisal if warranted. File your appeal within the deadline specified on your assessment notice—missing the deadline forfeits your right to appeal for that year.
Property Taxes and Your Monthly Payment
For most homeowners, property taxes are collected monthly as part of the mortgage payment and held in an escrow account. Your lender pays the tax bills on your behalf when they come due. Because tax rates and assessed values can change, your monthly escrow payment may adjust annually, causing your total mortgage payment to fluctuate even with a fixed-rate loan.
