Property Tax
Property Tax
Quick Definition
Property tax is an annual tax assessed by local governments — counties, municipalities, and school districts — on real property (land and buildings). It is calculated by multiplying the property's assessed value by the local tax rate (mill rate). Property taxes fund essential local services: public schools, roads, emergency services, parks, and local government operations. For homeowners, property taxes typically represent 1-2% of the home's value annually — a major ongoing ownership cost.
What It Means
Property tax is unavoidable for real estate owners. Unlike income tax (which you can minimize through deductions and planning) or sales tax (which you can partially avoid), property tax is due every year regardless of income, profitability, or occupancy. For rental property investors, it is a direct operating expense that reduces NOI. For homeowners, it is a cost of living that continues indefinitely.
How Property Tax Is Calculated
Property Tax = Assessed Value × Mill Rate
Where 1 mill = $1 per $1,000 of assessed value = 0.1%
| Component | Description |
|---|---|
| Assessed value | County assessor's estimate of property value (may differ from market value) |
| Assessment ratio | Percentage of market value used as assessed value (varies by jurisdiction) |
| Mill rate | Total tax rate combining all taxing districts (school, county, city, special districts) |
| Exemptions | Reductions to assessed value (homestead, senior, veteran, disability) |
Example calculation:
| Item | Value |
|---|---|
| Market value | $400,000 |
| Assessment ratio | 85% |
| Assessed value | $340,000 |
| Less: Homestead exemption | -$25,000 |
| Taxable value | $315,000 |
| Mill rate (total) | 22 mills (2.2%) |
| Annual property tax | $315,000 × 0.022 = $6,930 |
Average Property Tax Rates by State (2024)
| State | Average Effective Rate | Average Annual Bill (median home) |
|---|---|---|
| New Jersey | 2.23% | ~$9,500 |
| Illinois | 2.08% | ~$6,500 |
| Connecticut | 1.79% | ~$6,200 |
| New Hampshire | 1.77% | ~$6,100 |
| Texas | 1.68% | ~$5,500 |
| US Average | ~1.10% | ~$3,200 |
| Alabama | 0.41% | ~$900 |
| Hawaii | 0.28% | ~$2,100 (high values, low rate) |
| Louisiana | 0.55% | ~$1,100 |
Key Exemptions and Reductions
| Exemption Type | Description | Typical Savings |
|---|---|---|
| Homestead exemption | Primary residence discount | $500-$50,000 off assessed value |
| Senior exemption | Age 65+ discount | Additional $5,000-$25,000 reduction |
| Veteran/disability | Military service or disability | Partial to full exemption |
| Agricultural exemption | Farmland assessed at agricultural use value | Massive reduction on rural land |
| Senior freeze | Lock assessed value for seniors | Prevents increases for fixed-income owners |
| Circuit breaker | Cap property tax at % of income | State programs for low-income owners |
Homestead exemption is automatic in most states for primary residences — but requires filing a one-time application. Many new homeowners miss this and overpay for years.
Property Tax and Escrow
Most mortgage lenders require property taxes to be escrowed:
- Lender collects 1/12 of annual tax bill with each monthly mortgage payment
- Funds held in escrow account
- Lender pays the tax authority when bills are due (typically semi-annually or annually)
- Annual escrow analysis ensures account balance is adequate
Escrow cushion: Lenders are allowed to maintain a cushion of up to 2 months of escrow payments to ensure funds are available for fluctuating tax bills. This is why your initial escrow deposit at closing may seem large.
Appealing Your Property Tax Assessment
Property taxes are appealable — if you believe your assessed value is too high:
| Step | Description |
|---|---|
| 1. Review assessment | Compare assessed value to recent comparable sales |
| 2. Check for errors | Wrong square footage, wrong number of bathrooms, incorrect lot size |
| 3. Gather comps | Find 3-5 similar properties that sold recently at lower prices |
| 4. File appeal | Submit informal appeal to assessor's office |
| 5. Formal hearing | If informal appeal fails, request board of review hearing |
| 6. Tax court | Last resort for significant disputes |
Success rate: Well-prepared property tax appeals succeed roughly 30-40% of the time. The savings can be substantial — a successful appeal reducing assessed value by $50,000 saves $550-$1,000/year in taxes at typical rates.
Property Tax Deductibility
The Tax Cuts and Jobs Act (2017) capped the deduction for state and local taxes (SALT):
| Tax Treatment | Rule |
|---|---|
| Primary residence | Deductible up to $10,000 SALT cap ($5,000 married filing separately) |
| Investment/rental property | Fully deductible as operating expense against rental income (no SALT cap) |
| Business property | Fully deductible as business expense |
The $10,000 SALT cap significantly hurt homeowners in high-tax states (NJ, IL, CT, NY) who previously deducted $15,000-$30,000+ in annual property taxes.
Key Points to Remember
- Property tax = assessed value × mill rate — levied annually by local governments
- Funds schools, infrastructure, and local services — largest local revenue source
- Effective rates range from 0.28% (Hawaii) to 2.23% (New Jersey)
- Homestead exemptions reduce taxable value for primary residences — always file if eligible
- Most mortgages require escrow — 1/12 of tax bill collected monthly, paid by lender
- Investment property taxes are fully deductible against rental income; primary residence taxes capped at $10,000 SALT limit
Frequently Asked Questions
Q: Why did my property tax increase when I didn't make any improvements? A: Property taxes can increase due to general assessment increases (county reassessment of all properties), increased mill rates from school or municipal budget increases, or expiration of exemptions or abatements. Most jurisdictions conduct mass reassessments every 3-5 years, updating all assessed values to reflect current market conditions. When home values rise 30-40% (as they did 2020-2022), reassessments in many areas caused dramatic property tax increases even without individual improvements.
Q: If I buy a home, does my property tax stay the same as the previous owner's? A: In most states, no — the property is reassessed to the purchase price when it changes hands. States like California (Proposition 13) are major exceptions: assessed value is locked at the purchase price and can only increase by a maximum 2% per year regardless of market appreciation. This creates massive tax disparities between long-term owners and new buyers in California, which has significant housing market implications.
Q: Are property taxes always current when I buy a home? A: The title search and closing process verifies that property taxes are current. Any delinquent taxes must be paid at closing — title insurance covers any taxes that were undisclosed. The buyer typically receives a credit from the seller for property taxes accrued but not yet paid (pro-rated through closing date). This is handled by the settlement agent as part of closing, so buyers receive a clean property tax slate at purchase.
