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 public schools, roads, emergency services, parks, and local government operations. For homeowners, property taxes typically represent 1 to 2% of the home's value annually, making them one of the largest ongoing costs of homeownership.
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.
The national average effective property tax rate is approximately 1.05%, according to U.S. Census Bureau data. The average U.S. household pays $3,119 per year in property taxes. But the spread between states is dramatic: Hawaii homeowners pay 0.27% of their home value, while New Jersey homeowners pay 2.11% or more.
How Property Tax Is Calculated
Property Tax = Assessed Value x 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 x 0.022 = $6,930 |

|---|---|---|
| Hawaii | 0.27% | $2,239 |
| Alabama | 0.38% | $788 |
| Colorado | 0.48% | $2,602 |
| Utah | 0.52% | $2,525 |
| Delaware | 0.50% | $1,768 |
| West Virginia | 0.53% | $865 |
| Louisiana | 0.55% | $1,180 |

Note that Hawaii's low rate is offset by high median home values ($839,100), so the dollar bill is still sizeable. Alabama has both a low rate and low home values, making it the lowest absolute property tax burden in the nation.
Key Exemptions and Reductions
| Exemption Type | Description | Typical Savings |
|---|---|---|
| Homestead exemption | Primary residence discount | $500 to $50,000 off assessed value |
| Senior exemption | Age 65+ discount | Additional $5,000 to $25,000 reduction |
| Veteran/disability | Military service or disability | Partial to full exemption |
| Agricultural exemption | Farmland assessed at agricultural use value | Large reduction on rural land |
| Senior freeze | Lock assessed value for seniors | Prevents increases for fixed-income owners |
| Circuit breaker | Cap property tax at percentage 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
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 to 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 |
Well-prepared property tax appeals succeed roughly 30 to 40% of the time. The savings can be substantial: a successful appeal reducing assessed value by $50,000 saves $550 to $1,000 per year in taxes at typical rates.
Property Tax Deductibility and the SALT Cap
The Tax Cuts and Jobs Act (2017) originally capped the deduction for state and local taxes (SALT) at $10,000. On July 4, 2025, the One Big Beautiful Bill Act (OBBBA) raised the SALT cap significantly:
| Tax Year | SALT Cap (single/joint) | SALT Cap (MFS) | MAGI Phaseout Threshold |
|---|---|---|---|
| 2018 to 2024 | $10,000 | $5,000 | N/A |
| 2025 | $40,000 | $20,000 | $500,000 |
| 2026 | $40,400 | $20,200 | $505,000 |
| 2027 to 2029 | +1% annual increase | +1% annual increase | +1% annual increase |
| 2030+ | Reverts to $10,000 | Reverts to $5,000 | N/A |
The increased cap phases down for taxpayers with modified AGI above $500,000 (for 2025), reducing the cap by 30% of the excess income. Taxpayers with MAGI of $600,000 or more are fully phased out and limited to the original $10,000 cap. For 2026, the phaseout threshold rises to $505,000.
| Tax Treatment | Rule |
|---|---|
| Primary residence | Deductible up to SALT cap ($40,400 for 2026) |
| Investment/rental property | Fully deductible as operating expense against rental income (no SALT cap) |
| Business property | Fully deductible as business expense |
The SALT cap increase provides meaningful relief for homeowners in high-tax states (NJ, IL, CT, NY) who previously lost deductions on property taxes above $10,000. However, the cap reverts to $10,000 in 2030 unless Congress acts again.
Key Points to Remember
- Property tax = assessed value x mill rate, levied annually by local governments
- The national average effective rate is approximately 1.05%; the average household pays $3,119 per year
- Effective rates range from 0.27% (Hawaii) to 2.11% (New Jersey), a spread that translates to thousands of dollars per year on the same home
- 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
- The SALT cap was raised to $40,000 for 2025 and $40,400 for 2026, with phaseouts above $500,000/$505,000 MAGI
- Investment property taxes are fully deductible against rental income with no SALT cap
Common Mistakes to Avoid
- Not filing for homestead exemption: Many states require a one-time application to receive the homestead exemption on your primary residence. Missing this filing means overpaying every year you own the home. Check with your county assessor after closing.
- Assuming assessed value equals market value: Assessed value is the assessor's estimate, which may be higher or lower than what your home would actually sell for. If the assessment is too high, you are overpaying. Review your assessment annually and appeal if it exceeds market value.
- Ignoring the SALT phaseout: The new $40,000 SALT cap sounds generous, but if your MAGI exceeds $500,000 (for 2025) or $505,000 (for 2026), the cap phases down rapidly. At $600,000 MAGI for 2025, you are back to the $10,000 cap. High earners in high-tax states may see less benefit than expected.
- Forgetting that investment property taxes are not subject to the SALT cap: If you own rental property, property taxes are fully deductible as an operating expense against rental income on Schedule E. The SALT cap only applies to personal residence taxes on Schedule A.
- Not appealing an inflated assessment: Property tax appeals succeed 30 to 40% of the time when well-prepared. Many homeowners assume the assessment is fixed and never challenge it, leaving money on the table year after year.
- Underestimating property tax when house hunting: Buyers often focus on the mortgage payment and forget to budget for property taxes, which can add hundreds or thousands per month. A $400,000 home in New Jersey carries roughly $8,440 in annual property taxes, while the same home in Alabama carries about $1,520. Always factor property taxes into your total cost of ownership.

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 to 5 years, updating all assessed values to reflect current market conditions. When home values rise 30 to 40% (as they did 2020 to 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.
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 (prorated through closing date). This is handled by the settlement agent as part of closing, so buyers receive a clean property tax slate at purchase.
Q: How does the new SALT cap work for 2025 and 2026? A: The OBBBA raised the SALT cap from $10,000 to $40,000 for 2025 and $40,400 for 2026. However, the cap phases down for taxpayers with MAGI above $500,000 (2025) or $505,000 (2026), reducing the cap by 30% of excess income. At $600,000 MAGI (2025), the cap reverts to $10,000. The increased cap is scheduled to revert to $10,000 in 2030 unless Congress extends it.
Q: Can I deduct property taxes on a rental property? A: Yes. Property taxes on investment or rental property are fully deductible as an operating expense on Schedule E, with no SALT cap limitation. The SALT cap only applies to property taxes on your personal residence claimed as an itemized deduction on Schedule A.
