Property Tax Deduction
Property Tax Deduction
Property taxes are an annual expense for real-estate owners. For rental property, they're fully deductible against income with no cap. For primary residence, they're deductible only within the $10,000 state and local tax (SALT) cap, which combines property taxes, income taxes, and sales taxes. This cap has reshaped real-estate taxation for high-income homeowners.
Key takeaways
- Property taxes on rental real estate are fully deductible against rental income; no cap.
- Property taxes on primary residence are deductible only up to $10,000 combined with state income taxes and sales taxes (SALT cap).
- The SALT cap, introduced in 2017, is set to expire on December 31, 2025, unless Congress extends it.
- Property tax rates vary dramatically by state and locality: from 0.3% in Hawaii to 2.5% in New Jersey.
- For a $2 million home in New Jersey (effective rate ~1.2%) paying $24,000 annually in property tax, only $10,000 is deductible; $14,000 is lost.
Rental property: unlimited deduction
For investment properties, property taxes are a direct business expense, fully deductible against rental income. There is no cap. A $10 million commercial building paying $150,000 in annual property taxes deducts the full amount.
This is a major advantage over primary residence. The deduction encourages leverage and investment in real estate: the higher the property value, the higher the property tax, the larger the deduction, the lower the taxable income from the property.
Property-tax deductions also make real estate more competitive relative to other assets. A $1 million stock portfolio generating $40,000 in dividends has no property-tax offset. A $1 million rental property generating $40,000 in income may have $12,000 in property taxes (at an average 1.2% rate), reducing taxable income to $28,000.
Primary residence: the $10,000 SALT cap
The Tax Cuts and Jobs Act of 2017 capped the total deduction for state and local taxes (SALT) at $10,000 per taxpayer per year. This cap applies to:
- State income tax
- Local income tax (a few states and cities)
- Property taxes
- Sales taxes
- A combination of the above
Married couples filing jointly have a single $10,000 cap (not $10,000 each). For a high-income household in a high-tax state, the cap is binding.
Example: A married couple, resident in New York, with:
- Federal taxable income: $500,000.
- Combined New York state income tax: $50,000.
- New York City income tax: $3,750.
- Property taxes on primary residence: $20,000.
- Total SALT: $73,750.
Under the SALT cap, only $10,000 is deductible. The remaining $63,750 is disallowed. At a 40% combined federal-state marginal rate, this represents a $25,500 loss of tax deductions per year, or $255,000 over a decade.
The cap has reduced the attractiveness of primary-residence ownership in high-tax states like California, Massachusetts, Connecticut, and New York.
State variation: why property taxes matter differently in different places
Property-tax rates vary widely:
| State | Effective Rate | Reason |
|---|---|---|
| Hawaii | 0.28% | High home values, low tax base |
| Louisiana | 0.55% | Large state services funded differently |
| Wyoming | 0.61% | Low population, wealthy residents |
| Texas | 1.80% | No state income tax; property tax compensates |
| New Jersey | 2.49% | Highest in nation; funds schools |
In Texas, which has no state income tax, property taxes are the primary real-estate deduction. A $1 million home pays ~$18,000 in property tax (1.8% × $1M). This is deductible, but only if it fits in the $10,000 SALT cap. Since it exceeds the cap alone, state income tax cannot be deducted at all.
In Hawaii, a $1 million home pays only $2,800 in property tax (0.28%), leaving $7,200 of SALT cap room for state income tax.
This variation means that high-income real-estate buyers should consider property-tax rates when evaluating locations. A property in Texas has a higher ongoing tax cost per dollar of home value compared to Hawaii or Louisiana.
The $10,000 cap is a married-filing-jointly limit (with caveats)
The SALT cap applies per taxpayer, but married couples filing jointly get a single $10,000 cap, not $10,000 each. This creates planning considerations for high-income married couples:
If both spouses are high-income earners and one is contemplating a move to a different state with lower taxes, there may be a tax-filing advantage to filing separately (each gets a $5,000 SALT cap, but state tax laws vary on whether married-filing-separate is permitted).
Alternatively, a married couple might consider structuring property ownership in an entity (like an S-corp) that doesn't use individual SALT caps. However, this has other tax implications and is uncommon.
The expiration question and planning uncertainty
The SALT cap is set to expire on December 31, 2025, unless Congress extends it. In March 2024, there was bipartisan discussion of extending it, but no legislation has passed. Current law suggests the cap expires in 2026.
If the cap expires:
- A household paying $73,750 in SALT could deduct all of it.
- Tax savings at 40% rate: $29,500 per year, or $147,500 over five years.
If the cap is extended:
- The status quo continues, affecting high-income households in high-tax states.
This creates planning uncertainty. Real-estate buyers in high-tax states should factor both scenarios into 10-year cost-of-ownership projections.
Effective property-tax rates and after-tax returns
Property taxes reduce the effective after-tax yield on real estate. Consider two $1 million rental properties:
Property A (Texas): 1.8% property-tax rate = $18,000 annually.
- Gross rental income: $60,000.
- Operating expenses (excluding property tax): $20,000.
- Property tax: $18,000.
- Net: $22,000 (before depreciation, mortgage interest).
- After-tax yield (at 40% rate): $22,000 × 0.60 = $13,200, or 1.32% on $1M value.
Property B (Hawaii): 0.28% property-tax rate = $2,800 annually.
- Gross rental income: $60,000.
- Operating expenses (excluding property tax): $20,000.
- Property tax: $2,800.
- Net: $37,200 (before depreciation, mortgage interest).
- After-tax yield (at 40% rate): $37,200 × 0.60 = $22,320, or 2.232% on $1M value.
The property-tax differential ($18,000 – $2,800 = $15,200 annually) directly reduces after-tax returns. Over 30 years, this $15,200 annual difference compounds to a significant advantage for Hawaii property.
Interaction with depreciation and mortgage interest
Property taxes, mortgage interest, and depreciation are three separate deductions that stack:
Rental property with $1 million acquisition cost (70% to structure):
- Depreciation (27.5-year residential): $700K ÷ 27.5 = $25,454 annually.
- Mortgage interest ($700K loan at 6%): $42,000 annually.
- Property taxes (1.2% rate): $12,000 annually.
- Operating expenses: $20,000 annually.
- Total deductions: $99,454.
Rental income of $60,000 minus deductions of $99,454 = –$39,454 paper loss. This loss shelters up to $25,000 of other income (passive-loss rule exemption) and can carry forward indefinitely.
The combination of three deductions (depreciation, mortgage interest, property tax) is why real estate is such a tax-efficient investment.
Property-tax reform and forecasting
Some states have explored property-tax reform to reduce rates or cap increases. Proposition 13 in California (1978) limited property-tax increases to 2% annually, regardless of home appreciation. This has kept effective property-tax rates low in California (~0.8%) compared to Texas or New Jersey.
If states reform property taxes downward, real-estate deductions shrink, and after-tax returns fall. Conversely, if states raise property taxes (to fund schools or infrastructure), deductions increase for rental properties but hit the SALT cap for primary residences in high-income households.
As an investor, property-tax trends in your target markets matter. A 10% increase in property tax over a decade reduces after-tax yields by a few basis points annually.

The §121 exclusion allows up to $500,000 (married) or $250,000 (single) of gains on primary residence to be excluded from taxation. This is the only tax-deferred investment allowed to most individual investors and is the reason primary residence is often the largest single asset in a household's portfolio.
