Every Tax Benefit Los Angeles Homeowners Should Know About Before April 15

Tax season is here, and if you own a home in Los Angeles, you may be sitting on deductions and credits worth thousands of dollars — some of which changed significantly for 2025 returns.

The 2025 tax year brought meaningful updates for homeowners, including a dramatically expanded SALT deduction that is especially relevant for California property owners, the restoration of the PMI deduction, and the final year to claim certain energy efficiency credits. If you're filing between now and April 15, this guide covers every major tax benefit available to homeowners — what's changed, what the limits are, and what you need to do to claim them.

First: Should You Itemize or Take the Standard Deduction?

Before any of the deductions below apply to you, you need to decide whether itemizing makes sense. The standard deduction for 2025 is $15,750 for single filers and $31,500 for married couples filing jointly.

Itemizing only makes financial sense if the sum of your deductible expenses exceeds those thresholds. For many LA homeowners — especially those with large mortgages and high property tax bills — itemizing is absolutely worth running the numbers on. If you have a large, high-interest mortgage and live in a high property tax area, you could potentially get a significant boost from itemizing.

Here's the quick test: add up your mortgage interest, property taxes, and any other eligible deductions listed below. If that total exceeds $15,750 (single) or $31,500 (married), you should itemize. If not, the standard deduction is simpler and may be larger.

1. Mortgage Interest Deduction

This is typically the largest tax benefit available to homeowners and one of the primary reasons ownership builds long-term wealth advantages over renting.

You can deduct the interest you pay on your mortgage for your primary residence and a second home, up to certain limits. Filers can deduct up to $750,000 of mortgage debt, or up to $375,000 for married people who file separately.

What this means for LA homeowners: Given that the median home price in many Westside neighborhoods exceeds $1 million, and most buyers are carrying substantial mortgages, the interest deduction on a $750,000 loan at current rates can represent a significant annual deduction. In the early years of a mortgage — when interest makes up the largest share of each payment — this benefit is at its maximum.

Look for Form 1098. Your mortgage interest statement for 2025 should have been provided or sent to you by January 31, 2026. This form shows exactly how much interest you paid and is what you'll use to claim the deduction on Schedule A.

Grandfathered loans: Homeowners with mortgage debt taken out before December 16, 2017 may be eligible for the prior-law $1 million limit rather than the current $750,000 cap. If you've owned your home for several years, it's worth checking which limit applies to you.

2. Property Tax Deduction — SALT Cap Dramatically Expanded for 2025

This is the change that will matter most to California homeowners filing 2025 taxes.

The old SALT (State and Local Tax) deduction cap was $10,000 — a threshold that was routinely hit by Los Angeles homeowners in a single property tax payment. Under the "One Big Beautiful Bill" passed in 2025, the SALT deduction limit has been increased to $40,000 ($20,000 for married individuals filing separately) for 2025 through 2029, with 1% annual inflation adjustments.

For the 2025 tax year, you may deduct up to $40,000 (or $20,000 if married filing separately) of property taxes in combination with state and local income taxes or sales taxes.

Why this is significant for LA owners: California has both high income tax rates and substantial property tax bills. For years, the $10,000 SALT cap effectively eliminated a meaningful deduction for middle-to-upper-income California homeowners. The new $40,000 cap restores a significant portion of that deductibility. If your combined state income taxes and property taxes were previously well above $10,000 — which is common for Westside homeowners — this change meaningfully improves your tax position for 2025.

Income phaseout to know: The higher SALT limit begins to phase out for taxpayers with modified adjusted gross income over $500,000 ($250,000 for married individuals filing separately), reducing the allowable deduction by 30% of MAGI above the threshold, but not below $10,000.

3. Home Equity Loan and HELOC Interest

If you took out a home equity loan or HELOC in 2025, the interest may be deductible — but the use of the funds matters enormously.

Homeowners can deduct interest on total combined mortgage debt, including primary mortgage and HELOC, up to $750,000 — but only if the HELOC funds were used to buy, build, or substantially improve the home securing the loan. If HELOC funds were used for personal expenses, such as paying off credit card debt, the interest is not deductible.

In practical terms: if you used a HELOC to renovate your kitchen, add square footage, or make structural improvements, the interest is likely deductible. If you used it to pay for a vacation or consolidate other debt, it's not. Keep records of how the funds were spent.

4. Discount Points

Mortgage discount points are fees paid to lenders at closing for the purpose of reducing a loan's interest rate. Points paid on a home purchase loan are fully deductible in the year of payment if they meet IRS requirements. If refinancing a mortgage, discount points must be deducted over the life of the loan rather than in a single year.

If you purchased a home in 2025 and paid points to buy down your rate — a strategy many buyers used to manage high interest rates — those points are fully deductible on your 2025 return.

5. PMI Deduction — Restored for 2026

Starting in 2026, the One Big Beautiful Bill allows deductions for private mortgage insurance (PMI) premiums. This deduction had expired and was not available for 2024 returns. If you pay PMI on your loan, this is newly available for your 2025 taxes — check with your tax professional to confirm eligibility for your specific situation.

6. Energy Efficiency Credits — Last Year to Claim

This one comes with an important deadline caveat.

The elimination of energy-focused home improvement tax credits took effect at the end of 2025 under the "One Big Beautiful Bill." To qualify for the credits this tax season, homeowners must have completed their energy upgrades in 2025 — not just purchased the items, but had the work completed by December 31, 2025.

If you installed solar panels, energy-efficient windows, a heat pump, upgraded insulation, or made other qualifying improvements last year and the work was completed before December 31, 2025, you may still claim these credits on your 2025 return. Solar and certain energy improvements may qualify for federal tax credits of 30% of the cost.

If the work wasn't completed by year-end, the credit is no longer available for future years under current law.

7. Home Office Deduction

If you're self-employed and work from home — common among the freelancers, creatives, and entrepreneurs that make up a significant portion of the Westside workforce — the home office deduction can be substantial.

If you use part of your home exclusively and regularly for your business, you may be able to deduct a portion of your home expenses, including mortgage interest, insurance, utilities, and repairs.

The key requirements: the space must be used exclusively for business (a desk in your bedroom doesn't qualify — a dedicated room does) and regularly throughout the year. Remote employees generally don't qualify for this deduction — it applies to self-employed individuals and business owners only.

8. Capital Gains Exclusion When You Sell

This benefit applies when you sell, not when you file — but it's worth understanding now, especially if you're thinking about listing your home in 2025 or 2026.

When you sell your home, you can exclude up to $250,000 of the profit ($500,000 for a married couple filing jointly) from capital gains tax, as long as you have owned and lived in the home for at least two of the five years before the sale.

For Los Angeles homeowners who've held property through the appreciation of the past decade, this exclusion is one of the most powerful wealth-building tools in the tax code. On a home purchased for $900,000 and sold for $1,600,000 after significant appreciation, a married couple could exclude the entire $700,000 gain from taxation — provided they meet the two-year occupancy requirement.

Keep receipts for improvements — they increase your cost basis and reduce taxable capital gains when you sell. Every dollar you've spent on permitted additions, significant renovations, or improvements to your property can be added to your cost basis, reducing the gain that's subject to tax.

9. Medical-Related Home Improvements

If you make improvements to your home for medical reasons — such as installing an entrance ramp or modifying a bathroom for accessibility — you may be able to deduct the costs as a medical expense. These deductions apply when the costs exceed 7.5% of adjusted gross income and the improvements don't increase the home's market value.

What Documents You Need to File

Get these together before you sit down with your tax professional or tax software:

• Form 1098 — mortgage interest statement from your lender (should have arrived by January 31)
• Property tax payment records — your county tax bills or escrow account statements showing what was paid in 2025
• Closing disclosure — if you purchased a home in 2025, this shows points paid and other deductible closing costs
• HELOC or home equity loan statements — showing interest paid, plus documentation of how funds were used
• Receipts for home improvements — especially energy efficiency upgrades completed in 2025
• Prior year tax return — helpful for basis calculations if you're planning to sell

Note that mortgage interest and property taxes are deductible only in the year the payment is actually sent to the lender or tax authority. If you pay property taxes through an escrow account, you cannot deduct the amount when it's deposited into escrow — only when the payment is actually disbursed to the county.

A Note on the Itemize vs. Standard Decision for LA Homeowners

Given the combination of high mortgage balances, high property taxes, and high state income taxes in California, LA homeowners are among the most likely in the country to benefit from itemizing — particularly now that the SALT cap has been raised to $40,000.

If your mortgage interest alone exceeds the standard deduction threshold, itemizing is almost certainly worth it. If your mortgage interest plus property taxes plus state income taxes (up to $40,000) plus any other eligible deductions pushes you well above the standard deduction, the difference can translate into thousands of dollars in tax savings.

Running this calculation with a tax professional before filing is one of the most straightforward ways to make sure you're not leaving money on the table.

Thinking About Buying or Selling in 2026?

The tax benefits of homeownership extend well beyond filing season. The mortgage interest deduction, the property tax deduction, and especially the capital gains exclusion on sale are structural financial advantages that compound over time — and that renters simply don't have access to.
