Buying a home in Las Vegas unlocks six federal tax benefits that reduce your annual tax bill, often by thousands of dollars. The IRS allows homeowners to deduct mortgage interest, property taxes, and certain improvement costs, and to exclude up to $500,000 in home-sale profits from capital gains. Most buyers do not claim all benefits they qualify for. This guide covers every deduction and credit available in 2026 so you leave nothing on the table.
Key Takeaways
- Homeowners who itemize can deduct mortgage interest on up to $750,000 in loan principal for loans originated after December 16, 2017 (IRS Publication 936).
- State and local tax (SALT) deductions, including property taxes, are capped at $10,000 per year under current law.
- Married couples filing jointly can exclude up to $500,000 in capital gains when selling a primary residence they have owned and occupied for at least two of the last five years.
- The Energy Efficient Home Improvement Credit returns 30% of qualifying upgrade costs, up to $3,200 per tax year.
- The 2025 standard deduction is $15,000 for single filers and $30,000 for married filing jointly, meaning itemizing only beats the standard if your combined deductions exceed those thresholds.
The Mortgage Interest Deduction Cuts Your Taxable Income From Day One
Homeowners with a mortgage on a primary or qualified second residence can deduct every dollar of interest paid during the tax year on loan balances up to $750,000, or up to $1 million for loans originated before December 17, 2017. On a $500,000 mortgage at 7% interest, a borrower pays roughly $34,700 in interest during year one, creating a substantial itemized deduction. Source: IRS Publication 936.
To claim this deduction, your lender issues Form 1098 in January showing the exact interest paid. You enter that figure on Schedule A of your federal return. The deduction is available for mortgages on single-family homes, condos, co-ops, mobile homes, and houseboats, provided the property secures the loan. Home equity loan interest also qualifies when the proceeds are used to buy, build, or substantially improve the home.
Citation: According to IRS Publication 936, mortgage interest deductibility is limited to $750,000 of qualified loan principal for mortgages originated after December 16, 2017. For a borrower in the 22% tax bracket carrying $500,000 in mortgage debt at 7%, the first-year deduction reduces federal taxes owed by roughly $7,634.
One important trade-off: you must itemize deductions on Schedule A rather than taking the standard deduction. For 2025 tax returns, the standard deduction is $15,000 for single filers and $30,000 for married filing jointly. If your mortgage interest alone approaches or exceeds those thresholds when combined with other deductions, itemizing delivers more savings. Your closing cost breakdown includes prepaid interest, which is also deductible in the year you close. Read more in our related guide: tax deductions for home buyers.
Mortgage points paid at closing to reduce your interest rate are also deductible. Points paid to purchase a primary residence are generally fully deductible in the year of purchase, while points paid on a refinance must be deducted over the life of the loan. See our complete guide to mortgage points for the full breakdown.
The Property Tax Deduction Is Capped at $10,000 Under Current SALT Rules
Homeowners can deduct state and local taxes (SALT), including property taxes paid on a primary residence, up to $10,000 per year ($5,000 if married filing separately) under the Tax Cuts and Jobs Act. Nevada has no state income tax, so Las Vegas homeowners apply the full $10,000 cap exclusively to property taxes, making this deduction highly accessible in our market. Source: IRS Topic No. 503.
Nevada’s property tax rate averages 0.53%, one of the lowest in the nation. On a $450,000 Las Vegas home, the annual property tax bill is roughly $2,385, well within the $10,000 SALT cap. That means most Las Vegas buyers can deduct 100% of their property taxes without hitting the ceiling.
Citation: According to IRS Topic No. 503, deductible real estate taxes are any state, local, or foreign taxes imposed for the general public welfare. Taxes assessed for local benefits like sidewalks or sewers are not deductible. Property taxes paid at closing and those escrowed by your lender both qualify in the year they are actually paid to the taxing authority.
You can also deduct property taxes paid at closing, which your closing disclosure will itemize separately. If you have an impound/escrow account, your lender pays the taxes on your behalf; the amount paid to the taxing authority during the calendar year is what counts as your deduction, not what you deposited into the escrow account.
Understanding the full scope of tax deductions available to buyers and sellers ensures you capture every dollar your closing generates.
The Capital Gains Exclusion Shelters Up to $500,000 in Home Sale Profits
When you sell a home you have owned and lived in as a primary residence for at least two of the last five years, you can exclude up to $250,000 in capital gains from taxable income ($500,000 for married couples filing jointly). This is arguably the most valuable tax benefit tied to homeownership. For Las Vegas, where median home prices rose from $280,000 in 2020 to over $430,000 by early 2026, many sellers qualify for a full exclusion. Source: IRS Publication 523.
The two-year ownership and use tests do not need to be met consecutively. You can have moved out and returned, or temporarily rented the home, as long as you meet the cumulative two-year threshold within the five-year lookback period. Partial exclusions apply if you had to sell early due to a job change, health event, or unforeseen circumstance.
Citation: According to IRS Publication 523, taxpayers who do not meet the full ownership and use tests may still qualify for a reduced exclusion based on the fraction of the two-year period they did meet. This provision is especially relevant for Las Vegas buyers who relocate due to job transfers or family changes within the first two years of ownership.
Capital improvements you make during ownership, such as a kitchen remodel, new roof, or pool addition, increase your cost basis and further reduce the taxable gain. Keep receipts for all improvements. Selling expenses like agent commissions, title fees, and transfer taxes also reduce your net gain dollar for dollar. Review the capital gains tax guide for home sellers before listing your property.
Energy Tax Credits Return 30% of Qualifying Home Improvement Costs
The Energy Efficient Home Improvement Credit (IRS Form 5695) lets homeowners claim 30% of the cost of qualifying upgrades, up to $3,200 per year: up to $1,200 for most improvements and up to $2,000 for heat pumps and heat pump water heaters. The Residential Clean Energy Credit covers 30% of solar panel installation with no annual dollar cap and runs through 2032. Source: IRS Form 5695 instructions.
Unlike deductions, credits reduce your tax bill dollar for dollar. If you spend $10,000 on a qualifying solar system, a 30% credit puts $3,000 directly back into your pocket regardless of your tax bracket. In Las Vegas, where summer cooling costs are extreme, heat pump upgrades (up to $2,000 credit) and enhanced insulation or Energy Star windows (up to $600 credit each) are among the most cost-effective investments.
Citation: According to the IRS instructions for Form 5695, the Energy Efficient Home Improvement Credit resets annually, meaning homeowners can claim up to $3,200 each tax year for different qualifying improvements spread over multiple years. Solar installations qualify for the separate Residential Clean Energy Credit at 30% with no cap, providing significant savings for Las Vegas buyers given the region’s 300-plus annual days of sunshine.
Qualifying improvements include: insulation, air sealing, exterior doors (up to $500 limit), exterior windows and skylights (up to $600), heat pumps, heat pump water heaters, central air conditioners, biomass stoves, and home energy audits (up to $150). Products must meet Energy Star or other IRS-specified performance standards.
The Home Office Deduction Is Available to Self-Employed Homeowners
Self-employed buyers who use a portion of their home exclusively and regularly for business can deduct home office costs. The simplified method allows $5 per square foot up to 300 square feet, for a maximum $1,500 annual deduction. The regular method deducts actual costs proportional to the office’s share of total home square footage, which includes mortgage interest, utilities, insurance, and depreciation. Source: IRS Publication 587.
The exclusive-use test is strict: a room used for both work and personal activities does not qualify. However, a clearly dedicated workspace, even a partitioned section of a room, can qualify if it meets the regular and exclusive use standard. W-2 employees cannot claim this deduction under current law.
Citation: According to IRS Publication 587, the home office deduction under the regular method requires calculating the percentage of your home used for business, then applying that percentage to total home expenses. A 200-square-foot office in a 2,000-square-foot Las Vegas home represents 10%, allowing deduction of 10% of mortgage interest, property taxes, utilities, and repairs in addition to the standard itemized deductions already claimed.
For homeowners with significant home expenses, the regular method often outperforms the simplified method. An accountant or tax software can run both calculations to determine which maximizes your refund. If you use the regular method, note that the portion of depreciation claimed on the home office reduces your cost basis and may create a small taxable gain on sale.
Itemizing Beats the Standard Deduction When Your Deductions Cross the Threshold
The 2025 standard deduction is $15,000 for single filers and $30,000 for married filing jointly. For most Las Vegas first-time buyers, mortgage interest alone often falls below the single-filer threshold, but combining mortgage interest, property taxes, and any other deductions frequently pushes married couples over $30,000, making itemizing worthwhile.

Run a side-by-side calculation every year. In the early years of a mortgage when interest is highest, itemizing often wins. As the loan matures and more of each payment goes toward principal rather than interest, the standard deduction may become more advantageous.
Key itemizable expenses beyond mortgage interest and property taxes include: charitable contributions, unreimbursed medical expenses exceeding 7.5% of adjusted gross income, mortgage points (in the year of purchase for a primary home), and mortgage insurance premiums. Adding each eligible deduction on top of a large mortgage interest deduction frequently makes itemizing the better option for active buyers in the Las Vegas market.
Understanding buyer agent fees and how they factor into your purchase costs helps clarify what portion of your closing transaction may have tax implications. Similarly, first-time buyers using down payment assistance programs should confirm with a tax professional whether any grant amounts affect their basis or qualify as income.

What Las Vegas Buyers Should Do Before Filing
- Collect Form 1098 from your lender showing mortgage interest paid.
- Gather property tax payment records from Clark County or your escrow statement.
- Compile receipts for any energy-efficient improvements completed during the tax year.
- Calculate the square footage of any dedicated home office space.
- Run a Schedule A itemized total and compare it to the standard deduction before filing.
Working with a CPA familiar with Nevada tax law maximizes your return. Nevada’s lack of state income tax means your SALT deduction is applied entirely to property taxes, a simpler calculation than in high-income-tax states. Buyers who used real estate commissions paid at closing should note those are added to cost basis, not deducted in the purchase year. Read more in our related guide: real estate trust options.

Frequently Asked Questions
Can I deduct mortgage interest on a Las Vegas investment property?
Yes, but as a rental expense on Schedule E rather than an itemized deduction on Schedule A. Investment property interest is not subject to the $750,000 cap. It offsets rental income directly, reducing taxable net rental income.
Does Nevada’s lack of state income tax affect my SALT deduction?
It works in your favor. The entire $10,000 SALT cap goes toward property taxes rather than being consumed by state income taxes. Las Vegas homeowners typically maximize this deduction more easily than buyers in high-income-tax states. Explore further in our green homes las vegas.
How long must I live in my home to qualify for the capital gains exclusion?
Two of the five years immediately before the sale, and those two years do not need to be consecutive. Partial exclusions are available if you sold early due to a job relocation, health issue, or unforeseen circumstance.
What energy improvements qualify for the 30% federal tax credit in 2026?
Solar panels (no cap via Residential Clean Energy Credit), heat pumps and heat pump water heaters (up to $2,000), insulation, Energy Star windows and doors, qualifying central air conditioners, and home energy audits. The annual cap for non-solar improvements is $3,200.
Is mortgage interest deductible after a refinance?
Yes, up to the same $750,000 principal limit. Points paid on a refinance must be amortized over the loan term rather than deducted in full in the year of closing, unlike points paid on an original purchase mortgage.
