Homeowners who itemize deductions save an average of $3,000 more per year than those who miss key forms, according to IRS Statistics of Income data. For Las Vegas landlords and owner-occupants alike, knowing exactly which tax documents to collect – and where to get them – is the difference between a refund and a costly miss.
Key Takeaways
- Form 1098 reports mortgage interest paid – the most commonly missed deduction for homeowners who itemize.
- Landlords must report rental income on Schedule E and can deduct operating expenses, depreciation, and mortgage interest against that income.
- The IRS allows up to a $250,000 ($500,000 married filing jointly) capital gains exclusion on a primary home sale – but Form 1099-S must still be reviewed.
- Nevada has no state income tax, so Las Vegas landlords file only federally – simplifying but not eliminating the document burden.
- Keep all supporting records at least three years from the filing date; six years if income was underreported by more than 25%.
Form 1098 Unlocks the Mortgage Interest Deduction for Most Homeowners
For homeowners with a mortgage, Form 1098 is the single most valuable tax document they receive each year. Lenders must mail it by January 31. It shows total mortgage interest paid, any points paid at closing, and mortgage insurance premiums – all potentially deductible if you itemize on Schedule A.
Citation: The IRS Publication 936 confirms that mortgage interest on loans up to $750,000 (for loans originated after December 15, 2017) is fully deductible for taxpayers who itemize. For older loans the limit is $1 million. Points paid to obtain the mortgage are generally deductible in the year paid on a primary home purchase. Taxpayers who do not itemize receive no benefit from Form 1098 – the standard deduction for 2026 is $15,000 (single) and $30,000 (married filing jointly) per IRS Rev. Proc. 2025-28.
What to do with it: Enter Box 1 (mortgage interest) on Schedule A, line 8a. If you paid points (Box 6), those go on line 8a as well. If any amount was refunded (Box 4), subtract it. Landlords who hold a mortgage on a rental unit use Form 1098 differently – the interest goes on Schedule E, not Schedule A, as a rental operating expense.
Landlords Need Schedule E – Not Just Schedule A
Owner-occupants report deductions on Schedule A. Rental property owners report income and expenses on Schedule E (Supplemental Income and Loss). This is the most important distinction in landlord tax filing.
Schedule E captures all rental income received and subtracts allowable operating expenses: mortgage interest, property taxes, insurance premiums, repairs and maintenance, property management fees, and depreciation. Net rental income flows to Form 1040; net rental losses may be deductible depending on your income level and passive activity rules.
Citation: IRS Publication 527 – Residential Rental Property – is the authoritative guide for landlords. It covers what income to report, which expenses are deductible, depreciation of residential rental property (27.5-year straight-line), and passive activity loss rules under IRC Section 469. The IRS notes that landlords with adjusted gross income under $100,000 may deduct up to $25,000 in rental losses if they actively participate in managing the property.
Documents Schedule E requires you to have:
- Form 1098 (mortgage interest on the rental)
- Property tax statement for the rental address
- Property management fee invoices (fully deductible)
- Insurance premium statements (see landlord insurance Nevada)
- Repair and maintenance receipts (not capital improvements – those go on Form 4562 as depreciation)
- Security deposit records if any were applied to damages (Nevada security deposit rules)
Form 1099-S and the Capital Gains Exclusion on Home Sales
When you sell a home, the title or escrow company may file Form 1099-S with the IRS and send you a copy. This form reports the gross proceeds of the sale. Even if you qualify for the full capital gains exclusion, you may still receive the form – and you should still review it.
For a primary residence, the IRS allows sellers to exclude up to $250,000 in capital gain ($500,000 married filing jointly) under IRC Section 121, provided the home was the primary residence for at least two of the five years before the sale. If your gain exceeds the exclusion or the property was a rental, the taxable portion reports on Form 8949 and flows to Schedule D.
Your adjusted basis matters here. Basis starts at the purchase price (from your Closing Disclosure) plus closing costs capitalized at purchase, plus the cost of capital improvements made during ownership. Subtracting basis from sale proceeds gives you your realized gain. Missing improvement receipts means a higher taxable gain – which is why a 6-year receipt archive is worth keeping.
For Las Vegas landlords who convert a rental to a primary residence, a blended calculation applies: the exclusion applies only to periods of primary residence use, and depreciation claimed during rental use must be recaptured as ordinary income (Section 1250 recapture, taxed at up to 25%).

Property Tax Statements and the SALT Deduction Cap
Nevada’s Clark County Assessor mails property tax statements annually. For owner-occupants who itemize, property taxes paid are deductible on Schedule A – but only up to the $10,000 State and Local Tax (SALT) cap established by the Tax Cuts and Jobs Act of 2017, which remains in effect for 2026 under current law.
Because Nevada has no state income tax, Las Vegas homeowners’ entire $10,000 SALT cap is available for property taxes – an advantage over homeowners in high-income-tax states who exhaust the cap on income taxes alone.
Citation: The IRS SALT deduction guidance (Topic 503) confirms the $10,000 cap applies to the combined total of state and local income taxes plus real property taxes. Nevada’s zero income tax rate means more of the cap is available for Clark County property taxes. The Clark County Treasurer’s online portal allows homeowners to print official property tax paid records at no cost.
For rental property: There is no SALT cap on rental property taxes. The full amount paid is deductible on Schedule E as an operating expense, making accurate property tax statements critical for landlords evaluating their cash flow from rental property.
Form 5695: Residential Clean Energy and Energy Efficiency Credits
Form 5695 captures two separate credits:
Residential Clean Energy Credit (Part I): A 30% credit for solar panels, solar water heaters, wind turbines, geothermal heat pumps, and battery storage systems installed through 2032. The credit applies against federal tax owed, dollar for dollar. Unused credit carries forward. The 30% rate was extended by the Inflation Reduction Act.
Energy Efficient Home Improvement Credit (Part II): A credit of up to $3,200 per year for qualifying upgrades including insulation, exterior windows, exterior doors, and heat pumps. Individual sub-limits apply ($600 for windows, $500 for doors, etc.).
Citation: IRS Form 5695 Instructions (2025) detail exactly which products qualify and the documentation required. The IRS requires manufacturers’ certification statements proving the product meets efficiency standards – these are typically available on the manufacturer’s website or included in product documentation. Without this certification, the credit may be disallowed on audit.
Note: These credits apply only to the taxpayer’s primary residence (or second home in some cases). Rental property improvements do not qualify for Form 5695 credits – they are instead recovered through depreciation on Schedule E.
Closing Disclosures, HUD-1s, and Your Cost Basis
The Closing Disclosure (or HUD-1 for older transactions) is the master ledger of your real estate transaction. It shows purchase price, loan amount, prepaid interest, prorated property taxes, title insurance, and all closing costs. For tax purposes, it serves two functions:
At purchase: Certain closing costs – prepaid property taxes, prepaid interest, and loan origination points – may be deductible in the year of purchase. Other costs add to your cost basis (title insurance, recording fees, transfer taxes paid by buyer).
At sale: Your adjusted basis calculation starts with the original purchase price shown on the closing disclosure. Every capital improvement receipt collected over the ownership period adds to that basis, reducing the taxable gain when you eventually sell.
Las Vegas investors using the 1031 exchange to defer capital gains must track basis across properties – the Closing Disclosure from each transaction becomes a permanent record, not something to discard after three years.
Retain your Closing Disclosure permanently (or at least six years after selling the property).
Form 4562 and Rental Property Depreciation
Depreciation is one of the most powerful tax benefits available to rental property owners – and it requires Form 4562. Residential rental property depreciates over 27.5 years using the straight-line method. For a property with a $300,000 depreciable basis (land value excluded), that yields approximately $10,909 per year in depreciation expense, deductible on Schedule E even if the property generates positive cash flow.
To calculate depreciation correctly you need:
- Purchase price (from Closing Disclosure)
- Land value (from county assessor or appraisal)
- Date placed in service
- Cost of any capital improvements (each improvement depreciates separately from its own placed-in-service date)
This is the area where a CPA familiar with rental property is most valuable. Errors in depreciation calculations create recapture exposure at sale and potential underpayment penalties.
Citation: IRS Publication 946 – How to Depreciate Property – is the definitive guide. It covers MACRS depreciation, bonus depreciation rules (phased down from 100% through 2026), and Section 179 elections (which generally do not apply to residential rental property).
Document Retention Checklist for Las Vegas Homeowners and Landlords
Knowing which documents to keep – and for how long – prevents audit exposure:
| Document | Retention Period |
|---|---|
| Form 1098 (mortgage interest) | 3 years from filing |
| Schedule E with supporting receipts | 3 years from filing |
| Property tax statements | 3 years from filing |
| Capital improvement receipts | Life of property + 6 years |
| Closing Disclosure (purchase) | Life of property + 6 years |
| Depreciation schedules (Form 4562) | Life of property + 6 years |
| Form 1099-S (sale proceeds) | 6 years from sale |
| Rental agreements (signed leases) | 3 years after lease ends |
Nevada landlords managing their own properties may find it useful to review the rent increase laws Nevada and landlord eviction process Nevada alongside tax records – legal documentation often overlaps with tax documentation in landlord-tenant disputes.
Additional Documents Landlords Should Collect
Beyond the standard homeowner forms, rental property investors need:
- Rental income ledger: A running record of rent received by unit and by month. The IRS requires all rental income to be reported regardless of whether a 1099 is issued.
- Security deposit accounting: Deposits held are not income. When applied to damages, the amount applied becomes income (offset by the repair cost as an expense). Proper records prevent double taxation. Nevada’s security deposit laws add another reason to track this carefully.
- Tenant payment records: Documentation of late fees collected (taxable income) and any rent concessions given.
- Professional service invoices: Property management fees, legal fees for eviction proceedings, accounting fees – all deductible on Schedule E. Rental property insurance premiums also belong here.
- Mileage log: If you drive to inspect the property, make repairs, or meet contractors, mileage may be deductible. The IRS standard mileage rate for 2026 is set annually in December.
For investors tracking multiple metrics, organizing these records by property makes calculating cap rate, cash-on-cash return, and overall portfolio performance much faster at year end.

Frequently Asked Questions
What is the most important tax document for a homeowner with a mortgage?
Form 1098 is the most important. Your mortgage lender sends it by January 31 each year. It reports the total mortgage interest you paid, which is deductible on Schedule A if you itemize. For 2026, the standard deduction is $15,000 (single) or $30,000 (married filing jointly) – you only benefit from itemizing if your total deductions exceed these amounts.
What tax form do Las Vegas landlords use to report rental income?
Landlords use Schedule E (Supplemental Income and Loss), attached to Form 1040. Schedule E reports all rental income received and deducts operating expenses including mortgage interest, property taxes, insurance, repairs, property management fees, and depreciation. Net income or loss flows to Form 1040. Depreciation is calculated separately on Form 4562.
Do I have to pay capital gains tax when I sell my Las Vegas home?
Not necessarily. Under IRC Section 121, you can exclude up to $250,000 of capital gain ($500,000 married filing jointly) if the home was your primary residence for at least 2 of the 5 years before the sale. However, any depreciation claimed during rental use must be recaptured as ordinary income regardless of the exclusion. You still need to review Form 1099-S and calculate your adjusted basis to confirm no taxable gain exists.
Can Nevada landlords deduct property taxes on rental properties without the $10,000 SALT cap?
Yes. The SALT cap applies only to Schedule A personal itemized deductions. Property taxes on a rental property are deducted as a business expense on Schedule E and are not subject to the SALT cap – the full amount paid is deductible.
How long should I keep rental property tax documents?
Keep annual returns and supporting documents at least 3 years from the filing date. Keep capital improvement receipts, depreciation schedules, and your original Closing Disclosure for the life of the property plus 6 years after sale – these records affect your basis calculation and potential depreciation recapture at sale.
