Year-End Tax Document Checklist for Landlords (2026)

TL;DR: Before January, gather income documents (1099s, rent ledgers, K-1s), mortgage/interest statements (Form 1098), property tax and insurance statements, and expense summaries. Organize totals by category, attach depreciation schedules, and hand your CPA clean records instead of raw receipts. A short checklist run every December saves phone-tag in March.

You've kept receipts all year and logged expenses as you paid them. Now it's mid-December and your CPA wants a full year of rental property records by mid-January. A year-end tax document checklist tells you exactly which forms to pull, which summaries to build, and which numbers to confirm before you hand anything over.

Okoniq Property Hub stores receipts, logs expenses by category, and generates year-end summaries so you're not reconstructing January's water bill in March.

What income documents does my CPA need for rental property?

Everything that reports income to the IRS goes in the first pile. Start with Form 1099-NEC or 1099-MISC if you received payments as an independent contractor or for services rendered. For rental properties, you typically don't receive a 1099 for tenant rent — rental income is self-reported — but if you sold a property during the year, look for Form 1099-S, which reports the gross proceeds and is sent to you and the IRS.

If you hold rental property through an LLC taxed as a partnership or an S corporation, you'll receive Schedule K-1 showing your share of income, deductions, and credits. K-1s often arrive late (March or April), so tell your CPA in January if you're waiting on one. If you had W-2 wages from a separate job, include that form as well — your rental losses may offset W-2 income depending on your real estate professional status or the $25,000 passive loss allowance.

Your rent ledger — a month-by-month summary of collected rent, late fees, and any concessions — completes the income picture. Your CPA needs the total annual rent collected, not twelve separate deposit slips. List security deposits you returned during the year separately; refunded deposits are not income.

What mortgage and interest statements do I need?

Form 1098 reports the mortgage interest you paid during the year and is mailed by your lender in January. If you paid more than one loan (primary residence mortgage plus rental property mortgage), you'll receive a 1098 for each. The interest paid on a rental property mortgage is deductible in full on Schedule E, unlike the mortgage interest deduction on a primary residence, which has dollar-amount limitations.

If you refinanced during the year, you may have paid points or origination fees. Some of those costs are deductible over the life of the loan; others are deductible in the year paid. Attach the closing statement from the refinance so your CPA can allocate the deduction correctly. If you took a home equity line of credit and used the proceeds for rental property repairs or improvements, include the year-end statement showing interest paid — it's deductible if the loan was used for business purposes.

Private loans or seller financing won't generate a 1098, but the interest is still deductible. Summarize the interest paid in a simple spreadsheet (date, payee, amount) and attach proof of payment.

Are property tax and insurance statements deductible?

Property tax bills and homeowner's insurance premiums are deductible on Schedule E, but only if the property is used as a rental. If you lived in the property for part of the year before converting it to a rental, only the portion of the year it was available for rent counts. Your property tax bill — typically mailed once or twice a year by your county assessor — states the annual amount due. If you paid through an escrow account, the 1098 may already include property taxes paid; check the form before summarizing twice.

Homeowner's insurance (fire, liability, flood if required) is deductible. Landlord liability policies and umbrella policies are deductible too. Pull the declaration page from each policy showing the premium paid and the coverage period. If you appealed your property tax and won a reduction, attach the appeal decision letter — the deduction is the amount you actually paid, not the assessed value.

Condo or HOA fees paid on a rental property are deductible as operating expenses. Include the year-end statement showing the total paid. Special assessments for capital improvements (new roof, elevator) may need to be capitalized rather than deducted in one year — attach the assessment notice so your CPA can decide.

What expense summaries and depreciation schedules should I prepare?

Your CPA doesn't want a shoebox of receipts. They want expense totals by category: repairs and maintenance, utilities, advertising, property management fees, legal and professional fees, travel and mileage, supplies, and any other ordinary and necessary costs. Okoniq Property Hub groups expenses by IRS category and generates a year-end summary you can export directly.

Separate repairs from improvements. A repair restores the property to its previous condition (patch a leak, replace a broken window). An improvement adds value or extends the property's life (new roof, HVAC replacement) and must be depreciated over multiple years. If you paid a contractor more than the current 1099-NEC threshold for the year, note that — you may owe a 1099. For payments made in 2025, the threshold is $600. For payments made on or after January 1, 2026, the threshold rises to $2,000 under the One Big Beautiful Bill. Confirm the threshold that applies to your tax year on IRS.gov.

Attach the prior year's depreciation schedule if you took depreciation in earlier years. The schedule lists the property's cost basis, the date it was placed in service, the depreciation method (typically straight-line over 27.5 years for residential rental property), and the accumulated depreciation to date. If you used cost segregation or bonus depreciation, note that on the schedule. Your CPA needs this to calculate current-year depreciation and to track recapture when you sell.

If you have a home office used regularly and exclusively for rental property management, summarize the square footage and percentage of your home's total area. Attach utility bills and home insurance premiums — a portion is deductible based on the percentage. If you drove to the property for repairs, showings, or inspections, provide a mileage log with dates, destinations, and business purpose.

Should I run the same checklist every December?

Yes. A year-end checklist you repeat every December catches missing documents before January, when CPAs are swamped. Start by confirming you have a 1098 for every mortgage, a rent ledger that matches your bank deposits, and property tax bills for every property you own. Export expense totals from your accounting software or property management app and reconcile them against your bank statements — a $200 difference in December is easy to find; in March it's three emails and a phone call.

If you made estimated tax payments during the year, pull the confirmation receipts or your IRS account transcript. Overpayments can be credited to the following year; underpayments may trigger a penalty. If you qualify for the $25,000 passive loss allowance or the QBI deduction, gather the income and AGI figures your CPA needs to determine eligibility.

Create a folder (physical or digital) labeled "Tax Year 2026" and drop every document into it as you receive it. By mid-January, you'll have a complete packet ready to hand over, and your CPA won't be texting you in March asking where the 1098 went.

FAQ

Do I need to give my CPA every receipt for every repair?

No. Summarize expenses by category (repairs, utilities, management fees) and attach the totals. Keep receipts in your files in case the IRS asks, but most CPAs prefer clean summaries over raw receipts.

What if I'm still waiting on a K-1 in January?

Tell your CPA immediately. K-1s often arrive late, and they may file an extension or prepare a draft return. Don't wait until April to mention it.

Can I deduct property taxes if I paid them through escrow?

Yes. The 1098 from your lender typically shows the property taxes paid from escrow during the year. Check that line before summarizing separately.

Do I need a depreciation schedule if this is my first year renting the property?

Yes. Your CPA will create one, but you need to provide the property's purchase price, closing costs, and the date you first made it available for rent. If you converted a primary residence, attach the date you moved out.

What happens if I forget to report a 1099-S from a property sale?

The IRS already received a copy. If you don't report the sale, they'll send a notice. Include every 1099 you receive, even if you think the gain is excluded under Section 121 or a 1031 exchange deferred it.
