Real Estate Tax CalcWhat income to track
Every dollar flowing into your rental is potentially taxable. Track rent received (including partial payments, late payments, and advance rent), late fees, lease termination fees, pet fees, parking and storage income, laundry income, and any services tenants pay for that you bill. Record when received, not when earned, if you are a cash-basis taxpayer (most individuals are).
Security deposits are the common exception: do not treat them as income when received. Security deposits are income only if and when you actually keep them for damages or unpaid rent — at that point, record the kept amount as income.
What expenses to track
Deductible operating expenses (reported on Schedule E as current deductions) include: mortgage interest, property taxes, landlord insurance, repairs and ordinary maintenance, property management fees, HOA dues, advertising costs, utilities you pay, professional fees (accounting, legal), and your out-of-pocket mileage to the property at the IRS standard mileage rate (check irs.gov each January for the current year's rate). Capital improvements — new roof, HVAC replacement, major renovation — must be capitalized and depreciated, not expensed immediately. The test: does the expense restore, adapt, or substantially improve the property, or does it simply maintain it in its current condition? Maintenance is currently deductible; improvements are capitalized.
Keep every receipt, invoice, and bank statement. When in doubt, save it.
Tools and practices
A dedicated bank account for your rental makes record-keeping significantly easier — all income and expenses flow through one place, and the annual statement is a ready-made summary. Simple options: a spreadsheet with one row per transaction, with columns for date, description, category, and amount, is adequate for one or two properties. Purpose-built rental property software integrates bank feeds, categorizes expenses automatically, and produces Schedule E-ready reports. Regardless of tool, reconcile monthly so year-end preparation takes hours rather than days.
Track basis, not just this year's numbers
The most valuable — and most neglected — record is your adjusted basis, because it determines your gain and depreciation recapture when you eventually sell, often decades later. From the closing statement, record the purchase price and which closing costs were added to basis, then allocate between land and building (only the building depreciates). Every year thereafter, add the cost of capital improvements to basis and subtract the depreciation you claim. A running basis schedule — start with cost, add improvements, subtract accumulated depreciation — is what lets you (or your accountant) compute the sale correctly and avoid overpaying tax on a phantom gain. Reconstructing basis from scratch at sale, after years of improvements you can no longer document, is one of the most common and costly recordkeeping failures.
Repairs vs. improvements, and the safe harbors
Because misclassifying a cost is easy and consequential, categorize each expense as you record it. A repair (fixing a leak, repainting, replacing a broken appliance part) is deductible now; an improvement (a new roof, an addition, a full HVAC replacement) is capitalized and depreciated. Two elections make this easier and should be made routinely on the return: the de minimis safe harbor lets you expense items costing $2,500 or less per invoice or item, and the small taxpayer safe harbor can let you expense building work up to the lesser of $10,000 or 2% of the building's basis per year. Tagging costs correctly during the year — rather than sorting a shoebox in April — keeps your depreciation schedule accurate and your current deductions defensible.
The 1099 forms landlords deal with
Two information returns commonly touch rental owners. You may receive a Form 1099-K from a booking platform (Airbnb, VRBO), a property manager, or a payment app that processed your rent — reconcile it to your own records, because the gross figure it reports includes amounts (like platform fees) you also get to deduct. You may also be required to issue Form 1099-NEC to unincorporated contractors you pay $600 or more in a year (a handyman, landscaper, or cleaner). Whether a landlord must file 1099s depends on whether the rental rises to a trade or business, but it is required if you claim the QBI rental real estate safe harbor, and many advisors recommend filing them regardless to support your deductions. Collect a Form W-9 from each contractor before you pay them so you have the information ready in January.
A simple month-by-month routine
The habit that makes tax time painless is small and monthly. Each month: (1) record every deposit and categorize it (rent, late fee, deposit withheld); (2) record and categorize every expense, attaching or filing the receipt; (3) flag anything over your de minimis threshold as a possible improvement; (4) reconcile the rental bank account to your ledger; and (5) log any mileage trips. At year end you then only summarize twelve clean months into Schedule E categories, rather than reconstructing a year. Investors who reconcile monthly typically spend an hour or two at tax time; those who don't often spend days and still miss deductions.
How long to keep records
Retain your income and expense records for at least three years after you file the return they support — the general IRS statute of limitations for an audit. Keep them six years if there is any chance you understated income by more than 25%, and indefinitely for any year you did not file. Basis records are different and more important: keep everything documenting purchase price, closing costs, improvements, and depreciation until at least three years after you file the return for the year you sell the property — which could be twenty or thirty years after you bought it. Digital copies (scanned receipts and closing documents) are acceptable and far more durable than fading thermal-paper receipts.
Categorize to match Schedule E as you go
The fastest path to a clean return is to categorize each transaction into the same buckets Schedule E uses, rather than inventing your own labels and re-sorting in April. Set up your ledger or software categories to mirror the form's expense lines: advertising, auto and travel, cleaning and maintenance, commissions, insurance, legal and professional fees, management fees, mortgage interest, repairs, supplies, taxes, utilities, and depreciation, plus an 'other' line with a description. When your bookkeeping categories match the form, transferring the year's totals to Schedule E becomes mechanical, and you are far less likely to bury a deductible cost in a miscellaneous pile or double-count one. Keep depreciation and capital improvements in a separate schedule, since those are computed on Form 4562, not expensed in the operating categories.
Handling mixed-use and personal-use costs
Records get trickier when a cost is only partly for the rental. If you use your car, phone, or home office for both personal life and the rental, you may deduct only the business-use portion, so your records need to establish that percentage — a mileage log for the car, a reasonable allocation for the phone and internet, and square-footage figures for a home office used regularly and exclusively for managing the rentals. For a property with personal use (a vacation home you also rent, or a house hack where you occupy part), expenses must be allocated between rental and personal days, and the vacation-home rules can limit deductions to rental income. Documenting the allocation contemporaneously — days rented versus days used, business miles versus total — is what makes these split deductions survive scrutiny.
Rebuilding records if you've fallen behind
If you have neglected your books, do not give up on the deductions — reconstruct. Start with your bank and credit-card statements, which provide a dated, third-party record of nearly every payment; export a full year and categorize each transaction. Pull the annual mortgage statement for interest and any escrowed taxes and insurance, the property tax bills from the county, and year-end summaries from your property manager or booking platform. Vendors and contractors can usually re-send invoices, and email archives often contain receipts and confirmations. For mileage, a calendar can help you reconstruct trips, though a contemporaneous log is always stronger. Rebuilt records are far better than claiming round numbers or skipping deductions entirely — and the exercise usually surfaces costs you would otherwise have missed. Then set up a monthly routine so you never have to reconstruct a year again.
Frequently asked questions
Are security deposits taxable income?
Not when received. A security deposit is income only in the year you actually keep it — to cover unpaid rent or documented damages. If you return it fully, it was never income.
How do I decide if an expense is deductible now or must be depreciated?
The IRS tangible property regulations use three tests: betterment (does it make the property materially better?), restoration (does it return a major component to working condition?), and adaptation (does it change the use?). If yes to any, capitalize and depreciate. If it is ordinary maintenance keeping the property in its current condition, expense it.
What mileage can I deduct for a rental property?
You can deduct mileage for trips to the property for repairs, inspections, meeting tenants, and management at the IRS standard mileage rate. Keep a contemporaneous log: date, destination, and purpose for every trip.
Do I need to send 1099s to contractors I hire for my rental?
It depends on whether your rental is a trade or business, but you are required to file Form 1099-NEC for unincorporated contractors paid $600 or more if you claim the QBI rental safe harbor, and many advisors recommend filing them in any case. Collect a W-9 from each contractor before paying them.
How long should I keep rental property records?
Keep income and expense records at least three years after filing (six if income may be understated by more than 25%). Keep basis records — purchase, improvements, and depreciation — until at least three years after you file for the year you sell the property.
What is the single most important record to keep?
Your basis schedule. It tracks purchase price plus improvements minus depreciation and determines your taxable gain and recapture at sale. Losing it can cause you to overpay tax on a sale years or decades later.
