Landlord Bookkeeping: How to Track Income & Expenses for Tax Time
A simple system that captures every deduction, survives an audit, and takes ten minutes a week to maintain.
The difference between landlords who keep most of their cash flow and landlords who hand it to the IRS is bookkeeping. Every legitimate expense you can document reduces taxable income. Every receipt you lose, every mileage trip you don't log, every cash payment you don't reconcile — that's after-tax money walking out the door.
The good news: rental bookkeeping is simpler than business bookkeeping. There are about 15 expense categories total, the IRS gives you a specific form (Schedule E) that maps to those categories, and a single hour per month of discipline keeps you audit-ready year-round.
The foundation: separate accounts
The single most important decision is segregating rental finances from personal finances. Open a dedicated checking account for rental income and expenses. If you have multiple properties, ideally one account per property — or one account per LLC if you've structured them that way (see our LLC setup guide).
Why separation matters: it makes bookkeeping mechanical instead of forensic, it simplifies your tax return prep dramatically, and it's required to maintain corporate-veil protection if you've used an LLC. Comingled accounts can let creditors pierce the LLC and reach your personal assets.
Add a dedicated business credit card for property expenses too. Use it for everything — Home Depot, plumber visits, paint, mileage. Pay it off from the rental account each month. Now every transaction is automatically categorized and timestamped.
The 15 Schedule E expense categories
Schedule E (Form 1040) is where rental income and expenses are reported. There are roughly fifteen categories you'll use. Set up your bookkeeping software with these exact buckets so categorization at tax time is one-to-one.
Income side
Gross rental income (rent collected, not rent owed), late fees collected, pet fees, application fees retained, and any other tenant-source income.
Expense side
Advertising, auto and travel, cleaning and maintenance, commissions (if any), insurance, legal and other professional fees, management fees, mortgage interest paid to banks, other interest, repairs, supplies, taxes, utilities, depreciation expense (calculated annually), and other expenses (HOA dues, software, subscriptions).
Software: what to use
Stessa (free) is the most popular landlord-specific tool. Connects to bank accounts, auto-categorizes transactions, generates Schedule E reports, tracks per-property P&L. Best for portfolios of 1-20 doors. The free version covers most owners' needs.
QuickBooks Online ($30-$90/month) is overkill for one property but invaluable at 5+ doors with multiple LLCs. More accountant-friendly when you eventually hire a CPA. See our software tools roundup for more options.
Excel/Google Sheets works fine for 1-2 properties if you're disciplined. Build a simple template with date, property, category, amount, and notes columns. The discipline of weekly entry is more important than the tool.
Don't use Mint, Personal Capital, or general personal-finance apps. They're not designed for rental categorization and will frustrate you.
Receipt management
Keep a digital copy of every receipt over $75 (the IRS threshold below which receipts aren't required, though documentation still helps). Use one of:
Phone scanning apps like Adobe Scan, Microsoft Lens, or Stessa's built-in receipt capture. Snap immediately at the cash register. The system uploads to cloud storage indexed by date and amount.
Email folder. Online purchases and digital receipts go to a dedicated email folder labeled by year. At year-end, export and zip.
Physical box as backup. Some landlords still keep a labeled file box per property per year. Old-fashioned but bulletproof during an audit.
IRS rules require records for 3 years from filing date (7 years if you've claimed losses or claimed depreciation that matters in a future sale). Store digital records on cloud backup, not just one device.
Mileage tracking
Driving to and from your rental property is deductible at the standard mileage rate (around 67 cents per mile in 2026). Active landlords easily log 2,000-5,000 deductible miles per year, which translates to $1,300-$3,300 in deductions. Most people forget to track it and lose every dollar.
Use an automatic tracker — MileIQ, Stessa's built-in tracker, or QuickBooks mileage. They run in the background and let you classify trips as personal or business with a swipe. Manual logbooks work but require discipline most people don't sustain.

The monthly close routine
Block 30-60 minutes the first weekend of each month for a "monthly close." The routine:
1. Reconcile each bank and credit card statement to your software.
2. Categorize any uncategorized transactions.
3. Match scanned receipts to bank-side transactions.
4. Log mileage from the tracking app.
5. Run a quick P&L per property — does this month's net match expectations?
6. File next month's bills (mortgage statements, insurance renewals, tax bills).
Done monthly, this takes an hour. Done annually in March, it takes 20 hours, you'll miss things, and your CPA will charge double.
Tracking depreciation
Depreciation is your largest non-cash deduction. Building basis is depreciated over 27.5 years on residential rentals. The system auto-calculates if you set it up correctly:
Depreciable basis = purchase price + closing costs + capital improvements − land value. Annual depreciation = depreciable basis / 27.5. See our depreciation guide for the full mechanics, including bonus depreciation and cost segregation strategies.
Track every capital improvement separately with date, cost, and asset class. Each one starts its own depreciation schedule. Software tracks this automatically; spreadsheet users need a "Capital Improvements" tab.
Audit-proofing
Schedule E with rental losses gets audited at higher rates than W-2-only returns. The IRS knows that landlords sometimes miscategorize, double-deduct, or claim improvements as repairs. Audit-proof your books by:
Keeping every receipt over $75. Logging mileage contemporaneously. Getting professional invoices (not handwritten) from contractors. Tracking the de minimis safe harbor election in your records. Maintaining a separate file of all 1099-NECs issued to contractors paid more than $600/year.
When to hire a CPA
Most landlords with 1-3 properties can self-file with TurboTax or FreeTaxUSA. Hire a CPA when: you have 4+ properties, you've done a 1031 exchange, you're claiming real estate professional status, you've done a cost segregation study, or your taxable income is over $250,000. A real estate-focused CPA charges $800-$2,500/year and typically saves multiples of that in legitimate deductions you'd miss.
The bottom line
Bookkeeping isn't glamorous, but it's the highest-ROI hour of your week. Separate accounts, simple software, monthly close discipline, religious mileage tracking. Set this up in your first 90 days as a landlord and you'll thank yourself for the next decade.
