Rental property bookkeeping basics for small landlords

Most small landlords do their bookkeeping once a year, in a panic, out of a shoebox. It costs them money twice: in deductions they cannot prove, and in the hours they spend reconstructing a year they could have recorded in twelve short sittings. Here is the smallest system that actually works.

Separate the money first

Open a checking account used only for the rentals, and run every rent payment, mortgage, repair and insurance premium through it. If you have a card, get one dedicated to the properties too. This single step removes the hardest part of landlord bookkeeping — deciding, in March, whether a $260 hardware store charge was the rental or your own kitchen.

Keep security deposits out of that operating account where your state requires it, and remember a deposit is not income. It is money you are holding.

Track by property, not in a lump

A total across four units tells you almost nothing. Per-property rows tell you which building is paying for the others, which is the number that should drive your renewal, refinance and sell decisions. Every expense gets a property, a date, an amount and a category — and if it covers several properties, split it proportionally as you enter it, not later.

The free landlord bookkeeping template is set up this way already: monthly entry, per-property totals, and an annual summary that rolls up automatically.

Use the categories the tax form uses

Schedule E has its own list: advertising, auto and travel, cleaning and maintenance, commissions, insurance, legal and professional fees, management fees, mortgage interest, other interest, repairs, supplies, taxes, utilities, depreciation. Categorize into those buckets from the start and your tax preparation becomes transcription rather than archaeology. The Schedule E expense tracker mirrors the form line by line.

Know the repair versus improvement line

A repair keeps the property in the condition it was in and is deductible this year. An improvement adds value or extends the property's life and has to be depreciated over years. Patching a roof is a repair; replacing the roof is an improvement. Fixing a broken dishwasher is a repair; putting in a new kitchen is an improvement. Landlords lose real money by expensing improvements and getting caught, or by depreciating repairs and waiting decades for a deduction they could have taken now. When it is genuinely borderline, ask your preparer once and write the answer down.

Keep receipts in a way you will still have in three years

The IRS generally looks back three years, and longer in some situations. Photograph every receipt the day you get it and file it in one folder per property per year, named by date and vendor. A deduction you cannot document is a deduction you do not have.

The monthly hour

Pick a date — the 5th works, after rent has landed. Record what rent was due and what actually arrived, enter the month's expenses from the bank statement, file the receipts, and note anything outstanding. That is the whole job. Twelve of those and your tax year is finished before you start it. If you would rather not maintain the file at all, PLINTH does this continuously for $7 a month, with the ledger attached to each property.
