Most landlords do not lose money on taxes because they missed some clever loophole. They lose it because in April they cannot remember what the $340 charge in June was for, so they do not claim it. Rental bookkeeping is not hard — it is just unforgiving of being left until the end of the year.
This guide covers what to record, what you can actually deduct, the one classification mistake that costs the most, and how to set things up so tax time is boring.
This is general information to help you plan and organize, not tax advice. Rules vary by country and situation — confirm the specifics with your accountant.
What the tax form actually wants
In the US, residential rental income and expenses land on Schedule E (Supplemental Income and Loss), filed with your 1040. It is organized per property, and it wants two things from you:
- Total rents received for the year, per property.
- Expenses by category — advertising, auto and travel, cleaning and maintenance, commissions, insurance, legal and professional fees, management fees, mortgage interest, repairs, supplies, taxes, utilities, depreciation, and other.
That category list is the whole trick. If you tag every expense with one of those buckets when it happens, filing is transcription. If you do not, you are reconstructing a year from a card statement.
What counts as rental income
More than the monthly rent:
- Rent received during the year — including rent paid late for a previous year.
- Advance rent — if a tenant pays January in December, it is income in December.
- Security deposits you keep. A deposit you intend to return is not income when you receive it. The portion you keep for damage or unpaid rent becomes income in the year you keep it.
- Tenant-paid expenses. If a tenant pays a repair bill and deducts it from rent, that amount is still rent income to you (and the repair is still your deduction).
- Fees — late fees, pet fees, parking, laundry, cleaning fees on a short-term rental.
Short-term rental hosts: the payout that hits your bank is net of the platform's fee. Your income is the gross booking amount, and the platform fee is a deductible expense. Recording only the payout understates both sides.
What you can deduct
The common ones, in Schedule E's own language:
- Mortgage interest (interest only — the principal portion of your payment is not deductible).
- Property taxes and insurance.
- Repairs and maintenance — see the next section carefully.
- Property management fees and platform / booking fees.
- Utilities you pay.
- Advertising and listing costs, tenant screening, credit checks.
- HOA or condo fees.
- Legal and professional fees — attorney, accountant, bookkeeping software.
- Supplies — anything you buy for the unit, from light bulbs to a replacement toilet seat.
- Cleaning, lawn care, snow removal, pest control.
- Auto and travel — driving to the property for inspections, repairs, showings and supply runs.
- Depreciation — usually the largest single deduction, and the one people skip.
Repairs vs. improvements — the expensive mistake
This is the classification that trips up almost every new landlord.
- A repair keeps the property in its existing working condition. It is deducted in full, this year. Fixing a leak, patching drywall, repainting a room, replacing a broken window pane, servicing the furnace.
- An improvement betters the property, restores it, or adapts it to a new use. It is capitalized and depreciated over years, not deducted at once. A new roof, a kitchen remodel, replacing all the windows, adding a deck, a new HVAC system.
The rule of thumb: fixing is a repair, upgrading or replacing an entire system is an improvement. Repainting after a tenant leaves is a repair. Gutting the bathroom is an improvement.
Why it matters in both directions: claim an improvement as a repair and you have overstated this year's deduction. Treat a genuine repair as an improvement and you have handed yourself a deduction spread thin over 27.5 years instead of taking it now. Tag it correctly when you log it, while you still remember what the work was.
The two deductions people forget
Depreciation. The IRS lets you deduct the wearing-out of the building over 27.5 years for residential property (39 for commercial). Land does not depreciate, so you split the purchase price between land and building and depreciate only the building's share. On a $300,000 property with $60,000 attributed to land, that is $240,000 / 27.5 ≈ $8,727 a year of deduction that costs you nothing out of pocket.
Two things worth knowing: depreciation is not optional in the sense you might hope — when you sell, the IRS assumes you took it (depreciation recapture) whether you claimed it or not. So not claiming it is pure loss. And the split between land and building should be defensible — your property tax assessment usually breaks it out.
Mileage. Every drive to the property for a rental purpose is deductible: inspections, repairs, showings, meeting a contractor, the hardware-store run. You log the date, purpose and miles, then multiply the yearly total by the IRS standard mileage rate. Landlords with a property 20 minutes away routinely leave several hundred dollars on the table here because nobody writes the trips down.
Records to keep, and for how long
Keep the paper trail that supports every number:
- Receipts and invoices for every expense, tagged to a property and a category.
- Lease agreements and any addenda.
- Bank and mortgage statements (the annual 1098 gives you the interest figure).
- Closing documents from the purchase — you need them for the depreciation basis, possibly decades later.
- A mileage log with date, purpose and miles.
- Records of improvements, permanently — they raise your cost basis and reduce your taxable gain when you sell.
General guidance is to keep supporting records at least three years after filing (longer in some situations), and to keep purchase and improvement records for as long as you own the property plus three years. Photos of paper receipts are fine — ink fades, and a faded receipt is an unsupported deduction.
How to set this up so April is boring
The system matters more than the tool. Whatever you use, the goal is: every dollar in or out gets recorded the week it happens, tagged to a property and a category.
- Separate the money first. A dedicated bank account and card for the rental is the single highest-leverage move. Commingling with personal spending is what turns bookkeeping into forensics.
- Log income and expenses per property. In the Rental Income Tracker each property keeps its own ledger, so you never have to untangle which roof repair belonged to which unit.
- Import instead of typing. You can upload a booking statement or an expense screenshot and have the rows read off it, or connect your booking calendar over iCal so stays land automatically. Recurring rent can post itself each month.
- Attach the paperwork to the property. Lease, insurance policy, purchase documents and receipts live with the property rather than in a drawer.
- Log mileage the day you drive. It takes ten seconds and is impossible to reconstruct in April.
- Set the depreciation inputs once. Purchase price, land value and placed-in-service date — after that the yearly figure computes itself.
- Review monthly, not annually. Ten minutes a month, comparing the ledger against the bank feed, catches everything while you still remember it.
At year end the Taxes tab combines your logged expenses with depreciation and mileage into a net-taxable figure, and exports CSVs that map to the Schedule E buckets — so your accountant gets a clean file instead of a shoebox.
Frequently asked questions
Do I have to report rental income if I only rent out a room? Generally yes — renting part of your home is still rental income, and you deduct the share of expenses that applies to the rented portion (usually by square footage or room count). There is a narrow exception in the US for renting your home fewer than 15 days a year, where the income is not reported and the expenses are not deducted.
Is my mortgage payment deductible? Only the interest portion, plus escrowed property tax and insurance if you pay them that way. The principal is not deductible — it is you buying equity, not spending money.
What if I made a loss on the rental? Rental losses are generally passive, and how much you can deduct against other income depends on your income level and how actively you participate. Losses you cannot use are usually carried forward. Track the loss accurately either way — it does not disappear.
Do I need receipts, or is a bank statement enough? A statement proves a payment happened; a receipt proves what it was for. For anything material, keep both, and photograph paper receipts before they fade.
When should I hire an accountant? Once you own more than one property, have a short-term rental, or hit your first improvement-vs-repair judgment call worth thousands. Good books make an accountant cheap; bad books make them expensive.
Does short-term rental income work differently? Often, yes. Average stay length and the services you provide can change how the activity is classified, which affects how losses are treated. The bookkeeping is the same, but the treatment can differ — worth one conversation with an accountant before your first full year.
