Photograph the invoice at the moment you pay it. Not later, not at the end of the month, at the moment the money leaves. That single habit recovers more deductions than any filing system, because the receipts you lose are never the ones you filed badly. They are the ones you never captured.
Everything below assumes you have done that part.
The four fields that make a receipt useful
A photo of an invoice in a camera roll is a photo. What makes it usable a year later is four pieces of information attached to it:
- Which unit. Not which property. The unit, if you own anything with more than one.
- What it was for. “Plumbing” is enough. “Repair” is not.
- Repair or improvement. One is deductible this year, the other is capitalized. Deciding at the time is far easier than reconstructing it in March.
- Who was paid, and how much this year. This is the 1099 question, and it is easier to keep running than to total in January.
If your current system cannot answer all four for a random invoice from eight months ago, it is not a system, it is a folder.
The 1099 threshold moved
For years the rule was simple to remember: $600 to a contractor in a calendar year meant a 1099. That changed. The IRS instructions for Forms 1099-MISC and 1099-NEC state that for tax years beginning after 2025, the minimum threshold for reporting certain payments rose to $2,000, with inflation adjustment beginning in calendar year 2027.
Two practical consequences. The number of vendors you have to report drops, and the number of landlords who guess wrong about it goes up, because the old figure is repeated everywhere. Keep a running per-vendor total either way. It costs nothing while you are already recording the payment, and reconstructing a year of payments to one plumber in January is miserable.
Collect a W-9 from any new vendor on the first job, before you owe them anything. A vendor who has been paid is much harder to get paperwork out of than a vendor who is waiting to be paid.
Repair or improvement, decided at the time
This is where real money moves. A repair comes off this year’s income. An improvement is capitalized and recovered over years. Same plumber, same day, two different tax outcomes depending on what the work actually was.
The IRS tangible property regulations give small landlords three simplifying elections, and the first one carries most of the weight: a de minimis safe harbor letting you deduct amounts paid to acquire or produce tangible property, up to $2,500 per invoice or per item, if you do not have an applicable financial statement. That covers a large share of what a small portfolio actually spends money on.
Which is a strong argument for asking vendors to itemize. One invoice reading “kitchen work, $4,100” is a problem. The same job broken into a $2,300 appliance and $1,800 of labor and parts is a different conversation with your accountant. Ask for the detail while they are writing the invoice, not after.
Capital improvements versus repairs works through the test itself and the other two elections.
Allocate to the unit, not the building
Landlords with more than one unit almost always track at the property level, because that is how the bank statement reads. It hides the thing you most need to see.
Per-unit spend tells you which unit is expensive. A duplex where one side has cost $4,800 in repairs over two years and the other side $600 is not a duplex with a maintenance problem, it is a unit with a specific problem, and the invoices will usually tell you which one if they are sitting together.
It also matters at move-out. A repair invoice dated during a tenancy, attached to that unit, is the difference between a deposit deduction you can support and one you are asserting. Keep the invoice, the before photo, and the work order in the same place.
Three habits, in order of payoff
- Capture at payment. Photograph or forward the invoice the moment you pay. If you do nothing else from this post, do this.
- Tag with the unit and the category on the same day. Sixty seconds while you still remember what the job was. In April you will not.
- Reconcile monthly, not annually. Match invoices to the bank feed once a month. A missing receipt found in February is recoverable. Found in March, it is a lost deduction.
A spreadsheet can do all three, and for one or two units it is fine. It stops being fine when the invoice lives in one place, the photo in another, and the work order in a text thread. Spreadsheet versus software for maintenance tracking is an honest look at where that line falls. LeaseRooster’s accounting keeps the expense on the unit it belongs to and the invoice attached to the work order it came from.
What this is worth
Run the math on your own numbers rather than trusting a percentage from a blog post. Take last year’s repair spend, guess honestly how much of it you have no receipt for, and multiply by your marginal rate. Whatever that number is, it is the price of a filing habit, not of anything you did wrong on a property.
If you are trying to work out what a unit costs to run in the first place, the cost calculator is a reasonable starting point.
