Your Maintenance Log Is Your Tax Record

Every landlord knows repairs are deductible. Far fewer know that "repair" is a category the IRS defines narrowly, and that the same $1,800 plumbing invoice can be a deduction this year or an asset you depreciate for the next 27.5 years, depending on what the plumber actually did.

The deciding evidence is almost never the invoice. It's the record of the work, and that record is your maintenance log.

Repair or capital improvement, in plain English

This is the distinction that matters:

• A repair keeps the property in its ordinary operating condition. Patching a leaking supply line, replacing a cracked window pane, servicing an AC unit. Generally deductible in the year you pay for it.
• A capital improvement makes the property better, restores it after major deterioration, or adapts it to a new use. A new roof, a full HVAC replacement, a kitchen remodel. Generally capitalized and depreciated over years instead of deducted at once.

The line between them isn't decided by the dollar amount alone, and it isn't always obvious. Replacing one section of a pipe is a repair. Replacing the whole supply line to modernize the unit starts to look like an improvement. Same plumber, same trip, very different tax treatment.

Why the invoice alone doesn't answer it

Picture your records at year end: "Acme Plumbing, $1,840." That tells your CPA who got paid and how much. It doesn't say whether the plumber fixed a leak or replaced the whole line, and it doesn't say which unit it was for. If nobody wrote down what happened when it happened, you're reconstructing it from memory in March, and your CPA is making judgment calls on incomplete information.

A maintenance log fixes this at the source. When each request has a description of the problem, who did the work, what they did, and what it cost, the repair-or-improvement question mostly answers itself. The record should be property-level, too. Books that mix costs across properties are much harder to defend and much harder to depreciate correctly.

Three IRS safe harbors worth asking about

The IRS has a few safe harbors that let small landlords deduct certain costs right away, and every one of them rewards good documentation. These are the ones to raise with your CPA:

• De minimis safe harbor. Items or invoices at or under $2,500 can be deducted immediately, provided you have a consistent written accounting policy at the start of the year and make the annual election with your return.
• Routine maintenance safe harbor. Work you reasonably expect to do more than once in a 10-year period on a building, like repainting or recurring servicing, can generally be expensed.
• Small taxpayer safe harbor. For buildings with an unadjusted basis under $1 million, you may be able to deduct repairs and improvements up to the lesser of $10,000 or 2% of that basis per year.

Eligibility depends on the details of your situation, so use this list as a set of questions for your CPA. What doesn't change is that every one of these requires documentation to back it up.

What a tax-ready maintenance log holds

For each request, capture:

1. The date it was reported and the property or unit it applies to.
2. A plain description of the problem, in the tenant's words if you have them.
3. Who did the work, and the date it was completed.
4. What was actually done. This is the line your CPA cares about most.
5. The invoice number and amount, plus a photo of the invoice or receipt.
6. Before and after photos when the job is more than a quick fix.
7. A one-line note on whether you consider it a repair or an improvement, written while the details are fresh.

How Doot's expenses page makes this easy

The log only helps if you actually fill it in, and the moment to do that is the day you pay the bill. Doot's expenses tools are built around that habit:

• Every expense belongs to a property. You pick the property when you log it, so your books stay separated property by property from the start, with a running total for each.
• The note field is your job description. Log the cost under "Maintenance & Repairs" and write what the work was, in one line: "Replaced 6 ft of corroded supply line under kitchen sink, leak repair." Add "repair" or "improvement" if you've made the call. That sentence is what your CPA will look for.
• The receipt is attached to the entry. Upload a photo of the invoice on the expense itself, so the paper trail and the amount live in one place instead of a shoebox and a spreadsheet.
• You can log it by chat. Tell Doot's assistant "log a $240 plumbing repair at the Elm St property for today" and it records the expense. Add the receipt afterward from the dashboard.
• Year-end is an export, not a project. Download a property's expenses as a CSV and hand it to your CPA, or edit it and import it back in.

Doot also keeps a full timeline for each maintenance request, the tenant's texts, the contractor's call transcripts, and the scheduled time, so the story of what happened is on file alongside the expense you log for it. If you want the operational side, where the tenant texts the issue and the scheduling handles itself, that's the maintenance request flow. And if you're wondering how fast a repair should happen in the first place, start with how long a landlord has to fix the AC.
