What happens when the IRS audits your rental property?
It starts with a letter, never a phone call, asking for the records behind specific lines of your return. For a landlord those are usually rents received, repairs versus improvements, the basis behind depreciation and any loss you deducted. Most audits cover returns filed in the last two years, a mail audit usually allows one 30 day extension, and if your books are in software the examiner will often ask for the file itself.
How an audit starts
The IRS audits page is plain about the first contact: if your return is selected, you are notified by mail, and the IRS will not start an audit by telephone. A call or text claiming to be an IRS audit is a scam until a letter says otherwise.
Returns are picked in a few ways. Some are chosen by a statistical formula that compares your return with norms for similar returns. Others are related examinations: your return is pulled because it involves someone whose return is under audit, such as a business partner. For a multi-member LLC, a partner's audit can reach the other partners. The IRS also says a refund is not necessarily a trigger.
The timeline, step by step
- The letter arrives. It names the year, the items under review and a response date. A mail audit asks for documents; an office or field audit sets an interview.
- If you need time, ask before the date. For a mail audit the IRS can ordinarily grant a one-time automatic 30 day extension by fax or mail.
- If you have too many records to mail, you can ask for a face-to-face audit instead.
- If you keep books in accounting software, the examiner may send Form 4564, an information document request, for a backup file early in the exam.
- The audit closes one of three ways: no change, agreed (you sign the report) or disagreed (you can appeal).
- If a Notice of Deficiency arrives by certified mail, the 90 days to petition the Tax Court cannot be extended.
How far back: generally the last three years, more if a substantial error turns up, and usually not more than six. Most audits are of returns filed in the last two years. The IRS may ask you to extend the statute of limitations to finish; you do not have to agree, but then the examiner decides on what you have provided.
What to hand over, line by line
The IRS records request page says the request should not require you to create anything new, since these are the records you used to prepare the return. It asks for copies, never originals, organized by year and type with a summary. For Schedule E that usually means:
| Schedule E item | What the examiner tests | What to have ready |
|---|---|---|
| Rents received (line 3) | That every deposit is counted | Bank statements, the rent roll and a reconciliation of deposits to reported rent |
| Repairs (line 14) | That nothing on the line is an improvement | Each invoice with a description of the work |
| Mortgage interest (line 12) | Interest only, not principal or escrow | Form 1098 and lender statements; the loan agreement and settlement sheet |
| Depreciation (line 18) | The starting basis and the land split | The closing statement, the land and building allocation and the list of improvements |
| Auto and travel (line 6) | Business purpose and miles | A mileage log with dates, places and purpose |
| A rental loss you deducted | That you qualified to deduct it | Records of your participation and hours |
The IRS adds that no record stands on its own: include the circumstances around any document, such as what a bill was for and how it relates to the rental.
If your books are in software
The IRS electronic records FAQ says examiners will request accounting software backup files in most cases where a business already keeps its books that way, especially in broad audits such as verifying gross income. They ask for administrator access, and suggest changing the password to a temporary one for the backup. They then run reports and drill down to test whether the records are reliable.
That is a strong reason to keep books that match the bank month by month. An examiner who finds deposits in the bank that are not in the books starts asking about income, not just expenses.
How a reclassified repair changes the result
Example a made-up owner of a 14 unit building deducted $48,600 of repairs for 2024. The examiner reviews the 31 invoices and moves one, a $12,000 replacement of a full roof section finished in July 2024, to improvements. The repair deduction falls by $12,000. The improvement is depreciated over 27.5 years instead. Under the mid-month convention described in Publication 527, a July start counts 5.5 months of 2024, so the first year allows 12,000 divided by 27.5, times 5.5 over 12, or $200. Taxable rental income rises by $12,000 minus $200, or $11,800.
Clean invoices cut both ways: they let you defend the repairs that are truly repairs, and they make any adjustment small and quick instead of an open-ended dispute.
How DoorKeeping keeps you audit-ready
DoorKeeping keeps each property's books from its bank feed, with deposits matched to tenants, bills read and coded by AI with the invoice attached, and a month-end close that reconciles the account. Expense accounts map to Schedule E lines, so you can ask your AI app for every repair over $1,000 on one building in 2024 with its invoice, or a reconciliation of deposits to rent, and hand it over as copies. DoorKeeping does not represent you before the IRS; a CPA, enrolled agent or attorney can. It costs $2 per unit per month, with no other fees for owners or tenants.
