Wrong Rental Depreciation Start Date?

Usually, first establish the month the rental was ready and available for rent. If a filed return used a different placed-in-service date, recalculate that year's depreciation and evaluate a corrected return and later-year schedules. The IRS says changing an asset's placed-in-service date is not an accounting-method change made on Form 3115. A tenant's move-in date and your closing date are evidence, not automatic depreciation start dates.

If your filed Schedule E or fixed-asset schedule begins depreciation in the wrong month or year, bring the return, closing statement, renovation timeline, first rental listing, and asset ledger to a review. AE can trace the date through the deduction and future basis before you amend.

Was the rental actually ready for a tenant?

IRS Publication 527 uses a ready-and-available test. Its example buys a rental in April, completes extensive work and advertises it in July, and rents it in September: depreciation starts in July. Another example installs an appliance after year-end; delivery alone does not make the appliance ready. A listing supports availability, but a listing for a home still uninhabitable because of major work does not by itself establish that it was ready.

Separate an acquired property undergoing a first-time renovation from a rental already in service that is temporarily vacant for repairs. Publication 527 says the latter generally continues depreciating while temporarily idle. Also track later capital improvements and separately depreciable appliances on their own asset lines; their dates need not match the building's date. A former personal residence requires a separate conversion analysis, including the depreciation-basis limit described in our home-to-rental conversion guide.

If the return is filed, what needs correcting?

Document the actual date. Make a dated timeline of completion, inspections, utilities, insurance, photographs, listings, inquiries, and first occupancy. Explain any gap between advertised availability and move-in.
Rebuild each affected asset line. Reconcile land and building basis, separate improvements, recovery period, convention, and depreciation allowed or allowable. The date error can affect the first and final years, even when intervening full-year deductions are unchanged.
Choose the correction procedure by the error, not the form name. Publication 946 lists a change in placed-in-service date among depreciation changes that are not accounting-method changes and may only be made on an amended return; the Form 3115 instructions explicitly say not to file that form to change the date. Review which years remain open, any prior amendments, and the taxpayer's entity filing path. A separate impermissible depreciation method may require its own analysis; do not bundle it into the date fix without review.
Reconcile downstream returns. Correct accumulated depreciation, passive-loss carryforwards if affected, state filings, and the basis schedule used on a later sale. If claiming a refund, check the applicable claim deadline; the IRS states a general three-years-from-filing or two-years-from-payment rule, whichever is later, with exceptions.

Example: listed in July, rented in September

Assume a calendar-year owner bought a duplex, finished the work and offered both units for rent in July, but the first tenant moved in during September. The building's supported depreciable basis, excluding land, is $275,000. Under the ordinary 27.5-year GDS straight-line and mid-month assumptions, a July first year is about $4,583 of depreciation; a September start is about $2,917. Recording September because that is when rent first arrived understates the first-year building deduction by about $1,667. The actual return may differ because of improvement dates, elections, personal use, or other assets. Correcting the first-year amount also requires a reconciled cumulative schedule; merely changing the date in bookkeeping software does not fix a filed return.

Documents and failure points for a review

Purchase and land-allocation records; invoices and final contractor sign-offs; permits, inspections, utilities, insurance, and photographs around the readiness date.
Dated advertisements and listing changes, leasing-agent instructions, inquiries, applications, signed lease, and move-in record.
Filed federal and state returns, Form 4562 or depreciation worksheets, prior amendments, and records for later improvements or appliances.

Common failures are using closing day while the property is not usable, waiting for the first rent check after the property is ready, treating a temporary vacancy in an established rental as a new start date, or using Form 3115 for a date-only error. The amount of any refund and whether a prior year can be changed depend on the filed return and limitation periods; the IRS amended-return guidance is the starting point, not a guarantee of a refund. For broader method-versus-error issues, see amended return versus Form 3115 and wrong rental depreciation basis.

The tax treatment

Depreciation begins when the property is ready and available for its intended rental use, not necessarily when a tenant first moves in or when the purchase closes. This is a federal income tax starting point; the contract, ownership, accounting method, and actual use can change the result. State and local treatment should be checked separately.

The decision to make before filing

Pin down the date repairs ended and active rental marketing began; separate later improvements into their own placed-in-service dates. The useful planning step is to resolve the classification while the underlying documents are still available, then reconcile it to the books and the prior-year return. If the transaction spans more than one year, track the opening balance and what happened to it afterward.

Illustrative example

A buyer closes on a duplex in March, replaces unsafe wiring through May, and first advertises it for rent in June. The owner should not begin building depreciation merely because title transferred in March. Dated contractor completion and listings establish when it became ready and available.

Records that support the position

Keep dated listings, inspection records, contractor completion invoices, and lease applications. Tie amounts on the return to bank activity and the agreement. When several assets, people, or uses are involved, write down the allocation method and apply it consistently. A short dated workpaper is easier to defend than a reconstructed explanation years later.

A common reporting error

Starting depreciation on closing day while major renovations prevent occupancy can accelerate it improperly. Review both sides of the entry: a payment can affect income, basis, liability, or an expense at different times. A correct cash total alone does not establish the correct tax character.

Where to verify the rule

Start with IRS Publication 527: Residential Rental Property. Its examples and cross-references explain the underlying federal rule; check the current version and any later IRS guidance for the year at issue. Publication 946 and the Form 3115 instructions explain why changing the date is not an accounting-method change.
