Your rental's placed-in-service date is not your closing date.

Every autumn we get the same question in different words. Someone is under contract on a rental closing in November or December and wants to know whether it still does anything for this year's taxes. Buried in it is an assumption worth pulling apart: that closing day is the day depreciation starts. It isn't. The date that governs your first year is the placed-in-service date, and on a property needing any work at all, those two dates can sit months apart.

What does “placed in service” actually mean for a rental?

A rental is placed in service when it is ready and available for its intended use: the unit is in a condition to be rented, and you are holding it out for rent. Ready means habitable and functionally complete — utilities on, systems working, any certificate of occupancy in hand. Available means you are marketing it: listed, advertised, a property manager engaged.

What it does not require is a signed lease. A vacant unit that is rent-ready and genuinely on the market is placed in service even if nobody moves in until February; a tenant signing is evidence of readiness, not the trigger. The flip side holds too: a property you have chosen to hold empty until spring, with no listing and no marketing, is not placed in service just because you own it.

Does closing on the property start the depreciation clock?

No. Closing settles ownership and fixes your basis; it says nothing about readiness. Sometimes the dates collapse into one — buy a turnkey duplex with paying tenants in place and the property was ready and available the day you took title. But close on a tired single-family that needs a furnace, flooring, and a deep clean before anyone would rent it, and the clock waits until that work is done and the listing goes up.

It cuts both ways: a hurried December closing on a property that will not be rent-ready until March buys you nothing this year, while an October closing on a unit you list in November does.

What if the property needs work before you can rent it?

Then the work you do before that date is treated differently from the work you do after. Costs to get a property ready for service are generally capitalized into basis rather than deducted as current repairs. That is mostly not bad news: those dollars are not lost, and a meaningful share of them — flooring, cabinetry, appliances, fixtures, dedicated electrical and plumbing, exterior improvements — lands in the short-life buckets a study is built to find.

What matters practically is that you can prove the date. Keep the timestamped first listing, the advertisement, the management agreement, the certificate of occupancy, the utility transfer, the key-handoff record. It is a small file that answers the only question anyone asks later, and the difference between an audit-ready position and an argument.

Why the placed-in-service date decides your entire first year.

Because two different rules run off it, and they behave nothing alike. The building itself — the 27.5-year residential portion — is prorated by the mid-month convention. Place a property in service in November and you get half of November plus December: about a month and a half of a full year's straight-line depreciation. On its own, a rounding error.

The short-life property is the opposite. The 5-, 7-, and 15-year components a study identifies are eligible for bonus depreciation, and bonus is not prorated by month. For property acquired after January 19, 2025, the One Big Beautiful Bill restored the 100% rate, which we walk through in our note on the restored rule. A December placed-in-service date claims the same full bonus deduction a January one would. Put those together: a late-year rental is nearly worthless without a study, and quite valuable with one.

The math on a $410K rental placed in service in November.

Say you close in October on a $410,000 single-family rental, spend three weeks making it rent-ready, and list it in mid-November. Carve out land first, call it 20%, leaving $328,000 of depreciable basis.

Without a study, that entire $328,000 sits in the 27.5-year bucket. Straight-line, that is about $11,927 a year, and the mid-month convention hands you roughly a month and a half of it: about $1,491 of first-year depreciation.

With a study, a reasonable residential result reclassifies around 22% of basis — about $72,160 — into 5-, 7-, and 15-year property, fully deductible this year under 100% bonus. The remaining $255,840 stays on 27.5 years and contributes about $1,163 for the stub period. First-year depreciation: roughly $73,323.

That is about $71,832 of additional deduction in a year that would otherwise have produced almost nothing. At a 32% marginal federal rate, call it $22,986 in year-one federal tax savings, before any state effect. Whether the resulting loss is usable against your other income turns on passive-activity rules and how you participate; a loss you cannot use now carries forward rather than disappearing.

What about a property still under renovation on December 31?

Then it is next year's property, and the honest advice is not to contort the facts to make it this year's. Listing a half-finished unit you have no intention of renting, purely to manufacture a December date, is a position that does not survive scrutiny. The deduction is not lost by waiting, it moves — and the later year is often better anyway, because the rehab spending lands in basis. We cover the wider timing question in our year-end note.

What to do before year-end.

Three things, in order. Get the unit genuinely rent-ready and listed, because that is the date that counts. Save the evidence while it is easy to save. Then run the numbers before December, so the decision is informed rather than retroactive — the savings estimate takes about two minutes and shows your projected savings and your flat study fee before any payment. There are properties where a study does not pencil, and we will say so. Start with the free instant estimate, or call us for a candid yes or no.
