Real Estate Tax Calc
Ready and available, not necessarily occupied
A property is placed in service when it is ready and available for use in your rental activity. A vacant property that has been renovated and is actively marketed for rent is placed in service — you don't need a paying tenant in place to start depreciating.
Why the date matters
The placed-in-service date determines which tax year depreciation begins and sets the mid-month convention start for your MACRS schedule. It also determines which rules govern the recovery period. Getting this date right ensures you don't miss deductions in the year you complete renovations.
Conversions require extra care
When you convert a personal-use property to a rental, the placed-in-service date is the date of conversion — not the original purchase date. Your depreciable basis is the lower of your adjusted basis or the fair market value at conversion — a rule that surprises landlords who converted a primary home that had declined in value.
What 'ready and available' means in practice
The standard is functional readiness, not occupancy. A property is placed in service when it is in a condition to perform the function for which you acquired it — a rentable dwelling — and you have made it available by holding it out for rent. Concretely, that usually means the certificate of occupancy is in hand where required, essential systems work, and you have started marketing: a listing is live, a sign is up, or you have engaged a property manager to fill it.
Two nuances matter. First, minor cosmetic work still in progress does not necessarily delay the date if the unit is genuinely habitable and being advertised. Second, you cannot claim a property is 'available' if it is not actually rentable — an unfinished renovation with no kitchen or no working heat is not placed in service, no matter how eager you are to start depreciating. Keep evidence of the readiness date and the marketing start date; they anchor everything else.
Why the date changes your first-year deduction
Residential rental real estate uses the mid-month convention, so MACRS treats the property as placed in service in the middle of the month it became available — and each month carries a different first-year percentage. A property ready in January gets a first-year factor of about 3.485%, while one ready in December gets only about 0.152%. On a $250,000 building basis, that is roughly $8,700 of first-year depreciation for a January date versus about $380 for a December date. The month you cross the placed-in-service line is therefore one of the highest-leverage timing decisions in the first tax year.
Costs before the property is in service
Money you spend to get the property ready is treated differently from money spent once it is operating. Pre-service acquisition and improvement costs — renovations, the initial rehab, and acquisition closing costs — are capitalized into basis and depreciated once the property is placed in service; they are not immediate deductions. By contrast, ordinary operating expenses (repairs, utilities, management, insurance) become deductible once the property is in service and held for rent.
This is why the placed-in-service date is a dividing line, not just a start date. A repair done during the rehab, before the property is available, is generally part of the capitalized rehab; the same repair done after a tenant moves in is a current deduction. Carrying costs like property taxes and mortgage interest during the pre-rental rehab have their own rules and may need to be capitalized in some cases — track them separately.
Each asset has its own placed-in-service date
A rental is not a single asset. The building has one placed-in-service date, but a new roof, a replacement HVAC system, new appliances, or a repaved driveway installed later each has its own date and starts its own depreciation schedule — 27.5 years for structural improvements, 5 years for appliances, 15 years for land improvements. If you buy appliances in March but the unit is not ready to rent until June, the appliances are placed in service when the rental activity begins in June, because they are not available for their intended use until then. Recording each asset's date correctly is what keeps your depreciation schedule accurate over the years.
Common placed-in-service mistakes
The frequent errors: waiting for a tenant before starting depreciation (wrong — availability, not occupancy, is the test, so you may lose deductions for a vacant-but-listed period); using the purchase date for a converted home instead of the conversion date; forgetting the lower-of-basis-or-FMV rule on a converted personal residence; and lumping a mid-year improvement into the building's original schedule instead of giving it its own date and recovery period. Each mistake either overstates or understates your deductions and can create problems at sale, when recapture is calculated from the schedule you actually followed.
Evidence that pins down the date
Because the placed-in-service date drives your first-year deduction and the recovery start, back it up with contemporaneous records. Useful evidence includes the certificate of occupancy or final inspection sign-off, dated listing screenshots or the property manager's engagement letter showing when marketing began, dated photos of the finished unit, receipts showing the rehab was complete, and the first lease or inquiry log. If the IRS ever questions the year you started depreciating, this file is what supports it. The goal is to show the property was both ready (habitable and functional) and available (held out for rent) as of the date you claim.
The converted-home rule in numbers
Converting a former residence deserves a worked example because the basis rule is counterintuitive. Say you bought a home for $400,000, and at the time you convert it to a rental it is worth $350,000, with an $80,000 land value. Your depreciable basis is the lower of adjusted cost basis or fair market value at conversion — here, FMV of $350,000 governs. Subtract land ($80,000, using the FMV-era ratio) to get a $270,000 building basis, and depreciation starts on the conversion date, not the original 2015 purchase date. A special trap follows this rule at sale: if you later sell at a loss, the loss is measured from the lower FMV basis, so a decline that happened while it was your home is not deductible.
Second homes and mixed personal use
A property you also use personally has its own placed-in-service nuance. A true vacation home rented part of the year is placed in service for the rental portion when it is first held out for rent, and depreciation is prorated for personal-use days under the vacation-home rules. If personal use exceeds the greater of 14 days or 10% of rental days, deductions — including depreciation — are limited to rental income and cannot create a loss. Track rental days versus personal days carefully; the placed-in-service date starts the clock, but the personal-use rules cap what you can actually deduct each year.
Timing the date to your advantage
Because the mid-month convention makes an earlier month worth more in year one, there is a legitimate planning angle: if you are finishing a rehab in late December, pushing genuine readiness and active marketing into the property so it is available before year-end can capture a first-year deduction, while a January date shifts the whole benefit to the next tax year. Do not fake it — the property must truly be ready and held out for rent — but the sequencing of when you complete work and list the unit is within your control and has real tax consequences. Coordinate the date with your broader income picture, since a deduction is most valuable in a high-income year.
How the date flows into your depreciation schedule
Once set, the placed-in-service date becomes a permanent field on your depreciation schedule for that asset, alongside its basis, method, and recovery period. Every future year's deduction, the mid-month first-year factor, and the eventual recapture calculation all trace back to it. This is why accuracy at the start saves headaches later: if the date is wrong, every downstream number is wrong too. Record it on Form 4562 in the year of first use, keep your supporting evidence, and carry the same date forward consistently for the life of the asset.
Frequently asked questions
When does depreciation start on a rental?
When the property is ready and available to rent — even if it's currently vacant. Availability, not a paying tenant, is the test.
What is the placed-in-service date for a converted primary home?
The date you convert it to rental use, and the depreciable basis is the lower of adjusted cost basis or FMV at the time of conversion.
Does the month I place a property in service matter?
Yes, a lot. The mid-month convention assigns a different first-year percentage to each month, so a January placed-in-service date yields far more first-year depreciation than a December one on the same basis.
Are renovation costs deductible before the property is in service?
No. Pre-service rehab and improvement costs are capitalized into basis and depreciated once the property is placed in service. Ordinary operating expenses become deductible only after the property is available for rent.
Do appliances and improvements have their own placed-in-service dates?
Yes. Each asset starts its own schedule on the date it is ready for its intended use — the building, a new roof, HVAC, and appliances can all have different dates and recovery periods.
Can I depreciate a property that sat vacant all year?
Yes, if it was genuinely ready and available for rent and actively marketed. A property held out for rent but not yet leased is still placed in service and depreciable.
What proof supports my placed-in-service date?
Keep contemporaneous records: the certificate of occupancy or final inspection, dated listing screenshots or a property manager's engagement letter, photos of the finished unit, and the first lease or inquiry log. Together these show the property was both ready and available as of the date you claim.
