Real Estate Tax Calc
The core documents you need
The following records are the foundation of a defensible depreciation schedule:
Original closing statement (HUD-1 or Closing Disclosure): establishes your total cost basis, which items are depreciable (building vs. land), and separates the purchase price from financing costs.
Land value documentation: the county assessor's land-to-improvement ratio, an appraisal, or a real estate tax bill that splits land from building. This determines how much of your purchase price is depreciable.
Annual Form 4562: your depreciation schedule filed with each tax return. Save every year's copy. This is the running record of what you have claimed, asset by asset.
Cost segregation study (if applicable): the engineering study and the resulting asset list, with each component's cost, class life, and placed-in-service date.
Capital improvement receipts: invoices and contracts for every improvement you capitalize, with the date placed in service. Each improvement starts its own depreciation timeline.
Why these records matter more than you might think
The IRS taxes depreciation recapture on amounts 'allowed or allowable' — meaning you owe recapture on the depreciation you could have claimed even if you skipped the deduction. If you have no records, an examiner may reconstruct your depreciation from the worst-case assumptions for you.
When you sell: your adjusted basis = purchase price + improvements − accumulated depreciation. Without an improvement log, you lose the basis step-ups that reduce your gain. Without a depreciation schedule, the split between capital gain and recapture is guesswork — and the wrong split costs you money.
How long to keep them
Keep all depreciation-related records for the entire period you own the property plus at least three to six years after the year you file the final return for the property. Because the cost basis connects purchase to sale, a complete file may need to span decades. The IRS has an unlimited statute of limitations when there is substantial understatement of income (more than 25%) or fraud, so clean records matter for as long as the gain or recapture remains open.
Digital scans stored in cloud backup are entirely acceptable. The most practical system: create a dedicated folder per property and add every receipt, Form 4562, and closing statement to it when generated rather than hunting for them years later.
The land-versus-building allocation: get it right on day one
Only the building depreciates — land never does. The single most consequential record for a rental is proof of how you split the purchase price between land and improvements, because that ratio drives every year's deduction and your basis at sale.
Acceptable support, roughly in order of strength: a formal appraisal that separates land and improvements; the county assessor's allocation from the property tax bill (e.g., if the assessment is $250,000 with $50,000 land and $200,000 improvements, 80% is depreciable); a replacement-cost analysis; or a cost segregation study. Whatever method you choose, document it and stay consistent. An examiner who finds no basis for your allocation may substitute a higher land percentage, permanently shrinking your deductions.
Worked example: a $300,000 purchase with an 80% improvement ratio yields a $240,000 depreciable basis. Over 27.5 years that is about $8,727 a year. Push the land allocation to 30% by accident and you lose roughly $1,100 of deduction every single year — and you still owe recapture on the depreciation you were allowed to take.
Records that separate a repair from an improvement
The receipts you keep have to do more than prove you spent money — they have to establish character. A repair (fixing a leak, repainting, replacing a broken window) is generally deducted in full in the year paid. An improvement — a betterment, restoration, or adaptation under the tangible property regulations — is capitalized and depreciated.
For each significant expenditure, save the invoice, a short note on what was done and why, and before/after photos where helpful. That contemporaneous detail is what lets you defend a current deduction, or support a de minimis safe harbor election (generally up to $2,500 per item or invoice) or the safe harbor for small taxpayers, rather than capitalizing everything by default.
Keep your annual elections too. The de minimis safe harbor, the routine-maintenance safe harbor, and the partial-disposition election are all made by statement or by how you report — and the paperwork proving you made them belongs in the property file.
Records for partial dispositions and replaced components
When you replace a major component — a roof, an HVAC system, windows — you can elect a partial disposition to write off the remaining basis of the old component and stop depreciating something that no longer exists. To do that you need records establishing the original component's cost (or a reasonable allocation of it) and the depreciation already taken on it.
Skipping the partial disposition means you keep depreciating the old roof and the new one simultaneously, and you carry phantom basis you will have to recapture at sale. The election is only as good as the records behind it, so note the original cost allocation whenever you capitalize a replacement.
What examiners actually ask for
In a rental depreciation exam, the requests are predictable: the closing statement establishing basis, the land/building allocation and its support, every year's Form 4562 or depreciation worksheet, invoices for capitalized improvements with in-service dates, and — if you used one — the cost segregation report. If a prior-year deduction looks aggressive, expect a request for the underlying receipt and a description of the work.
The pattern that draws scrutiny is a large first-year deduction (bonus depreciation or a cost seg catch-up) with thin documentation. Clean, organized records turn a potential adjustment into a five-minute confirmation. Missing records shift the benefit of the doubt to the examiner.
Reconstructing lost records
If your file has gaps, you can often rebuild it. Order prior-year returns and account transcripts with Form 4506 (full copy) or Form 4506-T (transcript) to recover past Form 4562 schedules. Pull historical assessor records for the land/building split, and ask your title company or lender for a copy of the original closing statement.
Document your reconstruction method in a dated memo. A reasonable, well-explained reconstruction is far stronger than silence — but it is always second-best to keeping the originals as you go.
State recordkeeping and depreciation differences
A few states do not fully conform to federal bonus depreciation or Section 179, so your state depreciable basis and accumulated depreciation can differ from federal. If you invest in one of those states, keep a separate state depreciation schedule; otherwise your state gain and recapture at sale will be miscomputed.
Depreciation records also matter for nonresident state filings. If your rental sits in a state where you don't live, that state generally taxes the gain and recapture on sale, and it will expect the same basis documentation the IRS does. Retain records for as long as either the federal or the state statute of limitations on the sale year remains open — whichever is longer.
A practical filing system that survives an audit years later
Organize by property, then by category. A simple, durable structure: one top-level folder per address, with sub-folders for (1) acquisition (closing statement, purchase appraisal, land/building allocation support), (2) an annual depreciation folder holding each year's Form 4562 or worksheet, (3) capital improvements (one PDF per project: invoice, contract, in-service date, photos), (4) any cost segregation study, and (5) disposition (eventual sale documents).
Keep a one-page basis summary at the front of each property folder — a running ledger of original basis, each improvement with its date and amount, and cumulative depreciation by year. When you sell, that single page drives the entire gain, recapture, and Form 4797 calculation, and it lets a preparer or examiner verify your numbers in minutes.
Back up everything to cloud storage and export a copy at least annually. Paper fades and hard drives fail; a rental basis file may need to survive twenty or thirty years of ownership plus the open statute of limitations after sale. The cost of storage is trivial next to the tax cost of a lost allocation or an unproven improvement.
Frequently asked questions
How long should I keep rental property depreciation records?
At minimum, the entire ownership period plus 3–6 years after the final return for that property. Because basis and recapture connect purchase to sale, a complete file may span decades.
What if I lost my original depreciation schedules?
You can reconstruct the schedule from prior tax returns (request copies with IRS Form 4506-T), the original closing statement, and assessment records for the land-to-building split. Document your reconstruction method in case of audit.
Do I need to keep improvement receipts if I already capitalized them?
Yes. The amount on your depreciation schedule proves what you deducted; the receipt and date prove when it was placed in service and what you paid. Both are needed to defend the deduction.
What is the single most important depreciation record to keep?
The support for your land-versus-building allocation. Only the building depreciates, so the ratio you used — from an appraisal, the assessor's split, or a cost segregation study — drives every year's deduction and your basis at sale. Without it, an examiner can assign a higher, non-depreciable land percentage.
How do I recover depreciation schedules I lost?
File Form 4506-T for tax transcripts or Form 4506 for full copies of prior returns to recover past Form 4562 schedules, then supplement with assessor records and the original closing statement. Write a dated memo explaining how you reconstructed the numbers.
Should I keep records proving an expense was a repair rather than an improvement?
Yes. The invoice plus a short description and photos establish whether an item was a currently deductible repair or a capitalized improvement, and they support any de minimis or small-taxpayer safe harbor elections you claimed.
Do I need separate records for state depreciation?
Sometimes. States that do not conform to federal bonus depreciation or Section 179 produce a different state basis and accumulated depreciation. If your property is in such a state, keep a separate state depreciation schedule so your state gain and recapture at sale are correct.
