- The line. A repair keeps the property in ordinary operating condition and is deducted in the year paid. An improvement betters, restores or adapts it, and is capitalized and depreciated.
- Why it matters. On a $22,000 roof the difference is $6,784 of tax in the year of the work.
- Three elections settle most invoices. The de minimis safe harbor, routine maintenance, and the small taxpayer election.
- They are elections. Most are made on a timely filed original return. Deciding in March, after the year has closed, is deciding late.
Repairs and improvements on a rental are taxed in completely different ways, and the invoice rarely tells you which one you are holding. A repair is deducted in full in the year you pay it. An improvement is added to the basis of the building and written off over 27.5 years under the recovery periods in Publication 946, which means you get about three and a half percent of it back this year and wait a quarter of a century for the rest.
The rule that separates them is in the tangible property regulations, and it is a test rather than a price. Work is an improvement if it betters the property, restores it, or adapts it to a new use. Everything else is a repair.
The test: betterment, restoration or adaptation
An expenditure has to be capitalized if it does any one of these three things to the building, under Treas. Reg. section 1.263(a)-3(d). The IRS summarizes the same framework in its tangible property regulations guidance.
| Test | What it catches | A rental example |
|---|---|---|
| Betterment | Fixes a defect that existed when you bought it, enlarges the property, or materially increases its capacity, strength or quality | Replacing all the windows with a better grade than the ones that were there |
| Restoration | Rebuilds the property to like-new condition, or replaces a major component or a substantial structural part | A full roof replacement, or a whole new HVAC system |
| Adaptation | Puts the property to a use that is new or materially different from the use it was in when you acquired it | Converting a garage into a studio unit |
The one-line version. If the work makes the building better, newer or different, it is an improvement. If it keeps the building the way it already was, it is a repair.
What this looks like on an actual return
If you read nothing else, read this. One invoice, two columns, and the difference is real money in the year of the work.
A landlord filing jointly at a 32 percent marginal rate spends $22,000 on a roof. Nothing about the invoice changes. Only the column it lands in changes.
| On the return | If it is a repair | If it is an improvement |
|---|---|---|
| Cost of the work | $22,000 | $22,000 |
| Deducted this year | $22,000 | $800 |
| Left to deduct in later years | — | $21,200 |
| Years until it is fully deducted | — | 27.5 |
| Tax saved this year, at 32 percent | $7,040 | $256 |
$6,784 of tax, decided by a classification. The improvement column is not a lost deduction, it is a deferred one. But money in year one is worth considerably more than the same money spread across twenty-seven, and a landlord who was counting on the deduction to offset this year’s rent does not get it. Figures are illustrative and rounded; the first year is smaller still, because the mid-month convention gives a partial year.
Where the invoice usually lands
Most of the arguments are about the same dozen items. This is where they normally fall, with the reason attached. The reason matters more than the answer, because the next invoice will be slightly different.
| The work | Usually | Why |
|---|---|---|
| Patching a section of roof after a leak | Repair | Keeps the building in ordinary operating condition |
| Full roof replacement | Improvement | Restoration. A major component replaced |
| Repainting between tenants | Repair | Maintains; it does not better or adapt |
| Servicing the HVAC on a schedule | Repair | Routine maintenance, expected to recur |
| Replacing the entire HVAC system | Improvement | Restoration. A major component |
| Replacing a broken water heater | Either | A repair by nature, and deductible outright under the de minimis election if the invoice is $2,500 or less |
| Replacing all the windows | Improvement | Betterment, or restoration of a large portion of a major component |
| Converting a garage into living space | Improvement | Adaptation. A new or materially different use |
| Refinishing existing floors | Repair | Returns the surface to its condition, without bettering it |
| Replacing floors throughout with a better material | Improvement | Betterment. Materially increased quality |
The three elections that settle most of it
Before arguing a classification, check whether an election makes the argument unnecessary. Each of these turns work that would otherwise be capitalized into a current deduction.
| Election | What it does | The limit |
|---|---|---|
| De minimis safe harbor Reg. 1.263(a)-1(f) |
Deducts low-value invoices outright, whatever the classification would have been | $2,500 per invoice or per item. $5,000 if you have an applicable financial statement, which most individual landlords do not |
| Routine maintenance Reg. 1.263(a)-3(i) |
Deducts recurring work that keeps the building in operating condition | Work you reasonably expect to perform more than once in the ten years after the building is placed in service |
| Small taxpayer Reg. 1.263(a)-3(h) |
Deducts improvements on a small building, including work that fails the test above | Average annual gross receipts of $10 million or less, building unadjusted basis under $1 million, and total repairs plus improvements for the year no more than the lesser of $10,000 or 2 percent of that basis |
The small taxpayer election is the one most often missed. On a building with an unadjusted basis of $400,000, the ceiling is 2 percent, or $8,000, and a landlord who spent $7,500 across the year on work that was technically improvements can deduct all of it, per building, by making the election.
Where people get this wrong
Treating the price as the test. A $600 repair to a structural component can be an improvement and a $9,000 exterior repaint can be a repair. Size is evidence of nothing; the test is what the work did to the building.
Judging the component instead of the building. The regulations ask whether the work improved the building as a whole, not whether it improved the thing that was worked on. Replacing three of thirty windows does not restore the building; replacing all thirty does.
Deciding after the year closes. The de minimis and small taxpayer elections are made on a timely filed original return. Discovering them in March, while preparing a return for a year that ended in December, means discovering them a year late.
Forgetting that improvements come back at sale. Capitalized work is depreciated, and depreciation is recaptured when the property sells. See depreciation recapture on the sale of rental property. The deduction you take now reduces basis and raises the gain later.
What to do about it
Ask the contractor to itemize. One line reading “renovation, $40,000” forces a single classification onto work that was probably several jobs. An itemized invoice lets the repairs be deducted and the improvements be capitalized separately, which is both more accurate and usually better.
Make the de minimis election every year. It costs nothing, it applies to invoices you have not yet received, and without it a $2,400 appliance goes on a depreciation schedule for five years.
Check the small taxpayer ceiling before December. If you are near the limit, the timing of one more job decides whether the whole year’s work is deductible.
Keep the depreciation schedule current. Improvements are separate assets with their own placed-in-service dates. Our guide to calculating depreciation on a rental covers how they are added, and land always stays its own line item.
Frequently asked questions
Is a new roof a repair or an improvement for a rental property?
A full roof replacement is an improvement. It is a restoration under the regulations, because the roof is a major component of the building, and it is capitalized and depreciated over 27.5 years. Patching a section after a leak is a repair and is deducted in the year paid. The distinction is the extent of the work, not the reason for it: a roof replaced because it was failing is still a replacement.
Can I deduct repairs on my rental in the same year I pay for them?
Yes. Genuine repairs are deducted in full in the year paid, on Schedule E. See Publication 527. The question is only whether the work is a repair. Where it is not, one of the three elections may still allow a current deduction, and each has to be made on a timely filed original return.
What is the de minimis safe harbor limit?
$2,500 per invoice or per item for a taxpayer without an applicable financial statement, which covers most individual landlords, and $5,000 with one. It is an annual election and it applies whatever the classification would otherwise have been, so a $2,400 appliance is deducted rather than depreciated.
Is replacing a water heater a repair or an improvement?
Usually a repair, because a single water heater is not a major component of the building in the way a whole plumbing system is. If the invoice is $2,500 or less the de minimis election deducts it either way, which is why that election is worth making before the question arises.
