Improvement Versus Repairs

Every time you pay a contractor or buy materials for your rental property, you face the exact same tax dilemma: Can I deduct this today, or do I have to depreciate it over decades? Yeah, sure, decades as in plural sounds dramatic, but it’s true- 27.5 or 39 years. Decades.

The answer lies in understanding the difference between a routine repair and a capital improvement. According to IRS Revenue Ruling 2000-4,

Section 263(a) and § 1.263(a)-1(a) provide that no deduction is allowed for any amount paid out for permanent improvements or betterments made to increase the value of any property or estate. Section 1.263(a)-2(a) provides that capital expenditures include the cost of acquisition, construction, or erection of buildings, machinery and equipment, furniture and fixtures, and similar property having a useful life substantially beyond the taxable year.

Cool. The things you buy that have a useful life substantially greater than one year are considered a capital expenditure (capex) and must be capitalized in most situations. What the heck is capitalized? Is this a grammar thing?

There is capitalization in finance, and perhaps even in the deal structure on your rental property (debt versus cash versus investors). In accounting, and in tax return preparation, capitalization is an accounting method in which a cost is included in an asset’s value and expensed over the asset’s useful life, rather than expensed in the period the cost was incurred. Capitalization recognizes a cash outlay as an asset on the balance sheet rather than an expense on the income statement.

Yup, full on geek-speak.

Moreover, a capital improvement is an expenditure that increases a property’s value, useful life, or adapts it to a new use. The IRS often refers to these as betterments, restorations, and adaptations, or BRA for short. Fun!

Simply put, you can either expense or capitalize a purchase:

• Expensing the purchase is an immediate deduction and therefore an immediate reduction in rental income.
• Capitalizing the purchase requires listing the asset on your fixed asset schedule and slowly expensing it over time through depreciation.

Accelerated depreciation through bonus depreciation or Section 179, or both, can allow for an immediate deduction of an otherwise capital asset. We’ll talk about accelerated depreciation and Section 179 expensing in a bit.

Rental Property Repairs Safe Harbors

There are three safe harbors relevant to rental property owners and real estate investors. If your expenditure fits into one of these three categories, you can bypass the complex rules repairs versus improvements, expensed versus capitalized, and immediately deduct as an expense. Heck you might even get to collect $200 as you pass Go.

Here are the safe harbors. We will expand in nauseating detail later in the chapter:

• De Minimis Safe Harbor: The easiest one. If an item or invoice line-item costs $2,500 or less, you can generally expense it immediately.
• Small Taxpayer Safe Harbor: If your building’s unadjusted basis is $1 million or less, and your total annual maintenance and repairs (which includes cleaning, by the way) stay under $10,000 or 2% of the building’s basis, whichever is more restrictive, you can expense all of it.
• Routine Maintenance Safe Harbor: If you reasonably expect to perform this exact maintenance on a building system more than once every 10 years to keep it in normal operating condition, you can expense it.

Ok, neat. How do you use them? There is a 5-step process and just like the safe harbors, we will do a deep dive into each:

The 5-Step Repair Or Improvement Process

If your expenditure doesn’t neatly fit into a safe harbor, things get a bit more complicated. Here is the step-by-step roadmap to land at either expense or capital improvement:

• Step 1: De Minimis or Small Taxpayer Safe Harbor: First, you check the easy buttons like a stroll through Staples. Is your individual expenditure small enough to fit into the safe harbors that we just defined above?
• Step 2: Unit of Property (UoP) Analysis: Before you can test a repair, you must determine whether you are measuring the fix against the entire building structure or just one of its specific internal systems (like the plumbing or HVAC). Under the regulations, building systems like plumbing, HVAC, and electrical are treated as separate units of property from the building structure, which is why this step matters so much.
• Step 3: Routine Maintenance Safe Harbor: The 10-year rule. Next, test the repair against the system you defined in Step 2 to see if you expect to perform this maintenance more than once a decade. Water heaters is a wonderful example.
• Step 4: Betterment or Adaptation: The “dead in the water” tests. If your work materially increases capacity, strength, efficiency, or quality, it is called a betterment. Bad. Alternatively, if your work adapts the property to a totally new use, it is called an adaptation. Both are bad since they generally require you to capitalize. Also, the IRS loves to argue betterment when restoration is unclear, so even something that feels like a repair can get pulled into capitalization if there is any meaningful upgrade.
• Step 5: Restoration Guideline: The final gauntlet. If you made it this far, then functional tests are applied along with a “30%ish heuristic” to see if you merely repaired a system or completely replaced a major, critical component.
