Depreciation for Rental Property Owners, Explained Simply

Depreciation is one of the most powerful tools available to rental property owners, and also one of the most misunderstood. Used correctly, it can reduce your annual tax bill by thousands of dollars while you simultaneously collect rent and build equity. Ignored, it leaves real money on the table every single year.

This explainer keeps things simple and focuses on the practical mechanics, not the accounting jargon.

What depreciation actually is

Tax authorities recognize that buildings physically wear out over time — roofs age, plumbing degrades, finishes deteriorate. Rather than make you wait until you sell to claim that wear-and-tear, they let you deduct a portion of the building's value every year you own it as a rental. That annual deduction is depreciation.

Land does not depreciate (it doesn't wear out), so depreciation applies only to the building itself, not the land it sits on. Most jurisdictions require you to allocate the purchase price between the two and depreciate the building portion over a defined number of years — typically 27.5 years in the US, around 40 years in many European jurisdictions, with significant local variation.

A simple example

Suppose you buy a rental property for $300,000, of which $240,000 is allocated to the building and $60,000 to land. With a 27.5-year schedule, you can deduct roughly $8,727 per year as depreciation against your rental income.

If your property produces $15,000 of net rental income before depreciation, the depreciation deduction reduces your taxable rental income to about $6,273. At a 30% marginal tax rate, that's roughly $2,618 in tax savings — money you keep without spending a single dollar.

Why people ignore it (and shouldn't)

Depreciation is non-cash. You don't write a check for it, and your bank account doesn't shrink. So newer landlords often forget to claim it or assume it's optional. It is not optional in most jurisdictions — when you eventually sell, the tax authority assumes you took the deduction whether you did or not, and recaptures it. So you might as well take it.

What about depreciation recapture?

When you sell a rental property, the depreciation you claimed gets "recaptured" and taxed, often at a higher rate than ordinary capital gains. This sounds scary but isn't — you've had years of tax savings while you owned the property, and the recapture is paid only at sale, often offset by exchange strategies that defer the tax further.

Get a professional involved

Depreciation interacts with cost segregation studies, passive activity rules, and your overall tax position in ways that genuinely require a qualified tax professional. The cost of one consultation is trivial compared to the savings of doing it right. If you own even one rental property and aren't talking to an accountant who specializes in real estate, you're almost certainly leaving money on the table.
