Real Estate Depreciation: How It Reduces Your Tax Bill

Depreciation is one of real estate's most powerful tax advantages. Learn how it works, how to calculate it, and why it can turn a cash-flow-positive property into a paper loss.

Depreciation is one of the most powerful, and most misunderstood, tax advantages of real estate investing. It allows you to deduct a portion of a property's value every year as a “paper loss,” potentially reducing your taxable rental income to zero even when you are cash-flow positive. Here's how it works.

What Is Depreciation?

The IRS allows residential rental property owners to “depreciate” the value of the building (not the land) over 27.5 years, assuming it wears out over time. This is called straight-line depreciation.

Annual Depreciation = (Purchase Price − Land Value) ÷ 27.5

If you pay $275,000 for a property and the land is assessed at $50,000, your depreciable basis is $225,000. Annual depreciation = $225,000 ÷ 27.5 = $8,182.

How Depreciation Reduces Your Tax Bill

Say the same property generates $18,000/year in rental income and has $10,000 in cash operating expenses. Without depreciation, your taxable income is $8,000. With the $8,182 depreciation deduction:

Rental income$18,000

Operating expenses−$10,000

Depreciation deduction−$8,182

Taxable income−$182

A property generating real positive cash flow shows a paper loss of $182 for tax purposes. That loss may offset other passive income or carry forward.

Depreciation Recapture: The Catch

When you sell the property, the IRS recaptures the depreciation you've taken at a flat 25% tax rate (depreciation recapture). This means the tax benefit is deferred, not permanent. However, strategies like a 1031 exchange allow you to roll proceeds into another property and defer both capital gains and depreciation recapture indefinitely.

Depreciation rules involve passive activity loss limitations, cost segregation studies, and state-specific variations. This article provides a general overview and is not tax advice. Always consult a CPA or tax professional for your specific situation.

Key Takeaways

1Depreciation lets you deduct the building's cost (not land) over 27.5 years, reducing taxable income.
2A cash-flow-positive property can show a paper loss for tax purposes. This is a major advantage of real estate.
3Depreciation is deferred, not forgiven: when you sell, the IRS recaptures it at 25%.
4A 1031 exchange can defer both capital gains and depreciation recapture when reinvesting.
