Renting Your Home Office to Your Business

What This Actually Is

A self-rental arrangement is a transaction between two separate parties — your business as the tenant, and you personally as the landlord. That distinction matters.

This isn't a home office deduction on your personal return. It's a formal landlord-tenant relationship between you and a business you own. The IRS treats it that way, and your documentation should too.

Done right, it's legitimate and defensible. Done carelessly, it creates problems that outlast the deduction.

The Lease Agreement

No written lease means no defensible arrangement. The agreement should look like something two unrelated parties would actually sign — because that's the standard the IRS applies.

It should cover:

• The specific space being rented and its square footage
• Monthly rent, payment terms, and lease dates
• Permitted use — business purposes only
• Signatures from both parties

The rent needs to be reasonable. Look at comparable commercial rates in your area and document how you landed on the number. A figure that can't be explained by market data won't survive a challenge.

The space itself needs to meet standard home office requirements — used regularly and exclusively for business, and either your principal place of business or a space where you meet clients. If the space doesn't qualify on those terms, the arrangement doesn't hold up regardless of how clean the lease looks.

How It Flows on Your Return

The business deducts the rent as a business expense. Straightforward.

On your personal return, the rental income goes on Schedule E and is offset by real deductible expenses — depreciation on the office portion, a pro-rated share of utilities, insurance, and other allocable costs. When those expenses absorb the income, the business has taken a clean deduction and the personal tax impact is minimal. That's the appeal.

The expenses have to be real and documented. Not estimated, not inflated.

Depreciation and What Happens When You Sell

Depreciating the office portion of your home is a legitimate expense that offsets the rental income — but it reduces your cost basis in the home, and that has consequences later.

When you sell, two things happen on the business-use portion:

The primary residence exclusion requires analysis. The gain exclusion available to homeowners may not fully apply to the business-use portion — particularly if you rented the space to your business for more than three years. This is worth reviewing before you sell, not after.

Depreciation taken gets recaptured. Every year of depreciation you claimed comes back as taxable income on the sale, at rates up to 25%.

This isn't a reason to avoid the arrangement. It's a reason to understand what you're trading. The annual deduction has real value — but so does the recapture waiting at the back end, especially in an appreciating market.

A Few Practical Notes

The payments need to actually happen. The business should be transferring rent each month. A deduction with no corresponding cash movement doesn't hold up.

Document the space. Photos, a floor plan, or a written description of the dedicated area all help if questions come up later.

Revisit annually. If the rent hasn't been reviewed in years or the lease has never been updated, it starts to look less like an arm's-length transaction and more like an arrangement of convenience.

Get the setup reviewed before you start. The interaction between the Schedule E treatment, depreciation, and your home's eventual sale is specific to your numbers. The structure works — but only when the details are handled correctly from the beginning.
