Renting Your Building to Your Own Business? Whether You Need a Lease Depends on Your Structure.

A lot of business owners end up in this exact setup: you own the building, your business operates out of it, and the “rent” is really just money moving between two entities you control. It feels informal because, in a sense, you're paying yourself.

Whether that needs to be papered with a full lease agreement depends heavily on what's on the other end of that arrangement. There's a real difference between an S-corp (or C-corp) leasing space from a separate LLC you own, and a single-member LLC where you're simply claiming a home office deduction. The first genuinely needs a lease. The second usually doesn't.

Where a Real Lease Matters: S-Corp (or C-Corp) Paying Rent to a Related LLC

When an S-corp or C-corp leases space from a real estate LLC you also own, it's tempting to skip the lease agreement altogether — after all, who's going to enforce it? But a real, signed lease between the two entities does work that a verbal understanding can't:

It keeps the entities legally separate.

One of the most common ways courts pierce the liability protection between related companies is by finding that the owner didn't actually treat them as separate businesses — no lease, no defined terms, funds moving back and forth without documentation. A properly executed lease is concrete evidence that the real estate entity and the operating business are exactly what they claim to be: two distinct entities transacting at arm's length. Skip it, and you've handed a future creditor or opposing lawyer an argument that the corporate veil should be ignored entirely — for both entities.

It protects the arrangement if either entity changes hands.

If you ever bring in a partner, sell the operating business, or transfer the property, a documented lease is what makes the relationship transferable and defensible. Without it, a buyer's attorney will flag the gap immediately — and it becomes a negotiating point that costs you leverage.

It sets terms that actually make sense for your business.

A real lease lets you define rent, term length, responsibility for repairs and taxes, and what happens if the operating business needs to downsize, relocate, or wind down. Without that, you're left improvising terms after a disagreement has already started — the worst time to be negotiating.

What a Related-Party Lease Should Cover

At minimum, a lease between your own entities should address:

• Rent amount and how it's set — ideally at a defensible market rate, not an arbitrary number

• Term and renewal — even a simple annual term with renewal options

• Maintenance and tax responsibility — who pays property taxes, insurance, repairs

• Default and exit provisions — what happens if the operating business can't pay, or wants out early

• Signatures from both entities — signed by the appropriate authorized person for each, not just one signature “on behalf of everyone”

Where a Full Lease Is Usually Overkill: Your Own LLC and a Home Office

The math changes when there's no S-corp or C-corp in the picture — for example, a single-member LLC where you work out of a home office and want to take the home office deduction. In that setup, the “landlord” and the “tenant” are, for tax purposes, treated as the same person, and the IRS doesn't require a formal lease agreement to support the deduction. What it actually requires is regular and exclusive use of the space for business, documented square footage, and accurate recordkeeping (via the simplified method or actual-expense method on Form 8829).

Drafting a full commercial lease for that arrangement doesn't add legal protection you don't already have as a single-member LLC owner, and it doesn't change your tax treatment — it's just extra paperwork solving a problem that isn't there. The corporate-veil concern that makes a lease essential in the S-corp/LLC scenario above largely doesn't apply here, because there's no second entity's liability shield at stake.

The line to watch for: if that single-member LLC later elects S-corp tax treatment, or if you're renting space to a corporation rather than simply claiming a home office deduction as a sole proprietor or disregarded LLC, you've crossed back into the situation above — and it's worth revisiting whether a real lease is now needed.

A Word on the Tax Side

There's real financial upside to structuring a self-rental arrangement correctly — but the depreciation, loss treatment, and how the IRS views these related-party transactions is tax territory, not legal territory. That side of the analysis belongs with your CPA or tax advisor. Our role is making sure the lease itself is properly drafted, reflects genuine arm's-length terms, and holds up if it's ever scrutinized — by a court, a buyer, or the IRS.

The Bottom Line

If an S-corp or C-corp you own pays rent to a related LLC, treat it like any other commercial lease — because legally, it is one, and skipping it is what puts your liability protection at risk. If you're a single-member LLC simply claiming a home office deduction, save yourself the paperwork — that's a documentation question, not a lease question.
