Renting Equipment to Your Own Business: A Tax-Saving Move (Unless You’re an S Corp)

If your business relies on trucks, machinery, tools, or other expensive equipment, you’ve probably heard about renting equipment to your business through a second company you also own. It’s a legitimate strategy that can lower your tax bill — but the benefit depends heavily on how your operating business is taxed, and if it’s an S corporation, the math often doesn’t work the way people expect.

How renting equipment to your business works

You form a second entity (often an LLC) to hold the equipment — construction equipment, medical devices, commercial kitchen equipment, vehicles, specialized tools — and lease it to your operating company at a fair market rate, backed by a written lease. The operating company deducts the rent; the rental entity reports the income. Done well, this can separate valuable assets from operational liability, simplify depreciation tracking, and in some structures, reduce the income subject to self-employment tax.

Where the self-employment tax savings come from

If your operating business is a sole proprietorship, single-member LLC, or partnership, its net profit is generally subject to self-employment tax — 15.3% on top of ordinary income tax. Shifting a portion of that income into equipment rental payments moves it out of the self-employment tax base, since equipment rental income is often treated differently than active trade or business income. For equipment-heavy businesses like contractors, landscapers, and trucking companies, that difference can add up every year.

Why it usually doesn’t help if you’re an S corp

If your operating company is already an S corporation, you’re not paying self-employment tax on its profits in the first place — only on the reasonable salary you take as an employee. The rest passes through as a distribution, already exempt from self-employment tax. So renting equipment to your own S corp doesn’t unlock new savings; it just moves income between entities you own, adds the overhead of a second entity and lease agreement, and can draw more IRS attention.

The self-rental trap

Regardless of entity type, the IRS’s “self-rental” rule (Treasury Regulation 1.469-2(f)(6)) reclassifies rental income as nonpassive when you materially participate in the business you’re renting to — but a loss from that same activity stays passive. That asymmetry means the income can’t be sheltered by passive losses from other activities, while losses stay locked up. (See IRS Publication 925 for the full mechanics.) It applies whether the operating business is an S corp, C corp, or partnership.

The loss side isn’t entirely wasted, though: since it stays passive, it can offset other unrelated passive income you have (another rental property, a limited partnership interest) dollar for dollar, with no cap. It just can’t offset the same activity’s recharacterized income, and if you have no other passive income to absorb it, it suspends and carries forward until you do — or until you dispose of the activity.

What actually matters when renting equipment to your business

Before setting up (or unwinding) an arrangement like this, it’s worth checking:

• Whether your operating business’s profit is even subject to self-employment tax today.
• Whether the rent can be documented as a genuine fair-market rate — the IRS can recharacterize below- or above-market rent between related parties.
• Whether the self-rental passive activity rules will limit how you can use any losses.
• Whether the cost of a second entity — filings, a bank account, bookkeeping — is worth the tax benefit.

Every business’s situation is different, and structuring decisions like this can ripple into payroll, depreciation, and your overall return.
