Your LLC can pay your mortgage only if the LLC owns the property. If the home is titled in your personal name and your LLC writes checks to the mortgage company, the IRS treats those payments as taxable income to you, and the arrangement gives creditors a strong argument to pierce your LLC’s liability shield. The deed decides almost everything.
When the LLC Owns the Property
If your LLC holds title to a rental, a commercial building, or mixed-use real estate, the mortgage is the LLC’s obligation and the payments are ordinary business expenses. The LLC borrowed the money, the LLC owns the asset, and the LLC pays the debt from its own bank account. Interest on the loan and depreciation on the building are deductible.
This works only when the pieces line up. Title, loan, and bank account should all sit with the same entity. Rental income comes in, the mortgage goes out, and the LLC reports the net on its return or passes it through to your personal return if it’s a disregarded entity or partnership. Mix personal funds into that flow and you invite two problems at once: IRS scrutiny of the deduction, and the legal argument that the LLC is really just you wearing a different hat.
When You Personally Own the Home
This is where most owners get into trouble. If the deed and the mortgage are in your name, an LLC payment to the lender is not a business expense. The IRS will recharacterize it, and the label depends on how your LLC is taxed:
- For a single-member LLC (a disregarded entity) or a multi-member LLC taxed as a partnership, the payment is a distribution of profits. You owe income tax, and active partnership members owe self-employment tax on top.
- For an LLC that has elected S corporation or C corporation treatment, the payment looks like unreported wages or a taxable fringe benefit, and the company may need to issue a W-2 or 1099-NEC and remit employment taxes.
- For a C corporation LLC, the IRS can treat the payment as a constructive dividend, meaning the company gets no deduction and you still owe tax on the income.1Internal Revenue Service. Entities 1
Every version produces taxable income to you. If the payments went unreported, the accuracy-related penalty is 20% of the underpaid tax,2Office of the Law Revision Counsel. 26 USC 6662 – Imposition of Accuracy-Related Penalty on Underpayments and 40% for gross valuation misstatements.3eCFR. 26 CFR 1.6662-2 – Accuracy-Related Penalty
The Liability Shield You Just Lost
The tax bill is only half the damage. Routinely using LLC funds to cover personal expenses like a home mortgage is one of the strongest facts a creditor can point to when asking a court to pierce the corporate veil. Courts across the country treat commingling of personal and business funds as a central factor. Once the veil is pierced, the LLC’s separate legal existence is disregarded and your personal assets are exposed to business debts. The house the LLC was paying for becomes reachable in a lawsuit or bankruptcy.
Using an LLC to pay your personal mortgage is the same behavior that dismantles the protection the LLC was supposed to provide.
Transferring the Home Into the LLC
The obvious fix is to put the home in the LLC’s name so the LLC becomes the legitimate payer. In practice, this move creates three problems that usually outweigh the benefit.
Your Lender Can Call the Loan
Most residential mortgages contain a due-on-sale clause that lets the lender demand full repayment when you transfer any interest in the property. Federal law shields specific transfers from this clause: to a spouse, to a living trust where you remain the beneficiary, to a relative at death. Transfers to an LLC are not on that list.4Office of the Law Revision Counsel. 12 USC 1701j-3 – Preemption of Due-on-Sale Prohibitions Your lender is legally entitled to accelerate the entire balance the moment you record the deed.
Some servicers, particularly those following Fannie Mae guidelines, permit transfers to an LLC the borrower controls under specific conditions, and many lenders do not actively monitor for these transfers. “They probably won’t notice” is not a plan. If the lender does notice, the options are refinancing on worse terms, deeding the property back, or paying off the balance.
You May Lose the Home Sale Exclusion
When you sell a home you’ve lived in for at least two of the past five years, you can exclude up to $250,000 in capital gains from your income, or $500,000 for married couples filing jointly.5Office of the Law Revision Counsel. 26 USC 121 – Exclusion of Gain from Sale of Principal Residence The statute requires the taxpayer to own and use the home as a principal residence. If your single-member LLC is a disregarded entity, the IRS generally looks through it and treats you as the owner, which should preserve the exclusion.6Internal Revenue Service. Single Member Limited Liability Companies If the LLC has multiple members or has elected corporate taxation, the LLC is the owner for tax purposes and the exclusion almost certainly does not apply. On a typical home sale, that can mean tens of thousands of dollars in tax you would not otherwise have owed.
Transfer Costs and Title Insurance
Recording the deed costs roughly $10 to $50 depending on the county, and many states impose real estate transfer taxes ranging from a fraction of a percent to around 3% of property value. The deed type matters too. A quitclaim deed is cheap but may void your existing title insurance policy, which was issued to you personally rather than to the LLC. A warranty deed is more likely to preserve coverage. Confirm the effect with your title insurer before recording anything.
The Home Office Reimbursement Path
If you work from home and want the LLC to cover a portion of housing costs legitimately, an accountable plan is the tool. You pay the mortgage from your personal account, and the LLC reimburses you for the business-use share of your housing expenses. Done correctly, the reimbursement is not taxable income to you, and the LLC deducts it as a business expense.
An accountable plan has to meet three requirements: the expenses must have a business connection, you must substantiate them with records, and you must return any reimbursement that exceeds actual expenses.7eCFR. 26 CFR 1.62-2 – Reimbursements and Other Expense Allowance Arrangements Miss any of those and the reimbursement becomes taxable income.
The home office space itself must be used regularly and exclusively for business, and it must be your principal place of business or a place you regularly meet clients. A corner of your bedroom does not qualify. You divide the office square footage by the total square footage of the home to get the business-use percentage, then apply that percentage to mortgage interest, property taxes, utilities, insurance, and repairs. A simplified method allows $5 per square foot up to 300 square feet, capping the reimbursement at $1,500 per year with less paperwork.8Internal Revenue Service. Simplified Option for Home Office Deduction
This is not a route to full mortgage coverage. If the office is 15% of your home, the LLC reimburses 15% of eligible costs, not the whole payment. Keep the written plan, expense receipts, a floor plan showing the office, and reimbursement requests on file. Documentation is what keeps the arrangement a business deduction rather than a personal distribution the IRS will reclassify.
The Form 1098 Mismatch
Even when the arrangement is legitimate, interest reporting can get tangled. Lenders issue Form 1098 to individual borrowers, not to LLCs, partnerships, or corporations.9Internal Revenue Service. Instructions for Form 1098 If the mortgage is in your name and the LLC makes payments, the 1098 reports all interest as received from you. If the LLC owns the property but you personally guaranteed the loan, the 1098 may still list you.
When the numbers on your return don’t match the 1098, the IRS matching system flags it. Where more than one party pays on the same loan, attach a statement to your return explaining who paid what and how much each party is deducting.10Internal Revenue Service. Publication 936 – Home Mortgage Interest Deduction Missing that statement is a common audit trigger for small business owners running property costs through an LLC.
Rules That Keep the Arrangement Clean
Whether the LLC owns the property outright or reimburses you under a home office plan, a few habits prevent most problems.
- Match the deed to the payer. If the LLC is on the deed, the LLC pays from its own account. If your name is on the deed, you pay from your personal account.
- Keep separate bank accounts. One for business, one for personal, with no crossover. Commingling is the factor courts point to most often when piercing the veil.
- Put everything in writing. Operating agreements, reimbursement plans, and approvals for major expenditures. If it isn’t documented, the IRS and the courts will act as though it didn’t happen.
- Account for self-employment tax. Active LLC members owe SE tax on their distributive share, including guaranteed payments. Payments that get reclassified as income to you add SE tax on top of income tax.1Internal Revenue Service. Entities 1
An LLC paying a mortgage on property it owns is routine. An LLC paying a mortgage on property you own personally is always a taxable event and always a liability risk. The home office reimbursement route is the only legitimate middle ground, and it covers a slice of your housing costs, not the whole payment.
