The IRS collects federal income taxes and enforces tax law, but also administers programs that affect homeowners directly

The Internal Revenue Service is the federal agency that collects income taxes from individuals and businesses, and it enforces the tax code. For most people, that is their only interaction with it. But the IRS also runs programs that touch homeownership: it processes the Earned Income Tax Credit, manages retirement accounts like IRAs, oversees tax deductions for mortgage interest and property taxes, and handles disputes when you disagree with a tax bill.

Understanding what the IRS does — and what it does not do — helps you know when to contact it, when to contact your lender or local assessor instead, and what documents you will need. The IRS does not set property tax rates, approve mortgages, or insure deposits. It does enforce rules about what you can deduct, how rental income is taxed, and whether you owe back taxes that could affect your ability to refinance or sell.

Key Takeaways

  • The IRS collects federal income tax and enforces tax law, but does not handle property taxes, mortgage approval, or homeowners insurance.
  • Homeowners can deduct mortgage interest and property taxes on their federal return if they itemize, but the rules and limits change year to year.
  • If you earn rental income from a property you own, the IRS requires you to report it and allows you to deduct certain expenses against it.
  • Back taxes owed to the IRS can result in a lien on your home and may prevent you from refinancing or selling without paying first.
  • The IRS has payment plans and hardship programs for people who cannot pay their full tax bill at once.

What the IRS taxes and what homeowners can deduct

When you own a home, the IRS allows you to deduct mortgage interest and property taxes from your federal income tax return — but only if you itemize deductions instead of taking the standard deduction. For most homeowners, this choice depends on whether your total itemized deductions (mortgage interest, property taxes, state and local taxes, charitable donations, and medical expenses) exceed the standard deduction for your filing status that year.

You cannot deduct homeowners insurance premiums, HOA fees, utilities, maintenance, or repairs. You also cannot deduct principal payments on your mortgage — only the interest portion. The IRS publishes the current standard deduction amounts each year, and tax software or a tax preparer can help you decide which route saves you more money.

If you rent out part or all of your home, the IRS requires you to report that rental income on your tax return. In exchange, you can deduct expenses directly tied to the rental: mortgage interest (the rental portion), property taxes (the rental portion), repairs, maintenance, utilities, insurance, and depreciation. You cannot deduct personal use of the property or capital improvements that add value to the home.

How the IRS handles disputes and back taxes

If you disagree with an IRS bill or believe you were assessed incorrectly, you have the right to dispute it. The IRS will send you a notice explaining the issue and giving you a deadline to respond. You can request an appeal, provide additional documentation, or work with a tax professional to challenge the assessment. The process can take months or years depending on the complexity.

If you owe back taxes and do not pay, the IRS can place a tax lien on your home. This lien is a legal claim against your property, and it becomes public record. A tax lien makes it very difficult to refinance, sell, or borrow against your home because lenders will not lend on a property with a federal lien. The IRS can also garnish wages or seize bank accounts to collect.

If you cannot pay your full tax bill, the IRS offers payment plans and hardship programs. A payment plan lets you pay over time; an Offer in Compromise may allow you to settle for less than you owe if you can show genuine financial hardship. These options require you to contact the IRS directly or work with a tax professional, and they do not remove the lien until the debt is paid in full.

The difference between the IRS and your local tax assessor

Many homeowners confuse the IRS with their local property tax assessor. They are separate agencies with different jobs. Your local assessor determines the value of your property for property tax purposes and sets the rate your city or county charges. The IRS does not do this. The IRS only cares about your property tax bill insofar as you may deduct it on your federal return.

If you disagree with your property tax assessment, you appeal to your local assessor or county board of appeals — not the IRS. If you want to deduct your property taxes on your federal return, you report the amount you actually paid to your local government on your IRS tax return. The two systems are separate, and problems with one do not automatically affect the other.

Retirement accounts and the IRS

The IRS oversees retirement savings accounts like traditional IRAs, Roth IRAs, and SEP IRAs. These accounts have tax advantages: money you contribute may be deductible, and the money grows tax-free until you withdraw it. For homeowners, this matters because you can borrow against some retirement accounts (like a 401(k)) to fund a home purchase, though doing so has tax consequences if you do not repay the loan on time.

The IRS also enforces rules about when you must begin withdrawing from retirement accounts (usually at age 73 for most accounts), and it taxes withdrawals as ordinary income. If you are under 59½ and withdraw early, you generally owe a 10 percent penalty plus income tax, though there are exceptions for first-time homebuyers (up to $10,000 lifetime from an IRA) and certain hardships.

When to contact the IRS versus other agencies

Contact the IRS if you have questions about deducting mortgage interest or property taxes, if you received a tax bill you disagree with, if you owe back taxes, or if you need a payment plan. You can reach the IRS by phone at 1-800-829-1040, through its website at irs.gov, or by mail using the address on any notice you received.

Do not contact the IRS about property tax rates (contact your local assessor), mortgage approval (contact your lender), homeowners insurance (contact your insurance company), or HOA disputes (contact your HOA or local housing authority). The IRS handles federal income tax and related matters only. If you are unsure whether the IRS is the right agency, start with the agency that sent you the notice or bill — they will direct you if needed.

How the IRS affects your ability to buy or refinance

A tax lien or unpaid back taxes can prevent you from refinancing or selling your home. Most lenders run a lien search before approving a mortgage, and they will not lend if a federal tax lien is on record. Similarly, when you sell a home, any federal tax lien must be paid from the sale proceeds before you receive your share.

If you have back taxes and want to buy or refinance, you have options: pay the full amount, set up a payment plan with the IRS, or pursue an Offer in Compromise. Some lenders will work with you if you have an active payment plan in place and are current on payments. A tax professional or mortgage broker can help you understand your options and what the IRS will require.

Frequently Asked Questions

Can I deduct my mortgage payment on my taxes?

You can deduct the interest portion of your mortgage payment, not the principal. You also must itemize deductions on your tax return rather than taking the standard deduction for this to save you money. Property taxes are also deductible if you itemize. A tax preparer can tell you whether itemizing or taking the standard deduction saves you more.

What happens if I owe the IRS money and want to sell my house?

The IRS can place a lien on your home, and that lien must be paid before the sale closes. You can pay the full amount, set up a payment plan, or request an Offer in Compromise. The sale proceeds will go toward the tax debt first, and you will receive what remains. Contact the IRS or a tax professional to discuss your options before listing.

Does the IRS set my property tax rate?

No. Your local city or county assessor sets property tax rates and determines your home's assessed value. The IRS only allows you to deduct the property taxes you pay on your federal income tax return. Questions about your property tax bill go to your local assessor, not the IRS.

Can I use my IRA to buy a house?

First-time homebuyers can withdraw up to $10,000 lifetime from a traditional or Roth IRA without the 10 percent early withdrawal penalty, though you will still owe income tax on the withdrawal from a traditional IRA. You can also borrow against a 401(k) if your plan allows it. Withdrawals or loans have tax consequences, so consult a tax professional before taking money out.

How do I set up a payment plan with the IRS?

Contact the IRS at 1-800-829-1040 or visit irs.gov to request a payment plan. You will need to provide information about your income and expenses. Short-term plans (120 days or less) may not require a setup fee, but longer plans typically charge a fee. A payment plan does not remove a tax lien, but it may help you refinance if you stay current on payments.
