What Are Fannie Mae’s Guidelines on IRS Taxes Owed?

If you owe back taxes, Fannie Mae’s guidelines on IRS taxes owed let you qualify for a conventional mortgage in one of two ways: pay the balance in full at or before closing, or show an approved IRS installment agreement that you’re current on and count the monthly payment as a debt in your DTI. Which path you’re on depends on a single question: has the IRS recorded a Notice of Federal Tax Lien in the county where the property sits?¹

The Lien-in-County Test

Everything turns on whether a Notice of Federal Tax Lien has been recorded in the county where you’re buying.

If no lien has been recorded there, you can include the monthly installment agreement payment as a regular debt obligation in your debt-to-income ratio, alongside a car payment or student loan. The tax balance does not have to be paid off before closing.²

If a lien has been recorded in that county, the entire tax debt must be paid in full at or before closing, even if your installment agreement is valid and current.¹

The practical result surprises people. You can owe the IRS $40,000 and still qualify for a Fannie Mae loan if no notice has been filed in the right county and your paperwork is in order. But the moment that notice shows up in the county’s public records where your new home sits, the math changes completely.

A federal tax lien itself arises automatically once the IRS assesses a liability, sends a bill, and doesn’t get paid on time. That underlying lien is invisible to the public. What Fannie Mae cares about is the Notice of Federal Tax Lien, the public filing recorded in the county that alerts other creditors.³

Qualifying With an IRS Installment Agreement

When no Notice of Federal Tax Lien exists in the subject property’s county, the lender can treat your IRS payment as a monthly debt obligation. To do that, the underwriter needs two documents.²

First, a copy of the approved IRS installment agreement showing the repayment terms, including the monthly payment amount and the total balance owed. That’s the letter the IRS sends after approving your plan.

Second, evidence you’re current on your payments. Fannie Mae accepts the most recent payment reminder from the IRS as proof, as long as it shows the last payment amount and date along with the next payment due. At least one payment must have been made before closing.²

With both in hand, the underwriter uses the actual monthly payment from the IRS agreement to calculate DTI. That payment stacks alongside your projected mortgage, car loans, student loans, and other obligations. A $300 monthly IRS payment on $5,000 in gross monthly income eats 6% of your DTI capacity, which is often enough to matter. Run the numbers before you start shopping.

One narrow exclusion: the installment payment can be left out of DTI entirely if someone else has been making the payments and you can document a 12-month history of that arrangement with no late payments.² Uncommon, but worth knowing if a family member has been covering it.

If You Can’t Document the Agreement

Without either the approved agreement or proof you’re current, the installment path closes. The lender must then require the full outstanding balance to be paid at or before closing under Fannie Mae’s rules for unresolved debts.² There’s no fallback calculation. You produce the documents or you pay off the debt.

The 5 Percent Rule Does Not Apply

You may see advice claiming a lender can calculate 5% of the outstanding tax balance as a substitute monthly payment when the installment agreement paperwork is incomplete. That’s a misreading. Fannie Mae’s 5% rule applies to revolving credit accounts, such as credit cards and lines of credit, where the credit report doesn’t show a required minimum payment.² For an IRS installment agreement, the actual agreement payment is the only figure the underwriter can use.

When You Have to Pay the Balance in Full

Two situations force full payoff at or before closing.

The first is a recorded Notice of Federal Tax Lien in the property’s county. Fannie Mae requires payoff of delinquent taxes, tax liens, and any liens that could affect its first-lien position, and an active installment agreement doesn’t override that when the notice is on record where you’re buying.¹ After you pay the debt in full, the IRS is required to release the lien within 30 days.³ Build that timeline into your closing schedule.

The second is owing the IRS without a formal installment agreement in place. Delinquent taxes fall under the broader category of delinquent credit that must be resolved at or before closing.¹ Acknowledging the debt isn’t enough. Either pay it, or set up an agreement, meet the documentation requirements, and take the DTI path.

Expect the underwriter to find whatever the IRS knows. Lenders pull IRS transcripts as part of standard income verification, and those transcripts show assessed liabilities, penalties, and recorded liens along with your filing history.⁴ If the transcript reveals a tax liability you didn’t disclose, everything pauses until the status of that debt is resolved. Transcript surprises are one of the most common reasons closings get delayed for borrowers with tax issues.

Options if a Notice of Federal Tax Lien Is Already Recorded

A recorded notice doesn’t always mean you have to pay the whole balance. Two IRS procedures can change your footing.

Lien Withdrawal at $25,000 or Less

If you owe $25,000 or less and set up a Direct Debit installment agreement, the IRS may withdraw the Notice of Federal Tax Lien. If you owe more, you can pay the balance down to that threshold first, then request withdrawal.³ Withdrawal is different from release: it removes the notice from public records as if it had never been filed. For Fannie Mae, that can shift you out of the “must pay in full” category and into the “include the monthly payment in DTI” category.

Subordination via Form 14134

In limited circumstances, the IRS may agree to subordinate its lien so the new mortgage lender takes the senior position. You apply using Form 14134, Application for Certificate of Subordination of Federal Tax Lien, and you should submit it at least 45 days before your expected closing date to allow review time.⁵

The IRS grants subordination only when doing so will either result in the government receiving a payment equal to the lien amount or will ultimately increase its ability to collect the debt.⁵ The application requires a property deed or title, a current title report, and a proposed closing statement. Success isn’t guaranteed. Borrowers with the funds often find full payoff more practical.

What to Do Before You Apply

Order matters. Pull your own IRS account transcript first to see exactly what the IRS has on file, including whether a Notice of Federal Tax Lien has been recorded and where. You can do this through your IRS online account.

If no notice has been filed and you already have an installment agreement, gather your agreement letter and most recent payment reminder showing you’re current. That package is what the lender needs to count the payment as a monthly obligation instead of demanding full payoff.

If a notice has been recorded in the county where you plan to buy, your realistic options are to pay the full balance, pay down to $25,000 and request withdrawal, or apply for subordination through Form 14134 at least 45 days before your target closing date.⁵ None of these move quickly. Start early.

If you don’t yet have an installment agreement, set one up first. Apply through the IRS website or by calling the IRS directly. For balances under $50,000, the online application takes minutes. Once it’s approved and you’ve made at least one payment, you have what the lender needs.²
