If you default on a HELOC, the consequences roll out in a predictable order: late fees, credit score damage, a frozen credit line, acceleration of the full balance, and eventually foreclosure on the home securing the loan. Even after the house is gone, the trouble can continue through a deficiency lawsuit for the shortfall and a tax bill on any balance the lender writes off. Understanding what happens if you default on a HELOC matters because the worst outcomes are avoidable at almost every stage, but only if you act before the lender’s options narrow.
The First 90 Days: Fees, Credit Hits, and a Frozen Line
Most HELOC agreements include a grace period of five to fifteen days after the due date. Miss that window and you’ll typically owe a late charge of $25 to $50, or a percentage of the missed payment. The fee gets added to your balance and starts accruing interest.
Once you’re 30 days past due, the lender reports the delinquency to the credit bureaus. That single notation can drop your score by 100 points or more, and federal law allows it to sit on your credit report for seven years from the date of delinquency.1Office of the Law Revision Counsel. 15 USC 1681c – Requirements Relating to Information Contained in Consumer Reports At 60 and 90 days, the lender updates the bureaus again, and each update signals to future creditors that the situation is getting worse.
The lender can also cut off further borrowing before you’re in formal default. Under Regulation Z, a creditor can freeze the HELOC or reduce the credit limit whenever it reasonably believes you won’t be able to meet your repayment obligations because of a material change in your financial circumstances, or when you’re already in default on a material term.2Consumer Financial Protection Bureau. 12 CFR Part 1026 Regulation Z – Section 1026.40 A falling home value can trigger a freeze on its own, even if you’ve never missed a payment. The lender must send written notice explaining why the line was suspended. Once frozen, you can’t draw new funds, and curing the default doesn’t automatically restore your original credit limit.
When Does a HELOC Officially Go Into Default
Federal law doesn’t set a specific number of missed payments. The trigger lives in your loan agreement. Under Regulation Z, a lender can terminate the plan and demand the full outstanding balance whenever you fail to meet the repayment terms spelled out in the agreement or when your actions put the lender’s collateral at risk.2Consumer Financial Protection Bureau. 12 CFR Part 1026 Regulation Z – Section 1026.40
In practice, most lenders don’t accelerate immediately. The typical pattern runs about three months of missed payments before the lender sends a formal breach letter demanding you catch up within 30 days or face acceleration. Don’t count on that cushion existing in your contract, though. Some agreements allow acceleration after a single missed payment. Others define default to include things beyond payments: letting homeowner’s insurance lapse, failing to pay property taxes, or damaging the property. Read the default and remedies section of your agreement before assuming you have time.
Your Right to Cure Before Foreclosure
This is the part most borrowers don’t realize they have. Many states, and most HELOC agreements, give you the right to reinstate the loan by paying all missed payments plus any fees and costs the lender has incurred. In a number of states, this right extends up to five days before the foreclosure sale, and some servicers accept payment right up to the sale date.
Reinstating costs far less than paying the full accelerated balance because you’re only covering the arrears rather than the entire outstanding loan. Even after a breach letter or notice of default arrives, the door is usually still open. Ignoring the lender’s notices and letting the cure period lapse is one of the most common and costly mistakes borrowers make.
Foreclosure and the Second-Lien Reality
If you can’t cure the default, the lender’s ultimate tool is foreclosure. It begins with acceleration: the lender invokes a clause demanding the entire outstanding balance at once. If you can’t pay, the lender records a Notice of Default in the public land records, which formally starts foreclosure.
Timing varies widely by state. Judicial foreclosure states, where the lender must go through court, can drag the process out a year or more. Non-judicial foreclosure states allow a trustee sale that can conclude in a few months. Either way, you’ll receive a Notice of Sale identifying the auction date before the property changes hands.
Why Some HELOC Lenders Don’t Foreclose
A HELOC is almost always a second lien, sitting behind your primary mortgage in the payment hierarchy. When the property sells, the first mortgage gets paid in full before a single dollar flows to the HELOC lender. If the sale price doesn’t cover the first mortgage, the HELOC lender recovers nothing from the property.
That priority structure often works in the borrower’s favor. When a home is underwater or has minimal equity above the first mortgage, foreclosing costs the HELOC lender legal fees for zero recovery. Many lenders in that situation charge off the debt and sell it to a collection agency instead. The debt doesn’t disappear; the fight simply moves from your house to your bank account and paycheck.
Deficiency Judgments: When Losing the House Isn’t the End
A deficiency is the gap between what you owe on the HELOC and what the lender actually recovers. In roughly 40 states plus the District of Columbia, the lender can sue you personally for that shortfall. A deficiency judgment converts what used to be secured debt into an unsecured obligation the lender can collect through wage garnishment and bank levies.
Federal law caps wage garnishment at the lesser of 25% of your disposable earnings or the amount by which your weekly pay exceeds 30 times the federal minimum wage.3Office of the Law Revision Counsel. 15 USC 1673 – Restriction on Garnishment For lower-income earners, the second prong can drop the cap well below 25%. Judgments are often renewable, so collections can continue for many years.
Some states have anti-deficiency laws that block lenders from pursuing borrowers after foreclosure, but these protections almost universally apply only to purchase-money mortgages, meaning the loan used to buy the home. HELOCs are non-purchase-money debt because the proceeds usually go toward renovations, tuition, or debt consolidation. That distinction leaves HELOC borrowers personally liable even after the property is gone, which is why a HELOC default can hurt worse than a first-mortgage default in states that otherwise limit deficiencies.
The window for the lender to file a deficiency lawsuit varies by state. Many set it at six years; others allow anywhere from ten to thirty years for claims tied to real property.
Taxes on Forgiven HELOC Debt
When a lender forgives part of your HELOC balance through a short sale, settlement, or post-foreclosure write-off, the IRS treats the forgiven amount as ordinary income. You’ll receive a 1099-C reporting the canceled debt and must include it on your federal return.4IRS. Publication 4681 – Canceled Debts, Foreclosures, Repossessions, and Abandonments On a $30,000 forgiven balance, that could mean several thousand dollars in unexpected tax.
For years, the qualified principal residence indebtedness exclusion allowed borrowers to exclude up to $750,000 in forgiven mortgage debt from income. That exclusion expired on December 31, 2025, and as of early 2026, Congress has not extended it.4IRS. Publication 4681 – Canceled Debts, Foreclosures, Repossessions, and Abandonments Anyone who settles or has HELOC debt forgiven in 2026 faces full tax liability on the canceled amount unless another exclusion applies.
The main remaining option is the insolvency exclusion. If your total liabilities exceed the fair market value of all your assets immediately before the cancellation, you can exclude forgiven debt up to the amount by which you were insolvent. You claim it by attaching Form 982 to your return.4IRS. Publication 4681 – Canceled Debts, Foreclosures, Repossessions, and Abandonments Because many borrowers defaulting on HELOCs are already financially strained, this exclusion applies more often than people expect. Debt discharged in a Title 11 bankruptcy case is also excluded from income.
Alternatives Worth Pursuing Before It Escalates
Foreclosure is expensive and slow for lenders too, so most would rather find another solution. If you’re falling behind, work through these options while you still have leverage.
- Repayment plan: the lender spreads your past-due amount across several months of higher payments, letting you catch up while keeping the account active.
- Forbearance: the lender temporarily reduces or suspends payments for a set period, after which you resolve the missed amounts through a repayment plan or modification.5FHFA. Loss Mitigation
- Loan modification: the lender permanently changes the loan terms by reducing the interest rate, extending the repayment period, or both.
- Short sale: you sell the home for less than the total mortgage debt. Both the primary mortgage lender and the HELOC lender must agree, and getting HELOC sign-off can be difficult because they’re last in line.
- Deed in lieu of foreclosure: you voluntarily transfer ownership to the lender instead of going through a foreclosure sale. The lender may still reserve the right to pursue a deficiency depending on the agreement.
A lump-sum settlement is another route, especially after a primary mortgage foreclosure has already wiped out the HELOC lender’s lien. At that point the lender holds unsecured debt with limited collection options, and many will accept 20 to 40 cents on the dollar rather than spend years chasing the full amount. Just remember that any forgiven balance above $600 will generate a 1099-C.
Bankruptcy as a Last Resort
Bankruptcy offers two paths, each with different consequences for the home.
Chapter 7 Discharge
Chapter 7 eliminates your personal liability on the HELOC. The lender can never sue you personally for the balance or garnish your wages. But the lien on the property survives. If you want to keep the home, you have to keep paying the HELOC even though you no longer owe it personally. Stop paying and the lender can still foreclose on the lien, though it can’t come after you for any deficiency.
Chapter 13 Lien Stripping
Chapter 13 can go further by stripping the HELOC lien entirely. This works only when the balance on all senior liens exceeds the home’s current market value. If it does, the HELOC is treated as fully unsecured because no equity backs it. The lien is removed, and the remaining balance joins your other unsecured debts in the repayment plan, typically paid at pennies on the dollar. If any equity exists above the first mortgage, even a small amount, the HELOC lien survives and lien stripping isn’t available.
Whatever path you’re considering, the earlier you engage with the lender or a housing counselor, the more options remain on the table. The right to cure, forbearance, and modification all become harder or impossible once foreclosure has been noticed and the sale date is set.
