Some of it. Older income tax debt can be discharged in Chapter 7 only if it passes the three-year, two-year, and 240-day timing rules and was not fraudulent. Payroll taxes, trust-fund penalties, fraud penalties, and recent taxes generally cannot be discharged.
The return was due at least three years ago, you filed it at least two years ago, and the IRS assessed the tax at least 240 days ago. All three must be true, along with no fraud or willful evasion, for that tax year to be dischargeable in Chapter 7.
It can. Bankruptcy may erase your personal obligation to pay a qualifying tax, but a lien already recorded against your property can remain attached to that property. That difference between personal liability and a property lien surprises many filers.
Chapter 7 can discharge qualifying older income tax outright. Chapter 13 instead folds what you owe, including taxes that cannot be erased, into a three to five year repayment plan. Which fits depends on your income, your assets, and how recent the tax debt is.
People facing both tax debt and bankruptcy often hear two opposite things: that bankruptcy wipes out taxes, and that it never touches them. The truth sits in between. Some income tax debt can be discharged, but only if it passes specific tests.
In a Chapter 7 bankruptcy, older income tax debt can be wiped out only if it meets all of these conditions, generally summarized as:
Miss any one of these and that tax year usually cannot be discharged. The rules exist so people cannot run to bankruptcy court the moment a bill arrives.
Several kinds of tax debt are off the table no matter the timing. Payroll taxes and trust-fund penalties, the part of employment taxes withheld from employees, are not dischargeable. Fraud penalties are not dischargeable. Recent income taxes that fail the timing tests stay too. And a tax lien already recorded against your property can survive the bankruptcy even when your personal liability for the debt is wiped out, which is a distinction that catches people off guard.
Chapter 7 can discharge qualifying older income tax outright. Chapter 13 works differently: it reorganizes what you owe into a three to five year repayment plan, which can include nondischargeable taxes paid over time, often without further penalties piling up. For someone with recent tax debt that cannot be erased, Chapter 13 is sometimes the more useful tool because it buys structure and time.
Bankruptcy is a serious step with lasting credit effects. Before going there for tax debt alone, it is worth comparing the IRS's own programs, an installment agreement, an Offer in Compromise, or currently-not-collectible status. We cover those in the tax relief guide, the Offer in Compromise guide, and what to do if you cannot pay.
One detail sinks a lot of cases. If you never filed a return for a tax year, that year's tax generally cannot be discharged, even decades later. A substitute return the IRS files on your behalf usually does not count as you filing it. So someone who skipped filing during hard years can find those exact debts are the ones bankruptcy will not touch. Filing the missing returns, even late, can start the clock that eventually makes the debt dischargeable.
