Losing a parent is overwhelming, but the IRS doesn’t pause for grief. Long after the funeral, unexpected tax issues can surface—quiet, complicated and costly. Knowing what’s coming makes all the difference. Here’s what often gets missed when emotions run high and paperwork stacks up fast.
Death Doesn’t Erase IRS Debt
Taxes owed at the time of death don’t disappear automatically. The IRS can still come after the estate to collect what’s due, and heirs often find their inheritance delayed by old debts. If left unresolved, some tax bills can hang around for years.

Final Tax Returns Must Still Be Filed
Even after someone passes, their final tax return (Form 1040) must be filed. It includes income earned right up until the day they died. Skipping this can bring penalties. And yes, filing is required even when there’s no tax owed.

Estates May Be Required To File Income Tax Returns

Tax Liens Can Transfer With Property

Unreported Pre-Death Income Triggers IRS Attention

Social Security Overpayments Are Reclaimed
If benefits continue after someone passes, they legally must be returned. Sometimes, the SSA automatically withdraws the funds, but not always. Beneficiaries who unknowingly spend that money can be held responsible, and it’s one of the most frequent financial issues after death.

Prior Gifts May Trigger Gift Tax
The IRS reviews gifts over $18,000 (2024 limit) for tax compliance, and executors may need to file Form 709 for sizable pre-death gifts. If records are missing, retroactive penalties might follow. A full review of recent gifts should be part of the process.

State-Level Inheritance And Estate Taxes Still Apply

Life Insurance Can Inflate Taxable Estate Value
Payouts from life insurance aren’t taxed as income, but they do raise the estate’s total value. If that pushes the estate past the federal exemption limit, tax liability can follow. It’s best to set up an Irrevocable Life Insurance Trust (ILIT) to help reduce this potential problem.
