Spouse back taxes liability and relief options

Key Takeaways

  • Joint returns generally create joint and several liability. The IRS can collect the full amount from either spouse.
  • Filing separately typically limits liability to your own return, but community property rules may still allocate income/tax.
  • Debt timing matters: pre-marriage debt is usually separate; post-marriage depends on filing status and state law.
  • Four relief paths exist: Innocent Spouse, Injured Spouse, Separation of Liability, and Equitable Relief.

Understanding Back Taxes

Back taxes are unpaid taxes from a prior year that accrue penalties and interest. Unresolved balances can lead to liens, levies, and wage garnishments.

If you’re seeing offsets or IRS notices addressed to both spouses, review your filing history and consider speaking with a professional about resolution options.

Who’s Liable? Filing Jointly vs. Separately

Married Filing Jointly

Both spouses are jointly and severally liable for tax, penalties, and interest on the joint return—even if one spouse caused the issue.

Married Filing Separately

You’re generally liable only for your own return. However, credits can be limited and community property rules may still allocate income/tax.

Timing: Before vs. During Marriage

Debt incurred before marriage is usually separate. Once married, liability depends on filing status and, in some states, community property rules.

Offset example

When filing jointly, your refund can be applied to your spouse’s past-due debts through Treasury Offset. If part of the refund was yours, consider Injured Spouse Allocation using Form 8379.

Community Property States

In community property states, income earned during marriage is generally shared. Filing separately may still require reporting half the community income.

Relief Options for Spouses

Innocent Spouse Relief (Form 8857)

If your spouse understated income or claimed improper items without your knowledge, you may be relieved from joint liability. Deadlines apply.

Learn about Innocent Spouse Relief

Injured Spouse Allocation (Form 8379)

Protect your portion of a joint refund from being used to pay your spouse’s separate debts (e.g., child support, student loans, prior taxes).

Separation of Liability

If divorced, legally separated, or living apart, the IRS can allocate the understated tax between spouses based on responsibility.

Equitable Relief

If the other programs don’t fit but holding you liable would be unfair, the IRS may grant relief based on all facts and circumstances.

If you still owe after relief, explore options like Installment Agreements, Offer in Compromise, or Penalty Abatement.

What To Do Next

  1. Confirm filing history and balances with IRS transcripts.
  2. Document debt timing (pre‑ vs post‑marriage) and your state’s property rules.
  3. Assess which relief path fits; note deadlines (e.g., Form 8857 timing).
  4. Plan a resolution if balance remains: payment plan or settlement.
  5. Consult a professional if you receive notices or offsets.

Audit Representation can help if your return is examined.
