Married taxpayers often choose to file joint tax returns because of the higher standard deduction amounts, marginal tax rates thresholds, and other benefits. One aspect of joint filing that taxpayers are sometimes unaware of is that both taxpayers are jointly and severally liable for the taxes due, as well as any penalties or interest that are imposed by the IRS.
Joint and Several Liability for Tax Debt
Joint and several liability means that the IRS can go after either taxpayer (or both) for the full amount of the tax debt. Even if you later divorce, the IRS can go after you for tax debt from previous tax years when you filed a joint return.
