Definition & Meaning

Form 505, known as the Injured Spouse Claim and Allocation, is a tax form used by individuals in a married filing joint status to claim their share of a joint tax refund. This form is applicable when a portion or all of a tax refund is applied to their spouse's past-due financial obligations, such as federal tax, state income tax, child support, or federal non-tax debts, without the injured spouse's consent or agreement. The goal is to separate the financial liabilities, ensuring that the non-debtor spouse receives their rightful share of the refund based on their income and contributions.
