Tax Refund Seized? How the Treasury Offset Program Works and How Injured Spouses Get Their Share Back

The Treasury Offset Program lets the Bureau of the Fiscal Service withhold a federal tax refund to pay past-due child support, defaulted federal student and SBA loans, state income tax, and unemployment debts, in that priority order. Creditor agencies must mail a Notice of Intent to Offset at least 60 days before referral, giving you time to pay, sign a repayment agreement, or dispute the debt. When the debt belongs only to your spouse, Form 8379 Injured Spouse Allocation recovers your share of a joint refund in roughly 8 to 14 weeks.

A superseding return is a complete second return filed before the deadline (including extensions) that legally replaces your original, unlike a Form 1040-X amendment filed after it.

Form T2125 in 2026: How Canadian Sole Proprietors File Business Income, CPP, and NETFILE Without Triggering a CRA Review

Form T2125 turns a Canadian sole proprietor's invoices and receipts into taxable net business income on the T1 return. For 2026, gig platforms report earnings directly to the CRA, self-employed CPP totals nearly $9,300 at the earnings ceiling, and the June 15 filing extension still leaves payment due April 30.
