Important Notice: Federal Payments Going Digital
Beginning Sept. 30, 2025, the federal government will stop issuing paper checks for tax refunds and most other payments. Refunds will be issued electronically (direct deposit, prepaid debit cards, or digital wallets).
What you should do:
- File your return as usual—no changes.
- Confirm your bank account details with your tax preparer securely.
- Explore electronic payment options for federal taxes. Watch the IRS video or visit the IRS Payments web page.
Paper payments remain available for now, but transitioning early will make things easier. We expect to receive updated information regarding all electronic payments from the IRS in the next few months.
