What This Notice Means

The IRS changed your tax return because it believes there's a miscalculation. After the changes, there's an overpayment on your account.

What to Do

  • Read the notice carefully. It explains the changes.
  • Compare the figures on the notice with your return.
  • If you agree, correct the copy of the return you kept for your records. You don't need to take further action.
  • If you disagree, contact the IRS within 10 days from the date of the notice.

Your Refund

If you haven't received it already, your refund of the overpayment should arrive within four to six weeks. Two conditions apply:

  • You owe no other taxes or debts the IRS is required to collect.
  • The refund is $1 or more.

If six weeks pass, you don't owe anything else, and the refund hasn't arrived, call the toll-free number on your notice.

If You Disagree

The window is 10 days. Call the toll-free number on the notice, or mail the completed contact stub with your correspondence or documentation. Keep copies and send by certified mail.

An overpayment can still be the wrong number. If you expected a larger refund than the notice shows, compare carefully. To find out what caused the change, call the number on your notice.

Next Year

  • Check the return instructions for required documentation.
  • Attach all required forms and schedules.
  • Consider filing electronically to reduce math errors.
