When You Need to Contact the IRS?
Not all tax return errors require immediate action. Here are some examples when contacting the IRS is a good idea:
- You entered the wrong Social Security Number
- You forgot to report income (like a side gig or freelance work)
- You claimed the wrong filing status
- You need to fix dependent information
- You received a notice from the IRS that doesn’t match what you filed
- You accidentally omitted credits or deductions
If your error is a minor math mistake or missing a W-2 copy, the IRS will likely fix it on their own and notify you. But if the mistake changes your tax liability (amount owed or refund due), you may need to take action yourself—starting with a little communication.
