What do I need if I call the IRS?

If you call the IRS, they'll need to verify you. Be prepared with:

Your Social Security Number or Individual Taxpayer Identification Number
Your filing status (Single, Head of Household, Married Filing Jointly, or Married Filing Separate)
Your prior-year tax return (they may ask you questions from it to verify your identity)
A copy of the tax return you’re calling about
Any letters they may have sent you
Paper and pen to take notes—make sure to write down the day you called and the name and ID number of the agent you spoke to, plus any instructions or deadlines you were given.

Jot down your questions before calling and be prepared for delays. It may take over an hour to get your call answered.
