Tips for next year
Consider filing your taxes electronically. Filing online can help you avoid mistakes and find credits and deductions that you may qualify for. In many cases you can file for free.
What to do next
- Write down the date on the letter today.
- Look the number up on irs.gov yourself. Don’t trust a link or phone number from anyone else.
- If it says you owe money or proposes changes to your return, take it to a licensed CPA, EA or tax attorney before that date.
