What is Form 1128?

Taxpayers use it to change their tax year end date. It must be approved before they can use the new date. Partnerships, S corporations, personal service corporations (PSCs), or trusts may be required to file it to adopt or retain a certain tax year.

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.

Not advice. Not a filing. Verify with a licensed professional. Rules change by year and facts.
