Before you fax

  • Form 14950, Premium Tax Credit Verification, lists the documents to send. Complete a copy of Form 8962, Premium Tax Credit, too.
  • Send all your documents at the same time, and make sure they are easy to read.
  • The IRS prefers its Document Upload Tool; fax is the next option, then mail to the address at the top of the notice.
  • With a CP06 the IRS holds all or part of your refund until the audit is complete.
  • Need more time or help? Call 866-897-0161.
