Understanding Your CP285 Notice
CP285 notifies BMF taxpayers the reason their Form 1128, Application To Adopt, Change, or Retain a Tax Year, was denied.
What you need to do
Continue filing your annual income tax return on the tax year you have historically used. If you are a new entity, use the tax year assigned when you received the notice of EIN assignment (CP575, 576, etc.).
