Optional offline planning aid, not a tax return or filing confirmation.
Keep completed notes securely; never include passwords or one-time codes.

WORK THROUGH THIS EXAMPLE
Two businesses show outstanding work, but records are ready for only one. List the obligations separately, identify each missing period and agree a catch-up date with the filer. Keep the eventual submission confirmations so an overdue label is resolved with evidence.
