When submitting T5013 slips and summaries, partnerships may encounter an error message that reads, “Filer number is missing or invalid for this type of return.”
This error occurs when the Canada Revenue Agency (CRA) does not have an RZ program type registered for the partnership. It may affect T5013 slips and summaries. It does not affect T5013FIN transmissions.
To prevent filing delays, the partnership or authorized filer may proactively contact the CRA to create an RZ program account for the partnership.
