CT61 return reporting dates vs VAT reporting (non- standard quarters)

Dear Community Members, Our company is VAT registered, with reporting periods that end in April, July, October, and January. These are quarterly periods, but they do not align with the standard calendar quarters. I have a question regarding the frequency and periods for the CT61 return: should we use the same periods as we do for VAT, or do we need to follow the standard calendar quarters? Thank you for your assistance.

Hi,
Could you please direct your query to the  CT61 team, for which the telephone number is 03000 518371.
Thank you.
