I recently submitted a request via my ASA to change a client's VAT periods to bring them in line with their 31st march year end. Having recently submitted their 31st May return I then asked to change them to March, June, etc. Got a confirmation email telling me to wait two days. Heard nothing. Log back into ASA and I can see that the VAT periods are now Match, June, etc. on their VAT certificate but on checking the next return due it is the quarter to 31st August.
This is the first time I have attempted this since MTD and it hasn't worked out as expected. In the old days I seem to think they would normally ask for a one month return to the end of June. Is it possible I have missed the boat and instead they expect the August return followed by a one-month return for September, then a full quarter on the new periods starting December.
I'd appreciate any members' experiences!
