This setting is available for editing only if all of the periods of the selected tax year have the Open status.

Note

If you change the VAT period type for a short tax year, the system will restore the length of the tax year to a full calendar year and will clear the Short tax year check box. If you need to change the VAT period type when some periods have been processed, select the Change tax report type check box.
Change VAT period type

A check box which makes it possible to change the VAT period type.

If the check box is selected, the VAT period type will be available and you can change to a different type, and the VAT periods will be recalculated for the open periods.

Changing from monthly to quarterly will change the open months 3 by 3 so if you have closed/prepared period 04 April you will have period 05 May and 06 June then 07 as July to September and 08 as October to December.

Note: If the remaining periods are less than wanted type, you can not change the type and you will get the error Remaining open periods does not match the VAT period type. Your selected type will be deleted. If you have created the next VAT year, this will be deleted so you can create it with the new settings. You will receive the message: Because the end date of the tax year has been changed, the subsequent tax years will be deleted. Please review and modify the next tax year settings if required.
