Questions about MTD deadlines
Is a quarterly update a tax return?
No. It is a summary of income and expenses sent through compatible software; year-end obligations still remain.
Can software set an earlier cut-off?
A provider may ask for records before the statutory deadline so it can process the update. The HMRC deadline remains the legal backstop.
