“Last Return Made Up To”: What does it mean?

The Companies House webcheck and our very own company admin portal both have a “Last Return Made Up To” field which is sometimes followed by a date. So what does this mean?

All annual returns have a “made up to date”; this is the date that the annual return is correct up to. The “Last Return Made Up To” field simply reflects this date. If the field is empty the limited company has not yet filed an annual return.
