The rule in plain words

What to do if your return fails it

1. 01Open the tables below and find the cells the rule reads.
2. 02Add up the parts in your return and compare the result with the total.
3. 03If they differ, a part is missing, a value sits in the wrong cell, or the total is out of date.
4. 04The Bank of England allows a small rounding difference, worked out from the decimals each value is reported with.
5. 05It runs only when your filing indicators mark C13.01.01 and C14.01.01 as reported.
6. 06This is a warning. It does not stop the return on its own, but your supervisor may ask you to explain it.

The cells it reads

Which returns it applies to
