What to do if your return fails it
- 01Open the table below and find the cells the rule reads.
- 02Compare the values in your return. If the first is smaller than it may be, one of them is wrong: check both before you change either.
- 03The Bank of England allows a small rounding difference, worked out from the decimals each value is reported with.
- 04It runs only when your filing indicators mark C32.01.01 as reported.
- 05This is a blocking check. A return that fails it is normally rejected, so fix it before you submit.
