The rule in plain words

There is at least one fund/matching portfolio reported in Table 2 of IR.01.03 that is not reported in Table 1 of IR.01.03

What to do if your return fails it

  1. 01Open the tables below and find the cells the rule reads.
  2. 02The check applies only when its first part holds in your return. When it does, the second part must hold too: fix the second part, or correct the first.
  3. 03It runs only when your filing indicators mark IR.01.03 as reported.
  4. 04This is a blocking check. A return that fails it is normally rejected, so fix it before you submit.
