You can lower the chances of being investigated

Only a very small percentage of investigations are random, so if you are picked the chances are that you’ve done something to attract the attention of HMRC.

This may be that your income is dramatically up and down or that returns are always late, or that you are claiming excessively high expenses in proportion with your income - all these things can make you high risk in the eyes of HMRC. It’s like you are jumping up and down screaming, “pick me, pick me”.
