How to do a compliance check: data-gathering powers: overlap with other powers
You should use the data-gathering powers to collect data for risk assessment.
For the purpose of checking the tax position of data-holders and for specific tax checks you must use Schedule 36 FA 2008 information powers.
Data-gathering powers only allow you to send the notice to the relevant data-holder, see CH28410. If the person is not a relevant data-holder then you must consider the use of Schedule 36 FA 2008 information powers.
