These are some initial observations on a section-by-section basis.
The FA 2011 changes led to an initial fall in scheme use
However, the number of schemes reached the previous peak in 2013/14 but then started to fall away again
This was at the same time as HMRC began to co-ordinate its response to these arrangements.
HMRC’s evidence on their reg 81 powers is very misleading.
Under regulation 81 of the PAYE regulations, HMRC can transfer an Income Tax liability arising under the DR rules, which includes the underlying liability and the loan charge, to an employee where:
...
"• HMRC has issued a determination to an employer in respect of the liability; • the determination has become final; and • the employer has not paid the liability within 30 days."
There is a glaring omission in this statement.
HMRC’s evidence says “We are not aware of any public sector organisations actively promoting the use of DR tax avoidance schemes to their employees or contractors.”
This needs to be understood in the light of what I've heard from contractors.
