Section 210 Reduction of a section 208 penalty for co-operation
United Kingdom
Where—
P is liable to pay a penalty under section 208 of the amount specified in section 209(1),
the penalty has not yet been assessed, and
P has co-operated with HMRC,
HMRC may reduce the amount of that penalty to reflect the quality of that co-operation.
In relation to co-operation, “quality” includes timing, nature and extent.
P has co-operated with HMRC only if P has done one or more of the following—
provided reasonable assistance to HMRC in quantifying the tax advantage;
counteracted the denied advantage;
provided HMRC with information enabling corrective action to be taken by HMRC;
provided HMRC with information enabling HMRC to enter an agreement with P for the purpose of counteracting the denied advantage;
allowed HMRC to access tax records for the purpose of ensuring that the denied advantage is fully counteracted.
But nothing in this section permits HMRC to reduce a penalty to less than 10% of the value of the denied advantage.
