James has made a prompted disclosure of a careless inaccuracy. The PLR is £12,000.
Step 1
The percentage for the quality of the disclosure (a) has been calculated as 60%.
Step 2
The maximum penalty (b) is 30% and the minimum penalty (c) is 15%.
So the maximum disclosure reduction (d) is 30 – 15 = 15
Step 3
The actual reduction percentage for disclosure (e) is 15 x 60% = 9%
Step 4
Penalty percentage to be charged (f) is 30% – 9% = 21%
Step 5
The penalty to be charged (g) is £12,000 x 21% = £2,520
