Dividend tax recovery through the client’s tax code

AAT is trying to establish if the following issue is widespread:

I have a client whose tax code has been adjusted for dividend tax recovery from 1100L to 265L

He takes a maximum no NIC salary (£670 per calendar month) and £30k dividends.

Per HMRC the dividend tax reduction is £8,341. This will increase the tax collected under PAYE by £8,040-£2,659 = £5,381 which at 20% is equal to £1,076.20

My quick calculation says that tax due on £8,040 + £30,000 - £ 11,000 = (£ 5,000 @ 0%) + (£22,040 @ 7.5%) = £ 1653. This is an under-collection.

So, the HMRC recovery only works if the employee earns at least the personal allowance.

How will HMRC collect the under-recovery?
