Optimising Starter Savings and Dividend allowances

[NothankyouSir]

Hi experts,

Am I correct in thinking that Dividend earnings do not affect the availability of starter savings allowance? If so, are you able to send a link eg from HMRC that shows this?

My client wishes to do the following as she has substantial savings income. Exact value unknown, but likely to be approaching £6k. Does the below comp work please, and if not, why not?

12,500 - Salary from their business (fully covered by 2020/21 personal allowance)
6,000 - interest income (fully covered by starter savings allowance of £5,000 (as earned income is not above £12.5k) plus £1,000 personal savings allowance)
31,500 - dividend income (£2,000 is covered by Dividend allowance, remainder taxed at 7.5%)

50,000 - total income

Tax to pay:

Nil on salary
Nil on Interest
£2,212.50 - tax to pay on £29,500 of dividends

Any dividends over this value would be taxed at 32.50%.

Your help is much appreciated!
