(Hopefully) Quick question re tax rates on dividends

[Spoiler]

Say I want to take a dividend of £100k in this tax year. Is the whole lot (minus the £2k zero rated allowance) taxed at the Higher Rate of 32.5%?

Not knowing your personal circumstances - but you've already stated you have a significant warchest - I would ask if you really need to take £100k dividends this year ? If you don't need the cash, it may be more tax efficient to leave the money in the company only take what you need ?! Rinse and repeat next tax year...
