Much depends on when in the tax year the company is wound up/struck off.
Either income or gains are added to income arising in the year, so, generally, a higher rate of tax applies to Income distributions than capital distributions of £200k.
Since March 2012, it has been possible to take £25k cash out of a company on winding up under s1000 Companies Act 2006, and have treated as a capital gain.
The balance would be treated as a dividend. The conditions for this treatment is that the company clears out all debts and liabilities and does not trade again.
So, even without any other income received in a tax year, in 2012/13, Income Tax will be £56468 and CG tax £1140 ie total £57608. However if the company were to be formally liquidated, even under a voluntary liquidation, all distributions would be capital distributions, so the tax bill would be around £19000 (with a liquidators bill typically in range £2500 to £3500 on top).
However, the above presupposes that the CGT Entrepreneurs Relief (ER) will be available. ER is aimed at trading entities, so there cannot be too much investment income in the company. As a rule of thumb, if more than 20% of the balance sheet is represented by active investments (which would not include current account balances), then no ER is due.
The effect of this is to increase the CGT bill to £49595. So, on balance, a formal liquidation seems the best bet.
