Now or later....For example, you're probably aware that when an invoice is raised it's usual to include it in Turnover. If the invoice is not paid by your year end, it will increase your Profits for tax purposes. Hopefully by the time the tax is due, normally 9 or 10 months after the year end, you've been paid so you're not losing out on cash flow.
However, you may not be aware that if as a shareholder in your SME company you rearrange your shareholdings by giving away shares to family non-spouse members or employees, tax can be due on you.
That doesn't make sense!
