turnover and tax deducted

[mighty]

Just going through my 1st years corporation tax return and I have a question.

When calculating my turnover in profit and loss, do I include tax on labour which I have already been deducted, even though I didn't receive it?

I assume it is thus, though it seems that i will be paying tax on tax this way.

turnover = (all income received at bank + tax deducted for labour content of invoices by main contractors) - flat rate vat paid

Sorry if this appears dumb..

Your gross sales will include any tax already deducted. You'll receive a credit for all the tax that was deducted.
