Consultancy and tax payments

Hi, I undertake consultancy for pharmaceutical industry and am paid a fee. I declare this on a self assessment at the end of the year. Can tax be paid when the fee is paid, rather than waiting until the end of the year?

Hi
There is no formal method of you paying tax in advance like this.  You could of course make payments to your self assessment account, say on a monthly basis or set the tax aside in a bank account each month, so that you can pay the payments on account when they become due.
