Well i paid my accountant ?250 plus vat so ?300 in total.
This was just to file my tax returns and go through all expenses with me, my expenses came to ?13,000 ad he manged to claim 75% of my car purchase, petrol, car repairs etc which i wasn't claiming and also makeup, laptop etc.
So well worth ?300!
He also gives you a advice for a year, so you can ring him up if you have any questions regarding something. All in with the price.
I paid the money once he submitted my tax returns (i used to do it myself online) but didn't get a monthly payment option. Remember also your accountant fees are also tax deduct able, so you can claim them as an expense against your tax.
