Quick and simple service, although communications with the tax advisor were somewhat sketchy and the first draft came back incorrect due to a miscalculation with my p11d. Only resolved when i questioned the figures. The concerning part of the process however was with payment - i received a link to make a payment £50 higher than the price agreed. When i questioned this, the advisor informed me via email midway through November that 'prices had gone up due to exceptional demand'! I checked the simpltax website, and guess what, the advertised prices hadnt changed. It felt like a very poorly executed attempt to get more money from me and that type of behaviour just isnt professional. When challenged, he returned the invoice to the correct amount,but this left a really bad taste. I wouldnt use them again.
