What our users say
about our service

Base Tax has been preparing my returns for four years now. I cannot speak more highly of the company. The pressure relieved even for my small return has been immeasurable. Thank you Kah! Another year - another great job done. Always efficient and on time.

Jill Larmer

I have been using Basetax for end of year accounts the past few years. Kah is a pleasure to work with, always delivers on time and offers great rates. Very professional and offers advice.

Armeri

Really quick and straightforward, took care of our microentity accounts and tax return in just a few days. Always reliable!

Charlie R

Basetax is an economical way to deal with HMRC - the book-keeping left to the client, the submission firmly in the hands of the accountant, advice all along the way. Kah Tan and his team work with great efficiency on the Return, and yet are always ready to fill gaps in the client's understanding, and even to offer general pointers.This has been a most successful relationship over two years.

Francis Sheppard

I have for months been struggling with the completion of my 2018 tax return but despite being fined £10.00 per day by HMRC for late submission I had buried my head in the sand. I came across Kah and I cannot recommend him highly enough. He answered all my questions, emails went back and forth, and within three days my tax return was submitted. I now intend to get my 2019 tax return completed ASAP and save myself the nervous breakdown 🙂
