Very professional service, very prompt and customer first mindset. Kah was kind enough to make himself available almost at any sort of time it suited me to work around my work commitments, to be able to communicate. He was patient explaining and answering all my questions. I was relieved to find somebody who is professional, who was able to help me with submitting a tax return with just few days left before the closing Jan deadline and also at very reasonable and fair price. Thank you and looking forward to work together again

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.

Was in a tight spot and required immediate help before a deadline with my small company's accounts and tax return. Basetax (Kah Tan) answered my livechat questions very promptly (considering the hour of the day) and helped me through the process within the hour. Great and clear communication, very responsive, answered questions and we submitted everything before the deadline. I will definetely be using their services again in the future. I have also found the app very clear, useful and straightforward for bookkeeping. Will continue using it from now on.

Thank you!

I have used Basetax for several years and am extremely pleased with their efficiency and personal interest. Any questions I have needed answering have always received a swift and helpful response.
The online programme is easy to navigate and upload your income records to. I have tried alternative more well known software but found them to be confusing, whereas Basetax meets all my financial recording requirements perfectly.
As for submitting my annual tax return, it’s a breeze.
I thoroughly recommend you give Basetax a try, you won’t be disappointed.

This would be our third year using basetax as our accounting software. Now I'm quite picky when choosing accounting software but you can't really go wrong with these guys. Simple to use, many functions for sole traders, partnerships and more. Customer service via the webchat is the best I've ever used. A response is very quick with Kah & the team working tirelessly to deal with any queries we may have.

Customer Testimonials

This is an absolutely fantastic accounts program. Very straightforward, accurate along with excellent customer service! I would recommend Basetax to any business!


I used Basetax to complete my annual tax return after leaving the UK. I found the site's online service simple to use and was very pleased with the way it guided me through the process step-by-step. For me though, what set's the service apart and really stood out was the level of support. I made a few mistakes in my submission and needed to make a few amendments. I found the support (from Kah) friendly, kind, quick and very helpful - I felt he really went beyond the level of service you get from almost any online service.
I have no hesitation whatsoever in using Basetax again in the future and I heartily recommend them to everyone!


Excellent as ever, prompt & reliable service - thank you Kah


First time I used Kah and I have been so impressed with his speed and efficiency. He has made everything very clear for us and we will definitely be using him again.


Great people to deal with really helpful,
Very knowledgeable in there field. They have made my day much simpler for running my business.
Can't thank them enough.


100% recommend Mr Kah Tan! Extremely swift and clear communication. Lightening fast service. Eloquent and informed. Incredibly reasonably priced! Keeps it simple and hassle free. Absolute hero. Thanks for all your help!


Basetax & Kah are supporting my tax return for many years and taking all the troubles away. Also the transition from Sole-Trader to LTD went very smoothly. I highly recommend Basetax!


Excellent service and speedy response. Would highly recommend...


Hi have been using Basetax for several years now, as I am only running a small partnership business I can’t afford the accountant costs.
A simple easy way of keeping track of your books.
The service is always friendly and quick if you are stuck with anything.
I would definitely recommend them!


I've completed two sole trader/self assessment returns and received great advice with Kah. He offers a speedy and efficient service, I recommend him.
