Left School at 10 years old. Used an accountancy service once a year at a cost of £990 just to do my return and companies house filing. This year I spend a couple of hours on ChatGpt and WeFile. Sent WeFile several questions including over the weekend and after hours. Great response times, clear wording, and was able to file the both for £25. Could have saved myself about £4950 If Id run across this company and taxen the leap from year one. Highly recomended.Wefile was suggested by GemWefile was suggested by Gem, my AI chum and so glad he did. It was so damn easy and filing to both Companies House and the dreaded HMRC was so seasmless. Fantastic value tooWeFile is…pricelessI discovered WeFile through word of mouth, and choosing this platform was a life-changing decision for me as a solo entrepreneur. The innovation and efficiency of the software are truly impressive, providing a user-friendly experience that completely removes the stress of CT600 and Companies House filings.
The process is clear, logical, and guided, making it painless to submit everything correctly without the typical hustle. For someone who does not deal with these filings every day, that clarity was particularly valuable.
The difference in productivity is also staggering. I was able to complete in just two weeks the work that my previous accounting firm struggled with for six to seven months. After endless emails and calls, my old accounting firm had only managed to finish half of what I achieved on my own using WeFile myself.
The most important? Filing my company's corporation tax return took a few minutes!
If you want to sleep peacefully at night without worrying about the efficiency of an accounting firm or dealing with unpredictable charges, WeFile is a must-have. It is an absolutely brilliant solution for any UK limited company director. So, I highly recommend it. Kudos!Brilliant!Brilliant!

Also I had a couple of queries on a Sunday and they came back to me right away.Great experience I messed up the dates…Great experience I messed up the dates but then after contacting was made very clear with a step by step guide to get it corrected. Will defo use againSO fast, simple and cost-effective!SO fast, and a fantastic alternative for small biz owners stressed over the HMRC website taking their online filing away. It's legit, way easier than HMRC's direct service and way more cost effective than the monthly-subscriptions and even most per-filing alternatives.
I submitted my return through them and got an email from HMRC saying it got accepted a minute after Wefile confirmed. Really recommend!Very satisfiedI have used this service to file CT returns. It's easy to use and is excellent value for money
The easiest way to file your taxesThe easiest way to file your taxes, everything works as it should, and the pricing is incredible. It makes your life easy as everything is straightforward.Easy to use and great valueI was happy to find this very reasonably priced service to file my simple company accounts.
Using WeFile is probably easier than the original HMRC filing that was discontinued.
The site is well designed and the online help is useful.
There was one area of confusion that the help cleared up for me. When carrying losses forward only one box is shown (labelled "160"). However, on the HMRC site there is also box 285. The help said that the losses are allocated correctly -- against trading profits or total profits, which the software did correctly. A minor improvement would be to label the box "160/285" so that users don't end up looking for box 285.
That said, I was happy to find and use the WeFile website.Very good£ £25 to fileVery good£ £25 to file, fast and straight forward enough not being an accountant, highly recommended.Absolutely brilliantAbsolutely brilliant. I do my own business accounts and when HMRC decided to go digital, I thought, crikey accountancy fees, monthly subscriptions on platforms. But, after finding your application, its was nice and easy.

Recommendations A+++ for the small companies.Good value, straightforward and easy to useI was very pleased with WeFile. The process was clear, logical and much easier than I had expected. The system guided me through the filing step by step, highlighted anything that needed attention, and made it relatively painless to complete and submit everything correctly.
I also used ChatGPT alongside the process as a guide and independent check, which gave me extra confidence that I understood each step correctly. The combination worked very well.
For someone who does not deal with these filings every day, that clarity was particularly valuable. I would happily use WeFile again and would recommend it to other small company directors.The best of all!Having tried several approved agencies, all of which were very complicated with hidden restrictions, I found WeFile absolutely brilliant. Very easy to use, very reasonably priced and straightforward. Filing my company's corporation tax return took a few minutes! Great set up!Simple and straight forward…Simple and straight forward instructions.
It was as close as damit to replicating the way previously I submitted accounts to HMRC. Highly recommended to anybody with a small company filing.
The only question I would ask is why HMRC have added this layer of complexity to the process.Very good experienceVery good experience. Went from registering to submitting to HMRC and CH very quickly. The import from Quickbooks was a very slick feature that really helped. I had one difficult disallowed expense and capital loss to enter and was able to figure out how to enter it with the help of Google AI Mode. Fairly priced for the job at £29. I hope it stays that way. Excellent overall!I submitted a CT600 with s413 notesI submitted a CT600 with s413 notes. There was a section for a s455 (CT600A) too, which I paid substantially more for on another platform. Stands its ground against more expensive services.
I used Claude AI to guide me through and everything was very simple with the combination of the two.
Like other platforms, I was able to review the docs before they were submitted.
Each return I did was sucessfully submitted and accepted by HMRC.
I sent a few support tickets for clarification and received a timely response for each one, including minor updates to their system.
