Very poor. Inaccurate software and unhelpful support.

Very poor. I tried to use this for a simple self-assessment return. I have three partnerships - it only offered me the forms for one. Two were non-trading over the past year so I continued. CGT rates changed mid-year and it didn't take that into account - tried to calculate the tax on the highest rate. Completely wrong. I switched to another software provide and their package got to the same answer as me - less than half the figure from 123e-filing. Wouldn't go near them again.

Prompt service

I was unable to submit my return due to a problem with my HMRC credentials but they contacted me by email and were able to submit my return. I'd paid for an assisted service and they were very prompt in reviewing my return before I made the changes they advised. My return was successfully submitted.

Submission unsuccessful, No refund

From the beginning I've told them that it's my first time doing this on my own instead of using the accountant. After filling out the data and PAID, the submission to HMRC wasn't successful. The help chat told me my password to the Gateway number was wrong for having a special digit and asked me to change it. I did and received a new Gateway number. The submission still didn't work. It's near the deadline. He then said I needed to activate something which needs a code to be mailed from HMRC to me. It would be very tight with the deadline. I needed to get the accountant to do it after all. They won't refund it. So be warned before you pay!!.I have screenshot the latest conversation with their chat person. You should always do it from the beginning as they disappear to avoid accountability.

This service used to be good - waste of time now

This service used to be good. Now it does not recognise a password no matter how many times it is changed in line with your instructions. It is a total waste of time. It costs me more in lost time than I pay in subscription. 123 reg NEVER recognises a changed password, even when it is right in front of me and there are no errors in the wording. You ask me which day it was a problem! IT'S EVERY DAY

Hi Jacqueline,

We're really sorry to hear about the ongoing issues you've had with logging in and it’s certainly not the experience we want for our customers.

We’d like to get this sorted for you as quickly as possible. As we haven’t been able to locate any recent support requests from you, could you please contact us directly with your support PIN so we can investigate the password issue properly.

You can reach our support team here: https://www.123efiling.co.uk/

Once we have a few details, we’ll be able to check what’s causing the login failures and get everything working again.

Thank you for bringing this to our attention, and again, our apologies for the inconvenience this has caused.

The software couldn’t be more easy unless you are an idiot like me! But thankfully the customer service & advice via email and chat couldn’t be more helpful or patient! A massive thank you all round! Heres to next year!

Frustrating experience - beware! 3 attempts = 3 x money taken

Having moved abroad, I have to use one of the HMRC approved online companies to submit my tax return. I had to make a small amend to my bank account name as it did not include the whole name. I contacted their chat to be told I would have to resubmit and pay them £18 again. So I did (albeit not happily!). Same problem again. Then I get told '& is not supported in this box, please enter and instead' but there is no such instruction on their website. Nor was there an error message to say the "&" was not compatible and to use a different format. I had another issue earlier on trying to remove a page - the link they told me to press didn't exist. 5 -6 attempts and it just wasn't there. Then another link they put in the chat is no longer valid - HMRC changed it 3 months ago. So they're not keeping up to date with HMRC website - just happily charging £18 per submission even if the amend is just one letter!!! NEVER AGAIN! Will use one of the others in future.

Dear Michael

You have paid the second subscription payment after submitting your return. As per chat history you were requested to email our accounts team for a refund request. We offered to apply the duplicate payment as credit, depending on your preference. We later issued a full refund via PayPal, and we're sorry if it felt like you had to chase this up. Our intention was never to withhold your money or twist facts — we simply offered a credit as a faster option while still leaving the choice to you.
Please email us if you have any further questions.

Kind Regards
123 e-Filing Team

I’ve been using 123e-filling for my self-assessment and tax returns for the past few years. The initial year was a bit confusing when it came to using the assisted service, but the subsequent years were quite straightforward once I understood how the site functions. The responses are always prompt, and I genuinely appreciate the service.

I live in South Africa and have used this service for several years now. My experience has been fantastic every time. They check and return your forms and reply to any e mail correspondence incredibly quickly (I have even sent a query outside of working hours - they responded within a few minutes!) In terms of my personal experience, I would highly recommend them and I will continue to use them in the future!
