Customer Feedback

Here’s what current users are saying about GoSimpleTax’s tax return software and features:

Simon A

"Easy to use and submitting to the HMRC was seamless."

Jennifer Lynch

"Since discovering GoSimpleTax 6 years ago I was able to ditch my accountant and file my own tax returns. I am brain numb when it comes to taxes & self assessment but their software allows you to submit hassle-free without the complicated accountancy jargon that makes one usually feel disempowered."

Gary Jones

"I found the software extremely user friendly and extremely efficient unlike using HMRC software which has calculation errors. Also the service is not too expensive so this great."

Janet

"Really clear presentation of what I had to fill in for my Self Assessment as a foreign resident with UK pension and rental income. System stayed open and didn’t log me out while I took my time assembling the necessary information."

Mr. Michaelides

"Such a simple and simplified process. Took all my concerns away. Very well constructed website and plenty of all necessary information easy to access."

Richard Windsor

"Great software and so easy to use. Would thoroughly recommend. Support staff are available if needed and are very helpful."

SG

"For nearly 30 years I’ve had an accountant to fill in the Self Assessment form. Both of us have now retired and I was dreading having to deal with the HMRC forms and paperwork myself. But the GoSimpleTax online system is extremely well structured, supportive, understandable and helpful at each stage, leading you through the different sections you need to fill in."
