Testimonials
We have been working with the Ziliant Tax R&D team for the past 4 years. Each year they have expertly guided us through the current schemes available to us, policy changes from previous years and most recently they have guided us through the Patent Box scheme.
Terry and Amalia have been brilliant to work with, taking the time to understand the technology, manage the sensitivity around some of the technology and provide a comprehensive narrative alongside the detailed accountancy. We know we are in good hands to make sure that our claim is accurate and optimised
- Far Field Exploits
We have worked with the R&D tax team at Ziliant Tax for many years now, and I can honestly say that their service has been nothing short of exceptional. Having previously worked with another R&D tax reclaim company, the service provided by Ziliant Tax proved to be above and beyond our previous experience, based on the time they spent to get to know our business and maximise our claim value. The R&D tax credits received from our collaboration have helped us to further drive forward our innovation as a company, helping us to achieve success in grant funding from Innovate UK, and drive us towards being market leaders in what we do.
- Lyan Packaging
We couldn’t be more grateful to Terry and Hanna for their outstanding support throughout our R&D tax claim and tribunal case against HMRC. Their expertise, professionalism, and unwavering positivity made a stressful process so much smoother. Thanks to their hard work, we not only made a successful claim but also won our case. Highly recommend them to anyone navigating the complexities of R&D tax.
- BodyMe
We confidently recommend the Ziliant Tax R& D team.
They simplify the complexities of the R&D claims process, are incredibly knowledgeable/professional and fun to deal with.
They appealed HMRC’s challenge on our claims which was then overturned which was an incredibly lengthy process with Ziliant giving reassurance all the way that they would succeed.
- Wheelwright
Amalia and the team are excellent with clear ability to draft accurate R&D and other reports at speed, including great attention to detail. The team is highly qualified, very responsive and personable; and we have worked well with them. This has resulted in SOLASTA Bio successfully securing the planned R&D tax credits.
