The History of partnership

APARI & SERAPION

Apari Logo
Serapion Logo Icon Only
Apari and Serapion started collaborating in 2020 with the idea to digitalize tax preparation, submission and compliance, particularly for UK Self Assessment (SA) and Making Tax Digital (MTD) requirements.
Following HMRC’s decision to roll out Making Tax Digital across all traders, demand for reliable digital tax solutions increased significantly. Serapion and Apari were able to respond to this demand and the first version of the product was launched in 2021.

Over time, the collaboration between Serapion and Apari evolved into a large, cross-functional team that took ownership of the platform’s core components as well as supporting its infrastructure, enabling continuous scalability and adapting to changing regulatory requirements.
The Vision

The Vision

WHERE IT ALL BEGINS

Apari wants to take the stress out of taxes by empowering individuals, self-employed professionals, landlords, and accountants to handle tax preparation and submission confidently and efficiently.

The goal is to replace confusion and paperwork with clarity and guidance, so users always know what to do next. Apari makes the process simple, accurate, and even a little bit easier, thanks to AI that supports users behind the scenes without getting in the way. Ultimately, it’s about helping people spend less time worrying about taxes and more time focusing on what matters to them.
