About wastudio.tech
wastudio.tech is a technology studio that builds simulators for complex tax and payroll systems. This UK edition applies the same platform to England, Wales and Northern Ireland bands (Scotland flagged where rules diverge).
Why wastudio.tech instead of a narrow product domain?
A name like uk-tax-calculator.co.uk would describe one page. We are a studio that designs calculation products — the fiscal simulator is our first large public release, shared with other country editions under one technical brand.
wastudio + .tech signals engineering and product craft; it does not lock us to a single HMRC topic or locale.
What we do
We publish calculators and explainers so you can brief accountants on PAYE vs. self-employment vs. company extraction. IR35 and off-payroll working rules are described in articles but not auto-scored here.
