Give your clients a
branded tax calculator
White-label calculatetax.uk for your accounting practice. Your brand, your domain, our engine.
Why accounting firms choose us
Save client time
Clients answer their own basic salary questions before calling you. Fewer "how much tax do I pay?" calls means more time for the complex work that actually requires your expertise.
Your brand
Customised with your logo, colours, and domain. Clients see your practice name — not ours. A professional calculator strengthens trust and positions your firm as forward-thinking.
Always up to date
We maintain the tax rates each April when HMRC publishes new figures. You never need to touch it. Clients always get the current 2025-26 calculations — automatically.
How it works
