What it does
The calculators run on the same engine and the same published HMRC rates as the calculators on goforma.com, so an answer in your assistant matches the one on our website. Results are estimates for the tax year stated, not tax advice.

Things to ask
- I am a contractor on £550 a day. How much would I take home through a limited company compared with sole trader?
- My company made £68,000 profit this year. What Corporation Tax will it pay?
- I sold some shares in August with a £14,000 gain and earn £45,000. What CGT do I owe?
- I drove 12,400 business miles this tax year. What can I claim?
- What would GoForma charge for a single-director limited company that is not VAT registered?
Limits
- Figures are estimates based on published HMRC rates and the inputs given. Other income, allowances, residency and tax codes change the result. Speak to an accountant before acting on one.
- Rates cover the tax years each tool lists. We update them when HMRC publishes new ones.
- The connector does not see your accounts, your GoForma account if you have one, or anything in your conversation other than the values your assistant passes to a tool.
request_consultationis the only tool that sends anything to GoForma. It needs your name, email and question, and your assistant asks you to confirm before it runs.
