Terms
What this site is, and what it isn't.
It's an estimate, not advice
The figures this tool produces are illustrative. They are not tax advice, financial advice, legal advice, or a forecast, and they should not be used to make a filing decision or a financial commitment. Talk to a qualified professional about your own situation.
Accuracy
The model is built on published analyses and projections, and on the assumptions listed on the method page. Those assumptions can be wrong, and policy can change at any time. No guarantee is given that any figure is accurate or complete.
Independence
This site is independent. It is not affiliated with, endorsed by, or funded by any government body, political party, campaign or advocacy organisation.
Use of the site
You're welcome to read, link to and share this site. You may quote short extracts with credit. Reproducing it wholesale, reselling it, or presenting it as your own is not permitted.
No liability
The site is provided as is. To the extent the law allows, no responsibility is accepted for any loss arising from reliance on anything published here.
