Everything free, in one place

The weekly video explainers, the calculators used in the office, and the written guides. All free, none of it gated, and no email address required for any of it.

The tools are built to preparer standard rather than to look impressive — which means they will sometimes tell you that you do not need us.

Nothing you type into a calculator is sent to us or stored anywhere. Every calculation runs in your own browser and stays there. No account, no email address, no data collection — close the tab and it is gone.

Is there a calculation you keep doing by hand?

This library grows from the questions clients actually ask. If there is a number you find yourself working out on paper every year — or a rule you can never remember the threshold for — tell us and it may well become the next tool here.

When the tool is not enough

A calculator cannot know your facts

These give you the arithmetic. What they cannot do is tell you which rule applies to your situation, or what happens when two of them interact. That part is a conversation, and the first one is free.
