## What does the calculator picker do?

The picker turns a plain question into a short list of calculators. It does not ask for your income or any personal details. You press one topic, such as "The income tax I owe, or my refund", and it shows the calculators for that topic. Press another topic to see a different list.

## Which questions does it send you to?

The picker routes each topic to calculators on this site. These are the main routes.
