What this page does not tell you

This is one threshold, read from the source linked above. It is not advice, it does not say what you owe, and it does not cover every rule that might apply to your work — registration can be required for reasons that have nothing to do with a dollar figure. Check the source, and talk to an accountant about your own situation.
