multiple self employment as performer.

I’m both a piano performer and a music teacher, at the same time an actress and do modeling work (with agent). They are all self employment jobs, but do I declare my income and expenses together? Or do I file them separately? How do I calculate acting agency fees? What expenses can I declare as a self employed online music teacher? Mortgage interest? Hydro? Electricity? Phone bill? Internet? Thank you!

Hi 

You would show them as separate sources on your tax return and declare the income and expenses that are relevant to each source.
For details on what you can claim, please refer to Expenses if you're self-employed

Thank you
