Hi, I will do my best to address your concern. Did you do cleaning for private persons or for businesses?
I assume that was not regular jobs, but self-employed activities. If you worked for businesses - you shoudl receive a reporting form 1099-misc if they paid you at least $600. You need to use schedule C - http://www.irs.gov/pub/irs-pdf/f1040sc.pdf to report all your income on the line 1 . You wil also report your related expenses - please see lines 8-27 for the list of expenses.
You will calculate your gross income from your cleaning activity on the line 7.
That amount will be included into your income and reported on the tax return line 12 - http://www.irs.gov/pub/irs-pdf/f1040.pdf
In additional - if your gross income is more than $400 - it might be a subject of self-employment taxes. Please use the schedule SE to calculate your self-employment taxes - http://www.irs.gov/pub/irs-pdf/f1040se.pdf - generally - it would be 15.3% of your gross business income. Half of your self-employment taxes will be used as a credit on the form 1040 line 27, and total amount will be added to your tax liability - line 56.
and Earned Income Credit - line 64a
Let me know if you ned any help or clarification. I will do my best to make these things clear for you.
Sorry - I just noticed that you are asking about Australia taxes, not US taxes...
I will opt out - so other experts may better serve you. Sorry for confusion.
ok no worries
