Just wondering, if I was to turnover 74k per year as a small business/sole trader,
and I buy a residential unit and rent it out to help pay the mortgage.
will the rent count towards my income putting me over the limit and requiring me to register for gst.?
As mentioned already depends on the rental per year, Rental Income minus Expenses = Taxable Income.
what is the relationship to GST?
According to the ATO if your annual business income is less than $75000 you don't have to register for GST. Rental income pay put you over this threshold since you're already earning $74000.
No it won't put you over the threshold as residential rent is outside of the GST regime.
as above, residential rent is outside gst regime. if positively geared its more likely to impede on your taxable income.
Depends if the rent is greater than the mortgage repayments. You only pay tax on the gains if it is positively geared. You really should be getting an accountant to give you advise as they would be able to see the full picture, there is so many other variables other than what you provided.
