1) It has to be available to rent for you to claim the deductions.
2) If you have no other income, $100k rent, $120K deductions, you pay no tax. You only pay tax if the income EXCEEDS the expenses.
3) The ATO will not allow you to claim interest unless the asset you have purchased with borrowed funds is income producing. You can not claim interest as a deduction for a capital, non-income producing asset. (like diamonds, as per your earlier example)
1. It has to be available for rent, but you certainly are allowed to have it vacant if you cannot find suitable tenants. What ATO emphases is that you cannot use it for private purposes. It has be available for its business purpose of renting out and making money. If your tenants don't pay the rent or you can't find the right tenants, you can still fully deduct the expenses.
2. A clarification; if you make a negative income, it is assessed for tax, but no tax is payable as there is no tax for income below $0. Further, if you have a positive income but still under $6000, it is still assessed for tax, but no tax is payable. If the income is above $6,000, it assessed for tax and there is a tax to pay. So, what matters here is whatever the income you make is assessed for tax. Anything below is $6000 is exempted from paying tax, but still assessed.
3. I didn't know this. I highly doubt what you say is correct. Suppose I invest in non income producing assets like Diamonds. The underlying principle of negative gearing is that if "business income" is taxable, then the "business expenses" must be exempted from tax. As far as I understand, this is the underlying principle that applies to individuals and companies.
So, whether I invest in houses or diamonds or antiques, business expenses (of holding on to the assets while servicing the loans) should be tax deductible. If buy diamonds for $500K on a interest only loan, my understanding is that all the interest is deductible as the interest is the business expense of maintaining the asset.
Now, I am saying this from my basic understanding of tax concepts. I could be WRONG and ATO may be not allowing the deduction of business expenses of non income producing assets. I did a quick search on google, but could not find any specific regulations on non-income producing assets. I will do more searching on this. Thanks for pointing out.
You don't understand how the tax system works. Let's say the government didn't allow negative gearing. Your wage is $80k, your rent is $15k and your expenses are $20k.
What is your taxable income? $80K. Same as it was BEFORE any rent or expenses.
Because we have negative gearing, you can offset your rental LOSS against your other income. So you only pay tax on $75k.
That's $80k wages, less the rental loss of $5k. No tas is paid on the $15k income. None, nada, zip.
Look at this way.
Wages - $80K.
IP Expenses - $20K.
Rental - $0
Your house is available for rent, but you could not find a suitable tenant
Or you have tenant, but he did not pay the rent.
These are valid cases.
So your taxable income is $80K - $20K + $0 (rent) = $60K.
Next year, you earn $10K in rent.
So your taxable income is $80K - $20K + $10K (rent) = $70K. Taxable income increased by $10K, which is the rent.
Next year, you earn $12K in rent.
So your taxable income is $80K - $20K + $12K (rent) = $72K. Taxable income increased by $12K, which is the rent.
Next year, again you can't find a tenant.
So your taxable income is $80K - $20K + $0 (rent) = $60K. Taxable income decreased by $12K, which was the rent.
So, the bottom line is, every dollar you earned from the rental income is assessed for tax and you pay tax on every rental dollar depending on the tax bracket you are.
