I've highlighted your problem. I'm glad you can admit that the statement is subject to interpretation.
Once again - No, I don't read the statement that way. I read it exactly as per your interpretation. The difference is how I buy that investment, which may affect the tax liability. Regardless of how I buy the investment, it still makes $10000. There are 2 issues, making pocket money for the wife and separately paying tax on that income. That is not changed by how the accounts balance out. You can keep making up these strawmen to misrepresent my point, but it just looks like clutching to me.
Actually, it is open to interpretation, you've said so yourself in the first sentence. Obviously your interpretation requires you to live and die by the final number in the accounts. My interpretation is that if I'm going to forego the earnings on 100's of thousands of dollars to make my wife happy and give her money, then I have no problem dropping in another $10000 in interest to maximise her pocket money and minimise my tax bill.
Seems like 2 widely different interpretations to me, which significantly alter the tax question posed.
Glad to see that you now agree that my unambiguous statement of "
An investment that makes $10000" means an investment that makes $10,000.
Now, how is such an investment treated for tax purposes on one's tax form?
Answer -
Add the Gross Profit to one's income in one's tax form, and
Subtract the interest expense earning that Gross profit.
So, in the case of an ungeared investment - add $10,000 and subtract 0
In the case of a a geared investment earning the $10,000 that both you and I mean, there are an infinite number of combinations e,g.
Add $15,000 Subtract $5000 = $10,000
Add $13,000 Subtract $3000 = $10,000
Add $20,000 Subtract $10,000 = $10,000
etc etc etc.
Regardless, of however you finance the geared investment, your tax will be calculated on $10,000 at your marginal rate.
