Thanks. That document also links to
IT 2582 - INCOME TAX : DEDUCTIBILITY OF INTEREST INCURRED ON MONEYS BORROWED TO PAY INCOME TAX (As at 18 April 1990), which explicitly states companies can claim interest expenses incurred as a result of paying income tax liabilities as a tax deduction.
That being said, both of the above documents specifically pertain to
interest, not the CC surcharge (CPF in ATO lingo). Is it a safe assumption that the ATO applies the same rules to both? I would think
yes, but this goes against the statements made on
Credit card payment fee deductibility guidelines (CPF only deductible if you didn't borrow money to pay the income tax bill), assuming sertfy's interpretation of "you" is correct.
I can see no logical difference when it comes to deductibility between (1) interest paid on a borrowing to pay tax and (2) CC fees incurred when you use a CC to pay tax. Both are a cost of obtaining funds to satisfy a tax bill and if the first is deductible to companies and sole traders then so should the second.
The credit card deductibility guidelines you refer to appear to be a potted (and somewhat poor) attempt to summarise three Interpretative Decisions issued by the ATO:
ATO ID 2010/159 - Deductibility of card payment fee incurred in paying income tax liability under section 8-1 of the ITAA 1997
ATO ID 2010/160 - Deductibility of card payment fee incurred in paying income tax liability under section 25-5 of the ITAA 1997
ATO ID 2010/161 - Deductibility of card payment fee incurred in paying income tax liability under section 25-25 of the ITAA 1997
These deal respectively with the question whether the CC fee is deductible to
an ordinary wage and salary earner under three provisions, s8-1 (general deduction for costs of earning income), s25-5 (cost of managing tax affairs) and s25-25 (expenditure incurred in borrowing money to produce income).
In short the ATO says an ordinary wage and salary earner is not entitled to a deduction under any of these provisions but for different reasons:
8-1 and 25-25: because the CC fee is not a cost incurred by a wage and salary earner in earning their income, this is because the payment of tax is something that occurs after that income earning process is finished
25-5: because there is a specific exemption in this section for expenditure incurred in borrowing money including interest
It's these IDs that are summarised in the credit card guidelines and which have given rise to the view that wage and salary earners can get a deduction under 25-5 provided that they do not borrow to do it i.e. by making the payment out of a CC that is in credit. However, these three IDs issued by the ATO are expressly limited to wage and salary earners. The ATO has said nothing about the circumstances in which either sole traders or companies might get a deduction for a CC fee.
Further, the reasoning used in these IDs to deny a deduction under s8-1 is reasoning that does not apply to sole traders and companies because as set out in the rulings about deductibility of interest on borrowings under 8-1 I linked to above (in particular IT 2582) the payment of tax IS considered to be part of the income earning processes of those entities, as that ruling states:
"...it is considered that the interest incurred on those borrowings is a normal incident of conducting that business. That is, such an expense is an expense incurred in carrying on that business and hence qualifies for deduction under [what was the former version of s8-1]
"
Contrast this with the reason given by the ATO why 8-1 does not apply to wage and salary earners in ID 159/2010:
A careful analysis of the character of the fee indicates that it is not an expense incurred in earning the taxpayer's assessable income - salary or wages. It is a payment out of income after it has been earned.
Given that the ATO recognises this distinction I cannot see any reason why the same reasoning used in IT 2582 and 2006/269 would not apply to CC fee deductions. This is why I believe sole traders and companies should be entitled to a deduction for the CC fee under s8-1 and thus do not need to worry about making the payment out of a CC that is in credit.
(the above is subject to all the usual disclaimers etc)
PS: When it comes to companies to get a deduction for the CC fee the CC used will have to be the company's card. If you use your personal card to pay the company's tax bill then it's very difficult to see how the CC fee charged to you could be deductible to you because its not a cost of you earning your income.
