Hmm. We've pondered this here in the forums before I think. I don't know the answer either, but the prospect that a card issuer is potentially losing money per transaction doesn't feel right to me. If true it would represent a massive unknown potential for loss, even inside their narrow(ing) focus of what a legitimate transaction might be.
Given that almost all credit card providers, and certainly the EDRCC, will spank you viciously for combinations of late payment or not clearing your account monthly, it really does appear to me that they don't encourage or want customers to have rolling balances.... so what could their ultimate business model actually be? Where is the money? Why would they entice points chasers with sign up bonuses only to face a loss each time transactions are made? Or it this a very narrow case of the merchant (ATO) having enough leverage to screw the card company back, whereas there are workable and decent margins to be made elsewhere? I can't imagine Woolies not driving a hard bargain ...
It doesn't make sense to me either, but I can't find a gaping hole in my logic :-|
Regardless of the split between Optus / Visa/MC / card issuer, we know that there can't possibly be any more than 0.48c per $1 charged in direct revenue for the card issuer (and of course it
will be less than that). That measly 0.48c has to pay for whatever rewards program they're offering their customers (not to mention all their operational costs), and if it's one of the more generous FF-point-based ones I just can't see how 1+ (insert airline program here) point could cost less than 0.48 cents.
Thinking about it, I see three possibilities:
1) I'm entirely wrong and it's making them money directly on every transaction - the tiny surcharge is, in fact, enough to cover the costs of points + operational costs. Personally I feel this is unlikely due to my estimated cost of rewards, let alone operations.
2) There's a (high?) degree of cross-subsidy going on - the majority of (or at least enough) customers paying tax via any given CC are redeeming their points for "cheap" (non-airline) rewards, are earning the card issuer lots of additional revenue through interest / late fees / whatever, etc, that the card issuer is making money on these transactions
overall. And hence whilst they'd love to stop those of us who redeem for the high-cost rewards, pay our balances on time, etc, from paying tax on CC and costing them money, they can't ban / devalue it at the "card product" level or they'd cost themselves money
overall. I'd rate this as a distinct possibility - it's perhaps the most reasonable explanation in my view, although I do wonder if it really can stack up in the case of particularly high-rewards-earning (and hence costly to the card issuer) card products - which also tend to be the cards used most for paying big tax bills, at least based on the AFF audience.
3) It's costing them money in all / almost all cases - the tiny surcharge rarely (or never) covers the cost of points / rewards + operational costs, but corporate inertia / lack of realisation of this problem / not wanting to "move first" and piss off or lose customers prevents the card issuers from acting to fix it. I'd also rate this as a reasonable possibility, although it's certainly the option I "most hope" I'm wrong about as it implies eventually we'll lose this wonderful benefit.
Or it this a very narrow case of the merchant (ATO) having enough leverage to screw the card company back
I don't think it's not the ATO specifically, I think it's the government as a whole. A list of merchant categories and fee amounts that I saw recently (from one of the major banks) showed a "government" category with a 0.33% fee - that's where I got 0.33% from in my earlier post, and it makes sense given the sort of margin you might expect Optus to charge, not to mention the fact that the VIC Office of State Revenue charges exactly 0.33% surcharge for any CC payments you make with them (and they don't use an outsourced payment platform AFAICT).
