Double Check Before You Accept This Can't-Miss Offer


Rewards cards such as Capital One's (NYS: COF) Venture Card have their advantages. Sign up and you'll enjoy up-front bonuses and generous mileage payouts to spend on free travel. There's just one problem: "free" might not be free much longer.

Last week, L.A. Times columnist David Lazarus reported that Citigroup (NYS: C) is sending tax statements to customers who received miles for signing up for a checking or savings account. Each mile is worth $0.025 in taxable income, Citi says. But they're wrong.

Why miles shouldn't be taxable
Before I get into why, let's talk about what's actually happening. Citi is sending statements to the Internal Revenue Service that show income, just as all banks send the IRS 1099 statements reporting interest income during the year. Brokerages send in similar forms reporting dividend income.

A copy of every year-end tax statement you have is sent to the feds. Fail to report the numbers within, and your chances of audit rise. Thus, in kicking off statements, Citi has put customers who were expecting free miles to be, well, free in a compromising position. Report the (ahem) "income" or risk an unwanted visit from Uncle Sam.

For its part, Citi told Lazarus that any prize or award that exceeds $600 must be reported to the IRS as taxable income per the 2012 instructions for IRS F orm 1099-MISC. The feds wouldn't clarify for him whether Citi was right or wrong in its interpretation.

The math of mileage
I've never been and won't ever be a tax agent, so I can't speak to the issue of taxability, but I do know that Citi's math is Washingtonian in its fuzziness. No airline program gets within spitting distance of offering $0.025 a mile worth of value to its members.

Travel hacking site Nerd Wallet did the math and found that Continental's OnePass offered the most at $0.0101 a mile of value. But that was before the merger that created United Continental (NYS: UAL) . We're only now seeing the effects of a combined program, but it's possible that the carrier's new Mileage Plus will offer not much more than the $0.0083 a mile in value it has historically.

Or consider the Venture Card. Capital One's terms and conditions say the company will reimburse $100 of airfare for every 10,000 miles spent, or $0.01 a mile. American Express (NYS: AXP) allows its Membership Rewards customers to exchange 15,000 points for a $150 gift card, also $0.01 per point.

Most consider roughly $0.01 a mile the industry standard when valuing frequent flier miles. In Citi's case, opening an account qualified some for up to 23,500 American AAdvantage miles.

Nerd Wallet estimates the per-mile value of bankrupt American's program at $0.0076. But even if you call it the industry standard of $0.01, Citi isn't just sticking customers with a tax bill they didn't expect -- the bank is also grossly overstating mileage income, and therefore the resulting tax liability.

The other math of mileage
Even so, it's hard to blame Citi for overstating the value of miles. Banks make so much from offering them. Again, consider the Venture Card. Capital One dishes out two miles for every $1 spent. With interchange fee income, interest charges, and other fees that result from that extra spending, paying what amounts to $0.02 per dollar is a bargain. This, Fool, is a big part of why Capital One's U.S. credit card business enjoyed 46.5% pre-tax margins last year.

Citi doesn't do quite as well with a 31.5% pre-tax margin in its consumer banking segment, while American Express trails the pack at 28.7%. Yet I think it's fair to say maintaining those levels would be much harder without virtually free inducements such as miles to draw in potential customers.

United Continental and its peers enjoy a similar benefit. Mileage is a huge profit driver for how it draws in loyal flyers who tend to pay higher overall fares for business travel. Some even buy miles directly at what amount to outrageous rates. As of this writing, 2,000 miles that buy roughly $20 worth of redemption value will cost you $75.25. For carriers like banks, miles are a margin-maker.

What If the IRS acts?
Lazarus didn't get much when he asked the IRS to rule on Citi's decision, which leads me to believe that other issuers won't follow its lead. But if they do -- or if the feds decide that miles are income -- then it'll gut the value of rewards credit cards. Or at the very least, it might entice some travel hackers to gather up less than the $600 value limit across varying programs and then combine miles via trading portals such as You can bet banks are hoping it doesn't come to that; sustained use increases the odds of collecting interest and boosting profits.

In the meantime, I'd strongly advise against signing up for any Citi-sponsored program that offers miles as an enticement. Also, be sure to read the terms and conditions before accepting any rewards card offer. What seems like a no-brainer could trap you with fees or payments you hadn't banked on.
