If you simply round to the nearest penny (3,4,5,6,7=5, and 8,9,0,1,2=0)on all transactions, then it evens out.

Those pennies really don't add up. See if you can find a store that won't add in the extra pennies to round you up, seriously - they certainly don't care.

A lot of fraud has been perpetuated by people shaving fractions of pennies off payrolls etc. Of course it adds up, and nobody's going to be rounding down anything. If a product costs 1.37, you will pay 1.37 with a credit card, and 1.40 with cash. And yeah it's the blue collar slob with two bankruptcies whose going to get his pennies shaved off.

No you won't. I never see charges with fractions of pennies when I use my card at the gas pumps (which charge 9/10¢ extra per gallon, remember); why would I see charges with fractions of nickels when pennies are gone?

I'm pretty sure the IRS cares though. GAAP don't allow you to just adjust numbers.

The IRS generally allows rounding to the nearest dollar on tax forms (at least individual and small business; not sure if large corporate are allowed to round even more). In fact, all the common tax software does so automatically; the only way to file a return to the cent is to do so by hand.

[colanderman]

I'm pretty sure they don't, or else they'd be hounding you for the fractional pennies that you owe them (3/20 of every penny earned, remember!).

I doubt they care, as long as you pay 10% (or whatever it is) of total taxable revenue. I think that's how it works in Australia, where we do round.

The tax man only cares about aggregates, unless they are in audit mode.
