The problem is the proper tax for those numbers is $126.01. I see your tax percentage is 10% (yikes!). When you multiply 14.55 * 0.10 your result is $1.455. Since the 3rd digit 5 must be rounded (up in this case), your tax on that is $1.46. Unfortunately due to rounding $126.00 is not the correct total. I would think if the tax man knocked on your door, he/she would probably want that 1 cent that you were supposed to charge.
The only thing you could possibly do is if the $14.55 is an Expense, you can use a 3rd digit. For example change the total to 14.545 and that + $100.00 would round to $126.00 after taxes, which would probably be fine even if you were audited as it would show 14.54 in the main screen (the detail/Edit screen would still show 14.545) and they would think that you overcharged by 1 cent.
