Lou Card, although your question is very straightforward, the answer isn't as simple as the tax brackets of 10 and 15 percent. There's more to it than that.

For instance, what about the deductions and exemptions you are allowed to take to get you to your taxable income for that bracket. This matters regardless of whether or not you stay in the same tax bracket. Does that make sense? That is where many of the changes are coming for everyone, regardless of your gross income.
