Marginal vs. effective rate — what's the difference?
Your marginal rate is the tax on your last dollar (your bracket). Your effective rate is total tax divided by taxable income — always lower, because earlier dollars fill the lower brackets first. The calculator above shows both.
Why would I need 2010 brackets now?
Filing or amending a 2010 return, negotiating back taxes for that year, checking an audit figure, or research. Brackets never change retroactively once the year closes.
