7% raise is pretty good ... don't expect a lots of raise for 2007-2008 .. 2006-2007 is a good year .. most people had good salary raised .. but coming yr .. expect a min raise la..
One should always know the average tax is different from "marginal tax rate"
"Marginal tax rate" is what tax rate one will pay for each additional $ of income earned. If your marginal tax rate before the raise was 28% and your raise put one in a top 43.5% rate, only the additional amount is subject to 43.5% -not the earnings before.
Bottomline - earn as much as possible and don't worry about the tax (for now) - thats how the wealthy people earn their money
Exception- If your income is very high this year and you may be laid off very soon - then the final pay/severence pay
may be better off if paid in the next tax year where your income may be less than the current year
