As the end of the year approaches, it's time to consider strategies that could help you reduce your tax bill. But most tax tips, suggestions, and strategies are of little practical help without a good understanding of your current tax situation. This is particularly true for year-end planning. You can't know where to go next if you don't know where you are now.

So take a break from the usual fall chores and pull out last year's tax return, along with your current pay stubs and account statements. Doing a few quick projections will help you estimate your present tax situation and identify any glaring issues you'll need to address while there's still time.
