This year in particular, year end tax planning is full of uncertainties. This makes it even more difficult than previous years. If you believe that tax rates will not rise in 2011, including the 15% top rate on qualified dividends and long term capital gains, here is what most taxpayers should consider doing:

Accelerate deductions from 2011 to 2010 and defer income into early 2011 (do not jeopardize collection of the income), unless you expect to be at a higher marginal tax rate in 2011.

If you qualify to itemize deductions shift state and local income taxes into 2010. Pay your estimated tax payment s due in January, 2011 in December, 2010. This is not a strategy if you expect to be subject to the dreaded “alternative minimum tax” in 2010. Accelerate charitable contributions into 2010. If possible, make the donations using appreciated investments held more than one year. Do not donate investments that have declined in value. Pay your January, 2011 mortgage payment in December of 2010.

If you plan to do a Roth IRA conversion, converting in 2010 allows you to spread the resulting tax over 2011 and 2012. If you wait until 2011 to convert, the two year spread is not available.

Harvest capital losses, matching losses with capital gains to produce a net loss of $3,000. If you have a capital loss carry forward (from 2009 and earlier years), harvest capital gains if it fits your overall investment strategy in order to take advantage of the tax benefit.
