President Obama has been reelected, the Senate will remain in the hands of the Democrats (but without a filibuster-proof supermajority) and the House will continue to be controlled by the Republicans. In other words, the political makeup of Washington will be about the same in 2013 as it is now. As a result, it’s still very uncertain what will happen with tax law changes.

When it comes to tax law, Congress and the president have much to address, including tax breaks that expired at the end of 2011 as well as the rates and breaks that are scheduled to expire at the end of this year.

The “lame duck” session is scheduled to begin next week, but Congress will soon break again for Thanksgiving. How long it will be in session from after Thanksgiving through the end of the year is up in the air.

It’s still unclear what Congress will try to accomplish in the lame duck session — and what they’ll punt to next year. (In terms of the latter, tax law changes could be made retroactive.)

The lack of change in the political makeup of Washington could make it very difficult to pass tax legislation, considering how far apart the parties are on what should be done. Yet now that both parties know the outcome of the Nov. 6 elections, they may be more willing to compromise.

Whatever happens, it could have an impact on your year end tax planning. So keep an eye on Congress before implementing year end strategies.
