WASHINGTON (AP) — A last-ditch tax deal in the Senate might let the U.S. economy escape the worst of the so-called fiscal cliff and avoid going back into recession. But even if the House goes along, the tax increases likely coming in 2013 will dent economic growth anyway.

In the early hours of the new year, the Senate voted to end a long stalemate and raise taxes on upper-income households, extend long-term unemployment benefits and postpone decisions over government spending cuts, officials said. But any deal needs approval from the House.

About $536 billion in 2013 tax increases were scheduled to take effect Jan. 1, along with $109 billion in cuts from military and domestic-spending programs, if Democrats and Republicans could not reach agreement.
