FACTBOX-Legislation pending in returning U.S. Congress

WASHINGTON, Sept 9 (Reuters) - Here is some of the

unfinished work that awaits the U.S. Congress when it returns on

Monday after a five-week recess:

SPENDING BILL

Perhaps the only measure that will receives final

congressional approval between now and the Nov. 6 election will

be the one to keep the government up and running into the new

fiscal year, which begins on Oct. 1.

TAX AND SPENDING CUTS

Lawmakers face a wave of decisions on tax and spending

issues to avoid what has been dubbed a "fiscal cliff" at the end

of the year. If Congress fails to act, tax rates will rise and

massive spending cuts will go into effect.

DEBT CEILING

Treasury Secretary Tim Geithner has said that the United

States will likely hit its $16.4 trillion borrowing limit after

the election but before year's end. He has said that the

Treasury has tools to push out that deadline into early 2013.

TAX EXTENDERS

Dozens of tax breaks expired at the end of 2011, including a

research and development tax credit for businesses and one that

lets financial institutions defer taxes on some profit. Many

congressional observers believe Congress will renew many of the

breaks, known as "tax extenders," in a post-election session.

PAYROLL TAX

A cut in the payroll tax that funds the Social Security

pension program was extended earlier this year with the aim of

boosting consumer spending. The current 4.2 percent tax rate

paid by about 160 million workers is down from a previous 6.2

percent rate and expires on Dec. 31. It is unclear whether the

tax break for workers will be extended as part of any

end-of-year deal.

FARM BILL

Pressure is building to pass a farm bill to replace a 2008

law that expires on Sept. 30. If there is no action, lawmakers

will likely extend the current law and take a run at the bill in

the post-election session.

The House and Senate disagree on how far to go in

redesigning farm subsidies and how much to cut in food stamps

for the poor. The House Agriculture Committee has proposed the

biggest cuts in food stamps in a generation, $16 billion.

POSTAL REFORM

After more than a year of haggling, lawmakers are still

seeking a deal to revamp the cash-strapped U.S. Postal Service.

The Senate passed a bill that would end Saturday mail

delivery, allow the agency to use surplus funds in a retirement

account and reduce the amount the Postal Service must set aside

for retiree health benefits.

But House leaders complain that the bill would postpone the

mail agency's problems, not fix them. Rural lawmakers criticize

the House measure, which would create oversight groups to close

postal facilities and cut costs.

FED AUDIT

Senate Democrats say they are confident they can defeat a

House-passed bill that would subject the Federal Reserve's

monetary policy decisions to a congressional audit. Critics

charge that the bill would jeopardize the Fed's independence.

VIOLENCE AGAINST WOMEN

Democrats charge that a House-passed bill to renew the 1994

Violence Against Women Act would undermine the existing law and

inadequately protect gays, illegal immigrants and Native

Americans. Republicans accuse Democrats of being more interested

in playing politics than enacting meaningful legislation.

RUSSIAN TRADE

Congress is under pressure to approve "permanent normal

trade relations" with Russia to ensure U.S. companies share in

the full market-opening benefit of Moscow's recent entry into

the World Trade Organization.

U.S. firms fear they will be left at a disadvantage unless

Congress takes the action. But Russia's support for Iran and

Syria may undermine the effort.
