If you are among the millions of taxpayers delaying the inevitable, the Internal Revenue Service is offering a little extra help to get you through the final weekend of the tax filing season.

The agency is making many of its employees available extra hours on Saturday and Monday - the filing deadline - to answer calls on its toll-free telephone lines. The lines will be open five hours on Saturday and an extra two hours, until 7 p.m., on Monday.In addition, IRS offices nationwide that offer assistance to taxpayers who walk in will not close Monday night until the last customer has been served.

The IRS is expecting more than 25 million returns - out of the 109 million due this year - to be filed during the 16 days ending Monday night, and the agency is cautioning procrastinators against careless errors.
