IRS says up to 350,000 tax rebate checks wrong

According to this article on tax rebate checks:

Up to 350,000 households aren't getting the $300 per child owed them as part of their economic stimulus rebate payments, the Internal Revenue Service said Thursday.

The tax agency says taxpayer human error and computer glitches were responsible for the problem affecting a tiny percentage of the 130 million taxpayers expected to benefit from the refunds the government began sending out last month.

IRS spokesman Terry Lemons said the agency was confident it had identified all the people affected by the mistake. He said the IRS will send letters to those who missed out on the refund and that checks for the child credit will be mailed out in July. People need not contact the IRS or file additional paperwork, he said.
