IRS says up to 350,000 didn't get child credit

WASHINGTON -- The Internal Revenue Service says up to 350,000 households didn't get their $300 per child refund that should have been part of their economic stimulus rebate checks.

The tax agency says human error and computer glitches were responsible for the problem affecting a tiny percentage of the 130 million taxpayers expected to benefit from the paybacks.

The agency plans to mail out checks in July to those who missed out on the child refund.
