IRS Urges Double-checking Dependent Social Security Numbers

Tax season is well under way, so it makes sense that the IRS would begin warning taxpayers about common oversights. One oversight, however, comes with “an additional tax due” letter.

The problem involves dependent social security numbers. If a dependent’s social security number doesn’t match the tax return, the IRS will recalculate the tax return as if the dependent did not exist. This automatic “redo” can cause problems for taxpayers and accounting firms when the notices start showing up.

One scenario affected a taxpayer who filed as head of household when her child’s social security number contained two transposed numbers. The taxpayer not only didn’t qualify for head of household, but the dependent exemption was revoked as well. The notice received by the taxpayer claimed $2,500 of additional taxes were owed.

It’s easy to fix the situation if an error occurs. The accounting firm or taxpayer simply has to respond to the notice. However, it’s much easier to double-check the numbers before they hit the mail. It will save time and client relations in the process.
