You owe tax on a 401(k) or IRA distribution for the tax year in which the money was paid out, even if you don't cash the check until the following year.

The plan sponsor must file a Form 1099-R, reporting the distribution and any withholding, in the same year the money is distributed.

The IRS most likely received enough questions on the timing to issue such a broad rule, Slott says. Some businesses hold on to checks received for services until a subsequent calendar year and record the money as income then, and individual taxpayers may have assumed the same practice was allowable for retirement plan distribution checks.

One way to avoid the issue altogether: Consider using direct deposit if your custodian offers it. That could eliminate any potential problems, Slott says, because the check would be deemed immediately cashed. But plans aren’t required to offer a direct deposit option and some plans will only process distributions by check, says Jeffrey Levine, chief executive officer of BluePrint Wealth Alliance, in Garden City, N.Y.
