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 ruling makes it clear that you can’t hold off on paying taxes by taking a distribution at the end of the year, then holding on to the check and cashing it in January or beyond of the following year, says IRA expert Ed Slott. “Even though you may think you can defer until another year, it’s still taxable for the year it came out of your plan,” he says. 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.
