Will I receive a tax form due to the 401(k) distribution I took out this year?

If you received a distribution from a 401(k)pension plan, annuity or insurance contract, the company that makes the payment will send you a Form 1099-R. This form is also sent by organizations that distribute payments from a profit-sharing plan, Individual Retirement Accounts (IRAs), or other retirement programs. The IRS will also get the same copy.
