This form may be used to request an extension of time to file information returns submitted on paper to the IRS.

- is submitted on Form 8809,
- provide detailed explanation as to why the additional time is needed, and

Federal Income Tax Withholding Applicable to Solo 401k or Individual 401k
Since Solo 401k or Solo k distributions are for the most part includible in the taxable income of the participant/trustee, the withholding for federal income taxes applicable to distributions is the responsibility of the Solo 401k or Individual 401ktrustee. Consider the following two primary items when determining the proper amount to be withheld from the Solo 401k distribution: 1) the type of distribution the participant/trustee is receiving and 2) whether any part of the distribution includes after-tax contribution amounts or Roth Solo 401k contributions.
Who is Responsible for the Tax Withholding on Solo 401k or Individual 401k Distributions?
