This is one of the risks associated with this type of account. Another thing to know about self-managed 401 (k) accounts is that when you withdraw your money, you have to pay an additional 20% tax in addition to the taxes you would normally pay. If you make an excessive contribution to your 401 (k) plan, it is your responsibility to notify the plan administrator and request that the excess contribution be returned to you before the following year's tax deadline. Otherwise, the excess contribution doesn't reduce your taxable income and you must pay taxes when you withdraw it.
That means that the same income is taxed twice. Leaving excessive deferments in your account can also cause the IRS to disqualify your plan. Even so, if you've decided to use the self-directed 401K, there are two ways to use this service to finance the home. The self-directed 401 k plan is often overlooked because the most common retirement plans for the self-employed have traditionally been the SEP IRA and the SIMPLE IRA.
