You may need to request a withdrawal through your employer or by calling Fidelity directly. Check with your benefits department, or call your plan's toll-free retirement benefits line for more details.
Some plans also allow hardship withdrawals for other reasons.
Check with your benefits department. You will need to show your employer proof of how you intend to use the money, and proof that the amount you requested isn't more than enough to satisfy your need. The withdrawal will, however, be subject to 10 percent mandatory withholding unless you elect out of withholding. In a nutshell, you must eventually pay ordinary income tax on all money in your account that has not yet been taxed. Since you have already paid income tax on the money that you contribute to your after-tax account, you do not pay income tax on this money when you withdraw it.
