Taxes on Withdrawals
A portion of your withdrawal may be non-taxable if it consists of traditional after-tax contributions. The remaining portion of your withdrawal is taxable (including any investment earnings on traditional after-tax contributions included in the withdrawal).
If your distribution includes traditional after-tax contributions made before 1987, they are deemed to be returned before any earnings. Otherwise, any distribution of traditional after-tax contributions will be deemed to include a proportionate share of any taxable earnings.
You may delay paying taxes by electing to roll over an in-service withdrawal to another employer's plan or IRA (financial hardship withdrawal distributions may not be rolled over). If you do not elect a direct rollover of your eligible amounts, the taxable portion is subject to 20% mandatory Federal income tax withholding. Also, the taxable portion may be subject to an additional 10% Federal early withdrawal tax if you have not reached age 59-1/2. If applicable, state taxes will be withheld. Consult with a tax professional to find out exactly what taxes you have to pay.
