Can I take a tax deduction for my 401k Contribution on my tax return?

You can't take a tax deduction on your tax return for your 401k contribution because it has not been included in your taxable income. Your 401k contribution is not included as taxable income on your Form W-2 so you don't pay tax on it on your tax return.
