Nothing bars you from taking a distribution from your IRA and then giving the money to your granddaughter. However, if you’re withdrawing the funds from a traditional IRA (and you never made nondeductible contributions to it), you’re going to be fully taxed on the distribution. However, even if you’re under age 59½, you aren’t subject to a 10% early distribution penalty as long as your granddaughter uses the funds for qualified higher education expenses.
Advance payment of current tax liability based either on wage withholdings or installment payments of your estimated tax liability. To avoid penalties, you generally must pay to the IRS either 90% of your final tax liability, or either 100% or 110% of the prior year’s tax liability, depending on your adjusted gross income.
