Unfortunately, the distribution cannot be rolled back into the IRA because the 60-day rollover period has passed; it is a taxable distribution. The rollover deadline can be waived for certain situations that are beyond a taxpayer’s control that prevented completion of an intended rollover, such as a serious illness, a mistake by the financial institution, or a casualty event. However, because the funds were used as a loan, the IRS won’t grant an extension (see, for example, Letter Ruling 200446030).
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.
