Only a taxpayer, or a representative with a taxpayer’s permission, can obtain copies of previously filed tax returns. Ask your parents to take action:
Note: If you are at least 18 years old, your parents can give you power of attorney in tax matters and then you can request the return on their behalf. They’ll have to sign IRS Form 2848 and specify the year for which your authority applies.
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.
