Last year my son had $6,467 of income and paid $212 in tax. This year he will, unexpectedly, have income of $200,000. He did not make 1Q estimated tax payment. Can I avoid penalties next year by making a $250 estimated tax payment for 2Q? If not, what should I do? If I did nothing, would the penalty be on the tax on $200,000, or on the tax on $6,467, or something else. Thanks.
