IRA contributions in excess of the limit are subject to a 6% excise tax, unless the excess amount is removed by the deadline along with any net income attributable (NIA). The deadline for removing excess contributions is the individual’s tax-filing deadline, including tax filing extensions. For individuals who file their tax return on time, or file for an extension on time, an automatic 6-month extension applies.
