(3) Excess contributions returned before due date of return (A) In general If any excess contribution is contributed for a taxable year to any health savings account of an individual, paragraph (2) shall not apply to distributions from the health savings accounts of such individual (to the extent such distributions do not exceed the aggregate excess contributions to all such accounts of such individual for such year) if— (i) such distribution is received by the individual on or before the last day prescribed by law (including extensions of time) for filing such individual’s return for such taxable year, and (ii) such distribution is accompanied by the amount of net income attributable to such excess contribution. Any net income described in clause (ii) shall be included in the gross income of the individual for the taxable year in which it is received. (B) Excess contribution For purposes of subparagraph (A), the term “excess contribution” means any contribution (other than a rollover contribution described in paragraph (5) or section 220(f)(5) ) which is neither excludable from gross income under section 106(d) nor deductible under this section.
