        pursuant to section 6213(b) of the Internal Revenue Code of

[[Page 139 STAT. 661]]

        1986 by certified or registered mail with e-signature

            (2) report to Congress, aggregated by the type of error 
        under section 6213(g) of such Code to which the notices relate,

                response and adjustments or abatements to tax,
