26 U.S. Code § 1400S - Additional tax relief provisions
Except as otherwise provided in paragraph (2), section 170(b) shall not apply to qualified contributions and such contributions shall not be taken into account for purposes of applying subsections (b) and (d) of section 170 to other contributions.
Any qualified contribution shall be allowed only to the extent that the aggregate of such contributions does not exceed the excess of the taxpayer’s contribution base (as defined in subparagraph (G) of section 170(b)(1)) over the amount of all other charitable contributions allowed under section 170(b)(1).
If the aggregate amount of qualified contributions made in the contribution year (within the meaning of section 170(d)(1)) exceeds the limitation of clause (i), such excess shall be added to the excess described in the portion of subparagraph (A) of such section which precedes clause (i) thereof for purposes of applying such section.
Any qualified contribution shall be allowed only to the extent that the aggregate of such contributions does not exceed the excess of the taxpayer’s taxable income (as determined under paragraph (2) of section 170(b)) over the amount of all other charitable contributions allowed under such paragraph.
So much of any deduction allowed under section 170 as does not exceed the qualified contributions paid during the taxable year shall not be treated as an itemized deduction for purposes of section 68.
Such term shall not include a contribution if the contribution is for establishment of a new, or maintenance in an existing, segregated fund or account with respect to which the donor (or any person appointed or designated by such donor) has, or reasonably expects to have, advisory privileges with respect to distributions or investments by reason of the donor’s status as a donor.
In the case of any taxpayer determined by the Secretary to be affected by the Presidentially declared disaster relating to Hurricane Katrina, Hurricane Rita, or Hurricane Wilma, any relief provided by the Secretary under section 7508A shall be for a period ending not earlier than February 28, 2006.
The term “qualified individual” means any qualified Hurricane Katrina individual, any qualified Hurricane Rita individual, and any qualified Hurricane Wilma individual.
For purposes of this subsection, the term “earned income” has the meaning given such term under section 32(c).
Any election made under paragraph (1) shall apply with respect to both sections 24(d) and section 32.
For purposes of section 6213, an incorrect use on a return of earned income pursuant to paragraph (1) shall be treated as a mathematical or clerical error.
With respect to taxable years beginning in 2005 or 2006, the Secretary may make such adjustments in the application of the internal revenue laws as may be necessary to ensure that taxpayers do not lose any deduction or credit or experience a change of filing status by reason of temporary relocations by reason of Hurricane Katrina, Hurricane Rita, or Hurricane Wilma. Any adjustments made under the preceding sentence shall ensure that an individual is not taken into account by more than one taxpayer with respect to the same tax benefit.
