As used in this article:
In addition to other applicable limitations, and notwithstanding any other provision to the contrary, for plan years beginning on or after July 1, 2002, the annual gross salary of each "Noneligible Member" taken into account under the System shall not exceed the Economic Growth and Tax Relief Reconciliation Act of 2001 ("EGTRRA") annual salary limit. The EGTRRA annual salary limit is Two Hundred Thousand Dollars ($200,000.00), as adjusted by the Commissioner for increases in the cost of living in accordance with Section 401(a)(17)(B) of the Internal Revenue Code of 1986, as amended. The annual salary limit in effect for a calendar year applies to any period, not exceeding twelve (12) months, over which salary is determined ("determination period") beginning in such calendar year. If a determination period consists of fewer than twelve (12) months, the EGTRRA salary limit will be multiplied by a fraction, the numerator of which is the number of months in the determination period, and the denominator of which is twelve (12). For purposes of this subsection, a "Noneligible Member" is any member who first became a member during a plan year commencing on or after July 1, 1996.
For plan years beginning on or after July 1, 2002, any reference to the annual salary limit under Section 401(a)(17) of the Internal Revenue Code of 1986, as amended, shall mean the EGTRRA salary limit set forth in this subsection.
Effective June 9, 2010, gross salary shall also include gross salary, as described above, for services, but paid by the later of two and one-half (2 1/2) months after a firefighter's severance from employment or the end of the calendar year that includes the date the firefighter terminated employment, if it is a payment that, absent a severance from employment, would have been paid to the firefighter while the firefighter continued in employment with the participating municipality.
Effective June 9, 2010, any payments not described above shall not be considered gross salary if paid after severance from employment, even if they are paid by the later of two and one-half (2 1/2) months after the date of severance from employment or the end of the calendar year that includes the date of severance from employment, except payments to an individual who does not currently perform services for the participating municipality by reason of qualified military service within the meaning of Section 414(u)(5) of the Internal Revenue Code of 1986, as amended, to the extent these payments do not exceed the amounts the individual would have received if the individual had continued to perform services for the participating municipality rather than entering qualified military service.
Effective June 9, 2010, back pay, within the meaning of Section 1.415(c) -2(g)(8) of the Income Tax Regulations, shall be treated as gross salary for the year to which the back pay relates to the extent the back pay represents wages and compensation that would otherwise be included in this definition.
Effective for years beginning after December 31, 2008, gross salary shall also include differential wage payments under Section 414(u)(12) of the Internal Revenue Code of 1986, as amended;
