In the preparation of its budget, a county may not increase the county tax levy to be apportioned among its constituent municipalities in excess of 2.5% or the cost-of-living adjustment, whichever is less, of the previous year's county tax levy, subject to the following exceptions:
The approval procedure in this subsection shall not apply to appropriations adopted for a purpose referred to in subsection d. or f. below;
In the first full year where an existing appropriation or expenditure that is subject to budget limitations is made an exception to budget limitations, a county shall deduct from its final appropriations upon which its permissible expenditures are calculated pursuant to section 2 of P.L.1976, c.68 (C.40A:4-45.2) the amount which the county expended for that purpose during the last full budget year, or portion thereof, in which the purpose so excepted was funded from appropriations in the county budget.
In the first full year where an existing appropriation or expenditure that is not subject to budget limitations is made subject to budget limitations, a county shall add to its final appropriations upon which its permissible expenditures are calculated pursuant to section 2 of P.L.1976, c.68 (C.40A:4-45.2) the amount which the county expended for that purpose during the last full budget year, or portion thereof, in which the purpose so excepted was funded from appropriations in the county budget.
Notwithstanding the provisions of section 10 of P.L. 2007, c. 62 (C.40A:4-45.45) to the contrary, after a county has made the determination to prepare its budget under the property taxation limitations of section 4 of P.L.1976, c.68 (C.40A:4-45.4), pursuant to paragraph (1) of subsection a. of section 10 of P.L. 2007, c. 62 (C.40A:4-45.45), then in any such local budget year, if a county's appropriations for debt service are less than the prior year's appropriations for debt service, which amounts are exceptions to the 2.5% county tax levy increase limitation pursuant to this section, then the county's maximum permissible tax levy for that local budget year shall not be reduced by the amount of the difference in appropriations for debt service between the two local budget years.
