Calculate the taxes as follows:
Divide the authority's annual maximum amount by the pay period frequency to determine the interim pay period tax. For taxing jurisdictions levying on OPT, the interim pay period tax is the annual maximum amount.
Determine which comparison should be performed.
If the tax amount is to be proportioned between the municipality and its associated school district, then:
Divide each authority's effective maximum amount by the total maximum between the coterminous pair to determine each authority's coterminous rate.
Each authority's pay period tax equals the calculated pay period tax (see above) multiplied by the coterminous rate.
Each authority's pay period tax should be rounded down to the nearest cent, to ensure annual caps are not exceeded.
Example 1:
Employee A previously worked in Ben Avon Borough in Allegheny county and already has a $10 OPT withheld. The employee now works in Brackenridge Borough/Highlands School District, and is paid on a bi-weekly pay period. This coterminous pair mandates an actual OPT of $10 - $5 for Brackenridge Borough and $5 for the school district. Therefore, the following calculation applies to the new worksite:
Interim pay period = $ 10 annual OPT cap
Interim total service tax = ($10.00 interim pay period tax) + ($10 'OT') + ($0 'YT') = $20.00
The interim total service tax is greater than the OPT annual cap of $10, therefore
($10 annual OPT cap) - ($0 'YT'+$10 "OPT") = $0 pay period tax
Brackenridge Borough and Highlands SD each receive $0 pay period tax
Example 2:
Employee B previously worked in Ben Avon Borough in Allegheny county and already has $10 OPT withheld. The employee now works in Pittsburgh/Baldwin-Whitehall School District, and is paid on a bi-weekly pay period. This coterminous pair mandates an annual LST of $52-$47 for Pittsburgh and $5 for the school district. Therefore, the following calculation applies to the new worksite:
Interim pay period tax = $52/26 pay periods = $2
Interim total service tax = $2 interim pay period tax + $10 "OT" = $0 "YT" = $12
The interim total service tax is less than the annual cap of $52 therefore,
$ "YT" + $2 interim pay period tax = $2 < $52 authority maximum
Pittsburgh's coterminous rate = $47 / $52 = 0.903846; Baldwin-Whitehall SD's coterminous rate = $5 / $52 = 0.096154
Pittsburgh's pay period tax = $2 x 0.903846 = $1.80, rounded down
Baldwin-Whitehall SD's pay period tax = $2 x 0.096154 = $0.19 rounded down
Example 3:
Employee C has worked in other Pennsylvania taxing jurisdictions and already had $10 OPT withheld and $3.98 LST withheld. The employee now works in Fawn Township/Highlands School District, and is paid on a bi-weekly pay period. This coterminous pair mandates an annual LST of $20 - $15 for Fawn Township and $5 for the school district. Therefore, the following calculation applies to the new worksite:
Interim pay period tax = $20 / 26 pay periods = $0.77
Interim total service tax = .77 interim pay period tax + $10 "OT" + $3.98 "PT" + $0 "YT" = $14.75
The interim total service tax is less than the annual cap of $52 therefore,
$0 "YT" + .77 interim pay period tax = .77 < $20 authority maximum
Fawn Township's coterminous rate = $15 / $20 = .75; Highlands SD coterminous rate = $5 / $20 = .25
Fawn Township's pay period tax = .77 x .75 = .57, rounded down
Highland SD's pay period tax = .77 x .25 = .19, rounded down
