# PAYROLL SYS
This system is based on current IRS code with Utah state tax calculation.
Input is a Comma-Seperated-File which associates the employee to pay due.
Payroll is a very complex system to code. Below is a HowTo.
From CSV this code will output employee payroll stubs as an encrypted pdf emailed out respectively.

# STEP 8 #################
create new ee payroll dir
copy new csv into ee "$ee.csv" file
# STEP 9 #################
read INPUT.xls sheet "INPUT"
each ee will have a 24x15 array called @time[$ee][]
# STEP 10 ################
