Assisted ZARA payroll (ISAI) in fixing the issue of SSS computation on their ERIC. Upon checking the maintenance on the computation basis for the government deduction is not correct. As per the users government computation basis should be based on the gross income, but when they computed the batch the computation basis for the government is based on the basic. When we checked the compuation basis on the test database, it is based on the gross income which has the correct compuation. Upon checking on the tax maintenance of the user, the taxable income is ticked which maybe the cause why the computation is wrong. As per the user they will maintain the computation basis using the gross income and retransact the payroll for May and June on the test database then transact the payroll for June on the LIVE to see if the computation will be the same since the maintenance on the test database is correct.
