How does payroll software classify de minimis benefits like rice and transportation allowances differently from taxable allowances in the Philippines?

Omni HR tells de minimis benefits, like rice, medical cash, and laundry allowances within BIR's limits, apart from taxable allowances, and applies the right tax treatment to each automatically. HR doesn't need to keep a separate tax classification table, and it all flows into the year-end BIR 2316.
