Final pay and separation pay get used interchangeably in everyday conversation, but they answer different questions. Final pay is what every departing employee is owed, regardless of why they left: unpaid salary for days already worked, a pro-rated 13th month payment for the months actually worked this year, and the cash value of any unused leave. DOLE Labor Advisory No. 06-20 recommends releasing this within 30 days of separation.
Separation pay is a different, narrower entitlement that only applies to specific "authorized causes" under the Labor Code, none of which are the employee's fault. Redundancy and installation of labor-saving devices pay the higher of 1 month's salary or 1 month per year of service. Retrenchment, closure not due to serious losses, and termination due to disease pay the higher of 1 month's salary or half a month per year of service. A fraction of at least 6 months rounds up to a full year in both formulas. Closure due to genuinely serious business losses requires no separation pay at all, and neither does just-cause dismissal or a plain resignation.
The tax treatment is where a lot of quick estimates go wrong. Separation pay for an authorized cause is completely exempt from withholding tax under Section 32(B)(6)(b) of the National Internal Revenue Code, since the law treats it as compensation for a circumstance beyond the employee's control. Final pay is different: unpaid salary is fully taxable, 13th month pay is exempt only up to the shared ₱90,000 cap, and unused leave conversion is exempt only for the first 10 days per year under the BIR's de minimis rule. This calculator combines every taxable excess into one incremental calculation against the 2026 TRAIN Law brackets, the same approach used by our standalone 13th Month Pay Calculator.
