How to Compute 13th Month Pay for Resigned Employees

Resigning from a job in the middle of the year raises one question almost every departing employee asks HR at some point: "Will I still get my 13th month pay, or did I lose it by leaving before December?" The short answer is that resignation does not forfeit the benefit. Under Philippine labor law, 13th month pay is earned month by month as an employee works, not awarded as a lump-sum reward for still being on the payroll come Christmas. Someone who resigns in March, June, or October has already earned a proportionate share of it, and that share must be paid out — usually much sooner than December 24. This guide walks through exactly how that prorated amount is computed, when the law requires it to be released, and works through a complete numerical example so you can check your own final pay against the correct figure.

Resignation Does Not Cancel Your 13th Month Pay

13th month pay is governed by Presidential Decree No. 851 (PD 851), which requires all private-sector employers to pay rank-and-file employees a 13th month pay equivalent to one-twelfth of the basic salary earned within the calendar year. Crucially, the decree's implementing rules make clear that the benefit is earned proportionately as service is rendered — it is not conditioned on the employee remaining employed through year-end. The only service requirement is that the employee must have worked for at least one month during the calendar year in question. An employee who resigns after four months of service, or fourteen months of service that includes a partial final year, is entitled to a 13th month pay for whatever portion of that calendar year was actually worked.

This matters because some employers mistakenly tell departing staff that 13th month pay is "only for employees who are still here in December," or that resigning forfeits the benefit for the current year entirely. That position has no basis in PD 851 or in DOLE's implementing guidelines. Whether an employee resigns voluntarily, is terminated for cause, reaches the end of a fixed-term contract, or is separated due to redundancy, the same rule applies: 13th month pay is prorated based on basic salary actually earned during the months of active service within that calendar year, and it must still be paid.

The only employees excluded from 13th month pay entirely are those explicitly carved out by PD 851 and its implementing rules — managerial employees (those whose primary duty is to manage the establishment or a department, and who have the authority to hire, discipline, or recommend such actions regarding other employees), government employees, and certain categories such as those already receiving an equivalent benefit under existing company practice that is not less favorable than what PD 851 requires. Rank-and-file employees who resign are not on that exclusion list.

The Pro-Ration Formula: Total Basic Salary Earned Divided by 12

The formula for 13th month pay never changes, whether the employee works the full year or resigns partway through:

13th Month Pay = Total Basic Salary Actually Earned During the Calendar Year ÷ 12

For an employee who works the entire calendar year without interruption, this is straightforward — it is simply one month's basic salary, since twelve months of pay divided by twelve equals one month's worth. For a resigned employee, the numerator changes: instead of twelve months of full salary, the numerator is whatever basic salary was actually paid out from January 1 (or the employee's hire date, if hired mid-year) up to the employee's last actual day of work. The denominator, however, always stays fixed at 12 — it does not shrink to match the number of months worked. This is the detail that trips up a lot of people doing the math by hand: you are not dividing by "the number of months I worked," you are always dividing by 12, no matter how few months were actually rendered.

What Counts as "Basic Salary" in the Computation

Only basic salary is used in the numerator — the fixed compensation paid for ordinary working days, excluding anything considered a supplement or premium on top of it. This generally includes:

• Regular monthly or daily basic pay for days actually worked
• Basic pay for approved paid leave (such as earned service incentive leave actually used and paid)
• Cost-of-living allowances, in jurisdictions or company policies where these are integrated into basic pay by law or contract

What Is Excluded from the Computation

The following are not part of "basic salary" for 13th month pay purposes and must be excluded, even though they may appear on the same payslip:

• Overtime pay and premium pay for rest days or holidays
• Night shift differential
• Cash value of unused leave credits paid out on separation
• Allowances not integrated into basic pay (transportation, meal, or representation allowances paid separately)
• Profit-sharing payments, commissions that are not part of a fixed basic wage structure, and discretionary bonuses
• Overtime, holiday, and premium pay differentials of any kind

For any month in which the employee was absent without pay, went on leave without pay, or was suspended, the basic salary for that month is reduced accordingly before it is added into the numerator — because the formula only counts basic salary the employee actually earned, not the nominal monthly rate on the employment contract. This is exactly why two employees on the same ₱25,000 monthly salary who resign on the same date can end up with slightly different 13th month pay figures, if one of them took unpaid leave during the year and the other did not.

When Must It Be Paid? DOLE Labor Advisory No. 06, Series of 2020

For employees who remain employed through the year, 13th month pay is released on or before December 24, as PD 851 requires. But a resigned employee has already left the company well before that date, so waiting until December makes no sense — and the law does not ask them to wait. Instead, the prorated 13th month pay due to a resigned employee is treated as part of that employee's final pay, governed by DOLE Labor Advisory No. 06, Series of 2020 ("Guidelines on the Payment of Final Pay and Issuance of Certificate of Employment").

Labor Advisory No. 06-20 sets a general rule that final pay — which includes unpaid basic salary for days actually worked, the cash equivalent of unused service incentive leave, pro-rated 13th month pay, separation pay if applicable, tax refunds, and any other amount owed to the employee — should be released within thirty (30) calendar days from the date of separation or termination of employment, unless a more favorable company policy, individual employment contract, or collective bargaining agreement provides for an earlier release. The advisory also directs employers to issue a Certificate of Employment within three (3) days of an employee's request, a separate but related obligation that often comes up at the same time as final pay processing.

In practice, this means a resigned employee should not be told "wait until December" for their prorated 13th month pay. It should arrive folded into the final pay package — typically alongside the last salary, unused leave conversion, and any other amounts due — within 30 days of the effective date of resignation (or the last day actually worked, whichever the company's clearance process uses as the reference point). Employers commonly tie release of final pay to completion of the clearance process (turnover of company property, settlement of cash advances or loans, and sign-off from relevant departments), and the 30-day window is understood to run against that backdrop — but delays caused purely by administrative slowness, rather than a genuinely unresolved clearance issue, are not an acceptable reason to miss the 30-day target under the advisory.

It is also worth noting that if a company has already paid out a mid-year 13th month advance (some employers split the benefit into two releases, for example half in May or June and the balance in December, as a matter of internal policy), that advance is deducted from whatever prorated amount is computed at resignation. The employee is only entitled to the difference between the full prorated amount owed and whatever has already been advanced.

Full Worked Example: Resigning Mid-Year

To make the formula concrete, consider Maria Santos, a Junior Accountant earning a monthly basic salary of ₱30,000. Maria has been employed since January 1, 2026, and resigns effective August 15, 2026 — her last actual day of work. During the year, she also took three days of unpaid leave in April. Because payroll at her company uses 26 working days per month as the standard divisor for daily-rate computations, her daily rate works out to ₱30,000 ÷ 26 = ₱1,153.85.

Here is how her basic salary earned breaks down month by month:

Adding these eight months together gives Maria's total basic salary actually earned for 2026:

₱30,000.00 + ₱30,000.00 + ₱30,000.00 + ₱26,538.45 + ₱30,000.00 + ₱30,000.00 + ₱30,000.00 + ₱15,000.05 = ₱221,538.50

Applying the formula, Maria's prorated 13th month pay is:

₱221,538.50 ÷ 12 = ₱18,461.54

Notice that even though Maria worked roughly 7.5 months out of 12, her 13th month pay is not simply 7.5/12 of her monthly salary (which would be a slightly different number due to the April unpaid leave deduction) — it is precisely her actual earned basic salary for the year, divided by the fixed denominator of 12. This is the version of the formula that correctly accounts for absences, unpaid leave, and partial months, and it is the version DOLE examiners and payroll auditors will expect to see if the computation is ever questioned.

Under Labor Advisory No. 06-20, Maria's employer should include this ₱18,461.54 as part of her final pay, released within 30 days of her August 15 separation date — not held until December. If her final pay also includes unused leave conversion, last salary for days worked in August not yet paid, and any other amounts due, the ₱18,461.54 in prorated 13th month pay is simply one line item within that larger final pay computation.

Tax Treatment of Prorated 13th Month Pay

Under the TRAIN Law (Republic Act No. 10963), the first ₱90,000 of combined 13th month pay and other benefits (such as Christmas bonus or other similar bonuses) received within the calendar year is exempt from income tax. Only the amount in excess of ₱90,000 is added to the employee's taxable income and subject to withholding tax under the BIR's progressive tax brackets.

In Maria's case, her prorated 13th month pay of ₱18,461.54 is well below the ₱90,000 exemption threshold. Assuming she received no other bonuses that year that would combine with it to push the total over ₱90,000, the full ₱18,461.54 is tax-exempt and should be released to her in full, with no withholding tax deducted from that specific amount.

If, however, an employee's prorated 13th month pay combined with other bonuses received during the year (a mid-year bonus, a performance bonus, or a de minimis excess, for example) exceeds ₱90,000, only the excess over ₱90,000 is treated as taxable compensation. That excess is added to the employee's other taxable income for the year and subjected to the applicable annual tax bracket under the TRAIN Law — ranging from 0% for annual taxable income up to ₱250,000, up through 35% for annual taxable income above ₱8,000,000 — with the employer applying withholding tax on the excess portion before release, subject to year-end adjustment.

Common Mistakes Employers Make

Several recurring errors show up when employers compute 13th month pay for resigned staff, and it is worth knowing what to check for on a final payslip:

• Using the current monthly rate instead of actual basic salary earned. Some payroll staff simply take (months worked ÷ 12) × current monthly salary, which produces the wrong figure whenever the employee had a salary increase mid-year, took unpaid leave, or had unpaid absences — the formula must use what was actually earned each month, not a flat extrapolation.
• Withholding 13th month pay pending clearance indefinitely. Clearance procedures are legitimate, but they cannot be used to delay final pay, including 13th month pay, beyond the 30-day window set by Labor Advisory No. 06-20 without a genuinely unresolved accountability.
• Telling resigned employees they forfeited the benefit. As explained above, this has no legal basis for rank-and-file employees who worked at least one month in the calendar year.
• Failing to net off a mid-year 13th month advance correctly. If part of the benefit was already paid earlier in the year, only the remaining balance should appear in the final pay computation — but it must still be shown and reconciled, not simply omitted.
• Including overtime, holiday premiums, or allowances in the basic salary figure.This inflates the 13th month pay above what the law requires, or — more commonly in disputes — an employer excludes legitimate basic salary components, understating what is owed.

Frequently Asked Questions

If I resign in June, do I still get 13th month pay for the months I worked?

Yes. As long as you worked at least one month during the calendar year and are classified as a rank-and-file employee, you are entitled to a prorated 13th month pay based on the basic salary you actually earned from January 1 (or your hire date) through your last day of work. Resignation does not forfeit this benefit.

Do I have to wait until December 24 to receive it?

No. For employees who resign or are separated during the year, the prorated 13th month pay is released as part of final pay, which DOLE Labor Advisory No. 06-20 requires to be paid within 30 calendar days from the date of separation, not held until the standard December 24 deadline that applies to employees still on the payroll at year-end.

Is my prorated 13th month pay taxed?

Only if it, combined with any other bonuses you received during the year, exceeds ₱90,000. The first ₱90,000 of combined 13th month pay and other benefits is tax-exempt under the TRAIN Law. Any amount above that threshold is added to taxable income and subject to withholding tax based on the applicable annual tax bracket.

What if I took unpaid leave or had unauthorized absences during the year?

Those days are deducted from your basic salary for the month in which they occurred, which reduces the numerator in the 13th month pay formula for that month. The computation always reflects basic salary actually earned, not your nominal contractual monthly rate.

What can I do if my employer refuses to pay my prorated 13th month pay?

You may file a complaint with the Department of Labor and Employment (DOLE) through its Single Entry Approach (SEnA) desk, which handles labor standards disputes including unpaid or underpaid 13th month pay and final pay. Keep copies of your payslips, employment contract, and resignation letter or clearance documents, as these will support your claim during conciliation-mediation.

Does it matter whether I resigned voluntarily or was terminated?

No. The prorated 13th month pay entitlement applies the same way whether separation from employment results from voluntary resignation, termination for cause, end of a fixed-term contract, or redundancy — what matters is that the employee is rank-and-file and worked at least one month during the calendar year in question.
