Overview
Every Filipino employee in the private sector is owed a thirteenth month of pay each year. It is not a bonus, not a custom, and not something a company decides to offer. It is a statutory benefit under Presidential Decree 851, in force since 1975, and it applies to a remote employee working for a foreign client exactly as it applies to a cashier in Manila.
Foreign businesses hiring in the Philippines tend to meet the thirteenth month one of two ways. Either the provider employing the worker builds it into the invoice and the client never thinks about it again, or the client engages the person directly, learns about it in December, and finds an unbudgeted month of salary due by Christmas Eve.
This article covers who is entitled, how the amount is computed, when it is paid, how it is taxed, and what it does to the annual cost of a hire. The numbers are the government's own.
What the law says
Presidential Decree 851 requires every private-sector employer to pay rank-and-file employees a thirteenth month pay equal to one-twelfth of the basic salary they earned in the calendar year. The original decree only covered workers earning up to 1,000 pesos a month; Memorandum Order 28 removed that ceiling in 1986, so the benefit now reaches every rank-and-file employee regardless of pay.
The qualifying threshold is short. An employee who has worked at least one month in the calendar year is entitled to a proportionate amount, whether they are still employed on December 24 or resigned in March. The Department of Labor and Employment restated all of this in its December 2025 guidelines, along with a compliance report every employer must file online by January 15 of the following year.
The exclusions are narrow. Government employees, household workers, and managerial employees, meaning those with the authority to hire, fire, discipline and set policy, are outside the decree. So are workers paid purely on commission or per task with no guaranteed wage. An employer that already pays a thirteenth month or its equivalent under another name is deemed compliant. There is no exemption for financial hardship; the guidelines say that no applications for exemption or deferment are entertained.
A remote customer support agent, bookkeeper, designer or virtual assistant on a monthly salary is rank-and-file. They are covered.
How it is computed
The formula is the whole of the rule:
Thirteenth month pay = total basic salary earned in the calendar year ÷ 12
"Basic salary" is the fixed wage for work done. It excludes overtime, holiday premiums, night-shift differential, cost-of-living allowances, and cash conversions of unused leave, unless the employment contract or company practice folds those into the basic pay. Salary paid during maternity leave counts.
Three worked examples, in pesos:
- Full year, flat salary. An employee paid 35,000 pesos a month for all twelve months earned 420,000. Divided by twelve: 35,000 pesos, due by December 24. For a full-year employee on a fixed wage, the thirteenth month simply equals one month's basic pay.
- Mid-year hire. Someone who started on July 1 at 40,000 a month earned 240,000 over six months. Divided by twelve: 20,000 pesos. Half a year of service, half a month of pay.
- Resignation. An employee on 30,000 a month who resigned at the end of April earned 120,000. Their proportionate thirteenth month is 10,000 pesos, released with their final pay, not held until December.
Employers may split the payment, paying half before the school year opens in June and the balance by December 24, but the full amount must land by that date.
How it is taxed
Under the tax code as amended by the TRAIN law, thirteenth month pay and other benefits are exempt from income tax up to a combined ceiling of 90,000 pesos a year. Only the portion above that is taxed. At the salary levels typical of remote roles, the thirteenth month arrives untaxed, which is part of why employees value it so highly.
The employer's obligation does not end at the payment. The thirteenth month appears in the employee's annual tax certificate, and the compliance report to the labor department is a separate filing with its own deadline.
What it does to the cost of a hire
For a foreign business, the thirteenth month is best understood as a line in the annual cost, not a December surprise. A salary of 35,000 pesos a month is 420,000 a year in base pay and 455,000 with the thirteenth month, an addition of 8.33 percent.
It sits beside the other statutory costs of a Philippine employment. In 2026, the employer's share of social security is 10 percent of the monthly salary credit, capped at a credit of 35,000 pesos; the employer's share of national health insurance is 2.5 percent of basic salary; the employer's share of the housing fund is 2 percent, capped at 200 pesos a month. On that same 35,000-peso salary the employer contributions come to roughly 4,575 pesos a month, another 13 percent. Together with the thirteenth month, a Filipino employee's base salary carries about 21 percent of mandatory additions before any allowances, equipment or provider fee.
The practical consequence is that any quote which shows only a monthly salary is understating the true cost by about a fifth. A business comparing a direct contractor arrangement against employment through a provider should compare like with like: the employment number includes the thirteenth month and the contributions, the contractor number includes neither, and the contractor number carries the reclassification risk that comes with it.
Who actually pays it
The thirteenth month is owed by the legal employer. Which party that is depends on how the hire was structured.
When a foreign company engages a Filipino as an independent contractor, there is no thirteenth month, because there is no employer. That is the legal position, and it holds only as long as the person genuinely is a contractor; a worker who keeps fixed hours, uses the company's systems and answers to its managers is an employee in the eyes of the labor department regardless of the contract, and the unpaid thirteenth months become back pay.
When the person is employed through a Philippine employer of record or a staffing provider that employs its placements, the obligation sits with that employer. The client's invoice is meant to cover it. On Flex's managed model the placement is employed by Flex in the Philippines, with the contract, payroll and statutory obligations on Flex's side and the day-to-day direction on the client's; the arrangement is set out for anyone hiring through Flex, with the fee structure on the pricing page. A client evaluating any provider should ask the same two questions: who is the legal employer, and is the thirteenth month inside the price or billed on top in December.
When the company has its own Philippine entity, it is the employer, it computes and pays the thirteenth month itself, and it files the January report.
Conclusion
The thirteenth month is not optional and not complicated. One-twelfth of the year's basic salary, to every rank-and-file employee with at least a month of service, paid by December 24, tax-free up to the 90,000-peso ceiling, with a compliance report by January 15. For a full-year employee on a fixed wage it is one extra month of pay.
The only real decision for a foreign business is where the obligation sits: with the company itself, with a Philippine employer on record, or nowhere at all because the person is a genuine contractor. Whichever it is, the honest annual cost of a Filipino hire is thirteen salaries plus the employer contributions, and a budget built on twelve will be wrong by Christmas.
