One salary, fourteen paydays: how 13th month pay works
By Skyler Bissell · August 17, 2026 · 9 min read
In Madrid, a €129,000 year arrives as fourteen payments of €9,214. In Berlin, the identical year is twelve payments of €10,750. Nobody in either city earned a euro more than the other. The calendar just cut the same annual salary into a different number of slices, and if you compare the two monthly figures without knowing that, Madrid looks 14% poorer than it is.
That reading error is common enough to have cost people real money in negotiations, because a large part of the world pays salaries in 13 or 14 instalments and quotes offers by the month. Here is what the extra payment is, where it is required, and the one division you should do before comparing any two offers.
13th month pay is an extra salary payment, usually equal to one month's pay, that many countries require by statute or near-universal collective agreement, typically paid in December. It is part of the contractual annual package: a Spanish or Portuguese year has 14 payments, a Brazilian or Filipino year has 13, and the annual total is what the offer is worth.
TL;DR
- A 13th month is your own salary on a different schedule. Multiply the monthly figure by the payment count before comparing anything. The division.
- A monthly quote from a 14-payment country reads about a seventh lower than the same annual salary quoted in twelfths. Seven cities, one year.
- In the Philippines and Austria the schedule changes the tax bill, in your favour. Where the taxman joins in.
Where 13th month pay is the law
Three tiers, and the difference between them decides whether the payment can ever be taken away.
Required by statute. These are the countries where the extra payment is a legal entitlement, enforceable like wages:
- The Philippines: Presidential Decree 851, per the DOLE handbook, one twelfth of basic salary earned in the year, paid by December 24.
- Brazil: the gratificacao natalina under Law 4.090 of 1962, paid in two instalments by November 30 and December 20. Brazil also adds a constitutional vacation bonus of one third of a month, so a Brazilian year holds closer to thirteen and a third salaries.
- Mexico: the aguinaldo, a minimum of 15 days of salary before December 20 under Article 87 of the Ley Federal del Trabajo. Half a 13th month, as a floor.
- Argentina: the sueldo anual complementario, one extra salary paid in two halves, June and December.
- Greece: Christmas, Easter and vacation payments for private-sector employees, adding up to roughly two extra months.
- Spain: Article 31 of the Estatuto de los Trabajadores mandates two pagas extraordinarias a year, so the standard Spanish calendar is 14 payments. Many contracts prorate them back into 12; the annual total is identical either way.
- Portugal: the subsidio de ferias and subsidio de Natal under the Codigo do Trabalho, 14 payments.
Required in practice by collective agreement. Italy's tredicesima comes from the sector CCNL, with no statute behind it, and some sectors (banking is the famous one) add a quattordicesima. Austria's 13th and 14th salaries, the Urlaubszuschuss and Weihnachtsremuneration, come from collective agreements that cover about 98% of Austrian employees, per the Austrian Economic Chambers (WKO). In both countries you should assume the extra payments exist unless the contract says otherwise.
Customary and negotiable. German Weihnachtsgeld, Dutch and Nordic year-end gratuities beyond the statutory minimums, and every US year-end bonus. These are contract terms. They can be generous and they can vanish, and no labor inspector will chase them. One near-miss worth knowing: the Netherlands mandates an 8% holiday allowance on top of stated salary, which behaves like a small statutory 13th month by a different name. That one deserves its own explainer.
The same year, cut differently
To make the slicing visible, here is one household, the single earner on a $150,000-equivalent salary our comparison pages publish, run through our engine and paid on each city's standard calendar. The annual gross is the same life in every row. Only the per-payment figure moves.
| City | Payments a year | Why | Gross per payment |
|---|---|---|---|
| Berlin | 12 | No statutory extra payment | €10,750 |
| Madrid | 14 | Workers' Statute, art. 31 | €9,214 |
| Lisbon | 14 | Holiday and Christmas allowances | €9,214 |
| Milan | 13 | Tredicesima via sector CCNL | €9,923 |
| Sao Paulo | 13 | Law 4.090/1962 | R$60,154 |
| Manila | 13 | Presidential Decree 851 | ₱710,231 |
| Mexico City | 12.5 | 15-day aguinaldo, LFT art. 87 | MX$204,400 |
cityparity engine figures, 2026: each row is the same $150,000-equivalent single earner, converted at build-time rates, with the annual gross divided by that city's standard payment count. Mexico City is shown at the statutory minimum aguinaldo; many employers pay more. How much of each gross survives tax is a separate question, answered per country at take-home pay by country.
The same slicing applies after tax. Take-home on the Madrid year is €78,657. Spread over fourteen instalments that is €5,618 landing in the account in an ordinary month; pushed back into twelfths it would read €6,555. A Spanish payslip in February and a German one can differ by a four-digit sum between two people living the same year.
Divide before you compare
The whole trap fits in one sentence: a monthly figure means nothing until you know how many of them there are.
Multiply a Madrid monthly quote by 12 instead of 14 and you understate the offer by 14.3%. Compare a Milanese monthly against a Berlin monthly at face value and you tilt the table by 8.3% before taxes enter. On the salaries in the table above those are five-figure mistakes in euros, and recruiters in 14-payment countries quote monthly figures by habit because that is how everyone local thinks.
So the reading order for any offer letter is fixed. First find the annual gross, or build it: monthly times the payment count, plus any statutory extras the country adds (Brazil's vacation third is the one people miss). Then, and only then, compare years against years. The annual number is also the one our city-to-city comparison wants as input, because taxes, childcare and rent are all priced per year, and the engine has no interest in how the year was sliced.
One more distinction worth insisting on in writing: a 13th month is inside the package, a performance bonus is on top of it. An offer that folds a genuinely discretionary bonus into the quoted annual is doing the opposite trick of the monthly quote, dressing a maybe as a certainty. The extra payments in this post are certainties. That is exactly what makes them different from the variable pay an offer letter loves to headline, and why the fixed 13th belongs in your annualised comparison while the target bonus belongs in a footnote.
Where the schedule changes the tax
In most 13-payment countries the extra month is ordinary income. Spain and Portugal tax the pagas like any other salary; Italy withholds on the tredicesima at your normal rates. The schedule moves cash through the year without moving the annual bill.
Two countries are exceptions in the reader's favour, and one in the payslip's.
The Philippines exempts the 13th month and equivalent benefits from income tax up to PHP 90,000 a year under the TRAIN law, per the Bureau of Internal Revenue. On the Manila year in the table, the payment itself is ₱710,231, so the exemption covers a slice of it and the remainder is taxed as compensation.
Austria taxes the 13th and 14th payments at a preferential 6% up to a ceiling of one sixth of annual pay, the Jahressechstel, which pulls the average rate on the whole year down by several points for a typical employee. A disclosure: our engine prices Austrian salaries at ordinary rates and does not yet model the sechstel, so this page quotes no Austrian engine figure, and until that changes our Vienna numbers are conservative about the thing this section describes.
Brazil runs the other direction: the 13th is taxed, and withheld separately from regular salary at source, so the December deposit is smaller than a naive one-more-month guess. The annual arithmetic barely moves; the month-to-month experience does.
What to ask before you sign
Four questions cover it. How many salary payments does the contract specify, and is the quoted figure per payment or per year? Are the extra payments statutory or contractual, meaning can a future cost-cutting year delete them? Is any bonus on top genuinely variable, and what did it pay last year? And what does the annual figure become after that country's taxes, which is where the comparison usually turns over: the hidden paycheck covers the non-cash half of that answer, and the leave version of this same reading trap, a headline rate that means less than it says, is the subject of is maternity leave full pay.
If the two offers sit in two countries, run both cities through a real comparison before the call where a number gets agreed. New York vs Madrid and New York vs Sao Paulo both start from annual figures for precisely the reason this page exists.
FAQ
Is 13th month pay a bonus?
No. A 13th month payment is part of your contractual annual salary, paid on a schedule the law or a collective agreement fixes, and in the countries that require it an employer cannot skip it the way a discretionary bonus can be skipped. A performance bonus sits on top of the annual package; a 13th month is inside it. That is why annualising the offer is the honest way to compare: the 13th month disappears into the annual total, where it belongs.
Which countries require a 13th month salary?
By statute: the Philippines (Presidential Decree 851), Brazil (Law 4.090 of 1962), Mexico (a 15-day aguinaldo under Article 87 of the federal labor law), Argentina (the sueldo anual complementario, paid in two halves), Greece (Christmas, Easter and vacation payments for private-sector employees), Spain (two extraordinary payments under Article 31 of the Workers' Statute) and Portugal (holiday and Christmas allowances, 14 payments in total). Through near-universal collective agreements: Italy's tredicesima and Austria's 13th and 14th salaries. Germany, the Netherlands, the UK and the US require none, though German Weihnachtsgeld is a common contract term.
Is 13th month pay taxable?
Usually it is ordinary salary and taxed like any other month. Two exceptions matter. In the Philippines, the 13th month and equivalent benefits are tax-exempt up to PHP 90,000 a year under the TRAIN law. In Austria, the 13th and 14th payments are taxed at a preferential 6% up to a ceiling of one sixth of annual pay, which is a real reduction in the average rate on the whole year. Brazil withholds tax on the 13th separately from regular salary, which changes the December payslip without changing the annual bill much.
Do expats get 13th month pay?
Yes, if you are employed under a local contract in a country that mandates it. The entitlement follows the employment contract and local labor law; nationality plays no part. That includes employment through an employer-of-record: an EOR contract in the Philippines or Brazil carries the 13th month like any other local contract, and the EOR's quoted employment cost should already include it. A contractor invoicing a foreign company is outside the labor law and gets nothing unless the contract says so.
