📝 How Christmas Bonuses Work Worldwide

A Christmas bonus — also known as 13th salary, aguinaldo, year-end bonus, or December bonus — is an extra payment made to employees at or near the end of the calendar year. In many countries it is required by labor law; in others it is a customary practice backed by collective agreements or company policy.

The concept originated in Italy in the early 20th century as a Christmas gratuity (gratifica natalizia) and spread worldwide. Today, over 30 countries have some form of mandatory or customary year-end bonus, though the rules differ significantly:

• Amount: ranges from 15 days of salary (Mexico) to a full extra month (Brazil, Philippines, Spain, Italy, Portugal) to performance-based discretionary amounts (USA, UK).
• Taxation: some countries exempt a portion (Mexico exempts 30x UMA, Philippines exempts up to 90,000 PHP), others tax it as regular income (Germany, Spain, Italy).
• Timing: most pay in December, but some split it across the year (Argentina pays half in June, half in December; Peru pays in July and December; Brazil pays in two installments in November and December).
• Proportional rights: nearly all countries grant a proportional bonus for partial-year workers, so if you started mid-year you still receive a partial payment.

While the names and rules differ, the underlying principle is the same worldwide: employees receive extra compensation at year-end, typically equivalent to one month of salary. Below is a comprehensive breakdown of how this works across 16+ countries.

The table below summarizes mandatory and customary year-end bonus rules worldwide. “Mandatory” means required by law; “Customary” means widely expected but not legally required.

While each country has its own specific rules, the general formula for calculating a Christmas bonus is:

Bonus = Monthly salary × (months worked / 12)

This means that if you worked the full year, you receive the full bonus amount (typically one month of salary). If you worked part of the year, the bonus is prorated based on the months or days you worked.

Mexico example (Aguinaldo)

Mexico uses a day-based formula. The legal minimum is 15 days of daily salary:

1. Daily salary = Monthly salary / 30. For example, 9,000 MXN / 30 = 300 MXN/day.
2. Aguinaldo days = 15 / 365 × days worked. For a full year: 15 days.
3. Gross aguinaldo = Daily salary × aguinaldo days. For 15 days at 300 MXN: 15 × 300 = 4,500 MXN.
4. ISR exemption = 30 × UMA = 30 × 117.31 = 3,519.30 MXN (2026).
5. Taxable portion = 4,500 − 3,519.30 = 980.70 MXN (only this amount is subject to ISR).

For exact Mexico calculations including ISR tables, use the Aguinaldo Calculator (Mexico).

Brazil example (13º Salário)

Brazil uses a simpler month-based formula. The legal minimum is one full extra month of salary:

1. Full 13th salary = Monthly salary. For example, if you earn 3,000 BRL/month, your gross 13th salary is 3,000 BRL.
2. Proportional (partial year) = Monthly salary × (months worked / 12). If you worked 6 months: 3,000 × 6/12 = 1,500 BRL.
3. Deductions: INSS (7.5–14%) and IRRF (0–27.5%) are withheld from the 13th salary.
4. Payment schedule: The first installment is paid by November 30 (no advance INSS/IRRF), and the second by December 20 (with INSS and IRRF deductions).

General formula for other countries

For countries not listed above, the general approach is:

• Spain, Portugal, Italy, Greece: The bonus equals one extra month of salary (or two, in Spain and Portugal). It is paid in December (and sometimes also in summer).
• Philippines: 13th month pay = total basic salary earned within the calendar year / 12. Tax-exempt up to 90,000 PHP.
• Argentina, Colombia: The bonus (SAC / prima) equals one month, split into two halves paid in June and December.
• Germany, Japan, USA, UK: No legal minimum. Check your employment contract or collective bargaining agreement for the amount.

The tax treatment of Christmas bonuses varies widely. Here are the key rules for major countries:

Mexico — ISR Exemption

The aguinaldo is exempt from ISR (Income Tax) up to 30 times the UMA. In 2026, the daily UMA is 117.31 MXN, so the exemption is 3,519.30 MXN. If your aguinaldo exceeds this amount, only the excess is taxed at your marginal ISR rate. Most low- and middle-income workers pay little or no ISR on their aguinaldo.

Brazil — INSS + IRRF

The 13th salary (décimo terceiro) is subject to INSS (social security, 7.5–14%) and IRRF (income tax, 0–27.5%). Deductions are withheld from the second installment (paid by December 20). The first installment (by November 30) is paid in full without advance deductions. The IRRF is calculated separately from regular monthly salary using the progressive tax table.

Philippines — Tax-Exempt Threshold

13th month pay and other benefits up to 90,000 PHP per year are tax-exempt. If your 13th month pay exceeds this threshold, only the excess is taxable. This means most rank-and-file employees in the Philippines pay no income tax on their Christmas bonus.

Germany — Weihnachtsgeld Taxation

In Germany, Weihnachtsgeld (Christmas bonus) is not legally required but is received by approximately 55% of workers under collective agreements. It is taxed as regular income (Lohnsteuer) and subject to social security contributions. However, small one-time payments (up to 2,000 EUR) may qualify for a reduced flat tax rate under certain conditions.

Other countries

• Spain & Portugal: The extra pays (paga extra / subsídio) are taxed as regular income via IRPF/IRS withholding.
• Italy: The tredicesima is taxed as regular income (IRPEF), though it may push you into a higher bracket for that month.
• Costa Rica: The aguinaldo is fully tax-exempt, making it one of the most favorable countries for year-end bonuses.
• USA: Bonuses are treated as supplemental wages, subject to a federal flat withholding rate of 22% (plus state tax).
• UK: Bonuses are taxed via PAYE as regular income.

1. Learn that Christmas bonuses go by many names worldwide: 13th salary, aguinaldo, tredicesima, SAC, prima, and Weihnachtsgeld. They typically equal one extra month of pay.
2. Review the 16-country comparison table to see if your country legally requires a year-end bonus and what the minimum amount is.
3. The general formula is: bonus = monthly salary x (months worked / 12). Mexico uses daily salary x 15 days. Brazil uses one full month.
4. Check your country's tax rules: Mexico exempts 30x UMA, Philippines exempts up to 90,000 PHP, Brazil deducts INSS and IRRF, Germany taxes it as regular income.
5. For exact calculations, use a country-specific tool such as the Mexico Aguinaldo Calculator or Brazil 13th Salary Calculator.

What is a Christmas bonus?

A Christmas bonus (also called 13th salary, aguinaldo, or year-end bonus) is an extra payment made to employees at the end of the year. In many countries it is required by law; in others it is a customary practice. The amount is typically equivalent to one month of salary, but rules vary by country.

Which countries legally require a Christmas bonus?

Christmas bonuses are mandatory in Mexico (aguinaldo, 15 days minimum), Brazil (13th salary, 1 full month), the Philippines (13th month pay), Spain (paga extra), Portugal, Italy (tredicesima), Greece (doro), Argentina (SAC), Colombia (prima), Costa Rica, Peru, and Uruguay. In Germany and Japan, it is customary but not legally required. In the USA and UK, it is entirely discretionary.

How is the Christmas bonus calculated?

The most common method is: bonus = monthly salary × (months worked / 12). In Mexico, it is calculated as daily salary × 15 days (or proportional). In Brazil, the 13th salary equals one full month of pay. In the Philippines, it is 1/12 of total annual basic salary. Each country has specific rules for partial-year workers.

Is the Christmas bonus taxable?

In most countries, the Christmas bonus is taxable. Mexico exempts up to 30 times the UMA (about 3,519 MXN in 2026). Brazil deducts INSS and IRRF from the 13th salary. In the Philippines, 13th month pay up to 90,000 PHP is tax-exempt. In Germany, Weihnachtsgeld is taxed as regular income. Always check local tax rules for your situation.

Do I get a proportional bonus if I started mid-year?

Yes. Nearly all countries with mandatory bonuses grant a proportional amount for partial-year workers. For example, if you worked 6 months in Mexico, you get 15/365 × 180 = 7.4 days of aguinaldo. In Brazil, you receive 6/12 of the 13th salary. Check your local labor law for the exact proration formula.

When should I receive my Christmas bonus?

Payment dates vary by country. Mexico requires payment by December 20. Brazil pays in two installments (by November 30 and December 20). The Philippines requires payment by December 24. Most European countries pay in December. Argentina and Colombia split the bonus into two halves (June and December).

When dealing with Christmas bonuses, keep these points in mind:

• Check your contract: In customary countries (Germany, Japan, USA, UK), the bonus amount is often defined in your employment agreement or collective bargaining contract. Do not assume an amount without checking.
• Proportional rights: If you started mid-year, most countries grant a proportional bonus. For example, if you worked 6 months in Mexico, you get 15/365 × 180 = 7.4 days of aguinaldo. In Brazil, you receive 6/12 of the 13th salary.
• Know your payment date: Mexico requires payment by December 20; the Philippines by December 24; Brazil in two installments. If your employer is late, you may be entitled to interest or penalties under local labor law.
• Tax timing: Some countries spread the tax impact across months (Spain, Portugal), while others deduct it all at once (Brazil second installment). Plan your cash flow accordingly.
• Resignation and severance: If you resign before December, you are still entitled to the proportional bonus for the days you worked. This should be included in your final paycheck or severance package.
