Tax-Free Employee Gifts in Mexico 2026: The UMA Rules and the $821 Despensa Myth

Last updated: October 2026. All amounts are Mexican pesos (MXN).

Start here: there is no gift exemption

Every other country in this series has a small, friendly number you can memorise. Mexico does not have one. Nothing in the Ley del Impuesto sobre la Renta (LISR) says “a gift below X is not taxable”. There is no de minimis, no per-occasion allowance, no birthday carve-out, no Christmas concession. If you give an employee something of value and it does not fit one of the five statutory routes below, it is taxable income to them and part of their IMSS contribution base.

This catches foreign employers constantly. A company that runs a perfectly compliant €1,000 Italian fringe benefit programme lands in Mexico, sends the same digital gift card to the Guadalajara team in December, and has just created taxable remuneration with no withholding, no CFDI de nómina line and no SBC adjustment.

The whole rule in one table

This is the table to keep. Each row is a statutory route; the columns are the three questions a payroll team actually has to answer. All caps are stated in UMA and converted at the 2026 values.

Two things in that table surprise people. The first is the last row: the thing most companies instinctively reach for is the one route with no relief at all. The second is the fondo de ahorro row — it is previsión social, but article 93's último párrafo explicitly lifts it, along with medical and life insurance and pensions, out of the cap that applies to everything else. Savings funds are not competing with your despensa budget for the same ceiling.

There is also a sixth lever that English-language summaries almost never mention, because it is a social-security rule rather than a tax one: article 27 fracción VII of the Ley del Seguro Social keeps premios por asistencia y puntualidad out of the contribution base up to 10% of SBC each. It is not an ISR exemption — the employee is taxed — but for an attendance-based recognition programme it is real money, and it is the one Mexican rule that rewards selectivity rather than punishing it.

The unit everything is measured in, and why it keeps shrinking

Read the statute and you will not find the word UMA anywhere in these provisions. Article 93 fracción XIV still says the exemption runs “hasta el equivalente del salario mínimo general del área geográfica del trabajador elevado a 30 días”. Article 27 fracción XI still describes the savings-fund ceiling in salarios mínimos. The Ley del Seguro Social still writes its despensa rule the same way.

Those words no longer mean what they say. The 2016 desindexación reform to article 26, apartado B of the Constitution created the Unidad de Medida y Actualización and stopped the minimum wage being usable as a unit of account in federal law. Where a tax or social-security provision says “salario mínimo” as a measuring stick, you read UMA. INEGI updates it once a year by the December year-on-year INPC.

In 2016 the two numbers were identical — the UMA was set at the then minimum wage of $73.04. They have diverged every year since, and 2026 widened the gap by a further 3.4 points in a single year: the general minimum wage rose 13.0%, from $278.80 to $315.04 a day, while the UMA rose 3.69%, from $113.14 to $117.31.

This matters operationally, not just rhetorically. If your Mexican payroll provider is uprating exemption thresholds by the minimum-wage increase, it is over-exempting by a factor of nearly three. And if your budgeting model assumes exemptions track wage inflation, it will overstate the tax-free share of your reward spend a little more every year.

The $821.17 despensa cap is not in the law

Search for the 2026 despensa exemption in Spanish and you will repeatedly meet $821.17 a month. It is seven times the daily UMA ($117.31 × 7 = $821.17), and it is presented as the amount of vales de despensa an employee may receive tax-free each month.

Here is what the statute actually says, and why that number has no basis in it.

Article 93 fracción VIII exempts previsión social benefits granted generally. The penúltimo párrafo then adds a limit, and it is a two-stage one:

1. The test. Take the worker's wage income plus their previsión social for the year. If that total does not exceed seven times the annual unit — 7 × $42,794.64 = $299,562.48, or $24,963.54 a month — the previsión social is exempt in full.
2. The cap. If the total does exceed it, the previsión social exemption is limited to one annual unit: $42,794.64 for the year, equivalent to $3,566.22 a month. The statute also makes this a floor, so the limit never bites below that figure.

There is a second reason the confusion persists: the cap that does bind most employers is not the ISR one at all. It is the IMSS one, and it is a quarter the size.

One note of precision on that $1,426.49, because payroll systems disagree about it. The statute sets 40% of the UMA against a daily SBC, so the primitive figure is $46.92 per day. INEGI derives its monthly UMA as the daily value times 30.4, which is where $1,426.49 comes from (40% of $3,566.22). A system that multiplies by a flat 30 days instead will produce $1,407.72. Both are defensible readings of the same rule; what matters is that you apply one of them consistently and can explain which.

The despensa rail: why the card matters more than the amount

The exemption above tells you what the employee pays. A separate provision decides whether you can deduct the cost at all, and it is unusually mechanical.

Article 27 fracción XI of the LISR requires previsión social to be granted “en forma general en beneficio de todos los trabajadores”, and then adds a sentence that governs the entire Mexican voucher industry: vales de despensa are deductible only where their delivery is made “a través de los monederos electrónicos que al efecto autorice el Servicio de Administración Tributaria”.

That is not a formality. The SAT authorises issuers individually, publishes them in a register, sets what the instrument may be spent on through the Resolución Miscelánea Fiscal, and publishes a second register of issuers whose authorisation was not renewed. The relevant 2026 rules sit in section 3.3.1 of the RMF — 3.3.1.15 on permitted use and affiliated establishments, 3.3.1.16 on the legend the instrument must carry, 3.3.1.18 on how long an authorisation lasts, 3.3.1.19 on issuer obligations including the CFDI with the vales de despensa complemento, and 3.3.1.22 on publication of the register — with the technical requirements in Anexo 10, published in the Diario Oficial on 9 January 2026.

The authorised issuer list is long and includes both specialist voucher companies and retailers running their own instrument. Grouped by year of authorisation, it currently covers names such as Edenred México, Efectivale, Toka Internacional, Sí Vale México, Pluxee México, Broxel, Previsión del Trabajo, Promotora Inbursa and Omonel, alongside retailer-issued cards from Wal-Mart, Chedraui, H-E-B, S-Mart, Calimax, Alsuper and Ley. Check the register rather than this paragraph before you sign: authorisations lapse, and the SAT maintains a separate “no renovados” list precisely because they do.

The other half of the rule is the word general. Previsión social must be available on the same terms to all workers — for unionised staff, by following the collective agreement; for a company with several unions, by being uniform within each one. A despensa benefit given only to managers, or scaled by performance, is not previsión social. This is the single most common way an otherwise well-run programme loses the treatment: not the amount, not the card, but the selectivity.

The 47% you cannot deduct

Now the provision that quietly reprices every exempt benefit in Mexico. Article 28 fracción XXX makes non-deductible:

“Los pagos que a su vez sean ingresos exentos para el trabajador” — up to the amount produced by applying a factor of 0.53 to those payments. The factor drops to 0.47 where the exempt benefits granted in the year do not decrease against the immediately preceding fiscal year.

In plain terms: of every peso of exempt benefit you hand an employee, you deduct 53 centavos at best, 47 centavos at worst. The better outcome is conditional on not cutting benefits year over year — which means a company trimming its rewards budget is punished twice, once on the benefit and once on the deduction.

Set the employer's social-contribution rate to zero for a moment and the result is the opposite of what the voucher industry advertises:

On income tax alone, a despensa voucher is worse than cash for any employee below a 16.76% marginal rate — which is most of a Mexican frontline payroll. The 47% disallowance eats the exemption. That is the finding, and it is not one you will see on a voucher provider's pricing page.

Now add employer social contributions, which the despensa escapes up to 40% of UMA:

The advantage is real and large — but notice what produced it. Between the two tables, nothing changed about the income-tax exemption. The entire case for vales de despensa is the IMSS exclusion in article 27 fracción VI of the Ley del Seguro Social. Above 40% of UMA, where that exclusion stops, the economics revert to the first table. Which is the practical answer to how much despensa to give: $46.92 a day, and not obviously more.

One smaller number from the same provision, worth having: moving from the 0.53 factor to the 0.47 factor — that is, simply not reducing benefits against last year — raises efficiency from 1.164 to 1.189. 2.5 points, or 2.1% more net value delivered per peso spent, for a decision that costs nothing except holding the line on a benefits budget.

Aguinaldo, prima vacacional and PTU in practice

The aguinaldo is the one Mexican reward event every foreign employer has heard of, and the one most often mis-modelled. Article 87 of the Ley Federal del Trabajo sets the floor at 15 days of salary, payable before 20 December, pro-rated for part years. The exemption is 30 UMA, $3,519.30 — so the exemption covers the statutory minimum only for workers earning up to $234.62 a day ($3,519.30 ÷ 15).

That figure is below the 2026 general minimum wage of $315.04, which produces an odd-looking result: the minimum legal aguinaldo for a minimum-wage worker is 15 × $315.04 = $4,725.60, which is $1,206.30 above the exemption. In most countries that would be the end of it.

On the recurring question of whether the statutory aguinaldo is about to become 30 days: as of October 2026 it has not. An initiative to reform article 87 on a seniority scale was published in the Gaceta Parlamentaria in March 2026 and remains in committee; media coverage of “30-day aguinaldo in 2026” is describing a bill, not law. Plan on 15 days as the floor and treat anything above it as a contractual benefit.

Prima vacacional and PTU share the fracción XIV paragraph and each carry a 15-UMA exemption, $1,759.65 for 2026. The prima vacacional has a statutory floor of 25% of the wages for the vacation period; since the 2023 vacaciones dignas reform raised first-year vacation to 12 days, the prima is a larger number than many long-standing payroll models assume, and more of it is landing above the exemption each year as wages rise and the UMA does not.

Mexico against the rest of the series

Put the countries we have covered side by side and Mexico is structurally unlike all of them. Everywhere else, the question is “how much?” In Mexico, the question is “through which channel?”

Mexico, Spain and the United States are the three jurisdictions in this list where a gift card has no exemption to sit in — and they get there by three different routes. The US rule excludes cash equivalents from an otherwise generous concession. Spain has no de minimis and answers with an exempt catalogue of specific benefits. Mexico has no concession either, but is alone in offering a purpose-built, licensed, closed-loop instrument that does qualify. If you run one global programme across them, the country matrix is the place to start.

The compliance checklist

• Confirm your voucher issuer is in the SAT register today. Not that it was authorised once — the SAT publishes a separate list of issuers whose authorisation was not renewed, and a lapsed issuer costs you the deduction, not them.
• Check the benefit is general. Same terms for all workers, or uniform within each union under its collective agreement. Performance-scaled despensa is not previsión social.
• Size the despensa line at 40% of UMA — $46.92 a day of SBC. That is where the IMSS exclusion stops and the economics flatten out.
• Apply the right ISR cap. Full exemption below the 7-UMA annual income test ($299,562.48); 1 UMA a year ($42,794.64) above it. Not $821.17 a month.
• Hold benefits flat or growing year on year so article 28 fracción XXX gives you the 0.47 factor rather than 0.53 — worth 2.1% of delivered value for free.
• Keep the fondo de ahorro inside its own three conditions — employer match no greater than the worker's, 13% of salary, and 1.3 UMA a year ($55,633.03) — and remember it sits outside the 1-UMA previsión social cap.
• Process everything else as taxable pay. Open-loop prepaid cards, brand gift cards, hampers, raffle prizes: CFDI de nómina, withholding, SBC. There is no small-gift relief to fall back on.
• Stop uprating thresholds by the minimum wage. They move with the UMA, which rose 3.69% in 2026 against the minimum wage's 13.0%.

All amounts are Mexican pesos. The following are our own calculations from the published figures above and are not INEGI, SAT or IMSS figures: the UMA-to-minimum-wage ratios of 100.0%, 40.6% and 37.2% and the 2016, 2025 and 2026 comparison; the $5,931.90, $2,965.95 and $11,863.80 figures for exempt capacity lost to the index switch; the 7-UMA annual threshold of $299,562.48 and its $24,963.54 monthly equivalent; the observation that the income-tax headroom is 2.5 times the IMSS headroom and the $1,426.49 and $1,407.72 monthly conversions; the $2,745 of unused monthly headroom implied by budgeting to $821.17; the 1.3-UMA savings-fund figure of $55,633.03; the whole efficiency model including the 1.189 and 1.164 despensa ratios, both cash-bonus columns, the 16.76% break-even rate, the −15.1% to +60.1% advantage range and the 2.5-point / 2.1% value of the 0.47 factor; and the $234.62 daily-wage break-even for a fully exempt 15-day aguinaldo. The efficiency model assumes a 30% corporate ISR rate, that the despensa sits within both the ISR and IMSS caps, and — in the second table only — an employer social-contribution rate of 25% of the contribution base, which is an illustrative assumption rather than a statutory rate: yours depends on your riesgo de trabajo class, wage levels and the cesantía phase-in.
