A primary-source research report by Start-Ops Mexico. Methodology and live calculator: mexico-labor-cost-calculator.
The salary number a US company sees on a Mexican recruiter’s spreadsheet, when properly loaded with employer-side mandatory contributions and accruals, is 30 to 34 percent below the fully-loaded cost of employment in 2026 — rising to 40 to 44 percent once you include the 10% PTU profit share. That gap — between gross salary and total cost — is the most consequential, and the most consistently misquoted, number in the entire nearshoring conversation.
This report calculates, state by state, what it actually costs a US company to employ a Mexican worker in 2026. We use the values in force as of the publication date: the UMA (Unidad de Medida y Actualización) at $117.31 MXN daily, up 3.75% year-over-year; the general minimum wage at $315.04 MXN/day (a monthly floor of $9,451) and the Frontera Norte minimum wage at $440.87 MXN/day ($13,226 monthly), both in force since January 1; and the 2026 column of the eight-year graduated employer pension contribution (Cesantía y Vejez) that ratchets up each year until 2030.
Three findings matter most. First, for a senior software developer earning $60,000 MXN/month in 2026, the all-in employer cost ranges from $78,235 MXN/month in the four lowest-tax states (Chiapas, Colima, Guerrero, Morelos at 2.00% ISN) to $79,652 MXN/month in Baja California at 4.25% ISN — a burden of 30.4% to 32.8% on top of gross salary, rising to 40.4% to 42.8% with PTU. Second, the constitutional reform passed in March 2026 that reduces the standard workweek from 48 to 40 hours by 2030 will add an effective 16 to 17 percent to per-employee labor costs if salaries hold flat, the single largest forward-looking cost movement on the horizon. Third, the most-cited mistake we see in US buyers’ models is using the 2030 final-state CV rate instead of the 2026 phased rate, which overstates the employer pension cost by roughly 58% at the top tier.
The numbers below are computed from primary sources — DOF publications, the LSS, the LFT, INFONAVIT’s authorizing law, and each state’s Ley de Hacienda. All four representative roles are modeled at IMSS Risk Class 2 (1.13%, the default for office and most service work), with the CV employer rate applied at the correct UMA tier for each worker’s SBC, and federal contributions capped at the 25-UMA SBC ceiling per LSS Art. 28. Journalists, analysts, and HR teams should treat this report as a citable baseline for 2026.
“The gap between Mexican gross salary and the fully-loaded cost of employment is 30 to 34 percent before PTU — or 40 to 44 percent with the 10% profit share. US buyers who model the salary number alone are off by tens of thousands of dollars per hire per year.”
“By 2030, hiring five employees in Mexico will cost what hiring six costs today — the 40-hour workweek reform is the largest forward-looking cost movement nearshoring buyers aren’t pricing in.”
“Baja California’s payroll tax is more than double Chiapas’s. For a 50-person team at the senior-developer level, that’s roughly $850,000 MXN per year in employer tax alone.”
“The UMA went up 3.75 percent in 2026. Anyone who budgeted Mexican labor in 2025 needs to re-budget — every IMSS contribution is indexed to it.”
“The graduated pension contribution still has four more annual increases ahead of it. The 2026 number is not the final number.”
“Mexico’s general minimum wage rose 26.6 percent in two years to $315.04 MXN/day — a monthly floor of $9,451 MXN. The arbitrage story is real, but it is no longer the ‘cheap labor’ story of a decade ago.”
The four roles below are representative of the hires US companies actually make in Mexico in 2026. We compute the all-in monthly employer cost for each, using the national-average ISN (Impuesto Sobre Nóminas — state payroll tax) of 3.00%, a Risk Class 2 IMSS premium (1.13%, the default for office and most service work), and the 2026 CV (Cesantía y Vejez) phase rates from the eight-year DOF 16-12-2020 transitional schedule applied at the correct tier for each worker’s SBC.
The Factory Worker column uses a gross salary of $9,500 MXN/month — just above the 2026 general minimum wage monthly floor of $9,451 MXN ($315.04/day × 30). For roles in Frontera Norte (the border zone), the minimum is $13,226 MXN/month. Operations Manager federal contributions are capped at the 25-UMA SBC ceiling ($87,983 MXN/month) per LSS Art. 28, which is why the burden percentage flattens at the top of the salary distribution.
All figures are monthly, in MXN, with USD equivalents at $17.50/USD (see Methodology for FX note). Employer contributions are calculated against the SBC (Salario Base de Cotización), which integrates the daily salary with 15 days of aguinaldo (LFT Art. 87) and the 25% prima vacacional on 12 days of vacation (LFT Art. 80, Art. 76) for an integration factor of approximately 1.0493 in year one.
| Component | Factory Worker | Junior Developer | Senior Developer | Operations Manager |
|---|---|---|---|---|
| Gross monthly salary (MXN) | $9,500 | $30,000 | $60,000 | $90,000 |
| Gross monthly salary (USD) | $543 | $1,714 | $3,429 | $5,143 |
| IMSS employer (Class 2, incl. Retiro 2%) | $1,479 | $3,350 | $6,098 | $8,283 |
| INFONAVIT (5% of SBC, 25-UMA cap) | $498 | $1,574 | $3,148 | $4,399 |
| CV (2026 phase, tier-based) | $478 | $2,365 | $4,730 | $6,610 |
| ISN (3.00% national avg) | $299 | $944 | $1,889 | $2,833 |
| Aguinaldo accrual (15 days) | $396 | $1,250 | $2,500 | $3,750 |
| Prima vacacional accrual | $79 | $250 | $500 | $750 |
| Total monthly cost (MXN) | $12,729 | $39,733 | $78,865 | $116,625 |
| Total monthly cost (USD) | $727 | $2,270 | $4,506 | $6,664 |
| Burden on gross salary | 34.0% | 32.4% | 31.4% | 29.6% |
| Burden including PTU (10%) | 44.0% | 42.4% | 41.4% | 39.6% |
Three notes on this table. First, the IMSS line aggregates eight items defined in LSS Articles 25, 73-74, 106, 107, 147, 168, and 211: cuota fija (20.4% of UMA daily, a flat amount of $717.94/month regardless of salary), excedente (1.10% of SBC above 3 UMA), prestaciones en dinero (0.70%), gastos médicos pensionados (1.05%), invalidez y vida (1.75%), guarderías (1.00%), risk premium (1.13% at Class 2), and Retiro (2.00% of SBC). For the Factory Worker, the cuota fija dominates and the excedente is zero because the SBC ($9,968/month, or 2.83 UMA daily) does not exceed the 3 UMA threshold.
Second, the CV (Cesantía y Vejez) rate is tier-based per DOF 16-12-2020 Cuarto Transitorio. For 2026, the employer rate is 4.799% on SBC in the 2.51–3.00 UMA tier (Factory Worker at $9,500) and 7.513% at 4.01+ UMA (all three office roles, which sit at 8.94, 17.89, and 26.84 UMA respectively). Reports that apply the top-tier 7.513% to a minimum-wage worker overstate the cost; reports that apply the 3.150% floor to higher earners understate it.
Third, PTU (Participación de los Trabajadores en las Utilidades) — the constitutionally-mandated 10% profit share — is a real annualized employer cost but it is paid against profits, not against payroll. Most US buyers exclude it from monthly burden calculations and then are surprised in May of the following year. We show it both ways. The capped version (three months of salary or the company’s three-year PTU average, whichever is higher, per the 2021 outsourcing reform amendment to LFT Art. 127) puts a ceiling on the exposure, but the headline number is 10% of taxable profits attributable to the Mexican entity.
For a senior software developer at $60,000 MXN gross, the realistic 2026 all-in monthly cost is $78,865 MXN excluding PTU at the 3.00% national-average ISN, or roughly $84,865 MXN including PTU accrual at the 10%-of-salary approximation. That’s $4,506 to $4,849 USD per month — still a meaningful arbitrage versus US engineering rates, but materially higher than the $3,429 gross salary number most surveys cite.
The table below shows the 2026 ISN (state payroll tax) for all 32 Mexican federal entities and the resulting total monthly employer cost for a senior software developer at $60,000 MXN gross. The ISN line item is the single largest source of cross-state variance: at the extremes, Baja California’s 4.25% rate is more than double the 2.00% paid in Chiapas, Colima, Guerrero, and Morelos. For a 50-person engineering team at this salary level, the state-level ISN delta alone is approximately $850,000 MXN per year.
ISN rates below are taken from each state’s Ley de Hacienda as in force on the publication date. Rates do change — Mexico City raised its rate from 3.00% to 4.00% on certain payrolls in prior years, and several states have considered increases as part of 2026 budget cycles — so always verify before signing a multi-year lease or hiring plan.
| State | 2026 ISN Rate | Monthly Total Cost (Senior Dev, $60K MXN) | USD Equivalent |
|---|---|---|---|
| Chiapas | 2.00% | $78,235 | $4,471 |
| Colima | 2.00% | $78,235 | $4,471 |
| Guerrero | 2.00% | $78,235 | $4,471 |
| Morelos | 2.00% | $78,235 | $4,471 |
| Tabasco | 2.50% | $78,550 | $4,489 |
| Aguascalientes | 3.00% | $78,865 | $4,506 |
| Campeche | 3.00% | $78,865 | $4,506 |
| Chihuahua | 3.00% | $78,865 | $4,506 |
| Coahuila | 3.00% | $78,865 | $4,506 |
| Durango | 3.00% | $78,865 | $4,506 |
| Estado de México | 3.00% | $78,865 | $4,506 |
| Guanajuato | 3.00% | $78,865 | $4,506 |
| Hidalgo | 3.00% | $78,865 | $4,506 |
| Jalisco | 3.00% | $78,865 | $4,506 |
| Mexico City (CDMX) | 3.00% | $78,865 | $4,506 |
| Michoacán | 3.00% | $78,865 | $4,506 |
| Nayarit | 3.00% | $78,865 | $4,506 |
| Nuevo León | 3.00% | $78,865 | $4,506 |
| Oaxaca | 3.00% | $78,865 | $4,506 |
| Puebla | 3.00% | $78,865 | $4,506 |
| Querétaro | 3.00% | $78,865 | $4,506 |
| San Luis Potosí | 3.00% | $78,865 | $4,506 |
| Sinaloa | 3.00% | $78,865 | $4,506 |
| Sonora | 3.00% | $78,865 | $4,506 |
| Tamaulipas | 3.00% | $78,865 | $4,506 |
| Tlaxcala | 3.00% | $78,865 | $4,506 |
| Veracruz | 3.00% | $78,865 | $4,506 |
| Yucatán | 3.00% | $78,865 | $4,506 |
| Zacatecas | 3.00% | $78,865 | $4,506 |
| Baja California Sur | 4.00% | $79,494 | $4,542 |
| Quintana Roo | 4.00% | $79,494 | $4,542 |
| Baja California | 4.25% | $79,652 | $4,552 |
The most important observation in this table is the flatness of the middle band. Twenty-five of 32 states sit at exactly 3.00% ISN. The action is at the tails: four states at 2.00%, one at 2.50%, two at 4.00%, and Baja California alone at 4.25%. For US companies optimizing for labor tax burden, the four 2.00% states are worth modeling — but each comes with tradeoffs on talent density (Chiapas and Guerrero have thin engineering pools relative to Jalisco or Nuevo León) and on infrastructure that aren’t visible in a payroll spreadsheet.
The other observation: the ISN range, end-to-end, is only $1,417 MXN/month per employee — about 1.8% of total cost. State payroll tax matters at scale, but it is not the dominant cost lever. The dominant levers are the federal IMSS/INFONAVIT contributions, which are constant across states, and the role/salary level itself.
After 200+ scoping conversations with US buyers in the last 18 months, the same five line items show up missing — or misquoted — in their internal models. In order of severity:
1. IMSS Risk Class variation (LSS Art. 73-74). Every Mexican employer is classified into one of five risk classes for occupational accident insurance. The maximum premium ranges from 0.54% of SBC at Class 1 (office work) to 7.59% at Class 5 (mining, heavy industry, construction). Most US sources cite the Class 1 or Class 2 number and treat it as universal. A medical-device manufacturer modeling Class 2 when their CIIU code lands them in Class 4 is understating IMSS by roughly 3.5 percentage points of SBC. What to do: confirm the CIIU classification of the actual work before modeling. This report uses Risk Class 2 (1.13%) for all four representative roles; manufacturing and field operations should be re-modeled at their actual class.
2. The CV (Cesantía y Vejez) graduated table — 2026 vs. 2030, AND the tier matters. The 2020 pension reform (DOF 16-12-2020 Cuarto Transitorio) ratchets employer pension contributions up annually from 2023 to 2030 AND varies the rate by tier of worker SBC. At the top tier (4.01+ UMA), the rate climbs from 4.241% in 2023 to 11.875% in 2030. The 2026 top-tier rate is 7.513%, but a minimum-wage worker in the 2.51–3.00 UMA tier pays only 4.799% — a 36% lower rate. Most US-published “Mexico labor cost” guides cite the 2030 final-state top-tier rate as if it applied universally. What to do: model the year you’re hiring in, identify each worker’s SBC tier in UMA, and price in the trajectory if you’re committing past 2028.
3. PTU (profit sharing — LFT Art. 117-131). Mexican employers distribute 10% of pre-tax profits to employees annually. The 2021 outsourcing reform capped individual PTU at the higher of (a) three months of the employee’s salary or (b) the average PTU the employee received over the previous three years. US buyers routinely omit this from modeling because it doesn’t appear on the monthly payroll line. For a profitable Mexican operation, PTU adds approximately 8 to 10 percent to fully-loaded annual labor cost. What to do: accrue monthly against expected profit and disclose it in your annual budget. Surprise PTU in May is one of the most common ways CFOs lose trust in Mexican operations.
4. Aguinaldo and prima vacacional combined (LFT Art. 87 and Art. 80). Aguinaldo is the mandatory year-end bonus: a minimum of 15 days of salary, paid by December 20. Prima vacacional is a 25% premium on the salary paid during vacation days (12 days minimum in year one, scaling up per LFT Art. 76 to 30 days by year 30 of service). Together these add roughly 5.5% to base salary cost in year one and climb steadily with tenure. What to do: treat both as monthly accruals, not annual surprises. The accrual is also folded into SBC for IMSS/INFONAVIT/CV calculations, so leaving it out understates the federal contribution lines too.
5. State ISN variance — but mostly as a planning input, not a runtime cost. As shown in the state table, ISN ranges from 2.00% to 4.25%. For most US buyers the more relevant question isn’t “what does ISN cost me in State X” but “is ISN a reason to pick State X over State Y.” At a 50-person team at the senior-developer level, the gap between a 2.00% state and Baja California’s 4.25% is roughly $850,000 MXN per year — meaningful, but rarely the deciding factor against talent density, real estate, and proximity to a USMCA border crossing. What to do: model ISN, but don’t let it lead the site-selection decision.
Three indexed inputs to Mexican employer cost moved between 2024 and 2026, and a US company’s 2024 hire is materially more expensive in 2026.
| Year | UMA Daily (MXN) | YoY Change |
|---|---|---|
| 2024 | $108.57 | — |
| 2025 | $113.07 | +4.14% |
| 2026 | $117.31 | +3.75% |
Cumulative 2024→2026: +8.05%. Every contribution line that’s expressed as a percentage of UMA — most importantly the IMSS cuota fija at 20.4% of UMA daily, and the SBC excedente threshold of 3 UMA — climbs with this index. For employees near the minimum wage tier, this is the dominant cost mover.
| Year | General (MXN/day) | Frontera Norte (MXN/day) |
|---|---|---|
| 2024 | $248.93 | $374.89 |
| 2025 | $278.80 | $419.88 |
| 2026 | $315.04 | $440.87 |
The general minimum wage rose from $248.93 in 2024 to $315.04 in 2026 — a 26.6% cumulative increase over two years. Frontera Norte (the border zone) tracks slightly differently and remains roughly 40% above the general rate. For factory and entry-level service work, the minimum wage is the labor cost.
The 2020 reform schedule ratcheted the top-tier (4.01+ UMA) employer rate as follows:
| Year | 4.01+ UMA Tier Rate |
|---|---|
| 2023 | 4.241% |
| 2024 | 5.331% |
| 2025 | 6.422% |
| 2026 | 7.513% |
| 2027 | 8.603% |
| 2028 | 9.694% |
| 2029 | 10.784% |
| 2030 | 11.875% |
For a senior developer at $60,000 MXN/month, the CV contribution alone has risen from roughly $3,160 MXN/month in 2024 to $4,729 MXN/month in 2026 — a $1,569 MXN/month increase per employee, purely from the pension phase-in. Over a 25-person engineering team that’s nearly $471,000 MXN/year in net new employer cost between 2024 and 2026 with no salary change.
The framing for journalists: the 2025 hire who looked like a great deal is, in 2026, between 4% and 7% more expensive at the same salary — entirely from federal indexation and the pension reform schedule. None of this is a discretionary cost.
In March 2026, Mexico approved the constitutional amendment to LFT Art. 61 reducing the standard workweek from 48 hours to 40 hours, phased in gradually through 2030. The first reduction (to 46 hours) takes effect January 1, 2027, with subsequent two-hour annual reductions until the 40-hour week is in force.
The structural cost implication is straightforward and large. A worker producing the same output in 40 hours that previously took 48 hours represents a 20% productivity gain implied by the law. Unless that productivity gain materializes in practice — and across most service and manufacturing settings the evidence is that it partially does, but not fully — the cost shows up somewhere. Three places it can land:
In practice, US-facing operations will mostly see a blend of options 1 and 2, with the realistic effective increase to per-employee fully-loaded labor cost landing in the 16% to 17% range by 2030.
The quotable framing: by 2030, hiring five employees in Mexico will cost what hiring six costs today.
US buyers signing leases or making multi-year nearshoring commitments in 2026 should price the workweek reform into their 2027-2030 cost trajectory. The change is not optional, not negotiable, and the implementation timeline has already begun.

Primary sources (federal):
Primary sources (state ISN): Each state’s Ley de Hacienda (or equivalent fiscal law) as in force on the publication date. Rates verified state-by-state in May 2026.
FX assumption: USD/MXN at $17.50 for USD equivalencies. This is a working planning rate as of May 2026 and not a forecast; for hiring decisions, use the spot rate at the time of contracting.
Calculations: All employer-cost line items are computed using the SBC integration factor for a year-one employee (15 days of aguinaldo + 25% prima vacacional on 12 days of vacation, yielding an integration factor of approximately 1.0493). Risk Class 2 (1.13%) is used as the default IMSS risk premium for all four representative roles; manufacturing and field roles should be re-modeled at their actual CIIU classification. Federal contributions (IMSS, INFONAVIT, CV) are capped at the 25-UMA SBC ceiling ($87,983/month in 2026) per LSS Art. 28 — this binds for the Operations Manager column at $90,000 MXN gross.
Live, updated calculator: This report is computed from the same dataset that powers the Mexico Labor Cost Calculator. The calculator is updated each February when INEGI publishes the new UMA, and annually thereafter as state ISN rates and the CV phase advance.
