Mexican Withholding Tax: employees’ Income Tax

First, let’s begin with the income tax employees must pay for their salary. 

Indeed, the law requires that employers deduct a proportional amount of income tax contributions from their employees’ paychecks. Then the employer must submit this amount to the government each month. Hence, the term Mexican withholding tax. 

So, let’s get legal. Article 96 of Mexico’s Federal Income Tax Law, or Ley del Impuesto Sobre La Renta (LISR), explicitly stipulates that whoever pays a salary to an employee is obliged to withhold and pay a proportion of that salary. These payments are considered provisional and will be credited against the employee’s annual tax payment.

Retentions are made according to the following table. Retentions are made according to the following table. While Mexican tax authorities update this table annually, you don´t have to worry. Bookmark this article, and you can just come back and check it; we update it every time it changes.

XI $375,975.62 Onwards $117,912.32 35.00%

Ok but how do you calculate it? Indeed, it’s pretty easy. All you need to do is:

  1. Firstly, check the level of income where the salary ranks (the salary will be between the lower limit and the higher limit).
  2. Secondly, subtract the lower limit from the salary. The difference obtained as a result is called a surplus.
  3. Thirdly, apply the salary’s income level tax to the surplus. As a result, you obtain what we call surplus taxes.
  4. Lastly, you add the fixed fee according to the income level to the surplus taxes, and you get the Mexican withholding tax for that month.

So, let’s do it step-by-step.

Mexican Withholding Tax Calculation Example

So let’s do a calculation example. Imagine that you start your business in Mexico and hire your first employee, a talented manager named Jorge. As a result of your negotiations, you offer him a monthly gross salary of MXN 18,000 in exchange for his services. He tells you it doesn’t sound bad, but he would like to know how much money will go into his pocket. Since you bookmarked this article in your browser, you tell him that you will get back to him with his net salary.

So, let’s get to it. 

Firstly, we need to locate Jorge’s Income Level in the Income Tax for Individuals Table. We can find $18,000 in the range of Income Level VI between $15,487.72 and $31,236.49.

Income LevelLower LimitHigher LimitFixed FeeSurplus Tax Rate

Finally, we have all the information we need to make Jorge’s Mexican withholding tax calculation. We know that, because of his level of income, we will need to withhold a fixed fee of $1,640.18. And, we also know that he will have to withhold 21.36% of Jorge’s surplus. So, secondly, let’s calculate that.

Income (-) Lower Limit (=) Surplus
$ 18,000.00 $ (15,487.72) $ 2,512.28

We are almost done calculating Jorge’s Mexican withholding tax. The next step would be applying the tax rate, according to Jorge’s income level, to the surplus.

(=) Surplus(x) Tax Rate(=) Surplus Taxes
$ 2,512.28 21.36% $ 536.62

Lastly, all we have to do is to add Jorge’s income level fixed fee to his surplus taxes. 

(=) Surplus Taxes(+) Fixed Fee(=) Withholding Tax
$ 536.62 $ 1,640.18 $ 2,176.80

In the following table, you can see examples of different income levels.

(-) Lower Limit$746.05$12,935.83$15,487.72
(=) Surplus9,253.952,064.174,512.28
(x) Tax Rate6.40%17.92%21.36%
(=) Surplus Taxes$592.25$369.90$963.82
(+) Fixed Fee$14.32$1,182.88$1,640.18
(=) Taxes to Pay$606.57$1,552.78$2,604.00

Employment Subsidy in Mexican Withholding Tax

Additionally, in Mexico, the government grants a tax benefit to employees whose income is categorized as low. Indeed, it benefits them through their employers by lowering the Mexican withholding tax. Moreover, in some cases, employees can even get a tax refund.

So, let’s see how this works.

First, similarly to the income tax rates, there is a table categorizing different income levels between a lower limit and a higher limit.

Mexican Employment Subsidy Table 2022

Income Level Lower Limit Higher Limit Employment Subsidy
I $0.01 $1,768.96 $407.02
II $1,768.97 $2,653.38 $406.83
III $2,653.39 $3,472.84 $406.62
IV $3,472.85 $3,537.87 $392.77
V $3,537.88 $4,446.15 $382.46
VI $4,446.16 $4,717.18 $354.23
VII $4,717.19 $5,335.42 $324.87
VIII $5,335.43 $6,224.67 $294.63
IX $6,224.68 $7,113.90 $253.54
X $7,113.91 $7,382.33 $217.61
XI $7,382.34 Onwards $0.00

Great. So, how do we calculate it? Let’s do an example then.

Mexican Employment Subsidy Calculation Example

Ok, Jorge was a manager, so we paid him MXN $18,000, which is a good salary by Mexican standards. Meanwhile, let’s think about Raul, an employee that will help us with office cleaning. Specifically, we offer Raul a monthly salary of MX $5,500.

Firstly, we need to calculate the amount of Mexican withholding tax we will be retaining. Since we already know how to do this, I will just summarize that part in the following table.

Raul's Monthly Income $5,500
Income LevelII
(-) Lower Limit$746.05
(=) Surplus$4,754
(x) Tax Rate6.40%
(=) Surplus Taxes$304
(+) Fixed Fee$294.63
(=) Taxes to Pay$598.88

Now that we know the amount of Mexican withholding tax we should retain for Raul let’s calculate how much subsidy he gets from the government. 

First, we need to locate his salary in the employment subsidy table, so we know which income level it’s categorized. 

Income LevelLower LimitHigher LimitFixed Fee

So, because of the level of income that Raul receives, he gets a subsidy of $294.63, now all we have to do is subtract that amount from his income tax calculation. 

Taxes to Pay(-) Employment SubsidyWithholding tax
$ 598.88 $ (294.63) $ 304.25

In conclusion, we know that the Mexican withholding tax we need to retain for Raul is $304.25, instead of the $598.88 we would have withheld if there was no subsidy. 

Since this amount is positive, we need to retain it and pass it over to the tax authorities. Whereas if this amount would be negative, he would get a tax refund. 


So, as discussed, Mexican withholding tax is the amount that the employee has to pay for his income. However, it is the company’s obligation to retain that tax payment from his paycheck and pass it over to the Mexican tax authorities.
