Tax Withholdings

From Sales → CFDI → Documents → Withholdings you can issue withholding and payment information documents in compliance with SAT guidelines. These documents are required when you make payments to third parties and must withhold taxes.

Regional availability

Withholding documents are exclusively available for fiscal operations in Mexico and require prior CSD configuration.

Contributor data

1

Contributor type

Indicate whether the withholding recipient is an individual or legal entity, domestic or foreign.

2

RFC or tax identifier

For domestic contributors, enter the RFC. For foreign ones, enter their country's tax identification number.

3

Withholding key

Select the withholding type from the SAT catalog:

  • 01 — Professional services (fees)
  • 02 — Leasing
  • 03 — Stock sales
  • 06 — Interest
  • 14 — Dividends
  • 25 — Foreign payments

Withholding period

Select the month and year for the withholding:

FieldDescription
Start monthPeriod start month
End monthPeriod end (can be the same for monthly withholdings)
Fiscal yearTax year

Tip

For recurring monthly withholdings (like leasing), the start and end months are the same. For annual withholdings, the range covers January through December.

Withholding calculation

1

Base amount

Enter the total payment amount before withholdings. This is the gross amount on which the withholding is calculated.

2

Withheld tax type

Select the taxes to withhold:

  • ISR — Income Tax
  • VAT — Value Added Tax (partial withholding)
  • IEPS — Special Tax on Production and Services
3

Withholding rate

Define the percentage rate. Fenicia automatically calculates:

Withholding = Base x Rate

For example: $10,000 x 10% ISR = $1,000 withholding.

4

Tax detail

You can add multiple withholdings to the same document (ISR + VAT is common for leasing).

International payments

For withholdings to foreign beneficiaries:

1

Select country of residence

Choose the country from the ISO catalog. ISR rates may vary based on double taxation treaties.

2

Foreign tax identifier

Enter the beneficiary's tax ID in their home country.

3

Configure applicable rates

Withholding rates for foreign payments may differ from domestic ones. Check applicable treaties.

Double taxation treaties

Mexico has treaties with over 60 countries that may reduce withholding rates. Verify the applicable treaty before setting the rate.
