## What is Rule 12.3.2?
On August 2026, Mexico's SAT introduced **Rule 12.3.2**, which mandates that **individuals (personas físicas)** who:
- sell goods, \n- provide services, \n- rent accommodation or allow temporary use of goods **through digital platforms, apps, or similar** must file a special notice updating their economic activities and tax obligations.

This update is made via **Trámite 71/CFF**, "Aviso de actualización de actividades económicas y obligaciones", indicating specifically which platform-based activities are carried out. ([wwwmatnp.sat.gob.mx](https://wwwmatnp.sat.gob.mx/articulo/66233/regla-12.3.2?utm_source=openai))

## Who is affected & what platforms count?
- **Digital nomads** who monetize through platforms like Airbnb, Uber, TaskRabbit, Etsy, or freelancing marketplaces.
- Sellers using e-commerce channels or “rideshare & delivery” apps.
- Providers of lodging, rental, temporary use of assets via platforms.
Even if income is passive or from multiple platforms, the rule applies to any person engaging in those activities. Businesses (entities) may have different obligations, but this is specifically about individuals. ([wwwmatnp.sat.gob.mx](https://wwwmatnp.sat.gob.mx/articulo/66233/regla-12.3.2?utm_source=openai))

## What you must do & when
- File the **Trámite 71/CFF** notice and update the **Anexo 1-A, Movimiento de actividades económicas y obligaciones**.
- Detail each economic activity carried via platforms.
There's no explicit deadline in the text, but it’s part of regular updates—best done as soon as one starts or uses platforms in taxable activities to avoid penalties.

## Tax Planning & Compliance Tips
- **Determine your residency**: whether you're in Mexico for tax residence purposes (183 days rule, etc.), as obligations differ.
- **Keep income records by platform**: invoices, payouts, dates—SAT may cross-check with data shared by platforms.
- **Expense documentation**: only certain expenses are deductible; digital nomads should track what’s allowable under Mexican ISR and IVA regimes.
- **Use electronic invoicing** (CFDI) if required; many platforms demand issuance of CFDIs.

## Example Scenario
Ana, a digital nomad from Spain, is staying in Mexico for 4 months. She lists her apartment on Airbnb, does freelance graphic design via Upwork, and drives for a ride-sharing platform. Under Rule 12.3.2, she must:
a) File the notice updating that she uses platforms for lodging, services and transport.
b) Potentially register for ISR (income tax) and IVA obligations depending on whether she's considered resident or not.
c) Track her platform income and issue CFDIs if required.

## When non-compliance can bite & risks to consider
- **Penalties**: failure to file the notice can lead to fines or an audit.
- **Cross-platform reporting**: if the platforms themselves report or share data, mismatch can trigger liabilities.
- **Double taxation & withholding**: foreigners or nonresidents must understand withholding rules under treaties if applicable.
