How to Register a SAS Company in Paraguay

What Is a SAS Company?

The Sociedad por Acciones Simplificada (SAS) is Paraguay’s simplified stock company structure, introduced to make business formation faster and more accessible. It is the most popular entity type for foreign entrepreneurs setting up in Paraguay thanks to its flexibility, low requirements, and straightforward process.

Think of it as the Paraguayan equivalent of a US LLC or a UK Ltd — a limited liability entity that protects your personal assets while giving you full operational control.

In this comprehensive guide, we cover everything you need to know about registering a SAS in Paraguay — from comparing entity types and understanding requirements, to a week-by-week timeline, complete cost breakdown, and the ongoing compliance you need to maintain.

SAS vs. SRL vs. SA: Which Business Entity Is Right for You?

Before committing to a SAS, it is worth understanding how it compares to the other main business entity types available in Paraguay:

When to Choose Each Entity

Choose SAS if you are:

A solo entrepreneur or small team
Setting up a business as a foreigner
Looking for the fastest, cheapest formation
Running a service-based or digital business
Want maximum flexibility with minimal bureaucracy

Choose SRL if you are:

Forming a partnership with 2-25 partners
Operating a family business
Working in a sector where SRL is traditional (some professional services)

Choose SA if you are:

Planning to raise capital from multiple investors
Building a large company with complex governance needs
Operating in a regulated sector that requires an SA structure (banking, insurance)

For the vast majority of foreign entrepreneurs, the SAS is the best choice. It combines simplicity, flexibility, and low cost in a way that neither the SRL nor the SA can match.

Requirements for Foreigners

To register a SAS as a foreign national, you need:

Cedula — Your Paraguayan ID card, obtained through the residency process. See what a cedula is
RUC — Your tax identification number. Read our RUC guide
Physical address in Paraguay — for the company’s registered office. A virtual address from MyPyMail satisfies this requirement
Proof of address — utility bill or virtual address documentation
Passport — original and notarized copy

Note: You need residency first (at minimum temporary residency) to obtain the cedula and RUC required for company formation.

Pre-Formation Checklist

Before starting the company registration process, ensure you have completed these prerequisites:

Prerequisite	Status Needed	How to Obtain
Temporary or permanent residency	Approved	Immigration lawyer + Migraciones
Cedula (Paraguayan ID)	In hand	Issued after residency approval
Personal RUC (tax ID)	Registered	SET office or online portal
Physical/virtual address	Active	MyPyMail virtual address or lease
Paraguayan phone number	Active	Tigo, Personal, or Claro SIM card
Local bank account (personal)	Open	Any major bank (Itau, Continental, BBVA)
Immigration lawyer	Engaged	Referrals from expat community
Business lawyer (abogado)	Engaged	May be the same or different from immigration lawyer

Step-by-Step Registration Process

Step 1: Choose Your Company Name

Your company name must be unique and not already registered in Paraguay. You can check availability through the Registro Publico de Comercio or have your lawyer verify it. The name must include “SAS” or “Sociedad por Acciones Simplificada” in the title.

Name guidelines:

Must not be identical or confusingly similar to an existing registered company
Cannot use names reserved by the state or protected trademarks
Must include the “SAS” designation
Can be in any language, but Spanish is recommended for practical reasons
Short, memorable names are easier for banking, invoicing, and daily operations

Tip: Have your lawyer check 2-3 alternative names in case your first choice is taken. The name check process takes 1-3 business days.

Step 2: Draft the Articles of Incorporation

The estatutos sociales (articles of incorporation) define your company’s:

Company name and purpose (objeto social)
Registered address (domicilio legal)
Capital structure and share distribution
Management structure (who serves as administrator)
Duration of the company (can be indefinite)
Rules for shareholder meetings and decisions
Profit distribution rules
Dissolution procedures

A Paraguayan lawyer drafts these documents. Cost for legal drafting is typically $500-1,500 USD depending on complexity.

Important decisions to make during drafting:

Company purpose: Should be broad enough to cover all intended activities without being so vague that it raises questions. Your lawyer can advise on standard objeto social language
Capital amount: While there is no legal minimum, a practical amount (e.g., 10,000,000 PYG / ~$1,300 USD) is recommended. Banks may consider your stated capital when evaluating account applications
Administrator designation: You can name yourself as the sole administrator or designate someone else. Foreign administrators are permitted
Fiscal year: Typically aligns with the calendar year (January-December) unless you have a specific reason for a different period

Step 3: Notarize Documents

Your articles of incorporation and related documents must be notarized by a Paraguayan public notary (escribano publico). This typically costs 100,000-300,000 guarani ($13-40 USD).

The notary verifies:

Identity of the incorporator(s)
Authenticity of documents
Legal capacity of the signatories
Compliance with formal legal requirements

Step 4: Register Through SUAE

Paraguay’s Sistema Unificado de Apertura y Cierre de Empresas (SUAE) is the one-stop system for business registration. Through SUAE, you simultaneously:

Register with the Registro Publico de Comercio (Commercial Registry)
Obtain your company’s RUC (tax ID)
Register with the Ministry of Labor (if you will have employees)
Register with the Social Security Institute (IPS) (if applicable)

The SUAE process can be initiated online, though some steps still require in-person visits or lawyer representation.

SUAE submission requires:

Notarized articles of incorporation
Cedula copies of all shareholders/administrators
Personal RUC of all shareholders
Proof of registered address (virtual address documentation or utility bill)
Completed SUAE application forms
Payment of registration fees

Step 5: Publish Legal Notice

A legal notice of your company’s formation must be published in a registered newspaper. This is a formality that costs approximately 200,000-400,000 guarani ($25-55 USD).

The publication must appear in a nationally circulated newspaper and includes:

Company name
Registered address
Capital amount
Names of shareholders and administrators
Date of incorporation

Your lawyer handles the placement and provides you with proof of publication.

Step 6: Receive Registration Confirmation

After SUAE processes your application, you receive:

Certificate of incorporation from the Registro Publico de Comercio
Company RUC number from SET
Official company stamp (many businesses in Paraguay use a rubber stamp for documents)
Commercial registration number

These documents collectively prove your company’s legal existence and allow you to operate.

Step 7: Set Up Electronic Invoicing

Paraguay requires businesses to use electronic invoicing (facturacion electronica). You will need to:

Register for electronic invoicing through SET’s online system (SIFEN)
Obtain a digital certificate
Choose invoicing software compatible with SET’s system
Issue your first electronic invoice to activate the system

Your accountant typically handles this setup as part of their onboarding process.

Step 8: Open a Business Bank Account

With your company registered and RUC obtained, you can open a corporate bank account. See our guide on banking in Paraguay for the best banks for foreigners.

Documents needed for corporate account:

Company certificate of incorporation
Company RUC certificate
Articles of incorporation (notarized copy)
Proof of published legal notice
Administrator’s cedula and personal RUC
Company stamp
Proof of registered address
Board resolution authorizing account opening (for multi-shareholder companies)

Best banks for foreign-owned businesses:

Bank	Pros	Cons
Banco Itau	International experience, good online banking	Stricter compliance requirements
Banco Continental	Largest bank, wide network	Bureaucratic processes
BBVA Paraguay	International brand, good services	Higher minimum balances
Banco Atlas	More flexible with foreigners	Smaller network
Sudameris	Growing digital services	Less international experience

Tip: Start the bank account process as soon as you have your company registration. Banking is often the longest single step in the entire process. Some banks take 1-2 weeks just for internal compliance review before opening the account.

Step 9: Obtain Municipal License

Depending on your business activity and location, you may need a patente municipal (municipal business license) from the local municipality.

For Asuncion municipality:

Application form from the Municipalidad de Asuncion
Company registration documents
Proof of registered address
Description of business activities
Payment of municipal license fee (varies by activity and projected revenue)

The patente municipal is renewed annually and the cost is based on your declared revenue and business category.

Tax Registration and RUC for Your SAS

Company RUC Registration

Your company’s RUC is typically obtained through SUAE as part of the registration process. However, you need to ensure proper categorization:

RUC category for a standard SAS:

IRACIS (Impuesto a la Renta de las Actividades Comerciales, Industriales y de Servicios) — 10% on net profits
IVA (Impuesto al Valor Agregado) — 10% on goods and services
Withholding agent — if you pay contractors or employees

For detailed information on the RUC registration process, see our dedicated guide.

Tax Obligations for a SAS

Your SAS company will be subject to:

IRACIS (corporate income tax): 10% on net profits from Paraguayan-sourced income
IVA (value added tax): 10% on goods and services
Dividend tax: 5% when distributing profits to shareholders

Remember, Paraguay’s territorial tax system means income from foreign sources may be exempt from corporate tax. This is one of the primary reasons foreign entrepreneurs choose Paraguay for their business base.

Monthly Tax Filing Calendar

Filing	Deadline	Form
IVA declaration	15th of following month	Formulario 120
Withholding tax declaration	15th of following month	Various forms
Electronic invoice reconciliation	Ongoing	Through SIFEN
IPS contributions (if employees)	15th of following month	IPS forms

Annual Tax Filing Calendar

Filing	Deadline	Form
IRACIS annual declaration	April (for previous fiscal year)	Formulario 101
Financial statements	With IRACIS filing	Balance sheet, income statement
Beneficial ownership declaration	Annual update	SET form

Using a Virtual Address for Your SAS

Every registered company in Paraguay needs a physical address for its registered office. A virtual address from MyPyMail provides:

A legitimate Asuncion street address for your official registration
Receipt and scanning of all company correspondence
A professional business presence
Mail forwarding when physical documents are needed
Acceptance of government correspondence from SET, Migraciones, and municipalities
Secure storage of original documents

Learn more about using a virtual address for business registration.

Why a Virtual Address Makes Sense for Your SAS

Need	Virtual Address Solution
Registered office requirement	Real Asuncion street address accepted by Registro Publico
SET correspondence	Tax notices received, scanned, and forwarded immediately
Bank correspondence	Card deliveries, statements, and compliance letters handled
Municipal license address	Accepted for patente municipal applications
Professional image	Real street address on invoices, contracts, and website
Cost vs. office lease	$30-80/month vs. $300-800/month for physical office

For businesses that do not need a physical workspace, a business address from MyPyMail is the most cost-effective and practical solution.

Annual Compliance Requirements

Keeping your SAS in good standing requires ongoing attention to several compliance obligations:

Mandatory Annual Tasks

Task	Deadline	Consequence of Non-Compliance
IRACIS annual filing	April	Fines, potential RUC suspension
IVA monthly declarations (12 per year)	15th of each month	Fines per late filing
Financial statement preparation	With annual filing	Required for tax compliance
Municipal license renewal	Varies by municipality	Business cannot legally operate
Beneficial ownership update	Annual	Fines from SET
Electronic invoicing compliance	Ongoing	Inability to issue valid invoices
IPS contributions (if employees)	Monthly	Penalties, potential legal action

Record Keeping Requirements

Maintain these records for at least 5 years:

All issued and received invoices (electronic records)
Bank statements
Contracts with clients and suppliers
Employee records (if applicable)
Tax filing receipts and confirmations
Board resolutions and shareholder meeting minutes
Correspondence with SET and other government agencies

Common Mistakes to Avoid

Mistake 1: Skipping the Lawyer

While technically possible to self-register, the cost of mistakes far exceeds legal fees. A good business lawyer in Paraguay charges $500-1,500 for the entire formation process — an investment that prevents errors that could cost thousands to fix.

Mistake 2: Choosing the Wrong Entity Type

Make sure SAS is right for your situation — discuss alternatives with your lawyer. Some specific situations may favor an SRL (if you have a fixed partnership structure) or require an SA (if you are in a regulated sector).

Mistake 3: Ignoring Ongoing Compliance

Annual filings and tax returns are mandatory even for companies with no revenue. A dormant SAS that does not file can accumulate fines, have its RUC suspended, and create headaches when you eventually want to close or reactivate it.

Mistake 4: Not Planning for Banking

Start the bank account process early — it can be the longest step. Have your documentation ready to submit the day you receive your company registration.

Mistake 5: Undercapitalizing on Paper

While there is no legal minimum capital, listing a very small amount (e.g., 1,000,000 PYG / ~$130) can raise red flags with banks and potential business partners. A capital of 10,000,000-50,000,000 PYG ($1,300-6,500 USD) is more credible.

Mistake 6: Not Separating Personal and Business Finances

From day one, maintain separate personal and business bank accounts. Co-mingling funds weakens limited liability protection and creates accounting nightmares.

Mistake 7: Forgetting About Electronic Invoicing

Paraguay mandates electronic invoicing (facturacion electronica) for IRACIS taxpayers. Setting this up requires a digital certificate, compatible software, and registration with SET’s SIFEN system. Do not wait until your first sale to set this up.

Mistake 8: Neglecting the Municipal License

Many entrepreneurs focus on national registration and forget the municipal patente. Operating without a valid municipal license can result in fines and legal complications.

Mistake 9: Not Having a Contingency Plan for Banking Issues

Paraguayan banks can be unpredictable with foreign-owned businesses. If your first-choice bank declines or delays, have backup banks identified. Your lawyer may have relationships that can facilitate introductions.

Mistake 10: DIY Accounting

Paraguayan tax compliance requires knowledge of local regulations, forms, and filing systems. Even if you are financially savvy, hiring a local contador (starting at $150/month) is essential. The cost is minimal compared to the risk of errors.

After Formation: Growing Your Business in Paraguay

Hiring Employees

If your SAS grows to the point of hiring:

Minimum wage: Approximately $380 USD/month (2024 rate, adjusted annually)
Employer contributions: IPS (social security) at ~16.5% of salary
Employee contributions: ~9% of salary (withheld by employer)
Annual bonus (aguinaldo): One month’s salary, paid in December
Vacation: 12 working days per year (first 5 years), increasing with seniority
Severance: Required for unjustified termination

Scaling Operations

As your business grows, consider:

Upgrading your virtual address to a business address plan with enhanced services
Moving from electronic-only invoicing to a full accounting system
Engaging a more comprehensive accounting firm
Establishing relationships with multiple banks
Registering intellectual property (trademarks) in Paraguay
