After registration
Getting a RUC is the beginning. Keeping it properly managed is what matters.
The Registro Único de Contribuyentes (RUC)
identifies individuals and companies within Paraguay's tax
system and records the taxpayer's relevant information and
obligations. Once active, it should not be treated as just
another administrative number.
Correctly registered economic activity.
Tax obligations properly configured.
Invoicing through the appropriate system.
Returns filed within the applicable deadlines.
Accounting and supporting documents that can be explained
and reconstructed when needed.
Direct answer
What is a RUC in Paraguay and what is it used for?
The RUC is Paraguay's taxpayer register. It identifies a taxpayer before the tax administration and links that person or entity with the tax obligations that apply to their activity.
02
Companies
EAS, SA and other legal entities require their own taxpayer registration so they can comply with the obligations associated with their business activity.
03
Subsequent changes
Address, economic activity, establishments, representation and other registered information may need to be updated when the taxpayer's actual circumstances change.
Compliance without chaos
You understand what is happening. We coordinate what needs to be done.
Our goal is not to send you forms you cannot understand. You should know which obligation exists, what has been filed, what needs to be paid and what comes next.
RUC registration and updates
We coordinate registration or amendments and review whether the activity, address and tax obligations reflect the taxpayer's real situation.
Tax configuration
We review which taxes, regimes and obligations may apply according to the activity and type of taxpayer.
Accounting
We coordinate accounting records and the supporting documentation needed for the activity to remain organised and defensible.
Tax filings
We monitor the periodic obligations applicable to the taxpayer and coordinate filing according to the relevant tax calendar.
Electronic invoicing
We review the invoicing system that applies and coordinate adaptation to SIFEN, e-Kuatia or e-Kuatia'i where required.
Ongoing follow-up
We maintain a clear workflow for documents, deadlines and next steps so compliance does not depend on remembering each obligation yourself.
An important distinction:
not every taxpayer has the same obligations. An individual,
an EAS, an SA, a professional activity, a trading company or an
investment structure may require different configurations.
We review the situation first and determine what actually needs
to be managed.
Electronic invoicing
Paraguay is moving toward an increasingly electronic invoicing system.
Paraguay's National Integrated Electronic Invoicing System —SIFEN— continues to expand. Electronic invoicing should therefore be considered when a new company starts operating, rather than being treated as something to fix months later.
New legal entities.
Since 1 April 2025, newly registered legal entities in the
RUC may only issue their tax documents electronically through
the systems enabled by the DNIT, subject to the exceptions
established in the applicable rules.
Progressive implementation.
The DNIT continues to expand compulsory electronic invoicing
to additional groups of taxpayers.
e-Kuatia'i.
The DNIT provides a free electronic invoicing solution aimed
at small taxpayers with low document volumes who meet the
system's requirements.
Corporate taxation
The tax rates may look simple. Compliance still requires order.
A comparatively straightforward tax system does not mean that obligations disappear. The activity, tax regime and transactions determine which taxes and filings apply to each taxpayer.
10%
General IRE
The General Corporate Income Tax regime applies a 10% rate to net taxable income.
10%
IRE SIMPLE
The SIMPLE regime also applies a 10% rate, although its eligibility and tax calculation rules differ from the General regime.
10%
General VAT rate
Paraguay uses 10% as the general VAT rate, while certain transactions and categories may be subject to different treatment.
≠
RUC ≠ tax residency
Being registered as a Paraguayan taxpayer does not, by itself, determine an individual's international tax residency.
An essential distinction
Having a RUC in Paraguay does not automatically make you a Paraguayan tax resident.
RUC
The RUC identifies a taxpayer before the DNIT and records information and obligations related to that taxpayer's economic activity in Paraguay.
Tax residency
Tax residency is a separate issue that must be analysed under the applicable tax rules and, in an international relocation, also in relation to the country being left.
How we work
From scattered tax administration to a system you can control.
STEP 01
We review your situation
Individual or company, business activity, current RUC, obligations, invoicing and available documentation.
STEP 02
We establish the workflow
We define which documents need to be sent, when they are needed, how they should be provided and which obligations need to be monitored.
STEP 03
We execute
We coordinate accounting, tax filings, invoicing and administrative obligations according to the agreed scope.
STEP 04
You retain visibility
You know what has been filed, what requires attention and what comes next for the operation.
Less uncertainty
Peace of mind comes from knowing what is actually happening.
A common problem with outsourced accounting is not simply that a filing may be late. It is that the business owner does not know what is being done, which documents are missing or whether an obligation has been overlooked.
One point of coordination.
You do not have to reconstruct each issue between several
different professionals.
Organised documentation.
This makes it easier to respond when banks, counterparties
or compliance teams request supporting information.
Continuity.
Your company does not need to start from zero whenever a new
obligation or administrative requirement appears.
Applied experience
Compliance situations and international projects we have worked on.
The cases are anonymised. Some projects require only a personal RUC; others combine company formation, accounting, residency and international tax coordination.

Local accounting without losing sight of the international picture.

Local coordination
We coordinate accounting and administrative execution in Paraguay so the client does not have to manage each obligation in isolation.
International tax perspective
Where an issue extends beyond Paraguayan accounting and affects tax residency or an international structure, we identify it and analyse it at the appropriate level.

Frequently asked questions
Common questions about RUC and accounting in Paraguay.
What is a RUC in Paraguay?
The Registro Único de Contribuyentes is Paraguay's taxpayer register. It is used by the DNIT to identify taxpayers and record general information and tax obligations associated with them.
Does a company in Paraguay need its own RUC?
Paraguayan legal entities carrying on activities within the tax system require their corresponding taxpayer registration. A company's RUC is separate from the personal RUC of its shareholders.
How is a RUC registered in Paraguay?
The DNIT provides electronic procedures for RUC registration, updates and taxpayer administration through its online tax systems, including Marangatu.
Does having a RUC make me a tax resident of Paraguay?
No. A RUC and tax residency are different concepts. The RUC identifies a taxpayer within Paraguay's tax system, while tax residency requires a separate analysis and may also involve the laws of other countries.
Does a newly incorporated Paraguayan company need electronic invoicing?
Since 1 April 2025, newly registered legal entities in the RUC may only issue their tax documents electronically through the systems authorised by the DNIT, subject to the exceptions specifically established by the applicable regulations.
What is the difference between e-Kuatia and e-Kuatia'i?
Both form part of Paraguay's electronic invoicing ecosystem. e-Kuatia'i is a free DNIT solution aimed particularly at small taxpayers with low electronic-document volumes who meet its eligibility requirements, while other taxpayers use the corresponding SIFEN solutions.
What corporate income tax rate applies in Paraguay?
As a general reference, both the General IRE regime and the SIMPLE regime apply a 10% rate. The applicable regime and calculation depend on the taxpayer's circumstances and business activity.
Do I still need accounting if my company has little or no activity?
Limited activity does not automatically eliminate a company's tax and administrative obligations. Once registered, the company should identify which filings, records and duties remain applicable under its RUC and tax regime.
Can Paraguayan accounting be managed while I live abroad?
Much of the accounting and document workflow can be coordinated remotely. The key is to establish a clear system for invoices, supporting documents, questions, deadlines and local tax obligations.
Does N30 Paraguay provide accounting after company formation?
N30 Paraguay can coordinate ongoing accounting and tax compliance after incorporation so the company is not simply created and abandoned, but continues to meet its obligations according to the agreed scope of service.
