Latest Common Questions
10 Essential Questions About TIN in Peru

calendar2/3/2026

Peru operates a sophisticated tax environment managed by the Superintendencia Nacional de Aduanas y de Administración Tributaria (SUNAT). With a standard VAT (IGV) rate of 18% and strict electronic invoicing rules (OSE/SEE), compliance is non-negotiable.

For international businesses, especially following the Legislative Decree 1623 (effective late 2024) regarding digital services, navigating the Peruvian RUC system is essential to avoid penalties and ensure the deductibility of expenses.

Introduction

The backbone of Peru’s fiscal infrastructure is SUNAT. Unlike jurisdictions where a Tax ID is just a number, in Peru, the RUC (Registro Único de Contribuyentes) status dictates whether you can legally issue an invoice or move goods.

For global enterprises, the challenge is verifying the 11-digit RUC to ensure legitimate B2B trade. A critical nuance in Peru is that a partner must not only exist but also be domiciled correctly (“Habido”). Missteps here prevent the use of the “Fiscal Credit” (IGV deduction).

10 Essential Questions About TIN in Mexico

calendar2/3/2026

Mexico operates one of the most sophisticated digital tax administrations in the world, managed by the Servicio de Administración Tributaria (SAT). With the mandatory implementation of CFDI 4.0 (Electronic Invoicing), simply having a Tax ID is no longer enough; the data must match the SAT’s records character-for-character.

For international businesses and digital platforms, complying with Mexican law means navigating the RFC (Registro Federal de Contribuyentes) and avoiding the dreaded “Listas Negras” (Blacklists) of simulated operations.

Introduction

The backbone of Mexico’s fiscal infrastructure is the SAT. Unlike jurisdictions where tax numbers are just for reporting, in Mexico, the RFC is the key to the real-time validation of every transaction.

For global enterprises, the challenge is verifying the 12-character Business RFC to ensure legitimate B2B trade. Missteps here prevent the issuance of valid invoices (CFDI), meaning your customers cannot deduct expenses, and you expose your business to a standard VAT liability of 16%.

10 Essential Questions About TIN in Georgia

calendar2/2/2026

Georgia has established itself as one of the easiest places in the world to do business, with a streamlined tax administration managed by the Revenue Service (RS). However, for international digital service providers and B2B platforms, the simplicity of the system does not mean a lack of enforcement.

With a standard VAT rate of 18% and strict “Place of Supply” rules for digital services, navigating Georgian compliance requires precise validation of the Taxpayer Identification Number (TIN).

Introduction

The backbone of Georgia’s fiscal infrastructure is the Revenue Service (Semosavlebis Samsakhuri). Georgia utilizes a unified identification system where the Tax ID is central to all business operations, from customs clearance to e-invoicing.

For global enterprises, the challenge lies in verifying the 9-digit Business TIN to ensure legitimate B2B trade. Missteps here prevent the correct application of the Reverse Charge mechanism and expose your business to a standard VAT liability of 18%.

10 Essential Questions About TIN in Aruba

calendar2/2/2026

Aruba operates a distinct fiscal regime within the Kingdom of the Netherlands. Unlike standard VAT jurisdictions, Aruba utilizes a Turnover Tax system (known locally as BBO/BAZV/BAVP) with a combined rate of 7%.

For international businesses and importers, navigating the requirements of the Departamento di Impuesto (DIMP) is critical. Compliance relies on the accurate validation of the Persoonsnummer (PN), which serves as the tax identification number for both individuals and businesses.

Introduction

The backbone of Aruba’s fiscal infrastructure is the Departamento di Impuesto (DIMP). The tax system does not use a European-style VAT but rather a cumulative turnover tax levied on goods and services, including imports (“BBO at the Border”).

For global enterprises, the challenge is ensuring that the 8-digit PN used for customs clearance and invoicing is structurally valid. Since there is no public real-time API for global verification, internal data validation (Syntax Check) is your primary defense against customs blockages.

10 Essential Questions About TIN in Faroe Islands

calendar2/2/2026

The Faroe Islands, while part of the Kingdom of Denmark, operates independently of the EU VAT area. This unique status means businesses cannot rely on EU validation tools (VIES). Instead, they must navigate a distinct local tax system managed by TAKS (Faroese Tax Authority).

For international businesses, seafood importers, and digital service providers, compliance hinges on two specific identifiers: the P-tal (for individuals) and the V-tal (for businesses). Verifying these numbers is critical to managing the 25% VAT (MVG) liability correctly.

Introduction

The backbone of the Faroese fiscal infrastructure is TAKS. Unlike the unified EU system, the Faroe Islands maintains its own registries and tax rules. The local Value Added Tax is known as MVG (Meirvirðisgjald).

For global enterprises, the challenge is verifying the V-tal (Business ID) to clear customs or apply B2B tax rules, as there is no public, open API for global verification. This makes internal data validation (Syntax Check) your primary defense against costly errors.

10 Essential Questions About TIN in Antigua and Barbuda

calendar2/2/2026

Antigua and Barbuda offers a robust environment for tourism and international services. However, the fiscal landscape has become dynamic following the 2024 increase of the Antigua and Barbuda Sales Tax (ABST) to 17%, and the recent 2026 Budget announcements regarding temporary rate adjustments.

For international businesses, investors, and property managers, navigating the requirements of the Inland Revenue Department (IRD) is critical. Unlike jurisdictions with open public registries, Antigua relies heavily on specific identifiers—the TIN and TAN—which must be validated structurally to ensure compliance.

Introduction

The backbone of Antigua and Barbuda’s fiscal infrastructure is the Inland Revenue Department (IRD). The tax system relies on a unique Tax Identification Number (TIN) for all entities and individuals.

For global enterprises, the challenge is double-sided: managing the standard ABST rate (17%) while preparing for temporary reductions (to 7%) announced for mid-2026, all while operating without a public real-time API for verifying tax numbers globally. This makes internal data validation (Syntax Check) your primary line of defense.

10 Essential Questions About TIN in Anguilla

calendar2/1/2026

Anguilla has undergone a major fiscal transformation. Following the 2022 introduction of GST, the system was further reformed in August 2025, splitting the tax regime into a General Services Tax (GST) and a separate Import Goods Tax (IGT).

For international businesses, investors, and importers, the landscape has shifted from a simple tax-neutral jurisdiction to a regulated dual-tax environment managed by the Inland Revenue Department (IRD). Compliance now hinges on the 10-digit TIN, which is mandatory for customs clearance and service invoicing.

Introduction

The backbone of Anguilla’s fiscal infrastructure is the Inland Revenue Department (IRD). With the enactment of the Goods Tax Act and General Services Tax Act (2025 Reforms), the Tax Identification Number (TIN) has become the universal key for all interactions with the government.

For global enterprises, the challenge is ensuring that customer data is structurally valid to meet the distinct requirements of the 13% GST on services and the 9% Tax on imported goods.

10 Essential Questions About TIN in Armenia

calendar2/1/2026

Armenia has rapidly positioned itself as a tech hub in the Caucasus, attracting international businesses and digital nomads. With a modernizing tax administration under the State Revenue Committee (SRC), compliance is becoming increasingly digital and strictly enforced.

For international enterprises and SaaS platforms, navigating the Armenian tax landscape means distinguishing between the universal 8-digit Tax ID (HVHH) and the personal social numbers (PSN), while managing VAT obligations for digital services.

Introduction

The backbone of Armenia’s fiscal infrastructure is the State Revenue Committee (SRC) (in Armenian: Petakan Ekamutneri Komite). Armenia uses a unified identification system for businesses, where the Tax ID serves as the primary key for all interactions with the state, from banking to customs.

For global enterprises, the challenge lies in verifying the TIN (HVHH) to ensure legitimate B2B trade. Missteps here prevent the correct application of the Reverse Charge mechanism and expose your business to a standard VAT liability of 20%.

10 Essential Questions About TIN in Angola

calendar2/1/2026

Angola is one of Africa’s largest economies, actively diversifying beyond oil. Since the introduction of Value Added Tax (IVA) in 2019, the tax landscape has modernized rapidly. For international businesses, compliance is strictly enforced by the Administração Geral Tributária (AGT).

Navigating Angolan compliance requires understanding the NIF (Número de Identificação Fiscal), which serves as the universal identifier for both tax and customs operations. With strict rules on certified invoicing software, verifying the NIF is the first line of defense against penalties.

Introduction

The backbone of Angola’s fiscal infrastructure is the Administração Geral Tributária (AGT). Unlike some jurisdictions with separate VAT and tax numbers, Angola uses a unified system where the NIF covers all tax obligations.

For global enterprises, the challenge lies in verifying this identifier to ensure legitimate B2B trade. Missteps here prevent the deduction of input VAT (currently 14%) and can lead to the rejection of invoices by the AGT’s electronic system.
