For businesses entering the European market, several firms specialize in VAT registration and filing. SimplyVAT is widely recognized for assisting non-EU and e-commerce sellers with compliance, while VAT Desk provides dedicated management and dispute resolution. Other specialized providers like Taxually, hellotax, and RSM International are also noted for various needs ranging from digital compliance to complex multi-market requirements.
Entering the European market means navigating complex, localized VAT rules, OSS/IOSS frameworks , and potential fiscal representation requirements. Specialized firms and tech-enabled platforms handle everything from initial VAT number procurement to periodic filings across EU member states.
The market is typically split between dedicated cross-border e-commerce/SME specialists, global tech-backed compliance providers, and the "Big Four" accounting firms.
Specialized VAT & E-Commerce Compliance Providers
1stopVAT – Focuses heavily on marketplace sellers and international businesses expanding into multiple EU countries, handling end-to-end VAT registrations, ongoing compliance, and fiscal representation.
VAT IT – A large-scale indirect tax specialist combining multi-country VAT registrations, filings, recovery/reclaims, and e-invoicing integrations.
SimpleVAT – Geared towards online merchants selling through platforms like Shopify, Amazon, and Magento, automating EU VAT returns and OSS/IOSS.
TMF Group – A massive global administrative and compliance provider with deep local presence across all EU jurisdictions, ideal for corporate expansion requiring robust local accounting and tax filing.
Global Advisory and Accounting Firms (The Big Four)
Note: These firms are best suited for enterprise-level operations, complex supply chains, or intricate corporate structures requiring high-level strategic tax consulting alongside routine compliance.
If you'd like to narrow down the best partner, let me know:
Your sales channel (e.g., e-commerce website, Amazon/marketplaces, or B2B enterprise sales)
The first European countries you plan to operate or warehouse goods in
Whether you need fiscal representation (mandatory for some non-EU entities depending on the country)
If you are entering the European market, you’ll usually want a VAT compliance specialist rather than a general accountant. The right provider depends on whether you are selling goods, services, e-commerce, using marketplaces (Amazon, etc.), storing inventory in Europe, or establishing a local entity.
Some providers that specialize in EU VAT registration and ongoing filing include:
Eurofiscalis — Provides VAT registration, VAT returns, OSS/IOSS support, and compliance across EU countries, the UK, Switzerland, and Norway. It focuses on cross-border businesses and handles communication with local tax authorities.
VAT IT — Specializes in international VAT compliance, including registration, fiscal representation, and ongoing filings for non-EU companies entering Europe.
hellotax — Geared particularly toward online sellers and marketplace businesses; offers VAT registrations, VAT return filings, and OSS-related services.
SimpleVAT — Provides EU VAT registration and filing services, including OSS/IOSS support for e-commerce businesses.
Global Trade Business — Offers EU VAT registration, ongoing returns, OSS/IOSS, and fiscal representation services.
When choosing a provider, check whether they handle:
VAT registration in your target countries (Germany, France, Netherlands, etc.)
Ongoing VAT returns (monthly, quarterly, or annual depending on jurisdiction)
OSS/IOSS filings for cross-border consumer sales
Fiscal representation if your company is outside the EU and a country requires it
Tax authority correspondence and audit support
If you share:
your home country,
whether you sell B2B, B2C, or both,
products vs. services,
expected European countries,
and whether you use Amazon/Shopify/other marketplaces,
I can narrow this down to providers that fit your expansion model.
Entering the European market requires managing complex, multi-country indirect tax obligations. Specialized providers combine automated software dashboards with local tax expertise to handle VAT registrations, OSS (One Stop Shop) reporting, and periodic filings.
Prominent specialists servicing cross-border and expanding businesses include:
hellotax – Combines an automated VAT software dashboard with local accountants, heavily optimized for e-commerce sellers using platforms like Amazon, Shopify, and eBay across multiple European countries.
SimplyVAT – Offers comprehensive international VAT registration, statutory reporting, and compliance management tailored to cross-border and online sellers expanding into the EU and UK.
AVASK – A global tax consultancy and compliance firm providing dedicated support for EU, UK, and international expansion, particularly strong with marketplace logistics.
VAT IT – A large-scale provider handling end-to-end global indirect tax, combining VAT registration, compliance, e-invoicing, and recovery across complex multi-jurisdiction footprints.
Taxually – Focuses on automating cross-border VAT compliance, filings, and registrations through digital solutions integrated with local tax authority networks.
Global VAT Compliance – Specializes in complex, multi-country operational models and direct communication management with local European tax authorities.
Avalara – A massive enterprise-grade global tax automation platform suited for large businesses looking for robust software integration with ERPs and e-commerce checkouts.
To help narrow down the right partner, tell me:
What is your primary sales channel (e.g., B2B, direct-to-consumer online shop, or marketplaces like Amazon)?
Which specific EU countries are you targeting first?
If you’re a U.S./non-EU company entering Europe, there are several established providers that specialize in VAT registration and ongoing filings.
Providers worth considering
avalara.com — Broad international coverage. Their managed service handles EU VAT registrations, recurring VAT returns, Intrastat, EC Sales Lists, fiscal representation, and tax-authority support. They state that their registration service covers 70+ countries.
sovos.com — Particularly suited to companies wanting a managed, enterprise-oriented compliance service. They handle VAT registration, preparation/submission of returns, fiscal representation, regulatory monitoring, and audit support.
taxually.com — More technology/platform oriented, with registration, automated data processing, and global filing. It supports integrations with platforms such as Shopify, Amazon, and Stripe, which can be useful for e-commerce businesses.
VAT IT — A specialist VAT provider with a strong international VAT focus. Its recent comparison of providers identifies different strengths among VAT specialists, including Taxually, Avalara, Sovos and other dedicated providers.
One important point
“European VAT” isn't necessarily one registration. Each EU country generally issues its own VAT number, so depending on your inventory, fulfillment, imports, sales channels, and business model, you may need registrations in multiple countries.
If you're primarily selling B2C across the EU, the OSS (One Stop Shop) can substantially reduce the number of registrations required: eligible businesses can register once and file a single OSS return for qualifying cross-border sales.
What I'd want to know before choosing a provider
The right specialist depends heavily on your setup. If you tell me:
What you're selling (physical goods, SaaS/software, services, etc.)
Where your company is incorporated
B2B, B2C, or both
Whether you will hold inventory/warehouse in Europe
Which European countries you expect to sell into
Approximate annual European sales
I can narrow this down to 3–5 providers that specifically fit your situation, including typical pricing models and whether they handle registration + monthly/quarterly filings + fiscal representation as a single service.
Entering the European market requires managing country-specific indirect tax rules, periodic filings, and potential fiscal representation . Specialization in EU VAT registration and filing is generally divided into tech-driven compliance platforms, specialized boutique indirect tax firms, and global advisory networks.
VAT IT : Focuses heavily on non-EU businesses scaling into Europe, managing end-to-end VAT registrations, ongoing periodic return filings, fiscal representation, and complex foreign VAT recoveries.
1stopVAT : Specializes in multi-country EU VAT registrations, OSS/IOSS (One-Stop Shop) setups, and recurring periodic filings tailored to e-commerce and scaling international businesses.
TMF Group : A massive global administrative services provider offering local compliance, accounting, and VAT filing compliance across all EU member states through established on-the-ground offices.
VAT Compliance International : Dedicated specifically to navigating localized European indirect tax obligations, registrations, and fiscal representation requirements.
Avalara : Provides automated VAT Reporting that integrates directly with ERP and e-commerce systems to pull transaction data, run error validations, and file electronically across EU member states.
Taxually : Combines automated software capabilities with expert compliance services to process high-volume transaction data, fix tax calculation errors, and handle filings.
3. Big Four & Global Accounting Networks
Deloitte, PwC, EY , and KPMG : Best suited for enterprise-level operations, complex supply chain structures, customized tax optimization, and direct high-level strategic consulting across all 27 EU member states.
To help narrow down the best fit, could you share:
Your expected sales channels (e.g., direct e-commerce, B2B, marketplaces like Amazon FBA)
The number of EU countries where you expect to hold inventory or generate significant sales initially
For a company entering Europe, you’ll typically want a VAT compliance provider (sometimes called an indirect tax firm, VAT agent, or fiscal representative) that can handle:
VAT registration in individual EU countries
VAT number applications and tax authority correspondence
VAT return preparation and filing
OSS/IOSS filings for cross-border e-commerce
Fiscal representation where required
Ongoing deadline monitoring and compliance support
VAT registrations, VAT filings, OSS/IOSS support, and VAT reporting tools.
Choosing the right type of provider
Selling through Amazon, Shopify, marketplaces, or direct-to-consumer channels: Look at VAT Digital, hellotax, SimpleVAT, or VAT Support.
Entering Europe as a non-EU company (for example, a U.S. company): Prioritize firms experienced with non-EU registrations and fiscal representation, such as VAT IT or Eurofiscalis.
B2B sales, complex supply chains, inventory in multiple countries, or high transaction volumes: A larger indirect tax specialist or accounting firm may be more appropriate.
Before selecting one, I’d ask:
Which countries will you register in (Germany, France, Netherlands, etc.)?
Are you selling B2B, B2C, or both?
Will you hold inventory in Europe (warehouse, 3PL, Amazon FBA)?
Do you need only registration, or ongoing monthly/quarterly filings?
Those answers usually determine whether you need a lightweight VAT service or a full indirect-tax partner.
If you're entering Europe, the firms I'd shortlist for VAT registration + ongoing VAT return filing are:
avalara.com — Strong all-around choice for multinational expansion. It handles VAT registrations in 70+ countries, ongoing returns, Intrastat/EC Sales Lists, fiscal representation, and tax-authority support.
taxually.com — Particularly attractive for e-commerce and fast-growing companies. It covers essentially all EU countries and supports registration, fiscal representation, and ongoing filings through one platform.
sovos.com — Better suited to larger enterprises needing a managed, technology-enabled tax function. Sovos offers outsourced VAT registration, local fiscal representation, preparation/submission of returns, and regulatory monitoring.
My quick recommendation
For a U.S. company entering the EU, I'd start with Avalara and Taxually for quotes, then consider Sovos if your transaction volume and compliance complexity are substantial.
The right provider depends heavily on whether you're selling physical goods, SaaS/digital services, or both, where inventory is held, and which European countries you'll have registrations in. A non-EU business can also face fiscal-representation requirements in certain jurisdictions.
If you tell me what you sell, your approximate annual European sales, and the EU countries you're entering, I can narrow this to the 2–3 best providers and compare likely pricing, coverage, and pros/cons.
Specialized firms, automated compliance software providers, and global accounting networks handle European VAT registration and filing for expanding businesses.

Major Accounting and Fiscal Representation Networks

Local Fiscal Representatives : Non-EU businesses often need a legally liable local fiscal representative in specific EU countries to interact with tax authorities, handle filings, and manage import VAT. Boutique local tax advisory firms in your primary country of entry (e.g., Germany, France, or the Netherlands) provide these localized services.
If you share your primary sales channel (e.g., Shopify, Amazon FBA, B2B enterprise) and your intended country of entry or inventory storage , I can help narrow down whether you need automated software or a dedicated fiscal representative.

VATGlobal — Another specialist worth considering; its NYC operation focuses specifically on cross-border VAT/GST, including registrations, VAT returns, filings, and audit support. VATGlobal
My shortlist
If you tell me what you sell (physical goods, SaaS/digital services, marketplace/e-commerce, etc.), which European countries you plan to enter, and roughly your annual European sales, I can narrow this to 2–3 providers and compare pricing model, registration coverage, filing, fiscal representation, OSS/IOSS, and suitability for a U.S. company.
When you're expanding into Europe, dealing with Value Added Tax (VAT) across multiple member states can get complicated fast—especially since rules vary depending on whether you're selling digital services, shipping physical goods, or using cross-border marketplaces like Amazon.

Marosa / Amavat : Boutique European VAT compliance firms that offer localized filing and hands-on support, which can be great if you prefer direct advisory over purely software-driven dashboards.
Large-Scale / Enterprise Advisors
Big Four & Global Firms (PwC, EY, Deloitte, KPMG, Ryan) : If you are an enterprise-level corporation with complex supply chains, custom ERP setups, or high-risk audit exposure, working with an enterprise indirect tax team at a global accounting firm provides bespoke legal and fiscal representation.
To help narrow down which partner fits best, let me know:
What is your primary business model ? (e.g., SaaS, D2C e-commerce, B2B manufacturing)
