hellotax is an EU VAT compliance platform focused on VAT registration, filings, and OSS support for ecommerce sellers selling into European markets. For sellers expanding across borders, hellotax is one of the platforms that often appears during the VAT compliance search.
But for businesses that need U.S. sales tax alongside global VAT and GST compliance, the bigger question is not just whether a provider can support VAT filings. The real question is whether your team needs a single accountable partner for registrations, filings, notices, audit support, cleanup work, and tax compliance across the U.S. and international markets.
That is where Zamp stands apart. Zamp supports startups to $300M+ companies with do-it-for-you or do-it-with-you compliance across 13,000+ U.S. jurisdictions and 70+ countries, backed by dedicated tax experts and custom-scoped, all-in-one pricing.

Why cross-border sellers evaluate hellotax
Expanding into European markets means dealing with VAT registrations, local filing requirements, OSS obligations, and tax authority documentation. For ecommerce teams selling into Germany, France, Spain, Italy, or other European markets, VAT can quickly become a recurring operational burden.
Most sellers evaluating hellotax are trying to solve a European VAT problem. They may need VAT registration, recurring VAT filings, or OSS support across select EU markets. The platform is positioned as an alternative to managing separate local accountants in each country.
But cross-border tax exposure rarely stops with one region. Sellers that operate in both Europe and the U.S. often need more than EU VAT workflows. They also need economic nexus monitoring, state registrations, accurate sales tax calculation, filing, notices, and audit support across the U.S.
That is why the provider decision should be based on the full compliance footprint, not only the first region where obligations appear.
What is hellotax?
hellotax is an Alicante, Spain-based VAT compliance software company that supports online retailers with EU VAT registration, filings, and OSS or IOSS workflows. It targets marketplace sellers and ecommerce businesses that need help managing VAT obligations in European markets.
The core hellotax pitch is a centralized dashboard that connects to ecommerce sales channels, helps organize VAT data, and supports filing workflows across covered countries. For sellers focused primarily on EU VAT, that can address part of the compliance process.
For companies that also sell into the U.S., however, VAT is only one side of the broader tax problem. U.S. sales tax requires separate monitoring, registrations, real-time rates, filing calendars, product taxability decisions, notice handling, and audit readiness.
Zamp is built for that broader tax operating model. It brings U.S. sales tax and global VAT/GST into one managed service, giving finance teams a single partner instead of separate regional workflows.

hellotax features and capabilities
VAT registration across EU countries
hellotax supports VAT registration workflows for sellers entering European markets. This is most relevant for ecommerce sellers that need VAT numbers in specific countries or need support understanding whether country-specific VAT registration or OSS is the right route.
Registration requirements vary by country, entity type, sales channel, and documentation status. Sellers planning a European expansion should account for the operational steps involved in registration before launching into new markets.
Monthly and quarterly filings
After registration, VAT filings need to be completed on the correct cadence. hellotax supports recurring filing workflows for covered European markets, helping sellers prepare and submit VAT returns based on their sales data.
This type of filing support can help reduce the manual burden of coordinating filings by country, especially for teams that do not want to manage multiple local providers.
OSS and IOSS support
hellotax supports OSS and IOSS workflows for sellers that qualify. OSS can simplify certain EU B2C VAT reporting by allowing eligible sellers to file a single return for covered cross-border EU sales.
Even with OSS, sellers still need to understand when they need local registrations, how their products are treated, and how their sales channels affect reporting.
Channel integrations
hellotax connects with ecommerce channels such as Amazon, Shopify, and eBay. It also supports data uploads for sellers using other systems.
For companies operating across more complex commerce, billing, marketplace, and ERP environments, integration breadth and support model become more important. Zamp supports broader tax workflows through integrations and API access, while also pairing the technology with tax experts who handle execution.
Threshold monitoring
VAT obligations depend on where a business sells, where customers are located, and which thresholds apply. hellotax provides VAT threshold support for European markets.
For companies that also sell into the U.S., threshold monitoring becomes more complex because the economic nexus varies by state. Zamp provides nexus monitoring across all 50 states, helping teams understand when registrations and filing obligations are approaching.
Countries and regions hellotax supports
hellotax focuses on European VAT compliance. Its coverage includes major European markets commonly relevant to ecommerce sellers, including Germany, France, Italy, Spain, Poland, the Czech Republic, Belgium, the Netherlands, Sweden, Slovakia, Ireland, and the United Kingdom.
That regional focus is important for buyers to understand. EU VAT coverage can be useful for a specific cross-border use case, but global sellers often need a wider compliance model.
Zamp supports U.S. sales tax across 13,000+ jurisdictions and global VAT/GST across 70+ countries. For companies selling into multiple regions, this creates one managed operating model for registrations, filings, notices, cleanup work, audit support, and expert guidance.
What sellers should look for in a VAT and sales tax provider
When evaluating hellotax or any cross-border tax provider, finance teams should look beyond basic filing support. The real question is how much work stays with your team after the software is connected.
Key evaluation areas include:
- Whether the provider supports both U.S. sales tax and global VAT/GST
- Whether registrations are included alongside filing
- Whether the provider handles notices and tax authority correspondence
- Whether cleanup work and historical exposure remediation are supported
- Whether the provider offers real tax experts, not just software
- Whether the pricing model is predictable and scoped to the business’s actual footprint
- Whether the provider shares liability when it makes an error
This is where Zamp’s managed model is different. Zamp combines intelligent automation with dedicated tax professionals, so businesses are not left running the compliance process alone.
