Best VAT Tool 2026 - Frequently Asked Questions
What are the best VAT and sales tax tools?▾
Avalara and Vertex are the enterprise standards with the broadest jurisdiction coverage and filing services. TaxJar is strong for US sales tax and e-commerce. Quaderno is a good fit for SaaS and digital products selling internationally. Alternatively, using a merchant of record like Paddle or Lemon Squeezy removes the problem entirely, since they become the seller and handle it.
Do I need to charge VAT to customers in other countries?▾
If you sell digital services to consumers in the EU, UK, and a growing list of other countries, yes - you generally must charge VAT at the customer's local rate and remit it there, often from the first sale with no threshold. Rules differ for B2B (where reverse charge usually applies) and for physical goods. This is the single most commonly overlooked obligation for small software businesses.
What is the simplest way to handle international sales tax?▾
Use a merchant of record. Paddle and Lemon Squeezy become the legal seller, which means the VAT and sales tax obligation is theirs, not yours - no registrations, no filings, no thresholds to monitor across dozens of countries. You pay a higher transaction fee for it. For a small team, the alternative is a genuinely significant ongoing compliance burden.
