Avalara vs Taxually for Cross-Border Sellers 2026

Avalara and Taxually represent two completely different layers of the compliance stack. Avalara is primarily a real-time tax calculation engine with add-on filing services, built for complex global enterprises. Taxually is a compliance, registration, and filing specialist that aggregates historical data to submit your VAT returns—it does not calculate tax at checkout.

If you need a system to calculate tax live in the shopping cart, Avalara does that; Taxually does not. If you already have a checkout calculator (like Stripe Tax or Shopify Tax) and just need someone to legally file your EU IOSS and UK VAT returns, Taxually is the answer.

1. Local VAT / Sales Tax Filing

Section titled “1. Local VAT / Sales Tax Filing”

Avalara: Offers MTD filing via its VAT Reporting tool. It can calculate the tax on your sales, generate the reports, and submit them to HMRC.

Taxually: A licensed UK VAT agent that files MTD returns on your behalf. Taxually imports your sales data from various channels, prepares the return, and handles the submission natively.

Verdict: Tie on capability. Both provide full UK MTD filing. Taxually is much easier to set up for this specific task.

2. EU IOSS

Section titled “2. EU IOSS”

Avalara: Calculates IOSS VAT at checkout. However, it does not act as your IOSS intermediary. You still must hire an external intermediary to submit your monthly returns.

Taxually: Acts as your registered IOSS intermediary. It takes legal responsibility for your IOSS registration, aggregates your sales data from Shopify/Amazon/Stripe, and files the return for you. It does not, however, calculate the tax at checkout.

Verdict: They solve different halves of the problem. Avalara calculates; Taxually files.

3. EU OSS

Section titled “3. EU OSS”

Avalara: Calculates OSS at checkout and offers managed filing services to submit the quarterly returns on your behalf.

Taxually: Specializes in OSS filing. Taxually manages the OSS registration, pulls in the data, and submits the quarterly returns across the EU.

Verdict: Both handle OSS filing well. Taxually is highly specialized in this exact service and is significantly more accessible for non-enterprise sellers.

4. US Sales Tax

Section titled “4. US Sales Tax”

Avalara: A powerhouse for US sales tax. Handles real-time calculation, granular taxability, exemption certificates, and files returns in all 50 states natively.

Taxually: No US sales tax support whatsoever. Taxually is strictly focused on European and UK VAT regimes.

Verdict: Avalara wins completely. Taxually does not operate in the US.

5. VAT Calculation at Checkout

Section titled “5. VAT Calculation at Checkout”

Avalara: Real-time calculation engine that plugs into checkout flows to determine the exact tax rate live.

Taxually: Does not do checkout calculation. It is an after-the-fact compliance tool that processes data for return filing.

Verdict: Avalara wins. If you use Taxually for filing, you must pair it with a calculation engine (like Shopify Tax, Stripe Tax, or Quaderno) at checkout.

6. Platform Integrations

Section titled “6. Platform Integrations”

Avalara: 700+ integrations spanning ERPs, POS systems, and enterprise e-commerce platforms.

Taxually: Natively integrates with Shopify, WooCommerce, Amazon, eBay, Etsy, and Stripe. Its integrations are designed to pull historical sales data to prepare VAT returns, not to sit in the live checkout flow.

Verdict: Avalara is for enterprise tech stacks. Taxually integrates perfectly with standard e-commerce and marketplace setups for data aggregation.

7. Pricing Model

Section titled “7. Pricing Model”

Avalara: Quote-based enterprise pricing. Usually $8k–$20k+ annually, plus implementation fees.

Taxually: Subscription-based, starting around €49–99/month depending on the required services (IOSS, OSS, UK MTD) and transaction volume.

Verdict: Taxually is massively more affordable for businesses that simply need EU/UK VAT filing and registration services.

8. Setup Complexity

Section titled “8. Setup Complexity”

Avalara: Very high. Requires IT teams and a lengthy implementation process.

Taxually: Low to moderate. Setup involves connecting your sales channels and completing the necessary VAT/IOSS/OSS registrations, which Taxually’s team facilitates.

Verdict: Taxually is significantly faster and easier to deploy.

9. Reporting and Records

Section titled “9. Reporting and Records”

Avalara: Deep, global, enterprise-ready reporting with long-term data retention for audits.

Taxually: Because Taxually legally files your returns, it retains your authoritative compliance archive. It securely holds the 10-year records required for IOSS, alongside all submitted returns and tax authority receipts.

Verdict: Both provide audit-grade records. Taxually’s is highly streamlined for EU VAT compliance specifically.

10. Ecosystem / Wider Product

Section titled “10. Ecosystem / Wider Product”

Avalara: A massive, holistic global tax suite spanning calculation, customs, e-invoicing, and filing.

Taxually: A focused EU/UK compliance service handling registrations, IOSS intermediary duties, and multi-country VAT filings (including local registrations for warehouse stock).

Verdict: Avalara covers global breadth. Taxually focuses deeply on EU/UK regulatory filing.

11. Support

Section titled “11. Support”

Avalara: Standard enterprise SLAs, varying quality.

Taxually: Excellent, compliance-specific support. Taxually’s team consists of VAT experts who help you navigate European tax registrations and regulatory nuances directly.

Verdict: Taxually wins on practical EU VAT domain expertise for SMBs.
