Taxdoo shut down its VAT compliance business in April 2026 and pointed customers to Marosa — a good fit for mid-sized brands, not for a €20k/year shop. Here's what actually fits.
Taxdoo shut down its VAT compliance business on 30 April 2026 and pointed its customers to Marosa. That's a reasonable recommendation if you're a mid-sized brand with a dedicated finance team — Marosa, and the handful of tools like it, do full-service EU VAT compliance well. But their pricing starts around €49 a month, and that's before you factor in onboarding calls, account managers, and minimum contract terms built for sellers doing hundreds of thousands of euros a quarter.
If you're a shop doing €20,000–€40,000 a year across two or three channels, that math doesn't work. You don't need a compliance department. You need a summary you can hand to your accountant every quarter, produced from the sales data you already have.
What actually goes into an OSS return
Strip away the enterprise tooling and a Union OSS return is a fairly mechanical document: for every EU country your buyers were in, how much you sold at each VAT rate, converted to EUR at the correct exchange rate, for that one quarter. IOSS is the same idea but monthly, and only for goods imported into the EU under €150.
The hard part was never understanding OSS — it's assembling the data. A seller running Shopify plus an Etsy shop plus occasional eBay orders has three exports in three different shapes, in three different currencies, and has to manually sort every line into "domestic," "OSS," "IOSS," or "not in scope" (B2B sales with a VAT number, non-EU destinations) before a single number can go on the return.
What Vatlio does instead
Vatlio connects to Shopify, Etsy, eBay, and WooCommerce directly, and takes a CSV for anything else. It classifies every line automatically — domestic vs. OSS vs. IOSS vs. out of scope — using the same rules a compliance service would apply, checks the VAT rate against the official EU rate database, and converts non-EUR sales using the European Central Bank's period-end rate (the rate the regulation actually requires, not the transaction-date rate most spreadsheets use by mistake).
At the end of the quarter, you get a country-by-country summary, plus two export formats: a BOP CSV formatted for Germany's official "Mein BOP" OSS import (both the standard OSS and the separate IOSS format), and a plain accountant CSV that works anywhere.
What Vatlio doesn't do
It doesn't file your return. That's a deliberate line, not a missing feature — filing means taking on legal responsibility for what gets submitted to a tax authority, and for a €15/month tool that's the wrong trade for both of us. Your accountant reviews the summary, confirms it against what they already know about your business, and files it through your country's OSS portal in a few minutes instead of a few hours.
It also doesn't replace your accountant's judgment on genuinely ambiguous cases — mixed B2B/B2C shops, marketplace-collected VAT, or anything TEDB's official rate database doesn't have a clean answer for gets flagged for review rather than guessed at silently.
Pricing, for comparison
Free to try on real data (one store, current quarter, watermarked exports). Starter is €15/month for unlimited stores and full exports. Agency is €59/month if you're an accountant managing multiple clients' OSS filings from one dashboard, with API access.
If Taxdoo's closure left you looking for something that fits a small shop's actual size and budget — start free and connect your first store.
Not tax advice. Vatlio prepares OSS/IOSS return summaries from your sales data. It does not file returns with any tax authority and does not provide tax advice — your accountant stays in control of the filing.
