EU VAT OSS explained for solopreneurs (without the jargon)

The first cross-border sale is exciting until you realise you might owe VAT in a country you’ve never set foot in. This is the part of European solopreneurship nobody romanticises — so here’s the plain-English version, with the real numbers and the official sources, so you can stop guessing.

This is a practical explainer, not tax advice. Figures are current for 2026 and change — every claim below links to the official source so you can verify it.

The one number that matters: €10,000

Before July 2021, every EU country had its own distance-selling VAT threshold and it was a mess. Those were abolished and replaced by a single EU-wide threshold of €10,000, net of VAT, per calendar year (European Commission — VAT One Stop Shop).

It covers your total cross-border B2C sales across the EU — both digital/“TBE” services (software, courses, downloads) and intra-EU distance sales of goods — added together, not per country.

• Under €10,000/year total: you can simply charge your home country’s VAT rate on cross-border B2C sales. Simple.
• Over €10,000: you must charge the customer’s country VAT rate — French VAT for a buyer in France, German for Germany, and so on.

That second line is where solos panic, because it sounds like registering for VAT in 27 countries. You don’t. That’s exactly what OSS solves.

What the One Stop Shop actually does

The One Stop Shop (OSS) replaced the old MOSS system on 1 July 2021. Instead of registering in every country you sell to, you register for OSS once (in one EU member state), charge each customer their local VAT rate, and file a single quarterly OSS return that reports all of it. The tax authority distributes the money to the other countries for you.

There are three flavours:

• Union OSS — for EU-established businesses selling B2C across the EU. The one most solos use.
• Non-Union OSS — for businesses based outside the EU selling services to EU consumers.
• Import OSS (IOSS) — for imported goods in consignments up to €150.

Worked example: the same €40 course, three buyers

Say you sell a €40 digital course and you’re over the threshold (so you charge the customer’s rate). The price your buyers see — and the VAT you owe to each country via one OSS return — looks like this:

Three different rates, three different totals — and you must keep two non-contradictory pieces of evidence of where each buyer was. One quarterly OSS return reports all of it; a VAT tool applies the rates and keeps the evidence so you’re not doing this by hand.

The 2026 update you should know about

VAT in the EU isn’t frozen. Under the ViDA (“VAT in the Digital Age”) package adopted in March 2025, the scope of OSS expands from 1 July 2026 to cover more B2C supply types — including certain domestic supplies by businesses not established in that country. The direction of travel is clear: more things get pulled into the single OSS return over the rest of the decade, which is good news for a one-person business that just wants one filing.

The mistakes that actually bite solos

• Forgetting the threshold is cumulative. It’s your total cross-border B2C across the EU, not €10,000 per country.
• Not knowing where your customer is. Selling digital goods means you must evidence the customer’s location and apply the right rate. Doing this by hand at quarter-end is misery.
• Ignoring it because “I’m small”. The €10,000 threshold arrives faster than you think once a course or SaaS starts selling.

Doing the rate-and-evidence part on autopilot

The genuinely painful bit isn’t the OSS return itself — it’s applying the correct VAT rate to every sale and keeping the location evidence. If you sell digital products through Stripe, Paddle or similar, this is exactly what dedicated VAT automation is for: it calculates the right rate at checkout and produces the OSS-ready reports.

There’s also a way to hand the whole problem to someone else: sell through a merchant of record (Paddle, Lemon Squeezy), which legally resells your product and owns the VAT in every country. Costs more per sale, removes the obligation entirely — I compared both routes in best payment processors for EU digital products.

Where this quietly leads: your VAT base matters

Here’s the part most guides skip. Where you register for OSS, and how painless your filings are, depends on where your business is established. For a location-independent solo with no obvious home for an EU company, the cleanest base is often an Estonian OÜ via e-Residency — a fully online EU company you run from anywhere.

The real, current costs (verify on the official pages — these change):

• e-Residency digital ID: €150 state fee in 2026, rising to a flat €165 from 1 January 2027; the card is valid 5 years with no annual fee (e-Residency — costs & fees).
• Registering the OÜ online: €265 state fee (Estonian state fees).
• Contact person / legal address: required by the Commercial Code, roughly €200–400/year from a service provider.

None of that does your VAT for you, though. The Estonian OÜ files monthly, and you still need the bookkeeping, invoicing and OSS handling done properly. That ongoing layer — not the company formation — is what actually decides whether the setup is worth it (more in is e-Residency worth it in 2026?). And if you’re not even sure a company is the right structure yet, weigh it against staying a sole trader in sole trader vs OÜ vs freelance.

For most solos who go this route, the least-headache option is a service that bundles the company, invoicing, bookkeeping and a real accountant handling the EU/OSS side:

I compared the full field — done-for-you services versus the self-serve Wise + Quaderno route — in the invoicing & accounting roundup.

The two-minute takeaway

• Just starting / under €10k cross-border: charge home-country VAT, keep clean records, and know the threshold so it doesn’t surprise you.
• Growing past €10k: register for Union OSS, automate the rate-and-evidence step, and file one quarterly return instead of chasing 27 tax offices.
• Borderless and choosing a base: an Estonian OÜ via e-Residency is a clean EU home for this — just budget for the ongoing accounting, not only the setup fees.

The European solo who treats VAT as a system to set up once sleeps a lot better at quarter-end than the one rediscovering it every March.
