e-Residency companies — B2B EDI and PEPPOL access

The ~28,000 OÜ companies incorporated via e-Residency since 2014 are a world-unique stress test for e-invoicing policy. An OÜ can be owned by a Thai founder, operated from Berlin, billing a Spanish customer — and remain tax-resident in Estonia. Service providers Xolo OÜ, Companio, 1Office and Leapin package PEPPOL access through Pagero or Tradeshift, handle monthly KMD INF, and issue e-arve XML invoices for Estonian customers.

History — from the first e-Resident OU 2015 to 28k in 2024

The first OU incorporated via e-Residency appear in 2015 — about 200 that year. LeapIN (renamed Xolo in 2018) is the first to industrialise the all-in-one offer: incorporation, accounting, invoicing, tax, all on a EUR 30-60 / month SaaS subscription. The model spreads quickly — Companio (founded by two Spaniards in Tartu), 1Office (Tallinn), Leapin (the original Xolo name reused elsewhere), NumberOS (Tallinn).

In 2019, PEPPOL access is bundled into the packages — e-Resident OU can issue PEPPOL BIS Billing 3.0 UBL directly to EU customers, via Pagero (Xolo), Tradeshift (Companio) or Unifiedpost (Leapin). The 2020-2022 Covid boom adds ~10,000 OU. As of 1 January 2024, there are ~28,000 cumulative OU and ~22,000 active.

Governance — RIK + EMTA + service providers

Governance combines three actors:

• RIK / Ariregister — maintains the OU register and validates incorporations in real time (10-15 minutes).
• EMTA — handles the monthly KMD (Käibedeklaratsioon), the KMD INF SAF-T, and corporate income tax on distributed dividends (Käibemaks standard rate 22-24%).
• Private service providers — Xolo OÜ, Companio, 1Office, Leapin, NumberOS: they handle incorporation, accounting, invoicing, reporting, AML and the legal address.

Operation schema — Xolo, Companio, Leapin

# Typical operation of an e-Resident OU (high level)

Step 1: Incorporation (10-15 min)
  - digi-ID login at ariregister.rik.ee OR via service provider
  - Articles of association (default or custom), capital 0.01-2,500 EUR
  - Legal address provided by service provider (Xolo, Companio)
  - Fees: EUR 265 (RIK) + EUR 50-80 (service provider)

Step 2: Business banking
  - Wise Business (most common for non-EU residents)
  - LHV / SEB / Swedbank (stricter KYC)
  - Revolut Business EE

Step 3: e-arve invoicing
  - Service provider (Xolo Invoice / Companio Billing) issues e-arve
  - e-arve XML for EE customers, PEPPOL BIS 3.0 UBL for EU customers
  - PEPPOL access via Pagero (Xolo) / Tradeshift (Companio) / Unifiedpost (Leapin)

Step 4: Accounting + KMD INF
  - Auto-sync bank account + Stripe + Wise
  - KMD INF generated monthly (VAT-registered if > EUR 40k / 12 months)
  - Käibedeklaratsioon filed with eMTA by the 20th of the following month
  - Annual accounts filed with Ariregister (June N+1)

Step 5: Dividend distribution (optional)
  - Corporate tax: 20% on distributed dividends
  - No tax as long as profits stay reinvested
  - Usually called the "Estonian model" in tax analysis

Service-provider comparison

Adoption — 28k companies, 50+ countries

• ~28,000 OU formed via e-Residency since 2014 (e-Residency programme, 2024 data).
• ~22,000 active OU (turnover > 0), geographic split: Europe (~60%), Asia (~20%), Americas (~15%), rest (~5%).
• ~EUR 30M / year estimated tax revenue for the Estonian state (e-Residency programme estimate).
• ~80% use a service provider — Xolo leads (~30% market share), Companio ~20%, others ~50%.
• Top 5 use cases: SaaS / freelance tech (~40%), consulting (~25%), e-commerce dropshipping (~15%), crypto (~10%), holding (~10%).

Common pitfalls

• Thinking OU = exemption. An OU is subject to corporate income tax (on distributed dividends) at the Käibemaks standard rate. No magic optimisation.
• CFC rules. EU 27 + UK + USA apply CFC rules. If the OU lacks Estonian substance (employee, office, real activity), it can be reclassified for tax.
• Late KMD INF = penalty. A late KMD INF triggers an EMTA penalty + risk of LHV account freeze. Service providers manage filing automatically.
• Legal address required. An OU must have a postal address in Estonia. Without a service provider, you must rent premises — expensive.
• LHV / SEB / Swedbank KYC. Very strict since 2022 for non-EU e-residents. Many OU end up opening accounts at Wise Business or Revolut Business.
