An Estonian OÜ is almost the ideal structure for a SaaS product, an IT company or an independent developer: the code resides in the cloud, the team is based in different countries, customers are spread across the globe, and the legal entity needs to be just as borderless. An Estonian company for SaaS offers 0% tax on reinvested profits, fully remote management and the EU’s net VAT framework for digital services — exactly what a business needs when it reinvests every margin it earns back into the product.
We put together a turnkey structure: we register the company, sort out VAT in line with your sales model (B2B, B2C, exports outside the EU), set up OSS where required, and handle the accounts with correct processing of reverse charge and digital services. You don’t just get a set of services, but a fully functional framework where the tax logic matches exactly who you’re actually selling your software to and where.
| Topic | Practical explanation |
|---|---|
| Form | OÜ – a private company, 100% foreign-owned, with a minimum share capital of €0.01 |
| Income tax | 0% on reinvested profits; 22/78 when dividends are distributed |
| Management | Fully online: registration, contracts, board resolutions, reporting — via digital signature |
| SaaS for VAT purposes | ‘Electronically supplied services’ |
| B2B within the EU | Reverse charge: 0% VAT; the customer accounts for the tax themselves (subject to verification of the VAT number in VIES) |
| B2C in the EU | VAT at the buyer’s country rate; threshold of €10,000 per year, above which OSS applies |
| VAT threshold in Estonia | €40,000 of taxable turnover — but EU B2B under the reverse charge scheme is not included in this |
| Exports outside the EU | Services to businesses outside the EU — VAT-exempt (export of services) |
| US venture capital | Investors from the US usually expect a Delaware C-Corp — bear this in mind in advance |

For tax purposes, SaaS and software development are classified as ‘electronically supplied services’, and the rules depend on who you are selling to. There are four scenarios that need to be distinguished:
The most common misconception, which deserves separate attention, is discussed in the next section.
A key insight that saves e-residents both money and hassle: the €40,000 threshold for compulsory VAT registration is calculated solely on the basis of taxable supplies made in Estonia. Sales to B2B clients in other EU countries are subject to the reverse charge mechanism and do not constitute Estonian taxable supplies — in other words, they do not count towards the €40,000 threshold.
Practical conclusion: a solo developer or SaaS company with business clients in the EU can issue invoices totalling well over €40,000 per year without being required to register for VAT in Estonia. The obligation arises if you have Estonian clients, B2C sales to consumers, or other Estonian taxable supplies. This is one of the most misunderstood aspects of Estonian VAT — and one of the reasons why the model is so convenient for IT freelancers and B2B SaaS companies. We analyse your client structure and tell you straight: do you need to register now, is voluntary registration beneficial, or can you grow without it?
Launching a product through an Estonian company — a number of services that we bring together under one umbrella:
By ordering a package from a single provider, you get a structure where registration, VAT regime and accounting are tailored to your actual sales model — rather than cobbled together from bits and pieces, which can lead to incorrect invoicing and the reverse charge mechanism ‘breaking down’.
SaaS is the most location-independent business model, and the structure supporting it should be just as flexible. Let’s look at the practicalities for an Estonian company: from registration to correct VAT treatment for digital services.
Registration of an OÜ can be done online via e-Residency (1–5 days), at a notary’s office or by power of attorney. For non-residents, a registered office and a contact person are mandatory; we arrange these at the time of registration. The authorised capital is from €0.01; a resident director is not required, and 100% foreign ownership is permitted.
For B2B clients in the EU, every invoice must include the client’s VAT number and a reverse charge notation (‘VAT reverse charged, Art. 196 EU VAT Directive’) – in which case you charge 0% VAT, and the client accounts for the tax. Before applying the reverse charge, the client’s VAT number must be checked in VIES: if the number is invalid, the client is considered a ‘non-business’ entity, and the reverse charge does not apply. An invoice is required for every sale, including B2B transactions with zero VAT. The invoice may be in any language (Estonian is not mandatory). It is precisely incorrect invoices and unverified VAT numbers that most often cause problems with the reverse charge mechanism – we set up invoicing so that it passes customers’ AP checks.
OSS is required when you sell digital services to consumers (B2C) in other EU countries and the turnover from such sales exceeds €10,000 per year: in this case, VAT is charged at the buyer’s country’s rate but declared in a single quarterly return via Estonia. If you sell only B2B or only outside the EU, OSS is generally not required. For a mixed model (partly B2B, partly B2C), OSS becomes relevant. We determine whether you fall under the requirement and register you for OSS if necessary.
| Tax | How it applies to SaaS |
|---|---|
| Income tax | 0% on reinvested profits; 22/78 when dividends are distributed |
| VAT, rate | 24% (Estonia’s standard rate) |
| B2B within the EU | Reverse charge, 0% (provided the VAT number is valid in VIES) |
| B2C within the EU | VAT at the buyer’s country rate; over €10,000 per year — via OSS |
| Exports outside the EU | Services to businesses outside the EU — 0% (export of services) |
| VAT registration threshold | €40,000 of Estonian taxable supplies (EU B2B reverse charge not included) |
An Estonian company does not come with an automatic bank account — most SaaS founders use fintech and payment providers (Wise Business, Revolut, Stripe, Paddle), which are well suited to the subscription model. We prepare the documents and product description for onboarding. It’s worth noting separately that, when processing subscriptions, Paddle and similar Merchant of Record providers take responsibility for VAT compliance — this is a separate scenario that we factor into our accounting.
If your plan involves a funding round from a US venture capital firm, US investors usually expect a Delaware C-Corp, and an Estonian OÜ may complicate this process. Many SaaS founders start out ‘lean’ with an Estonian company and only restructure once a US funding round becomes a realistic prospect. We’ll be frank about this: if a Delaware C-Corp is on your horizon, it’s worth making an informed decision in advance, rather than after the event. For bootstrapped, angel-backed and EU-focused SaaS companies, Estonia is almost the perfect home.
