I priced out our European expansion three times before I trusted the number. The first two estimates were wrong because I was pricing the wrong things: legal retainers and office space, not the line items that actually show up on the bill. If you're a US B2B SaaS founder weighing Europe, the real cost of expanding to Europe in 2026 is somewhere between 8,000 and 25,000 dollars to get a legal entity, banking, and VAT compliance running, plus 6,000 to 15,000 dollars a month once you have even one person on the ground. Here's where that money actually goes.
Entity setup costs less than you think, if you pick the right country
Setting up a European entity is not the expensive part anymore. The EU rolled out an optional digital-first legal form in 2026 that lets you incorporate in under 48 hours for less than 100 euros, with no minimum share capital, and your tax and VAT numbers get issued automatically as part of registration.
That kills the old assumption that a European subsidiary costs 15,000 dollars and three months of lawyer time before you can invoice anyone. The entity itself is now closer to a rounding error. What still costs real money is everything downstream of the entity: a local business bank account (500 to 2,000 dollars in setup and minimum balance requirements), a registered agent or virtual office if you need a physical address (100 to 400 dollars a month), and payroll infrastructure once you hire.
Jurisdiction matters more than most founders realize before they start comparing. Estonia charges 0% tax on retained profits, so if you're reinvesting revenue into growth rather than distributing it, you pay nothing until you take money out. Bulgaria's corporate tax rate is 10%, rising to roughly 15% combined with dividend tax on distributions, the lowest effective rate in the EU following its euro adoption in January 2026. Compare that to Germany or France, where combined corporate tax can run 25% to 30%, and the jurisdiction choice alone can be worth tens of thousands of dollars a year once you're profitable in-region.
VAT is a compliance cost, not a real cost, but it will eat your time
Here's the part that trips up founders who've never sold outside the US: VAT is not money you lose, it's money you collect and pass through, but getting it wrong is a real cost in penalties and rework.
For B2B sales, when your European customer gives you a valid VAT number, you don't charge VAT on the invoice at all. The reverse charge mechanism means they account for it in their own country. Your only job is validating that VAT number and keeping a record of it. Most founders overbuild for this, hiring a VAT specialist before they've even closed a European deal.
Where it gets real is B2C digital sales, or any B2B deal where the buyer can't provide a valid VAT number. EU VAT for digital services is destination-based, meaning you charge the rate of the customer's country, not your own, and rates range from 17% in Luxembourg to 27% in Hungary. The EU's One Stop Shop (OSS) scheme lets you file one return covering all 27 member states instead of registering separately in each one, which is the single biggest time-saver available and costs nothing beyond your accountant's normal fee to set up.
Budget 1,500 to 4,000 dollars a year for a bookkeeper who understands OSS filing. Do not skip this to save money. A missed VAT filing in one country can trigger a manual investigation that costs more in founder hours than five years of compliance fees.
The real cost is your first European hire, not the entity
Once the paperwork is done, the entity and VAT setup fade into the background and the ongoing cost becomes almost entirely about people. A first European commercial hire, whether that's a country manager, an account executive, or a customer success lead, typically runs 6,000 to 12,000 dollars a month in fully loaded cost across Western Europe once you include statutory benefits, which are meaningfully higher than US payroll taxes. Germany and France both mandate employer contributions north of 20% of gross salary. The UK and Ireland are closer to US norms, which is part of why so many US SaaS companies land their first European hire in London or Dublin regardless of where their biggest customer concentration is.
If you're not ready to run payroll in-country yet, an Employer of Record adds roughly 400 to 1,200 dollars a month per employee on top of salary, which is a fair trade for skipping entity setup entirely on your first hire. It's the right call if you're testing demand before committing capital, and the wrong call once you have three or more people, at which point the EOR markup usually exceeds what a direct entity would have cost.
What to actually budget in year one
For a seed to Series A stage SaaS company doing a real European push, not just accepting inbound European customers, plan for 60,000 to 150,000 dollars in year one, split roughly as: 10,000 to 25,000 in one-time entity, banking, and VAT setup costs, and 50,000 to 125,000 in run-rate cost for one commercial hire plus compliance overhead across the remaining months.
The founders who get burned aren't the ones who spend too much. They're the ones who spend the entity setup budget, hire nobody for six months because they're waiting for "enough signal," and then wonder why European revenue never showed up. The paperwork is now cheap and fast. The cost that actually determines whether Europe works for you is whether you put a person on the ground fast enough to convert the demand that made you consider expanding in the first place.
Frequently asked questions
How much does it cost to set up a European subsidiary for a US SaaS company?
Entity registration itself now costs under 100 euros and takes under 48 hours using the EU's digital-first legal form introduced in 2026. Total setup cost including banking and a registered address typically runs 8,000 to 25,000 dollars once you account for the surrounding infrastructure.
Do I need to charge VAT on sales to European business customers?
Usually no. If your European B2B customer provides a valid VAT number, the reverse charge mechanism means they self-account for VAT in their own country and you invoice without VAT. You still need to validate and record their VAT ID.
What's the cheapest EU country to incorporate in for tax purposes?
Estonia charges 0% tax on retained profits, making it attractive if you're reinvesting rather than distributing. Bulgaria has the lowest headline corporate tax rate in the EU at 10%, roughly 15% combined with dividend tax on distributions.
Should I use an Employer of Record or set up my own entity for my first European hire?
Use an EOR for your first one to two hires while you're validating demand. It costs 400 to 1,200 dollars a month more per employee than direct payroll, but it saves you from entity setup costs before you know the market will work.
How long does European expansion take from decision to first hire?
Entity and banking setup now takes two to six weeks with the digital-first legal form. The longer pole is usually hiring: budget eight to twelve weeks to source, interview, and land a first commercial hire in a competitive European market.
What's the biggest hidden cost founders miss when budgeting for Europe?
Employer payroll contributions. Countries like Germany and France add over 20% in mandatory employer costs on top of salary, which founders budgeting off US payroll math consistently underestimate by tens of thousands of dollars a year.
If you're deciding whether the timing is right before you get to the cost question, that's a separate decision worth making first, with its own signals that show up long before revenue does.
