AccountsOS Is Now Live in 21 Countries

A quick milestone post, because this one matters. AccountsOS is now live in 21 countries.

We started the year at twelve. Over the course of 2026 we added nine more: Singapore, the Netherlands, Sweden, India, Switzerland, Canada, Austria, Norway and New Zealand. That brings the full list to:

United Kingdom, Ireland, Bulgaria, the United Arab Emirates, Australia, the United States, Hong Kong, Turkey, the Isle of Man, Guernsey, Germany, Denmark, Singapore, the Netherlands, Sweden, India, Switzerland, Canada, Austria, Norway and New Zealand.

What "live in a country" actually means here

It would be easy to add a flag and a currency and call a country supported. We don't count that. For us, a country is live only when it has:

• The correct tax authority and filing format, from HMRC and Companies House in the UK to IRAS and ACRA in Singapore, to Inland Revenue and the Companies Office in New Zealand.
• The right company registry for that jurisdiction.
• Local entity types, because the structure changes the tax. A UK Ltd, a Dutch BV, a New Zealand Look-Through Company, a Norwegian AS.
• Real tax rates, thresholds and deadlines, sourced from official government pages, with Finn citing the source when it answers a question.
• Local currency and date formats, so the books read correctly to a local accountant.

Every one of the nine new countries clears that bar. This is encoded local tax knowledge, not a translation layer.

Why this happened so fast

Adding a country to accounting software has always been the expensive part. You need someone who understands that country's tax law, then you build it, test it, and maintain it. That's why most tools are single-country.

AI changes the economics. The research and encoding that used to need a local hire per market is now something we can do quickly and verifiably, while keeping the parts that must stay exact, the money math and the compliance, deterministic. That's what let us move from 12 to 21 in a matter of days rather than years.

What it means if you're a founder

If you operate in more than one country, you no longer need a separate accounting product, subscription and login for each. One AccountsOS account runs every company you own across all 21 jurisdictions. You switch between them with a click, and Finn loads the right tax rules, currency, registry and deadlines for whichever company you're looking at.

If you operate in just one of these countries, you get an AI CFO that genuinely understands your local rules rather than a UK tool with the serial numbers filed off.

What's next

The rollout isn't finished. More countries are on the runbook, and we're deepening direct tax-authority filing in each country as their digital systems allow. The goal is simple: wherever your company is registered, AccountsOS should already know the rules.

You can see the full breakdown, including entity types and tax detail per country, on the countries page. If you want a deeper look at how cross-border accounting works on one platform, read accounting software for multiple countries.

How many countries does AccountsOS support?

AccountsOS is live in 21 countries as of June 2026: the UK, Ireland, Bulgaria, the UAE, Australia, the US, Hong Kong, Turkey, the Isle of Man, Guernsey, Germany, Denmark, Singapore, the Netherlands, Sweden, India, Switzerland, Canada, Austria, Norway and New Zealand.

Which countries were added in 2026?

Nine countries were added during 2026: Singapore, the Netherlands, Sweden, India, Switzerland, Canada, Austria, Norway and New Zealand, taking the total from twelve to twenty-one.

Does adding a country cost extra?

No. There is no per-country surcharge. Every supported country is included on every plan, and one subscription covers all the companies you run across them.
