If you're not comfortable committing a few million: don't. Just partner with a Banking-as-a-Service provider like Modulr, OpenPayd, or Intergiro if all you want to do is build a good product.
The bare costs might just be a few hundred thousand
in theory, but most regulators expect to see a capital commitment of a few million or they will be very hesitant to issue a license. Issuing a license is a lot of upfront and ongoing work for a regulator. You pose an economic, regulatory, and reputational risk. Regulators don't want to issue license to someone who's going to fail and cause a mess, or someone who knowingly or inadvertently becomes a laundromat for criminals.
If you have a few million, then look at jurisdictions less form a cost perspective and more from a suitability perspective. Who are your customers? What do they do? Why are you targeting them?
Liechtenstein is interesting, but I'm not sure it's really fair to look at such a vague description as above and call Liechtenstein the best.
The focus in the description we got here is on cost and openness. I don't think Liechtenstein satisfies those two particularly well. It's a high-cost jurisdiction and a regulator that doesn't exactly exude a welcoming aura. They're not hostile, but they have a long way to go compared to most of their peers.
It's a strong banking jurisdiction but for fintech, it's practically unheard of. IIRC, it has lost more
EMI and PI licensees than it currently has active (four). And two of the current licensees subsidiaries/majority owned by
Swiss banks (Cornèr and Hypothekarbank Lenzburg).
Headline tax is generally not a concern when people start financial institutions. If it were, there wouldn't be huge fintech sectors in countries like
Germany, France, Netherlands, and
Spain. But if headline tax rate truly mattered much, why would anyone form an
EMI in Germany when they could go to Malta and simply passport the license? However, if headline tax rate is a major concern, you can get very similar or lower in for example Lithuania, Malta, Cyprus, and Ireland.
I'm not sure how one would even quantity speed of licensing Liechtenstein. If my memory is right, FMA has handled fewer than 10 total EMI and PI licenses in total. Compare that to the enormous numbers in Lithuania, Cyprus, Malta, Germany, France, Spain, Luxembourg, Netherlands. Yes, those places may have backlogs at times but at least the people there are experienced. You know what to expect. FMA might be fast — who knows? You're throwing yourself into the unknown.
I'm not saying Liechtenstein is bad. But I'd only pick Liechtenstein after carefully considering the business plan and how well it matches with FMA's expertise and experience. For a cookie cutter setup, I'd go with a place that has issued a couple of dozen licenses.
