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 and︀ ongoing work for a regulator. You pose an economic, regulatory, and reputational risk. Regulators don't︁ want to issue license to someone who's going to fail and cause a mess, or︂ someone who knowingly or inadvertently becomes a laundromat for criminals.
If you have a few︃ million, then look at jurisdictions less form a cost perspective and more from a suitability︄ 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 vague︆ description as above and call Liechtenstein the best.
The focus in the description we got︇ 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're︉ not hostile, but they have a long way to go compared to most of their︊ peers.
It's a strong banking jurisdiction but for fintech, it's practically unheard of. IIRC, it︋ has lost more EMI and PI licensees than it currently has active (four). And two︌ of the current licensees subsidiaries/majority owned by Swiss banks (Cornèr and Hypothekarbank Lenzburg).
Headline tax︍ is generally not a concern when people start financial institutions. If it were, there wouldn't︎ be huge fintech sectors in countries like Germany, France, Netherlands, and Spain. But if headline️ 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 the︀ people there are experienced. You know what to expect. FMA might be fast , who︁ knows? You're throwing yourself into the unknown.
I'm not saying Liechtenstein is bad. But I'd︂ only pick Liechtenstein after carefully considering the business plan and how well it matches with︃ FMA's expertise and experience. For a cookie cutter setup, I'd go with a place that︄ has issued a couple of dozen licenses.
