That's incorrect based on my experience. The law exposes startup founders to large tax liabilities immediately after a financing. We've hired some of the top lawyers in Norway and the consensus is the only alternative is to relocate. There's plenty of articles about it in the Norwegian startup press.
Even better, you have to pay Norway on your unrealized capital gains but they won't credit you on future losses from the startup. Essentially they have socialized the profits and privatized the losses.
You are mixing two different taxes. The article is about the new exit tax. The other relevant tax is our wealth tax.
You don’t sound like a person who likes taxes much. In Norway they are very important since we have good infrastructure in most areas such as telecom, roads, trains, airports, electricity and water. We also have great healthcare. And lots of benefits for parents with children.
