According to the local the threshold for share gains is 3 million kr, about 300 thousand USD. You only pay the exit tax on amounts above that.
"Those subject to the tax will have to address their tax obligations related to gains exceeding 3 million kroner on shares acquired during their time in Norway.
They will have several options to fulfil this obligation, including immediate payment, interest-free instalments spread over 12 years, or deferred payment with accrued interest.
The changes are part of the government's efforts to counter the recent outflow of wealth from Norway, with Switzerland being a popular destination for tax exiles."
