Selling car after operational leasing

Hello,

My operational car leasing will finish in December.

Now after the car will be transferred on my name, someone told me I will not be able to sell the car in the next 5 years without paying a high tax. And recommends me to rather sell the leasing while the contract is still running to get the full value of the car. My final payment is very low, so my initial idea was to keep the car for another 6 months or so and then sell it, but this may changes because of the tax.

I can't find any information on this tax. Can someone show me or explain how this tax works and how high it is?

Thank you

You are right about the tax. Translation:

"Until the end of 2021, Polish people / business persons were in a rather privileged position because they could sell the purchased cars without having to pay taxes after 6 months - important, this period was counted from the end of the month of purchase. After the changes, i.e. after January 1, 2022, the owner must wait not 6 months, but 6 years to avoid tax. Importantly, its amount is calculated based on the market value of the car."
