Time limitations to selling a flat in Poland (bought a year ago)

Hi all,
I bought a flat in Warsaw with my Polish (now ex-)partner about a year ago. I am an EU citizen. Things didn't work out, and I'll be moving to Germany or France in a couple of months. We have co-ownership, 2/3 for me. My ex-partner doesn't earn enough to take charge of the whole mortgage. I would prefer to just sell the flat (or at least my share). But I heard that you can't sell a property too soon after buying without paying significant taxes. Is there any way to provide a "reason/excuse" for the selling? Such as moving abroad?

Thanks for any answers

Well that Capital gains tax would only be the case if you were making a profit on the sale - unlikely at the current market prices.

You will have to pay the stamp duty (or sort it out with a buyer) and the notary costs but that should not be a huge amount.

Ah, ok! Yes, I doubt we'd make a profit even if we wanted to. Great, thank you for your quick answer!

Yes, exactly. However, if there is any profit from such a sale made within 5 years from the original purchase of that property, the tax is 19%.
