For the federal states, the real estate transfer tax is a bubbling source of money, for private house buyers it is an increasingly heavy additional burden: If a developed or undeveloped property is sold, the extra special tax is due. 16 billion euros according to the Federal Statistical Office, came into the coffers of the federal states in 2020 – more than ever before. Buyers already have to save for an average of four years just for the real estate transfer tax alone, as one shows examination of the German Economic Institute (IW). And should residential real estate prices continue to rise, buyers will have to put even more tax on the table in the future. But a small passage in the coalition agreement by SPD, Greens and FDP gives hope.
