The woman had gained clearance from Swedbank, who held her 23,000 kronor ($3,150) pensions saving but the tax agency has said that no exception can be made for the woman despite the fact that her doctors have said she won't live until pension age.
The tax agency ruled in a decision last month that there exist "no clear reasons" for making an exception in order to allow the woman to take her children, 10 and 13-years-old on a last family holiday camping in Denmark.
"I was surprised. Is a deadly illness not sufficient reason," the woman told the Svenska Dagbladet daily.
The woman appealed the tax agency's decision to the administrative court which ruled in her favour but the tax agency stood its ground and appealed the lower court decision to the Administrative Court of Appeal (Kammarrätten) which found in favour of the woman.
Despite the court decision the tax agency is still refusing to allow her access to her savings and is considering whether to appeal to the Supreme Administrative Court (Regeringsrätten).
