Loss carryforward for study in the country if you have lived abroad
I started a further education measure (Master of Business Administration) in Germany in 2018, but was still working in Austria at that time. In 2019, I moved to Germany and wanted to claim a loss carryforward for the year 2018 for the already applied study and deduct it with my tax return for 2019. Now the tax office told me that I cannot claim a loss carryforward for 2018, as I worked and lived in Austria. I was employed by the United Nations in Austria (so exempt from income tax). This might play a role. I have heard from various sources that it is possible to claim a loss carryforward even for the year 2018. Am I correct in my assumption or is the tax office's response correct that I am not allowed to claim a loss carryforward?
