Imagine a tax noob were to receive unemployment benefits for a few months in early 2020, based a % of previously received IV Taggelder income (so no general pension contributions). Say around 20k was taxable out of around 23k. At the same time an IV pension was pending, but seemingly unlikely. When the IV pension was approved in late 2021, the Arbeitslosenkasse understandably demanded the return of said money, but ultimately could only recover from this individual's general pension (from work contributions), which didn't exist. Proof was provided from the relevant office, and that was that.
Or was it?
Say this person then received a new Bescheinigung from the Arbeitslosenkasse for 2021, in January 2022, showing the same amount received and taxable from the 2020 Bescheinigung. Confused, they decide to ignore it for a few months, while postponing 2021's filing until later this year.
Say this person recently decided to call them and ask what's up, and their attention was directed to the minus sign following the amounts (this hypothetical person was more accustomed to seeing a minus sign before a number. What an r word!).
Essentially, it's as if they retroactively didn't receive the 23k, at least for tax purposes, notwithstanding the non-paying-back part. The Arbeitslosenkasse told them they should be eligible for a refund, as crazy as that sounds.
So, finally, what if then the Gemeinde's tax office insists on the 30 days deadline to challenge an accepted declaration, which naturally preceded the adjustment nullifying the amount? Instead of adjusting 2020's filing, which they insist is impossible due to these 30 days, despite the limitations of linear time, are they meant to declare negative 20k for 2021? lol? Write to the Kantonal office? And expect a different response? Should they simply disregard the potential tax windfall, and be happy they didn't have to pay back the 23k? (not that they could have). Imagine that without that 20k (which is now void) no tax liability at all would have accrued in 2020 (imagine other taxable income less than 10k, hypothetically).
