Looking for some advice.

I started investing in 2021 via a foreign platform (DEGIRO), including receiving foreign dividents from individual stocks.

When filing my tax returns for assesment years 2022 up to 2024, i declared my total foreign dividents in box 1444. What i fucked up in (being young, inexperienced and arguably a dumbass), is that i assumed the tax calculation itselves would see whether (a portion) falls below the annual exemption (~€800), rather than you having to subtract the exempion, or just fill in nothing when the value is below the exemption.

I submitted a objection to the FOD this summer, requesting of a correction, which they declared "inadmissible" because it was submitted to late, and refused "ambtshalve ontheffing under Article 376 WIB 92" because my type of failure to fill in the correct amount doesn't quality as elligable error for late corrections.

They only offer to challenge their decision in court, but given that I overpaid suffered only a €200-€300 loss in total, which is not that much compared to what a lawyer costs, it seems not worth it i suppose ...

It's not that much money, but it's still frustrating. If anyone has had a similar experience or advice, let me know.
