I recently received a notice from my local municipality tax office stating that I did not declare income on a side job I did for a university last year. Said university paid the salary (about 220,000 yen) into my bank account without deducting any income tax. I have to visit the city hall and report the income, which will then be added to my residential and health insurance taxes for this year, I assume?
My main question is whether I have to file my entire tax return again, supplying all the documents needed for tax deductions such as health insurance payments, etc. or is it not necessary since I reported everything on e-tax for 2024, excepting of course the side job?
