Kazeishomeisho not showing 2nd income 2020

Will be applying to extend my spouse visa soon. I just got my kazei shomeisho �ېŏؖ� and noticed that it only shows the income of my main job in 2020 (about 2.5 mil yen). I got my first part-time job last year (which I have permission for) and earned about 600,000 yen from that (the part-time job took 10% income tax every month). Should I go back to city hall and tell them there should be extra on the kazei shomeisho ? Have to admit I'm clueless about all this. I have a �x�������� (Shiharai chōshū-sho) from the part-time gig.

If you have a second income exceeding a certain amount (I believe it is 200,000 yen in a year) you need to declare that income along with the taxes they already deducted. Otherwise the tax office does not know that you had that second income and that you�fd paid taxes on it.

There is a process called �gkakutei shinkoku,�h final tax filing, which you do in the spring for the previous year. The guide in English is here:

You might want to take the current tax statement and the extra paper you have (the one showing the additional income and tax withheld by your part-time job) to the local tax office, and see if you can do a tax filing now to correct the situation.
