Do I need to file a Final Income Tax Return even though I haven’t lived in Japan 1 year yet?

1. If your annual income from January 1 to December 31 exceeds 200,000 yen, you are obliged to file an income tax return.

   Those who had no income (no income tax) are not obliged to file an income tax return (kakutei shinkoku) at the tax office. However, if you file an income tax return, the National Health Insurance tax for the following year will be reduced by a certain amount for households that had no income (households below a certain income level).

   In summary, you should file an income tax return regardless of your annual income.

   Every year, tax returns are filed between February 16 and March 15 of the following year for income generated during the year from January 1 to December 31.

   You may need to check a bit to see if it is kakutei shinkoku that your boss is talking about at this time of the year.
   If I am wrong, I am sorry.

2. >9th January 2023 to end of April, I worked in Ibaraki earning less than 200,000円.

   The “<¥200,000 income tax exemption” you speak of only applies to “side income”. Not “employment income”

   So first you will need to establish if this is “employment income” or not.

   That will determine if you can utilize the “<¥200,000 income tax exemption” or not and determine if you need to file a final tax return or not.

   So was this income “employment income”?

3. You say you had the 1st job by the end of April. But you started the 2nd one on March 16?

4. In addition to what the other comments are saying:

   You might be confusing what he is saying or he is saying it wrong, but if it came from your boss he probably means that you haven’t submitted your documents for year end adjustments. You should do this so they can calculate your taxes and finalize your tax payments for the year.

   If you do this you don’t have to file a tax return yourself unless you have other income that causes tax liabilities outside of your work income.
