The June 30 deadline has passed. But the riskiest part of the year is still ahead.
If you're a resident of Japan with overseas assets above ¥50 million — or with high income or net worth — June 30 was the filing date for the Overseas Assets Report (国外財産調書) and the Assets & Liabilities Report (財産債務調書).
Here's what many people miss: individual tax audits in Japan tend to cluster in autumn. The National Tax Agency's year resets in July, and by September the examinations are underway.
That gap — right now — is your window.
Filing or correcting *voluntarily*, before any audit notice, is the single biggest lever you have on penalties. A voluntary late filing can cut the non-filing additional tax to 5%, and proper disclosure moves the overseas-asset penalty adjustment in your favour instead of against you.
So use the summer to get your status clear:
• Did you actually have a filing obligation this year?
• Does what you filed match reality — including overseas holdings?
• Are there gaps worth fixing on your own terms?
Better to answer those now than across a desk from an examiner in November.
If you'd like a quiet second look before audit season, that's exactly what we do.
