How it works
- 0.7% of year-end loan balance is deducted from income tax (and partly resident tax) each year.
- 13 years (new homes from 2024 onwards) or 10 years (used homes / renovations).
- Maximum loan balance for deduction varies by energy efficiency: 5,000万 (premium) → 2,000万 (renovation).
- If income tax is fully offset, up to ¥97,500/year can be applied to resident tax.
Eligibility for foreign residents

First year filing
You must file a tax return (確定申告) in your first year, even if you're a regular employee. From year 2 onwards, employees can claim it through year-end adjustment (年末調整) using forms sent by the tax office.
