## Key Changes for High-Income Individuals
The FY2026 tax reform package introduced sweeping changes to **top-tier income taxation** and deductions:
- **Base income threshold for special high income deduction dropped** from JPY 330 million to **JPY 165 million**, while the associated tax rate increased from 22.5% to **30%**. This affects extremely high-income individuals.([mof.go.jp](https://www.mof.go.jp/tax_policy/tax_reform/outline/fy2026/08taikou_gaiyou.htm?utm_source=openai))
- **Basic (standard) deduction** increased for those with total income ≤ JPY 23.5 million; deduction for employment income minimum raised from JPY 650,000 to JPY 690,000. This aims to help lower & middle income groups.([mof.go.jp](https://www.mof.go.jp/tax_policy/tax_reform/outline/fy2026/08taikou_gaiyou.htm?utm_source=openai))
- **One-parent deduction (ひとり親控除)** expanded: income tax allowance increased from JPY 350,000 to **JPY 380,000**, resident tax from JPY 300,000 to **JPY 330,000**.([mof.go.jp](https://www.mof.go.jp/tax_policy/tax_reform/outline/fy2026/08taikou_gaiyou.htm?utm_source=openai))
## Planning Opportunities & Caution Areas
### Income Restructuring & Timing
- If you expect your year-end income to cross the **JPY 165 million threshold**, consider **accelerating deductions** or distributing income across tax years where possible.
- Review bonus timing or income recognition, where allowable under accounting & tax law, to avoid crossing higher brackets.
### Optimizing Deductions
- For those eligible, **配偶者控除 (spousal deduction)** / **扶養控除 (dependent deduction)** still relevant; ensure dependents satisfy residence rules by Dec 31 or relevant cut-off dates.
- Evaluate eligibility for itemized deductions—insurance, medical expenses, social insurance; prepaying or deferring payments that align with deduction eligibility can be helpful.
### Use of Investment Accounts
- **NISA expansions** (for minors especially): non-taxable investment accounts now opened from ages 0-17, improving opportunities to shift income-generating investments.([mof.go.jp](https://www.mof.go.jp/tax_policy/tax_reform/outline/fy2026/08taikou_gaiyou.htm?utm_source=openai))
## Behavioral Shifts to Watch Out For
- **Loss of formerly generous high-income thresholds** raises risk of high marginal tax rate exposure; salary packaging & compensation structure reviews are crucial.
- **Tax residency & source income** become more material for non-resident or frequently traveling individuals.
- **Audit & documentation risk** increases around income attribution and thresholds—especially with global or foreign income.
## Examples
| Scenario | Pre-2026 | After Reform |
|----------|-----------|---------------|
| CEO earning JPY 200 million salary + bonuses | Previously benefited from higher special deduction base at 330M threshold | Now subject to 30% rate at 165M threshold; lost deduction cushion—effective marginal rate increases significantly |
| Parent with young dependents, modest income | Could claim spousal & dependent deductions using existing thresholds | Now higher deduction amounts provide more relief—evaluate whether household income distribution can maximize deductions |
## Actionable Checklist
1. Project full-year income early; model impact of higher rate threshold.
2. Maximize any deductible spending that can be accelerated or carried into qualifying periods.
3. Consider shifting investment income into NISA accounts where possible.
4. Engage a tax advisor to evaluate international income exposure, residency planning, and documentation for deductions and exemptions.
High incomes are now more visible to tax authorities—legal planning matters more than ever.
