Japan's FY2026 Tax Reform: The Key Points
Approved by the Cabinet in December 2025, Japan's FY2026 tax reform outline centers on responding to rising prices and supporting economic growth, with a wide range of revisions. This article organizes the points most relevant to business owners and households, translating the jargon into plain language.
- The big picture of the FY2026 reform and its three pillars
- The inflation-linked basic deduction and its effect on the "income wall"
- A new incentive for large-scale capital investment
- Revisions affecting inheritance, gifts and SMEs
01The big picture of the FY2026 tax reform
A tax reform outline is the "blueprint" for how the tax system will be revised from the next fiscal year onward. The ruling party decides it each December, and the law is then amended in the ordinary Diet session the following year. The FY2026 outline is built largely around responding to prolonged price increases and encouraging domestic investment and wage rises.
From a business owner's viewpoint, three pillars are worth keeping in mind.
- Responding to inflation (raising the basic deduction and the like)
- Promoting growth investment (incentives for capital investment)
- Revisions to asset taxation and SME-related measures
02Responding to inflation — the basic deduction and the "income wall"
A mechanism to raise the income-tax basic deduction and similar figures in line with price increases is under consideration. Alongside this, the additional basic deduction for those below a certain income level is set to be expanded, and a special measure to raise the minimum guaranteed employment-income deduction is expected.
This also addresses the so-called "income wall" — where part-time workers hold back their hours out of concern that "take-home pay falls once income exceeds a certain level". Raising the deductions pushes taxable income down for the same way of working.
03Promoting growth investment — incentives for capital investment
To raise productivity, a new incentive is expected that lets companies choose, for large-scale capital investment, between "immediate depreciation" and a "tax credit". Immediate depreciation — expensing the cost in the year the equipment is acquired — helps cash flow, while a tax credit directly reduces the tax due.
| Type of incentive | Effect | Suits the case where... |
|---|---|---|
| Immediate depreciation | Deduct the full acquisition cost in the year of acquisition | You want to compress current profit and thicken cash on hand |
| Tax credit | Deduct a set percentage of the cost directly from corporate tax | You want to reduce total tax over the long term |
For companies weighing a large investment, this is an important change that can affect the timing of execution. We dig deeper in the related article "New Tax Incentive for Large Capital Investment".
04Revisions affecting inheritance, gifts and SMEs
In asset taxation, the reform includes a review of how rental real estate is valued for inheritance tax. If you own rental property, we recommend checking the impact early, as the assessed value may change.
For SMEs, discussion is progressing toward continuing and expanding the wage-increase promotion tax measures and business-succession-related provisions. It's worth taking stock, at closing time, of whether any scheme could apply to your company.
Summary
Japan's FY2026 tax reform rests on three pillars: responding to inflation, promoting investment, and revising asset-tax and SME measures.
Raising the basic deduction affects how people work, the investment incentive affects investment decisions, and the property-valuation review affects inheritance planning.
Because the outline is still a policy stage, confirming the finalized requirements and timing before acting is essential. If a change affects your company, consult a specialist early.
