Japan's Refundable Tax Credit Starts in FY2029 — the Registration Rate for the Public Benefit Account It Rests On Is About 50%, and the Rest Still Need Their Consent Confirmed

On 5 August 2026 the government adopted by cabinet decision a basic policy on introducing a refundable tax credit, following the interim report of the National Council on Social Security of 29 July 2026[1].

Five days later, the first session of the forum for consultation between national and local government was held. Municipalities set out the weight of the administrative work; the state set out measures to lighten it.

This piece reads, from the cabinet decision itself, what that work consists of.

Who qualifies

The policy has two aims: lightening the burden on middle and lower income working-age people so that take-home pay rises with income, and easing the restraint on working hours caused by the so-called income walls.

The conditions read as follows. The benefit targets those with a certain level of earned income and a certain level of tax and social insurance contributions. Earned income covers business income and employment income and, in view of the diversity of modern work, miscellaneous business income, so sole traders and freelancers qualify[1].

The unit is the individual, and single people qualify[1]. It looks at one person at a time rather than a household.

The amount rises, flattens, then disappears

How the amount is set is written down. To encourage work, the benefit rises as earned income rises up to a certain level, then becomes flat. Where total income exceeds a set amount, it tapers and disappears, for reasons of fairness[1].

A rising section, a flat section, then a section where it fades out.

There is a child addition. For those supporting children, an addition is made according to the number of children aged 18 or under[1].

Only the bottom does not rise

One exception sits at the lower end.

Because income below the tax-free threshold presents difficulties of capture, and raising the benefit in that range could lead to incorrect payment, the amount is fixed there[1].

Because income cannot be captured, the part that rewards working more does not apply to the lowest band. In a scheme built to encourage work, the lowest income range is the one left off that slope.

The amounts have not been set

How much will be paid is not in this document. The income threshold for the benefit is to be considered alongside securing permanent funding, with reference to international comparisons of net burden rates and to the income ranges covered by similar schemes abroad[1]. The same wording covers the benefit amount.

The frame comes first; the amounts come later, with the money to pay for them.

The document says why FY2029

Why full introduction waits until FY2029 is set out.

Because additional means of securing information are needed, including identifying high-income spouses for reasons of fairness and capturing information on dependants aged 16 to 18 in support of households raising children, full introduction comes in FY2029, the year by which the necessary groundwork is expected to be in place[1].

What is being waited for is not budget or legislation but information. How much a person's spouse earns, and how many dependants aged 16 to 18 there are. No mechanism currently lets the administration confirm either.

The 16-to-18 band is named because under-16s are covered by the child allowance, so that information is already held.

The bridge years run on the information already held

The two intervening years take this shape.

For two years from 1 April 2027, the consumption tax rate on food and drink covered by the reduced rate falls to 1%. Alongside it, a benefit drawing on income information currently held by public bodies is introduced in FY2027, within the value of that 1% of consumption tax on food and drink[1]. Together the two bring the effective rate on food and drink to zero.

The bridge differs from the full scheme. There is no exception taking spousal income into account, and the addition for children aged 18 or under is replaced by an addition for children aged 15 or under[1].

Households with a child aged 16 to 18 fall outside the addition for those two years. The stated reason is that the information does not exist.

The work is confirming intent and collecting account details

What is at issue between national and local government is also written down.

To lighten the load on the bodies delivering the scheme, the state will take the lead, with measures addressing what proved heaviest in past benefit administration: confirming recipients' intent to receive and their account details, and handling external enquiries[1].

The weight of paying a benefit is not in calculating the amount. It comes after the list of recipients is settled: confirming that each of them wants the money, and collecting somewhere to send it. That is where past payment rounds jammed.

The figure the machinery rests on is 50%

The proposed way through is the public benefit account.

On the public benefit account in particular, the state will push hard to raise a registration rate that currently stands at around 50%, will make its use the rule for receiving this benefit, and will continue work on accuracy of account details and related functions[1].

Registration is at 50%. Where an account is registered, payment can go out without confirming intent. Where it is not, the confirmation remains.

Which means the foundation this scheme is about to stand on is half built. How much of the remaining half is filled in before the FY2027 advance benefit decides how much work stays with municipalities.

The line is drawn at systems for the state, counters for municipalities

The direction of the split is given. Rather than an either/or between the state and municipalities, the two will run the scheme together, minimising the administrative burden across the country as a whole; nationally uniform infrastructure such as systems is in principle to be built by the state, while the interface with residents is to sit mainly with municipalities[1].

Systems to the state, contact with residents to municipalities. And as set out above, the weight sits on the side of contact with residents. What the state takes on is consideration of a national call centre and measures to lighten the burden of confirming intent to receive[1].

The split is not fixed either. The division of roles between national and local government is recognised as liable to change, and consideration between them continues after the scheme begins[1].

The government names the people who fall outside

The scheme conditions eligibility on earned income. Anyone not working is, by construction, outside it.

The document says so itself.

Those working but on low incomes, and those willing to work but unable to because of illness or disability, are to be identified carefully where they fall outside the benefit and need support; the relationship with existing schemes including self-reliance support for the needy and disability welfare is to be worked out, and the necessary approach, including delivering benefits together with consultation and employment support, is to be considered along with its funding[1]. A conclusion is to be reached by the time of full introduction.

The scheme named as the catcher is self-reliance support for the needy.

As 3.456 million consultations over ten years of support for the needy（このサイトの記事） showed, that scheme turns one consultation in four into a continuing support plan, and the employment preparation service whose effect is measurable is used by 6.1% of those with a plan. That is where people falling outside the new benefit are to be sent.

Regular employment among the ice age generation rose by 110,000 in five years（このサイトの記事） showed the same shape: the non-labour-force population fell by 360,000 while those neither working nor studying rose by 30,000. Schemes reach the people closest to work first, and the rest stay where they are.

What has to be counted before the next decision

The figures for this scheme have yet to be created. Two of them should be settled in advance.

The first is when, and among whom, the public benefit account registration rate rises. A single national figure of 50% does not show where the people needing confirmation are concentrated. Whether they are mostly older, or mostly people whose registered address differs from where they live, changes the shape of the work left with municipalities.

The second is how many people fall outside. How many come in below the earned income threshold, and how many of those reach self-reliance support for the needy or disability welfare. Without that, the review promised for FY2029 has nothing to work with.

As designing outcome indicators（このサイトの記事） sets out, what counts as a result has to be settled before a scheme starts running. There are three years.
