This article is based on the National Tax Agency's procedural guidance and interpretive circulars, and on Tokyo Shoko Research's survey of business closures and dissolutions. How you wind a business down varies greatly with your debts and the form of the company. If insolvency or an inability to repay is likely, consult a lawyer or tax accountant before proceeding on your own judgement.
This is an English translation of our Japanese article. The Japanese version and the documents published by Japan's National Tax Agency are authoritative. How a closure should proceed depends heavily on the company's debts. If the company is insolvent or cannot repay in full, consult a lawyer before following any of this.
Last updated: 5 September 2026. Based on the National Tax Agency's procedural guidance and interpretive circulars, and Tokyo Shoko Research's survey of business closures and dissolutions.
The short answer. The thing most often missed when winding up a Japanese company is the final filing deadline. Corporate tax and consumption tax are normally due two months after the fiscal year ends. But the return for the year in which residual assets are determined is due one month from the day after determination, and the extension that applies to ordinary returns is not available. Second, a company closing after years of losses may be able to use expired loss carryforwards — losses written off after the carryforward period, usable only in liquidation. This article walks through closing a kabushiki kaisha from dissolution to completion of liquidation, organised around the tax deadlines.
Closures are rising — and not because firms are failing
Tokyo Shoko Research counted 67,210 business closures and dissolutions in 2025, a record and the third consecutive year of records. The average age of the owner at closure was 71.5, the fifth straight year in the seventies.
The number to sit with is 52.8% profitable. More than half of the companies that closed posted a profit in their final accounts. Bankruptcy and closure are different things. Bankruptcy is running out of the ability to pay; closure is the owner deciding to stop. No successor, no more energy, a wish to end on one's own terms — closing while still in the black is increasingly common.
That is exactly why the tax procedure matters. In bankruptcy a court and a trustee take over. When you close voluntarily, you run the filings and registrations yourself, from dissolution through to completion of liquidation. Miss a deadline and penalty and late-payment taxes eat into what is left at the very end.
From dissolution to completion of liquidation
The key point is that dissolution is not the end. Dissolving only resolves to stop trading. What follows is liquidation: realising assets, paying debts and distributing the remainder to shareholders. The company disappears only when liquidation is completed.
- Shareholders resolve to dissolve (special resolution)A liquidator is appointed at the same time. In most small companies the existing representative director becomes the liquidator.
- Register the dissolution and the liquidatorWithin two weeks of dissolution (Legal Affairs Bureau)The registry then records the company as dissolved.
- File change notifications with the tax officesNational, prefectural and municipal. Separate filings are needed with the pension office, the labour standards office and Hello Work, and some social and labour insurance deadlines run in days, not months. If you have employees, this comes first.
- Public notice and individual notice to creditorsA claim period of at least two monthsNo distribution to shareholders is possible until it ends. This is why liquidation takes at least two months.
- File for the dissolution fiscal yearNormally within two months of dissolutionThe period from the start of the fiscal year to the date of dissolution forms one fiscal year.
- File for each liquidation fiscal yearWithin two months of each year endLiquidation fiscal years run in one-year periods from the day after dissolution. If liquidation finishes inside a year, this filing may not arise.
- Determine residual assets and file the final returnWithin one month of determination — no extensionThis is the trap; see below.
- Distribute the residual assetsAnything above the stated capital is treated as a deemed dividend and taxed in the shareholder's hands.
- Register completion of liquidationThe company now leaves the registry.
The trap: the last return is due in one month and cannot be extended
Corporate tax returns are normally due two months after the fiscal year ends, and an extension can be applied for where, for example, the articles fix the timing of the shareholders' meeting.
The end of liquidation is treated differently. The National Tax Agency sets it out as follows.
Liquidation fiscal years run in one-year periods from the day after dissolution. The return for the fiscal year in which residual assets are determined is due within one month from the day after determination, and the extension does not apply.
Summarised from NTA interpretive material. For consumption tax as well, where residual assets are determined during liquidation, the return and payment are due within one month from the day after the end of the taxable period in which determination falls.
| Return | Deadline | Extension |
|---|---|---|
| Ordinary fiscal year | Two months after year end | Sometimes available |
| Dissolution fiscal year | Two months after dissolution | Sometimes available |
| Liquidation fiscal year | Two months after each year end | Sometimes available |
| Year residual assets are determined | One month after determination | Not available |
One month is shorter than it sounds. Accounts must be closed, the return prepared and the tax paid. Distribute first and the money to pay the tax may no longer be in the company. Decide the determination date only after you have planned the accounts, the return and the payment — that is the practical rule.
Relief for loss-making companies: expired loss carryforwards
Blue-return loss carryforwards expire after a set number of years. Losses past that point are expired loss carryforwards.
In liquidation only, they can be deducted (Corporation Tax Act, Article 59(4)). The reason is simple: liquidation tends to generate profits because assets carrying unrealised gains get sold. A company that lost money for years can post a large profit in the year it sells its land or building — and face a hefty tax bill on the way out. This rule prevents that.
| Item | Detail |
|---|---|
| When it applies | A dissolved company where no residual assets are expected |
| What that means | Insolvency at the end of the fiscal year |
| How it is checked | Generally via an economic balance sheet — assets and liabilities at market value |
| When it is judged | By the circumstances at the end of each liquidation fiscal year |
| Cap | Income remaining after deducting blue-return losses |
Organised from the NTA's Q&A on determining "when no residual assets are expected" under Article 59(4).
The point is that it is judged year by year. A company insolvent at dissolution that clears its debts by selling assets may no longer be insolvent at that year end — and cannot use the relief for that year. The reverse also happens. You cannot judge without an economic balance sheet, so assets and liabilities need restating at market value before liquidation begins. This is where a tax accountant becomes effectively unavoidable.
Distributing what is left creates a deemed dividend
Once debts are paid, the remainder goes to shareholders — and the part exceeding the stated capital is treated as a dividend and taxed in the shareholder's hands. That is the deemed dividend.
In a one-person company where the owner is the shareholder, money coming back after liquidation is taxed as dividend income. What is left in the company does not simply become yours.
In practice, a director's retirement allowance at a reasonable level is often paid before liquidation so that it is received as retirement income, which benefits from the retirement income deduction and the halving of the taxable amount. Any part that is unreasonably high, however, is not deductible for the company.
Closing the business is a qualifying event under the Small Enterprise Mutual Aid scheme. Payouts are generally treated as retirement income, which keeps the tax down. See the tax benefits of the Small Enterprise Mutual Aid.
Closing a sole proprietorship is mostly notifications
There is no registration and no liquidation procedure — the work is filing with the tax office.
| Filing | Deadline |
|---|---|
| Notification of opening or closing a sole proprietorship | By the income tax filing deadline for the year of closure |
| Notification of discontinuing blue-return filing | By the filing deadline for the year concerned |
| Notification of business discontinuation (consumption tax) | Promptly once it arises |
| Notification of closing a salary-paying office | Where you paid salaries |
| Application to reduce estimated tax prepayments | Where income will fall |
This deadline has changed. It used to be within one month of closing. From 1 January 2026 it is the income tax filing deadline for the year in which the closure falls. A great deal of published guidance still says "within one month", so check the NTA's current page.
Also worth knowing is the special rule for necessary expenses after ceasing business (Income Tax Act, Article 63). Costs that arise after closing — restoring an office to its original state, expenses finalised later — can in principle still be treated as necessary expenses. Closing does not automatically mean the cost is lost.
For closing a sole proprietorship and returning to employment, see the guide to going from sole proprietor back to employee.
Worth considering before you close
| Option | When it fits |
|---|---|
| Succession or sale to a third party | Profitable, with value in customers, staff or licences |
| Dormancy (keeping the registration) | You may restart. Note that per-capita local tax can still apply and filing duties remain |
| Liquidation (this article) | No successor and the decision to stop is settled |
| Formal insolvency proceedings | Debts cannot be repaid. Go to a lawyer |
Given that more than half of closing companies are profitable, looking for a buyer first is worth the effort. Japan's business succession support centres operate nationwide and consultations are free. On the tax side, see the business succession tax regime.
If the company is insolvent or repayment is not realistic, do not follow the steps in this article. Ordinary liquidation assumes every debt can be paid. Otherwise the route is special liquidation or bankruptcy, and the first step is a lawyer. The longer the decision is postponed, the fewer options remain.
What to do today
- Restate assets and liabilities at market value from your latest accounts. Whether you are insolvent determines both whether expired losses are usable and whether ordinary liquidation is possible at all.
- If you have employees, check the social and labour insurance deadlines first. Some are shorter than the tax ones and delays affect your staff.
- Work backwards from the return and the payment when setting the determination date. The final return is due in one month with no extension. Secure the tax money before distributing.
Frequently asked questions
Does the company cease to exist on dissolution?
No. Dissolution is the resolution to stop trading; liquidation then follows, realising assets, paying debts and distributing the remainder. The company leaves the registry only on completion of liquidation. Because the public notice to creditors requires a claim period of at least two months, the process takes at least that long.
Which deadline matters most during liquidation?
The return for the fiscal year in which residual assets are determined. It is due within one month from the day after determination, and the extension available for ordinary returns does not apply. Consumption tax is the same one month. Plan the accounts, the return and the payment before fixing the determination date.
Can losses more than ten years old be used in liquidation?
Yes, if the conditions are met. Expired loss carryforwards can be deducted by a dissolved company when no residual assets are expected (Corporation Tax Act, Article 59(4)). Insolvency at the end of the fiscal year satisfies that, judged generally on an economic balance sheet at market value. Because it is judged at each liquidation year end, availability can change from year to year.
Can I simply take the money left in the company?
Not simply. The part of a distribution exceeding the stated capital is a deemed dividend, taxed as dividend income in the shareholder's hands — including in a one-person company where the owner is the shareholder. In practice a reasonable director's retirement allowance is often paid before liquidation so it is received as retirement income, but any unreasonably high portion is not deductible.
When is the sole proprietorship closure notification due?
From 1 January 2026 it is due by the income tax filing deadline for the year in which the closure falls. It used to be within one month of closing. A lot of guidance still says "within one month", so check the NTA's current page. The notification to discontinue blue-return filing is likewise due by that year's filing deadline.
Does the same process apply if debts cannot be repaid?
No. Ordinary liquidation assumes all debts can be paid. If they cannot, the route is special liquidation or bankruptcy, and the first step is to consult a lawyer. Delaying the decision steadily removes options, so early advice usually limits the damage.

This article is general information about Japanese tax and corporate procedures and does not determine any individual case. How a closure proceeds depends on debts, shareholders and licences. Confirm with the tax office, Legal Affairs Bureau and pension office, and consult a tax accountant, lawyer or judicial scrivener. Where debts cannot be repaid, formal insolvency proceedings — not liquidation — are what needs considering.
