When you cannot pay national taxes by the due date: an overview of the deferment of realization and the deferment of tax paymentThere is a system that lets you wait when you cannot pay tax right away

When national taxes cannot be paid in one sum by the due date, a deferment of payment may be granted on application to the tax office if certain requirements are met. The National Tax Agency explains the "deferment of realization", which holds off the seizure and sale of assets, and the "deferment of tax payment", which is based on grounds such as disaster, illness, closure of a business or a significant loss. Even when a deferment is granted, the treatment of delinquent tax (the charge corresponding to interest) is involved, so it is recommended to consult the collection section of the tax office with jurisdiction before the due date approaches.

Differences between the deferment of realization and the deferment of tax payment (overview)
Deferment of realizationDeferment of tax payment
Main groundsPaying in one sum would be likely to make it difficult to continue the business or maintain livingDisaster, illness, closure or suspension of the business, a significant business loss and so on
Guide to when to applyWithin 6 months of the due date and so onEarly, after the facts constituting the grounds have arisen
Deferment periodIn principle within one year (extension up to two years at most)Depends on individual circumstances (check the National Tax Agency's guidance)
How payment is madePaid in monthly installments during the deferment periodPaid in accordance with the terms of the deferment

Key points

  • When national taxes cannot be paid in one sum, there is a system under which payment is deferred on application to the tax office if the requirements are met (National Tax Agency No. 9206)
  • The deferment of realization has requirements such as that paying the tax in one sum would be likely to make it difficult to continue the business or maintain living. One requirement is that the application is made within 6 months of the due date
  • The period of a deferment of realization is in principle within one year, and the deferred tax is paid in monthly installments during that period. If there are unavoidable circumstances, it may be extended, together with the original period, to a maximum of two years
  • The deferment of tax payment requires facts such as disaster, illness, closure or suspension of the business, or a significant business loss. Its feature is that delinquent tax during the deferment period is exempted or reduced
  • Delinquent tax arises from the day after the due date, so consult the collection section of the tax office with jurisdiction as early as possible. The application is made by submitting the application form and a statement of the state of assets and income, and can also be done through e-Tax
Who is affected: Sole proprietors and owners of small and medium-sized companies who find it difficult, owing to funding circumstances, to pay corporation tax, withholding income tax, income tax on a final return, consumption tax and so on

What to do in practice

  • Confirm the due date and the amount payable, and check in your cash flow table the expected effect of the payment on your balance
  • Before the due date, consult the collection section of the tax office with jurisdiction, for example by phone, and confirm the necessary documents (application form, statement of assets and income and so on)
  • If a deferment is granted, keep making the set installment payments without fail
Note: This article is a general explanation based on the National Tax Agency's guidance. The requirements, periods, security and treatment of delinquent tax differ with individual circumstances and depend on the tax office's judgment. For the specific procedure, please consult the tax office with jurisdiction or a tax accountant.

The rule is to pay tax by a set day, but when you are ill, there is a disaster, or your shop is struggling, you may not be able to pay all of it right away. For such times, if you tell the tax office, there is a system that lets you wait on the time of payment or pay in parts. Even while you are waiting, the tax charged for the late part keeps growing, so once you know you cannot pay, it is important to consult the tax office early.

What to do once you know you cannot pay
  1. 1. CheckCheck the due date, the amount to pay, and when you will be able to pay
  2. 2. ConsultBefore the deadline, contact the collection section of the tax office
  3. 3. ApplySubmit the necessary documents and apply for a deferment

Points

  • Once you know you cannot pay, consult the tax office before the deadline arrives
  • If you meet the conditions, you may be allowed to wait on the time of payment or to pay in parts every month
  • Tax is charged on the late part according to the number of days late, so consulting early matters
For example: When you will not be able to hand in your homework by the due date, telling the teacher about it beforehand can sometimes get you more time. With tax too, it is easier to be listened to if you consult beforehand rather than after the deadline has passed.
