(Never cheat or lie to the tax authority – Heavy Penalty for cheating)

Possible price for cheating or lying to the tax authority can be very expensive. Especially cheating your income by hiding your revenue will probably cost very expensive consequences.

Hiding revenue is to be regarded as “intentional”, and therefore it will be subject to “Heavy Penalty”, which is 35-40% of the tax you try to avoid.

As to the expenses, as long as you think it is necessary or related to your business, it can be widely accepted. Meeting with your friend for business advice or possible business development may probably be accepted as a justifiable expense.

Even if it is not accepted, you will not be regarded you cheated, because it should be a just difference in view, unless it is too extreme and aggressive.

(File tax on time, and pay the tax later, if cash flow situation does not allow)

The penalty for missing the deadline to file is very heavy. Even missing one day of the deadline will be 15-20% of its own tax.
if the consumption tax is 5,000,000 yen and the cost of missing the deadline by one day will be 1,00,000 yen.

It may be ok to delay payment of the tax, if your cash flow does not allow, because the penalty is only interest by annual rate of 1.8%. But a failure in filing by the deadline is very costly.


A mistake in accounting is usually to fall in this category. For example, personal meal or shopping are usually to be categorized into this group. A TV set in home is a typical example. Unless the amount is huge, the tax authority will not regard them as intentional and therefore charge the heavier penalty (of 35-40%).

(Be imaginative and consult with your tax accountant)

Tax law is a law, which cannot cover every single situation in the real world. By exploring possible combination of tax structure, that you think will probably save your tax, consult your tax accountant. He might not be able provide you many new tax structure, but he should be able give you his feedback of rather positive or no.
