Simplified Taxation Revocation Timing Simulator (Japan Consumption Tax)
Work out, for free, the earliest date and filing deadline for reverting to the standard consumption tax scheme after electing Japan's simplified taxation scheme. A simple calculation that reflects only the 2-year commitment.
What Is the Simplified Taxation Revocation Timing Simulator?
The Simplified Taxation Revocation Timing Simulator calculates the earliest date on which a business using Japan's simplified consumption tax scheme can file the "Simplified Taxation Election Revocation Notification" to revert to the standard scheme, along with the corresponding filing deadline. Just enter your election effective date, and the tool automatically calculates when the 2-year commitment ends.
The revocation notification comes with two separate constraints: the earliest period from which it can take effect, and the deadline by which you must file to hit that period. This tool calculates both at once, and if the deadline has already passed, it automatically shows you the next opportunity.
How to Use
- Enter the election effective date Select the first day of the first taxable period in which the simplified scheme applied after filing the election notification.
- Check your result See the earliest taxable period you can revoke from and the corresponding filing deadline.
Tips for getting more out of it
- The filing deadline is the day before the start of the taxable period you want to revoke from. Miss it by even one day, and you must remain on the simplified scheme for one more full taxable period before you can try again.
- The simplified taxation election carries only a 2-year commitment — unlike the Taxable Person Election Notification, there is no equivalent to the 3-year lock-in that applies when an adjusted fixed asset is acquired (Consumption Tax Act, Article 37, Paragraph 6).
- Filing the revocation notification reverts you to the standard scheme (actual deduction) starting the next taxable period. It's worth using the simplified_taxation_judge tool beforehand to check which scheme is actually more advantageous.
- If your base-period taxable sales exceed 50 million yen, you automatically lose eligibility for the simplified scheme without needing to file a revocation notification — that case is outside the scope of this tool.
- This tool assumes a 12-month taxable period. Corporations with a shorter first fiscal year may have a different actual deadline, so confirm with a tax accountant.
Use Cases
Planning the timing to switch back to the standard scheme
A business whose taxable purchases have grown enough to make the simplified scheme unfavorable can plan the exact date it becomes eligible to revert to the standard scheme.
Preparing for a meeting with a tax accountant
Knowing the approximate revocation window and deadline in advance helps you get more out of a consultation with a tax professional.
Combining with the simplified-vs-standard advantage judgment
After using simplified_taxation_judge to see which scheme is more advantageous, use this tool to work out the concrete schedule for actually switching.

Frequently Asked Questions
Side Note — Why Is Revoking the Simplified Scheme So Much Simpler?
Revoking the Taxable Person Election comes with a tricky exception on top of its 2-year commitment: a 3-year lock-in that kicks in after a large capital investment. That rule exists to stop a business from claiming a refund and immediately reverting to exempt status — a kind of cherry-picking the system is designed to prevent.
The simplified taxation scheme, by contrast, isn't a refund mechanism at all — it's simply a simplified way of calculating the deduction using a deemed purchase rate. A business on the simplified scheme generally can't receive a refund in the first place (even if the deemed deduction exceeds the actual amount, the excess isn't refunded), so there's little incentive to game the timing around a capital investment.
That structural difference is exactly why the simplified scheme's commitment period is defined simply as 2 years under Article 37, Paragraph 6 of the Consumption Tax Act, with no extension rule like the one attached to the Taxable Person Election. It's a neat example of how the purpose behind a notification shapes how complicated its rules end up being.
