Invoice Registration Application Deadline Calculator (Japan Qualified Invoice Issuer)
Work out, for free, the filing deadline for the application to become a Qualified Invoice Issuer (Japan invoice/インボイス). Just enter your desired registration date to see the 15-day deadline and whether the transitional measure applies.
What Is the Invoice Registration Application Deadline Calculator?
The Invoice Registration Application Deadline Calculator works out the filing deadline for the application to become a Qualified Invoice Issuer under Japan's invoice system. Just enter the date you want registration to take effect, and the tool automatically calculates the deadline, 15 days earlier.
A transitional measure running from October 1, 2023 through September 30, 2029 lets you name any date at least 15 days after your filing date as your "desired registration date." This tool automatically checks whether your entered date falls within that window, and if the filing deadline has already passed, it also shows the earliest date you could register if you filed today.
How to Use
- Enter the date you want registration to take effect Select the date you want to become a Qualified Invoice Issuer — for example, next January 1 for a sole proprietor, or the day after your fiscal year end for a corporation.
- Check your result See the filing deadline (15 days before) and whether the transitional measure applies. If that deadline has already passed, you'll also see the earliest date you could register if you filed today.
Tips for getting more out of it
- The filing deadline is the day that falls 15 days before the date you want registration to take effect. If you miss it, you cannot register from your requested date — but during the transitional measure, you can simply re-file with the earliest date you could register if you filed today (15 days from now) as your new target.
- A 6-year transitional measure runs from October 1, 2023 through September 30, 2029. During this window, you can name any date at least 15 days after your filing date as your "desired registration date." Without this measure, registration is generally only possible from the start of a taxable period.
- Once the transitional measure ends (September 30, 2029), registration will generally only be possible from the start of a taxable period — January 1 for sole proprietors, or the start of the fiscal year for corporations.
- Registering makes you a taxable person for consumption tax from your effective date onward, regardless of your taxable sales. Before registering, check taxable_person_judge for your current taxable/exempt status and invoice_two_percent_special_provision for whether the post-registration relief measure applies to you.
- It typically takes about a month to receive your registration notice after e-Tax filing, or about six weeks for paper filing. Build in extra lead time so you can notify business partners of your registration number on schedule.

Frequently Asked Questions
Side Note — Why the "15 Days Before" Rule Comes Paired With a Transitional Measure
When Japan's invoice system launched in October 2023, the basic rule was that registration could only take effect from the start of a taxable period — January 1 for a sole proprietor, or the start of the fiscal year for a corporation. This was because the registration's effect needed to align with the unit of time used to calculate consumption tax liability.
For small business owners who were still negotiating prices with trading partners or updating their systems right up until the launch, being locked into a fixed date was a real burden. So a 6-year transitional measure was introduced, running from October 1, 2023 through September 30, 2029: during this window, businesses could name any date at least 15 days after their filing date as their "desired registration date," letting them register whenever suited them.
This transitional measure pairs with the "15 days before" rule introduced by the 2023 tax reform (the same rule also applies to registration cancellation), letting businesses plan flexibly around "a date at least 15 days from today." Because the transitional measure ends on September 30, 2029, anyone planning a new registration after that date will need to schedule around the start of a taxable period instead.
