Japan is expanding the scope of notices delivered electronically via e-Tax, enabling unified consent and streamlining tax compliance obligations—what all taxpayers need to know now.

## What is Changing: Electronic Delivery of Tax Notices
Japan’s National Tax Agency (NTA) has announced new procedures under which various tax notifications and **処分通知等**, including notices of assessments, refunds, and other official communications, will increasingly be delivered **electronically via the e-Tax portal**.([e-tax.nta.go.jp](https://www.e-tax.nta.go.jp/kakunin/index.htm?utm_source=openai))
### Key Features of the New System
- Starting **September 24, 2026**, taxpayers who wish to receive notifications electronically must provide **one-time unified consent** (“一括同意”) through e-Tax, replacing the previous “per-notice consent” model.([e-tax.nta.go.jp](https://www.e-tax.nta.go.jp/kakunin/index.htm?utm_source=openai))
- Notifications such as assessment notices, notices of added taxes (加算税) in enforcement proceedings, and notices related to credit for housing loan deductions may all be included. Consent is required only once via e-Tax.([e-tax.nta.go.jp](https://www.e-tax.nta.go.jp/kakunin/index.htm?utm_source=openai))
- Some notices will continue being delivered electronically without needing new consent if prior consent was already given before September 23, 2026.([e-tax.nta.go.jp](https://www.e-tax.nta.go.jp/kakunin/index.htm?utm_source=openai))
## Who Is Affected & Why It Matters
- **All taxpayers**—individuals, entities, and non-residents with tax obligations in Japan—should review their notification preferences in e-Tax and decide whether to opt in for unified consent.
- **Non-residents or those departing Japan during the year** must ensure they maintain access to e-Tax, or appoint tax agents, to receive notices and avoid missing deadlines. Related with exit tax and final returns.([nta.go.jp](https://www.nta.go.jp/english/taxes/individual/pdf/incometax_2025/21.pdf?utm_source=openai))
## Action Steps for Taxpayers
1. Log in to **e-Tax** before **September 24, 2026** to provide “一括同意” for electronic delivery.
2. Check which notifications you currently receive in paper form—these may go digital after the change.
3. For foreign nationals, digital nomads, or expats, ensure a valid Japanese address or appointed tax agent to receive communications.
4. Keep electronic copies of all notices—once in effect, some paper notices may stop or become optional.
## Compliance Risks to Watch
- Missing a notice (e.g. assessments, refund decisions) because you didn’t consent may cause missed deadlines or penalties.
- If your mailing address is out of date, even electronic notices may be inaccessible.
- Businesses with multiple entities should ensure all responsible persons understand where notices are sent and who monitors the e-Tax inbox.
## Practical Example
Suppose you have been filing tax returns and routinely receiving assessment notices via paper addressed to your Tokyo office. After September 24, these will automatically go into your e-Tax secure mailbox if you give unified consent. Failing to do so might mean you miss a digital-only notice relating to a **blue return special deduction audit**, incurring penalties.
This digital transformation in Japan’s tax administration tightens turnaround, reduces costs, and emphasizes staying connected\,—through e-Tax consent or via authorized agents. It’s a small procedural step but essential for timely compliance.
