National Tax Agency (NTA): Official SMS Senders & Numbers - Is That SMS Genuine?

Officially states it does not send SMS

Do they send SMS? (Official statements)

The NTA officially states it never sends SMS containing URLs, and never sends SMS/email/LINE messages demanding tax payment or announcing asset seizure.

Officially published senders

No official sender (number or display name) list is published.

The NTA states it sends no URL-bearing SMS and no payment-demand SMS.

Conversely, a message showing a listed name or number is NOT necessarily genuine: SMS sender displays can be spoofed. The safest approach is to avoid links in the message and check directly via the official app or a bookmarked official website.

Key points from official statements

The NTA never sends URL-bearing SMS; "unpaid tax" or "tax refund" SMS with links are scams.
The NTA never demands payment or announces seizures via SMS, email or LINE.
e-Tax emails follow published patterns only, contain no attachments, and in principle include no URLs.
The NTA never asks taxpayers to operate ATMs for refunds or payments.

How to use this list correctly (disclaimer)

A sender not on this list is NOT necessarily a scam. Companies may add or change senders without notice, and legitimate SMS may arrive from numbers or names that are not officially published.
