Is .tax safe? The state of .tax domain security
.tax is about average for the internet. Across 16,727 graded .tax domains, 80.7% score an F — roughly in line with the 78.3% global average. 2% earn a B or better. Most .tax domains can still be impersonated in email, but the ending shifts the odds, not your own domain's grade. As of 2026-08-16.
Of 15,654 graded .tax domains, 76.9% earn an F — above the 73.8% internet-wide average. DMARC enforcement here stands at 14.8% — above the 11.8% census-wide rate.
How do .tax domains score?
Aggregate grade distribution across all graded .tax domains — we never publish an individual business's grade. As of 2026-08-16.
| Grade | Domains | Share |
|---|---|---|
| A+ | 4 | 0% |
| A | 33 | 0.2% |
| B | 292 | 1.7% |
| C | 937 | 5.6% |
| D | 1,962 | 11.7% |
| F | 13,499 | 80.7% |
Does .tax make a domain secure?
No — and that's the most important thing to know. A domain's grade is decided by how it is configured (SPF, DMARC, HTTPS, DNS), not by its ending. Choosing .tax doesn't protect you, and a high-F-share ending doesn't doom you: a correctly configured .tax domain earns an A while the crowd around it sits at F.

Frequently asked questions
Is .tax safe?
On average, .tax is about average for the internet: 80.7% of its 16,727 graded domains score an F as of 2026-08-16, against a 78.3% global average. Most domains on every ending are exposed — the ending shifts the odds, not your own domain's grade.
How secure are .tax domains?
19.3% of .tax domains score above an F and 2% earn a B or better. The rest fail the basic externally observable protections, most importantly enforced SPF and DMARC, so they can be impersonated in email.
Does choosing .tax make my domain secure?
No. A domain's grade comes from how it is configured — SPF, DMARC, HTTPS, DNS — not from its ending. A well-configured domain earns an A on any ending; an unconfigured one sits at F on .tax too.
What does "grade F" mean for a .tax domain?
It fails the basic protections we can observe from outside — above all, it has no enforced SPF and DMARC, so its email can be forged and its customers targeted with convincing fakes.
