This domain is flagged as an active phishing site targeting UK taxpayers by impersonating official HMRC tax refund guidance. Visitors to polymarket-tax.co.uk are presented with a fraudulent page titled 'Polymarket UK Tax — HMRC Guide 2026,' designed to harvest personal and financial information under the guise of legitimate tax services. The site poses a direct risk of identity theft, financial fraud, and unauthorized access to sensitive government-related accounts.

Analysis indicates the domain was registered on April 17, 2026, through Namecheap, Inc., and currently resolves to the IP address 188.114.97.3. Despite its recent creation, the site has not yet been flagged by security vendors, with 0 out of 95 detections reported on VirusTotal. The SSL certificate is issued by Google Trust Services, which may lend a false sense of legitimacy to unsuspecting users. Infrastructure review confirms the site remains operational and unblocked by most security filters.

Individuals who have visited polymarket-tax.co.uk should immediately cease all interaction with the site. If any personal, financial, or login details were entered, affected parties should report the incident to Action Fraud and HMRC’s official phishing reporting channels. Monitor bank accounts and credit reports for unauthorized activity, and consider placing a fraud alert with credit reference agencies. Update passwords for any accounts that may have been compromised, and enable multi-factor authentication where possible to mitigate further risk.
