Some WHOIS utilities state my domain expires next year, but your WHOIS servers states this year! Which one is correct?
The expiry date located in the Tucows WHOIS database is always correct. To provide you with a 40 day grace period when the domain expires, we must submit a temporary renewal to the Registry.
This is what you are seeing when you perform a WHOIS lookup at a central Registry (such as Internic for .COM/.NET domains) on your expired domain name.
Please note this DISCLAIMER presented in the Internic WHOIS:
NOTICE: The expiration date displayed in this record is the date the Registrar sponsorship of the domain name registration in the registry is currently set to expire. This date does not necessarily reflect the expiration date of the domain name Registrant Agreement with the sponsoring Registrar. Users may consult the sponsoring Registrar’s WHOIS database to view the Registrar’s reported date of expiration for this registration.
