The 12,000 islanders who haven’t filed their tax returns yet have been reminded that they need to “act promptly” to do so.
Tax returns are due on 31 July.
55,013 tax returns have already been filed out of the approximately 67,000 expected by the Tax Department.
When filing their returns, islanders have to set up their OneGov accounts and set up digital ID, which authorities have warned can take some time.
Comptroller of Revenue, Richard Summersgill, said: “Islanders must allow time to activate a onegov account and complete digital ID setup.
“Verification delays can occur, so we urge taxpayers to act promptly and use the guidance available to avoid late filing penalties.”
Authorities also warned that those who miss the filing deadline will have a £300 fine added to their assessment and receive a ‘Default Assessment’, calculated based on the information the Tax Department already holds.
Those who are more than three months late filing get an additional £50 penalty for each month, up to a maximum of £750.
