Your personal income tax return form for the year ending 5 April 2012 must be completed and returned by 6 October 2012.
Failure to submit the return form by the due date will result in an automatic penalty of £100 which will be due and payable immediately.
If you have not received a return form and are not sure whether you need to complete one, please contact us on 685400.
Please remember that if you have a tax agent your return will have been sent to them unless you have instructed us otherwise, and you should contact your agent initially.
Every year hundreds of people move address and some fail to inform the Income Tax Division of their move. This could result in delays in processing your assessment and getting any refund to you. The absence of an address will slow down these processes, but it will not prevent penalties being triggered if, for example, you do not receive a return form before the date on which it should be submitted
You can inform the Income Tax Division of address changes either in writing or by using the ‘Contact Us’ facility here
You can also update your own address record by using the Online Tax Services once you have registered and enrolled for Individual Tax Services
Do you have a mortgage subject to a flexible rate of interest, e.g. base rate tracker mortgages? If so, have you asked for your code to be amended to reflect the reduced amount of interest you are paying?
Lower interest rates will result in lower claims for mortgage interest relief and if your code has not been changed you may receive more relief through your code than you should. This may result in an underpayment when your assessment is calculated.
We will look at your code when preparing your latest assessment, but we then have to rely on you to inform us when changes affecting your code take place.
- Paying off a loan that you have been claiming tax relief for
- Ceasing to make payments under a maintenance agreement or deed of covenant
- Being given the use of an asset owned by your employer (e.g. a car, or accommodation)
- Taking out a new loan that may qualify for tax relief
- Commencing to make payments under a maintenance agreement or deed of covenant
If changes occur you should tell us immediately to reduce the risk of under or over payments of income tax. You can inform us of changes by using the ‘Contact Us’ facility here , or by contacting the Division on 685400.
Please note, you are required to submit a tax return annually whether we issue one to you or not. If you have not already done so, you should register for Isle of Man income tax as soon as possible.

Penalties may be due if you register late and have not submitted a completed income tax return by the due date.
Income tax returns for trusts and settlements must also be completed and submitted by 6 October 2012 in order to avoid a penalty notice.
If you have not received an income tax return and you have not been advised in writing that the trust or settlement is not required to submit annual income tax returns, please contact the Division on 685400.
If you are leaving the Island permanently, you must file a return for the period beginning 6 April 2012 (if you left after that date) up to the date of departure.
Failure to submit the return within 6 months of the date of your departure will trigger an automatic £100 penalty.
You should contact the Division as details of your departure are confirmed, to obtain the return(s) needed to bring your income tax affairs to a close here on the Isle of Man.
