Hi Amberley,
Yes details of the disposal need to be included on your tax return for the year. Details are included in Section L of the Form 11.
Are you and your partner married? If so a joint tax return will be filed including details for both of you (assuming no election has been made to be treated separately for tax purposes). If not your partner will need to file his own tax return (probably a form 12 for a PAYE taxpayer).
You state in your e-mail that the property was first rented out in November 2007. If this is the case, details of rental income for November and December 2007 should have been included on 2007 tax returns. Was this done?
Just to note, when caclulating the net rental income on the property you should only take a deduction for the mortgage interest i.e. no deduction should be taken for the capital element of the loan repayments. This deduction for mortgage interest is only available if the tenency has been registered with the Private Residential Tenancy Board. Has this been done?
If the property was let funrnished you should also be able to claim a wear and tear allowance when calculating the net rental income.
There is a lot of information on the tax treatment of rental income on the Revenue website so maybe have a look there first before deciding whether you need an accountant/tax consultant to assist you with the tax return.
