Which Revenue form is used when one wishes to reduce their tax liability by claiming the beneficiary threshold of e335000 following the sale of a house they inherited? Also, what supporting documents would the beneficiary require to present to Revenue when completing the correct form. This house was not purchased by me and sold at a profit so there was no chargeable gain, the house was my old family home which was assigned to me by a parent. Some people tell me i should complete CG1, others say IT38, i would like to know which is the correct form to use.
