3. My parents are joint owners of the property. If they are unable to write, how can they sign the Tax Return (B.I.R.57)?

If the owner is unable to write, the affixing of a name-chop, thumbprint or mark (such as “x”) as the owner's signature can be accepted, if properly witnessed by a person aged 18 or above. The witness should sign and date the form, and state his/her full name and Identity Card number beside his / her signature.


An alternative to the above is that if you have a written authorization from the owners, you can complete the Return on their behalf. You should attach a copy of the relevant Power of Attorney or Letter of Authorization to the tax return if this is the first time you act as the agent or representative for them.
