Generally, the same filing requirements apply to a deceased taxpayer as would otherwise be used if the taxpayer were still living, based on income level, age, and filing status. CAUTION: A fiduciary return may also be required.
Refunds- If a decedent's return claims a refund, Form 1310, Statement of Person Claiming Refund Due a Deceased Taxpayer, should be filed. However, Form 1310 is not needed if:
Income to Include - The decedent's income on the final return generally includes income derived up to the date of death.
Exemptions and Deductions - The general rules for exemptions and deductions apply to the final return.
Other Tax Attributes – What becomes of other tax carryovers attributable to the taxpayer upon his or her death? To the extent that the following carryovers are attributable to the taxpayer (in the case of a married taxpayer all or half of the carryover on a joint return may be attributable to the surviving spouse), the balance of the following carryovers are lost.
Special rules apply to the carryovers of foreign tax credit, domestic production deduction and unrecovered basis in the decedent’s pension. In addition, any unsatisfied term of the moving deduction qualification period is waived. The treatment of a decedent’s unused capital loss carryover may be different for decedents dying in 2010, depending on the taxation method chosen by the executor, as explained in the article “Federal Estate Tax Retroactively Reinstated.”
Return Signature, Etc - The word "DECEASED," the decedent's name and the date of death should be written at the top of page one of Form 1040. If there is a personal representative, that person must sign the return. If the return is joint, the surviving spouse must also sign. If there isn't a representative and the return is joint, the surviving spouse signs the return and notes in the signature area: "Filing as surviving spouse". If the decedent had no representative or wasn't married, the person in charge of the decedent's property should sign as "personal representative."
Due Date - Due date for the decedent's return is the same as for any other taxpayer, regardless of the date of death during the year.
