ATO Deceased Estate: Tax Returns, TFNs, and Deadlines Executors Must Know

The bank accounts are frozen, the funeral is paid for, and now the ATO wants its share. Most executors discover — usually too late — that the Australian Taxation Office treats the deceased person and their estate as two completely separate tax entities. That means two different tax file numbers, two different types of returns, and a 3-year tax concession period that nobody warns you about until the penalties arrive.

Here's what you actually need to do, in order.

The Date-of-Death Tax Return

Your first obligation is lodging a final individual tax return for the person who died. This return covers income earned from 1 July of the current financial year up to the exact date of death — not a day more.

You'll need to gather:

• Payment summaries from employers or superannuation funds
• Bank interest statements (request these directly — the deceased won't receive an annual statement)
• Dividend statements from share registries
• Rental income records up to the date of death
• Any capital gains triggered by asset disposals before death

Lodge this return under the deceased's existing TFN and mark it as "final" so the ATO can close the individual record.

One trap: if the deceased was receiving a government pension and it wasn't cancelled promptly after death, those overpayments can become a debt the estate owes. Notify Services Australia promptly.

The Estate Trust TFN — A Separate Entity

Once the date-of-death return is lodged, the estate itself becomes a trust for tax purposes. You need to apply for a brand new Trust Tax File Number through the ATO. This is not optional — any income the estate earns after the date of death (rent from a property still in the estate, dividends from unsold shares, bank interest on the estate account) must be reported under this new TFN.

Apply through the ATO's deceased-estate trust process. Keep the Grant of Probate or Letters of Administration available as supporting documentation.

The Estate Trust Tax Return

For each financial year in which the estate earns reportable income, lodge a Trust Tax Return reporting income earned by estate assets. This includes:

• Interest on the estate bank account
• Rental income from property held in the estate
• Dividends from shares not yet transferred to beneficiaries
• Capital gains from selling estate assets, including property or shares

The estate may receive concessional tax treatment for the first 3 years from the date of death. After that, undistributed income may be taxed at penalised rates.

The 3-Year Cliff

This is the tax point that catches executors who let estates drag on. For the first 3 years after death, the deceased estate trust receives concessional tax treatment. After 3 years, the ATO's concessions end and undistributed income may be taxed at heavily penalised rates.

If you're still holding assets in the estate after 3 years because of a contested will or slow property sale, the tax hit is brutal. This is one of the strongest arguments for distributing assets as efficiently as possible once the 6-month family provision claim period expires.

Capital Gains Tax on Inherited Assets

The CGT treatment of inherited assets depends on the asset, when the deceased acquired it, its use, and what happens after death. Inherited assets and later sales can have different tax consequences. The main-residence rules can also apply differently after death and depend on conditions, so obtain tax advice before relying on an exemption or timing a sale.

Superannuation Death Benefits

Superannuation is generally held outside the estate. Whether a death benefit is paid to the estate or directly to a beneficiary depends on the nomination and the fund trustee's decision. The tax treatment depends on who receives the payout:

• Tax dependants (spouse, child under 18, financial dependant): Death benefits are generally tax-free.
• Non-tax dependants (adult children, siblings, friends): Death benefits may be subject to significant tax; the exact treatment depends on the components and the recipient.

This distinction catches families off guard. A non-tax dependant can face a significant tax liability on a superannuation death benefit.

What to Do First

1. Notify the ATO through its deceased-estate process
2. Lodge the date-of-death individual return under the existing TFN
3. Apply for a Trust TFN for the estate
4. Open a dedicated estate bank account and direct all post-death income there
5. Lodge required Trust Tax Returns for each financial year with reportable estate income until the estate is fully distributed
6. Aim to finalise the estate before the 3-year concessional period ends if possible

If the estate involves superannuation paid to non-dependants, complex CGT calculations, or assets held in a company or trust structure, engage a tax professional. Tax errors can lead to penalties.
