Dealing with tax matters after someone has passed away can be difficult, particularly when you are also handling probate, assets, debts and communication with beneficiaries. One of the questions executors commonly face is when the estate needs to lodge a tax return.
The answer is not always as simple as choosing one fixed date. The tax treatment of a deceased estate depends on what happened before and after the person’s death, whether the estate earned income, and which type of return needs to be lodged.
Understanding the deceased estate tax return due date can help an executor avoid unnecessary delays and keep the administration of the estate on track.
This guide explains how the deadlines work, what type of return may be required, who is responsible for lodging it and what to do if the estate needs more time.
When a person dies, their tax affairs do not simply end on the date of death. There can be income earned by the person before their death and income earned by the estate afterwards.
These are generally dealt with separately.
The deceased person’s final individual tax return, commonly called a date-of-death return, covers the relevant income earned from the beginning of the financial year until the date they died. The estate’s income after death is dealt with separately, and where a return is required, the estate is generally treated as a trust for tax purposes.
There is no single universal date that applies to every deceased estate.
A deceased estate that is required to lodge a trust tax return generally follows the ATO’s trust return lodgment framework. For ordinary trusts that are not subject to an earlier due date, the standard lodgment date is generally 15 May, although eligible taxpayers using a registered tax agent may receive the relevant agent-program concessions.
Therefore, the deceased estate tax return due date depends on the estate’s circumstances and the lodgment arrangements applying to it.
Executors should not assume that every estate has the same deadline simply because the financial year ends on 30 June.
30 June is important because it marks the end of the Australian financial year. It is not automatically the lodgment deadline for the estate’s tax return.
An estate may have a tax obligation for the income it receives during the financial year and then have a later date by which the relevant return must be lodged.
This is why executors should distinguish between the end of the income year and the tax return lodgment deadline.
Yes.
The deceased person’s final tax return is separate from the deceased estate’s trust tax return.
The date-of-death return covers the deceased person’s tax affairs up to the date of death. The estate return deals with income and other relevant amounts received by the estate after death.
For example, if Sarah died on 10 February 2026, her executor may need to prepare a final individual return covering the period from 1 July 2025 to 10 February 2026.
If Sarah’s estate then receives bank interest or rental income between 11 February and 30 June 2026, that post-death income is dealt with as income of the estate.
This distinction is important when reviewing the deceased estate tax obligations.
Not every deceased estate necessarily has to lodge a trust tax return every year.
The requirement depends on factors including the estate’s income, beneficiaries and the income year involved. The ATO has specific rules applying during the first three income years of a deceased estate and different considerations for later years.
An estate may also choose to lodge a return in certain circumstances where one is not strictly required, such as where it needs to claim franking credits.
This means an executor should consider the estate’s actual circumstances rather than assuming that a return is automatically required or unnecessary.
During the first three income years, specific rules apply when determining whether the deceased estate needs to lodge a trust tax return.
The executor should consider the estate’s net income, beneficiary entitlements and residency circumstances before deciding whether a return is required.
From the fourth income year onwards, the rules change. Where the estate earns income, including relevant capital gains, a trust tax return may be required.
An estate that takes several years to administer therefore should not be treated as though its tax obligations ended after the first return.
A deceased estate can receive different types of income while it is being administered.
Depending on the circumstances, this can include:
Income received by the estate after death needs to be considered when determining its tax obligations.
If the estate owns an investment property that continues to generate rent after the person’s death, that income needs to be considered as part of the estate’s tax affairs.
The executor should keep records of rental receipts and relevant expenses throughout the administration period.
Bank interest, dividends and other investment income can also be received by an estate.
Keeping investment statements and transaction records organised makes it easier to identify all amounts that need to be considered when preparing the return.
Property and other assets can create additional tax considerations when they are sold.
The treatment can depend on factors such as how the asset was acquired, whether it was the deceased person’s main residence, when it was transferred and when it was eventually sold.
Executors dealing with property should therefore understand the rules surrounding capital gains tax on inherited property before finalising the estate.
In some circumstances, yes.
An executor does not necessarily have to wait until the end of the financial year to finalise an estate’s tax affairs. Where the administration has been completed and the estate is not expected to receive further income, the final trust return may be able to be lodged.
However, lodging too early can create problems if the estate is still receiving income.
For example, an estate may have an investment property that continues producing rent, or a dividend may be received after the executor believes the tax affairs are complete.
The executor therefore needs to consider whether the estate has genuinely reached the point where no further income is expected.
Missing a tax lodgment deadline can create unnecessary complications for an executor.
The ATO may contact the legal personal representative about an outstanding return. Depending on the circumstances, penalties or other consequences may apply.
More importantly, delaying the return can hold up the broader process of finalising the estate. Beneficiaries may be waiting for distributions, property transactions may still need to be completed, and the executor may need evidence that the estate’s tax affairs have been properly dealt with.
If the executor realises that the deceased estate tax return due date cannot be met, it is better to address the issue promptly rather than simply allowing the deadline to pass.
A tax professional can assess the circumstances and determine whether an extension or other arrangement should be discussed with the ATO.
Good record-keeping makes the tax process much easier.
The executor should keep records relating to the deceased person’s financial affairs and the estate’s transactions after death.
Depending on the estate, useful documents can include:
Having these records available early can help an accountant determine what needs to be reported and whether additional tax returns are required.
A separate deceased estate tax return checklist can also be useful when gathering information before the return is prepared.
The tax obligations of an estate can continue for more than one financial year.
A deceased estate may need to lodge a trust tax return for multiple years if it continues to earn income or otherwise meets the applicable requirements.
This means there is no rule saying that one tax return automatically closes every tax obligation connected with an estate.
An estate that takes several years to administer may therefore have several reporting periods.
The estate should generally only be treated as finalised once its administration is complete and no further income or tax obligations are expected.
The executor should ensure that outstanding tax matters have been addressed before considering the estate fully closed.
Estate administration can become complicated when there are multiple beneficiaries, investment properties, businesses, shares, overseas assets or significant capital gains.
Professional assistance can be particularly useful when:
Working with a Deceased Estate Accountant can help the executor understand which returns are required, organise supporting records and deal with tax matters while the estate is being administered.
For Perth-based executors, a tax accountant perth can also help with the practical tax requirements involved in administering an estate.
Understanding the deceased estate tax return due date is an important part of administering an estate, but the deadline should not be considered in isolation.
Executors also need to determine which return is required, identify income earned after death, maintain accurate records and consider whether the estate will continue into another financial year.
Where an estate involves property, investments, business interests or complicated beneficiary arrangements, professional guidance can be especially valuable.
If you are an executor dealing with a deceased estate in Perth and are unsure about the estate’s tax return requirements or lodgment timing, speaking with a qualified professional can help you understand the next steps before a deadline is missed.
