During deceased estate administration, income the trustee retains is generally taxed at individual marginal rates under section 99 for a reasonable period — typically up to three years from death. Beyond that, the ATO increasingly applies the 47% top penalty rate under section 99A, unless executors make beneficiaries presently entitled to the income each year under section 97.
For Australian executors and family advisers managing deceased estates, the taxation of trust income during the estate administration period is governed by sections 99 and 99A of the Income Tax Assessment Act 1936. Where no beneficiary is presently entitled to estate income for a year, the income is taxed in the hands of the trustee under either section 99 at progressive marginal rates similar to those for an individual taxpayer, or section 99A at the top marginal rate of 45% plus 2% Medicare levy (effectively 47%). Section 99A is the statutory default; section 99 applies only where the Commissioner exercises the discretion in s.99A(2) to do so. For deceased estates, the Commissioner's long-standing administrative practice is to apply s.99 marginal rates during a reasonable period of administration — typically the first three years from the date of death — with s.99A penalty rates increasingly likely beyond that period unless specific facts justify continued s.99 treatment. The framework reflects a policy balance: estates legitimately need time for asset valuation, debt resolution, beneficiary identification, and dispute resolution, but indefinite retention of income in the estate is discouraged through penalty taxation. For most estates that complete administration and distribute within 18–24 months, the rule is not a binding constraint — income flows to beneficiaries via present entitlement under section 97 and the s.99A penalty rate never engages. For complex, contested, or international estates that take longer than three years, the framework becomes the central planning issue, with executors needing to actively structure present entitlement of income to beneficiaries on a year-by-year basis to avoid the penalty rate.
The basic framework of sections 97, 99 and 99A is fundamental to estate income taxation. Section 97 includes in a beneficiary's assessable income the share of the trust's net income to which the beneficiary is presently entitled — the beneficiary pays personal tax on that share at their personal marginal rate, with full credit for franking and other attributes. Where no beneficiary is presently entitled, section 99 provides that the trustee is assessed on that income, with the s.99 rates being progressive marginal rates similar to those for an individual taxpayer (including the $18,200 tax-free threshold and the FY25-26 stage-3 brackets). Section 99A provides the default rule: trustee income to which no beneficiary is presently entitled is taxed at the top marginal rate of 45% plus 2% Medicare levy = 47%, unless the Commissioner exercises the s.99A(2) discretion to apply s.99 instead. The contrast between these rates is stark — substantial estate income could face an effective rate of $5,000 (s.99 marginal at a notional $50,000 income year) versus $23,500 (s.99A top rate) on the same income, with the gap widening at larger income levels. For estates with material annual income — investment portfolios, business interests, rental properties, distributions from family trusts — the rate difference can amount to tens or hundreds of thousands of dollars over an extended administration.
The three-year reasonable-administration period is administrative practice rather than a black-letter statutory deadline. The ATO's published guidance confirms that during a reasonable period of administration — generally up to three years from the date of death — the Commissioner will typically exercise the s.99A(2) discretion to apply s.99 marginal rates to estate income retained in the estate. The trustee can therefore choose to retain income in the estate during this period without triggering penalty taxation. After the three-year mark, the s.99A(2) discretion is harder to obtain without specific justification (genuine ongoing administration complexity, contested probate, foreign-asset issues, beneficiary identification problems and similar). Without that justification, retained income falls to s.99A top-marginal-rate treatment. The shift is not strictly automatic — it depends on the Commissioner's exercise of discretion — but in practice, executors who don't actively plan around the three-year deadline find themselves either paying penalty rates or having to justify the extended administration to the ATO.
The policy rationale for the framework reflects a balance of considerations. Estates legitimately need time — typical Australian estate administration involves obtaining a grant of probate (one to three months for uncontested wills), identifying and valuing all assets (often several months to a year for complex estates), paying debts and tax liabilities, identifying all beneficiaries (sometimes a research project), realising assets for distribution if the will so directs, resolving any will disputes or family provision claims, and finally distributing the residual estate. Three years is generous for most estates and tight for complex ones. The s.99 concession recognises that during this period, retention of income in the estate is part of normal administration. The s.99A default rate beyond three years reflects policy concern about indefinite trust accumulation — without a penalty, executors and beneficiaries might prefer to keep income retained in the estate for tax deferral rather than distributing currently. The rule channels behaviour toward prompt distribution.
The estate income components during administration can be substantial. Investment income from estate assets — interest from term deposits, dividends from share portfolios, distributions from managed funds — accrues during administration. Capital gains realised on disposal of estate assets (where the executor sells assets for cash distribution rather than transferring assets in specie) flow into estate income. Continuing business income from any business operated through the estate (for example where the deceased was running a small business that needs ongoing management until sale or transfer). Rental income from estate-owned properties. Distributions from family trusts where the deceased was a beneficiary or controller, with the estate continuing to receive distributions until the trust is restructured. Foreign income from offshore assets, which may have its own complexity. For estates with substantial financial wealth, annual income can easily run into six or seven figures — making the s.99 versus s.99A distinction materially significant.
The scenarios producing extended administration are reasonably common in practice. Will disputes are the leading cause — family provision claims under state succession legislation, will validity challenges, executor removal applications, and probate disputes can extend administration by one to five years or more depending on complexity. Complex assets including foreign property requiring overseas probate, business interests requiring valuation and sale or transfer arrangements, illiquid investments (private equity, art, collectibles), and intellectual property requiring specialist valuation. Beneficiary identification issues including unidentified beneficiaries (the deceased had not maintained contact with all entitled persons), missing heirs requiring genealogical research, and beneficiaries with capacity issues requiring guardianship orders. Tax disputes with the ATO including audit, foreign income disputes, unresolved deceased's tax liabilities. Trust structures including testamentary trusts with deferred vesting that effectively extend the administration timeline. For any of these reasons, an estate that "should" complete in 12–18 months can extend to four to six years.
The "presently entitled" concept is the central planning lever for executors of extended estates. A beneficiary is "presently entitled" to estate income (or specific share of it) if they have a vested and indefeasible interest in the income, with the right to demand payment from the trustee. Where the will directs that specific beneficiaries are entitled to specific income or proportions, the present entitlement is established by the will itself. Where the will gives the trustee discretion, the trustee can resolve before 30 June each year that specified beneficiaries are presently entitled to specified income for the year — making the beneficiaries currently taxable on the income under s.97 at their personal marginal rates while the underlying funds remain in the estate. The trustee's resolution doesn't require physical distribution of cash — it establishes the legal entitlement, with payment to follow as estate funds permit. For complex estates beyond the three-year mark, year-by-year resolutions of present entitlement effectively shift the tax burden from the estate (at penalty rate) to the beneficiaries (at their marginal rates), preserving the income for eventual distribution while avoiding s.99A.
The interim distribution strategy for extended estates has a specific shape. Identify income versus capital flows in the estate accounting — separate the categories so that current-year income is clearly identified for entitlement purposes. Interim distributions of income to beneficiaries on a current-year basis, even where capital remains in the estate (because of unresolved disputes, unrealised assets, or other administration issues). Resolutions of present entitlement before each 30 June, where the will or trust law permits trustee discretion — establishing tax entitlement for the year. Disclaimer or refusal by beneficiaries in some circumstances — a beneficiary may disclaim entitlement (transferring the tax burden to other beneficiaries or back to the estate at penalty rate), but disclaimers must be done correctly to avoid trust law issues and may have unintended consequences. CGT realisation timing — capital gains crystallise to the estate when assets are sold; planning the realisation timing matters for managing the s.99 versus s.99A boundary.
The capital gains complexity during administration adds another layer. Capital gains realised by the estate on disposal of estate assets are assessable to the estate (s.99 or s.99A treatment depending on the period and the Commissioner's discretion). Where beneficiaries are presently entitled to capital, gains can flow through to the beneficiaries — but capital entitlement is harder to establish than income entitlement, often requiring specific will provisions or trustee resolutions. The CGT 50% discount is available if the asset has been held for more than 12 months — combining the deceased's holding period and the estate's holding period under ITAA 1997 s.115-30. Main residence exemption rules for inherited dwellings have their own framework (see the related article on articles/2026-05-04-cgt-2-year-inherited-dwelling-rule). For estates with substantial unrealised gains held into the post-three-year period, the timing of realisation matters — selling within Year 1–3 captures s.99 treatment if the gain ends up in the estate; selling in Year 4+ exposes the gain to s.99A treatment unless beneficiaries are made presently entitled to capital or the Commissioner extends the discretion.
The practical advice work for practitioners advising executors on extended estate administration has a specific shape. Identify the three-year deadline at outset — flag this as a key milestone in the estate administration plan. Plan distribution timeline to fall within three years where feasible — most estates can complete in this timeframe with active executor management. For unavoidable extensions, structure present entitlement of income to beneficiaries on a current-year basis under s.97. Coordinate with testamentary trust structures — when does estate close and trust begin? What are the trust's tax provisions? Manage capital gains realisation considering the s.99/s.99A timing — where possible, realise within Year 1–3, or structure capital entitlement for Year 4+. Document executor decisions clearly — present entitlement resolutions, distribution decisions, and tax positions all need contemporaneous documentation. Communicate with beneficiaries about the tax framework and cash flow implications — beneficiaries who become presently entitled to estate income owe tax even if they haven't received cash distribution yet.
What do worked planning examples show?
These two cases show how the 3-year rule plays out for typical estate scenarios. Illustrative only — not personal advice — using FY25-26 figures and post-1-July-2024 stage-3 marginal tax rates.
Case 1 — Estate of Robert, $4m total value. Deceased July 2023; administration delayed by family provision claim from estranged son, settled June 2026. Estate income during administration: $80,000 a year (dividends, interest, rental). On these facts, the administration period is approximately 35 months — within the three-year reasonable-administration window for the Commissioner's s.99A(2) discretion. Estate income for the three years is approximately $240,000 total. With s.99 treatment throughout, tax on the estate at the FY25-26 stage-3 marginal rates would be in the order of $50,000–$60,000 total. After settlement and distribution in 2026, no further estate income to manage. Outcome: clean administration within window, no s.99A exposure. The trap to avoid is allowing the administration to extend a few months past the three-year mark for "wrap-up" reasons — Year 4 income would likely face s.99A penalty rate unless specific justification is provided to the ATO.
Case 2 — Estate of Margaret, $7m total value. Deceased January 2022; administration delayed by foreign asset valuation issues and beneficiary capacity proceedings. Now mid-2026, still in administration. Estate income $150,000 a year. On these facts, the three-year reasonable-administration period ended January 2025. Without active management, Year 4 (2025) and Year 5 (2026) estate income faces s.99A penalty rate — approximately $70,000 of additional tax annually compared with marginal-rate treatment. Strategy: executor resolves before 30 June 2025 and 30 June 2026 that specified beneficiaries are presently entitled to current-year income under s.97. Tax flows through to beneficiaries at their marginal rates (for example, children with their own income placing the marginal slice in the 30% bracket would pay around $45,000 on $150,000 of additional income — well below the $70,000+ penalty rate the estate would pay at s.99A). Cash distribution follows when estate liquidity permits. The trap to avoid is failing to make the present entitlement resolutions — the cost of this failure is the s.99A penalty rate applied over multiple years.
For Australian executors and family advisers managing deceased estates, the section 99/99A framework with its three-year reasonable-administration boundary is one of the central tax planning considerations for extended administrations. Within the three-year window, retained estate income enjoys s.99 marginal rate treatment under the Commissioner's s.99A(2) discretion. Beyond three years, retained income is increasingly likely to be taxed at the 47% top marginal rate under s.99A unless beneficiaries are made presently entitled to the income on a current-year basis under s.97. The advice work is to identify the deadline early, plan administration timing to fall within the window where feasible, and where extension is unavoidable, structure present entitlement resolutions to flow income through to beneficiaries at their personal marginal rates. For complex or contested estates, getting this right can save substantial tax — the difference between marginal rate flow-through and penalty rate retention can run into hundreds of thousands of dollars over an extended administration. The cost of getting it wrong is borne by the residuary beneficiaries via reduced eventual distribution.

Key takeaways
- The ATO generally accepts marginal-rate section 99 tax treatment for estate income during a reasonable administration period, typically up to three years from death.
- Beyond three years, retained estate income risks the 47% top marginal rate under section 99A unless specific justification applies.
- Making beneficiaries presently entitled to income each year under section 97 shifts the tax to their personal marginal rates instead.
- Will disputes, foreign assets, and beneficiary identification issues are common causes of administration extending past three years.
- Present entitlement resolutions must generally be made before 30 June each year and don't require immediate cash payment.
Frequently asked questions
What happens to estate income if administration takes longer than three years?
Income retained in the estate beyond the ATO's accepted reasonable administration period (generally three years from death) is increasingly likely to be taxed at the top marginal rate of 47% under section 99A, rather than the individual-style marginal rates under section 99. Specific circumstances, like an ongoing contested probate, can sometimes justify continued section 99 treatment past three years.
How can an executor avoid the section 99A penalty rate on estate income?
The main lever is making beneficiaries presently entitled to the income for each tax year, generally by trustee resolution before 30 June. This shifts the tax liability to the beneficiaries at their own marginal rates under section 97, even if the cash isn't distributed until later.
Does present entitlement mean beneficiaries have to receive the cash straight away?
No. A trustee resolution establishing present entitlement creates the legal right to the income and the tax liability for the beneficiary, but actual payment can follow later once estate funds and liquidity allow. Beneficiaries should be told about this, since they may owe tax before receiving the money.
Does the three-year rule apply to capital gains as well as income?
Capital gains realised by the estate on selling assets are assessable to the estate under the same section 99/99A framework, so the same three-year timing consideration applies. Making beneficiaries presently entitled to capital is generally harder to establish than for income, often requiring specific will provisions or trustee resolutions.
