The AEC disclosure threshold explained: counting per donor, not per gift

Updated 22 July 2026. This article was first published on 3 June 2026, before the AEC's transitional rules took effect on 1 July 2026. It has been corrected: the reporting period, the lodgement dates and the description of what changes in 2027 were all superseded by those rules and have been rewritten. The counting principle the article is about is unchanged.

A treasurer at a small advocacy group sits down before the annual return deadline to file the disclosure return and finds that the same supporter gave three times during the financial year: $7,000 in August, $6,000 in February, $5,000 in April. None of those amounts crossed the disclosure threshold on its own. Added together they did, and the rule that follows is the one organisations most often miss: every gift from that donor across the financial year now has to be disclosed, including the small ones, regardless of size. The arithmetic that decides whether a return is short or long has already happened in the database. Reading it correctly at the end of the year is downstream of how the records were kept months earlier.

The disclosure regime reads as fiddly the first time, and it stops being fiddly the moment an organisation changes how it counts. The threshold is high enough on paper that most teams never feel it bite. The same record-keeping that prepares an organisation for the year it does bite also makes the return at the end of every ordinary year fast to produce.

The threshold, and the period it now applies to

The federal disclosure threshold is more than $17,300. It applied to the financial year 1 July 2025 to 30 June 2026, having moved up from $16,900 the year before.

The period is where care is needed, because it is no longer a financial year. The AEC's transitional rules have applied since 1 July 2026 and create a six-month reporting period running 1 July 2026 to 31 December 2026, with the threshold held at $17,300 for it. There is no 2026-27 financial-year return. Returns for that six-month period, including donor returns, are due by 11 March 2027.

That has a practical consequence worth stating plainly: an organisation accumulating totals towards a 1 July 2026 to 30 June 2027 year, and planning to lodge in November 2027, is counting against a period that no longer exists and will miss a March 2027 lodgement.

The threshold has historically been indexed with effect from 1 July each year against the consumer price index, but no increase took effect on 1 July 2026. From 1 January 2027 the indexation rule itself changes, to each 1 January that follows a general election. Guidance written for an earlier year is not safe to use without checking both the current figure and the current period.

Most organisations look at $17,300 and conclude they are nowhere near it. That is usually true for any single gift. Once a period of giving from one donor is added up the picture changes, because the threshold is an aggregate.

A per-donor, per-recipient total across the year

The AEC's annual donor guidance defines an annual donor as a person or entity that makes one or more donations totalling more than the disclosure threshold during a financial year. That wording describes the 2025-26 return, which is still open; the aggregation window then shortens with the regime. Totals run against the financial year to 30 June 2026, then against the six-month transitional period to 31 December 2026, then against the calendar year from 1 January 2027. What does not change is the principle: the threshold is a total, not a single-transaction limit. A donor who gives $9,000 in October and $9,000 in February has crossed the threshold once the second gift is recorded, even though neither gift alone would have triggered anything.

What follows from crossing it tends to catch operations teams out. The AEC guidance is explicit: if the total of gifts from a donor to a political party, significant third party, or member of Parliament exceeds the disclosure threshold, then all gifts made to that recipient by that donor must be disclosed, regardless of value. A $20 deposit that arrived in July is now part of the return because of a $10,000 gift that arrived nine months later.

The unit of disclosure is the donor-recipient relationship for the year. An organised return depends on counting it that way from the start.

What this changes about how to count

The practical effect is that the moment to tag a gift is when it is recorded, not at the end of the year. A donor's gifts need to land against a single donor identity so the running total is correct: three slightly different spellings of the same name in three different campaign batches produce three running totals that each look harmless. The same applies to associated entities and entities controlled by the same person, though the test for that is more involved and warrants advice rather than guesswork.

What counts as a gift is also broader than the database often suggests. The AEC's financial disclosure guidance treats a service provided for no consideration or for inadequate consideration as a gift, so support that never shows as money still counts, and the companion piece on what counts as a gift covers that in detail. A donor's total for the period is built from cash, non-cash benefits, and in-kind support combined.

For most small organisations the per-donor total across the year never reaches the threshold, and the work matters in the year it does. A real example: an operations lead at one organisation, working through the return in the days before the deadline, found a stream of major gift donations that had been left out and had to roll them in right up to lodgement. The fix is upstream: one donor identity, one running total, visible the moment a gift is recorded.

The piece on the donation revenue most orgs leave on the table makes a parallel point from the fundraising side: the same donor identity the second-gift ask depends on is the donor identity the disclosure return depends on. The work to resolve duplicates pays in two places.

The 2027 reforms move the goalposts

The shape of the question changes again on 1 January 2027. The Electoral Legislation Amendment (Electoral Reform) Act 2025 introduces a federal disclosure threshold of $5,000, indexed on each 1 January following a general election. It adds donation caps: $50,000 per donor per recipient, $250,000 per donor per state or territory, $1,600,000 per donor overall, plus separate $50,000 caps for a by-election and for a Senate-only election that do not consume the annual cap. Those are the amounts the AEC publishes as at 1 January 2027. The caps are indexed on 1 January each year and the AEC publishes the indexed amounts before then, so confirm the operative figure for the calendar year you are planning against rather than carrying these forward. It also caps electoral expenditure, which is easy to miss in a discussion framed around donations: as at 1 July 2026, $90 million federally for registered parties with $800,000 per division, and $11.25 million for third parties, significant third parties and associated entities with a $100,000 divisional cap, all indexed on that same 1 January cycle.

Disclosure timing changes too, and not only during elections. Outside an election period a donation disclosure notice is due by the 21st day of the following month. During an election period the window is 7 days. In the expedited notice period around polling day the two sides diverge: recipients have 24 hours, while donors keep the 7 days. The year-round monthly obligation is the one an operations team has to build for, but that 24-hour recipient window is the one most easily missed.

Two changes matter most for how an organisation counts. The threshold drops from a moving figure near $17,000 to $5,000, which means many donors who never approached the current threshold will cross the reformed one within a single half of the year. And the calendar year replaces the financial year as the unit the running total is measured against, for those entities that still lodge an annual return. Donors are not among them: from 1 January 2027 a donor's obligation is a donation disclosure notice rather than an annual return, so a donor-side reader planning for a calendar-year annual return is preparing for the wrong thing.

The caps are a different layer. Disclosure obligations describe what has to be reported. The caps describe what is allowed to be received in the first place. A $60,000 aggregate from one donor to one party across a cap period is not just disclosable, it is over the per-recipient cap. That period is the calendar year in an ordinary year, but an election year carries a second reset, which the companion piece on cap timing works through. Exceeding a cap does not void the gift automatically: the donor or recipient must take acceptable action, such as returning the excess, within 6 weeks of becoming aware, and civil penalty exposure follows if they do not. From 1 January 2027 a recipient organisation needs the running total in two places, against disclosure and against caps, supported by the same underlying records.

A counting habit that scales

The discipline that copes well with the current rules and the reformed ones is identical at the data layer. The basics are familiar: a single donor identity per real person or entity applied at the moment of gift; a running total per donor per recipient visible without a spreadsheet exercise; a tag that records whether the gift was cash, non-cash benefit, or in-kind, because all three sit on the same per-year total; an audit trail linking each deposit to the donor identity it was attributed to. None of that is law. It is the upstream record-keeping that turns the disclosure return at the end of the year into a query against clean data rather than a reconstruction.

An organisation that does this well reaches 1 January 2027 with the right shape of records already in place. The dates, though, are not a single roll-over. There are three lodgements in sequence: the 2025-26 annual return, due 17 November 2026 for annual donors, members of parliament and senators, and third parties, or 20 October 2026 for registered parties, their state and territory branches, significant third parties and associated entities; then the six-month transitional return covering 1 July to 31 December 2026, due 11 March 2027; then the new scheme from 1 January 2027, under which entities that still lodge annually report on the calendar year eight weeks after it ends, and donors lodge donation disclosure notices instead.

For a treasurer, the practical next step has two parts. The first is to reconcile donor identity in the database so the running totals against the $17,300 threshold are accurate today, counted against the transitional period ending 31 December 2026 rather than a financial year. The second is to confirm that incoming gifts are attributed by donor identity at the point of capture, so that when the $5,000 threshold takes effect on 1 January 2027 the same records carry over without rework.

This article is general information about the disclosure regime, not legal advice. Specific obligations depend on the kind of entity an organisation is and the kind of gift it received, and the AEC's financial disclosure guidance is the source to confirm any particular fact against.
