ACT payroll tax: $2M threshold, 6.85% rate and ACT Revenue Office lodgement

ACT's high threshold + high rate — economically purposeful

The ACT's $2M threshold is the highest in Australia, well ahead of South Australia's $1.5M and NT's $1.5M, and meaningfully higher than NSW's $1.2M. Combined with the 6.85% flat rate (highest single rate in Australia), the ACT's framework reflects deliberate policy: shield small-to-mid Canberra private-sector employers (who otherwise compete against Commonwealth pay scales for talent) while collecting meaningful revenue from large above-threshold employers — predominantly federal government departments and the bigger Canberra service-sector employers (banks, telcos, defence contractors with Canberra offices).

Practical effect: a Canberra IT consultancy with $1.9M wages pays zero payroll tax (under $2M threshold). The same consultancy with $2.5M wages pays 6.85% on $500K = $34,250. The marginal rate at the threshold cliff edge is significant, and the 6.85% effective rate on the portion above is the highest in Australia — a real cost for ACT-based scaleups.

Public-sector employer concentration and Commonwealth carve-outs

The ACT's economy is dominated by the Australian federal government — Department of Defence, ATO, Centrelink/Services Australia, DFAT, Treasury, plus broader Australian Public Service departments concentrated in Canberra. These Commonwealth employers do not pay ACT payroll tax (Commonwealth entities are exempt from State and Territory taxation under s. 114 of the Australian Constitution), but Commonwealth contractors and labour-hire companies servicing federal departments DO pay payroll tax on their wages.

This creates an unusual ACT-specific compliance scenario: a labour-hire company supplying contractors to ATO and Defence is liable for payroll tax on the contractors' wages, while the federal departments themselves pay nothing. The labour-hire margin must absorb the 6.85% (or pass it back to the Commonwealth client in the contract rate). HelloBooks tracks labour-hire arrangements as a distinct category for ACT employers, helping margin analysis on Commonwealth contracts.

Monthly returns, ACT Revenue Online, and federal interaction

Monthly returns are due by the 7th of the following month via ACT Revenue Online. The June return is replaced by the annual reconciliation due 21 July covering the full prior financial year. The ACT's harmonised model means definitions of taxable wages, fringe benefits, and grouping align with NSW/VIC/QLD — a multi-jurisdiction Canberra employer with branches in Sydney files consistent definitions across both Revenue NSW and ACT Revenue Office returns. HelloBooks runs both jurisdictions on the same payroll data.
