Should your local city council be required to get voter approval before increasing any taxes?

Portland Metro Chamber CEO Andrew Hoan has filed a lawsuit in Oregon Tax Court to block a 43% increase to the city's Arts Education and Access Tax. The chamber argues that the City Council lacks the legal authority to raise the tax without direct voter approval.

Why it matters

The outcome of this legal challenge could establish a precedent regarding whether the City Council can modify voter-approved measures without further ballot initiatives. A victory for the plaintiffs may also restrict the city's ability to propose future tax changes not explicitly authorized by the city charter.

The current arts tax generates approximately $12 million in annual revenue from taxpayers earning over $1,000 annually. The recent council vote to raise this fee includes an exemption for 40% of lower-income tax filers.

The players

Andrew Hoan

Andrew Hoan is the CEO of the Portland Metro Chamber and serves as the lead plaintiff in the legal challenge.

Robert Taylor

Robert Taylor is the Portland City Attorney who is defending the council's legislative authority regarding the tax.

Jamie Dunphy

Jamie Dunphy is the Portland City Council President who oversaw the initial proposal of the arts tax changes.

The details

The lawsuit contends that because the original 2012 measure was passed by 62% of voters, the council cannot unilaterally hike the rate. Conversely, City Attorney Robert Taylor maintains that the council holds concurrent legislative authority to adjust these measures to ensure the fund preserves its original purchasing power.

Voters approved the Arts Education and Access Tax in 2012.
Council President Jamie Dunphy proposed arts tax changes in April 2026.
Portland City Council voted to increase the arts tax in May 2026.
The lawsuit was filed in Oregon Tax Court on September 24, 2026.

Industry Dynamics

This dispute reflects a broader trend of conflict between city councils and business groups over the scope of municipal legislative authority regarding tax levies. The case hinges on whether voter-approved programs grant permanent mandates or remain subject to ongoing council modification.

Residents currently earning over $1,000 annually face a 43% increase to their yearly $35 tax burden if the policy stands. While 40% of low-income filers are exempt from the increase, the potential for future indexing to inflation could impact household budgets in the coming years.

The takeaway

Taxpayers should monitor the Oregon Tax Court proceedings to see if the city's enforcement of the increase is paused during litigation. Understanding the scope of the city charter can help residents better evaluate future ballot measures and council-led tax proposals.
