Tax Reform Act of 1986: Lessons for Australian Tax Policy

Tax reform is a recurring topic in Australia, with ongoing debates about fairness, simplicity, and economic growth. As policymakers and the public consider the future of Australia’s tax system, it’s useful to look at major reforms overseas. One of the most significant was the United States’ Tax Reform Act of 1986 (TRA86), which aimed to simplify the tax code and make it fairer. While Australia’s tax system is different in many respects, the lessons from TRA86 remain relevant as we approach another period of potential change.

Australia’s tax landscape is shaped by issues such as bracket creep, housing tax concessions, and the treatment of superannuation. With discussions about tax reform gaining momentum, reflecting on the experience of TRA86 can help inform decisions about how to create a system that is both efficient and equitable.

The Tax Reform Act of 1986 was a major overhaul of the US federal tax system. Its main objectives were to simplify the tax code, broaden the tax base, and make the system fairer. The reform was notable for its bipartisan support and for attempting to be revenue neutral—meaning it aimed to raise the same amount of revenue, but in a different way.

Key Features of TRA86

• Broadening the Tax Base: Many deductions, exemptions, and loopholes were removed, so more types of income became taxable.
• Lowering Tax Rates: The number of tax brackets was reduced, and the top marginal rates for individuals and corporations were lowered.
• Simplification: With fewer brackets and deductions, the tax code became easier for many people to understand and comply with.
• Focus on Equity: The changes aimed to distribute the tax burden more evenly, reducing opportunities for tax avoidance.

TRA86 is often cited as a rare example of comprehensive tax reform achieved through cross-party cooperation. The process involved extensive negotiation and compromise, with the goal of creating a fairer and simpler system.

Immediate Outcomes

Following its introduction, TRA86 was seen as a success in many respects. The tax system became simpler for many households, and the distribution of tax burdens shifted. By closing loopholes and broadening the base, the reform reduced some of the opportunities for aggressive tax planning.

Long-Term Developments

Over time, however, the simplicity achieved by TRA86 began to erode. New deductions and credits were gradually added back into the system, and the tax code became more complex again. Despite this, TRA86 is still remembered for showing that large-scale, bipartisan tax reform is possible and can deliver meaningful change.

Influence on Other Countries

The principles behind TRA86 influenced tax reforms in other countries, including Australia. In the years following TRA86, Australia undertook its own reforms, such as changes to income tax rates and the introduction of the Goods and Services Tax (GST). The emphasis on broadening the base and lowering rates has continued to inform tax policy discussions.

As Australia considers potential changes to its tax system, several lessons from TRA86 are worth keeping in mind:

1. Broadening the Base and Lowering Rates

One of the main achievements of TRA86 was to broaden the tax base while lowering marginal rates. For Australia, this could mean reviewing existing deductions, exemptions, and concessions to ensure the system is fair and sustainable. Reducing the number of special provisions can help make the system simpler and more transparent.

2. The Importance of Bipartisanship

TRA86 was only possible because of cooperation across the political spectrum. Major tax reform in Australia is likely to require similar collaboration. Building broad support can help ensure that changes are durable and widely accepted.

3. Simplicity and Transparency

A simpler tax system is easier for individuals and businesses to navigate. Reducing complexity can also lower compliance costs and make it harder for special interests to secure favourable treatment.

4. Ongoing Vigilance

Even well-designed reforms can become complicated over time as new provisions are added. Regular review and adjustment are necessary to maintain the benefits of reform and prevent the system from becoming unwieldy.

Australia faces several challenges that echo the issues addressed by TRA86:

• Bracket Creep: As incomes rise with inflation, more people move into higher tax brackets, increasing their tax burden unless thresholds are adjusted.
• Housing Tax Concessions: Policies such as negative gearing and capital gains tax discounts have been debated for their impact on housing affordability and fairness.
• Superannuation Tax Treatment: The concessional tax treatment of superannuation is under review, with questions about its long-term sustainability and equity.
• Balance Between Direct and Indirect Taxes: Australia relies heavily on income tax, with ongoing debate about the role of consumption taxes like the GST.

Simplifying Tax Brackets

Reducing the number of income tax brackets could make the system easier to understand and administer. However, any changes would need to consider the impact on different income groups and overall revenue.

Reviewing Deductions and Concessions

A comprehensive review of deductions and concessions—such as those for investment properties or superannuation—could help ensure the tax system is fair and efficient. Removing or limiting some concessions may broaden the base and allow for lower rates.

Maintaining Revenue Neutrality

Like TRA86, any major reform in Australia could aim to be revenue neutral, shifting the tax burden rather than increasing it. This approach can make reform more politically acceptable and focus attention on fairness and simplicity.

Ensuring Ongoing Review

Regular assessment of the tax system can help prevent the gradual reintroduction of complexity. Independent reviews and public consultation can play a role in keeping the system on track.

For Policymakers

• Engage Broadly: Consult with a wide range of stakeholders, including business, community groups, and tax experts.
• Communicate Clearly: Explain the goals and expected outcomes of reform to build public understanding and support.
• Monitor Outcomes: Track the effects of changes and be prepared to make adjustments if needed.

For Taxpayers

• Stay Informed: Keep up to date with proposed changes and understand how they might affect your situation.
• Seek Professional Advice: Tax professionals can help interpret new rules and suggest strategies for compliance.
• Use Technology: Digital tools can make tax filing and record-keeping easier, especially as rules change.

Australia has an opportunity to learn from the experience of TRA86 as it considers its own tax reform. The key messages are the value of simplicity, fairness, and broad-based support. While no system is perfect, regular review and a willingness to adapt can help ensure the tax system meets the needs of all Australians.

What was the main purpose of the Tax Reform Act of 1986?

The main goal was to simplify the US tax code, broaden the tax base, and make the system fairer, without increasing overall tax revenue.

How did TRA86 influence tax reform in Australia?

TRA86 demonstrated that comprehensive, bipartisan tax reform is possible and influenced Australia’s own approach to broadening the tax base and reviewing tax rates.

What are some current challenges in Australia’s tax system?

Key challenges include bracket creep, the complexity of housing and superannuation concessions, and balancing direct and indirect taxes.
