Trump’s Ultimate Tax Cut Proposal: Is Replacing Income Taxes with Tariffs Feasible?
In a surprising policy pitch, former President Donald Trump recently hinted at an idea that would radically reshape US tax policy: eliminating federal income taxes and replacing the revenue with tariffs on imported goods. Drawing inspiration from the economic approaches of the 1890s, particularly those of President William McKinley, Trump’s suggestion recalls a time when tariffs, not income taxes, largely funded the federal government. However, experts across the political spectrum have been quick to dismiss the feasibility of such a plan, citing substantial economic and logistical concerns.
This article delves into Trump’s proposition, its historical context, the potential economic impacts, and why many believe this radical shift would be challenging, if not impossible, to achieve.
A Return to McKinley-Era Tariff Policies
Trump’s vision is reminiscent of the 1890s, when high tariffs on imported goods funded federal expenses before the federal income tax was introduced in 1913. During President McKinley’s era, tariffs were the primary source of revenue, but critics of the time argued that they placed an undue burden on working-class Americans by inflating prices on consumer goods. This criticism laid the groundwork for the introduction of the federal income tax, intended to create a progressive tax system that would alleviate income inequality and ensure that wealthier Americans contributed a larger share.
Trump’s nod to this historical policy, therefore, is not just a call for lower taxes but a radical overhaul that would change how the US government funds its operations.
Would Tariffs Alone Be Enough to Replace Income Taxes?
Replacing the federal income tax with tariffs would require a massive increase in tariff rates. Today, tariffs contribute a mere 2% to federal revenue, while income and payroll taxes account for over 90%. According to the Congressional Budget Office (CBO), income taxes alone generated approximately $4.2 trillion in revenue in fiscal year 2024, whereas US imports amounted to about $3 trillion. The disparity is clear: even imposing extremely high tariffs on all imports wouldn’t come close to filling the gap left by eliminating income taxes.
Such a shift could, in fact, have unintended and severe economic consequences. High tariffs on foreign goods would likely increase costs for US consumers and businesses, potentially leading to inflationary pressure. In a globalized economy, these higher tariffs might prompt retaliatory measures from trade partners, leading to a trade war that could severely restrict the flow of goods to and from the United States. In the end, the impact on American consumers, who would face higher prices, and on businesses relying on global supply chains could be profound.
Experts Weigh In: “Economically Destructive” and “Mathematically Impossible”
Both conservative and liberal economists have expressed doubts about the economic viability of Trump’s proposal. In practical terms, raising tariffs to the levels needed to replace income tax revenue would be extraordinarily challenging, and experts agree that the US economy could face considerable harm as a result. The prospect of alienating trade partners with excessive tariffs also risks eroding global trade relationships, further reducing revenue rather than bolstering it.
Additionally, dismantling the income tax system would face stiff political opposition. Even with a Republican-controlled Congress, the wholesale elimination of income tax revenue would be difficult to justify given the negative implications for federal spending on essential programs, such as Social Security, Medicare, and defense. Lawmakers would face significant pressure from constituents who rely on these services, making it politically unfeasible to rely solely on tariffs.
Why Income Taxes Are Now Essential to Federal Revenue
The federal income tax system was introduced not only to provide a steady revenue stream but also to address concerns about economic inequality. With a progressive tax system, wealthier Americans pay a higher share of their income, which has been instrumental in funding the larger government services needed in a modern economy. By contrast, tariffs tend to function as a “regressive tax” that disproportionately affects lower-income individuals, as they raise prices on imported goods that are widely consumed.
Today, high-income earners account for a majority of income tax revenue. In 2020, for example, the top 20% of earners paid nearly 80% of all federal taxes. This progressive structure is foundational to the current system, allowing the government to support various social programs while reducing the financial burden on lower-income households. Eliminating the income tax would dismantle this structure, increasing the tax burden on low- and middle-income Americans through higher prices on essential goods.
Tariffs vs. Income Taxes: How They Shape the Economy
Switching from an income tax to a tariff-based system could drastically alter the landscape of the US economy, especially for businesses with international ties. Many companies that rely on imported goods would face higher costs, which could lead to price increases for consumers. Furthermore, companies operating globally could find it harder to compete, as retaliatory tariffs from other countries would make American goods more expensive abroad.
In a worst-case scenario, this shift could spark a global trade conflict, with countries imposing their own tariffs on American products. The consequences of such a trade war would extend far beyond lost revenue, potentially stifling innovation, reducing consumer choice, and causing job losses in export-dependent industries.
The Economic Realities: A Tax Shift with Few Supporters
Trump’s proposed elimination of income taxes in favor of tariffs may appeal to those who favor smaller government and lower taxes. However, the feasibility of this shift is limited by economic reality. Today’s federal budget relies heavily on income and payroll taxes, and a tariff-based system would not be able to bridge this revenue gap without causing severe inflation and potentially pushing the US into a damaging trade war.
Many experts argue that a mix of income and corporate taxes remains essential to fund modern public services, support social programs, and maintain infrastructure. Replacing income taxes with tariffs alone would likely lead to significant social and economic challenges, with lower-income Americans shouldering a disproportionate share of the burden.

A Bold Idea with Limited Practicality
While Trump’s call to eliminate income taxes in favor of tariffs is bold and rooted in historical precedent, it faces significant obstacles in the present-day economic landscape. The scale of revenue generated by income and payroll taxes today cannot realistically be matched by tariffs, especially without triggering far-reaching economic repercussions. The transition to a tariff-based system would not only increase costs for consumers but also risk destabilizing international trade relations.
Ultimately, Trump’s proposal serves as a provocative reminder of the ongoing debate around tax policy and economic growth. However, in a complex, interconnected global economy, maintaining a balanced and progressive tax structure remains crucial to sustaining federal programs and protecting economic stability.
