Could Trump's Tariffs Replace the Income Tax? Here's What Policy Experts Say

As former President Donald Trump mulls a potential second term, one of his signature economic policies has been the subject of much debate: tariffs. Trump has proposed sweeping tariffs on various countries, including a 60% tariff on Chinese imports and a 10% to 20% tariff on all imported goods. But could these tariffs replace the federal income tax, as Trump has suggested? Let's explore what policy experts have to say on the matter.

The Math Doesn't Add Up

Replacing the federal income tax with tariffs is mathematically impossible due to the significantly smaller tax base of imports compared to taxable income. The federal income tax raises about half of the nearly $5 trillion in revenue that the federal government collects, amounting to approximately $2.4 trillion annually. By contrast, tariffs bring in about 2% of federal revenue, totaling around $45 billion in 2021.

To replace the $2.4 trillion in income taxes with tariffs, a 75% tariff on America's $3.2 trillion in annual imports would be required. However, this is unrealistic, as it assumes that Americans would continue purchasing the same imports at nearly double the price. Moreover, increasing tariffs would likely prompt Americans to purchase fewer imported goods, canceling out at least part of the hoped-for revenues. Additionally, other nations may impose retaliatory tariffs on US exports, further reducing the potential revenue from tariffs.

Economic Consequences

Increasing tariffs would have significant economic consequences, as seen in the Trump administration's imposition of tariffs on Canada, Mexico, and China in 2018. The Budget Lab's analysis of the economic and fiscal implications of these tariffs found that:

* The proposed tariff package would put upward pressure on the PCE price level of 0.72-0.76% before consumer substitution, equivalent to a loss of purchasing power of about $1,250 on average per household in 2024.
* Even after consumers substitute, the level of PCE prices would still be persistently 0.6% higher in the medium-term, a loss in purchasing power of about $1,000 per household in 2024.
* The size of the US economy would be persistently 0.2% smaller in real terms in the medium-to-long run.

Political Consequences

Increasing tariffs would also have political consequences, as it would likely face opposition from both domestic and international stakeholders. Domestic industries that rely on imported goods and services would likely oppose the tariffs, as they would face higher costs and potentially reduced competitiveness. Foreign governments would likely retaliate against the US with their own tariffs, leading to a potential trade war and further economic harm.

The Verdict: Tariffs Can't Replace the Income Tax

Based on the analysis of policy experts and the data presented, it is clear that replacing the federal income tax with tariffs is not feasible. The significantly smaller tax base of imports compared to taxable income, the economic consequences of increased tariffs, and the political opposition they would face make this proposal unworkable. While tariffs can be a useful tool for addressing specific trade imbalances or protecting domestic industries, they cannot serve as a replacement for the federal income tax.

As former President Trump considers a potential second term, it is crucial for him and his administration to engage in a thoughtful and realistic assessment of the economic policies they propose, ensuring that they are grounded in evidence and supported by a broad coalition of stakeholders. By doing so, they can help to create a more prosperous and secure future for all Americans.
