US Government Revenue – Tariffs and their Limits: How economically sensible are they really?

Tariffs as a Source of U.S. Government Revenue: An Analysis of Their Importance and Impact

Tariffs play a minor role in the United States compared to other sources of government revenue. In 2023, revenue from tariffs and fees amounted to approximately $80 billion, accounting for just 1.8% of the U.S. government's total revenue. For comparison, the income tax brought in around $2.2 trillion in the same year, which accounts for about half of all government revenue. These figures make it clear that, despite their historical importance as a financing instrument, tariffs now play only a marginal role in the US budget.

Trump's proposals and their feasibility

Donald Trump has repeatedly emphasized the importance of tariffs throughout his political campaigns, highlighting them as a key economic and political tool. His suggestions ranged from moderate adjustments to radical ideas. For example, he suggested using additional customs revenue to finance tax cuts or pay off debt. In one particularly controversial proposal, he even floated the idea of ​​completely replacing income taxes with tariffs.

However, this idea was met with widespread criticism from economists and financial experts. The reason for this lies in the sheer discrepancy between revenues from customs duties and those from income taxes. To truly replace the income tax would require extremely high tariff rates - estimates suggest a universal tariff rate of around 58% to 70% would need to be imposed on all imports to match income tax revenue levels. However, such a scenario is not considered economically viable as it would have far-reaching negative consequences.

On the one hand, such a high tariff rate would massively increase the prices of imported goods, which would significantly affect the purchasing power of consumers. On the other hand, such tariffs could lead to a drastic decline in international trade as both imports and exports would be severely restricted. This would not only reduce the potential revenue from the tariffs themselves, but also slow down overall economic growth.

Economic Impact of Tariffs

Costs for consumers

Tariffs typically have a direct impact on consumers because they result in higher prices for imported goods. Companies that rely on imports often pass on the additional costs to end customers. An example of this is Trump's previous tariffs on washing machines: studies show that this measure led to an average price increase of 12%. For US households, this meant an additional financial burden in everyday life.

The impact of higher prices is particularly noticeable on low-income households, as they have to spend a larger share of their income on consumer goods. This means that it is precisely those population groups that are already economically disadvantaged that bear the brunt of such measures.

Economic distortions

High tariffs can also lead to significant economic distortions. They typically reduce trade volumes and reduce the amount of imported goods. Although this can promote sales of domestic products in the short term, it can have negative consequences in the long term. Companies that rely on international supply chains could find their competitiveness restricted by higher import costs.

In addition, high tariffs could also lead to companies moving their production sites abroad to avoid the additional costs. This, in turn, could jeopardize jobs in the US and slow economic growth.

Retaliation and trade wars

“Retaliation” is an English term that literally means “retaliation” or “counter-strike”. Retaliation is often used, particularly in international trade law. It means that a country (or an economic entity such as the EU) takes punitive measures - e.g. B. through tariff increases or import bans - imposed against another country in response to protectionism, unfair trade practices or violations of trade agreements.
Example: If a country illegally increases its import tariffs, the affected country could also impose tariffs on certain of the former's products as retaliation.

Another risk of high tariffs is the possible countermeasures of other countries. When a country increases its import tariffs, trading partners often respond with counter-tariffs on that country's exports. This may escalate into a trade war in which both sides suffer economic losses.

A prominent example of this is the trade conflict between the USA and China during Trump's presidency. Both countries imposed high tariffs on a variety of products. The result was not only rising prices for consumers and businesses in both countries, but also a slowdown in global economic growth.

The limited role of tariffs as a source of revenue

The analysis clearly shows that tariffs are not a suitable alternative to income taxes as the US government's main source of revenue. Their income is comparatively low and is far from enough to cover the needs of the state budget. They are also associated with significant economic side effects.

While Trump has viewed tariffs as a central element of his economic policy, their actual effectiveness remains limited. Although they can serve as a control tool in certain situations - for example to protect certain industries or to promote domestic production - their role as a reliable source of income is severely limited.

Historical Perspective: The Development of Customs Policy

Tariffs have a long history in the United States and played a central role in government financing, particularly in the 19th century. In fact, before the introduction of the income tax in 1913, they were the federal government's most important source of revenue. At that time they not only served fiscal purposes, but also to protect domestic industries from foreign competition.

However, with increasing globalization and the growth of international trade, the meaning of tariffs has changed significantly. Today they are often caught between economic efficiency and political objectives. While some politicians – like Trump – see them as a way to advance national interests, economists often emphasize their negative impact on trade and prosperity.

Tariffs are a limited tool

Tariffs are a complex economic tool with limited potential as a revenue source for modern economies like the United States. Their introduction or increase should always be carefully considered as they can have far-reaching consequences for consumers, businesses and international trade.

Trump's idea of ​​using tariffs to replace income taxes may seem politically popular, but it is neither practical nor economically viable. Instead, governments should look for balanced solutions that both ensure fiscal stability and promote economic growth - without creating unnecessary burdens for citizens and businesses.

In an increasingly globalized world, balancing national interests with the demands of international trade remains a challenge for policymakers. The discussion about tariffs exemplifies the areas of tension in modern economic policy: between protectionism and free trade, between short-term political gains and long-term economic prosperity.
