The Case for Flat Tax: Insights from India’s GST

My thoughts are just thoughts, but they stem from having a client in India who owes me money and for whatever reason is having difficulty sending it outside India. So I thought why not open a company in India and then bring the money back home to America. A lot of research and many Chartered Accountants & Lawyers discussions later I was perplexed on how crazy PM Modi’s GST system was. I was furious at how rigid it was and how much they would collect off of me. Knowing rightfully this money was earned in the states and they had no right to it. But if an Indian company makes money they MUST pay Indian tax. I thought to myself thats GENIUS! You can’t get out of it. It almost seems full proof. And here I share my findings, my thoughts and my scratch work projections:

Imagine a world where tax day isn’t filled with endless forms, complex deductions, and confusion. What if instead of our convoluted tax system, the United States implemented a simpler system, one modeled after India’s Goods and Services Tax (GST) framework?

In India, they follow a straightforward tax model: an 18% GST is levied on most goods and services, and there’s a system of Tax Deducted at Source (TDS) that ensures taxes are collected on income at various stages. This simplicity is something worth considering as we reevaluate our own tax laws.

Scratch Work Summary:

1.  Total consumer spending in 2023: $18 trillion
2.  Apply 18% GST: $3.24 trillion (but adjusted for likely exemptions to $2.88 trillion)
3.  TDS could generate $2.6 trillion based on improved collection efficiency.
4.  Total potential revenue: $5.48 trillion, slightly more than the current tax revenue.

This is a high-level estimate, and actual figures would vary based on exemptions, the efficiency of the tax collection system, and behavioral changes in spending. But shouldn’t this be food for thought?

The Complexity of the U.S. Tax Code

Our current tax code is over 70,000 pages long. It’s filled with deductions, credits, and loopholes that, while intended to provide fairness, create confusion for most Americans. From the standard deduction to itemizing for medical expenses, retirement contributions, and more, it’s a daunting task for the average taxpayer. Accountants thrive, but the rest of us suffer through weeks of preparation and stress.

It’s not just about filing your taxes either—it’s about understanding where your money is going. The entire process feels opaque. The question many of us ask is: Could it be simpler?

The GST Model: How India Does It

India’s Goods and Services Tax (GST) model, introduced in 2017, is a unified system where most goods and services are taxed at a flat rate of 18%. There are certain categories with lower rates for essential items and higher rates for luxury goods, but for the most part, it’s transparent and straightforward.

With GST, there’s a clear understanding of how much tax is levied on every purchase. The added system of TDS ensures that taxes are collected at the source for income, helping to minimize tax evasion.

How Would This Look in the U.S.?

Imagine a similar system here in the U.S. Instead of facing hundreds of different tax brackets, credits, and deductions, we could have a flat rate—say, 18%—on all goods and services. No more complicated income tax filings. For businesses, this would be a significant relief from compliance burdens. For individuals, tax returns would be straightforward, if even necessary.

Furthermore, with a TDS-like system, taxes could be deducted at the source for all forms of income. This means you wouldn’t need to worry about underpaying taxes throughout the year or facing an unexpected bill come April.

The Benefits:

• Simplicity: A single rate for most purchases would eliminate the guesswork and stress associated with our current tax system.

• Transparency: Everyone would understand exactly how much they are being taxed, and there would be fewer surprises.

• Compliance: A simpler system would likely lead to greater compliance, as taxpayers would no longer need to navigate confusing deductions or fear making costly errors.

• Reduced Tax Evasion: With TDS, taxes are collected at the source, making it harder to evade taxes and increasing overall revenue collection.

The Challenges:

Of course, no system is perfect. A GST-like system would also have its challenges:

• Revisiting Social Welfare: Many of the deductions and credits we have today are aimed at social equity. How would we continue to support low-income households, students, and retirees? A flat tax rate might disproportionately affect lower earners, requiring new solutions such as targeted rebates or subsidies.

• Transition: Shifting from our current model to a GST system would be a monumental task. It would require buy-in from states, as sales taxes would likely need to be reworked or integrated into the new model.

Is It Time for a Change?

At its core, this idea is about one thing: making life easier for taxpayers. We can debate the finer points of deductions and fairness, but the truth is that most Americans would benefit from a tax system they can actually understand.

India’s GST may not be perfect, but it represents a major step toward simplification and transparency. What if we took a page from their playbook?

It’s time to consider radical change. A flat, transparent tax system—simplified for all Americans—could be the way forward.

To estimate how much revenue the U.S. could generate with a simplified GST system, we’ll need to calculate total consumer spending and estimate potential revenue based on an 18% tax on all goods and services, similar to India’s model. Here’s how we could approach it step by step:

Step 1: Calculate Total Consumer Spending in 2023

According to the U.S. Bureau of Economic Analysis (BEA), total consumer spending (personal consumption expenditures) is a key economic indicator. In 2023, consumer spending was projected to be around $18 trillion. This includes all goods and services purchased by individuals in the economy.

Step 2: Apply an 18% GST

If we assume a flat 18% tax on all consumer expenditures (excluding those goods and services that might be exempt, like certain essentials, healthcare, or education), we can calculate the potential revenue.

Total Revenue from GST = Total Consumer Spending x GST Rate

Using the $18 trillion estimate:

Total Revenue from GST = 18 trillion x 0.18 = 3.24 trillion dollars

Step 3: Compare to Current Tax Revenues

To put this in perspective, according to the Congressional Budget Office (CBO), total federal tax revenue for 2023 is estimated to be about $4.8 trillion, which includes income taxes, payroll taxes, corporate taxes, and other sources. A GST alone would generate about $3.24 trillion, which is a significant portion of that amount but still short of fully replacing all current tax revenues.

Step 4: Adjust for Exemptions or Special Categories

In practice, not all consumer spending would likely be taxed at 18%. Essential goods like groceries or healthcare might be taxed at a lower rate or exempted altogether. To adjust for this, we can assume that only 80% of consumer spending would be subject to the full 18% GST. This gives:

Adjusted Revenue = 18 trillion x 0.8 x 0.18 = 2.88 trillion dollars

Step 5: Add TDS for Additional Revenue

The TDS (Tax Deducted at Source) system could further contribute revenue, particularly by capturing income taxes more efficiently. Let’s estimate TDS could contribute a similar share as current income taxes, which in 2023 were about $2.5 trillion. However, with the simplification of the system, collection rates might improve slightly, so we can conservatively estimate that TDS could bring in an additional $2.6 trillion.

Total Estimated Revenue (GST + TDS)

By combining GST and TDS:

Total Estimated Revenue = 2.88 trillion (GST) + 2.6 trillion (TDS) = 5.48 trillion dollars

This means that with an 18% GST and a TDS system, the U.S. could potentially generate $5.48 trillion in revenue, which would slightly exceed the current tax revenue estimate of $4.8 trillion.

Scratch Work Summary:

1.  Total consumer spending in 2023: $18 trillion
2.  Apply 18% GST: $3.24 trillion (but adjusted for likely exemptions to $2.88 trillion)
3.  TDS could generate $2.6 trillion based on improved collection efficiency.
4.  Total potential revenue: $5.48 trillion, slightly more than the current tax revenue.
