Republicans Push to Kill the ‘Inflation Tax’ on American Investments — Trump Administration Urged to Tax Real Gains, Not Phantom Profits

WASHINGTON — Republican lawmakers and tax-policy advocates are renewing a push to change the way Washington taxes investment gains, arguing that Americans should not be forced to pay capital-gains taxes on increases in value caused merely by inflation.

The proposal is straightforward: adjust an investment’s original cost for inflation before calculating the taxable gain.

Supporters say the reform would stop the federal government from effectively taxing Americans twice—first as inflation erodes the purchasing power of their dollars, and again when the tax code treats inflation-driven increases in asset prices as genuine profits.

“The tax code treats inflation like it is income, which it isn’t,” Cato Institute tax expert Adam Michel told The Epoch Times as the proposal received renewed attention this week.

For millions of Americans who spent decades building savings, buying homes, investing in businesses or putting money into the stock market, the distinction can translate into serious money.

Washington Taxes Nominal Gains — Not Just Real Wealth

Under current federal law, capital gains generally are calculated using the nominal difference between what someone paid for an asset and what they later received when selling it.

Inflation isn't generally subtracted from that calculation.

Consider an investor who bought an asset for $100 and eventually sold it for $300. Current law generally treats the $200 difference as the capital gain, even though some of that increase may simply reflect the declining purchasing power of the dollar.

Inflation indexing would increase the investor's cost basis to account for inflation and tax only the remaining real economic gain.

That is why supporters call the existing system an “inflation tax.”

Americans can watch Washington-generated inflation drive prices higher, only to have Washington later treat part of those higher nominal prices as taxable investment income.

Republicans want that changed.

Republicans Tell Treasury: End the Tax on ‘Phantom Gains’

The campaign has been building throughout 2026.

Republican Sens. Ted Cruz of Texas and Tim Scott of South Carolina have pressed Treasury Secretary Scott Bessent to index capital gains for inflation. House Republicans have joined the effort, including members of the Congressional Real Estate Caucus and Republican Study Committee.

The House lawmakers argued that the existing system particularly hurts Americans who hold property for long periods.

As inflation pushes nominal home values upward, a homeowner can eventually face taxation on appreciation that does not represent an equivalent increase in real purchasing power.

Republicans argue this can discourage owners from selling, reduce housing-market mobility and keep properties off the market when the country already faces tight housing inventories.

Their message to the Trump administration is simple:

Americans should pay taxes on actual investment profits—not inflation manufactured into the price of an asset.

Trump Treasury Could Become the Battleground

The biggest question is not how indexing would work.

It is who has the legal authority to do it.

Some Republican lawmakers and outside advocates argue that the Treasury Department already possesses sufficient authority to redefine how an asset's cost basis is calculated and could therefore implement inflation indexing administratively.

A coalition supporting the change formally urged President Donald Trump earlier this year to use executive authority to make the adjustment.

But that interpretation is contested.

A 1992 Justice Department legal opinion concluded that Treasury could not unilaterally index capital gains because existing federal law calculates basis using nominal costs. The Supreme Court's 2024 decision overturning the Chevron doctrine could create an additional obstacle for an administration attempting to defend a broad reinterpretation of tax law in court.

That means an executive move by the Trump administration would almost certainly face a legal challenge.

Congress could eliminate much of that uncertainty by explicitly changing the law.

Cruz has already introduced legislation—the Capital Gains Inflation Relief Act—that would permit individual taxpayers to inflation-adjust the basis of qualifying assets held for more than three years.

This Isn’t Just About Wall Street

Opponents frequently characterize capital-gains tax reductions as policies primarily benefiting wealthy investors.

But capital assets extend far beyond hedge funds and Wall Street trading desks.

They include stocks, businesses, real estate and other property accumulated by Americans over decades.

The Republican lawmakers pressing Treasury have placed particular emphasis on homeowners and long-term real-estate investors, arguing that inflation taxation can discourage property sales and reduce housing supply.

Supporters also argue that eliminating taxation on inflationary gains would encourage Americans to save and invest rather than penalizing them for holding assets over long periods.

That is fundamentally a pro-growth argument.

America needs citizens willing to invest capital, build businesses, purchase property and put savings into productive enterprises.

Punishing long-term investment because the dollar lost purchasing power makes little economic sense.

Critics Warn About the Deficit — and Executive Power

There are legitimate counterarguments.

The Bipartisan Policy Center cites estimates suggesting prospective inflation indexing could reduce federal revenues by roughly $170 billion over a decade, while applying the change retroactively could produce a substantially larger fiscal impact.

Critics also argue that adjusting capital gains alone would create inconsistencies because inflation affects other areas of investment income, deductions and losses.

The Tax Foundation similarly notes that while indexing would remove taxation on inflation-driven gains, changing capital gains without addressing other inflation-related tax distortions could create new opportunities for tax avoidance.

And there remains the constitutional question.

Even Americans who favor lower taxes should care about whether major tax policy changes are made through lawful authority.

If Congress needs to act, Republicans should put the proposal into legislation and force lawmakers to vote on it.

Americans Shouldn't Pay Taxes on Washington’s Inflation

The broader principle is difficult to ignore.

Inflation does not make Americans richer simply because the dollar price attached to their property rises.

A house worth $300,000 years ago and $400,000 today has nominally gained $100,000. But if a substantial portion of that increase merely reflects the dollar becoming less valuable, treating every dollar of appreciation as new economic wealth exaggerates the owner's real gain.

Washington already recognizes inflation elsewhere in the tax code.

Federal income-tax brackets and numerous other tax provisions are routinely adjusted so inflation alone does not automatically push Americans into higher tax burdens.

Applying the same principle to capital gains deserves serious consideration.

President Trump and congressional Republicans have made lower taxes, domestic investment and American economic growth central parts of their economic agenda.

Ending taxation on purely inflationary gains would fit squarely within that philosophy.

But it should be done in a way that can survive the courts and provide investors with lasting certainty.

Americans should pay taxes on money they actually make—not on imaginary profits created because Washington allowed their dollars to buy less.

That isn't a Wall Street loophole.

It's basic tax fairness.
