Why Congress Won't End the Income Tax

President Trump has repeatedly floated a headline-grabbing idea: that tariff revenue could eventually replace — or at least “substantially replace” — the modern federal income tax. He’s said versions of this on the campaign trail, in interviews, and in major addresses, arguing Americans might someday “not even have income tax to pay.”

For filers drowning in W-2s, 1099s, and April deadlines, that pitch lands. For Capitol Hill, it’s a different story. Scrapping the income tax isn’t a White House memo — it’s a congressional heavy lift. And sitting in the middle of that fight is an industry that makes billions precisely because Americans still have to file: TurboTax-maker Intuit, H&R Block, and the broader tax software lobby.

What Trump is actually proposing

The concept is a throwback. For much of the 19th century, tariffs and excise taxes funded the federal government. The modern income tax arrived with the 16th Amendment (1913) and grew into the government’s main cash register.

Trump’s version pairs aggressive tariffs with the suggestion that import duties could someday fund government the way wage and investment taxes do now — or at least allow deep cuts so ordinary workers pay little or nothing.

Two realities cut against a quick “end of the income tax” narrative:

1. Only Congress can rewrite the Internal Revenue Code. The president can set trade policy within legal limits and propose budgets, but repealing individual income tax requires legislation.
2. The revenue gap is enormous. Individual income taxes bring in on the order of trillions over a few years. Customs duties — even at historically high recent levels — have been a fraction of that. Economists across the spectrum have argued that tariffs cannot mathematically replace income-tax receipts without rates so high that imports (and the tariff base itself) collapse.

So the politics aren’t just “yes or no to a viral idea.” They’re “who votes to blow a multi-trillion-dollar hole in the budget, and what replaces it?”

Why Congress is unlikely to vote for a full repeal

Members of Congress face pressures that go far beyond any one industry:

• Budget and entitlements: Income taxes help fund defense, interest on the debt, and the rest of discretionary government. Payroll taxes are separate (Social Security/Medicare), but a world with no income tax still needs a politically acceptable replacement.
• Distribution fights: Tariffs tend to hit consumers through higher prices. Replacing progressive income taxes with import taxes shifts who pays — a nonstarter for many Democrats and a problem for some Republicans in manufacturing and retail districts.
• Narrow majorities: Big tax rewrite bills die in committee, stall in the Senate, or get watered down into credits and temporary cuts. Full repeal is the hardest version of hard.

That’s the institutional wall. Layered on top is a quieter, well-funded interest group with a simple business model: as long as Americans must file income tax returns, someone gets paid to help them do it.

The tax software lobby has skin in the game

Intuit (TurboTax), H&R Block, TaxAct’s corporate parents, and similar firms don’t profit from abstract patriotism — they profit from complexity, deadlines, and the annual ritual of Form 1040.

If there were no individual income tax to prepare, the consumer tax-prep market would shrink dramatically. Even a “substantially replaced” system that left only a narrow residual tax, or that made filing trivial, threatens the upsell ladder from “free” editions to Premier and Self-Employed tiers.

That incentive shows up clearly in lobbying — not always under the banner “save the income tax,” but under fights that protect paid filing:

Direct File and Free File

For years, commercial preparers shaped the old IRS Free File partnership and later poured money into fighting IRS Direct File, the government-run free e-file tool. OpenSecrets and other trackers have documented tens of millions in federal lobbying by Intuit and H&R Block over two decades, with record spending in the mid-2020s as Direct File expanded — and was later shut down.

Intuit has described government filing tools as competition in public comments and disclosures. Critics call that what it looks like: an industry defending a captive seasonal market.

Complexity is a product feature

Every new credit, phaseout, and information-reporting form is a headache for taxpayers — and a reason to buy software or walk into a storefront. An industry that has spent heavily to keep the IRS out of “free and simple” filing is not going to cheer a president who wants to make April irrelevant.

Would Intuit lobbyists literally write the memo titled “Please don’t repeal the income tax”? They don’t need to. Their day-to-day asks — kill Direct File, limit IRS modernization, keep prep in the private market — are downstream of the same goal: preserve a world where filing is a commercial product. A Congress that listens to that lobby on free filing is the same Congress that hears from them when radical tax restructuring shows up in draft bills.

Follow the incentives, not the slogans

Put the pieces together:

Actor	Incentive
White House (rhetoric)	Sell tariffs as tax relief; claim income tax could fade
Budget hawks / scorekeepers	Demand a real pay-for; tariffs don’t close the gap
Tax software companies	Keep annual filing paid, private, and complicated
Average filer	Want lower taxes and less paperwork

So when people ask, “Will Congress vote to end the income tax because Trump wants it?” the candid answer is: almost certainly not anytime soon. The fiscal math fails first. Party coalitions fracture second. And when any proposal threatens the filing industry’s revenue — whether that’s a free IRS app or a fantasy of no 1040 at all — Intuit and peers have already shown they will spend millions to shape the outcome.

Ending the income tax would be an extinction-level event for TurboTax season. Expect the lobby that crushed competition from Direct File to treat full repeal as an existential threat, too — even if their public talking points stay wrapped in “taxpayer choice” and “private innovation.”

What filers should do now

Don’t rearrange your finances around a slogan. Until Congress passes and the president signs a law:

1. Keep withholding and estimated payments on track.
2. Watch real legislation (rate cuts, credit changes, deduction fights) — not just speeches.
3. Use our tax changes hub and filing guides for rules that actually apply this year.
4. Compare software on features and price — knowing the industry’s lobbying history is part of being an informed consumer. See our software comparison.

Bottom line

Trump can keep saying tariffs might replace the income tax. Congress has to vote for it — and the combination of impossible revenue math and a tax-prep lobby that monetizes Form 1040 makes a full repeal one of the least likely “big tax ideas” to become law.

The same companies that fought free government filing have every reason to fight a world with no income tax to file. That doesn’t mean lobbyists alone run the tax code. It does mean that when the income tax’s future is debated, Intuit’s interests and Congress’s path of least resistance often point the same direction: keep the April ritual alive.
