The core proposal: lower income tax rates and a simpler bracket structure
Trump's tax plan centers on reducing the number of federal income tax brackets and lowering the rates within them. The proposal collapses the current seven tax brackets into three: 12%, 25%, and 33%. This differs from the current system, which ranges from 10% to 37% across seven brackets depending on your income level.
The exact income thresholds for each bracket have not been finalized in all versions of the plan. Different proposals released at different times have used different cutoff points. The general intent is to move most middle-income earners into the 25% bracket and higher earners into the 33% bracket, with the lowest earners in the 12% bracket.
Whether you would pay less tax under this structure depends on your current bracket and income. Someone in the current 22% bracket might pay less at 25%, while someone in the current 12% bracket would pay more. The actual dollar impact requires knowing your specific income and filing status.
Key Takeaways
- The plan proposes three income tax brackets (12%, 25%, 33%) instead of the current seven, though the income thresholds for each bracket vary across different versions of the proposal.
- Corporate tax rates would drop from 21% to 15%, which affects business owners and shareholders but not wage earners directly.
- The standard deduction would increase, meaning more people would take a flat deduction rather than itemizing deductions.
- Capital gains and dividend rates would remain tied to income tax brackets, so lower income tax rates would also lower investment income taxes for most people.
- The plan does not specify how it would offset the revenue loss from lower rates, which is a key point of debate among economists and policymakers.
Corporate tax rate and business structure changes
The plan proposes lowering the corporate income tax rate from 21% to 15%. This applies to C corporations—the standard business structure for large companies. Pass-through entities like S corporations, partnerships, and sole proprietorships would also see changes, though the exact treatment varies across different versions of the proposal.
A lower corporate rate means businesses keep more of their profits. This can affect you indirectly if you own company stock or receive dividends, since companies with higher profits may pay higher dividends or see stock prices rise. However, it does not directly change the income tax you pay on your wages.
The plan also proposes allowing businesses to deduct the full cost of equipment and machinery in the year they purchase it, rather than spreading the deduction over several years. This is called "full expensing" and is intended to encourage business investment.
Changes to deductions and the standard deduction
The plan increases the standard deduction, which is the flat amount you can deduct from your income before calculating taxes. A higher standard deduction means fewer people would benefit from itemizing deductions (listing out mortgage interest, charitable donations, state taxes, and other specific expenses).
Most taxpayers already use the standard deduction rather than itemizing. Raising it further would simplify tax filing for those people but could reduce the tax benefit for homeowners with large mortgages or people who make substantial charitable donations, since they would no longer itemize.
The plan does not propose eliminating specific deductions like the mortgage interest deduction or charitable deduction. It simply makes the standard deduction large enough that most people would not need to itemize to use them.
Capital gains and investment income treatment
Under the plan, capital gains and may have access to dividends would be taxed at the same rates as ordinary income—12%, 25%, or 33%—rather than at separate preferential rates. Currently, long-term capital gains are taxed at 0%, 15%, or 20% depending on your income level, which is lower than ordinary income rates.
This change would increase taxes on investment income for most people. Someone who sells stock at a profit or receives dividend income would pay the same rate as someone earning wages at the same income level. The exception is that the lowest earners might still see a 0% rate on capital gains if the plan preserves that feature, though this is not specified in all versions.
This affects people who have investment accounts, retirement accounts with taxable gains, or who sell real estate or other assets at a profit. It does not affect people whose income comes entirely from wages.
What the plan does not specify
The plan does not detail how it would handle the Alternative Minimum Tax (AMT), a separate tax calculation that high-income earners must check to ensure they pay at least a minimum amount. It also does not specify whether the estate tax—the tax on inheritances over a certain threshold—would change.
The plan does not explain how it would offset the revenue loss from lower tax rates. Lowering rates without cutting spending or broadening the tax base increases the federal deficit. Different versions have suggested different approaches: some propose cutting specific deductions, others propose tariffs on imports as revenue, and others do not address the offset at all.
Tax brackets, deductions, and rates can change based on inflation each year. The plan does not specify whether these new brackets and rates would be indexed to inflation or remain fixed.
How this compares to the current tax code
The current federal income tax has seven brackets ranging from 10% to 37%. The standard deduction is $13,850 for single filers and $27,700 for married couples filing jointly (2023 amounts; these adjust annually). Capital gains are taxed at preferential rates of 0%, 15%, or 20%.
Trump's plan simplifies the bracket structure but raises rates on investment income. It raises the standard deduction, which simplifies filing for most people but reduces itemized deductions. The corporate rate cut is more straightforward: it lowers the rate from 21% to 15%.
Whether the overall effect is a tax cut or tax increase for you depends on your income level, whether you have investment income, whether you itemize deductions, and whether you own a business. A wage earner in the middle-income range might see a small cut; a high-income investor might see a larger increase due to capital gains changes.
Frequently Asked Questions
Would I pay less in taxes under this plan?
It depends on your income, filing status, and whether you have investment income. Someone earning $60,000 as a wage earner might see a small decrease. Someone earning $200,000 with significant capital gains would likely see an increase because capital gains would be taxed at higher rates. You would need to calculate your tax under both the current system and the proposed system to know for certain.
What happens to Social Security and Medicare taxes?
The plan does not propose changes to Social Security or Medicare payroll taxes, which are separate from income tax. Those taxes remain at their current rates: 6.2% for Social Security and 1.45% for Medicare, with employers matching those amounts.
Would this plan actually become law?
Tax changes require approval from Congress. A proposal is not law until both the House and Senate pass it and the President signs it. Different versions of the plan have circulated, and Congress may modify or reject parts of it. This guide describes the proposal as stated, not whether it will be enacted.
How would this affect my retirement accounts?
The plan does not specify changes to 401(k)s, IRAs, or other retirement accounts. If you have taxable investments outside retirement accounts, the higher capital gains rates would apply when you sell those investments at a profit. Withdrawals from traditional retirement accounts would still be taxed as ordinary income at the new rates.
Does the plan address state and local taxes?
The plan does not propose changes to the state and local tax (SALT) deduction, which currently caps at $10,000 per year. It also does not address state income taxes, which are separate from federal taxes and set by each state.
