Understanding the complex U.S. tax rules and completing your tax return can be daunting enough.
But we can expect new tax stresses to come from Washington in the not-too-distant future.
On December 31, 2025, significant portions of the 2017 federal tax law are scheduled to expire. Once that sun sets, they’ll be back to where they were unless that sweeping tax bill passed in the first year of the Trump administration takes effect.
The core features of the tax law are: what tax rate must be paid, what the basic deduction is, how business income is treated, and the tax exemption limit for high-value items such as inherited property and inherited property. What will the amount be? A federal deduction available for gifts and state and local taxes.
Don’t you think it’s difficult to understand? Now, consider this.
If Congress does nothing, the 2026 tax law will suddenly change from the time the law had changed, effectively creating trillions of dollars in additional debt for taxpayers and an equal amount of revenue for the federal government. I will do it. As if that wasn’t complicated enough, the tax code prior to the 2017 law contained provisions for future inflation adjustments, which led to significant inflation in recent years. These adjustments would have to be applied if the law were to be repealed as planned, making it difficult to estimate the actual numbers for something as important as federal tax brackets.
Keeping the current tax laws in place may seem like a better option. But that’s unlikely, as it would be shockingly expensive.
The Congressional Budget Office estimates that by 2033, “extending all provisions scheduled to expire or have less generosity would cost $3.5 trillion.” useful analysis The study by the Congressional Research Service will partially analyze key components.
sources of uncertainty
This slow-moving tax storm is a direct result of the 2017 tax overhaul.
Taxes have gone down for most, but not all, Americans.
Many people in states with high state and local taxes experienced tax increases because state and local tax deductions were limited to $10,000. It’s the infamous SALT cap. The expiration of this provision will be good news for these regions. However, in most parts of the country, the net effect of the tax review was to reduce burdens.
This expansion has made the tax code enormous and expensive. Congress estimated it would cost the federal government $1.5 trillion in lost tax revenue by 2027. But Congress offset the cost by including a December 31, 2025 deadline. This is a set of postponed tax increases for most of the population until December 31, 2025. In 2026, if all is allowed.
Sometime in 2025, or 2026 if Congress shows an unwillingness to meet critical fiscal deadlines, Congressional leadership and the next president will come up with a solution to this entirely predictable tax dilemma. It’s going to happen.
Politicians, whoever they are, will probably try to avoid raising taxes, and probably also avoiding large increases in the budget deficit. Due in no small part to the 2017 tax cuts, the deficit reached $1.7 trillion in fiscal year 2023.
Eventually some tax agreement will be concluded. But we have no idea what the tax law will be in 2026.
In an ideal world, a tax system like this wouldn’t operate, but we’re stuck with it.
Canceling part of the sunset
Aside from caps on state and local tax cuts, here are highlights of upcoming tax law changes in 2026, provided by the Congressional Research Service. The service is based on Congressional Budget Office estimates of how much it would cost by 2033 if certain portions of 2017 taxes were extended.
-
marginal tax rate. The top tax rate will rise from 37% to 39.6%. Income levels for seven tax brackets will be lowered, increasing tax liability for millions of people. The cost of expanding this part of the tax code: $1.8 trillion.
-
Standard deduction. for 2024 tax year, taxpayers can deduct $14,600 if single and $29,200 if married filing jointly.about 90 percent current taxpayer use This deduction. Before the 2017 law went into effect, the standard deduction was just $6,500 for single taxpayers and $13,000 for joint filers. In 2026, the standard deduction will return to its previous level and will also be adjusted for inflation. Extension cost: $1 trillion.
-
Child tax credit. Eligible individuals will receive $2,000 per child. (A pending bill would raise it until 2025.) In 2026, he would lower it to $1,000. The extension cost is $600 million.
-
Business pass-through deduction. The system allows some self-employed people whose business income is “passed through” to their personal profits to deduct up to 20 percent of their qualifying income. After sunset, your personal income tax rate will be levied. The extension cost is $548 billion.
-
Alternative minimum tax. It was originally intended to force the wealthy to pay at least some income tax. Currently, only 0.1% of households are affected, but in the future it will also apply to: 3.7% after sunset, according to the nonpartisan Tax Policy Center. The extension cost is $1.09 billion.
-
inheritance tax and gift tax. Estates and inter vivos gifts valued at $13.6 million are currently exempt. At daylight, those numbers will drop to an inflation-adjusted $5 million.
Changes to the inheritance tax threshold could pose severe problems for wealthy people. Remember “Throw Mommy”? from the trainTax incentives that unintentionally appeared at the beginning of this century? Carefully timing the death of a wealthy benefactor could save you a lot of money in the coming years. The same goes for gifts. If you have millions of gifts to give, it may be wise to accelerate your giving.
The extension cost is $126.5 billion.
giant shrug
Effective and humane tax planning requires some understanding of what the tax law will look like in the coming years, and that’s exactly what we lack.
“We’re not going to make any big assumptions about what’s going to happen,” said Joel Dixon, head of tax planning research at Vanguard. “The only thing you can count on is greater uncertainty.”
Assuming the current tax system expires on schedule, you could potentially save money by moving income or moving a taxable event, such as the death of your wealthy aunt, from 2026 to 2025. But there’s a good chance Congress will intervene, taxes won’t go up, and the various efforts could become a huge waste of time. (Not only is it morally wrong, it also depends on what you plan on doing in the end, but let me be perfectly clear.)
In fact, even if it seems reasonable that tax rates are not cut again, the budget deficit could widen further. Much will depend on national elections. American politics is not completely rational. That much is not debatable.
So, strengthen yourself by paying your taxes now. An interesting political year awaits us in 2025, and especially in his 2026, with new fiscal challenges.
