The U.S. tax code is constantly evolving, and our current iteration is no exception. The Tax Cuts and Jobs Act (TCJA), which was enacted in 2017, brought significant changes to the United States tax code. However, many of its provisions are set to expire at the end of 2025, a “sunset” which is going to significantly affect both individual and business taxpayers across the nation.

There is always a possibility that new legislation will get enacted between now and the date set for the TCJA sunset. However, if it goes through, this will result in higher tax rates for many individuals and families on their income taxes, a marked reduction in tax deduction and notable changes to credits starting in the 2026 tax year. It is, therefore, essential that you understand what changes are coming down the pipeline so you can effectively plan your financial and tax strategies.

As we approach 2025, our expert tax consultants recommend that you consider how you can best maximize your tax savings before the current provisions expire and get ahead of the impact that will be felt in the latter years. Taking proactive steps now can help you mitigate the impact of the sunset on your overall financial well-being in the years ahead.

We have created this article as a resource for you to understand what the TCJA sunset means for you as an individual or a business owner, what changes are expected, and, most importantly, provide strategies to help you navigate the upcoming tax landscape in the most effective (and financially sound) manner.

Overview of the Tax Cuts and Jobs Act

The Tax Cuts and Jobs Act (TCJA) of 2017 brought sweeping changes to the U.S. tax code. It significantly altered tax rates, deductions, and credits for both individuals and businesses. The law aimed to simplify the tax system and stimulate economic growth.

Key Provisions and Objectives

The TCJA reduced individual tax rates across most brackets. It nearly doubled the standard deduction to $12,000 for single filers and $24,000 for married couples filing jointly. The law eliminated personal exemptions but expanded the Child Tax Credit.

For businesses, the TCJA lowered the corporate tax rate from 35% to 21%. It introduced a new 20% deduction for qualified business income for pass-through entities. The act also allowed full expensing of certain capital investments.

The law capped state and local tax deductions at $10,000. It limited mortgage interest deductions and eliminated several itemized deductions. These changes were designed to simplify tax filing for many Americans.

Impact on Individual Taxpayers

You likely saw changes to your tax liability under the TCJA. The increased standard deduction meant fewer taxpayers itemized deductions. This simplified tax filing for many.

Your tax brackets shifted, with most rates lowering slightly. For example, the top rate dropped from 39.6% to 37%. The law also expanded the Child Tax Credit from $1,000 to $2,000 per child.

The Alternative Minimum Tax (AMT) exemption increased, reducing the number of taxpayers subject to it. However, the $10,000 cap on state and local tax deductions impacted some high-tax state residents.

Effect on Businesses

Your business may have benefited from the TCJA’s reduced corporate tax rate. The new 21% flat rate replaced the previous graduated system topping out at 35%.

If you own a pass-through entity, you might qualify for the 20% Qualified Business Income deduction. This applies to sole proprietorships, partnerships, and S corporations.

The act allowed 100% bonus depreciation for qualified property. This lets you deduct the full cost of eligible assets in the year they’re placed in service. The law also expanded Section 179 expensing limits.

International tax rules changed significantly. The TCJA moved towards a territorial system and introduced new provisions like Global Intangible Low-Taxed Income (GILTI) and Foreign-Derived Intangible Income (FDII).

Understanding Sunset Provisions

Sunset provisions play a crucial role in tax legislation, including the Tax Cuts and Jobs Act (TCJA). These temporary measures have significant implications for taxpayers and financial planning.

Definition and Purpose

Sunset provisions are clauses in legislation that specify when certain laws or parts of laws will expire. In tax law, they set an end date for specific tax rules or rates. The purpose is to allow for temporary changes without permanently altering the tax code.

You’ll find sunset provisions useful for testing new policies or providing temporary relief. They give lawmakers flexibility to address short-term economic needs or budget constraints. When a provision sunsets, the law typically reverts to its previous state unless Congress takes action to extend or modify it.

Specific Sunsets under TCJA

The TCJA introduced numerous tax changes set to expire after 2025, but some of which will likely be addressed by Congress prior to expiration. You should be aware of several key sunsets:

• Individual tax rates will return to pre-TCJA levels, with the top rate increasing from 37% to 39.6%.
• The standard deduction will decrease, potentially affecting your itemized deductions strategy.
• Personal exemptions will be reinstated.
• The child tax credit will revert to $1,000 per child from $2,000.
• The estate tax exemption will be reduced, impacting estate planning for high-net-worth individuals.

These sunsets will significantly change your tax situation. Planning ahead can help you navigate these changes effectively.

Changes in Deductions and Exemptions

The Tax Cuts and Jobs Act (TCJA) introduced significant changes to deductions and exemptions, affecting how taxpayers calculate their taxable income. These modifications impact state and local tax deductions, mortgage interest deductions, personal exemptions, and standard deductions.

Limits on State and Local Tax

The TCJA imposed a $10,000 cap on state and local tax (SALT) deductions. This limit applies to the combined total of property taxes and either income or sales taxes.

For high-tax states, this cap significantly reduced the tax benefit of SALT deductions. Previously, there was no limit on these deductions.

The SALT cap particularly affects homeowners in states with high property taxes. It may influence decisions about home purchases or relocations.

When the TCJA sunsets, the SALT deduction limit will be removed. You’ll be able to deduct the full amount of your state and local taxes again.

Adjustments to Mortgage Interest Deduction

The TCJA modified the mortgage interest deduction, reducing the amount of mortgage debt eligible for the deduction from $1 million to $750,000 for new mortgages.

This change primarily impacts high-value homes and areas with expensive real estate markets. The reduced limit applies to the combined amount of loans used to buy, build, or substantially improve your main home and second home.

Interest on home equity loans is now only deductible if the loan is used to buy, build, or substantially improve the home that secures the loan.

After the TCJA sunset, the mortgage interest deduction limit will revert to $1 million, potentially benefiting those with larger mortgages.

Elimination of Personal Exemptions

The TCJA temporarily suspended personal exemptions. Prior to 2018, you could claim a personal exemption for yourself, your spouse, and each dependent, reducing your taxable income.

In 2017, the personal exemption was $4,050 per person. For a family of four, this could have reduced taxable income by $16,200.

The elimination of personal exemptions was partially offset by the increased standard deduction and expanded Child Tax Credit.

When the TCJA sunsets in 2026, personal exemptions will return. The amount is expected to be around $4,700 per person, adjusted for inflation.

Increased Standard Deduction

To compensate for the elimination of personal exemptions, the TCJA nearly doubled the standard deduction. This change simplified tax filing for many taxpayers.

For 2024, the standard deduction amounts are:

• $14,600 for single filers
• $29,200 for married couples filing jointly
• $21,900 for heads of household

The higher standard deduction means fewer taxpayers itemize deductions. This simplifies tax preparation but may reduce the tax benefits of charitable giving and mortgage interest for some.

Following the sunset, the standard deduction will decrease. You’ll need to compare your potential itemized deductions with the new, lower standard deduction to determine which method results in a lower tax liability.

Implications for Estate and Gift Tax Planning

The Tax Cuts and Jobs Act (TCJA) sunset will significantly impact estate and gift tax planning. You need to understand the changes to lifetime exemptions, annual gift tax exemption, and potential strategies to optimize your wealth transfer.

Lifetime Exemption Adjustments

The estate and gift tax exemption is set to decrease substantially after 2025. Currently, you can transfer up to $12.92 million ($25.84 million for married couples) tax-free during your lifetime or at death. This amount will likely revert to approximately $7 million per individual in 2026.

You should consider using your increased exemption before it expires. Gifting assets now can help you lock in the higher exemption amount. This strategy is particularly effective if you expect your estate to exceed the lower exemption threshold post-2025.

Remember, the IRS has confirmed that gifts made under the higher exemption will not be clawed back if the exemption decreases.

Gift Tax Annual Exclusion

The gift tax annual exclusion allows you to give away a certain amount per recipient each year without using your lifetime exemption. This amount is adjusted for inflation and is currently $17,000 per recipient for 2023.

While the TCJA sunset doesn’t directly affect this exclusion, it becomes more important as a planning tool when the lifetime exemption decreases. You can use this exclusion to gradually transfer wealth over time without incurring gift tax or using your lifetime exemption.

Consider establishing a systematic gifting program to take full advantage of this exclusion each year. This can be an effective way to reduce your taxable estate over time.

Strategies for High-Net-Worth Individuals

If you’re a high-net-worth individual, you should explore advanced estate planning techniques to maximize the current higher exemption. Some strategies to consider include:

1. Grantor Retained Annuity Trusts (GRATs)
2. Installment sales to Intentionally Defective Grantor Trusts (IDGTs)
3. Spousal Lifetime Access Trusts (SLATs)

These techniques can help you transfer wealth while minimizing gift and estate taxes. It’s crucial to work with an experienced estate planning attorney to implement these strategies correctly.

You should also review and update your existing estate plan to ensure it remains effective under the new tax regime. Consider flexible planning techniques that allow for adjustments as tax laws change.

Tax Planning for Individuals and Families

The TCJA sunset will affect various aspects of personal finance. You should consider adjusting your tax strategy to account for upcoming changes in income tax rates, deductions, and exemptions.

Impact on Different Income Levels

Your income level will determine how the TCJA sunset affects you. Tax rates will revert to pre-2018 levels, potentially increasing your tax burden. If you’re in a higher bracket, you may face a more significant impact.

For lower-income earners, the change might be less noticeable. However, you should still prepare for potential increases. The standard deduction, nearly doubled by the TCJA, will decrease. This reduction could affect your taxable income.

Consider accelerating income into 2025 if possible. This strategy may help you take advantage of lower rates before they expire. Consult a tax professional to determine if this approach suits your situation.

Retirement Contributions and Planning

Your retirement planning may need adjustment due to the TCJA sunset. Consider increasing your contributions to tax-advantaged accounts. This strategy can help lower your taxable income.

Roth IRA conversions might become more attractive. With potentially higher tax rates post-sunset, converting now could save you money in the long run. Evaluate your current and expected future tax brackets to decide if this makes sense for you.

Review your investment strategy. Capital gains taxes may increase for some individuals. You might want to realize gains before the sunset if you’re in an affected bracket.

Charitable Giving and Tax Benefits

The TCJA sunset will impact charitable giving strategies. The annual deduction limit for cash contributions to public charities will decrease from 60% to 50% of AGI. Plan your donations accordingly.

Consider bunching charitable contributions. This approach involves making larger donations in alternating years to exceed the standard deduction. It can help you maximize your tax benefits.

Donor-advised funds might become more attractive. These allow you to make a large contribution in one year and distribute the funds over time. This strategy can help you take advantage of current tax benefits while supporting causes over several years.

Understanding Business Income and QBI Deduction

The Qualified Business Income (QBI) deduction offers significant tax benefits for small-business owners. This provision allows eligible taxpayers to deduct up to 20% of their business income from certain pass-through entities.

Eligibility for Small-Business Owners

You may qualify for the QBI deduction if you own a pass-through business such as a sole proprietorship, partnership, S corporation, or limited liability company. The deduction applies to income from these entities, but not from C corporations or income earned as an employee.

To be eligible, your taxable income must fall below certain thresholds. For 2024, these limits are $182,100 for single filers and $364,200 for joint filers. Above these limits, the deduction may be reduced or eliminated depending on your business type and income level.

Some service businesses, like law firms and medical practices, face additional restrictions on the QBI deduction at higher income levels.

Calculating the Qualified Business Income Deduction

Your QBI deduction is generally 20% of your qualified business income. This includes net income from your business operations, but excludes capital gains, dividends, and interest income not related to the business.

To calculate your deduction:

1. Determine your total QBI from all qualifying businesses
2. Calculate 20% of that amount
3. Compare this to 20% of your taxable income minus net capital gains

Your deduction is the lesser of these two amounts. For high-income taxpayers, additional limitations may apply based on W-2 wages paid and the unadjusted basis of certain property used in the business.

It’s important to note that the QBI deduction is set to expire after 2025 unless Congress takes action to extend it.

Preparing for the TCJA Sunset

The Tax Cuts and Jobs Act (TCJA) is set to expire at the end of 2025. This impending change necessitates proactive planning to navigate potential shifts in the tax landscape. Understanding your current financial position, anticipating tax law changes, and seeking expert advice are crucial steps in preparing for the TCJA sunset.

Reviewing Current Financial Position

Start by assessing your current financial situation. Take stock of your income sources, investments, and deductions. Evaluate your standard deduction and compare it to your itemized deductions.

Consider the following:

• Your current tax bracket and potential changes
• Charitable giving strategies
• Retirement account contributions
• Business income and deductions

Review your estate plan, especially if you have a high net worth. The lifetime estate and gift tax exemption may decrease after the TCJA sunset.

Considering Potential Tax Law Changes

Anticipate how the expiration of TCJA provisions might affect you. Tax rates are likely to increase for many taxpayers. The standard deduction may decrease, while personal exemptions could return.

Key areas to focus on:

• Income tax brackets and rates
• Deductions for state and local taxes (SALT)
• Child tax credit changes
• Alternative Minimum Tax (AMT) exemptions

Be aware that Congress may act to extend some TCJA provisions or introduce new tax legislation. Stay informed about potential updates to tax laws, including recent changes like the SECURE 2.0 Act.

Engaging Professional Tax Advice

Seek guidance from a qualified tax professional or financial advisor. They can help you develop strategies tailored to your specific situation and goals. A professional can assist with:

• Tax projection scenarios for 2026 and beyond
• Identifying opportunities for tax-efficient moves before it happens
• Evaluating the impact of potential tax law changes on your investment portfolio
• Developing a flexible plan that can adapt to future legislative changes

Consider timing your income and deductions strategically. Your advisor can help you decide whether to accelerate income or defer deductions based on projected tax rates.
