Several of the most familiar write-offs in the federal code are being reshaped or erased as 2026 rules lock into place. The Internal Revenue Service is implementing a package of changes tied to the Tax Cuts and Jobs Act and the newer One Big Beautiful Bill framework, and some of the quietest shifts will hit the deductions and credits households have long counted on. I want to walk through the biggest breaks that are shrinking or disappearing, and how the new structure will redirect tax relief toward different groups of filers.
The end of personal exemptions and the rise of bigger standard deductions
The most fundamental break that taxpayers are losing is the traditional personal exemption, which for decades let households subtract a set amount for each member of the family before calculating tax. Earlier changes under the Tax Cuts and Jobs Act, or TCJA, suspended that benefit and replaced it with a much larger standard deduction, and the new law now makes that structure permanent. Analysts looking at federal rules for 2026 describe this as one of the clearest examples of how the reform impacted taxpayers and business owners, with Key Takeaways The and Many of the individual provisions either extended or locked in for good.
IRS guidance on 2026 inflation updates confirms that Personal exemptions remain at zero while the highest tax bracket (37%) and other thresholds are adjusted upward. In practice, that means families who once stacked a standard deduction on top of multiple exemptions now rely almost entirely on the larger single deduction. Wealth planners note that the new legislative package built on the original Tax Cuts and, and Passed rules that extend this approach for further generations, so there is little prospect of personal exemptions returning under current law.
Itemized deductions squeezed: SALT, moving costs and more
Another category of disappearing relief is the set of itemized deductions that used to reward specific expenses, from state taxes to job-related moves. Analysts tracking the One Big Beautiful Bill Act, often shortened to OBBBA, report that it made permanent the TCJA limitations on certain itemized deductions, including a tighter cap on deductible mortgage interest and other write-offs. A separate review of federal income tax breaks notes that Here is a look at tax breaks that the new law effectively repealed, including Personal exemptions and How the 2017 law changed this tax break for moving expenses, which are now gone for most workers.
Homeowners in high-tax states will feel the pressure most acutely through the state and local tax cap. Wealth advisors explain that the State and local tax (SALT) limitation remains in place for 2026, with separate changes only beginning in tax year 2030. At the same time, a detailed breakdown of popular tax breaks points out that moving expense deductions are now largely confined to certain military moves, and that tax breaks for moving expenses available before the TCJA have been eliminated for most filers under the new law. A separate analysis of three disappearing breaks underscores that Just when you thought you knew your federal income taxes, the moving expense deduction and related benefits that existed before the TCJA are no longer available under the current framework, cementing the shift away from niche itemized write-offs.
Child and family benefits reshuffled under the Working Families Tax Cut
Family-focused tax relief is not vanishing, but it is being restructured in ways that change who benefits most. The One Big Beautiful Bill, also known as the Working Families Tax, implements a series of new and increased tax breaks that concentrate support on households with children and low to moderate wages. Under this structure, the Child tax credit, often shortened to Child and CTC, got a boost, while some overlapping benefits like personal exemptions and miscellaneous dependent credits were effectively replaced. Financial planners describe this as a trade, where families receive more generous per-child support but lose some of the flexibility that came from stacking multiple smaller breaks.
Guides to 2025 and 2026 filing seasons emphasize that the CTC remains one of the most valuable credits on the return, but its design now interacts closely with income thresholds and earned income rules. At the same time, the IRS has adjusted standard deduction amounts and bracket thresholds so that more low-income families owe no federal income tax at all, while middle earners see their relief concentrated in a few large provisions rather than a long list of smaller ones. A video overview of The One Big Beautiful Bill notes that the Child Tax Credit got a boost as part of a broader Working Families Tax Cut package, which is consistent with the broader shift away from exemptions and toward targeted credits for children and caregiving.
Retirement and workplace perks: catch-up breaks and 401(k) changes
Retirement savers are also seeing a quiet reordering of incentives, especially higher earners who relied on special catch-up rules. A recent IRS update on contribution limits explains that the IRS raises retirement limits for 2026 amid a push to help savers invest, but that some catch-up contribution changes impact high-earners, who lose a key tax break under the new rule. In 2026, workers can contribute more overall, yet certain older, higher income employees must route catch-up dollars into Roth-style accounts, which removes the immediate deduction and shifts the benefit to future tax-free withdrawals.
Corporate plan sponsors are adjusting to these rules at the same time that broader 401(k) updates take effect. A summary of Upcoming tax law changes highlights IRS adjustments, 401(k) updates, OBBBA changes, and more, and includes Highlights that the standard deduction increases while some specialized breaks fade. Consumer-facing tax guides remind savers that they can still deduct contributions to their own 401 plans, with one overview of popular deductions explicitly noting that workers can fund their own 401(k)s and in some cases traditional IRAs. The net effect is that retirement tax relief is tilting toward broad participation and away from extra perks for the highest earners.
Small-business and tip income breaks narrowed by new caps
Self-employed workers and small-business owners are facing their own set of disappearing or reshaped breaks as 2026 rules settle in. Detailed tax tips on the One Big Beautiful Bill explain that Changes that might affect the most common 2025 tax returns include no tax on tips and a deduction of up to $25,000 per taxpayer with respect to certain expenses, and that these Changes carry into 2026 and on. A related explanation of One Big Beautiful Bill Tax Law Changes for your 2026 return notes that the qualified business income deduction remains available at 20% for many pass-through owners, but that phaseouts and income thresholds limit access for higher earners, effectively trimming a popular break for some professionals.
At the same time, the broader One Big Beautiful Bill Act Tax Cuts The One Big Beautiful Bill Act preserves and expands many of the tax breaks that were due to expire at the end of this year, while allowing others to lapse. A breakdown of One Big Beautiful The One Big Beautiful Bill Act shows that some expiring incentives for equipment purchases and certain business credits were extended, but that other temporary provisions were allowed to sunset. For gig workers and service employees, the promise of no tax on tips is a significant shift, yet it comes alongside the loss of miscellaneous itemized deductions for unreimbursed job expenses that many used to claim. The IRS has also published a dedicated overview of One Big Beautiful provisions, underscoring how the law trades some long-standing write-offs for new targeted relief.
