The 2025 tax year represents a monumental shift for individuals and business owners alike. As the provisions of the One Big Beautiful Bill Act (OBBBA) and other delayed legislative measures take effect, the financial landscape is undergoing a significant transformation. For our clients here at Christiansen Accounting, staying ahead of these changes isn't just about compliance—it is about finding the strategic advantages hidden within new rate tables, heightened credits, and expanded deductions.
For many filers, the standard deduction is the foundation of their tax return. In 2025, these amounts have been adjusted for inflation to help taxpayers keep more of their earnings. Single filers and those married filing separately will see a standard deduction of $15,750, while heads of household move to $23,625. Married couples filing jointly now have a threshold of $31,500. Looking ahead to 2026, these figures are projected to climb further to $16,100, $24,150, and $32,200, respectively.
A notable addition for the 2025 through 2028 tax years is the Senior Deduction. Taxpayers aged 65 or older can now claim a $6,000 deduction. While this is a below-the-line deduction that does not reduce your Adjusted Gross Income (AGI), it provides meaningful relief. It does phase out for unmarried individuals with a Modified Adjusted Gross Income (MAGI) over $75,000 and married couples over $150,000, reducing by $100 for every $1,000 over those limits. This is reported on the new 1040 Schedule 1-A and is available regardless of whether you itemize or take the standard deduction.
Additionally, those in the creative arts should note that qualified sound recording production expenses incurred after July 4, 2025, are now eligible for bonus depreciation through the end of 2028, offering a significant timing benefit for the music industry.
Managing your retirement accounts requires precise timing, much like a financial dental cleaning—it’s better to be proactive than to deal with the fallout later. The age for Required Minimum Distributions (RMDs) remains at 73. You must calculate your annual withdrawal by dividing the account’s year-end value by the IRS life expectancy factor. While you can postpone your first RMD until April 1 of the year following the year you turn 73, remember that doing so may result in two distributions in a single tax year.
Special rules continue to apply to inherited IRAs. If the original owner passed away after 2019, surviving spouses and certain protected beneficiaries have specific flexibility, but most other beneficiaries must fully distribute the account within 10 years.

One of the most talked-about changes for 2025 is the deduction for qualified cash tips. Workers in customary tip-receiving roles can deduct up to $25,000 of their tips. This benefit phases out for single filers with an AGI over $150,000 and joint filers over $300,000. Like the senior deduction, this is claimed on Schedule 1-A and does not reduce AGI. Employers are expected to track these qualifying tips on W-2 forms under IRS guidance IR-2025-92.
Similarly, a new deduction for qualified overtime pay allows for a deduction of up to $12,500 ($25,000 for joint filers) for pay that exceeds regular rates under the Fair Labor Standards Act. If your regular rate is $20.00 and your overtime rate is $30.00, that $10.00 difference per hour is potentially deductible. For 2025, employers can use reasonable estimation methods, but by 2026, we expect to see this specifically coded as "TT" in Box 12 of the W-2.
If you are in the market for a new car, the New Vehicle Loan Interest Deduction offers a deduction of up to $10,000 on interest for loans secured by U.S.-assembled passenger vehicles weighing under 14,000 pounds. This excludes recreational vehicles and family loans. It phases out between $100,000 and $150,000 for singles and $200,000 to $250,000 for joint filers.
Families will also benefit from an enhanced Adoption Credit, which now includes a refundable portion. For 2025, the credit is $17,280, with $5,000 being refundable. The Child Tax Credit has also seen a boost to $2,200 ($1,700 refundable) for dependents under 17. However, be aware that many environmental tax credits are sunsetting; electric vehicle credits expire after September 30, 2025, and residential solar/energy efficiency credits end on December 31, 2025.

For the entrepreneurs we serve in California, the OBBBA has essentially declared 2025 the "Super Bowl for your books" regarding equipment investment. Section 179 expensing limits have jumped to $2.5 million for 2025, with a phase-out starting at $4 million in total purchases. Additionally, 100% bonus depreciation has been reinstated and made permanent for property placed in service after January 19, 2025. This allows for an immediate write-off of the full cost of qualifying machinery, equipment, and certain improvements, providing a massive boost to cash flow.
Domestic production also gets a nod with the Qualified Production Property Expensing provision. This allows for the expensing of nonresidential real property used in manufacturing or refining, provided construction begins after January 19, 2025. While this is aimed at production, small and medium-sized manufacturing shops should not overlook this opportunity.
Perhaps the most critical update for California residents is the increase in the State and Local Tax (SALT) deduction limit. The OBBBA has raised this cap from $10,000 to $40,000 for 2025 ($40,400 for 2026). For high-income earners, this limit begins to phase back down toward the $10,000 floor once MAGI exceeds $500,000, but the increased ceiling offers substantial relief for many middle-to-high-income households in our state.
Shareholders in C Corporations can benefit from revised Qualified Small Business Stock (QSBS) rules. For stock acquired after July 4, 2025, the exclusion rates for gains are tiered: 50% after three years, 75% after four years, and 100% after five years, with an increased cap of $15 million.
Regarding business interest, the 30% limitation now uses EBITDA (earnings before interest, taxes, depreciation, and amortization) rather than just EBIT, which generally allows for a larger deduction. However, multinational firms should be cautious of new exclusions for foreign income items in the ATI calculation starting in 2026. Small businesses with average gross receipts under $31 million remain exempt from these limitations in 2025.
The utility of Section 529 plans has expanded significantly. Distributions after July 4, 2025, can now cover elementary and secondary school expenses, as well as postsecondary credentialing programs like professional certificates and licenses. This turns the 529 plan into a much more versatile tool for lifelong learning.

Finally, for those worried about 1099-K reporting for casual sales or side hustles, the OBBBA has retroactively repealed the lower $600 threshold. The reporting requirement has returned to the original $20,000 and 200 transactions limit, effective back to 2022, providing much-needed clarity for third-party network transactions.
The 2025 tax environment is complex, but it is filled with opportunities for those who plan ahead. Whether you are navigating business interest limits or looking to maximize your SALT deduction, Christiansen Accounting is here to provide the expertise you need. We invite you to contact us for a consultation to see how these new laws specifically impact your financial future.
For many of our small business clients at Christiansen Accounting, the Qualified Business Income deduction has been a staple of tax planning since its inception. Starting in 2025, a new provision simplifies the benefit for those with smaller, actively managed ventures. If your business generates at least $1,000 in QBI, you are now entitled to a minimum deduction of $400. This is a significant shift because it provides a baseline tax benefit regardless of the standard 20% calculation that usually applies. For a freelancer or a small side-hustle owner here in California, this floor ensures that even modest entrepreneurial efforts are rewarded with a reduction in taxable income. It is important to note that the business must be "actively managed," meaning passive investments that do not meet the material participation standards may not qualify for this specific floor. We recommend reviewing your involvement levels to ensure your business activities meet the IRS criteria for this new minimum benefit.
Planning for the transition out of the workforce often involves a final push to maximize retirement accounts. The OBBBA introduces a powerful new tool for individuals aged 60 through 63. Known as the "Super Catch-Up," this provision allows these taxpayers to contribute significantly more to their employer-sponsored plans. Specifically, you can now contribute the greater of $10,000 or 50% more than the standard catch-up limit to 401(k), 403(b), and 457(b) plans. For 2025, this enhanced limit reaches $11,250 for most major plans, while SIMPLE plan participants see an enhanced limit of $5,250. It is crucial to remember that this enhancement does not currently apply to traditional or Roth IRAs, which maintain their standard catch-up rules. For those in this specific age bracket, this four-year window represents a prime opportunity to bridge any remaining gaps in retirement readiness. Because these limits will be adjusted for inflation starting in 2026, the potential for tax-advantaged growth continues to scale alongside the cost of living.
While the headline-grabbing increase of the SALT limit to $40,000 is welcome news for Californians, the mechanics of the phase-down require careful attention. As income rises, the benefit begins to retract. For taxpayers with a Modified Adjusted Gross Income (MAGI) starting at $500,000, the $40,000 limit reduces gradually. The deduction floor is set at $10,000, which is reached when MAGI hits $600,000. For the 2026 tax year, these thresholds shift slightly due to inflation adjustments, with the phase-down range spanning from $505,000 to $606,333. This means that high-earning households must remain diligent in their year-end planning. At Christiansen Accounting, we often see taxpayers assume they will get the full $40,000 deduction, only to find their effective deduction is much lower due to these income thresholds. Understanding where you sit on this sliding scale is essential for accurately estimating your final tax liability and adjusting your quarterly estimated payments accordingly.
The OBBBA’s push for domestic production includes a temporary but potent incentive for nonresidential real property. To qualify for immediate expensing, the property must be located within the U.S. and its original use must begin with the taxpayer. This is a critical distinction—you cannot purchase a pre-existing manufacturing facility and claim this benefit; the construction or first-use must be yours. Furthermore, the property must be placed in service before 2031, with construction beginning between early 2025 and 2029. The IRS has also placed strict limitations on what parts of a facility qualify. Areas dedicated to administrative services, research, software engineering, or lodging are ineligible. The focus is purely on the physical manufacturing, agricultural production, or chemical refining aspects of the business. For a local family-owned manufacturing plant, this could mean that while the factory floor equipment and the structure housing the machinery are expensable, the front-office suite and the employee parking lot may follow standard, slower depreciation schedules.
With our team of seven employees at Christiansen Accounting, we understand the administrative burden that new legislation places on business owners. The introduction of deductions for tips and overtime requires a two-step implementation process for payroll compliance. For the 2025 tax year, the IRS recognizes that software systems and reporting forms are still being updated. Consequently, employers are permitted to use any "reasonable method" to estimate and report the deductible portion of overtime pay. However, this flexibility is short-lived. By the 2026 tax year, the IRS expects full integration, requiring that qualified overtime be specifically reported in Box 12 of the W-2 using the new code "TT." Similarly, for customary tip-receiving occupations, the IRS release IR-2025-92 provides the framework for what qualifies. Employers must ensure that these tips are accurately reflected on the W-2 so that employees can properly claim the deduction on their 1040 Schedule 1-A. Failing to track these items correctly not only complicates the employee’s tax filing but could also lead to reconciliation issues during an audit.
While the increased Section 179 limits to $2.5 million offer an immediate tax shield, they come with a long-term commitment. One of the most common pitfalls we see is the "recapture" rule. If you expense a vehicle or a piece of machinery in 2025 but your business use of that asset drops to 50% or less in a subsequent year, the IRS requires you to "recapture" the tax benefit. This means you must report the difference between the amount you expensed and the amount of depreciation you would have otherwise been allowed as ordinary income. This can create a surprise tax bill during a year when cash flow might already be tight. When planning large equipment purchases, it is vital to forecast the usage of that asset over its entire recovery period, not just the year of purchase. This is especially true for SUVs and light trucks, which are already subject to specific deduction caps and are often used for both personal and professional tasks.
The evolution of the 529 plan under the OBBBA makes it one of the most versatile investment vehicles for families. Traditionally limited to postsecondary tuition, these funds can now be deployed for elementary and secondary school costs starting in mid-2025. This expansion includes books, fees, and other essential educational expenses. Perhaps more importantly for the modern workforce, 529 funds can now cover postsecondary credentialing. This includes the costs of obtaining professional certificates and licenses, which is a major win for individuals in trades or specialized professional services. By allowing these tax-advantaged funds to pay for licensing exams and certification programs, the law recognizes the value of non-degree professional development. For parents and grandparents in California looking to support the next generation, these changes offer a way to fund a child’s entire educational journey—from kindergarten through professional licensure—within a single, tax-protected account.
The sheer volume of changes introduced by the OBBBA means that the "status quo" for tax filing is no longer sufficient. From the repeal of the lower 1099-K thresholds to the new deductions for seniors and the enhanced SALT limits, nearly every taxpayer will find something that affects their bottom line. Navigating these complexities requires a proactive approach and a clear understanding of how different provisions interact. For instance, claiming the new vehicle interest deduction requires filing the new Schedule 1-A and providing a VIN, a small but necessary administrative step that can easily be missed. At Christiansen Accounting, we remain committed to helping our clients interpret these technical updates and translate them into actionable financial strategies. Whether you are managing a growing business or planning for your own retirement, early preparation is the key to maximizing these new benefits while remaining in full compliance with the evolving tax code.
