Individual tax returns are often viewed as straightforward. If you have a W-2 and a few investment accounts, how complicated can it be?
In this episode of Ask a DHJJ CPA, host Emma Yurchik sits down with Tax Manager Dominick Martin to break down why 1040s are often more nuanced than they appear and how recent legislation, including the One Big Beautiful Bill Act (OBBBA), is reshaping tax planning for individuals.
Whether you’re a W-2 employee, investor, business owner, or managing multiple income streams, here’s what you need to know.
Why “Simple” 1040s Aren’t Always Simple
Many taxpayers assume their return is uncomplicated if they don’t own a business. But complexity often creeps in through:
- Stock option exercises
- Multiple brokerage accounts
- Rental properties
- K-1 investments
- Multi-state income exposure
- Pass-through business income
Even individuals with primarily W-2 income can encounter surprises when capital gains, partnership income, or equity compensation enter the picture.
Common Filing-Time Surprises
Dominick highlighted several issues that frequently catch taxpayers off guard:
1. Capital Gains Without Cash Flow
Taxpayers may sell investments, realize gains, and reinvest proceeds, but still owe tax on the gain. When filing season arrives, they face a large balance due without having set aside cash.
2. Unexpected K-1 Income
Business investments can generate taxable income that’s difficult to estimate when trying to tax plan throughout the year.
3. Underpaid Estimated Taxes
Safe harbor estimated tax payments protect clients from penalties and interest but taxpayers may still have a balance due on their tax filings.
The common theme? Lack of proactive planning.
The OBBBA: What Changed for Individuals?
The One Big Beautiful Bill Act made several impactful changes for individual taxpayers, many of which build on provisions from the Tax Cuts and Jobs Act (TCJA).
Here’s what stands out.
1. Permanent Tax Brackets & Standard Deduction
The lower individual tax brackets introduced under TCJA were set to expire. The OBBBA made them permanent, with inflation adjustments.
- Top individual rate remains at 37% (instead of reverting to 39.6%)
- Elevated standard deduction is now permanent
- Personal exemptions remain eliminated
For many taxpayers, this provides long-term rate clarity.
2. SALT Deduction Expansion
One of the most talked-about changes:
- The SALT deduction cap increased from $10,000 to $40,000 for married filing jointly
- Income phaseouts apply
- Alternative Minimum Tax (AMT) considerations still matter
This change may cause more individuals to itemize again, particularly in high-tax states.
3. No Tax on Tips & Overtime (With Limits)
There has been confusion around the no tax on tips and overtime provisions.
No Tax on Tips
- Deduction of up to $25,000
- Income limitations apply
- Applies to qualifying cash tips
- Does not apply to married filing separate filing status
No Tax on Overtime
- Deduction of up to:
- $12,500 (single)
- $25,000 (married filing jointly)
- Does not apply to married filing separate filing status
- Based on the “premium” portion of overtime pay
- May not be reported on Form W-2 received for the 2025 tax year. Taxpayers may need to look at year-end paystub to calculate the deductible amount.
Accurate reporting and documentation are critical for these deductions.
4. Senior Deduction
A $6,000 deduction for qualifying seniors creates new planning opportunities, including:
- Roth conversions
- Strategic income acceleration
- Retirement distribution timing
5. Auto Loan Interest Deduction
- Up to $10,000 of interest deductible
- Vehicle must be made in the U.S.
- Must be for personal use (not business)
- Purchased in tax years after December 31, 2024.
- Subject to income limitations
- Weight less than 14,000 pounds
6. Expanded 529 Plan Flexibility
- K–12 qualified distributions increased from $10,000 to $20,000 annually
Impacts on High Earners
For high-income taxpayers, the OBBBA creates both stability and new complexity:
- 37% top rate remains permanent
- Itemized deduction limitations begin in 2026
- Estate tax exclusion increased to $15 million per person ($30 million with portability)
Planning for 2026 and beyond will be critical for those in the highest brackets.
Business Owners: Pass-Through & Section 174 Changes
Individual returns are often directly impacted by business activity.
Key provisions include:
- Deductibility of previously capitalized Section 174 R&D costs in 2025
- 100% bonus depreciation for qualifying property placed in service after January 19, 2025.
- Section 179 expansion to $2.5 million
- Permanent 20% Qualified Business Income (QBI) deduction
These changes can significantly increase or decrease personal taxable income depending on the situation.
Introducing “Trump Accounts”
The OBBBA also introduced a new type of child-focused retirement vehicle.
These accounts:
- Apply to children born between 2025–2028
- Allow up to $5,000 annual contributions
- Include a potential $1,000 pilot contribution
- Require a valid Social Security number
Taxpayers need to file Form 4547 to elect participation before the 1st day of the calendar year the child turns 18.
The USPS Postmark Issue: Why Timing Matters
The IRS relies on postmarks to determine timely filing and payment. With mail processing centers further removed from local post offices, delays can impact:
- Estimated payments
- Balance due payments
- Filing deadlines
Best practices:
- Request a hand-applied postmark
- Purchase postage at the counter
- Consider paying electronically
- Use Certified or Registered Mail to obtain a postmarked receipt
Reactive vs. Proactive Taxpayers
Throughout the episode, one theme remained clear:
Tax planning should not only happen in March and April.
Proactive taxpayers:
- Review their tax organizer carefully
- Provide documents early
- Make estimated payments timely
- Communicate life changes (marriage, children, relocation)
- Discuss business growth, restructuring, and multi-state exposure
Reactive taxpayers often experience preventable surprises.
Three Takeaways from This Episode
If you remember nothing else, remember this:
1. The OBBBA Changes Matter
Ask your CPA how the new law affects your 2025 return and future years.
2. Planning Is Year-Round
Quarterly check-ins, withholding adjustments, retirement contributions, and income timing decisions can dramatically change your outcome.
3. Your Business Impacts Your 1040
Pass-through income, Section 174 deductions, and multi-state nexus rules directly affect individual tax filings.
Final Thoughts
Individual tax planning is no longer “set it and forget it.” Between evolving legislation, multiple income streams, and increasing complexity, proactive communication with your CPA is more important than ever.
