As we prepare 2025 tax returns, one thing is clear: the tax law changes passed in 2025 did not just adjust rates or thresholds — they changed how several common decisions affect actual tax outcomes.
While the year is over, many of the most important choices for 2025 are still being made during return preparation. These decisions can materially change:
- The amount of tax owed for 2025
- Whether losses or deductions carry forward
- How much flexibility you have in future years
Below are some of the most meaningful opportunities — and tradeoffs — we are actively evaluating as 2025 returns are prepared.
1. Bonus Depreciation vs. Slower Write-Offs: Timing Now Matters More
For businesses that purchased equipment, vehicles, or technology in 2025, depreciation is no longer a simple “expense it all if you can” decision.
Under the updated rules, bonus depreciation is reduced compared to prior years. That means:
- Electing full expensing can still reduce 2025 taxable income
- But doing so may eliminate deductions that would otherwise offset income in future years
Why this matters: If a business has a strong 2025 but expects even higher income in 2026 or 2027, fully expensing assets now may increase total taxes over time. Spreading deductions can preserve future offsets when income is higher.
What this affects on the return:
- Current-year taxable income
- Net operating losses (or lack thereof)
- Future depreciation schedules
2. Section 179 Elections: Helpful — or Harmful — Depending on Income
Section 179 remains available, but its interaction with business income is now more consequential.
The opportunity: Section 179 can still allow large deductions in 2025, even when bonus depreciation is limited.
The risk: If business income is too low — or offset by other losses — a Section 179 election may provide no immediate benefit and reduce deductions that could have been used later.
Why this matters: Section 179 elections are discretionary and permanent. Once made, they generally cannot be reversed.
What this affects on the return:
- Whether deductions actually reduce tax
- Whether losses are trapped or wasted
- Future deduction flexibility
3. Pass-Through Income: The Deduction Is No Longer Assumed
For owners of S corporations, partnerships, and LLCs, the pass-through deduction has become more sensitive to how income is characterized.
The deduction may be fully allowed, partially limited, or eliminated depending on income levels, wages paid, and business activity.
The decision point: How income is reported — wages versus distributions, guaranteed payments versus profit — directly affects whether the deduction applies.
What this affects on the return:
- Effective tax rate
- Value of the pass-through deduction
- Exposure to payroll taxes
4. S Corporation Compensation: Bigger Consequences Than Before
Reasonable compensation has always mattered, but the interaction between payroll taxes, income taxes, and deductions is now tighter.
The opportunity: Properly balanced compensation can preserve deductions, avoid unnecessary payroll tax, and reduce audit risk.
The downside: Overpaying wages can eliminate deductions. Underpaying can trigger penalties and scrutiny.
What this affects on the return:
- Payroll tax expense
- Income tax liability
- Defensibility of the return
5. Capital Gains: Secondary Effects Matter More
For clients who sold real estate, businesses, or investments in 2025, capital gains often affect far more than just the tax on the sale.
Higher income from gains can phase out deductions, trigger surtaxes, and change how other income is taxed.
What this affects on the return:
- Total tax owed
- Availability of other deductions and credits
- Estimated tax requirements going forward
6. Retirement Contributions: Deductible Is Not Always Optimal
Maximizing retirement contributions does not always produce the best tax result under the updated rules.
Higher-income taxpayers may receive limited or no current deduction while still restricting access to funds.
What this affects on the return:
- Adjusted gross income
- Eligibility for other deductions
- Long-term tax efficiency
What This Means for 2025 and Beyond
As 2025 returns are prepared, these decisions directly affect what you owe, what carries forward, and which strategies still make sense.
Just as importantly, they shape how 2026 planning should be approached — earlier, more intentionally, and with fewer assumptions.
Our Perspective
At Wicks Emmett, preparing a tax return under new law is not a data-entry exercise.
It is a process of evaluating options, choosing among tradeoffs, and explaining why a particular approach makes sense — both now and going forward.
