Written by TaxPlanIQ Support team | Mar 14, 2025 4:23:38 AM

As a small business owner, staying abreast of tax law changes is crucial to maintaining compliance and optimizing your financial strategy. The 2025 tax year introduces several significant updates that could impact your business’s bottom line. This comprehensive guide will walk you through the most pertinent changes, including adjustments to tax brackets, deductions, and new reporting requirements, ensuring you’re well-prepared for the upcoming tax season.

Revised Tax Brackets Affecting Small Business Owners

Understanding the updated tax brackets is essential for effective financial planning. For the 2025 tax year, the Internal Revenue Service (IRS) has adjusted the income thresholds to account for inflation, which may influence your tax liabilities.

Federal Income Tax Brackets

The federal income tax brackets for 2025 have been modified as follows:

For single filers:

  • 10%: Up to $11,925
  • 12%: $11,926 to $48,475
  • 22%: $48,476 to $103,350
  • 24%: $103,351 to $197,300
  • 32%: $197,301 to $250,525
  • 35%: $250,526 to $626,350
  • 37%: $626,351 and above

For married couples filing jointly:

  • 10%: Up to $23,850
  • 12%: $23,851 to $96,950
  • 22%: $96,951 to $206,700
  • 24%: $206,701 to $394,600
  • 32%: $394,601 to $501,050
  • 35%: $501,051 to $751,600
  • 37%: $751,601 and above

These adjustments reflect a 2.8% increase from the previous year, accounting for inflation.

Impact on Pass-Through Entities

For sole proprietorships, partnerships, S corporations, and certain LLCs—collectively known as pass-through entities—the owners report business income on their personal tax returns. The revised brackets directly influence the amount of tax owed. Strategic planning, such as income deferral or accelerating expenses, can help manage taxable income within favorable brackets.

Changes to Standard Deductions and Business Expenses

Adjustments to standard deductions and allowable business expenses can significantly impact your taxable income.

Increased Standard Deduction

For 2025, the standard deduction amounts have been increased to:

  • Single Filers: $15,000

  • Married Filing Jointly: $30,000

This increase allows small business owners to reduce their taxable income, potentially lowering tax liabilities. Evaluating whether to take the standard deduction or itemize expenses is crucial, as itemizing may yield greater tax benefits depending on your specific circumstances.

Section 179 Expensing and Bonus Depreciation

The Section 179 deduction allows businesses to deduct the full purchase price of qualifying equipment and software purchased or financed during the tax year. For 2025, the deduction limit is set at $1.25 million, with a phase-out threshold of $3.13 million.

Additionally, bonus depreciation permits businesses to deduct a significant percentage of the cost of eligible assets in the first year they are placed in service. However, the bonus depreciation rate is scheduled to phase down in the coming years, making it essential to plan asset acquisitions accordingly.

Qualified Business Income (QBI) Deduction Updates

The Qualified Business Income (QBI) deduction, introduced under the Tax Cuts and Jobs Act, allows eligible pass-through entities to deduct up to 20% of their qualified business income. This deduction is subject to various limitations based on income levels and business types.
For 2025, it’s crucial to note that the QBI deduction is set to expire unless extended by new legislation. The expiration of this deduction could result in higher taxable income for many small business owners. Staying informed about legislative developments and consulting with a tax advisor can help in planning for this potential change.

Beneficial Ownership Information Reporting

In an effort to enhance financial transparency and combat illicit activities, the Corporate Transparency Act (CTA) requires certain businesses to file Beneficial Ownership Information Reports (BOIR) starting in 2025.

Who Must File?

Most corporations, limited liability companies, and other similar entities formed or registered to do business in the U.S. are required to file BOIR, unless specifically exempt (e.g., publicly traded companies, certain regulated entities).

What Information Is Required?

Businesses must report:

  • Full legal name
  • Date of birth
  • Current residential or business address
  • Unique identifying number from an acceptable identification document (e.g., driver’s license or passport)

Filing Deadlines

  • Existing Entities: Must file by March 21, 2025

  • New Entities Formed After January 1, 2025: Must file within 30 days of formation

  • Changes in Information: Must be reported within 30 days of the change

Non-compliance can result in significant penalties. It’s imperative to assess whether your business falls under this requirement and to prepare the necessary information promptly.

Tax Credits and Incentives

Leveraging available tax credits can offset liabilities and support business growth.

Research and Development (R&D) Tax Credit

The R&D tax credit has been expanded to include more industries, particularly benefiting small businesses engaged in technological innovation and product development. Qualifying activities can yield substantial credits against tax owed.

Work Opportunity Tax Credit (WOTC)

Extended through 2025, the WOTC encourages hiring individuals from targeted groups who face significant barriers to employment. This credit can reduce your federal tax liability for each qualifying employee hired.

Employer Retirement Plan Start-Up Credit

Small businesses initiating new retirement plans can benefit from increased start-up credits. For the 2025 tax year:

  • Employers with up to 100 Employees: Can claim a credit of 100% of the start-up costs, up to $5,000 per year

  • Employers with 51 to 100 Employees: Eligible for a 50% credit of start-up costs, up to $5,000 per year

This credit is available for the first three years of the plan, incentivizing businesses to support employee retirement savings.

Tax Planning Strategies for Small Business Owners in 2025

With the latest small business tax updates, proactive tax planning is key to minimizing liabilities and maximizing deductions. Here are some essential strategies to implement in 2025:

1. Maximize Deductions Through Proper Expense Tracking

One of the simplest ways to reduce taxable income is by ensuring all business expenses are accounted for. Many small business owners miss out on deductions due to poor record-keeping.

  • Use accounting software to track expenses in real-time.

  • Deduct eligible business expenses, including office supplies, software subscriptions, and professional services.

  • Keep receipts and documentation for all deductible expenses to avoid IRS scrutiny.

2. Optimize Payroll and Employee Benefits

With the Work Opportunity Tax Credit (WOTC) and expanded retirement plan credits, small business owners can leverage tax savings through payroll planning.

  • Hire strategically: If hiring new employees, check whether they qualify for tax credits under WOTC.

  • Offer retirement benefits: Small businesses implementing a new retirement plan can qualify for up to $5,000 in tax credits over three years.

  • Reassess salary structures: Business owners structured as S corporations can optimize their compensation by balancing salary and distributions to minimize payroll taxes.

3. Consider Pass-Through Entity Taxation Benefits

For sole proprietors, LLCs, and S corporations, pass-through taxation can provide advantages:

  • Qualified Business Income (QBI) Deduction: Pass-through entities may still be eligible for a 20% deduction on business income, though this benefit is set to expire soon.

  • State-Level Pass-Through Entity Taxes (PTETs): Some states offer workarounds for the SALT deduction cap, allowing small businesses to deduct state taxes at the entity level.

4. Leverage Depreciation for Immediate Write-Offs

The IRS allows businesses to write off large purchases through depreciation strategies:

  • Section 179 Expensing: Deduct the full cost of qualifying equipment and software purchases up to $1.25 million.

  • Bonus Depreciation: Though phasing down, businesses can still claim an immediate deduction on eligible asset purchases.

For small business owners investing in new equipment, vehicles, or office improvements, these provisions can significantly reduce taxable income.

5. Manage Estimated Taxes to Avoid Penalties

Many small business owners underpay estimated taxes, leading to penalties.

  • Quarterly tax payments should be made on time to prevent interest charges.

  • Self-employed individuals should review their withholding and estimated tax strategies to avoid underpayment penalties.

  • Monitor cash flow to ensure funds are set aside for tax liabilities.

6. Utilize Tax Credits for Energy-Efficient Upgrades

Businesses investing in energy-efficient upgrades may qualify for tax credits:

  • EV Tax Credits: Purchasing electric vehicles for business use may qualify for federal tax credits.

  • Energy-Efficient Buildings: The 179D deduction provides benefits for businesses upgrading HVAC systems, lighting, and energy-efficient buildings.

Tax professionals should identify available credits and help clients integrate sustainability investments into their tax strategies.
