2025 Tax Laws: What Small Business Owners Need to Know

Staying on top of tax law changes might not be the most exciting part of running a business, but it’s one of the smartest ways to protect your hard work and set yourself up for success. The 2025 updates bring new opportunities to save and new rules to navigate, but with a little preparation, you can make them work in your favor. We’ve broken down the key changes and provided actionable steps to help you tackle tax season with confidence and keep your focus on growing your business.

1. Changes to Standard Deduction and Tax Rates

The IRS has adjusted tax brackets and standard deductions to account for inflation. Here’s what small business owners should note:

• Standard Deduction:
  • Single filers: $15,000 (up from $14,600).
  • Married filing jointly: $30,000 (up from $29).
• Tax Brackets: Marginal rates have been slightly adjusted. Review the new brackets to plan your estimated tax payments for 2025.

2. Expanded Home Office Deduction Criteria

The IRS has clarified rules for the home office deduction. If you use a portion of your home exclusively for business, you may now:

• Deduct a portion of expenses like internet, utilities, and mortgage interest more easily with simplified criteria.
• Use a revised formula for shared spaces used primarily for business.

3. New Energy Efficiency Incentives

Small businesses that invest in energy-efficient upgrades may qualify for expanded tax credits under the Inflation Reduction Act’s extended provisions:

• Commercial Building Energy Credit: Increased incentives for installing solar panels, energy-efficient HVAC systems, and LED lighting.
• Electric Vehicle (EV) Tax Credits: Higher credits for purchasing or leasing electric vehicles for business purposes.

4. Section 179 and Bonus Depreciation Updates

Changes to depreciation rules could affect how you deduct equipment and property expenses:

• Section 179 Deduction: The limit has increased to $1.2 million, allowing more immediate expense deductions for equipment purchases.
• Bonus Depreciation: Phased down to 60% in 2025 (from 80% in 2024), so plan large purchases accordingly.

5. Health Insurance Tax Credit Adjustments

The Small Business Health Care Tax Credit remains available but with updated eligibility requirements:

• For businesses with fewer than 25 employees and average wages below $66,600.
• Employers must provide coverage through a Small Business Health Options Program (SHOP) Marketplace to qualify.
• Employers must pay at least 50% of the cost of employee-only — not family or dependent — health care coverage for each employee.

6. State-Specific Tax Considerations

Several states have enacted new tax regulations that could affect small businesses:

• California: Higher minimum wage thresholds may alter payroll tax contributions.
• Texas: Businesses making under $2.47 million no longer need to file a No Tax Due Report; this change was first implemented in 2024. 
• New York: Expanded small business tax relief programs.

Check your state’s tax authority for details.

7. Digital Transactions and Payment Platforms

The IRS continues to enforce new reporting requirements for digital payments via platforms like PayPal, Venmo, and Zelle:

• Transactions over $600 must now be reported via Form 1099-K.
• Ensure accurate bookkeeping for all digital payment transactions.

8. Retirement Plan Contribution Limits

Contribution limits for small business retirement plans have increased:

• SEP IRAs: Maximum contribution is now $70,000 (up from $69,000).
• Solo 401(k)s: Employee deferral limit is $23,500 (up from $23,000), with a $7,500 catch-up contribution for those aged 50+.

9. Audit Risk for Small Businesses

The IRS has increased audits targeting high-income earners and small businesses. Small business owners need to:

• Keep detailed records of expenses, payroll, and income.
• Ensure proper categorization of independent contractors versus employees.

10. Filing Deadlines and Tips

• Quarterly Estimated Taxes: Due dates remain April 15, June 15, September 15, and January 15.
• 2025 Tax Filing Deadline: April 15, 2026. Consider early preparation to avoid last-minute stress.
