Key Tax Changes for 2025: What Small Business Owners Need to Know
Some big tax updates are coming in 2025 that can help small and mid-sized businesses save money—especially when it comes to buying equipment, investing in growth, and planning for taxes. Here’s what you need to know:
1. Section 179 Expensing: Bigger Deductions for Equipment Purchases
- Starting in 2025, you can now deduct up to $2.5 million in equipment or software purchases right away instead of spreading the cost out over several years.
- This deduction starts to phase out if you buy more than $4 million worth of qualifying items in a year.
- It applies to new or used equipment—as long as it is new to your business and used for business more than 50% of the time.
- Why it matters: If you’re thinking about upgrading your tools, software, or vehicles, doing it in 2025 could give you a major tax break.
2. Bonus Depreciation: Full Deduction is Back—Permanently
- As of January 19, 2025, you can once again deduct 100% of the cost of qualifying assets—like machinery, computers, and certain buildings—in the year you buy and start using them.
- This applies to property placed in service after that date and also includes newly built manufacturing property (if construction starts before 2031).
- Why it matters: If you’re expanding, modernizing, or even considering buying another business, these deductions can help offset the cost immediately.
3. Qualified Business Income (QBI) Deduction: Made Permanent
- The 20% tax deduction for qualified business income (QBI) is now permanent for sole proprietors, partnerships, S-corporations, and LLCs.
- The rules for income limits and how much of your business’s wages and assets count toward this deduction have been updated to be more generous.
- There’s also a new minimum $400 deduction for people with at least $1,000 of “active” business income—even if they wouldn’t normally qualify under the old rules.
- Why it matters: If you run your own business, this can cut your tax bill significantly—especially if you’re in a service-based business like consulting, law, or healthcare.
Other Important Tax Updates for 2025
- R&D Write-Offs: If you spend money on research and development in the U.S., you can now deduct those costs right away (instead of over several years), which is great news for innovative small businesses.
- Business Loan Interest: The way you calculate the interest you can deduct on business loans is changing for the better—making it easier to deduct more of your loan interest starting in 2025.
Bottom Line
These 2025 tax updates are designed to encourage business investment, reduce taxable income, and make things a bit easier for small business owners. Whether you’re buying equipment, expanding your operations, or just trying to lower your tax bill, planning ahead is key.
