The Key Differences of Section 179 Deduction & Bonus Depreciation
As a business owner, you’re always looking for ways to save money and grow your company. That’s why, in collaboration with our trusted distribution partner, Kelly Spicers, we’re diving into one of the best ways to do that: taking advantage of tax deductions. When you’re ready to buy new equipment or assets, you’ll hear about two powerful options: Section 179 deduction and bonus depreciation.
Both are great for lowering your tax bill, but they work in different ways. Understanding these differences is crucial for selecting the most effective strategy for your business.
Understanding Section 179

Think of Section 179 as a way to get a huge tax break upfront. Instead of writing off a small portion of the equipment’s cost each year for many years, you can deduct the entire purchase price in the very first year you use it. This is a game-changer for small and medium-sized businesses that need immediate relief and want to invest in new tools to grow.
Here’s the quick rundown on Section 179:
- It’s Your Choice: You get to decide whether to take this deduction or not.
- There’s a Cap: There’s a Cap: There’s a limit on how much you can deduct in a year. For 2025, the maximum deduction is $2.5 million.
- Spending Limit: The deduction starts to shrink if your business spends too much on equipment in a year. In 2025, the deduction begins to phase out on a dollar-for-dollar basis if your company spends more than $4 million on qualified assets.
- What Qualifies?: It covers a wide range of things, like machinery, office equipment, software, and even certain vehicles.
Understanding Bonus Depreciation

Bonus depreciation is another fantastic way to accelerate your tax savings. It allows you to deduct a large percentage of an asset’s cost in the year it is first put into service. It’s beneficial for bigger companies making huge purchases.
Here’s what you should know about it:
- It’s Permanent & Restored: A new law has permanently reinstated 100% bonus depreciation for qualifying assets.
- No Spending Cap: Unlike Section 179, there’s no limit on how much you can spend to qualify. This makes it perfect for large purchases.
- It’s Automatic: While the deduction is widely available, you must actively elect to take it (or elect to opt out) on your tax return by filing the necessary forms.
- Used Assets: Good news! Bonus depreciation now applies to both new and used equipment.
Key Differences at a Glance

So, how do you decide which one is right for you? It helps to compare the main differences side by side.
- Total Deduction Limits: Section 179 has a fixed dollar limit each year, making it ideal for businesses with a clear budget for equipment. Bonus depreciation, on the other hand, has been permanently restored to a 100% deduction for qualifying assets and has no annual dollar limit, which is a massive advantage if you’re making a multi-million-dollar purchase.
- Spending Caps: Section 179 has a spending cap, which means the deduction starts to phase out if you spend too much on equipment. Bonus depreciation has no spending cap, making it a powerful tool for companies of all sizes, especially those with high-dollar purchases.
- Flexibility: Section 179 is an optional election you have to make on your tax form. This gives you flexibility. Bonus depreciation is automatic unless you actively opt out.
- Business Income & Losses: This is a key difference. With Section 179, your deduction is limited by your business’s taxable income; you can’t use it to create a loss. But with bonus depreciation, you can make or increase a net operating loss, which can then be carried forward to save you money in future tax years.
Which Is Right For You?
Choosing between them really comes down to your business and your spending habits.
- If you’re a small business making a few key purchases under the annual limit, Section 179 might be your best bet. It’s straightforward and gives you a powerful upfront deduction.

- If you’re a larger business making a significant investment, like a fleet of vehicles or a factory-sized machine, bonus depreciation is likely the better choice. It lets you deduct a large percentage without worrying about a spending cap.

The best part? You don’t always have to choose just one. In some cases, businesses can use both. They might apply the Section 179 deduction first, and then use bonus depreciation for any remaining cost.
Ultimately, both Section 179 and bonus depreciation are excellent tools for reducing your tax bill. By understanding their differences, you can make a smart, informed decision that benefits your bottom line. Remember to consult your tax professional to determine the best strategy for meeting your business needs.
