Section 179 or Bonus Depreciation? Equipment Write-Off Options in 2026
Many business owners know that equipment purchases can often be written off for tax purposes, but fewer understand how Section 179 and bonus depreciation actually work—or how they differ. They are not mutually exclusive, and although businesses often use one or the other, combining them can be a workable option depending on profitability, cash flow, and long-term planning goals.
Section 179: Immediate Deduction With Income Limits
Section 179 allows businesses to deduct the full cost of qualifying equipment in the year the equipment is placed in service rather than depreciating it over several years. This can significantly reduce taxable income for profitable businesses.
However, Section 179 comes with limitations. The deduction is generally limited to the amount of taxable business income. If a business does not have enough income, the full deduction may not be usable in the current year, though some amounts may be carried forward.
Section 179 also has annual limits and phase-out thresholds based on how much equipment is purchased during the year. Because of these limits, Section 179 is often most useful for small to mid-sized equipment purchases and businesses that are already profitable and looking to reduce taxable income.
Bonus Depreciation: Larger Write-Offs With Fewer Income Restrictions
Bonus depreciation also allows businesses to deduct a large portion of equipment costs in the first year, but it works differently from Section 179. Bonus depreciation is not limited by business income, which means it can create a net operating loss in some situations.
This makes bonus depreciation useful for businesses making large equipment purchases or businesses that want to accelerate deductions into the current year even if income is lower.
Bonus depreciation percentages have changed over time and continue to phase down under current tax law, which makes timing equipment purchases more important in some years.
You Can Use Section 179 and Bonus Depreciation Together
One of the most common misconceptions is that businesses must choose between Section 179 and bonus depreciation. In reality, many businesses use both in the same year.
For example, a business might use Section 179 to expense certain equipment up to the income limit and then apply bonus depreciation to additional equipment purchases. This allows business owners to manage taxable income more strategically rather than taking an all-or-nothing approach.
This type of planning is usually most effective when discussed before equipment is purchased, not after the fact when tax returns are being prepared.
Cash Flow Matters More Than the Tax Deduction
Buying equipment primarily for the tax write-off is not always a great idea for businesses. A deduction reduces taxable income, but it does not make the equipment free.
If a business buys a $50,000 piece of equipment, the tax savings may only be a fraction of that cost depending on the business’s tax rate. The remaining cost still has to be paid, often through financing or reduced cash reserves.
Equipment purchases should first make sense from an operational or revenue standpoint. The tax deduction should be viewed as an added benefit, not the main reason for the purchase.
Financing Equipment and Depreciation Timing
Many business owners are surprised to learn that equipment can often be deducted even if it is financed rather than paid for in cash. What matters most is when the equipment is placed in service, not when it is fully paid off.
This is why many equipment purchases happen toward the end of the year. Businesses review income, estimate taxes, and then decide whether equipment purchases make sense before year end.
Timing, financing terms, and expected income all play a role in deciding whether Section 179, bonus depreciation, or a combination of both makes the most sense.
Making the Right Decision for Your Business
Choosing how to write off equipment purchases is a tax decision, a cash flow decision, a financing decision, and a long-term planning decision. The best approach often depends on profitability, future income expectations, and how the equipment will be paid for.
