Section 179 Deduction Overview

The Section 179 deduction is a tax benefit that allows businesses to deduct the full cost of qualifying equipment and software in the year it’s placed into service, rather than depreciating it over several years. This can significantly reduce taxable income and lower your overall tax bill. However, you cannot use a Section 179 deduction to create a net business loss.

How Section 179 Works

Normally, when you buy business equipment, the IRS requires you to spread the cost over its useful life (depreciation). Section 179 lets you:

• Deduct all or part of the purchase price upfront
• Apply the deduction in the same tax year the asset is used
• Improve cash flow by lowering current-year taxes

Key Benefits

• ✅ Immediate tax savings instead of long-term depreciation
• ✅ Improves cash flow for reinvestment in your business
• ✅ Encourages upgrades to equipment, machinery, and technology
• ✅ Applies to both new and used qualifying assets

What Qualifies for Section 179

Eligible property generally includes tangible business assets such as:

Equipment & Machinery

• Manufacturing equipment
• Tools and heavy machinery
• Office equipment

Vehicles (with limitations)

• Business-use vehicles
• SUVs and trucks (subject $31,300 cap)

Technology & Software

• Computers and laptops
• Off-the-shelf software
• Office systems

Certain Property Improvements

• Qualified improvements to non-residential buildings (e.g., HVAC, roofing, security systems)

Annual Limits and Phase-Out

Section 179 comes with annual limits that may change each tax year. Typically:

• There is a maximum deduction limit
• There is a spending threshold, after which the deduction begins to phase out

👉 If your total qualifying purchases exceed the threshold, your deduction is gradually reduced.

Important Rules to Know

1. Business Use Requirement

The asset must be used more than 50% for business purposes.

2. Taxable Income Limitation

You can only claim Section 179 up to your business taxable income.

• You generally cannot create a loss with Section 179
• Any unused amount may be carried forward

3. “Placed in Service” Rule

The equipment must be purchased and actively used in the tax year you’re claiming the deduction.

Section 179 vs. Bonus Depreciation

💡 Many businesses use both methods together for maximum tax benefit.

Example

A business purchases $50,000 worth of equipment:

• With standard depreciation: Deduct over several years
• With Section 179: Deduct up to the full $50,000 immediately (subject to limits)

When Section 179 May Not Be Ideal

Section 179 may not always be the best choice if:

• Your business has low or no taxable income
• You expect higher future income and tax rates
• You want to spread deductions over time

How to Claim Section 179

To take the deduction, go to:

1. Federal > Income
2. Choose to select your forms, then continue
3. Choose and edit the Schedule you are depreciating for
4. Select Depreciation
5. Assets
6. Enter the information for the asset you are depreciating, then enter your Section 179 deduction in the box labeled "Section 179 deduction"

Deduction Limits for Vehicles

Certain vehicles are not subject to the section 280F depreciation limits:

• Autos with unloaded gross vehicle weight (GVW) of more than 6,000 lbs.
• Trucks and vans with loaded GVW more than 6,000 lbs.
• Qualified nonpersonal-use vehicles.

Even if business use exceeds 50%, the taxpayer may elect to depreciate using the 5-year rule for straight-line depreciation.
