Frequently Asked Questions

What types of equipment qualify for Section 179?

Most tangible personal property used in business qualifies, including computers, machinery, vehicles, and office furniture. The equipment must be purchased and placed in service during the tax year. Software and certain improvements to nonresidential real property may also qualify.

Can I deduct more than the equipment cost?

No, the total deduction cannot exceed the actual equipment cost. Additionally, the deduction is limited to your business taxable income. Any unused portion can be carried forward to future tax years, providing flexibility for businesses with fluctuating income.

How does bonus depreciation interact with Section 179?

Bonus depreciation applies to the remaining basis after Section 179 is applied. For 2024, the bonus rate is 60%. This means if you have $50,000 remaining after Section 179, you get an additional $30,000 deduction, reducing your depreciable basis further.

Additional Guidance

For maximum benefit, coordinate Section 179 elections with your overall tax strategy. Consider your marginal tax rate when evaluating the true value of deductions. Businesses with consistent income may benefit from maximizing current deductions, while growing businesses might prefer spreading deductions over multiple years. Always verify current year limits with IRS publications or a qualified tax advisor, as these figures are subject to annual adjustment.
