2026 Bonus Depreciation Phase-Down: Section 179

The Sunsetting Era of 100% Bonus Depreciation

For years, software founders, content creators, and online entrepreneurs enjoyed one of the most generous tax provisions in modern corporate history: 100% first-year bonus depreciation enacted under the 2017 Tax Cuts and Jobs Act (TCJA). Whether purchasing high-end developer workstations, studio camera gear, podcast setups, or warehouse servers, business owners could write off the entire purchase price in Year 1 on Form 4562.

That era is now coming to an end. Under statutory phase-down rules, bonus depreciation dropped to 80% in 2023, 60% in 2024, 40% in 2025, and now stands at 20% in 2026 (heading toward 0% in 2027 unless extended by Congress). However, smart entrepreneurs do not need to settle for a fractional write-off. By pairing remaining bonus depreciation with IRC Section 179 Expensing, business owners can still achieve 100% upfront write-offs.

Tax Year	Bonus Depreciation Rate	First-Year Deduction on $10,000 Tech Asset	Remaining MACRS Multi-Year Depreciation
2022 & Prior	100% Upfront	$10,000 (Full 100% deduction)	$0
2023	80% Phase-Down	$8,000 upfront + $400 MACRS	$1,600 over remaining useful life
2024	60% Phase-Down	$6,000 upfront + $800 MACRS	$3,200 over remaining useful life
2025	40% Phase-Down	$4,000 upfront + $1,200 MACRS	$4,800 over remaining useful life
2026 (Current)	20% Phase-Down	$2,000 upfront + $1,600 MACRS	$6,400 over 5-year MACRS schedule
2027+	0% (Expired)	$0 upfront ($2,000 standard MACRS)	$8,000 over 5-year MACRS schedule

The Solution: Maximizing Section 179 Expensing in 2026

While bonus depreciation is fading, Section 179 remains a permanent part of the Internal Revenue Code. For 2026, Section 179 permits eligible businesses to deduct up to $1,220,000+ in qualifying property upfront in the year placed in service, subject to annual inflation adjustments.

Worked Example: Tech Setup Tax Strategy in 2026

Consider a self-employed software engineer or digital creator purchasing $15,000 of qualifying business assets in 2026 (a $5,000 custom developer PC, $4,000 4K video studio camera setup, and $6,000 in office furniture and servers). The consultant generates $130,000 in net Schedule C income.

Deduction Strategy	Year 1 Write-Off	Immediate Tax Savings (32% Effective Bracket)	Multi-Year Depreciation Carryover
Standard 5-Year MACRS Only	$3,000 (20% first year)	$960.00	$12,000 over remaining 4 years
2026 Bonus Depreciation Only (20%)	$5,400 ($3k bonus + $2.4k MACRS)	$1,728.00	$9,600 over remaining 4 years
Electing Section 179 (100%)	$15,000.00 (Full 100% Write-Off)	$4,800.00 Immediate Savings	$0 (Full write-off captured in 2026)

By electing Section 179 on Form 4562, the taxpayer captures an immediate $4,800 tax savings in 2026 rather than waiting five years to deduct their equipment. Review federal tax bracket thresholds in our Federal Tax Calculator Guide and our breakdown on Self-Employment Tax for Solopreneurs.

Important Differences: Section 179 vs. Bonus Depreciation

• Income Limitation: Section 179 cannot create or expand a Net Operating Loss (NOL); you can only deduct up to your net active business profit (excess carries forward indefinitely). Bonus depreciation can create a business tax loss.
• Used Equipment Qualification: Both Section 179 and bonus depreciation apply to new and "new-to-you" used equipment, provided the asset was acquired in an arm's-length commercial transaction.
• Business Use Percentage Rule: Qualifying assets must be used more than 50% for business. If business use drops below 50% in future years, depreciation recapture is triggered.

State Tax Non-Conformity and Section 179 Decoupling

One of the most complex aspects of depreciation tax planning is state conformity. While federal law permits up to $1,220,000 in Section 179 write-offs, several major states "decouple" from federal rules:

• California Section 179 Cap: California limits annual Section 179 expensing to only $25,000 per year, and completely disallows bonus depreciation. If you write off a $50,000 server federally, you can only write off $25,000 on your California return, depreciating the remainder over multi-year state schedules.
• New York and Other Non-Conforming States: Certain states require complex adjustments and addition modifications on state tax returns when claiming federal accelerated depreciation.
• Record-Keeping Dual Schedules: Maintain dual depreciation schedules (Federal MACRS vs. State MACRS) within your accounting software to avoid audit penalties upon asset disposal or business sale.

Conclusion

While the phase-down of bonus depreciation to 20% in 2026 changes the tax landscape, entrepreneurs who proactively utilize Section 179 expensing can still claim 100% upfront write-offs on business equipment, software, and tech gear.
