Section 179 Fixed Asset Schedule: 2026 OBBBA Guide

Section 179 Fixed Asset Schedule: How the OBBBA’s $2,560,000 Limit Changes Accumulated Depreciation in 2026

When you elect Section 179 under the OBBBA’s new $2,560,000 limit, your fixed asset schedule must record the full cost basis, zero net book value, and $0 accumulated depreciation for that asset — while your California return follows a separate $25,000 cap. Failing to reconcile these two depreciation tracks creates a compliance gap that triggers FTB adjustments. As of June 2026, the federal vs. California divergence has never been wider.

The One Big Beautiful Bill Act (OBBBA) permanently expanded the Section 179 fixed asset schedule deduction limit to $2,560,000 for tax years beginning in 2026 — more than double the prior-law cap of $1,220,000. For Inland Empire business owners filing Form 1120-S, Form 1065, or Schedule C returns, this change reshapes how accumulated depreciation is recorded and reconciled between federal and California books. This guide, prepared by tax accountant Adham Abadier, CPA, explains exactly how the Section 179 election appears on your fixed asset register, why California forces a dual-track depreciation approach, and the five compliance steps to keep your records audit-ready in 2026.

What the OBBBA Changed for Section 179 in 2025–2026

New Dollar Limits Under §179

The One Big Beautiful Bill Act (OBBBA) permanently expanded Section 179 expensing, retroactive to tax years beginning after December 31, 2024. For tax years beginning in 2026, the maximum §179 deduction is $2,560,000 (per IRS Publication 946, updated for OBBBA inflation adjustments), with the phase-out threshold beginning at $4,090,000 of qualifying property placed in service — a full phase-out at $6,650,000. Before the OBBBA, the 2024 limit was $1,220,000. That’s a more than doubling of available first-year expensing for most small businesses.

What Qualifies for §179 in 2026

Qualifying property under IRC §179 and IRS Form 4562 includes: tangible personal property (equipment, machinery, computers, office furniture), off-the-shelf software, qualified improvement property (QIP), and certain vehicles. Real property improvements that qualify as QIP are now includable — a meaningful expansion for Inland Empire restaurant owners, medical offices, and retail buildouts in Moreno Valley, Riverside, and Corona who renovate leased space. The election is made annually on Form 4562, Part I, filed with your business tax return (Form 1120-S, 1065, or Schedule C).

§179 vs. Bonus Depreciation: Key Difference for Your Fixed Asset Schedule

Bonus depreciation under §168(k) restored to 100% for property acquired and placed in service after January 19, 2025 — but it is automatic (you must elect OUT), while §179 is an affirmative election. Bonus depreciation has no dollar cap, while §179 is capped at $2,560,000 for 2026 and limited to taxable income (per IRS Pub 946, Chapter 2). The choice between them — or combining them — directly determines how your fixed asset schedule and accumulated depreciation columns are populated.

Your fixed asset schedule is showing full cost basis with $0 accumulated depreciation after a §179 election — but your California return needs a completely separate depreciation track under FTB’s $25,000 limit. Adham reviews your fixed asset ledger and reconciles both tracks in a single call.

How §179 Elections Appear on Your Fixed Asset Schedule

The Three Columns That Change When You Elect §179

A properly maintained fixed asset schedule tracks: (1) asset description and date placed in service, (2) original cost basis, (3) accumulated depreciation to date, and (4) net book value (cost minus accumulated depreciation). When you elect §179 on an asset, the entire cost basis is expensed in Year 1. That means accumulated depreciation equals the full purchase price, and net book value drops to zero — all in the first year. Many Inland Empire business owners using our outsourced bookkeeping services are surprised to find their QBO fixed asset list still shows the asset depreciating over 5 or 7 years — a remnant of the default MACRS schedule that was never overridden after the §179 election.

A Concrete Example: Moreno Valley HVAC Contractor

A Moreno Valley HVAC contractor purchases a service truck and diagnostic equipment in March 2025 for a combined cost of $148,000. He elects §179 for the full $148,000 on his 2025 Schedule C. Here is what his fixed asset schedule must show at December 31, 2025:

• Cost basis: $148,000
• §179 expensing (accumulated depreciation, federal): $148,000
• Net book value (federal): $0
• California §179 allowed (state): $25,000
• California accumulated depreciation (MACRS 5-yr on remaining $123,000): ~$24,600 (Year 1 half-year convention at 20%)
• California net book value: $98,400

The result: two separate depreciation schedules for the same asset — one for federal Form 4562, one for FTB Form 3885A. If the bookkeeper only maintains one schedule, the California return is understated and the FTB will issue a deficiency notice.

How to Record §179 in Your Asset Register

1. Create the fixed asset record at full purchase price (e.g., $148,000).
2. Post a Year 1 depreciation entry equal to the §179 amount expensed on Form 4562 (federal track).
3. Create a separate depreciation schedule tab (or sub-account) for California — apply MACRS over the asset’s recovery period to the portion above the $25,000 California cap.
4. Reconcile both schedules annually at each tax year-end.
5. Flag the asset as “§179 expensed” in your asset register notes — this matters when the asset is sold (recapture rules under §1245 apply to the full federal §179 amount).

California Nonconformity: The State vs. Federal Depreciation Split

Why California Limits §179 to $25,000

California has not conformed to the OBBBA’s expanded §179 limits. Under the California Revenue and Taxation Code (R&TC), California’s §179 deduction is capped at $25,000, with a phase-out beginning at $200,000 of qualifying property (per FTB Form 3885A Instructions, 2025). California also does not allow bonus depreciation under §168(k) at all. This creates a mandatory addback on the California return for any federal §179 amount above $25,000, plus the full bonus depreciation amount. Our tax planning strategy team helps Inland Empire owners navigate these addbacks before they become FTB audit triggers.

The Depreciation Comparison: Federal vs. California

“The most common fixed-asset mistake I see on California S-Corp returns is a single depreciation schedule that mirrors the federal Form 4562. After a §179 election above $25,000, that approach understates California taxable income every year until the asset is sold — and then the recapture number is wrong too. Two schedules, every time, no exceptions.”

§179 Recapture and Your Fixed Asset Schedule at Disposition

What §1245 Recapture Means for §179 Assets

When you sell or dispose of an asset on which you claimed a §179 deduction, the IRS recaptures the full deducted amount as ordinary income under IRC §1245 — not capital gain. Your fixed asset schedule must show the original §179 amount taken so you (and your CPA) can calculate the correct recapture amount on Form 4797. The §1245 recapture rate is ordinary income tax rate — up to 37% federally in 2026, compared to the 0–20% long-term capital gain rate. A missing or wrong accumulated depreciation figure on the fixed asset schedule directly causes Form 4797 errors on the business tax return.

California Recapture Is Different

Because California allowed only $25,000 of §179 (not the full federal amount), your California adjusted basis in the asset will be higher than your federal basis. When the asset sells, California taxable gain will be lower than federal gain — but only if your fixed asset schedule correctly tracked both bases from Day 1. The FTB can and does audit basis calculations on asset dispositions. Inland Empire construction, trucking, and manufacturing companies — sectors with frequent equipment purchases and disposals — are particularly exposed to this dual-track error. If you’ve already filed returns with a mismatched schedule, our team can prepare amended tax returns to correct the California basis discrepancy.

Five Steps to Keep Your Fixed Asset Schedule Audit-Ready in 2026

The Section 179 Compliance Checklist

1. Maintain dual depreciation columns — one labeled “Federal” and one “California” for every asset with a §179 or bonus depreciation election.
2. Attach Form 4562 documentation to each asset record — the year elected, the amount elected, and the asset’s recovery class (5-yr, 7-yr, 15-yr QIP, etc.).
3. Reconcile accumulated depreciation to the balance sheet at each fiscal year-end — the sum of the accumulated depreciation column must tie to the “Accumulated Depreciation” contra-asset on your balance sheet.
4. Flag §179 assets separately in your register — tag them so that when any asset is sold or traded in, the preparer immediately knows a §1245 recapture calculation is required.
5. Prepare the FTB Form 3885 / 3885A separately — never import the federal Form 4562 numbers directly into the California return without adjusting for the §179 addback and the bonus depreciation addback.

If your current fixed asset register is out of sync — or you’ve never maintained dual federal/California tracks — our CPA services team can reconstruct your depreciation schedules back to the original §179 election year before the next filing deadline. We serve small businesses across Riverside, Corona, Eastvale, and all of the Inland Empire.

Get Your Fixed Asset Schedule Right Before Your Next Business Tax Return

The OBBBA’s expanded §179 limit is an opportunity — but only if your fixed asset schedule accurately tracks both the federal expensing and California’s separate MACRS depreciation track. A mismatched schedule leads to FTB addback errors, incorrect §1245 recapture on asset sales, and balance sheets that don’t tie to your tax returns. Inland Empire business owners filing 1120-S, 1065, or Schedule C returns face this dual-track problem on every equipment purchase over $25,000.
