Equipment & Section 179 Deduction California

Equipment and Depreciation Deductions in California: The Complete Guide

When you buy equipment, furniture, vehicles, or other business assets, you generally cannot deduct the full cost in the year of purchase — you must depreciate it over its useful life. But there are important exceptions: Section 179 and bonus depreciation allow you to deduct all or most of the cost in year one. The catch in California: the state does not conform to federal bonus depreciation at all, and California's Section 179 limit is far lower than the federal limit. Understanding these differences is critical to accurate tax planning and avoiding FTB adjustments.

Section 179: Immediate Expensing of Business Assets

Section 179 allows businesses to deduct the full cost of qualifying assets in the year they are placed in service, rather than depreciating them over multiple years. This is a powerful cash flow tool — instead of deducting $10,000 per year for 7 years on a $70,000 piece of equipment, you deduct the entire $70,000 in year one.

The California Section 179 limit of $25,000 means that for any asset purchase above $25,000, the excess must be depreciated under MACRS on the California return even if you took the full deduction federally. This creates a California-federal timing difference that must be tracked in your records and reconciled on Schedule CA each year.

Bonus Depreciation: Federal Only — California Does Not Conform

Federal bonus depreciation (IRC Section 168(k)) allows businesses to deduct a percentage of the cost of new qualifying assets in the year of purchase. For 2024, the federal bonus depreciation rate is 60%. For 2025, it drops to 40%. For 2026, it drops to 20% before phasing out entirely under current law (though the OBBBA may extend or modify this).

California does not allow bonus depreciation at all. This is one of the most significant California non-conformity items. If your accountant is claiming bonus depreciation on your California return, that is an error that will trigger an FTB adjustment, back taxes, and interest.

MACRS Depreciation: The Default Method

For assets that do not qualify for Section 179 or bonus depreciation (or where those elections are not made), the default method is MACRS — the Modified Accelerated Cost Recovery System. MACRS assigns each asset to a recovery period based on its type:

MACRS uses the double-declining balance method for most personal property, which front-loads depreciation in the early years. California conforms to MACRS recovery periods and methods — the only difference is the Section 179 limit and the absence of bonus depreciation.

California Non-Conformity: What It Means for Your Tax Return

The California-federal depreciation difference is one of the most common sources of FTB adjustments. Here is how it plays out in practice:

Example: You buy a $100,000 piece of equipment in 2024. Federally, you take $100,000 Section 179 deduction in year one (within the $1,220,000 limit). On your California return, you can only take $25,000 Section 179 — the remaining $75,000 must be depreciated over 7 years under MACRS. Year one California depreciation on the $75,000 balance: approximately $10,700. So your federal deduction is $100,000 and your California deduction is $35,700 — a $64,300 difference that is fully taxable in California.

This difference reverses over time as California catches up through depreciation, but in the year of purchase, it creates a significant California tax liability that many business owners do not anticipate.

Vehicle Depreciation: Special Limits Apply

Passenger vehicles (cars, light trucks, and vans under 6,000 lbs GVWR) are subject to annual depreciation caps — the "luxury auto" limits. For 2024, the annual depreciation limit for passenger vehicles is $12,400 in year one (with bonus depreciation), $19,800 in year two, $11,900 in year three, and $7,160 in subsequent years. These limits apply regardless of the vehicle's actual cost.

Vehicles over 6,000 lbs GVWR (most full-size trucks, SUVs, and vans) are not subject to these limits and qualify for full Section 179 treatment. This is why many business owners choose heavy SUVs and trucks — the tax treatment is significantly more favorable.

Action Steps

1. Track every asset purchase separately — you need the date placed in service, cost, and business-use percentage for each item
2. Do not assume your California depreciation matches your federal depreciation — it almost never does for businesses with significant asset purchases
3. Consider a cost segregation study for commercial real estate purchases — it can accelerate depreciation significantly
4. Evaluate Section 179 elections before year-end — the election must be made on a timely filed return

Frequently Asked Questions

Does California allow Section 179?

Yes, but with a much lower limit than federal law. The California Section 179 limit is $25,000 (with a phase-out starting at $200,000 in asset purchases), compared to the federal limit of $1,220,000. Any Section 179 deduction above $25,000 taken federally must be depreciated under MACRS on the California return.

What is the difference between Section 179 and bonus depreciation?

Both allow accelerated first-year deductions, but they work differently. Section 179 is an election to expense qualifying property up to a dollar limit. Bonus depreciation is a percentage-based first-year deduction that applies automatically to new qualifying property (unless you elect out). California allows Section 179 (with lower limits) but does not allow bonus depreciation at all.

Can I deduct software as equipment?

Yes — off-the-shelf software (not custom-developed) qualifies for Section 179 treatment and can be deducted immediately. Custom software is depreciated over 36 months. Subscription-based software (SaaS) is deducted as an ordinary business expense in the year paid, not depreciated.
