What changed, in plain terms
Two separate provisions govern how fast a business can write off equipment, and both got more generous heading into 2026. Under Revenue Procedure 2025-32, the Section 179 expensing limit for tax years beginning in 2026 rose to $2,560,000, with the deduction phasing out dollar-for-dollar once total qualifying property placed in service in the year passes $4,090,000. Separately, the One Big Beautiful Bill Act restored 100% bonus depreciation under Internal Revenue Code Section 168(k) for qualifying property acquired after January 19, 2025, and made it permanent, removing the phase-down schedule that had been shrinking bonus depreciation toward zero.
The two work together rather than against each other. Section 179 is capped and limited to business income; bonus depreciation has no dollar cap and is not limited to business income, which is why many businesses elect Section 179 on priority assets first and let bonus depreciation absorb the rest.
Why this matters specifically in Kern County
Oil and gas anchors a meaningful share of the regional economy here, with Chevron, Aera Energy, California Resources Corp, and a long list of smaller operators and service companies running equipment-heavy operations, and agriculture, particularly grapes, almonds, citrus, and pistachios, runs close behind. Both industries are capital-equipment intensive in a way that makes Section 179 and bonus depreciation genuinely consequential rather than theoretical: drilling and pumping equipment, trucks, and oilfield service machinery on one side, tractors, irrigation systems, and packing-house equipment on the other. Gulf Coast energy operators face the same swings, a pattern Corpus Tax Law sees around Corpus Christi.
That equipment intensity is also why a big write-off year can set up a worse year that follows. A business that expenses a large equipment purchase in full sees its taxable income drop sharply in the year of purchase. If revenue holds steady or grows the next year while the deduction is gone, the jump in taxable income can be significant, and a business that was not setting aside estimated payments for that swing can end up with a balance it did not expect.
Recapture is the part people forget
Section 179 and bonus depreciation both come with recapture exposure if equipment is sold, or its business use drops below 50%, before the end of its useful life. A rig, truck, or piece of farm equipment that gets written off in full and sold two years later can trigger recapture income in the year of sale, on top of whatever gain the sale itself produces. For operators who regularly turn over equipment, especially in the energy sector where asset churn is common, that is worth planning around before the deduction is taken, not after the sale closes.
Where this turns into an IRS collection problem
None of this changes anything about how the IRS collects once a balance exists. A Kern County Revenue Officer assigned to a case involving an oilfield service company or an agricultural operation does not care why the balance arose, only that it is unpaid. We have represented oilfield 1099 workers and operators across this region whose balances trace directly back to a year where income swung hard against a prior year's deduction, combined with payroll or estimated-tax deposits that slipped during the gap. The fix at that point is the same regardless of how the balance was created: file accurately, and negotiate the corrected number through an installment agreement or an Offer in Compromise sized to what the business can actually sustain.
Depreciation and Section 179 claims are also a routine area the IRS checks in Schedule F and business audits across the Valley, alongside equipment depreciation disputes, water-cost deductions, and seasonal labor classification. A properly substantiated deduction, equipment actually placed in service, business use documented, holds up fine. One built on an estimate or a purchase that technically closed after year-end does not, and that gap is exactly where an audit turns into a bigger assessment than the original return showed.
Planning the deduction, not just taking it
The larger limits do not require taking the maximum deduction every time equipment goes into service. For a business with volatile year-to-year income, which describes a large share of the oilfield service and agriculture operators in this region, spreading a deduction across Section 179, bonus depreciation, and ordinary MACRS depreciation can smooth taxable income instead of creating a sharp trough-and-spike pattern that drives estimated-payment problems the following year. That is a planning conversation worth having with a tax professional before the equipment purchase closes, not after the return is filed.
