A federal tax break does not always carry through to Oregon. For a business owner, the practical risk is estimating both tax bills from one federal number. Oregon’s 2026 legislation identifies differences involving bonus depreciation and qualified small business stock. Oregon Revenue legislative summary.
Can I deduct equipment in the same year on both returns?
A large federal deduction may leave you expecting a similar state saving. Check when each return allows the cost to be deducted before deciding how much cash to reserve for tax.
Depreciation spreads the cost of qualifying property over time. Federal bonus depreciation can accelerate deductions for eligible property; eligibility depends on the asset and relevant dates. It does not mean every business purchase is immediately deductible. IRS depreciation guidance.
Oregon identifies a bonus-depreciation disconnect for tax years 2026 and later. The useful question is not simply whether the federal deduction is large. It is how much depreciation Oregon allows for that asset in that year, and how later deductions and the remaining tax basis—the property’s cost after tax adjustments—must be tracked separately.
A simplified equipment example: Assume a sole proprietor buys and begins using $50,000 of qualifying five-year equipment in January 2026, entirely for business. Assume it qualifies for 100% federal bonus depreciation, no Section 179 deduction is elected, and the ordinary half-year depreciation method applies. That method treats the equipment as used for half its first year and normally gives a 20% first-year deduction for this class of equipment.
The federal deduction would be $50,000. Without bonus depreciation, the ordinary first-year deduction would be $10,000: $50,000 × 20%. The difference is $40,000 more income in the Oregon calculation that year, before other adjustments. That is extra taxable income, not a $40,000 tax bill. The state tax effect depends on the owner's actual rates and return.
These assumptions keep the example simple. Different equipment, purchase dates, business use or deduction elections can change the result. Section 179 is a separate rule that can allow eligible purchase costs to be deducted sooner; this example does not claim it. IRS equipment and depreciation rules, including Table A-1; Oregon SB 1507, sections 7 and 9.
Keep an asset-by-asset record of cost, purchase date, date it became ready and available for business use (the placed-in-service date), business use, federal deduction, Oregon deduction, and remaining basis. Timing differences should be tracked into later years rather than treated automatically as a permanent loss of the whole deduction.
If I sell my business, will Oregon allow the same tax break as the IRS?
First identify what is being sold and which federal rule applies. A stock-sale exclusion removes eligible gain from taxable income; it is not a general exemption for every business sale.
Qualified small business stock is a specific category of corporate shares that meets federal requirements. Some eligible sellers can exclude qualifying gain under Section 1202. It is not a general exemption for every small-business or LLC sale.
For tax years beginning in 2026 or later, Oregon's enacted SB 1507 requires an individual taxpayer to add back gain excluded federally under Section 1202. The provision covers the federal exclusion, not just the extra benefit created by the 2025 federal changes. Thus a federally tax-free stock gain can still increase Oregon taxable income. Stock eligibility and the amount of federal gain excluded still need their own calculation. Enacted bill, sections 5 and 10.
What should I bring to an accountant before buying equipment or selling?
The accountant needs the details behind the federal figure to work out the state result.
Bring the federal depreciation schedule and any stock-sale analysis, not just the profit-and-loss total. Ask for an Oregon calculation before deciding what cash to reserve. An employee with only wages generally does not need these business provisions, but a wage earner with a side business may.
A separate federal and Oregon estimate helps you see whether a deduction is delayed or a federal exclusion is unavailable on the state return.
How should I use this information?
These examples help you anticipate tax questions and prepare for a conversation with a qualified accountant. Each person’s or couple’s circumstances are different. Before acting, ask an accountant to apply the rules for your year and situation; timely advice may save thousands of dollars and make the decision easier.
