CapEx vs OpEx: Expense Classification

Written by Aparna Devalla, CPA

Curated by Rubric Financial

1 / 4

Definitions and Tax Implications

  • Capital expenditures (CapEx) are costs that create or improve long-term assets, recorded on the balance sheet and depreciated or amortized over their useful life.
  • Operating expenditures (OpEx) are day-to-day costs of running the business, fully expensed on the income statement in the period they are incurred.
  • CapEx reduces taxable income gradually through depreciation deductions over multiple years, while OpEx provides an immediate deduction in the current year.
  • The classification directly impacts your reported profitability, tax liability, and cash flow statement presentation.
