Pick Section 179 or spread depreciation

Big purchases give you a choice: deduct the full cost now under Section 179 or spread depreciation over years. The right call depends on this year's profit.

Pick Section 179 or spread depreciation

Why this matters

When you buy equipment, you choose how fast to deduct it, all at once or over several years. Tax software may present a default choice. Taking everything now can help current cash flow, but spreading deductions across future years may be more valuable if this year's tax rate is low and future rates are higher.

What "done" looks like

  • Every significant asset is listed with a deliberate method: Section 179, bonus depreciation, or regular MACRS
  • You compared this year's tax rate against expected future years
  • Business-use percentage is documented for mixed-use assets like vehicles
  • The depreciation schedule is saved for future years

How to do it

  1. List every asset purchase with cost and in-service date.
  2. Check current limits, the 2025 tax law raised Section 179 expensing to $2.5 million and restored 100% bonus depreciation for qualifying property.
  3. Review both scenarios with tax software or a tax professional: full expensing now versus spreading deductions over time.
  4. Deduct less now if income is low, the same deduction is worth more in a high-bracket year.
  5. Flag vehicles and mixed-use assets, business use below 50% changes the rules and can trigger recapture.

Common mistakes

  • Expensing everything in a low-income year when spreading the deductions could provide more tax value
  • Forgetting Section 179 can't create a loss from business income (bonus depreciation can)
  • Losing the depreciation schedule and re-guessing basis years later

Real-world examples

  • The One Big Beautiful Bill Act (July 2025) raised the Section 179 cap to $2.5 million and made 100% bonus depreciation permanent for qualifying property acquired after January 19, 2025.
  • The IRS de minimis safe harbor lets most small businesses expense items under $2,500 outright, skipping depreciation entirely.

From a founder's point of view

The instinct is to grab every deduction immediately, but depreciation is one of the few places where tax timing is a real lever. The question isn't "can I deduct this now", it's "which year does this deduction buy the most."

Rule of thumb

If this year's tax rate is the highest you expect for a while, expense now; if this year is unusually lean, spread it out.
