  • The asset must be used over 50% for business and placed in service during the tax year. Section 179 cannot create a loss; the excess carries forward. Depreciation recapture applies on sale: ask your accountant.
  • Reference 2026 limits are editable; confirm with the IRS.

How it works

  1. Enter the cost, business use and asset type.
  2. Enter your business income and tax rates.
  3. Review the Section 179 limits.
  4. Read the year-1 savings and the year-by-year comparison.

Two ways to deduct fast

Section 179 lets you expense qualifying equipment in the year it is placed in service, limited by your business income. Bonus depreciation can then deduct a large share of what remains.

Timing, not free money

Faster deductions move tax savings earlier but reduce later depreciation. The present-value line shows the benefit of getting them sooner.
