Section 179 Tax Deduction on Surface Prep Equipment

⏰ Year-End Deadline: To qualify for the deduction on this year’s taxes, equipment must be purchased and placed into service by December 31, 2026. Don’t wait until the last minute — lead times and shipping can affect whether your machine is “in service” by the deadline.

If you’ve been thinking about adding a grinder, shot blaster, or dust collector to your operation, buying before year-end could let you write off the cost on this year’s taxes thanks to the Section 179 tax deduction. Here’s a plain-English guide to how it works — and how it can make that equipment purchase a lot more affordable.

Please note: This page is general information, not tax advice. Always confirm the details and your eligibility with your own tax professional or accountant.

What Is the Section 179 Tax Deduction?

Normally, when your business buys equipment, you deduct the cost gradually over several years through depreciation. Section 179 lets you deduct the full purchase price of qualifying equipment in the same year you buy it — instead of spreading it out.

That means if you purchase a qualifying concrete grinder or dust collector this year and put it to work, you may be able to deduct the entire cost from your business income on this year’s tax return. For contractors and small businesses, that’s immediate tax relief that frees up cash to reinvest in your work.

How Does Section 179 Work?

Here’s the difference in simple terms:

• Without Section 179: Buy a $50,000 machine, deduct a portion each year over five or more years.
• With Section 179: Buy that same $50,000 machine, and deduct the full amount this year (up to the annual limit).

The deduction is designed especially to help small and mid-sized businesses invest in the equipment they need. For 2026, the limits are:

• Deduction limit: Businesses can deduct up to $2,560,000 of qualifying property for the 2026 tax year.
• Phase-out threshold: The deduction begins to phase out once total equipment purchases exceed $4,090,000, and is fully eliminated at $6,650,000.

For most contractors and small businesses, these limits are far more than you’ll spend — which means your equipment purchase will typically qualify for the full deduction.

(These figures apply to the 2026 tax year. Always confirm current limits and your eligibility with your tax professional.)res change year to year — confirm the current limits with your tax professional.)

What Equipment Qualifies?

Equipment doesn’t have to be brand new — it just has to be new to your business and placed into service during the tax year you’re claiming it. Qualifying business equipment generally includes machinery and tools used for commercial purposes, including equipment bought with qualified financing.

Surface prep equipment from Substrate Technology that may qualify:

• Concrete floor grinders — Prep/Master and Lavina planetary grinders
• Shot blasters — IMPACTS surface prep machines
• Dust collectors — Ruwac and Prep/Master industrial units
• Scarifiers
• Floor strippers
• Hand grinders
• Swing machines and other equipment

(Consumable diamond tooling is typically expensed separately — ask your accountant.)

Financing still qualifies: Even if you finance the equipment, you may still be able to deduct the full price under Section 179. That means you could write off the whole machine while only having paid part of it — ask us about our financing packages.

How to Claim Section 179

1. Confirm your equipment qualifies — new to your business, used for business, placed in service this tax year.
2. Put it to work this year — the deduction applies only if it’s actively used for business during the tax year.
3. Keep your records — purchase receipts, financing agreements, and usage documentation.
4. File IRS Form 4562 with your business tax return to claim the deduction.

Your accountant can handle the paperwork — the important thing on your end is to purchase and receive the equipment in time to put it in service by December 31.

Section 179 FAQs

Can I write off a concrete grinder or shot blaster on my taxes? In most cases, yes — qualifying business equipment can be deducted under Section 179 (or bonus depreciation, or both). Confirm with your tax professional.

Do I have to buy new equipment? No. It must be new to your business and placed into service in the tax year — new or used can qualify.

Does financed equipment still qualify? Generally yes. You may be able to deduct the full purchase price even if you financed it — one of the biggest advantages of Section 179.

What’s the deadline? Equipment must be purchased and placed into service by December 31 to count for that tax year. Don’t cut it close — order early so shipping and setup don’t push you past the deadline.

Does consumable tooling qualify? Diamond tooling and other consumables are usually expensed separately, not under Section 179. Ask your accountant.

Is there a limit to how much I can deduct? For 2026, you can deduct up to $2,560,000 of qualifying property, with the deduction phasing out above $4,090,000 in total purchases (and fully eliminated at $6,650,000). For most contractors, that means your purchase qualifies for the full deduction.
