Section 179 lets a business deduct the full purchase price of qualifying equipment in the year it's placed in service, instead of depreciating it over years — up to an annual limit that's indexed each year (well over $1 million in recent years). It applies to new-to-you equipment, so quality used gear can qualify too. Always confirm the current-year cap and your eligibility with a tax professional.
