Yes — sound equipment, instruments, and travel to gigs are deductible business expenses for independent DJs and musicians, but personal listening gear or instruments you don't use professionally don't qualify.

Bigger purchases, like a full sound system, may qualify for Section 179, allowing you to deduct the full cost immediately in the year
