Can musicians deduct guitar strings and studio time?

Yes — often, if the musician is operating as a real business and the expenses are ordinary and necessary for that business. In the U.S., that typically means self-employed musicians, independent contractors, sole proprietors, and some LLCs taxed as disregarded entities may be able to deduct items like guitar strings and studio time.

A few important caveats:

• Guitar strings are usually treated as a supplies or consumables expense.
• Studio time is generally deductible as a business expense, but the exact tax category can depend on how it is billed and how your records are kept.
• If the activity is treated as a hobby rather than a business, deductions are generally much more limited or unavailable.
• Keep receipts, invoices, and other records showing the business purpose of each expense.
• If you are a W-2 employee, the rules are different, and unreimbursed employee expense deductions are generally not available on federal returns under current U.S. law.
