What Does “Ordinary & Necessary” Mean for a Deduction?
It’s the two-word test the IRS uses to decide whether a business expense counts. Pass it and you can write the cost off; fail it and you can’t.
To be deductible, a business expense has to be both “ordinary” and “necessary.” Ordinary means it’s common and accepted in your line of work. Necessary means it’s helpful and appropriate for running your music business — it does not have to be indispensable.
What each word actually means
Ordinary is about your industry, not just you. Studio time, mixing, mastering, beats, distribution fees, promo, gear — these are all normal costs of being a recording artist, so they clear the “ordinary” bar without a fight. The question is always: would other people doing what you do reasonably spend money on this?
Necessary is a lower bar than the word sounds. The IRS treats it as “helpful and appropriate” for the business — not “you would have gone under without it.” A better microphone is necessary in this sense even though you technically already owned one.
The line that trips artists up: business vs. personal
The real test in practice isn’t ordinary vs. necessary — it’s business vs. personal. An expense is only deductible to the extent it’s for the business. A few rules of thumb:
- Purely business — a pop filter, a distribution fee, a session musician you paid — is fully deductible.
- Mixed-use — your phone, your laptop, your car — is deductible only for the business-use share. If the laptop is 70% music and 30% personal, you deduct 70%.
- Purely personal — groceries, everyday clothes, your commute — never becomes deductible just because you’re self-employed.
Two more things the expense has to be
Even an ordinary-and-necessary cost can be knocked out if it’s not reasonable in amount (wildly lavish spending draws scrutiny) or if it’s really a capital purchase — a big, long-lasting item like a $2,000 interface — which follows its own rules instead of a plain one-year write-off. That’s a chapter of its own.
