The Creative’s Guide to Writing Off Everything (Legally)

Tax season hits different when you work for yourself. No W-2, no HR quietly handling your withholdings, just you, a shoebox of receipts, and the creeping sense you’re leaving money on the table.

You probably are. Schedule C filers routinely under-claim the two biggest deductions on offer, the home office and the vehicle/mileage write-offs, for no better reason than they didn’t track them or assumed they didn’t qualify. Stack a few strategies your tax software never mentions on top, and there’s real money sitting there for most creatives running their own shop.

This isn’t tax advice, it’s a map. Bring it to your CPA and ask, “does this apply to me?”

The one rule that actually matters

Before any list means anything, know the test the IRS actually uses: an expense is deductible if it’s ordinary (normal for your line of work) and necessary (helpful and appropriate for running the business). That’s the whole thing. There’s no secret pre-approved checklist, just that test, applied honestly.

The foundation: everyday write-offs

The ones most of us already know about, and still fail to track well enough to fully claim.

Home office. A space used only for work is deductible two ways, the simplified method ($5/sq ft up to 300 sq ft) or actual expense (the share of your home’s square footage used for business, applied to rent, utilities, insurance, and repairs). Actual usually wins if you run the numbers; most people pick simplified because it’s easier, not because it pays more.

Phone & internet. The business-use share of your cell and home internet counts. A dedicated business line is 100%.

Software & subscriptions. Every tool you run the business on, design apps, project management, cloud storage, hosting, email, is fair game.

Vehicle mileage. Business driving (not your commute), via the standard mileage rate or actual costs. Track it. Skip it and you’re leaving hundreds, sometimes thousands, on the table every year.

Health insurance premiums. Self-employed, paying your own coverage, not eligible for an employer’s or spouse’s plan? Premiums come off the top as an above-the-line adjustment. Missed constantly.

Education & professional development. Courses, certs, books, and conferences that maintain or sharpen skills for your current business, not for launching a new, unrelated one.

Office supplies. Paper, ink, notebooks, shipping and packaging. Small on their own, real over a year, forgotten because no single receipt feels big enough to log.

Bank & processing fees. Account fees, wire fees, and the cut Stripe/Square/PayPal skim off every payment. Nobody totals these because they vanish before the money even lands.

Professional services. Your accountant, bookkeeper, lawyer. Which means paying for help with your taxes pays for a slice of itself.

Business insurance. Liability, professional/E&O, and equipment coverage, standard, and skipped because the premium hits quarterly or yearly instead of monthly.

Advertising & marketing. Paid ads, business cards, a site redesign, a portfolio’s hosting bill, anything spent to get or keep clients.

Contract labor. Pay another freelancer, editor, VA, or contractor for client work and it’s deductible (issue a 1099-NEC if it’s $600 or more for the year).

Memberships & dues. Trade associations, industry orgs, and professional communities you pay into.

Interest on business debt. Interest on a business card or a business-purpose loan. The purchases already counted; the interest is a separate, ongoing line people forget.

How we actually did it, the New York years

Back when Therum was one person freelancing in New York, none of this was theory. It was just how the taxes got done every year.

Home office. We measured the work area against the total square footage of the apartment. That ratio became the percentage we applied to rent and utilities.

Subscriptions. Every monthly tool that actually ran the business, no exceptions, no guessing, got logged and written off.

The phone. It was getting paid off over time, so instead of one big purchase it was a recurring monthly cost. A business tool, so that monthly payment counted as a business expense, not just the “buy a new phone” moment.

The laptop. Bought outright, and it still counted, partly through the upgrades and repairs put into it after, partly through depreciation. The math: take the total cost, divide by the years of useful life (computers are usually depreciated over 5), and that’s the deductible amount for the year; divide by 12 for a monthly figure. That’s straight-line depreciation, the simplest version of a method with a few variations. Confirm the exact schedule with a CPA, but the core math is that simple.

Meals and client costs. Anything tied to actually running client relationships, meals with clients, things bought specifically because of an engagement, got tracked and written off too (meals are typically 50% deductible, so keep that in mind).

None of it took exotic strategy. Know what counts, track it consistently, and don’t let “I already own it” or “it’s just a small monthly charge” talk you out of a cost that’s legitimately part of doing business.

The stuff most people don’t know about

This is where talking to an actual accountant, or reading what accountants say when they’re not billing by the hour, pays off.

The Augusta Rule. Section 280A(g) lets you rent your own home to your business for up to 14 days a year, completely tax-free on the income side, while the business deducts the rent as a legitimate expense. Built for homeowners renting out during the Masters, now used by owners who host meetings, retreats, or planning sessions at home. It needs real documentation, a market-rate lease, an actual business purpose, a paper trail, so it’s a talk-to-your-CPA-first move, not a DIY one.

Hiring your kids. If your children do real work for the business, you can pay them a real wage, and that wage is deductible. Depending on your structure and their age, that income may owe no income tax on their end up to the standard deduction. Legit income-shifting, with real rules around genuine work and proper payroll docs.

Bad debt. A client stiffs you on an invoice you already reported as income, and you made real attempts to collect? That unpaid amount may be deductible as a bad debt.

Section 179 / bonus depreciation. Big buys, computers, cameras, furniture, don’t always have to crawl through years of depreciation. Section 179 often lets you deduct the full cost in the year you bought it.

Retirement contributions. A SEP IRA or Solo 401(k) works both ends: it lowers your taxable income now and builds your future at the same time. Chronically skipped by freelancers who assume retirement accounts are an employer thing.

Startup costs. The first $5,000 spent getting the business off the ground, before you earned a dime, is often deductible in year one, with the rest amortized over time.

Where people get in trouble

The theme in every honest CPA’s advice: freelancers don’t over-claim, they under-claim, out of fear of an audit. But under-claiming costs too, it’s just invisible, because you never see the money you didn’t get to keep. The fix isn’t guessing harder. It’s documentation:

A separate business bank account and card. Mixing personal and business spending is the #1 thing that turns a legitimate deduction into an audit risk.

A mileage log, even a simple app-based one.

Receipts, digitized as you go, not reconstructed in March.

A home office that’s actually, exclusively used for work, not the kitchen table.

The real takeaway

None of this is about being clever with the IRS. It’s understanding that the code already hands self-employed people tools W-2 employees never get, you just have to know they exist and use them honestly. The creatives who save the most didn’t find a loophole. They tracked everything and asked their accountant “wait, can I write that off?” one extra time a year.

Talk to a CPA before you file. This is meant to make that conversation sharper, not replace it.
