What can you actually write off as a freelancer?

Let's start with the one rule behind all of this.

Before you write anything off, it has to pass one simple test. 

The IRS says an expense has to be ordinary (common in your line of work) and necessary (helpful and appropriate for your business).

That's it. That's the whole rulebook. Keep those two words in your back pocket and you'll almost always know whether something counts.

Two myths, busted

Myth 1: "A deduction is a deduction. It's the same for everyone."

Nope. A deduction is actually worth more to you as a freelancer than it would be to someone with a regular job. Here's why. When you write off a business expense, it lowers your net profit and your net profit is the number both your income tax and your 15.3% self-employment tax are based on. 

So a $1,000 deduction saves you income tax plus around $140 in self-employment tax that an employee would never get back. Same expense, bigger payoff. That's your reward for being the boss.

Myth 2: "A write-off means it's basically free."

This one trips people up all the time. A write-off does not mean the money magically comes back to you. You still spent it. What it means is that you don't get taxed on money you already spent to run your business. Think of it this way: if you spend $500 on a work laptop, you're not getting $500 back — you're just not paying tax on that $500 as if it were profit sitting in your pocket. It isn't. You spent it earning a living.

Okay, let's get to the money.

Here's a deduction that's practically automatic, yet people miss it constantly.

When you're self-employed, you pay that 15.3% self-employment tax. But the government lets you deduct half of it right back off your taxable income.

Why do people miss it? Because they think of it as a tax they pay, not a deduction they get. It feels like a bill, so nobody expects a gift hiding inside it. But it's there, iit lands on Schedule 1, line 15, and you don't need to itemize to claim it.

If you pay for your own medical, dental, or qualifying long-term-care coverage  - for you, your spouse, or your dependents - you can likely deduct those premiums.

This is one of the biggest deductions freelancers qualify for and don't claim, so pay attention here. And the best part: you get it even if you take the standard deduction.

A couple of catches to keep it honest:

• You can only deduct up to the net profit of the business the plan is tied to.

• You generally can't claim it for any month you were eligible for an employer's plan — including your spouse's employer's plan.

The form that figures this out is Form 7206, especially if long-term-care premiums are in the mix.

This is one of the most powerful legal levers you have to shrink your tax bill and new freelancers almost never realize it counts.

When you put money into a self-employed retirement plan, that money is deductible. And the limits are way higher than a regular IRA. You've basically got two popular options for 2026:

• SEP-IRA: up to 25% of your compensation (roughly 20% of your net self-employment income if you're a sole proprietor), up to $72,000.

• Solo 401(k): you can put in up to $24,000 as an employee deferral, plus an employer contribution of about 20% of your net income — with extra catch-up room if you're 50 or older (and an even bigger catch-up if you're 60 to 63).

Sit with that for a second. You're not throwing the money away — you're moving it from "the IRS" to "future you." That's about as good as tax planning gets.

Let's clear the air on this one, because a myth has been scaring freelancers off it for years: claiming a home office does not automatically trigger an audit. It doesn't. Not when you genuinely qualify.

If you use a space in your home regularly and exclusively for work, you can deduct a portion of your home costs. You've got two ways to do it:

• Simplified method: $5 per square foot, up to 300 square feet — so a $1,500 max. Easy. It goes straight on Schedule C, no extra form.

• Regular method: you calculate the business-use percentage of your rent or mortgage interest, utilities, insurance, and repairs on Form 8829. It can be worth more than $1,500, but you'll need to keep records.

The words that matter are regularly and exclusively. Your kitchen table where you also eat cereal? Doesn't count. A dedicated corner or room that's only for work? That counts.

QBI stands for Qualified Business Income, and it lets you deduct up to 20% of your qualified business income before your income tax is even figured.

People skip this one for a funny reason: it's relatively new (it arrived in 2018) and it sounds too generous, so folks assume it can't be real. It's real. It was even made permanent under the OBBBA law. You claim it using Form 8995 (or 8995-A).

One thing to know: QBI knocks down your income tax only, it doesn't touch your self-employment tax. But 20% off your taxable business income is nothing to sneeze at.

You use your phone and internet for work. Some of that bill is a business expense and you're allowed to deduct that share.

The mistake people make is thinking that because the bill is mixed (part personal, part work), none of it counts. Not true. You just deduct the business-use percentage. So if 60% of your $100 phone bill is for work, that's $60 a month you can write off.

Just keep a reasonable basis for how you landed on that split, in case anyone asks.

Every time you drive for work — to a client, a job site, the post office, a supply run — those miles can count. (Your regular commute doesn't, sorry.)

Two ways to claim it:

• Standard mileage: 72.5 cents per mile for 2026 (up from 70¢ in 2025), multiplied by your business miles.

• Actual expenses: the business-use percentage of your gas, insurance, repairs, and depreciation.

Why do freelancers miss this? Because the little trips slip their mind, and those little trips add up. The key is a mileage log — date, miles, purpose. That simple record is what makes the deduction stick.

Here's one that surprises people: you can write off money you spent before your business officially opened its doors.

Market research, a logo, your website, legal and registration fees, your first batch of supplies, all of it can count. Folks assume expenses only start mattering once they're "officially" in business, so they forget everything that came before. You can generally deduct up to $5,000 of startup costs in your first year (the rest gets spread out, or "amortized," over 15 years).

Courses, certifications, books, workshops, conferences.Iif they maintain or improve the skills you use in your current business, they're deductible.

But here's the line that trips people up, so read it twice: education that improves your existing work counts. Education that qualifies you for a brand-new career does not.

An example makes it click. A freelance designer taking an advanced design course? Deductible. That same person going to law school to become a lawyer? Not deductible, that's a whole new trade.

Two sneaky ones to finish.

First, payment-processing fees. Every time PayPal, Stripe, or Square takes their cut, that's a business expense. People miss it because the fee is invisible, it gets skimmed off before the money even hits your account, so you never actually "see" it leave. But it's a real cost, and it's deductible.

Second, software subscriptions. Your design tools, accounting app, cloud storage, domain and hosting — the monthly stuff that keeps your business running. It feels personal because it's on your card every month, but these are ordinary business costs. Write them off.

If you're on a roll, here are a handful of extras worth checking:

• HSA contributions — deductible if you have a qualifying high-deductible health plan.

• Equipment — laptops, cameras, tools. Thanks to the OBBBA law, 100% first-year bonus depreciation is back for 2026, and Section 179 lets you expense qualifying gear up front (the 2026 limit is around $2.56M — far more than any solo freelancer will ever need). Reported on Form 4562.

• Business meals — generally 50% deductible when there's a real business purpose, like a client lunch or a meal while traveling.

• Business insurance — liability, professional, errors-and-omissions, and the like.

• Professional services — your accountant's and lawyer's fees for the business.

• Advertising and marketing — ads, business cards, promotional costs.

• Bank fees and loan interest — fees on your business account and interest on business borrowing.

So why do people miss all this?

Here's the honest answer, and it's not "they're bad with money."

The expenses get missed because they're scattered everywhere, a receipt in your email, a charge on your card statement, a subscription buried in an app. 

Nobody sits down and reconciles it all until April, and by then half of it is forgotten.

And it stings twice, remember? Because deductions are worth about 15.3% more to you than to an employee, every forgotten receipt is money taxed twice over.

There's a newer wrinkle too. With 1099 reporting thresholds raised to $2,000 for 2026, the IRS automatically sees less of your activity. That cuts both ways — less of your income gets reported for you, but there's also no third-party paper trail backing up your expenses. Which means your own records become the proof.

The real difference between the freelancer who claims all ten of these and the one who misses half isn't tax knowledge. It's whether their expenses got captured the moment they happened, instead of hunted down in a panic in April.

That's the whole game. Capture it when it happens, and come tax time, you're not leaving your own money on the table.
