What a “tax deduction” (write-off) means—simple example

A tax deduction (often called a “write-off”) is a business expense that can lower the income you pay taxes on.

Example (simplified):

• You made $5,000 from your side hustle.
• You spent $500 on legit business expenses.
• You may only be taxed on $4,500.

That’s why tracking deductible business expenses for a side hustle matters.

Before the list: one rule that keeps you safe

A good rule of thumb: an expense is usually deductible if it’s ordinary and necessary for your side hustle.

Plain English:

• Ordinary = common for what you do
• Necessary = helpful for running your side hustle

Also: if something is partly personal and partly business (like your phone), you typically deduct only the business portion.

The beginner list of side hustle tax deductions (2026)

Below are common side hustle tax deductions and side hustle write offs that apply to many people: gig workers, Etsy sellers, freelancers, content creators, and weekend service providers.

1) Home office deduction (if you qualify)

The home office deduction for a side hustle can apply if you use a specific area of your home regularly and exclusively for business.

Simple example:

• You use a spare bedroom corner only for editing videos, client calls, and admin.
• You don’t use that space as a guest room or storage.

What might be deductible:

• A portion of rent or mortgage interest
• Utilities (electric, water)
• Internet (business portion)

Beginner warning: If the space is “sometimes business, sometimes personal,” it may not qualify.

2) Car and mileage (huge for gig workers)

If you drive for your side hustle (deliveries, client visits, picking up supplies), mileage deduction for a side hustle is often one of the biggest.

What to track:

• Date
• Where you went
• Business purpose
• Miles driven

Simple example:

• You drive 12 miles to a client job and 12 miles back.
• That 24 miles may be deductible if it’s business-related.

Beginner warning:

• Commuting to a regular W-2 job usually isn’t deductible.
• You need a mileage log—guessing is risky.

3) Phone and internet (partial deductions)

The phone and internet deduction for a side hustle is common because most side hustles run on communication.

How it works in plain English: If you use your phone 30% for business and 70% personal, you generally deduct about 30% of eligible costs.

What might be deductible:

• A portion of your monthly phone bill
• A portion of your internet bill

Beginner warning: Don’t claim 100% unless it’s truly a business-only line.

4) Supplies, tools, and equipment

These are classic tax write offs for a side hustle.

Examples by hustle:

• Online seller: shipping tape, labels, mailers
• Fitness content creator: tripod, lighting
• Handyman: drill bits, safety gear
• Tutor: whiteboard, markers

5) Software and subscriptions

If you pay for tools that help you run your side hustle, those may count as deductible business expenses for a side hustle.

Examples:

• Website hosting
• Email marketing software
• Design tools
• Accounting software

6) Advertising and marketing

Marketing costs are often deductible because they help you get customers.

Examples:

• Business cards
• Paid ads
• Canva templates
• A domain name

7) Education and training (courses, books, workshops)

If education helps you improve skills for your current side hustle, it may be deductible.

Examples:

• A course on video editing for your content business
• A bookkeeping class for your freelance work
• Books directly related to your niche

Beginner warning: Education that qualifies you for a totally new career can be treated differently.

8) Business meals (keep it simple)

Business meals deduction can apply when the meal is directly related to business (like meeting a client or discussing a project).

Simple example:

• You meet a client to talk about a paid project.
• You keep the receipt and note who you met and what you discussed.

Beginner warning:

• Eating alone “because you’re working” usually doesn’t count.
• Keep documentation.

9) Travel (only when it’s truly business)

If you travel for your side hustle—conference, client work, or a business event—some costs may be deductible.

Examples:

• Flights
• Hotels
• Transportation (rideshare, rental car)

Beginner warning: Mixing vacation and business gets complicated fast. Track what’s truly business.

10) Platform fees and payment processing fees

If you sell on platforms or take payments online, fees can add up—and may be deductible.

Examples:

• Etsy fees
• PayPal processing fees
• Stripe fees
• Marketplace listing fees

11) Banking fees and interest (business-related)

If you have a business bank account or business credit card, certain fees may be deductible.

Beginner tip: Consider a separate account for your side hustle to keep records clean.

What to track (so you’re not guessing)

If you do nothing else, do this:

• Save receipts (photo is fine)
• Keep a mileage log if you drive
• Track income deposits
• Track business vs personal percentages (phone/internet)

Beginner-friendly system:

• One folder in your phone for receipts
• One spreadsheet with categories (mileage, supplies, software, marketing)

Common beginner mistakes (and how to avoid them)

• Mixing personal and business spending: separate accounts help.
• No proof: deductions without receipts/logs are risky.
• Claiming 100% business use when it’s not true.
• Forgetting small recurring expenses (subscriptions, fees).

Final reminder (keep it simple)

You don’t need to be “good at taxes” to handle this. You just need a basic system and the discipline to track expenses weekly.
