Looking at your self-employment income and feeling that tax anxiety creeping in? Trust me, I’ve been there! As someone who transformed from a preschool teacher to a self-employed financial educator, I know firsthand how overwhelming self employed tax deductions can be. But here’s the tea: understanding your tax write-offs isn’t just about following rules—it’s about keeping more of your hard-earned money where it belongs: in YOUR pocket!
Here’s something that keeps me up at night: so many self-employed individuals miss out on potential tax deductions simply because they don’t know what they can claim. That’s literally leaving money on the table! Whether you’re a seasoned entrepreneur or just started your side hustle, I’m about to show you exactly how to maximize your tax savings in 2025.
In this guide, you’ll learn all the tax deductions you can claim, from home office and vehicle expenses to retirement contributions and professional development costs. Plus, I’ll share my personal tips on how to track and organize everything to make tax time a breeze!
Ready to stop leaving money on the table? Let’s dive in and make those write-offs work for you! ?
Key Takeaways
- Track every business expense like it’s your job (because it is!) using tools like YNAB‘s business expense tracking feature to never miss a deductible penny
- Claim your home office deduction correctly—it’s one of the most valuable yet underutilized write-offs for home businesses
- Protect your business legacy and minimize estate taxes with proper planning (Trust & Will can help you set this up right)
- Stay organized with digital receipt management to make tax time less stressful
- Remember quarterly estimated tax payments to avoid surprises and penalties
- Keep business and personal expenses separate to make tax filing easier and audit-proof
What Counts as a Business Expense? Breaking Down the Basics
Listen up, because this is where many self-employed folks get tripped up! The IRS has a pretty straightforward rule: business expenses must be both “ordinary and necessary” for your business. But what does that actually mean?
Ordinary Expenses
These are the common costs in your line of work. If you’re a photographer, camera equipment is ordinary. If you’re a virtual assistant, your laptop and software subscriptions are ordinary. You get the picture!
Necessary Expenses
These are expenses that help you run your business effectively. They don’t have to be indispensable, but they should make sense for your business operations.
? Pro Tip: One of the smartest moves I made in my business was using YNAB to track all my expenses. Their business expense tracking features make it super easy to categorize everything as it happens, so you’re not scrambling come tax time. Plus, you can create specific business categories that align with IRS deduction categories. (Yes, this is an affiliate link, but I genuinely use and love YNAB for my own business!)
The Ultimate List of Self Employed Tax Deductions for 2025
1. Home Office Deduction
This is the big one! If you use part of your home regularly and exclusively for business, you can deduct expenses for that portion of your home.
Two ways to calculate:
Simplified Method
- Calculate your deduction at $5 per square foot of your home office space
- Maximum allowed space is 300 square feet
- Maximum deduction is $1,500 (300 sq ft × $5)
- Perfect if you want a hassle-free calculation
- No need to track actual expenses
- Can’t deduct depreciation or carry over unused expenses
- Must still use the space exclusively for business
Regular Method
- Calculate the percentage of your home used for business
- Example: If your home office is 200 sq ft and your home is 2,000 sq ft, your business percentage is 10%
- Deduct that percentage of:
- Mortgage interest or rent payments
- Property taxes
- Homeowners insurance
- Utilities (electricity, gas, water)
- Internet and phone service
- Home repairs and maintenance
- Home depreciation
- Security system
- Can result in larger deductions for larger homes or areas with high housing costs
- Must keep detailed records of all expenses
- Can carry over unused expenses to future years
- Requires more documentation but potentially higher savings
? Pro Tip: Run the numbers both ways before deciding! While the simplified method is easier, the regular method might save you more money if you live in an area with high housing costs or if your home office takes up a significant portion of your home.
Common Home Office Mistakes to Avoid
- Using your space for both business and personal activities
- Failing to document your home office measurements
- Not taking photos of your home office setup (great for documentation!)
- Forgetting to recapture depreciation when you sell your home
2. Vehicle Expenses
Got a car you use for business? You’ve got options:
Standard Mileage Rate
- Set by the IRS annually – Current 2025 rate is 67.5 cents per mile for business use
- Simply multiply your business miles by the rate
- Example: 5,000 business miles × $0.675 = $3,375 deduction
- Must track:
- Date of each trip
- Business purpose
- Starting and ending mileage
- Total miles driven
- Benefits:
- Easier to calculate
- Great for high-mileage drivers
- No need to track actual car expenses
- Can still deduct business parking and tolls separately
- Limitations:
- Must use this method in the first year you use the car for business
- Can’t use for more than 5 vehicles at once
- Can’t use if you’ve claimed accelerated depreciation
Actual Expenses Method
- Track all vehicle-related expenses and multiply by business-use percentage
- Deductible expenses include:
- Gas and oil
- Maintenance and repairs
- Tires
- Insurance premiums
- Vehicle registration fees
- Car loan interest
- Lease payments
- Depreciation
- Garage rent
- Car washes
- Calculate business-use percentage:
- Example: If you drive 20,000 total miles and 12,000 are for business, your business use is 60%
- Then multiply total car expenses by this percentage
- Benefits:
- Better for newer or luxury vehicles
- Could result in larger deduction if car expenses are high
- Good for low-mileage, high-expense situations
- Must keep:
- All receipts and records
- Detailed mileage log
- Documentation of business versus personal use
? Pro Tip: Once you choose the actual expenses method, you can’t switch back to standard mileage rate for that vehicle. Consider your long-term plans before deciding which method to use!
Maximizing Your Vehicle Deductions
- Keep a detailed mileage log (there are great apps for this!)
- Document all maintenance and repair costs
- Save those gas receipts
- Track parking fees and tolls for business trips
- Don’t forget about car loan interest and depreciation

My Lisa Rule: I have 4 sisters and Lisa is the baby (well she’s not a baby anymore). Of all of my sisters, I’m the most protective over her. Before I share any product or service with you, it must pass my Lisa Rule.
What’s the Lisa Rule?
If I would not advise Lisa to use a product or service, I won’t advise you to. YOU are my Lisa. I feel protective over you and your financial journey. YNAB and Trust & Will pass my Lisa Rule. Yes, I am an affiliate of these companies, and I earn a commission off of referrals, but I would not recommend a product or service that I didn’t believe was helpful and useful.
