Discover overlooked tax deductions for solo attorneys, from home office to CLE costs, and save thousands legally. Practical tips for 2026.

Running a solo law practice means every dollar counts, and tax deductions are a direct way to keep more of what you earn. Many solo attorneys miss out on legitimate deductions simply because they don’t track them or assume they don’t qualify. This guide covers the most commonly overlooked deductions for solo practitioners, with realistic figures and steps you can take this week to reduce your tax bill.

Home Office Deduction

If you use part of your home regularly and exclusively for your law practice, you can deduct home office expenses. The IRS offers two methods: the simplified method ($5 per square foot, up to 300 square feet, max $1,500) or the regular method (actual expenses like mortgage interest, utilities, and repairs, prorated by square footage). For a typical solo attorney, the regular method often yields a larger deduction, especially if you have a dedicated office. For example, if your home office is 200 square feet and your home is 2,000 square feet, you can deduct 10% of your rent or mortgage interest, utilities, and internet. That could be $200-$400 per month in deductions, depending on your costs. To claim this, measure your office space, calculate the percentage, and keep a log of business use. You must use the space exclusively for work, so no guest beds or kids’ toys.

CLE is mandatory for attorneys, but many don’t realize the full scope of deductible expenses. You can deduct registration fees, travel, lodging, and 50% of meals while attending CLE courses. For example, a two-day CLE conference in another city might cost $500-$1,500 in registration, plus $300-$600 for a hotel, and $100-$200 for meals. That’s a total of $900-$2,300 you can deduct. Even online CLE courses are deductible, including the subscription fees for services like West LegalEdcenter or Lawline, which run $200-$500 per year. Keep all receipts and a log of the business purpose. Also, if you travel to a CLE, you can deduct airfare and ground transportation, but be sure to keep the agenda to prove it was business-related.

Professional Liability Insurance

Malpractice insurance is a must for solo attorneys, and the premiums are fully deductible. Depending on your practice area and state, annual premiums range from $1,500 to $5,000 or more. For example, a solo family law attorney in Texas might pay $2,500 per year, while a securities lawyer in New York could pay $8,000. Deduct the full amount as a business expense. If you pay monthly, that’s $125-$400 per month. Keep your policy documents and payment records. Also, if you pay for tail coverage when you close a practice, that’s deductible too, but only if it’s for business purposes.

Subscriptions to legal research tools like Westlaw, LexisNexis, or Fastcase are deductible. These can be significant costs, often $200-$600 per month for solo attorneys, depending on the plan. For example, a solo practitioner might pay $3,000-$7,000 per year for Westlaw access. That’s a substantial deduction. Also, if you use free or low-cost tools like Google Scholar, you can’t deduct the time, but any paid subscriptions are deductible. Keep invoices and note the business use. If you use a subscription for both personal and business, you must allocate the percentage, but for legal research, it’s almost always 100% business.

Office Supplies and Technology

Many solo attorneys forget to deduct everyday office supplies and technology. This includes pens, paper, printer ink, postage, and software. For example, a solo attorney might spend $50-$150 per month on supplies, which adds up to $600-$1,800 per year. Also, technology like laptops, monitors, and printers are deductible, either as a Section 179 expense (up to $1,050,000 in 2026) or as a depreciation deduction. If you buy a $1,500 laptop, you can deduct the full amount in the year of purchase using Section 179. Software subscriptions like Clio, QuickBooks, or Microsoft 365 are also deductible, typically $50-$200 per month. Track every purchase, no matter how small, and use a dedicated business credit card to simplify record-keeping.

Marketing and Advertising

Solo attorneys often spend on marketing but miss some deductible items. This includes website costs, SEO services, pay-per-click ads, and even business cards. For example, a solo attorney might spend $500-$2,000 per month on marketing, including a website maintenance fee of $50-$100 per month, Google Ads at $300-$1,000 per month, and networking event fees. All of these are deductible. Also, if you sponsor a local event or host a seminar, those costs are deductible. Keep receipts and track the business purpose. If you use social media, the cost of a social media manager (if you hire one) is deductible, but the time you spend is not.

Travel and Mileage

If you travel for client meetings, court appearances, or depositions, you can deduct travel expenses. This includes airfare, hotel, and 50% of meals, but the most common is mileage. In 2026, the standard mileage rate is 67 cents per mile (projected, as it was 65.5 cents in 2023 and 67 in 2024, and likely to be around 67-68 cents). For example, if you drive 10,000 miles for business per year, that’s a $6,700 deduction. To claim this, keep a mileage log with date, miles, and purpose. You can use apps like MileIQ or TripLog to track automatically. Also, if you use your car for business, you can deduct parking and tolls. Don’t forget to deduct the cost of a rental car if you travel for a deposition.

Retirement Plan Contributions

Solo attorneys can deduct contributions to retirement plans, which is a powerful way to reduce taxable income. Options include a SEP IRA, Solo 401(k), or SIMPLE IRA. For 2026, the contribution limits are: SEP IRA up to 25% of net self-employment income, max $69,000 (projected); Solo 401(k) allows employee deferrals of $23,500 (projected) plus employer contributions, total up to $69,000 (projected). For example, if your net income is $150,000, you could contribute $37,500 to a SEP IRA and deduct that amount. To set up a plan, contact a financial institution like Fidelity or Vanguard, and you can open one in a day. The deadline to set up a SEP IRA is the tax filing deadline (usually April 15), but a Solo 401(k) must be established by December 31. This is one of the best deductions because it saves you taxes now and builds your retirement.

Professional Dues and Subscriptions

Membership dues to bar associations and professional organizations are deductible. This includes your state bar dues (often $200-$500 per year), local bar association fees, and memberships in organizations like the American Bar Association ($150-$300 per year). Also, subscriptions to legal journals and magazines are deductible. For example, a subscription to the ABA Journal costs $85 per year, and a state bar journal might be $50. Keep your membership cards and receipts. If you join a legal networking group like a local trial lawyers association, those dues are deductible too.

FAQ

Can I deduct home internet if I work from home?

Yes, but only the portion used for business. If you have a home office, you can deduct a percentage of your internet bill based on the square footage of your office. For example, if your office is 10% of your home, you can deduct 10% of your internet bill. If you don’t have a home office, you can deduct the actual business use, but you need to track it.

What is the best way to track my mileage?

Use a mileage tracking app like MileIQ or TripLog. They automatically log your trips using GPS, and you can categorize them as business or personal. At the end of the year, you can generate a report for your tax preparer. Alternatively, keep a written log in your car, but it’s easy to forget.

Yes, legal fees for your business, such as reviewing a contract or defending a malpractice claim, are deductible as ordinary business expenses. However, legal fees for personal matters are not deductible.

Can I deduct the cost of a new suit for court?

No, the IRS considers clothing deductible only if it’s not suitable for everyday wear. Since a suit can be worn outside of court, it’s not deductible. However, if you have a uniform with a logo, that would be deductible.

The bottom line

Solo attorneys have many opportunities to reduce their tax burden, but it requires careful tracking and knowledge of the rules. Start by reviewing your expenses from the past year and see if you missed any of these deductions. Implement a system to track mileage, receipts, and business use of your home. Consider setting up a retirement plan before the deadline. If you’re unsure, consult a CPA who specializes in solo professionals. The money you save can be reinvested in your practice or your future. Take action this week: open a mileage log, review your subscriptions, and calculate your home office percentage. Your tax bill will thank you.
