Tax Write-Offs for Solo Attorney Practices: The Complete List

2026-08-21

A complete list of tax write-offs for solo attorneys, with realistic 2026 figures and practical steps to maximize deductions legally.

Running a solo law practice means every dollar counts. One of the most effective ways to keep more of your income is to take advantage of every tax write-off you’re legally entitled to. This guide covers the complete list of deductions available to solo attorneys in 2026, with realistic figures and practical steps you can take this week.

1. Home Office Deduction

If you use part of your home regularly and exclusively for your practice, you can deduct it. The simplified method gives you $5 per square foot, up to 300 square feet, for a maximum deduction of $1,500. The regular method allows you to deduct a percentage of your mortgage interest, rent, utilities, insurance, and repairs based on the square footage of your office. For most solo attorneys, the simplified method is easier and often more beneficial.

Practical step: Measure your office space and calculate both methods. Use the one that gives you the larger deduction. Keep a log of business use to support your claim.

2. Legal Research and Continuing Education

Subscriptions to legal research services like Westlaw or LexisNexis are fully deductible. Costs for continuing legal education (CLE) courses, including registration fees, travel, and lodging, are also deductible. In 2026, expect to pay $200-$500 per CLE course, and $100-$300 per month for research subscriptions.

Practical step: Review your credit card statements for the past year and identify all research and CLE expenses. Keep receipts and certificates of completion.

3. Office Supplies and Equipment

Office supplies like paper, pens, printer ink, and postage are deductible. Equipment such as computers, printers, and office furniture can be deducted under Section 179, allowing you to expense the full cost in the year of purchase. For 2026, the Section 179 limit is $1,220,000, so most solo attorneys can deduct the full cost of new equipment. Alternatively, you can depreciate over time.

Practical step: If you’re planning to buy new equipment, do it before December 31 to take the deduction this year. Keep all receipts.

4. Professional Fees and Dues

Bar association dues, malpractice insurance premiums, and professional liability insurance are all deductible. In 2026, bar dues range from $100-$500 per year, and malpractice insurance can cost $2,000-$10,000 annually depending on your practice area and state.

Practical step: Gather your annual statements for bar dues and insurance premiums. Ensure they are paid from your business account.

5. Marketing and Advertising

Costs for website hosting, domain names, online ads (Google Ads, Facebook Ads), print materials, and networking event fees are deductible. In 2026, website hosting costs $10-$50 per month, and online ads can range from $100-$1,000+ per month depending on your budget.

Practical step: Track all marketing expenses in a separate category. Use a dedicated credit card for business expenses to simplify tracking.

6. Travel and Meals

Business travel, including airfare, hotels, and rental cars, is deductible. Meals with clients or potential clients are 50% deductible. In 2026, a typical business meal costs $50-$150 per person. Keep detailed records of the business purpose and attendees.

Practical step: Use a mileage tracking app to log business miles. For meals, note the business purpose on the receipt.

7. Software and Technology

Legal practice management software, billing software, cloud storage, and other tech tools are deductible. In 2026, practice management software costs $50-$200 per month, and billing software is often $20-$100 per month.

Practical step: List all software subscriptions you use for your practice. Cancel any that you don’t use regularly, and keep the rest as deductions.

8. Retirement Plan Contributions

Contributions to a SEP IRA, Solo 401(k), or SIMPLE IRA are deductible. For 2026, the SEP IRA contribution limit is $69,000 (or 25% of compensation, whichever is less), and the Solo 401(k) limit is $69,000 plus a $7,500 catch-up if you’re 50 or older. These contributions reduce your taxable income dollar-for-dollar.

Practical step: If you haven’t set up a retirement plan, do so before December 31. Even a small contribution can save you thousands in taxes.

9. Health Insurance Premiums

If you’re self-employed, you can deduct health insurance premiums for yourself, your spouse, and dependents. This deduction is taken on your personal return, not your business return. In 2026, individual health insurance premiums average $400-$800 per month.

Practical step: Keep records of your premium payments. Ensure your policy is in your name or your business’s name.

10. Miscellaneous Deductions

Other deductions include bank fees, credit card processing fees, postage, and professional books. Also, if you hire contractors, their fees are deductible. In 2026, credit card processing fees are typically 2-3% of transactions.

Practical step: Review your bank statements for fees and categorize them as business expenses.

FAQ

Q: Can I deduct my home office if I also have an office outside the home? A: Yes, if you use the home office regularly and exclusively for business, you can deduct it even if you have another office. However, the home office must be your principal place of business or used for administrative tasks.

Q: What is the best way to track expenses? A: Use accounting software like QuickBooks or Xero, and link your business bank and credit card accounts. Categorize expenses weekly to avoid a year-end scramble.

Q: Are legal settlements I pay on behalf of clients deductible? A: Yes, if you pay a settlement as part of your business, it is deductible as a business expense. However, consult your accountant for specific situations.

Q: How long should I keep receipts? A: Keep receipts for at least three years, but for assets like equipment, keep them for as long as you own the asset plus three years.

The bottom line

Maximizing your tax write-offs is a year-round effort. Start by implementing the practical steps above this week: track your expenses, set up a retirement plan, and review your subscriptions.
