Most legal expenses are not tax deductible, but some are
The IRS allows you to deduct legal fees only when the money goes toward producing or protecting income that you report on your tax return. A lawyer's bill for your divorce, a DUI defense, or a personal injury case does not may have access to — those are personal matters. But legal work tied directly to your business, rental property, or investment income can be deductible.
The rule is straightforward in theory but messy in practice. A single legal bill might cover both deductible and non-deductible work. Your lawyer's invoice matters less than what the work actually was. The IRS looks at the nature of the legal problem, not the category of law the attorney practices.
Key Takeaways
- Legal fees for business matters, rental property disputes, and investment advice are usually deductible as business expenses.
- Legal fees for personal matters — divorce, criminal defense, personal injury — are never deductible, even if they are large.
- If one legal bill covers both business and personal work, you can deduct only the business portion if your lawyer itemizes the hours.
- You deduct business legal fees on Schedule C (self-employed), Schedule E (rental property), or as a business expense on your corporate return.
- Keep the lawyer's invoice and a description of what the legal work was for, because the IRS will ask if you claim the deduction.
Legal fees that are deductible
If you own a business or are self-employed, legal fees for contracts, employment disputes, business formation, or trademark protection are deductible. This includes work by a lawyer, paralegal, or legal document service. The work must relate to your business income.
If you own rental property, legal fees to evict a tenant, enforce a lease, or defend against a tenant lawsuit are deductible. Fees to purchase the property itself are not — those are capitalized and depreciated over time. Fees to resolve a boundary dispute with a neighbor or to challenge a property tax assessment are also deductible.
Legal fees for investment advice — such as reviewing a partnership agreement before you invest, or defending against an IRS audit of your investment income — are deductible. Fees to resolve a dispute with a broker or to recover investment losses may also be deductible if the dispute is about income-producing property.
Legal fees that are not deductible
Divorce and family law fees are never deductible, even if the divorce involves disputes over business assets or alimony. The IRS treats divorce as a personal matter. A narrow exception exists: if your lawyer's bill includes work on tax issues in the divorce (such as dividing a retirement account), you may be able to deduct only that portion. This requires the lawyer to separate the tax work from the family law work on the invoice.
Criminal defense fees, including DUI, drug charges, or any felony or misdemeanor, are not deductible. The IRS does not allow deductions for legal work to defend against criminal charges, even if you are found not guilty.
Personal injury lawsuits, including car accidents, medical malpractice, and slip-and-fall cases, are not deductible. The money you recover is usually not taxable income, so the fees to recover it are not deductible either. The one exception: if you recover damages for lost business income (not personal injury), the portion of the fee tied to that recovery may be deductible.
Fees for wills, trusts, and estate planning are generally not deductible. An exception exists if the trust or estate holds business assets or rental property and the legal work relates to managing that income-producing property.
How to handle a bill that covers both business and personal work
Many legal matters have both a business and personal side. A divorce involving a business you own, a lawsuit that touches on both personal and rental property issues, or a contract dispute that also involves personal liability can all result in a mixed bill.
Ask your lawyer to itemize the invoice by the type of work performed and the hours spent on each. For example: "4 hours on business valuation for divorce settlement" and "6 hours on custody and support issues." You can deduct only the hours tied to business or income-producing work.
If your lawyer refuses to itemize or cannot separate the work, you cannot deduct any of it. The IRS will not allow you to estimate or allocate the deductible portion yourself. Keep the invoice and any written explanation from your lawyer about what work was done.
Where to report deductible legal fees
If you are self-employed or own a sole proprietorship, report deductible legal fees on Schedule C (Form 1040), under "Legal and professional services." If you operate as an S-corporation or C-corporation, report them on your corporate tax return as a business expense.
If the legal fees relate to rental property, report them on Schedule E (Form 1040), under "Rental real estate, royalties, partnerships, S corporations, trusts, etc." Fees for each property should be listed separately if you own multiple rental properties.
If the legal fees relate to investment income (such as fees to defend against an audit of investment gains), report them on Schedule A as a miscellaneous deduction, subject to the 2% floor. This means you can deduct only the amount that exceeds 2% of your adjusted gross income. Many taxpayers do not itemize, so this deduction may not help you.
Documentation the IRS expects to see
Keep the lawyer's invoice or bill. It should show the date of the work, a description of what was done, and the amount charged. If the invoice is vague — for example, "legal services" with no detail — write a note on your copy explaining what the work was for and why it is deductible.
If the bill covers both deductible and non-deductible work, keep the itemized version that breaks out the hours by type of work. If your lawyer provided a written explanation of what portion of the bill is deductible, keep that too.
You do not need to attach these documents to your tax return, but keep them in your records for at least three years. If the IRS asks about the deduction, you will need to show that the legal work was directly tied to producing or protecting your business or investment income.
Frequently Asked Questions
Can I deduct legal fees for a lawsuit where I am suing someone?
Only if the lawsuit is about income-producing property or a business matter. Fees to sue for personal injury, breach of contract in a personal matter, or property damage are not deductible. Fees to defend a business contract dispute or to recover rental income are deductible.
What if I used a legal document service instead of a lawyer?
The same rules apply. Fees to a legal document service, paralegal, or online legal platform are deductible if the work is for business or rental property purposes. Keep the invoice and a description of what the service provided.
Can I deduct legal fees to set up an LLC or corporation?
No. Fees to form a business entity are capitalized, meaning you deduct them over several years, not all in one year. Fees for ongoing legal work after the business is formed — such as contract review or employment disputes — are deductible in the year you pay them.
What if my lawyer bill includes time spent on tax issues?
Tax-related legal work is deductible if it is tied to your business or investment income. For example, fees to a lawyer for tax advice on a business structure or to defend a business-related IRS audit are deductible. Fees for personal tax return preparation are not. Ask your lawyer to itemize the tax work separately from other work on the bill.
Do I need to itemize deductions to claim legal fees?
Not if the fees are business expenses reported on Schedule C or Schedule E. Those are deducted whether you itemize or take the standard deduction. If the fees are investment-related and reported on Schedule A, you must itemize to claim them, and they are subject to the 2% floor.
