Most legal expenses are not tax deductible, but some are

The IRS allows you to deduct legal fees only in specific situations — mainly when the legal work produces income or protects income-producing property. Personal legal matters like divorce, custody disputes, or buying a home are never deductible, even if the bills are large. The rule is straightforward: if the legal work is tied to your business or investments, you may deduct it; if it's tied to your personal life, you cannot.

The distinction matters because the IRS looks at what the legal work accomplished, not how much it cost or how necessary it felt. A lawyer's bill for the same hourly rate can be fully deductible in one situation and completely non-deductible in another, depending solely on the purpose of the work.

Key Takeaways

  • Legal fees for business matters — contract disputes, tax information, incorporation, employment issues — are deductible as business expenses on Schedule C or your business tax return.
  • Legal fees for investment-related work, such as reviewing rental property documents or defending against a lawsuit over securities, may be deductible as miscellaneous itemized deductions, subject to the 2% threshold.
  • Legal fees for personal matters — divorce, child custody, home purchase, estate planning, personal injury claims — are never deductible, regardless of the amount.
  • If a single legal matter involves both deductible and non-deductible work, you must allocate the bill between the two and deduct only the business or investment portion.
  • You need the lawyer's invoice showing what work was performed to substantiate any deduction you claim.

Legal expenses tied to your business or self-employment

If you are self-employed or own a business, legal fees for work directly related to that business are deductible. This includes fees for drafting contracts, reviewing client agreements, defending against a business lawsuit, handling employment disputes, incorporating your business, or obtaining a business license. You deduct these on Schedule C (Profit or Loss from Business) if you are a sole proprietor, or on your business entity's tax return if you operate as an S-corp, C-corp, or partnership.

The work must be tied to the business itself, not to your personal finances. For example, a lawyer's fee for defending your business against a negligence claim is deductible; a fee for defending you personally in an unrelated lawsuit is not. Similarly, legal fees to set up a business structure are deductible, but legal fees to set up a personal will or trust are not.

Keep the invoice from your lawyer that describes the work performed. The IRS may ask you to show what the legal work was for, and a vague bill labeled "legal services" is harder to defend than one that says "contract review for client agreement" or "representation in employment dispute."

Legal expenses for investment property and securities

Legal fees related to income-producing property or investments may be deductible, though the rules are more limited than for business expenses. If you own rental property and pay a lawyer to review a lease, defend against a tenant lawsuit, or handle a property dispute, that fee may be deductible. Similarly, if you pay a lawyer to review securities documents, defend against a lawsuit over an investment, or handle a dispute with a broker, that fee may be deductible.

These deductions are claimed as miscellaneous itemized deductions on Schedule A, and they are subject to a 2% threshold — meaning you can only deduct the amount that exceeds 2% of your adjusted gross income (AGI). For example, if your AGI is $100,000, you can only deduct investment-related legal fees above $2,000. This threshold makes small deductions worthless for most people.

Legal fees for buying or selling investment property are treated differently. Fees paid to acquire property are added to the property's cost basis rather than deducted as an expense. Fees paid to sell property reduce your proceeds and lower your capital gain, but they are not deducted as a separate line item.

Legal expenses you cannot deduct

Personal legal matters are never deductible, no matter the cost. Divorce and separation fees, including attorney time for negotiating support or custody, are not deductible. Child custody disputes, adoption proceedings, and guardianship matters are not deductible. Legal fees for buying a home, refinancing a mortgage, or handling a personal injury claim are not deductible. Fees for writing a personal will, trust, or power of attorney are not deductible.

The IRS considers these matters personal in nature, even though they may have financial consequences. The fact that a divorce settlement includes property division or alimony does not make the divorce lawyer's fees deductible. The fact that a personal injury lawsuit results in a large settlement does not make the personal injury lawyer's fees deductible.

One exception exists for a narrow situation: if part of a divorce involves a dispute over business assets or business valuation, the portion of legal fees attributable to that business dispute may be deductible. However, the fees must be clearly separated on the invoice, and only the business-related portion qualifies.

Allocating fees when legal work covers multiple purposes

Sometimes a single legal matter involves both deductible and non-deductible work. For example, a divorce that includes a dispute over a business you own may require the lawyer to handle both personal divorce issues and business valuation. In this case, you must allocate the bill between the two purposes and deduct only the business portion.

The allocation must be reasonable and documented. Ask your lawyer to itemize the invoice by the type of work performed — hours spent on business valuation, hours spent on custody negotiation, and so on. If the invoice does not separate the work, you can request an amended invoice that does. Without a clear allocation, the IRS will likely disallow the entire deduction.

The same principle applies to any legal matter that touches both business and personal concerns. If you pay a lawyer to handle a contract dispute and also to review a personal document, the invoice should show the hours spent on each task so you can deduct only the contract dispute portion.

Tax information and tax-related legal fees

Legal fees paid for tax information or tax-related work are deductible, but not as a business expense. Instead, they are deducted as a miscellaneous itemized deduction on Schedule A, subject to the same 2% threshold that applies to investment-related legal fees. This includes fees for a lawyer to represent you in an IRS audit, to handle a tax dispute, or to advise you on tax consequences of a business transaction.

The distinction is important: if a lawyer advises you on a business contract and also advises you on the tax consequences of that contract, the business information portion is deductible as a business expense, but the tax information portion is deductible only as a miscellaneous itemized deduction. Again, the invoice should separate the two so you can allocate correctly.

Tax preparation fees paid to a CPA or tax preparer are also deductible as miscellaneous itemized deductions, subject to the 2% threshold. However, if the tax work is related to a business you own, some or all of it may be deductible as a business expense instead, which is more valuable because it is not subject to the threshold.

Documentation and record-keeping

To support any legal expense deduction, keep the lawyer's invoice or bill that describes the work performed. A receipt that straightforward says "legal services" is not enough. The invoice should state what the work was for — for example, "contract review for business agreement," "representation in employment dispute," or "tax information regarding business structure."

If you pay a lawyer a retainer or flat fee, ask for an itemized breakdown of how the money was spent. If the lawyer bills by the hour, the invoice should show the hours spent on each task or matter. This documentation is essential if the IRS questions your deduction.

Keep these records for at least three years from the date you file your tax return. If the IRS audits you, the first thing it will ask for is proof of the expense and documentation of what the work was for.

Frequently Asked Questions

Can I deduct legal fees for a divorce that involves a business?

Only the portion of fees related to the business dispute is deductible. Fees for negotiating custody, support, or personal property division are not deductible. Your lawyer must itemize the invoice to show which hours were spent on business matters and which were spent on personal matters. Without a clear allocation, the IRS will disallow the entire deduction.

Are legal fees for buying a rental property deductible?

No, legal fees paid to acquire property are added to the property's cost basis, not deducted as an expense. This means they reduce your taxable gain when you eventually sell the property, but they are not deducted in the year you pay them. Fees for selling the property reduce your proceeds and lower your capital gain in the same way.

What if my lawyer's invoice doesn't say what the work was for?

Request an amended or detailed invoice from your lawyer that describes the work performed. If the lawyer cannot or will not provide this, you may not be able to substantiate the deduction. The IRS requires documentation showing what legal work was performed and why it qualifies as deductible.

Are legal fees for a personal injury lawsuit deductible?

No, legal fees for a personal injury claim are not deductible, even if you win a large settlement. The IRS treats personal injury matters as personal, not business or investment-related. However, if the lawsuit involves a business asset or business dispute, the business-related portion may be deductible if clearly separated on the invoice.

Can I deduct legal fees for estate planning or writing a will?

No, legal fees for writing a will, trust, power of attorney, or other estate planning documents are not deductible. These are considered personal matters. However, if the estate planning work involves a business you own and addresses business succession, the business-related portion may be deductible if the invoice separates it from the personal estate planning work.
