No. Credit card processing fees cannot come out of client trust funds. This is a trust account violation, full stop. The money in an IOLTA or client trust account belongs to the client, and a processing fee is a cost of doing business for the firm. Deducting that fee from trust means you are using client funds to cover your own expense.

Here is what should happen. If a client pays a $5,000 retainer by credit card, exactly $5,000 must land in the trust account. The 2% to 3% processing fee gets charged to the firm’s operating account. The client’s funds remain whole, and the firm absorbs the cost of accepting the payment.

This is why legal-specific payment processors like LawPay, Headnote, and CosmoLex Payments exist. They are designed to split the transaction automatically. The full amount of the client payment goes to trust while the processing fee routes to your operating account. General-purpose processors like Square or standard Stripe integrations don’t handle this split correctly, which is why they create compliance problems for law firms.

If your firm has been running client trust payments through a general payment processor and the fees are being deducted before funds hit trust, you need to fix this immediately. The shortfall in your trust account is a compliance issue that state bar auditors look for specifically. Even small amounts add up over time and create discrepancies that are difficult to explain during an audit.

From a bookkeeping perspective, processing fees should be recorded as a business expense in your operating account. They are categorized separately from the trust transactions themselves. Professional services bookkeeping for law firms requires careful separation of trust and operating activity, and processing fees are one of the areas where mistakes happen most often.

Setting up your payment processing and accounting correctly from the start prevents trust accounting problems down the road. If you are unsure whether your current setup handles the fee split properly, it is worth having someone review your accounts.
