Payment Processors & Taxes: What Law Firms Need to Know

As a law firm owner in the DMV, you’ve probably noticed that Stripe, Square, and PayPal make accepting client payments incredibly convenient. Whether you’re collecting retainers, flat fees, or hourly billings online, these payment processors have become standard tools. But here’s what many attorneys overlook: these platforms have real tax implications that can affect your bottom line come April.

Let’s break down what you need to understand about using Stripe, Square, or PayPal for your law practice—and how to stay compliant with IRS reporting requirements.

The 1099-K Reporting Requirement

The biggest tax consideration is the Form 1099-K. Payment processors are required to report your transactions to the IRS if you hit certain thresholds. The exact threshold has been a moving target in recent years, but as of 2024, payment processors must issue a 1099-K if your payment volume exceeds $5,000 in a calendar year.

Here’s what matters for your law firm:

• Stripe, Square, and PayPal will file a 1099-K with the IRS listing your gross transaction volume
• You must report this income on your tax return, even if the amount seems high (it includes refunds and adjustments that don’t represent final revenue)
• The IRS matches these filings against your reported income, so discrepancies raise red flags
• If you’re an LLC, S-corp, or sole proprietor, the processor may issue the form to your business or personal name depending on how you set up the account

Many law firms are surprised to see their 1099-K total exceed their actual net revenue because processors report gross payments, not adjustments, refunds, or trust account pass-throughs.

Trust Accounts and IOLTA Compliance

One unique consideration for law practices: if you’re accepting client funds into an IOLTA (Interest on Lawyer Trust Accounts) account, you need to be careful about how those payments flow through your payment processor.

In DC, Maryland, and Virginia, bar associations strictly govern trust account deposits and withdrawals. If you’re using Stripe or Square to accept retainers or advance payments that belong in trust, the funds should route directly to your IOLTA account—not your operating account. This is critical for compliance and ethical practice.

Here’s the tax angle: trust account deposits are not your income. They’re client funds you’re holding. If those funds flow through your operating account first, your 1099-K may overstate your actual earned revenue, creating reconciliation headaches come tax time.

Comparing the Three Processors

While the tax treatment is similar across platforms, there are some operational differences worth noting:

• Stripe: Offers customizable integrations and robust reporting. Good for firms using practice management software (Clio, LawLics, etc.). Typically reports to the IRS in the name on your Stripe Account.
• Square: User-friendly and straightforward. Best for smaller practices or those accepting in-person payments. Clear dashboard for tracking transactions.
• PayPal: Long-standing and recognizable, but slightly higher fees. Popular with solo practitioners. May report under your PayPal account name, which can differ from your legal entity name.

From a tax and bookkeeping perspective, all three require the same level of reconciliation and reporting diligence.

Tax Deductions and Processor Fees

Here’s a silver lining: payment processing fees are fully deductible business expenses. Every dollar Stripe, Square, or PayPal takes as a fee reduces your taxable income.

This is where consistent bookkeeping matters. You want these fees properly categorized and tracked so you don’t miss the deduction. It’s easy to overlook if you’re not reviewing your processor statements regularly.

For firms in DC, Maryland, and Virginia, remember that local tax calculations (like DC’s BPOL tax for service businesses) often require you to report gross revenue minus certain deductions—and understanding your true revenue net of processor fees is essential.

Staying Compliant and Audit-Ready

Here’s what we recommend to law firm clients at Capital Accounting Group:

• Download and reconcile your payment processor statements monthly, not just at year-end
• Match processor deposits to your bank deposits—they should align, accounting for timing
• Separate trust account deposits from operating account income in your bookkeeping system
• Keep processor fee documentation to support deductions
• Reconcile your 1099-K against your actual reported income before filing your return

If there’s a mismatch between your 1099-K and your reported income, you’ll need to address it on your tax return with an explanation. The IRS notices discrepancies, and audits are more likely when they’re large.

Tax compliance for law firms involves more moving parts than many service businesses, especially when trust accounts and client funds are involved. Whether you’re using Stripe, Square, or PayPal, the key is staying organized and ensuring your bookkeeping reflects the true picture of your firm’s finances.
