Texas has one of the largest freelance and independent contractor communities in the country, particularly in cities like Austin, Dallas, and Houston. If you're freelancing in Texas and dealing with slow-paying clients, here's what the law says about late fees and how to actually enforce them.

Texas Usury Law and Interest Rate Limits

Texas has usury laws that cap interest rates, but the limits are higher than you might expect — and they're largely a non-issue for standard freelance late fees.

For commercial transactions (business-to-business), Texas law allows parties to contract for any rate that doesn't exceed the "ceiling" set by the Texas Finance Code. For most commercial agreements, the ceiling is 18% annually — which happens to be exactly what most freelancers charge (1.5% per month).

In practice, if you're charging 1.5% per month (18% annually) on business invoices in Texas, you're well within legal limits. Some freelancers go up to 2% per month (24% annually) in their contracts — this may be enforceable depending on the client type, but staying at 18% is cleaner and less likely to be challenged.

Texas rule of thumb: 1.5% per month (18% annually) is the standard and legally straightforward rate for freelance invoices in Texas. Stick with this unless you have a specific reason to go higher.

Texas Prompt Payment Act

Texas has a Prompt Payment Act, but it primarily applies to government contracts and construction. For standard freelance work with private-sector clients, you're relying on your contract — which is why having one matters.

If you do any government contracting work in Texas, the Prompt Payment Act requires state agencies to pay within 30 days of receiving a correct invoice, with automatic interest penalties for late payment. This is actually one of the better protections available if you work with Texas state government clients.

Making Late Fees Stick in Texas

Texas courts enforce contracts. If you've got it in writing and you followed your own terms, you have a strong position. Here's what to include:

Texas does not require a specific written format for freelance contracts. An email exchange where both parties agree to terms can be binding — but a proper signed contract is always stronger.

Texas Small Claims Court

Texas Justice Courts handle small claims up to $20,000 — one of the higher limits in the country. For most freelance disputes, this means you can pursue the full amount without a lawyer.

The process is relatively simple:

Texas courts can award the original debt plus interest, court costs, and in some cases attorney's fees if your contract includes a fee-shifting clause.

When to Send a Demand Letter

Before filing in small claims, send a formal demand letter. In Texas, this isn't legally required for most disputes, but it often works — clients who ignored your emails may respond when they see certified mail with a deadline and a mention of legal action.

Keep your demand letter factual: state the amount owed, the original due date, the accumulated late fees, and a deadline to pay (typically 10–14 days) before you file a claim.

The Bottom Line for Texas Freelancers

Texas is a contract-friendly state. If you have a solid written agreement with clear payment terms, you're in a good position to enforce late fees. The combination of clear contracts, professional follow-up, and Texas Small Claims Court (with its generous $20,000 limit) gives you real leverage against clients who don't pay.

Set your terms before you start work, put everything in writing, and don't wait too long to escalate when payments go overdue.
