Maryland freelancers face a shorter deadline than almost anywhere else in the country to sue over an unpaid invoice — just 3 years, versus 5 or 6 years in most neighboring states. Here's what Maryland freelancers need to know about late fees, from the legal interest rate to collecting through the District Court.

Maryland's 6% Legal Rate — and a Short Clock to Collect
Maryland's constitution fixes the legal rate of interest at 6% per year unless the General Assembly provides otherwise (Md. Const. Art. III, § 57; Com. Law § 12-102). That's the rate that applies by default when a contract doesn't specify its own — most Maryland freelancers instead write 1.5% per month (18% annually) directly into their contract and invoices, which courts treat as the agreed rate rather than the statutory fallback, as long as it's disclosed in writing and reasonable.
The bigger issue for Maryland freelancers isn't the rate — it's the clock. Maryland's general statute of limitations is just 3 years for nearly all civil claims, including both written and oral contracts (Md. Cts. & Jud. Proc. § 5-101). That's shorter than the 5–6 year windows common in most other states, so a Maryland invoice that sits unpaid for a couple of years is closer to being time-barred than freelancers typically expect.
How Maryland Compares to Nearby States

| State | Default rate | Small claims limit |
|---|---|---|
| Maryland | 6%/year | $5,000 |
| Virginia | 6%/year | $5,000 |
| Pennsylvania | 6%/year | $12,000 |
Maryland and Virginia share both the same 6% default rate and the same $5,000 small claims cap, so a freelancer working across the DMV area sees no real difference in either number. Pennsylvania uses the same 6% default rate but allows small claims up to $12,000 — more than double Maryland's ceiling — which matters if you take on larger Pennsylvania-based clients. What sets Maryland apart from both neighbors isn't the rate or the small claims limit; it's the 3-year filing deadline, noticeably shorter than the windows typically available elsewhere in the region.
Setting Up Enforceable Late Fees in Maryland
- Write your rate into the contract. "Invoices unpaid after 15 days accrue interest at 1.5% per month" is enforceable and clearer than defaulting to the 6% constitutional rate.
- Reference the rate on every invoice so it's visible without the client needing to dig through the original agreement.
- Don't let a balance sit. With only a 3-year window, follow up promptly on overdue invoices rather than letting them age — the clock starts running from the date payment was due.
- Keep dated records of every invoice and communication, since Maryland's shorter statute of limitations gives you less room for error if a dispute ends up in court.
Maryland's 3-year deadline is one of the shortest in the country. If you have any unpaid Maryland invoices from more than two years ago, don't wait — get a demand letter out or file soon, since the filing window closes faster here than in almost any neighboring state.
Collecting in Maryland
Maryland's District Court Small Claims division handles money disputes up to $5,000 (Md. Cts. & Jud. Proc. § 4-405), with a filing fee of just $11 — among the lowest in the country — plus a roughly $40 service-of-process surcharge. Claims between $5,000 and $30,000 go to the regular District or Circuit Court docket instead.
- Maryland District Court Small Claims: up to $5,000 (excluding interest, costs, and attorney fees)
- District or Circuit Court (regular docket): up to $30,000
- Statute of limitations: 3 years for most contracts (Md. Cts. & Jud. Proc. § 5-101); 12 years for contracts under seal (§ 5-102)
- Post-judgment interest: 10% per year

What late fee rate is enforceable in Maryland? +
Maryland's constitutional legal rate is 6% per year (Md. Const. Art. III, § 57; Com. Law § 12-102), which applies when a contract doesn't specify its own rate. Freelancers can and typically do write a higher rate — commonly 1.5% per month (18% annually) — directly into their contract and invoices, since it's an agreed rate rather than the statutory fallback.
How long do I have to sue over an unpaid invoice in Maryland? +
Only 3 years for most contracts, written or oral (Md. Cts. & Jud. Proc. § 5-101) — one of the shortest general statutes of limitations in the country. Contracts executed under seal get 12 years instead (§ 5-102), but that formality is rare in freelance work, so don't let an unpaid Maryland invoice sit for years before acting.
