Statute of Limitations for Account Stated / Open Account in United States (Federal)

6 min read

Published March 22, 2026 • By DocketMath Team

Overview

For federal civil lawsuits involving unpaid bills, lawsuits often fall under debt-related theories such as account stated or open account. While these labels can differ across jurisdictions and practice areas, the federal “Statute of Limitations” (SOL) framework is usually driven by the federal statute that supplies the cause of action (or, in some cases, the default limitations period for certain contract-like claims).

In this federal-focused reference page, the key takeaway is straightforward:

  • No claim-type-specific sub-rule was found for “account stated” vs. “open account.”
  • Therefore, the period below reflects the general/default limitations period you should treat as the baseline when applying the federal SOL in the absence of a more specific rule.

DocketMath’s statute-of-limitations calculator is built to help you translate dates (when the claim accrued vs. when the suit was filed) into an SOL timeline you can compare at a glance. For account-type disputes, that date mapping usually matters as much as the statute itself.

Note: This page describes the federal baseline period found for the calculator’s jurisdiction setting. If your case is governed by a different federal limitations statute tied to a specific claim type, that more specific statute can override the default.

Limitation period

For the United States (Federal) jurisdiction setting, the general/default SOL period is:

  • 0.1 years

In plain language, that is roughly about 36–37 days (0.1 × 365). Because limitations computations are sensitive to how “accrual” is defined and how days are counted under the relevant procedural rules, treat the calculator’s result as a timeline to verify against the exact accrual and filing dates in the record.

What “0.1 years” means in practice

When you run the calculator, you’ll typically provide two date inputs:

  • Accrual date: the date the claim legally “starts” for SOL purposes.
  • Filing date: the date the complaint (or other initiating filing) was filed.

Then DocketMath computes whether the elapsed time fits within the baseline limitations period.

How outputs change

  • Earlier accrual date → elapsed time increases → higher chance the claim is time-barred under the default period.
  • Later accrual date → elapsed time decreases → lower chance of SOL dismissal.
  • Later filing date → elapsed time increases → higher chance of SOL issues.
  • Earlier filing date → elapsed time decreases → lower chance of SOL issues.

Warning: SOL outcomes depend on more than date math. Federal accrual rules and any tolling or suspension can materially change the result even when the baseline period is short.

Key exceptions

Even when the default SOL appears short, federal cases often turn on whether an exception or adjustment applies. Below are common categories to watch, framed in a practical way for how they affect SOL calculations.

1) Tolling (pauses or extends the clock)

Tolling can effectively change the elapsed time the court counts. Examples include certain statutory tolling provisions, equitable tolling, or delays caused by circumstances recognized by law.

Calculator impact: If your inputs reflect only calendar time (accrual → filing) with no tolling adjustments, the result can understate the likelihood a claim remains timely.

2) Accrual definition differs from “when the invoice was due”

For account-type disputes, parties sometimes treat “accrual” as “the due date,” but federal accrual is often tied to when the claim becomes legally enforceable.

Calculator impact: If the true accrual is later than the due date, the same filing date may move from “outside” to “within” the default 0.1-year window.

3) Continuing obligations or partial performance arguments

Some disputes involve ongoing performance, repeated statements, or installment-like conduct. When that affects enforceability, it can shift accrual timing.

Calculator impact: Different accrual dates can produce very different outputs when the baseline window is measured in days.

4) Removal or procedural timing (filing date matters)

If a case is filed in one form or forum and then later amended, removed, or re-filed, courts may treat different procedural events as the operative “filing” for SOL purposes depending on the posture.

Calculator impact: Using the wrong “filing date” can incorrectly label a claim untimely.

Pitfall: With a baseline period of 0.1 years, even a difference of one or two weeks can flip the result. Make sure the accrual and filing dates you feed into DocketMath match the dates the court is most likely to treat as controlling.

Statute citation

For the federal jurisdiction baseline used here, the calculator’s default period is reflected as:

  • General SOL period (Federal): 0.1 years

This federal baseline approach aligns with general discussions of SOL concepts in federal contexts, including limits on how long claims can be brought under statutes of limitation.

Note: This page does not identify a separate, claim-type-specific SOL statute for “account stated” or “open account.” The brief explicitly states that no claim-type-specific sub-rule was found, so the general/default period above is the rule being applied.

Use the calculator

DocketMath’s statute-of-limitations tool (/tools/statute-of-limitations) is the quickest way to convert dates into a “timely vs. time-barred” comparison using the Federal default period of 0.1 years.

Step-by-step: what to enter

Check your facts, then enter:

  • Accrual date (YYYY-MM-DD)
  • Filing date (YYYY-MM-DD)

Then review:

  • The elapsed time between dates
  • Whether that elapsed time is within the 0.1-year baseline

What to look for in the output

  • If elapsed time ≤ ~36–37 days: the claim may be considered timely under the default baseline (subject to tolling/accrual nuances).
  • If elapsed time > ~36–37 days: the claim is likely outside the default baseline, again subject to any recognized exceptions.

If you’re testing multiple theories (for example, different potential accrual dates tied to invoice due dates vs. later account statements), run the calculator for each accrual candidate and compare how the result shifts.
