The Origin of “past due or passed due”
The confusion stems mainly from the nature of past / passed as homophones (words that sound alike but have different functions). Over time, common usage solidified the adjective form past due, rather than a verb-based version.
- Past is an older English word used as noun, adjective, adverb, or preposition (meaning “beyond in time or space”) Daily Writing Tips+1.
- Passed is simply the past form of the verb to pass (i.e., “go by”) Grammarly+1.
In contexts of deadlines and obligations, English speakers came to prefer “past due” because we treat “due” as a state or condition, not an action. The combination “past due” expresses that the deadline has been passed (i.e. the due date lies in the past).
“Passed due” would require parsing “passed” as a verb acting on “due,” which is awkward in conventional English usage. Some older grammarians might allow “has passed due,” but that is not mainstream.
British English vs American English Spelling
In this case, there is no significant British vs. American difference: past due is accepted in both varieties. The confusion is not about spelling but about word choice (past vs passed).
Here’s a comparison table to clarify how “past” and “passed” behave in both dialects:
| Feature | British English | American English | Notes / Examples |
| past due | used and understood | used and preferred | Your invoice is past due. |
| passed due | very rare / considered wrong | very rare / considered wrong | Your invoice is passed due is typically rejected. |
| past / passed general rule | same rules apply | same rules apply | “past” is not a verb; “passed” is a verb Grammarly+1 |
| Other “past / passed” contexts | “past the point,” “time passed” | same usage | We raced past the finish line. / The time passed slowly. |
As you see, both dialects share the same grammatical logic here. The real distinction is between correct grammar and incorrect usage — not national spelling conventions.
Which Spelling Should You Use?
Because this isn’t truly a spelling difference, but a word-choice difference, your decision should depend on audience expectations and style norms rather than American vs British norms.
- In the U.S. (business, legal, accounting contexts) — always use past due. It’s the standard and expected form.
- In the U.K. / Commonwealth / globally — also use past due. Readers will recognize it; “passed due” may even be judged as an error.
- For international audiences — stick with past due for consistency and clarity.
- In creative or conversational writing — avoid “passed due” unless you intentionally stylize or comment on the error.
Thus, the safe and professional choice across nearly all contexts is past due.
Common Mistakes with “past due or passed due”
- Using “passed due” as a default.
✗ Your rent is passed due.
✓ Your rent is past due. - Mixing with other “past / passed” errors.
✗ The time is past it’s limit.
✓ The time has passed its limit. - Treating “past due” as a verb phrase.

✗ Your bill has passed due.
✓ Your bill is past due. - Neglecting subject–verb agreement or reference.

Here are examples across contexts to show correct usage:
- Email to client:
