“Complete” works as both an adjective and a verb, while “completed” is the past tense or past participle form used to show an action already finished.
Use “complete” for something whole or to describe an action happening now; use “completed” when talking about an action that already happened.

When to Use “Completed”
As a Past Tense Verb
When an action already finished, completed is the word you need. “He completed the project last week.” This tells the reader the action is over.
As a Past Participle
Completed also pairs with helping verbs like have, has, or had, or shows up in passive voice. “The application has been completed” puts focus on the result, not who did it.
Correct Usage Examples
- The complete manual arrived today. (adjective)
- I complete my timesheet every Monday. (present verb)
- She completed her degree in 2023. (past verb)
- The building has been completed ahead of schedule. (past participle)
Common Mistakes to Avoid
A frequent error is writing “task complete” when the sentence structure calls for completed — such as after “has” or “was.”
Another slip is using completed where a simple adjective like complete fits better, making sentences sound clunky.
