A Turnitin Similarity Report usually generates within a few minutes — often cited as 10–15 minutes — but it can take longer at peak times. The catch: your first three resubmissions regenerate the report instantly, and from the fourth you wait 24 hours.
Key Takeaways
- A first Similarity Report typically appears within minutes, though heavy submission periods can delay it, per Turnitin’s troubleshooting guide.
- You can resubmit up to three times in 24 hours (if your instructor allows it) and each of those reports generates immediately.
- From the fourth submission onward, a new report only generates after 24 hours — the rule that catches students at deadline.
- The 24-hour clock starts from your first submission of that day, not from each attempt.
- Student and instructor resubmissions share the same three-attempt count.

For a first submission, the Similarity Report is usually ready within a few minutes; 10–15 minutes is the figure most institutions quote. During busy periods — end of term, big deadline days — generation can slow down, and Turnitin documents delay and error conditions in its troubleshooting guide. If the report hasn’t appeared, that’s usually queue time, not a failure.

Why does my Turnitin report take 24 hours after resubmitting?
This is the rule that surprises people. For the first three submissions to an assignment, the report generates immediately. After that, Turnitin only generates a new Similarity Report 24 hours after a fourth or later submission. If you burn through your instant attempts the night before a deadline, you can be locked out of a fresh score until the next day.
| Submission | Report timing |
|---|---|
| 1st (first submission) | Minutes (longer at peak) |
| 2nd & 3rd resubmission | Regenerates immediately |
| 4th onward | Only after 24 hours |
Two more things worth knowing: the 24-hour window starts from your first submission of the day, and instructor resubmissions count toward your three attempts too. So plan your edits — don’t waste attempts on tiny changes.
What should you do if Turnitin is taking too long?
First, wait at least 15–20 minutes before assuming something is wrong; most “stuck” reports are just queued, as Turnitin notes in its student similarity-score guide. Check whether you have hit the resubmission wall — if you are on your fourth attempt, the delay is by design. If the assignment settings or an optional setting route your paper differently, that can change when a score appears. And if you are checking your work before the real deadline, our guide to the best pre-submission check for Turnitin AI risk avoids burning resubmissions entirely. If your number looks off once it lands, here’s why a Turnitin score can change overnight.

Frequently asked questions
How long does Turnitin take on the first submission?
Usually a few minutes — commonly cited as 10–15 minutes. At peak submission times it can take longer, but it is almost always queue time, not an error.
Why is my Turnitin report taking 24 hours?
Because you are past your third submission. The first three attempts regenerate instantly; the fourth and later only generate a new report after 24 hours.
How many times can I resubmit to Turnitin?
Up to three times with instant reports in a 24-hour window if your instructor enabled resubmissions. After that you wait 24 hours per new report.
Does the 24-hour wait start from each resubmission?
No. The 24-hour window starts from your first submission of that day, and student plus instructor attempts share the three-attempt limit.
Can I speed up a Turnitin report?
No, you cannot force it. You can only avoid delays by not exhausting your instant resubmissions and by submitting outside peak deadline windows.
Is a delayed Turnitin report a sign of a problem?
Rarely. Most delays are normal queue time or the resubmission rule. Turnitin’s troubleshooting guide covers the genuine error cases.
