How to Fix Threads ‘Permission Denied’ Error When Tagging Users

The Threads app shows a “Permission Denied” error when you try to tag another user in a post or reply. This error usually appears because the account you are tagging has restricted who can tag them in their privacy settings. It can also occur if your account has been temporarily limited for posting too many tags in a short period. This article explains the exact causes of this error and provides step-by-step fixes to resolve it.

Why Threads Shows “Permission Denied” When Tagging Users

The “Permission Denied” error when tagging in Threads has two main root causes. The first cause is the target account’s privacy setting that controls who can tag them. This setting is managed through the linked Instagram account because Threads uses Instagram’s infrastructure for identity and relationships. If the target user has set their tag permission to “No One” or “People You Follow” and you do not follow them, the tag request is blocked before it reaches the server.

The second cause is your account being temporarily limited by Threads for excessive tagging behavior. Threads applies rate limits to prevent spam. If you tag more than a certain number of unique accounts per hour or per day, the system automatically denies further tag attempts and shows the “Permission Denied” error. This limit is not visible in the app settings and resets after a cooldown period, usually 24 hours.

How Tag Permissions Work Across Instagram and Threads

Threads does not have its own tag permission settings. The permission is inherited from the Instagram account linked to your Threads profile. When you try to tag a user, Threads checks the Instagram privacy database to see if the target account allows tags from you. If the target has blocked tags from non-followers or everyone, the error appears. There is no way to override this from Threads alone.

Steps to Fix the Tag Permission Denied Error

Follow these steps in order. After each step, try tagging the user again.

1. Ask the target user to check their Instagram tag settings
   The person you are trying to tag must open Instagram, go to their profile, tap the menu icon (three lines), select Settings and privacy, then Privacy, then Tags. Under “Allow Tags From,” they need to select “Everyone” for you to tag them. If they select “People You Follow” you must follow them on Instagram. If they select “No One” tagging is impossible.
2. Follow the target user on Instagram
   Even if the target allows tags from “People You Follow,” you must be following them on Instagram. Open Instagram, search for the user’s profile, tap Follow, then return to Threads and attempt the tag again. The permission syncs immediately.
3. Wait 24 hours after excessive tagging
   If you have tagged many accounts in a short time, your account may be rate-limited. Stop tagging for 24 hours. The limit resets automatically. Do not try to tag during this period as it may extend the restriction.
4. Use the full username with the @ symbol
   Type the exact username including the @ symbol, for example @username. Misspelling the username or omitting the @ will result in a failed tag that may count toward your rate limit.
5. Log out and log back into Threads
   Go to Settings > Account > Log out. Close the app, reopen it, and log back in. This refreshes your session and clears any temporary flags that might interfere with tagging.

If You Cannot Change the Target User’s Settings

You cannot change another user’s privacy settings. If the target refuses to switch to “Everyone” or does not accept your follow request, you cannot tag them. In this case, mention them in the post text without using the tag feature, or ask them to tag themselves in a reply.

What to Do If the Error Persists After the Main Fix

If you have followed all steps and still see the error, consider these additional causes and solutions.

Threads Account Limited for Spam Behavior

Repeated tagging of users who do not follow you back can trigger an automatic spam flag on your account. This flag can last up to 48 hours. During this time, you cannot tag anyone. The only fix is to stop all tagging activity and wait. Avoid sending direct messages or posting repetitive content during this cooldown.

Tagging a User Who Has Blocked You

If a user has blocked you on Instagram or Threads, you will see the “Permission Denied” error when trying to tag them. You cannot tag a user who has blocked you. Verify the block by checking if you can view their profile on Instagram. If you cannot, you are blocked and tagging is impossible.

Tagging a Deactivated or Deleted Account

If the target account has been deactivated or deleted, tagging will fail with a similar error. The username may still appear in search results for a short time, but the tag will not go through. Confirm the account status by visiting their Instagram profile directly.

Tagging Restrictions in Threads vs Instagram

Item	Threads	Instagram
Tag permission location	Inherited from Instagram	Profile > Privacy > Tags
Rate limit for tagging	Approx 10 tags per hour	Approx 20 tags per hour
Can tag users who block you	No	No
Can tag users with private accounts	Yes, if they allow tags from everyone	Yes, if they allow tags from everyone
Error message shown	“Permission Denied”	“Couldn’t tag this person”

The tagging restrictions on Threads are stricter than on Instagram. The rate limit is lower, and the permission check is identical. If you encounter the error on Threads, the same tag attempt would likely fail on Instagram as well.

You can now resolve the “Permission Denied” error by checking the target user’s Instagram tag settings, waiting out a rate limit, or verifying the user’s account status. The most reliable next step is to ask the person you want to tag to open Instagram and set their tag permission to “Everyone.” As an advanced tip, avoid tagging more than five unique users per hour on Threads to stay well under the rate limit and prevent future restrictions.
