Regular users don't have the ability to change file ownership (only group, assuming they're a member of the target group and own the file), so this is mainly a consideration if you're running tar as root. By default, if you're running as root, GNU tar assumes the --same-owner switch, which preserves the ownership in the archive. If the IDs are different, you can use --owner or --owner-map to translate the IDs. If you need to get even trickier, you can use --to-command and pass the stream to your own custom filter.
