use creocoder\taggable\TaggableBehavior;

/**
 * ...
 * @property string $tagValues
 */
class Post extends \yii\db\ActiveRecord
{
    public function behaviors()
    {
        return [
            'taggable' => [
                'class' => TaggableBehavior::className(),
                // 'tagValuesAsArray' => false,
                // 'tagRelation' => 'tags',
                // 'tagValueAttribute' => 'name',
                // 'tagFrequencyAttribute' => 'frequency',
            ],
        ];
    }

    public function rules()
    {
        return [
            //...
            ['tagValues', 'safe'],
        ];
    }

    public function transactions()
    {
        return [
            self::SCENARIO_DEFAULT => self::OP_ALL,
        ];
    }

    public static function find()
    {
        return new PostQuery(get_called_class());
    }

    public function getTags()
    {
        return $this->hasMany(Tag::className(), ['id' => 'tag_id'])
            ->viaTable('{{%post_tag_assn}}', ['post_id' => 'id']);
    }
}

Model Tag can be generated using Gii.

use creocoder\taggable\TaggableQueryBehavior;

class PostQuery extends \yii\db\ActiveQuery
{
    public function behaviors()
    {
        return [
            TaggableQueryBehavior::className(),
        ];
    }
}
