Rules of Question Tags in English Grammar

• The tense of the statement and the question tag must match.
• Use the Contracted form of "helpful verb" and "not" for the negative question tag.
• The question tag must be negative if the sentence is positive and vice versa.
• Pronouns must always be used in question tags.

It is quite simple to create question tags. Keep in mind that the auxiliary verb in the question tag is used in the sentence's opposing form. In other words, the question tag adopts the auxiliary verb's negative form if the phrase is affirmative. The question tag uses the positive form if the statement is negative.
