It's Important, Isn't It?
Most questions in English use this structure:
(Question Word) + Auxiliary + Subject + Verb Form + (objects) + ?

Is the tech support department going to replace the defective pin pad today?
Question tags are used to confirm information that the speaker knows, or believes to know. This conversational form is used to check that the speaker has understood something.
Form questions tags by making a statement followed by a comma and the OPPOSITE (positive -negative, negative - positive) form of the matching auxiliary verb in the same tense.
You won't need overdraft protection, will you?
The bank doesn't do invoicing for their fees, do they?

Future with 'Will':

Request with 'Would':

Use question tags in order to do the following:
- To confirm information
- To continue a conversation
Sometimes, question tags are used sarcastically or in a joking manner. This type of usage depends on the context and the speaker's tone of voice.
Exception: When using the verb 'to be' as the auxiliary verb in a question tag with the subject I (rhetorical) use the form "am I?".
I'm not going to be late, am I?
I'm not involved in that sale, am I?
