Grammar explanation
We can add question tags like isn't it?, can you? or didn't they? to a statement to make it into a question. Question tags are more common in speaking than writing.
We often use question tags when we expect the listener to agree with our statement. In this case, when the statement is positive, we use a negative question tag.
She's a doctor, isn't she?
Yesterday was so much fun, wasn't it?
If the statement is negative, we use a positive question tag.
He isn't here, is he?
The trains are never on time, are they?
Nobody has called for me, have they?
If we are sure or almost sure that the listener will confirm that our statement is correct, we say the question tag with a falling intonation. If we are a bit less sure, we say the question tag with a rising intonation.
Formation
If there is an auxiliary verb in the statement, we use it to form the question tag.
I don't need to finish this today, do I?
James is working on that, isn't he?
Your parents have retired, haven't they?
The phone didn't ring, did it?
It was raining that day, wasn't it?
Your mum hadn't met him before, had she?
Sometimes there is no auxiliary verb already in the statement. For example, when:
... the verb in the statement is present simple or past simple and is positive. Here we use don't, doesn't or didn't:
Jenni eats cheese, doesn't she?
I said that already, didn't I?
... the verb in the statement is to be in the present simple or past simple. In this case we use to be to make the question tag:
The bus stop's over there, isn't it?
None of those customers were happy, were they?
... the verb in the statement is a modal verb. Here we use the modal verb to make the question tag:
They could hear me, couldn't they?
You won't tell anyone, will you?
If the main verb or auxiliary verb in the statement is am, the positive question tag is am I? but the negative question tag is usually aren't I?:
I'm never on time, am I?
I'm going to get an email with the details, aren't I?

Hello Baxtyar,
Need is a verb which is in the process of change. In the past, need was a full modal verb and its grammar was in line with other modal verbs. Thus, questions were formed with inversion:
Need you do that?
However, in modern English this sounds highly archaic and unnatural. Instead, we form questions as we would with other non-modal verbs such as want:
Do you need to do that?
This is the reason why need is not used in question tags in modern English. However, in some aspects need still has apsects of its modal verb roots. We can form a negative with or without an auxiliary (don't need or needn't) and can make a perfect form (need have), for example.
Ought is undergoing a similar process, but it still retains most of its modal grammar and can be used in question tags. In the future, I expect it will follow the same path as need.

Hello Baxyar,
For sentences with need we form question tags with do:
You need to study hard, do/don't you?
We don't use need in question tags.

Hello Bharati,
A tag question is a dependent clause attached to the main clause, with a pronoun referring back to a noun in the main clause. Downing uses the term 'abbreviated clause' and defines tag questions as follows:
