Is mustn't a possible tag for have to?

[moonlike]

Hi
Can 'mustn't' be used as a possible question tag for have to/has to?
I have to take a day off, don't I? mustn't I?

Thanks

No. Only 'don't I?' works.

No. Only 'don't I?' works.

See please:

I have to (do s/t), mustn't I?
​

I have to work, mustn't I?

I will take your words for granted, though. Thank you, 5jj.

I will take your words for granted, though. Thank you, 5jj.

I think you mean that you will take my word for it rather than take my word for granted.

Please don't. I, like all of use here, can make mistakes. I think that the writer of that article is mistaken in suggesting that 'I have to work, mustn't I' is natural. Others may disagree. Let's see.

I'm with you on that, 5jj. :up:

I agree also. :-D

I agree with 5jj.

I have to work, don't I?
I must work, mustn't I?

I find a combination of those completely unnatural.
