Estimated Income - include Annual Bonus or Not?

Hi - I want to ensure that the my estimated income from employment is recorded accurately on HMRC so that my tax code is correct. I am not sure whether I should include an annual bonus in this estimated income. For example: Base salary pa = £50,000 Annual bonus pa (paid as a one off in Jan/Fed each year) = Variable based on performance between £10,000 and £20,000. Should I state that my estimated income is £50,000 base salary only or £60,000 / £70,000 including the annual bonus. Or perhaps £65,000 as a midway point including the bonus. Thanks for any advice on this query.

Hi HMRC experts - would appreciate a response to this query please as I would like to ensure my Estimated Income is accurate on my tax account. Thanks.

Anyone .

Hi interbear,
You would need to include an estimate for your bonus when updating your estimated income. 
Thank you. 

OK thank you for clarifying this.
