Hi Mohammed Rafi,
You would need to answer 'yes' for question 8 as you will have two jobs for a short period of time.
This will ensure the correct tax codes are allocated.
Once you receive your P45 from your previous employer you can then hand this in to your new employer and contact us to review your tax code if your personal allowances need to be transferred to your new employer.
Income Tax: general enquiries
Thank you.
