SA100 and SA109

Since I have to apply for the split year arrangement, I need to submit the SA109 form together with the SA100 form, however I cannot find where to download the SA100 form, can I submit the SA100 form online and then submit the paper form of SA109 separately? Or where can I find the SA100 paper form? Thank you

Hi,

The SA100 would need to be requested by contacting our Self Assessment team and requesting the form.

Self Assessment: general enquiries

Thank you.
