Self Assessment Deadline & Prep Kit

Every date, every document, and what you'll owe — for the 31 January deadline.

A workbook to help UK sole traders and landlords get organised ahead of the Self Assessment deadline: the key dates that apply to you, a document/information checklist, a rough tax estimate, and what you might actually need to pay and when. It does not calculate your real tax bill, file anything on your behalf, or replace professional advice.

What's in it

  • Key dates and HMRC's penalty structure
  • Document and information checklist
  • Tax and payment due for sole traders and landlords
  • Payments on Account worked out
  • Quick-start guide (Word)
