Many people find themselves rushing to input all relevant information before the deadline, which often causes mistakes – resulting in costly penalties.
To make things easier, taxation specialists GoSimpleTax have gone ahead and put together this quick and easy self-assessment checklist to have by your side throughout the process. Including deadlines for completing your self-assessment and the personal tax return items you’ll need.
Avoid the dreaded rush of a last-minute tax return and read on to discover everything you’ll need to complete your tax return.
Before You Begin
Do You Need to Register Self Assessment?
It isn’t just sole traders who need to fill in a tax return. Find out if you need to do so here.
If you haven’t registered for self-assessment, you should do so here immediately. You should allow seven to ten days for your UTR to arrive.
You will also receive a PIN number that allows you to register for the Government Gateway, giving you access to the HMRC online services.
? My PIN has arrived
? I have my UTR number
? I have a Gateway ID
Partners and members of LLPs should register here, and in non-LLP partnerships, one member should also be nominated to register the partnership itself.
? I have registered
Self Assessment Tax Returns Deadlines
Your tax return covers the financial year from 6th April of the year before to 5th April of the year the self-assessment refers to.
You should complete your tax return online by 31st January each year, or by post by the 31st October each year.

Find the right self-assessment form
