Be prepared:
Self-assessment is the system HMRC uses to collect income tax. By registering, you will gain access to your UTR and other necessary data.

Collect All Documents:
Income details, bank statements, information on untaxed income, as well as records of income and expenses for sole proprietors are required.

1. Complete the Online Form:
   After logging in, complete the appropriate sections of your return, remembering about your earnings from various sources and possible deductions.
2. Double Check All Data:
   Before sending your return, make sure all information is correct. You can make changes up to 12 months after the original deadline, but it’s better to do it right the first time.
3. Ask for Help If You Need:
   HMRC offers online and telephone support. You can also seek help from a professional accountant office@seperaaccounting.co.uk
4. Pay your bill on time:
   After submitting your return, you will find out how much tax you have to pay. HMRC accepts payments on the day they are made, even on weekends.
5. Watch out for the Tax Code:
   If your tax amount seems incorrect, check your tax code and contact HMRC if you are unsure.
6. Do not be late:
   Delay could cost you up to £1,000 in fines, with additional penalties imposed after 6 and 12 months, along with interest.
7. Additional Possibility: Tax Refund for Working from Home
   If you have worked from home for the last four years, you can claim a tax refund. This is important information for many employees who may not be aware of this right.
