What is Self-Assessment Tax Return?
The self-assessment tax return is the system by which HMRC collects tax from individuals and businesses whose tax is not deducted automatically. This includes self-employed individuals, landlords, and additional income such as rental income and saving allowances.
Key Points for Self-Assessment Tax Return Filing Deadline
To meet HMRC requirements, you need to be aware of the following self-assessment tax return filing deadlines:
- 
5 October – Register for Self-Assessment:
 
If you are filing a self-assessment for the first time so, you need to register with HMRC by 5 October. If you are a self-employed individual or landlord, and you have untaxed additional income. You need your Unique Taxpayer Reference(UTR) number to register yourself in HMRC for a self-assessment tax return.
- 
31 October – Submit Paper Tax Returns:
 
If you choose to file your Self Assessment tax return using a paper form rather than the online system, you must ensure that HMRC receives it by 31 October. This deadline applies to those people who prefer or need to submit a physical self-assessment tax return instead of filing online.
If you miss this deadline, you will not be able to submit a paper for your tax return without penalties. So, you must prepare everything for filing your tax return before the self-assessment tax return filing deadline.
- 
30 December – PAYE Tax Collection Option:
 
You must file an online self-assessment tax return by 30 December to allow HM Revenue and Customs (HMRC) to collect your tax debt of less than £3,000 through your PAYE tax code. You can use the 30 December deadline to submit your tax return to HMRC, which will let them adjust your tax code to deduct the owed amount from your earnings or pension during the following tax year instead of waiting for a single payment on 31 January. To qualify for this option, you need to satisfy payroll tax obligations as an employee or company pension recipient. You need to file your Self Assessment tax return by 30 December to avoid paying taxes as a single payment on 31 January.
- 
31 January – File Online Tax Return:
 
If you have not already submitted a paper return by the 31 October deadline, you must submit your self-assessment tax return online through the HMRC website. 31 January is the self-assessment tax return filing deadline for online submission. This method is so easy and faster than to physical submission of self-assessment tax returns.
Being prepared by obtaining your income records, allowable expenses, and HMRC login details should start before the deadline to minimise last-minute stress. The online filing process completes quickly while granting immediate confirmation of results and helps avoid mistakes. HMRC allows taxpayers to use their Time to Pay program which enables them to break down payment obligations across multiple times.
- 
31 July – Second Payment on Account Deadline:
 
If you operate Payments on Account, then the second payment installment becomes due by 31 July. People must follow this process when their tax bill exceeds £1,000 in the past and they do not receive tax income through PAYE payments. The second half of the Payments on Account becomes due on 31 July, while the first payment is required on 31 January for upcoming tax bills. You will receive either a refund or need to make an additional payment during the next 31 January period, depending on the actual tax amount versus your estimated tax.
