Self-Assessment Tax Return: Top 10 tips to avoid any mistake | Online Account Filing

Self-assessment tax return (SA100) deadline is just two weeks away; the filing pressure is already building up. But don’t worry, leave the hassle slowly on the floor, because we’ve got your back with our tips that will help you avoid any sort of mistakes that people, in general, make while preparing and filing the self-assessment tax return. So here you go…

1. Find out if you really need to file a self-assessment return

Despite being the first and the most basic tip, identifying your status has the utmost importance to figure out if you even need to file a return. The following persons need to file self-assessment tax return SA100:

  • A person self-employed as a ‘sole trader’ and earning more than £1,000
  • A partner in a business partnership
  • A person may file a self-assessment return to claim some income tax reliefs
  • A person may file a self-assessment return to prove he/she is self-employed, for example to claim Tax-Free Childcare or Maternity Allowance
  • A person who’s only income is from wages or pension but also has any other untaxed income, such as money from renting out a property, tips and commission, income from savings, investments and dividends, foreign income etc.
  • Most employees paying tax under the PAYE system are not required to file a tax return. However, some employees may have income that has not been taxed at source and needs to be declared to HMRC. Such a person shall do so by submitting a self-assessment tax return.
  • A person who is director of a Company and receiving untaxed salary or dividends.
  • If a person receives any letter from HMRC requiring him/her to file the self- assessment tax return.

If you fall in any of the aforementioned categories then you’ll have to mandatorily file self-assessment return.

It’s important to be clear of the fact that only business expenses can be claimed from the business profits. In other words, you are not allowed to claim your private expenses. Suffice it to say, not all the business expenses can be claimed alike, some can be claimed partially and/or some over the years instead of claiming in one go.

4. Have proper paperwork in place

While working throughout the year, there are a number of papers and documents executed. These hold a crucial use at the time of finalisation of accounts and filing of tax returns. For instance, the various PAYE forms P60, P45, P11D will help you in completing your self-assessment. Other papers include-receipt of any amount donated to charity, expense records, mileage records, number of hours spent working at home, bank statements, invoices and receipts etc.

5. Enter correct figures

A number here or there, a number less or extra and alike mistakes can result in drastic blunders. You might as well end up overpaying or underpaying taxes, both of which will impact you negatively. It is very important to double-check the figures you enter into your tax return.

6. Take some help of an accountant

The easiest way to stay stress-free while the self-assessment hassle prevails is to sign up for services of an expert in the field. All you’ll have to do is to provide all the financial data you have and let them prepare and submit the tax return to HMRC on your behalf. This would ensure that none of the important information has been missed and you can sit back and relax, rest assured since the information will be in the hands of an expert. Moreover, if the business’ affairs are complex there is a high probability that you might miss out on valuable reliefs and allowances you might be unaware of.

7. National Insurance and Unique Taxpayer Reference number

NI number basically helps in matching the national insurance contributions made against the name of the person. This number also acts as a reference ID when you need to contact the Department of Work and Pension and HMRC with regards to national insurance. Similarly, UTR number is a 10 digit code that helps HMRC in ensuring that everyone pays what they owe and receives any money back that they might be entitled to in terms of taxes.

Both NI number and UTR are included in the return and due to the key role they play, it is important to ensure that they are correct.

8. Enclose all relevant supplementary pages

Supplementary pages are used by HMRC to fetch additional information from the assessee, not covered in the main return. They are part of the tax return and as important as the main return. Supplementary pages include:

  • Income from UK property
  • Foreign income and gains
  • Income from employment
  • Capital gain summary etc.

9. Stick to deadlines to avoid penalties
