Self Assessment tax returns in East Kilbride

We have the expertise and software to take the headache out of the form filling and compliance aspect of Self Assessment. We can provide you with practical advice on personal tax positions and the planning opportunities available to you. We can complete tax returns, calculate any tax liability and advise you on exactly when to make payments and how much to pay.

Who needs to complete a tax return?

You'll usually need to file a Self Assessment tax return if, for example, you:

• are self-employed as a sole trader and earned more than £1,000 before expenses
• are a partner in a business partnership
• have income from letting property
• have other income that isn't taxed at source, such as some dividends or foreign income

If you're not sure, ask us. It's better to check than to face a penalty.

Key Self Assessment dates

• 5 October: register for Self Assessment if you need to file for the first time, for the tax year that ended on 5 April
• 31 October: deadline for paper tax returns
• 31 January: deadline for online tax returns, and for paying the tax you owe plus your first payment on account
• 31 July: second payment on account due

A late online return gets an automatic £100 penalty, even if you have no tax to pay, and further penalties follow the longer it's late. Our Self Assessment deadlines guide explains the dates for the 2025/26 return in full.

Scottish taxpayers

If you live in Scotland, your earnings, pension and rental profits are taxed at Scottish rates, which have six bands rather than three. We make sure your return is calculated on the right basis. See the Scottish income tax rates and bands.

Making Tax Digital for Income Tax

From 6 April 2026, sole traders and landlords with qualifying income from self-employment and property of over £50,000 must keep digital records and send quarterly updates to HMRC using compatible software. The threshold falls to £30,000 from April 2027 and £20,000 from April 2028. We can set you up with the right software and handle the submissions for you.
