Who needs to complete a self-assessment tax return?
Some of the reasons you need to complete a tax return are listed below if you think you may need to submit a return please don’t hesitate to get in touch for some guidance.
you got more than £2,500 in other untaxed income, for example from tips or commission
your income from savings or investments was £10,000 or more before tax – this includes money from bare trusts or interest in possession trusts
your income from dividends from shares was £10,000 or more before tax – tell HMRC if it was over your dividends allowance
you were a company director – unless it was for a non-profit organisation (such as a charity) and you did not get any pay or benefits, like a company car
your income (or your partner’s) was over £50,000 and one of you claimed Child Benefit
you had income from abroad that you needed to pay tax on
your taxable income was over £100,000
you were a trustee of a trust or registered pension scheme
you had a P800 from HMRC saying you did not pay enough tax last year – and you did not pay what you owe through your tax code or with a voluntary payment
your State Pension was more than your Personal Allowance and was your only source of income – unless you started getting your pension on or after 6 April 2016
What are the deadlines?
The last tax year ended on 5 April 2018. For untaxed income earned during the 17-18 tax year, the online deadline for filing your self assessment tax return and paying your bill is midnight 31 January 2019.
Before the next online tax return deadline comes around, there are several other 2018 Self Assessment dates to bear in mind. It’s unlikely that all of them will be relevant to you, but understand which ones apply so that you don’t miss any important deadlines.
31 July 2018 is the deadline for making your second ‘payment on account’ instalment to HMRC. This will only apply to you if you were self-employed during the tax year 2016-17 and you owed tax of over £1,000 when you submitted your tax return for this period.
5 October 2018 is the dead-line for telling HMRC that you’re self-employed so that they’re aware you need to complete a tax return next year. If you’re already register-ed as self-employed, there’s no need to do this again.
31 October 2018 is the Self Assessment deadline for the tax year 2017-18 if you want to file a paper return rather than filing online. However, most businesses find it easier to file their tax return online – and under the government’s Making Tax Digital plans, filing paper returns may not be an option from April 2020.
30 December 2018 is the deadline for filing your online tax return if you want the tax owed to be collected through PAYE via your tax code. This is only an option if you have some income that’s already taxed through PAYE (i.e. you’re employed as well as self-employed), and if your Self Assessment tax bill for 2017-18 is below £3,000.
We will keep you updated on Making Tax Digital announcements in the future.
