Self-assessment 2018 - What you need to know



If you intend to submit a self-assessment tax return but haven’t done so yet, you need to get your skates on – the deadline is the 31st of January.  You’re already too late to file a paper tax return, but follow our simple guide to get to grips with the online submission.


1) Do you really need to submit a self-assessment?

According to HMRC, you’ll need to send a tax return if, in the last tax year if:

  • you were self-employed – you can deduct allowable expenses
  • you got £2,500 or more in untaxed income, for example from tips or renting out a propertycontact the helpline if it was less than £2,500
  • your income from savings or investments was £10,000 or more before tax
  • your income from dividends from shareswas £10,000 or more before tax
  • you made profits from selling things like shares, a second home or other chargeable assetsand need to pay Capital Gains Tax
  • you were a company director – unless it was for a non-profit organisation (such as a charity) and you didn’t 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 abroadthat you needed to pay tax on
  • you lived abroad and had a UK income
  • 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 didn’t pay enough tax last year – and you didn’t 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

Certain other people may need to send a return (for example religious ministers or Lloyd’s underwriters) – you can check whether you need to. You usually won’t need to send a return if your only income is from your wages or pension.


 2) Have you registered?

Most of you will already have an online account with the HMRC.  If not, you really need to set one up as soon as possible because it can take up to a week to receive your activation code.  Leave yourself time to complete your submission – it takes longer than you might think – but remember you can save an unfinished submission and come back to it if necessary.


3) Determine your income.

Before you start your return, you will need to gather all the necessary documents.  For many of you, that will be a P60 form that shows your income and the tax you’ve paid, along with a P11D or P9D that shows benefits and expenses.  Then you’ll need details of any interest you’ve earned on bank accounts or building societies, plus any other income including investments, income from trusts, and any taxable benefit.  In short, you need to declare everything you earned between 6 April 2016 and 5 April 2017 even including anything that should be tax-free like Isas.  This is where having a dedicated business account is a real timesaver.


4) Determine your outgoings.

Once you have all your income, you need to have details of your outgoings and expenses, as many of these will be tax deductible.  This is a crucial way of lowering your tax bill, particularly if you are self-employed.  They can include everything from travel expenses to stationary.  You can find a handy guide if you’re self-employed here.
