Thinking of setting up your own business or considering self-employment? Follow HM Revenue and Customs’ simple, 10-step guide to setting up as a sole trader.
1 Getting started: registering as self employed
If you are newly self-employed, or are just starting up your own business you will need to let HM Revenue and Customs (HMRC) know by registering for business taxes. You'll be asked for information about yourself and your business/ self employment. HMRC will then set up tax records for you using the information you provide. You will need to have the following to hand:
Your National Insurance number. In most cases you'll already have this, but if you haven't worked in the United Kingdom before you'll need to get one.
Your contact details (and the contact details of your business if you've started self-employment)
The date your circumstances changed
PAYE information if you have people working for you
2 Registering for Self Assessment online
A Self Assessment (SA) online account will be set up automatically for you at the point of registering as self employed. While filing online is not compulsory (paper returns are still acceptable), there are many advantages – including automatic calculations, faster processing and later deadlines.
3 Receiving your Unique Tax Reference number
Once you've registered for Self Assessment, HMRC will set up your records and send you a letter with a 10-digit reference, called a Unique Taxpayer Reference (UTR). You should keep your Unique Taxpayer Reference in a safe place as it will be needed for SA purposes and in all subsequent correspondence you may have with us.
4 Other things to consider…
If you're self-employed as a sole trader or a business partner, you'll usually need to arrange to pay your Class 2 National Insurance contributions straight away too. You may also need to register for VAT and the Construction Industry Scheme (see contacts below for more information).
5 Keeping a hold of your records
Once you’ve registered as self-employed, you will need to keep business records such as your accounts, evidence of tax that's been paid and other records relating to income and outgoings. You'll need these to help you complete your tax return or to answer any questions from HMRC about a return you've completed. Important documents to retain include: cashbooks, invoices, mileage records, bank statements, receipts for purchases and your P60s if you are also employed. Records can be kept either on paper or computer. If done electronically, then keep a back-up. As a rule, records should be kept for a minimum of six years.
6 Keeping tabs on your expenses
If you're self-employed you usually have various running costs and expenses associated with your business. You can take these costs and expenses away from your business income to work out your profit, and produce accounts. You may also be able to get capital allowances for certain other costs, like machinery, which will also reduce your taxable profits. Common expenses you can claim for include: accountancy services, business bank charges, phone and internet charges, safety wear and utility costs for business use.
7 Sending your first tax return
If you are self-employed, you are responsible for paying your own tax and National Insurance (NI) contributions and must complete a Self Assessment tax form each year.
You'll get a letter, usually in April, telling you when you need to send your first tax return. HMRC might get in touch earlier if you need to send a tax return for a previous tax year. If you don't receive a letter or a tax return, you should contact HMRC.
8 Important deadlines for registering as self-employed
It's best if you register with HMRC as soon as your circumstances change. The latest you should register is by 5 October after the end of the tax year for which you need a tax return.
9 Important deadlines for tax returns
For the 2011 to 2012 tax year (which ended 5 April 2012) your main deadlines are:
paper tax returns – ended on midnight 31 October 2012
online tax returns – by midnight 31 January 2013
final payment of any tax due – by midnight 31 January 2013
For the 2012 to 2013 tax year (which ends 5 April 2013) your main deadlines are:
paper tax returns – by midnight 31 October 2013
online tax returns – by midnight 31 January 2014
final payment of any tax due – by midnight 31 January 2014
There are some exceptions to these deadlines. For further information visit: https://www.gov.uk/self-assessment-tax-returns/deadlines . If your tax return or payment is late you will have to pay a penalty.
10 Filing subsequent returns
For the following year’s payments HMRC will estimate how much you owe based on the tax you paid in the first year. These estimates are split into two separate payments each year: on 31 January when you send in the previous year’s return, and 31 July. A further payment or a repayment may be due based on your final return for the year.
