I am/was Self Employed and traded during the period.
*
If you're self employed or a business partner we need to know if you've started trading yet.
If you start working for yourself, you’re classed as a sole trader. This means you’re self-employed - even if you haven’t yet told HM Revenue and Customs (HMRC).
If you have charged a price for products or services, it counts as trading. If you have traded during the period, the requirements are different from if you have not traded. If you traded, but then stopped during the period and ceased to be self employed, you must inform HMRC. You will also be required to complete a self assessment tax return for the period in which you traded.
I still have undeclared income from the period
*
You need to tell HMRC about all sources of income you have had during the tax year. If you have received any income that has not been declared to HMRC then you will need to report it via a self-assessment tax return.
I declared my income and paid tax monthly during the period under the CIS scheme
*
If you are on the CIS scheme you still need to submit a self assessment tax return. It is important that you do this as most CIS workers find that they are due a tax refund of around £2000 per year. Not submitting your tax return will mean that you get a fine and most likely end up paying more tax than you should have.
I registered for Self Assessment as self employed, but did not trade in the period
If you are registered as self-employed you need to provide HMRC with a record of your income during the year, even if your total income was £0.
I worked for more than one employer during the tax year
HMRC needs to know all sources of income that you had during the year. If you are being taxed directly by more than one employer you may be paying too much tax. Check your tax code.
