Becoming a contractor infographic
If you’ve always been a full-time employee, it’s possible that you’ve never given a second thought to how the financial year runs. If you plan to become self-employed, however, your schedule will change dramatically. The start of the financial year is April 6th, and it’s vital that new contractors familiarise themselves with key tax deadlines and dates.
Your tax obligations will ultimately depend on your circumstances. If you’ve simply registered as a sole trader, you’ll need to submit a self-assessment return by the end of October (for paper-based returns) or by the end of January (if you plan to make your submission online). Paper returns may be just a few years from extinction, as HM Revenue and Customs (HMRC) is increasingly encouraging people to make digital submissions. More than 85% of taxpayers made online submissions in 2014 - 2015.
If you’ve registered as a limited company, you’ll have other responsibilities to take into account. You need to make your corporation tax contributions nine months and one day after your company’s financial year ends, so it’s crucial that you get your dates right. HMRC is very strict when it comes to late or failed payments.
To ensure that your tax affairs are in good order right from the very start, the infographic below can help you get organised. The statistics highlight the fact that more people in the UK are becoming self-employed, and that the number of self-assessment submissions being handled by HMRC each year is on the rise. They also show that despite the threat of financial penalties for late submissions, many self-assessments are left until the very last minute – a risky thing to do. The timeline shows the key dates that sole traders and limited company owners need to follow.
