Increased Scrutiny of Online Marketplaces and Gig Economy Platforms

HMRC is increasingly leveraging data from popular platforms to identify unreported income. This means that the days of casually underreporting earnings from eBay, Etsy, Uber, Deliveroo, and similar services are coming to an end. The tax authority is actively pursuing several strategies:

• Increased data sharing agreements: HMRC is forging stronger partnerships with online marketplaces and gig economy platforms, resulting in increased data sharing. This allows them to directly access sales figures, transactions, and other relevant information.
• Automated systems for flagging suspicious activity: Sophisticated algorithms are being used to identify patterns indicative of tax evasion, such as unusually high earnings not declared through self-assessment.
• Random audits of sellers/workers: HMRC is conducting more frequent and random audits of individuals using these platforms, focusing on those exhibiting potentially suspicious activity.
• Examples of penalties for non-compliance: Penalties for non-compliance can be severe, including substantial fines, interest charges, and even criminal prosecution in serious cases of tax fraud. This makes accurate reporting crucial for all side hustle earners.

Targeting High-Risk Side Hustles

HMRC is prioritizing its efforts on high-risk side hustles, those with a higher potential for unreported income. This includes:

• High-value goods sales: Individuals selling expensive items online or through other channels face increased scrutiny.
• Lucrative freelance services: Freelancers and contractors earning significant income in high-demand fields are also under increased surveillance.

HMRC is employing advanced techniques to identify these hidden income streams:

• Focus on individuals earning above a certain threshold: Those earning above a specific threshold (which varies depending on the type of income) are more likely to be targeted for review.
• Use of AI and data analytics: Artificial intelligence and data analytics are being used to identify patterns and anomalies in income declarations, helping HMRC flag potentially suspicious activity.
• Increased use of social media monitoring: HMRC may use social media monitoring to uncover evidence of income not declared on tax returns.

Strengthened Reporting Requirements for Freelancers and Contractors

The rules around reporting income from freelance work and contracting are becoming stricter. This means a renewed focus on accurate record-keeping and timely submissions:

• New reporting deadlines and stricter penalties for late submissions: Missing deadlines or submitting inaccurate information will result in heavier penalties than before.
• Emphasis on using Making Tax Digital (MTD) for self-assessment: HMRC is pushing for increased adoption of Making Tax Digital, simplifying tax reporting through digital tools and reducing the likelihood of errors.
• Guidance on what constitutes taxable income from side hustles: HMRC provides clear guidelines on what income from side hustles is taxable, emphasizing the importance of understanding your responsibilities.

US-Inspired Measures: Lessons Learned and Implementation

HMRC is adapting successful US tax enforcement strategies to improve its effectiveness. Key elements include:

• Increased use of data analytics and AI for identifying tax evasion: The US Internal Revenue Service (IRS) has successfully utilized these technologies, and HMRC is following suit to identify patterns of non-compliance.
• Collaboration with international tax authorities to track cross-border income: This collaboration helps track income earned from international sources, ensuring that all earnings are declared.
• Tougher penalties for tax evasion and fraud: The penalties for tax evasion in the US are significant, and HMRC is adopting a similar approach to deter non-compliance.
