HMRC figures reveal late filings are heavily concentrated among lower earners, raising concerns about financial access and awareness
Self-employed workers with lower incomes are significantly more likely to miss tax filing deadlines compared to higher earners, according to new data from HM Revenue and Customs.
The findings, based on figures obtained through a freedom of information request by PensionBee, highlight a growing divide in financial compliance across income groups.
Late Filing Rates by Income Level
During the 2023–24 tax year, around 5.9% of self-employed individuals earning below the basic tax rate submitted their returns after the January 31 deadline. This compares to:
- 3.1% of basic rate taxpayers
- 2.7% of higher rate taxpayers
- 2.6% of additional rate taxpayers
In total, approximately 180,000 self-employed individuals filed late, with nearly 94% coming from lower or middle-income brackets.
Why Lower Earners Are Struggling
Experts suggest the issue goes beyond simple oversight. Lower-income self-employed workers often face:
- Limited access to accountants or financial advisors
- Irregular or unstable income streams
- Lower awareness of tax rules and benefits
This combination makes it more difficult to manage strict financial deadlines.
According to PensionBee, many workers may also be unaware that self-employed pension contributions can qualify for tax relief, pointing to a broader knowledge gap.
Financial Pressure and System Challenges
Lisa Picardo, a senior executive at PensionBee, described late tax filing as part of a larger structural problem. She noted that many lower-income self-employed workers operate within what she called an “invisible workforce,” where financial instability and lack of support make compliance more challenging.
For these individuals, missing a tax deadline is often not just a mistake, but a reflection of ongoing financial pressure.
Penalties and Support
Under current rules, missing the self-assessment deadline typically results in an initial £100 fine, with additional penalties possible over time. However, HM Revenue and Customs may waive penalties if a valid reason is provided.
The agency says it is working to improve awareness and support. It runs annual campaigns to help taxpayers meet deadlines and provides guidance through official platforms and customer support services.
In fact, around 11.5 million people successfully submitted their tax returns on time for the 2024–25 tax year.
Why This Matters Globally
While the data comes from the UK, the trend reflects a broader global issue. In countries like the United States, self-employed workers also face challenges related to tax compliance, financial literacy, and income volatility.
As the gig economy continues to grow worldwide, ensuring that independent workers have access to clear information and financial support will be critical.
