HMRC Warns of £100 Fine for Late Self-Assessment Tax Returns by January 31

## Avoid £100 Penalty and Meet Key HMRC January Deadline in New Update

As the tax season approaches, HMRC has emphasized the importance of meeting the January deadline for self-assessment tax returns to avoid incurring hefty penalties. Taxpayers must submit their returns by January 31 to steer clear of a £100 fine.

Individuals who miss this deadline will face immediate fines, and further penalties may increase if the delay continues beyond three months. People need to file their self-assessment returns, particularly if they have income from self-employment, rental properties, or other sources not taxed at source.

The HMRC update serves as an urgent reminder to ensure all documentation is prepared well ahead of the deadline. Taxpayers should utilize the available online tools and resources provided by HMRC to streamline the submission process.

Accountants and financial advisors stress the importance of timely submissions, pointing out that "the best way to avoid penalties is to keep records updated throughout the year." It is crucial for individuals to double-check their information before submitting to avoid unnecessary delays or complications.
