HMRC: Understanding the Tax Authority's Role and Responsibilities

HMRC, or Her Majesty’s Revenue and Customs, is in charge of tax and duty collection in the United Kingdom. It was founded in 2005 by the combination of the Inland Revenue and HM Customs and Excise. The Inland Revenue managed national insurance and income tax, while HM Customs and Excise oversaw customs charges and VAT.

HMRC tax code manages various taxes, such as value-added tax, business and individual income tax, and national insurance contributions. Its responsibilities include enforcing tax laws, supporting taxpayers, and supervising import/export duties and customs declarations. Businesses can verify tax compliance and the resolution of outstanding liabilities with a tax clearance certificate from HMRC.

What role does HMRC play?

HMRC contributes significantly to the UK economy by gathering funds for government services and initiatives. Its enforcement of tax laws guarantees equity in the UK tax system and is in charge of collecting significant amounts of taxes and charges each year. HMRC services encourage compliance by supporting and advising taxpayers, which lowers the likelihood of tax evasion and avoidance.

HMRC works closely with businesses, providing direction and assistance. In addition, they rely on HMRC agents, who are approved representatives who assist clients. These agents are essential to businesses in assisting them to comply with tax regulations and fulfill their HMRC duties. Their analyses identify possible hazards and areas in which more assistance is required to ensure compliance with tax laws.

What research says about the role of HMRC in the UK’s tax system:

Recent research has provided a clear picture of HMRC’s significance.

“According to UK government statistics, the government received a whopping £1.095 billion (approximately £1.1 trillion) in 2023/24.”

This impressive figure accounts for 40% of the UK’s GDP, the highest level since the early 1980s. This demonstrates the enormous responsibility placed on HMRC to collect a significant portion of the nation’s income.

HMRC reviews and checks

HMRC’s compliance strategy relies heavily on reviews, which help businesses meet their tax obligations. These checks confirm duties and guarantee compliance with UK tax legislation. They are a helpful tool for companies, guaranteeing accountability and staying up to date with changing rules.

In addition to enforcement compliance, it places a high value on moral behaviour when interacting with taxpayers. The HMRC Charter demonstrates their commitment to equity and transparency in business practices by establishing criteria for professionalism, honesty, and respect.
