HM Revenue & Customs (HMRC) is the UK's tax, payments, and customs authority. HMRC administers the collection of taxes including Corporation Tax, VAT, Income Tax, PAYE, and Customs Duties. Registering with HMRC is a separate process from Companies House incorporation and is required once a company commences business activity or reaches applicable registration thresholds.

What is HMRC?

HM Revenue & Customs (HMRC) is a non-ministerial government department responsible for the administration of the UK's tax system. Its responsibilities include collecting Corporation Tax from UK companies, administering VAT on goods and services, operating the PAYE system for employers, managing Self Assessment for individuals and partnerships, and administering UK customs and import duties. HMRC also administers statutory schemes such as tax credits, Child Benefit, and the Tax-Free Childcare scheme.

Important: HMRC does not incorporate companies (that is the role of Companies House), does not issue business licences, and does not approve foreign investment. HMRC registration obligations arise from taxable activity — such as trading, employing staff, or exceeding the VAT registration threshold — and are separate from the company incorporation process.

HM Revenue & Customs Tax Regimes

Depending on your business activity, HMRC requires registration across several distinct tax regimes depending on your business structure and turnover.

🏢
Corporation Tax (CT600) The primary tax on UK company profits. Corporation Tax is charged at prevailing rates set by HMRC, with companies required to register within three months of commencing business activity. Annual CT600 returns must be filed and tax paid in accordance with HMRC deadlines.
🤝
Value Added Tax (VAT) VAT registration is required once a business's taxable turnover exceeds the prevailing HMRC registration threshold. VAT-registered businesses must file returns and maintain digital records in accordance with Making Tax Digital (MTD) requirements. Voluntary registration is also available below the threshold.
💼
Self-Assessment (SA800/SA100) Required for Sole Traders, LLP members, and Company Directors to report their individual or partnership income.
📈
PAYE (Pay As You Earn) Required to register as an employer. Deducts income tax and National Insurance contributions directly from employee wages.

From April 2023, a tapered rate structure applies with a main rate and a lower small profits rate, with marginal relief available for profits between the two thresholds. Current rates should be verified against the latest HMRC guidance, as they are set by Parliament through the Finance Act process and may change.

HMRC applies a penalty framework for late filing of tax returns and late payment of tax. Penalties vary by tax regime and the length of the delay. For Corporation Tax, initial fixed penalties apply for late CT600 returns, with further tax-geared penalties for significant delays. VAT late submission penalties operate on a points-based system introduced from January 2023. It is important to file all returns and make tax payments on time to avoid penalties and interest charges. Current penalty rates should be verified against prevailing HMRC guidance.
