Introduction
His Majesty’s Revenue & Customs (HMRC) is the United Kingdom’s national tax authority. It administers, collects and enforces taxes and certain welfare payments, regulates customs at the border, and administers employer obligations such as PAYE reporting and National Minimum/Living Wage enforcement. HMRC was formed by Parliament in 2005 with the merger of the Inland Revenue and the Board of Customs and Excise.[1][2]

– HMRC is a non-ministerial government department created by the Commissioners for Revenue and Customs Act 2005 and reports to Parliament via HM Treasury.[2]
– For most interactions (registering, filing, paying, and queries) HMRC uses online services on GOV.UK; some transactions and deadlines are time-sensitive — follow GOV.UK guidance for current rules and thresholds.[3]

– 2004–2005: Following government review and Treasury recommendations, Parliament passed the Commissioners for Revenue and Customs Act 2005 to merge Inland Revenue and the Board of Customs and Excise into HM Revenue & Customs (HMRC).[2]
– 2005: HMRC formally established as a non-ministerial department.[2]

Practical steps — How to deal with HMRC (for individuals, employers and businesses)
Note: Always confirm current thresholds, deadlines and exact procedures on GOV.UK (HMRC’s official guidance), as rules and numeric thresholds change.
A. For individuals (employees, pensioners, self-employed)
1. Register for Self Assessment if required:
• If you are self-employed, a partner in a business partnership, receive untaxed income, or have complex tax affairs, register for Self Assessment with HMRC as soon as required (commonly by 5 October following the tax year in which you had income). File online returns and pay by the deadlines (online filing and payment deadline is usually 31 January following the tax year; check GOV.UK for the current schedule).
2. Check your tax code if pay seems incorrect:
• Employers use your tax code to operate PAYE. Query incorrect codes through your online Personal Tax Account or contact HMRC.
3. Claim refunds and allowances:
• Submit P85 when leaving the UK or use Self Assessment/online services for overpayment refunds. Claim eligible allowances (personal allowance, marriage allowance, Blind Person’s allowance, etc.).
4. Keep records:
• Keep pay slips, bank statements, invoices and receipts according to HMRC retention guidance for your situation (different retention periods apply for self-employed individuals and businesses).
5. Use online services:
• Create/use your Personal Tax Account on GOV.UK for easier management of tax codes, Self Assessment, and communication with HMRC.
B. For employers
1. Register as an employer before the first payday:
• Register for PAYE with HMRC and set up RTI reporting (submit a Full Payment Submission — FPS — on or before each payday).
2. Submissions and forms:
• Submit FPS for each payroll, EPS where applicable, provide P45s/P60s to employees as required.
3. Pay liabilities on time:
• Pay PAYE and National Insurance liabilities to HMRC by the relevant deadlines (monthly or quarterly according to your payment schedule).
4. Auto-enrolment and minimum wage:
• Comply with workplace pension auto-enrolment duties and ensure compliance with National Minimum/Living Wage rules; HMRC has enforcement powers for wage compliance.
C. For businesses (VAT, Corporation Tax, Customs)
1. Register for VAT when required:
• Register for VAT when your taxable turnover exceeds the current registration threshold, or voluntarily register if beneficial. (Check GOV.UK for the current threshold and rules.)
2. Corporation tax:
• Register your company for Corporation Tax within three months of starting to trade; file company tax returns and pay Corporation Tax by the due dates.
3. Customs and international trade:
• If importing or exporting, set up required customs declarations and use HMRC’s customs tools or customs agents; follow rules for duties, tariffs and controls.
4. Digital submissions and record keeping:
• Use HMRC’s online services for VAT returns, Making Tax Digital (as applicable), and maintain compliant records (VAT records, invoices, customs paperwork).
D. Paying HMRC and avoiding penalties
1. Payment methods:
• HMRC accepts online bank transfer, direct debit, Bacs, debit/credit card and other payment channels. Use your HMRC reference when paying.
2. Deadlines:
• File and pay on or before statutory deadlines to avoid interest and penalties. If you cannot pay on time, contact HMRC to discuss time-to-pay arrangements.
3. Penalties and appeals:
• If charged penalties or you disagree with HMRC decisions, request an internal review and follow the statutory appeals process, which may escalate to tribunals or courts. Keep records of correspondence and evidence.
E. Disputes, investigations and compliance
1. Cooperate but seek advice:
• If HMRC opens an enquiry/investigation, respond within timescales. Consider professional tax or legal advice—especially for complex or large disputes.
2. Internal review and tribunals:
• If you disagree with HMRC’s determination, request an internal review; if unresolved, appeals can be made to the Tax Tribunal and beyond.
F. Contacting HMRC and using online services
1. Personal Tax Account and business services:
• Use GOV.UK and HMRC online accounts to manage taxes, update details, and access correspondence.
2. Contact channels:
• HMRC offers phone services, online forms, and webchat for certain services; service availability and waiting times vary. For secure queries, use your online account where possible.
3. Security:
• Protect your Government Gateway/Verify credentials; HMRC will never ask for payment by unusual methods (e.g., gift cards). Report suspicious contact immediately.
Record keeping — general guidance
– Keep accurate records of income, expenses, payroll, VAT and customs paperwork as required by law for your category (self-employed, employer, VAT-registered business). Retention periods vary — consult GOV.UK for the exact retention period for your circumstances.
The Bottom Line
HMRC is the UK’s central tax, customs and related welfare administration authority. It plays a critical role in funding public services by collecting taxes and enforcing compliance. Individuals, employers and businesses must register appropriately, submit required returns (PAYE/RTI, Self Assessment, VAT, Corporation Tax), pay liabilities on time, and keep proper records. Use HMRC’s online services via GOV.UK and seek professional advice when disputes or complex tax matters arise.[1][2][3]
