Derecho tributario
Impuesto sobre la renta, IVA, ganancias de capital, impuesto de sociedades y HMRC.
Introducción
El derecho tributario regula la recaudación de impuestos por el Estado y los derechos y obligaciones de los contribuyentes.
Principios fundamentales
Statutory Basis of Taxation — No tax may be levied without the authority of Parliament (Bill of Rights 1689). Every charge to tax must have a clear statutory basis.
Self-Assessment — Most taxpayers are required to self-assess their tax liability and file returns with HMRC. Failure to file or pay on time incurs automatic penalties.
Tax Avoidance vs Tax Evasion — Tax avoidance (using lawful means to reduce tax) is legal; tax evasion (dishonestly concealing income or gains) is a criminal offence. The boundary is determined by the General Anti-Abuse Rule (GAAR) introduced by the Finance Act 2013.
Income Tax — Charged on employment income, self-employment profits, property income, savings, and dividends. Rates include the basic rate (20%), higher rate (40%), and additional rate (45%).
Capital Gains Tax — Charged on the disposal of assets at a gain. Annual exemption applies. Business Asset Disposal Relief (formerly Entrepreneurs' Relief) provides a reduced 10% rate on qualifying disposals up to a lifetime limit.
Corporation Tax — Charged on company profits (trading income, investment income, and chargeable gains). The main rate is 25% for profits over £250,000.
VAT — An indirect tax charged on the supply of goods and services. The standard rate is 20%, with reduced rates (5%) and zero rates for specified categories.
HMRC Powers — HMRC has extensive powers of investigation, information-gathering, and assessment under the Taxes Management Act 1970 and Finance Act 2008. Taxpayers have rights of appeal to the Tax Tribunal.

Escenarios comunes
Freelancer unsure whether to register for VAT
A business must register for VAT if taxable turnover exceeds £90,000 in any 12-month period. Voluntary registration below the threshold is possible and may be beneficial if most customers are VAT-registered. Failure to register when required incurs penalties.
Selling a second property and capital gains tax
The disposal of a property that is not your main residence is subject to capital gains tax. The gain is calculated as sale price minus purchase price and allowable costs. A CGT return must be filed with HMRC within 60 days of completion.
Using a scheme to reduce tax — avoidance or evasion?
Tax avoidance arrangements may be caught by the GAAR if they are 'abusive' — i.e., they cannot reasonably be regarded as a reasonable course of action. HMRC can counteract the tax advantage. Tax evasion (dishonestly concealing income) is a criminal offence under the Fraud Act 2006 and the Criminal Finances Act 2017.
