What is tax?

To tax (from the latin taxare: to estimate, which in turn is from tangere: to touch) is to impose a financial charge or other levy upon a taxpayer (an individual or legal entity) by a state or the functional equivalent of a state.

Taxes are also imposed by many subnational entities. Taxes consist of direct tax or indirect tax, and may be paid in money or as its labour equivalent (often but not always unpaid). A tax may be defined as a "pecuniary burden laid upon individuals or property to support the government […] a payment exacted by legislative authority." A tax "is not a voluntary payment or donation, but an enforced contribution, exacted pursuant to legislative authority" and is "any contribution imposed by government […] whether under the name of toll, tribute, tallage, gabel, impost, duty, custom, excise, subsidy, aid, supply, or other name."

In modern taxation systems, taxes are levied in money, but in-kind and corvée taxation are characteristic of traditional or pre-capitalist states and their functional equivalents. The method of taxation and the government expenditure of taxes raised is often highly debated in politics and economics. Tax collection is performed by a government agency such as Canada Revenue Agency, the Internal Revenue Service (IRS) in the United States, or Her Majesty's Revenue and Customs (HMRC) in the UK. When taxes are not fully paid, civil penalties (such as fines or forfeiture) or criminal penalties (such as incarceration) may be imposed on the non-paying entity or individual.

What is insurance?

Insurance, in law and economics, is a form of risk management primarily used to hedge against the risk of a contingent loss. Insurance is defined as the equitable transfer of the risk of a loss, from one entity to another, in exchange for a premium, and can be thought of as a guaranteed small loss to prevent a large, possibly devastating loss. An insurer is a company selling the insurance; an insured or policyholder is the person or entity buying the insurance. The insurance rate is a factor used to determine the amount to be charged for a certain amount of insurance coverage, called the premium. Risk management, the practice of appraising and controlling risk, has evolved as a discrete field of study and practice.

An advocate is one who speaks on behalf of another person, especially in a legal context. It is used primarily in reference to the system of Scots law, Anglo-Dutch law, Scandinavian and Israeli law. Implicit in the concept is the notion that the represented lacks the knowledge, skill, ability, or standing to speak for themselves. The broad equivalent in many English law-based jurisdictions is "barrister".

An attorney at law (or attorney-at-law) in the United States is a practitioner in a court of law who is legally qualified to prosecute and defend actions in such court on the retainer of clients. Alternative terms include counselor (or counselor-at-law) and lawyer.

The United States legal system does not draw a distinction between lawyers who plead in court and those who do not, unlike many other common law jurisdictions (such as Britain, which has distinct between solicitors and barrister -or, in Scotland, advocates) or and civil law jurisdictions (such as Italy and France, which distinguish between advocates and civil law notaries). An additional factor which differentiates the American legal system from other countries is that there is no delegation of routine work to notaries public or their civil law notaries (their civil law equivalent).

Who is lawyer?

A lawyer is "a person learned in the law; as an attorney, counsel or solicitor; a person licensed to practice law." Law is the system of rules of conduct established by the sovereign government of a society to correct wrongs, maintain stability, and deliver justice. Working as a lawyer involves the practical application of abstract legal theories and knowledge to solve specific individualized problems, or to advance the interests of those who retain (i.e., hire) lawyers to perform legal services.

The role of the lawyer varies significantly across legal jurisdictions, and so it can be treated here in only the most general terms.
