Tax Base

What is Tax Base?

Tax base refers to the total income (including salary, income from investments, asset, etc.) that can be taxed by a taxing authority and is thus used to calculate tax liabilities owed by the individual or the corporation. It serves as a total base on which the tax can be charged.

Tax Base Formula

The tax liability is arrived at by multiplying the tax base into the tax rate. Therefore, it would thus be the tax liability divided by the tax rate.

Tax Base Formula = Tax Liability / Tax Rate

Example of Tax Base

Mrs. Lucia, a businesswoman, happened to earn $20000 last year. Out of this amount, $15000 was subject to tax.

Let us now consider the tax liability assuming a tax rate of 10%.

Tax Liability = Tax Base * Tax Rate

This helps the country’s government to ascertain the total income that it can thus generate for the previous assessment year

#3 – Wide Base Increases Revenue

When a government goes on tax various other items on an indirect basis such as  VATVATValue-added tax (VAT) refers to the charges imposed whenever there is an accretion to a product's usefulness or value throughout its supply chain, i.e., from its manufacturing to its final selling point. It is an indirect tax levied on the product consumption.read more, Central duty, excise duty, imports, and tariffs, etc., its base would now widen. The enhanced base would serve as a source of further revenue for the government. The government can now channel this towards productive purposes such as the development of infrastructural projects, social and welfare spending, etc. Such activities would further the development of the nation.

#4 – Acts as an Accountable Source

Limitations

#1 – Does not Consider the Shadow Economy

It tends to miss out on such income and is not inclusive of the shadow economyShadow EconomyShadow pricing refers to the process of anticipating the value of the money market fund securities based on financial analysis constraints like cost-benefit analysis. It also determines the price of those items which are not ordinarily bought or sold in the market.read more.

#2 – Narrow Base may Impede Growth

If a country tends to stick to tax only one source such as income tax and does not go on to consider the taxation of other indirect sources such as VAT, the base now narrows. This narrowing is a loss of revenue to the government. Because of the loss of such revenue, the income of the government reduces, and it may not be able to undertake developmental activities for the welfare of the economy, and this will impede Growth

#3 – Excludes Exemptions and Tax Relief

The government may give certain incentives for certain sectors, which relieves the ones relying on such occupations, exempt from paying any taxesExempt From Paying Any TaxesTax-exempt refers to excluding an individual's or corporation's income, property or transaction from the tax liability imposed by the federal, local or state government.

Furthermore, various incentives and exemptions introduced by the government help the public in saving or investing in those avenues to take advantage of tax exemptions. However, this seems to be a disadvantage for the government as it will have the tax base reduced to such an extent, which further reduces the revenue to the government.
