Marginal Tax Rate

Definition of Marginal Tax Rate

Marginal tax rate is the tax rate that is levied on the taxpayers for the extra one dollar earned. In many developed countries, the government is following a progressive taxation scheme. In this method, the taxpayer’s tax liability is cut into pieces. The marginal taxes increases as the taxable amount increases. The decision is entirely on the government of the country. It may differ in other countries as well.

Explanation

The marginal tax is the tax on the additional dollar earned by the tax payer in the financial year and the rate may differ from country to country. In a progressive tax scheme, the taxable income is sliced into pieces and is taxed as per the tax rate of the particular tax bracket. It can also be noticed that in the progressive taxation system the marginal tax rate is always greater than the average tax rate. MTR should be known by the taxpayers because they have to make certain decisions on the investment which is to be made in the upcoming year.

Formula

The formula is (Change in Tax /Change in Taxable Income).

If the new taxable income falls within the same tax bracket as the previous taxable income then the MTR will be equal to the Tax Rate applicable to that tax bracket.

How to Calculate Marginal Tax Rate?

• First of all the total income of the tax payer is identified.
• The taxable income is then sliced according to the tax brackets.
• Then the taxes are calculated as per the income and the tax rate by using the formula (Income of the tax payer * Tax Rate).
• We can also compare the average tax rate of the tax payer with that of the MTR and in the progressive tax system, it is usually higher than the average tax rate.

Examples of Marginal Tax Rate

John is working in a manufacturing company his total income comes out to be $50000 this year he requests you to calculate the tax liability for him.

Tax Liability of John

Particulars	Tax Rate	Income ($)	Tax liability
Taxable Income
From 0 to $ 20000	0%	20000	0
From $20001 to $40000	20%	20000	4000
From $40001 to $60000	30%	10000	3000
Above $60001	50%	0	0
		50000	7000

In this example, the marginal tax rate is 30%. The average tax rate will be (Tax Liability/Total Income)*100 i.e. 14%. Therefore this can be concluded that the average tax rate is lower than the marginal tax rate.

Let’s take another example:

Mr. Samuel is a businessman and is also a higher taxpayer. His income for this year comes to $10,00,000. Now we are required to calculate the tax liability of Mr. Samuel.

Tax Liability of Mr. Samuel

Particulars	Tax Rate	Income ($)	Tax Liability
Taxable Income
From 0 to $ 20000	0%	20000	0
From $20001 to $40000	20%	20000	4000
From $40001 to $60000	30%	20000	6000
Above $60001	50%	940000	470000
		1000000	480000

In this example, we can see that the marginal tax rate is 50%. The average tax rate will be (Tax Liability/Total Income)*100 i.e. 48%. Now, this can be concluded with this example if the incomes are high then the average tax rate and the marginal tax rate are almost the same. This is only high when the additional tax component is lower.

Importance of Marginal Tax Rate

• It plays an important role in finding the tax liability of the tax payer.
• It is a tax that is levied on the tax payer for the additional dollar earned.
• The tax payer can identify the tax and can make further decisions on their investments.
• The marginal tax rate is a part of the progressive taxation system. In this system, the high income individual is taxed higher and the lower income segment individual will be charged less tax and this is the best method of taxation.
• In the marginal taxation system, it has also been seen that the high income tax payable can be benefitted because in their case the Average tax Rate and the Marginal Tax Rate are mostly the same with very less difference.

Advantages

• The marginal tax system gives a dimension to the progressive tax system which is very useful nowadays.
• The marginal tax system can make an individual alert about the tax consequences he will have to bear if he is willing to show that extra dollar income.
• The tax payer can get a clear idea of the tax liability he is supposed to pay
• Through the MTR, an individual can make an assessment of the investments he is likely to make this year.
• It is very helpful for all types of tax payers who have that extra income yearly.

Disadvantages

• There are some sentimental values associated with the Marginal tax system. It has been believed that the small tax payer gets discouraged while earning the extra income.
• The extra income brings in the Marginal Tax liability which is higher than the Average Tax system and thus many tax payers are not willing to show that income and try to get the deduction.
• Sometimes deduction is also very difficult to claim therefore they have to pay the higher tax for the income earned and thus is very difficult to implement such a tax system in the country.

Conclusion

The MTR is the rate of tax that is levied on the extra dollar income. There are certain advantages and disadvantages of the system but the purpose of this tax system is very simple. The higher the income the lower will be the tax. The individual who is earning higher incomes will find no difficulty in paying the marginal tax because the average tax rate and the marginal tax rate are the same in their case. It is also a fact that for the medium earning individual the rate is too high compared to the average tax rate.
