Key Concepts

Marginal Tax Rate

The marginal tax rate is the percentage of tax applied to the last dollar of income earned. It describes how much tax an individual would pay on an additional dollar of income. In tax systems with brackets, this rate changes as an individual's income increases and moves into higher tax brackets, affecting decisions related to additional work or income generation.

Average (Effective) Tax Rate

The average or effective tax rate is the total tax paid divided by the total income earned. Unlike the marginal tax rate, it reflects the overall tax burden on an individual’s income, providing a summary measure of how much of the income is taken away in taxes on average.

Progressive Taxation

Progressive taxation is a system where the tax rate increases as the taxable amount (income) increases. Under this system, higher-income individuals not only pay more tax in absolute terms but also pay a higher percentage of their income in taxes, reflecting an intention to distribute the tax burden more equitably according to ability to pay.

Proportional Taxation

Proportional taxation, also known as a flat tax, is characterized by a constant tax rate applied to all income levels. In this system, every taxpayer pays the same percentage of their income, regardless of how much they earn, which maintains the same burden rate across all income levels.

Regressive Taxation

Regressive taxation is a system where the tax rate effectively decreases as income increases. This means that lower-income individuals pay a higher proportion of their income in taxes than higher-income individuals, potentially placing a greater financial burden on those with less ability to pay.

Tax Incentives and Behavioral Responses

Tax incentive issues and behavioral responses refer to how different tax policies can influence individual and business decisions. For example, a tax system with high marginal rates can discourage additional income generation, while lump-sum or fixed taxes may lead to distortions in work or investment behavior. Policymakers consider these incentives to minimize adverse economic behaviors while achieving revenue goals.

Transcript

00:01 In this problem, we have two people, one with income of 5 ,000, and one with income of 40 ,000, and we're supposed to find the marginal tax rate, the amount of tax pay, the percentage of income paid in tax, which is the tax rate, and use that to classify the proposal as proportional, progressive, or regressive.

00:25 In part a, our tax proposal is all -income and income.

00:34 Taxed at 20%.

00:36 So 20 % would be the marginal rate for both the 5 ,000 and 40 ,000 incomes because the marginal rate is the percent you pay on the next dollar that you earn.

00:50 So if the person with the low income earned another dollar to make a total of $5 ,00, they'd pay 20 % on that last dollar as well as on the original $5 ,000.

01:04 And the same would be true of the higher income person if they earn 40 ,000 and one dollar they paid 20 % of that next dollar just like they paid on the 40 ,000 so the tax would be of a $5 ,000 income the tax would be 20 % 5 ,000 which is $1 ,000 and my tax rate course is the 20 % because that's how we've got thousand, but to find a tax rate, you divide the tax paid by the tax base, which is income.

01:43 So that would be a 20 % tax rate.

01:47 And the tax that the person with a $40 ,000 income would owe would be $8 ,000 because that's 20 % of 40 ,000 would give us $8 ,000 for that person.

02:01 And my tax rate would be 8 ,000 over 40 ,000, which of course is 20%.

02:10 So this would be a proportional tax because a proportional tax means that regardless of your income level, you pay the same percent of your income in tax.

02:26 In part b, all income up to $10 ,000 is tax free, but above $10 ,000, you would pay 20%.

02:36 So for a person in the $5 ,000 income, their marginal rate on that next dollar above $5 ,000 would be zero, since we don't pay tax until we hit $10 ,000.

02:50 For the person with the $40 ,000 income, their marginal rate would be 20 % because that's what they would pay on their next dollar over that $40 ,000.

03:03 So the tax for somebody with $5 ,000 in income would be zero.

03:12 So my rate, of course, would be 0%.

03:22 For the person with an income of 40 ,000, the tax they would owe, they don't have to pay on the first 10, but everything above 10 is taxed at 20%.

03:35 So they have $30 ,000 in income above 10.

03:39 So that's taxed at 20%.

03:42 So the higher income person would owe $6 ,000 in tax and their rate would be $6 ,000 divided by $40 ,000, which would work out to be 15%.

03:58 That would be a progressive tax because the tax rate for the higher income person is higher than what the low -income person pays.

04:11 So a tax is progressive if as income goes up, the percent of pay increases...
