Federal Government Taxes

Government expenditures are financed for the most part by government taxes. Below is a table that includes the most important United States federal government taxes and other receipts. The figures are in billions of United States dollars.

Individual income taxes and Social Security taxes are responsible for the majority of the federal government’s tax receipts. After the 2008 recession, revenues declined considerably, but rose again several years later due to a growing economy and increases in the Social Security retirement age.

Estimated federal tax revenue for 2017 is $3,468 billion. Estimated 2017 spending (see previous section) is $4,062 billion. This means that the United States federal government deficit (receipts minus expenditures) in 2017 is expected to be $594 billion. This is smaller than in the years immediately following the 2008 recession. However, historically, the amount is still large and is expected to pose financial problems for future generations.

Social Security Taxes and the Future of Social Security

Social Security or FICA (Federal Insurance Contribution Act) taxes for an individual equal $7.65 of every $100 earned. The Social Security portion of this tax (6.2%) is subject to maximum earnings of $118,500 (2016). The Medicare portion of the FICA tax is 1.45%. There is no maximum earnings limit on Medicare. All income is subject to the Medicare tax. Employers are required to match these percentages, so that the federal government receives 15.3% of each paycheck (up to the maximum earnings amount for the Social Security component) and more from higher earning households as married couples earning more than $250,000 and individuals earning more than $200,000 pay an additional .9% (so the total marginal medicare tax for this group is 2.35% and the total tax from employer and employee combined for this group is 16.2%).

The Social Security program is a pay-as-you-go program. This means that the majority of the tax collected this year pays for benefits of current retirees. For more information about Social Security taxes and benefits, visit http://www.ssa.gov.

The Social Security program has been running surpluses. However, during many years in the past the federal government spent the surplus as part of its regular operating budget (to make the budget look more favorable). There is currently money in the Social Security trust fund, but many people anticipate that because of the large number of Baby Boomers, who are currently retired or soon will be retired, the fund is insufficient to meet the demands in the future.

To fix this problem, either the FICA tax needs to be raised, benefits need to be lowered, or the retirement age needs to be raised (this is already happening). Due to the inefficiencies of the program and the lack of discipline on the part of the federal government to invest the money wisely, the idea of phasing in a privatized system has gained some support. Privatization would allow each worker to invest all or a portion of the tax in her/his own retirement account. The government can still require this retirement contribution. However, each person will have full control over her/his allocation. In order for current retirees and soon-to-retire persons to continue to receive benefits, a privatization program will have to be phased in very slowly. Concerns about this plan include the volatility of the stock and bond markets, transition costs to switch from a public to a private system, and the fear that some people are not knowledgeable enough to invest their own funds.

The United States Tax System

The United States individual income tax system is a progressive tax system. This means that households with higher incomes pay a higher percentage in tax. Because of the recently passed tax reform, the tax brackets for individuals and married couples have changed (see tables below).

For persons filing “single”, the marginal tax rates are as follows:

New Rate New Income Bracket Old Rate Old Income Bracket
10% Up to $9,525 10% Up to $9,525
12% $9,525-$38,700 15% $9,525-$38,700
22% $38,700-$82,500 25% $38,700-$93,700
24% $82,500 – $157,500 28% $93,700-$195,450
32% $157,500-$200,000 33% $195,450-$424,950
35% $200,000-$500,000 35% $424,950-$426,700
37% $500,000+ 39.6% $426,700+

In the new system, an individual who earns, for example, $100,000 is in the 24% marginal tax bracket. This means that for every additional dollar earned over $100,000 (and up to $157,500), this person pays $24 in federal income tax for every $100 dollars earned. Note that this person still only pays 10% over the first $9,525 earned; 12% of the amount in the next bracket, 22% of the amount in the next bracket, etc. Therefore the average tax paid for this person will be less than 24% (see video at the bottom of this page for a sample calculation).

For married couples filing jointly, the marginal tax rates are as follows:

New Rate New Income Bracket Old Rate Old Income Bracket
10% Up to $19,050 10% Up to $19,050
12% $19,050-$77,400 15% $19,050-$77,400
22% $77,400-$165,000 25% $77,400-$156,150
24% $165,000-$315,000 28% $156,150-$237,950
32% $315,000-$400,000 33% $237,950-$424,950
35% $400,000-$600,000 35% $424,950-$480,050
37% $600,000+ 39.6% $480,050+

For most tax payers the marginal tax rate is lower in the new tax system. In addition, there is a higher standard deduction ($12,000 for single filers and $24,000 for joint filers). However, there are fewer deductions for persons who itemize. For example, the limit on deducting state and local taxes is $10,000 (these include state and local income, sales, real estate, or property taxes). Mortgage interest deductions are limited to the interest on the first $750,000 of mortgage debt. In addition, interest on home equity loans will not be deductible (even those taken out before December 31, 2017). The marginal tax rate on long-term capital gains (earnings from selling stocks, bonds and other financial assets) continues to range from 0% to 20% (0, 15, or 20%, depending on your income). High-income tax payers pay an additional 3.8% net investment tax. Short-term (one year or shorter) capital gains are taxed at regular individual income tax rates.

Two frequently discussed tax systems that have been offered as alternatives to the current individual income system are the proportional or flat tax system, and the consumption tax system.

The Flat Tax System

Under a flat tax system, everyone pays the same percentage tax. For example, if the tax rate is 20%, then a household earning $300,000 will pay 20% ($60,000) and a household earning $30,000 will also pay 20% ($6,000). Note that even though the rate is the same, the dollar amount of taxes paid by the higher-income household is higher. Most flat tax systems allow for tax exemptions of the lower-income households. For example, the plan could stipulate that anyone earning up to $25,000 does not pay any tax. This in effect will mean that a household paying $30,000 will pay 0% up to $25,000 and then 20% of the remaining $5,000. The total tax for this household then equals $1,000.

Flat tax systems are considered very simple, because they do not allow households to use deductions in order to lower their taxable income. In the current progressive income tax system, households are allowed to deduct from their taxable income many expenses, including the interest on their mortgage, the interest on their home equity loans, certain medical expenses, certain professional expenses, charitable contributions, certain retirement contributions, and dependent care expenses.

A flat tax system will have a lower tax rate for most people, but will not allow deductions. For this reason, industries, such as the real estate industry and the private welfare industry, may not be happy with the flat tax system. Accountants, tax preparers and government tax auditors will also not be happy with a flat system, as the simplicity of the system makes many of their jobs unnecessary. Does this mean that unemployment will rise, as most of the accounting and tax preparation jobs will be eliminated? The answer is no. Just like throwing bricks through a window doesn’t increase overall employment, complicating the tax system doesn’t increase overall employment, either. Yes, a complicated tax system increases employment of accountants, tax preparers, and government tax auditors, as glaziers also will gain employment in an economy with many broken windows. However, the additional savings that households experience from not having to hire accountants, tax preparers, and not having to pay taxes to the government for the tax preparers will allow these households to increase their spending on other things, just like the baker is able to buy a suit if his window is not broken. Households may now be able to afford a hot tub in their backyard. This certainly sounds more fun than spending this amount of money to have your taxes prepared.

Another characteristic of the flat tax system is that the flat tax rate is lower than the highest marginal tax rate in the progressive system. This means that as your income increases, you will have more incentive to work harder and earn more income. This stimulates economic activity and creates jobs.

The Consumption Tax System

Under a consumption tax system, everyone will pay taxes on the goods and services they buy, instead of paying individual income taxes.

For example, when someone buys a $30,000 car, and the consumption tax is 20%, this person will pay $6,000 in taxes. This makes the price of the car effectively $36,000. This may seem like a big price hike. However, households do not pay any income taxes anymore, so households’ purchasing power stays approximately the same. In other words, the real price of goods and services will remain the same, as households’ after-tax incomes have increased proportionately.

Another advantage of the consumption tax is that it is more difficult to avoid taxes. Everyone that buys non-essential and legitimate (legal) products will pay taxes. This includes people who earn their money in the underground economy (drug dealers, prostitutes, and other workers not reporting their incomes).Most consumption tax plans allow for exemptions on certain products, such as essential foods, housing, and medical care. This means that lower-income households that spend the majority of their income on these items will, in effect, pay little or no tax. The advantage of the consumption tax is that no one will have to complete an individual income tax return, because there is no individual income tax anymore. Taxes will be collected by businesses, who submit the consumption tax to the federal government, just like they are submitting excise taxes to the federal and state governments and sales taxes to most state governments.

The Burden of Tax

The table below shows the percentage of total federal tax dollars and total individual income tax dollars paid by the various income groups, categorized by the amount of their earnings. For example, the top 10% includes those households earning more than $125,195, and the bottom 50% are the households earning less than $36,055 per year. The top 10% of all income earners paid approximately 70% of all federal individual income taxes. The bottom 50% paid less than 3%.

Income Group Households annually earning: Percentage of Federal Individual Income Tax Paid
Top 1% >$434,682 38.09
Top 5% >$175,817 58.95
Top 10% >$125,195 70.17
Top 25% >$73,354 86.42
Top 50% >$36,055 97.22
Bottom 50% <$36,055 2.78

Individual Income Tax System Top Rates

Individual income tax rates in the United States have fluctuated significantly over the years. Tax rates in other industrialized countries have undergone similar changes. Below is a brief historical account of the main changes in the United States.

In 1913, the individual tax rate in the United States was 1% on taxable income of $4,000 for married couples. The rate was 7% on incomes above $500,000.
During the first World War, the highest marginal rate was 77%. It came down to 25% following the war.
Income tax rates rose during the Great Depression. The top rate increased to 75% in 1939, and reached 91% during World War II.
In 1964, the top rate was decreased to 70%.
In 1981, the top rate was decreased to 50%.
In 1986, the top rate was decreased to 28%. The bottom rate increased from 11% to 15%, and the system was simplified to two brackets (15 and 28%).
During the 1990s, the top rate rose to 39.6%.
In 2001, the top rate was decreased to 35% and the bottom rate was decreased to 10%.
In 2013, Congress and the Obama administration approved a top rate to 39.6%.
In December, 2017, Congress and the Trump administration lowered the top rate to 37%.

The Effect of a Tax Cut on the Rich and the Poor

Tax cuts are often controversial because of the effects they have on the different income groups in our society. The following story is an analogy about our tax system.

An Across the Board Tax Cut – Why it Favors the Rich More

Sometimes politicians can exclaim; “It’s just a tax cut for the rich!”, and it is just accepted to be fact. But what does that really mean?
Suppose that every day, ten people go out for dinner. The bill for all ten comes to $100. If they paid their bill the way we pay our taxes, it would go something like this:

The first four persons (the poorest) would pay nothing.
The fifth would pay $1.
The sixth would pay $3.
The seventh $7.
The eighth $12.
The ninth $18.
The tenth person (the richest) would pay $59.
So, that’s what they decided to do.

The ten persons ate dinner in the restaurant every day, and seemed quite happy with the arrangement, until one day, the owner threw them a curve. “Since you are all such good customers,” he said, “I’m going to reduce the cost of your daily meal by $20.” So, now dinner for the ten only cost $80. The group still wanted to pay their bill the way we pay our taxes. So, the first four persons were unaffected. They would still eat for free. But what about the other six, the paying customers? How could they divvy up the $20 windfall so that everyone would get his ‘fair share’?

The six persons realized that $20 divided by six is $3.33. But if they subtracted that from everybody’s share, then the fifth person and the sixth person would each end up being ‘PAID’ to eat their meal. So, the restaurant owner suggested that it would be fair to reduce each person’s bill by roughly the same amount, and he proceeded to work out the amounts each should pay. And so:
The fifth person, like the first four, now paid nothing (100% savings).
The sixth now paid $2 instead of $3 (33% savings).
The seventh now paid $5 instead of $7 (28% savings).
The eighth now paid $9 instead of $12 (25% savings).
The ninth now paid $14 instead of $18 (22% savings).
The tenth now paid $49 instead of $59 (16% savings).

Each of the six was better off than before. And the first four continued to eat for free. But once outside the restaurant, they began to compare their savings. “I only got a dollar out of the $20,” declared the sixth person. He pointed to the tenth person “but he got $10!” “Yeah, that’s right,” exclaimed the fifth. “I only saved a dollar, too. It’s unfair that he got ten times more than me!” “That’s true!!” shouted the seventh person. “Why should he get $10 back when I got only $2? The wealthy get all the breaks!” “Wait a minute,” yelled the first four in unison. “We didn’t get anything at all. The system exploits the poor!”

The nine surrounded the tenth and beat him up. The next night, the tenth man didn’t show up for dinner, so the nine sat down and ate without him. But when it came time to pay the bill, they discovered something important. They didn’t have enough money between all of them for even half of the bill!

And that is how our tax system works.
The people who pay the highest taxes get the most benefit from an across-the-board tax reduction. Tax them too much, attack them for being wealthy, and they just may not show up at the table anymore. There are lots of good restaurants in Europe and the Caribbean.

The Laffer Curve and the Effect of a Tax Cut on Government Revenue

Another tax issue that surfaces from time to time is the effect of a tax cut on government tax revenue. One may expect that if the government cuts taxes, then government tax revenue decreases. However, economist Arthur Laffer predicts that at certain tax rates, government tax revenue increases when the government implements a tax cut, and vice versa. Laffer predicts this because he believes that if tax rates are high and tax rates decrease, people have more incentive to work, and the increase in the work more-than-compensates for the decrease in the tax rate. The now famous “Laffer Curve” (see below) illustrates this phenomenon.

In the graph, this hypothetical country’s government receives no revenue at a tax rate of 0%, because no taxes are paid. Also, at a tax rate of 100%, the government receives no revenue, because there is no incentive to work. At a tax rate of 30%, the tax revenue reaches a maximum level of $600 billion. If the country’s current rate is 75% (the revenue is $400 billion at this tax rate), the government will experience an increase in tax revenue of $200 billion, if it were to cut the tax rate to 30%. Similarly, the government will experience an increase in tax revenue if it were to cut the rate, if the current rate is at any level above 30%.
