# The Tax Rate, or *How Much Is Taxed?*

Taxes are charged as a percentage of the thing being taxed (which is known as the *Tax Base*); this percentage is known as the *Tax Rate*. The tax base multiplied by the tax rate determines how much is ultimately owed in taxes. That is,

### (Tax base) x (Tax rate) = tax owed

These two things are separate from each other and key to understanding how different people are ultimately taxed differently, with some people basically avoid taxes altogether. Tax rates vary between different types of taxable bases, so focusing wealth in low-rate bases allows people to minimize what they owe in taxes.

There are two different types of tax rates, a flat rate or marginal rates.

## The Flat Rate

The flat rate is straightforward; everybody pays the same percentage in tax no matter how much of the tax base they are paying on. The most common example of this is a sales tax. For a flat rate tax, the rate is the same no matter *how much* of something is being purchased, even if the tax may be a different rate depending on *what* is being purchased (or, as mentioned in the previous section, some types of purchases may be exempt from the tax entirely). This makes it *flat*.

If the sales tax rate on T-shirts (which is the *tax base*) is 7%, then I can buy $10 T-shirts and pay $0.70 in taxes ($10 x 0.07 = $0.70) or I can buy $10,000 of T-shirts and pay $700 in taxes ($10,000 x 0.07 = $700). I am paying 7% of the price of the T-shirts in taxes, no matter how much I buy.

## Marginal Tax Rates

Marginal tax rates require only slightly more math because they change rate depending on *how much* of the base is being taxed. As more of something is taxed, the rate at which it is taxed also increases with marginal tax rates. The important takeaway for this tax structure is that, in discussing the fairness of it, people focus on how the more someone uses or has of the base, the higher percentage they pay of it in tax.

To understand how this works, imagine that the base being taxed at marginal rates falls into several buckets. Each bucket is a *tax bracket*. The first bucket can hold a certain amount - say, $10,000 - and once that bucket has been filled, but only once the bucket is full, the wealth goes into the next bucket. The second bucket, in turn, can hold a certain amount - say, $30,000 - and once *it *is filled, the wealth goes into the third bucket. This continues until Congress doesn’t want any more buckets, and then they make an infinitely large bucket that holds anything above a certain amount. This means that someone making $55,000 with the buckets above would have $10,000 in their first bucket, $30,000 in their second bucket, and then $15,000 in their third bucket. ($10,000 + $30,000 + $15,000 = $55,000, so this accounts for their full income)

Each bucket, then, is taxed at a different rate. The first bucket might be taxed at 10%, the second bucket might be taxed at 12%, and the third bucket might be taxed at 22%. This means that the money in the first bucket is taxed at 10%. The money in the second bucket - and *only* the money in the second bucket - is taxed at 12%. The money in the third bucket - and *only* the money in the third bucket - is taxed at 22%. In the example above, the person making $55,000 has filled their first two buckets and has $15,000 in their third bucket. That means that the $10,000 in their first bucket is taxed at 10%, which means that they owe $1,000 in tax on *that* $10,000 ($10,000 x 0.10 = $1,000). The $30,000 in their *second* bucket is taxed at 12%, which means that they owe $3,600 in tax on *that* $30,000 ($30,000 x 0.12 = $3,600). The $15,000 in their *third* bucket is taxed at 22%, which means they owe $3,300 in tax on *that* $15,000 ($15,000 x 0.22 = $3,300). Putting these together, this person owes $7,900 on their $55,000 income ($1,000 + $3,600 + $3,300 = $7,900).

These bracket sizes (the bucket sizes) and taxation rates are determined by Congress - they can set them however they like and apply them to whatever tax base they like. The best known example of this (and most discussed) is the income tax.

## Taxation Policy

The *Flat Rate* and *Marginal Rates* are the focus of most political disagreements. When people discuss liberal and conservative tax policies, this is usually what is discussed. Liberals tend to think that marginal rates are fair; it is fairer for a rich person to give up their second (or third) yacht than for lots of poor people to give up their food for their families. Conservatives tend to think that flat rates are fair; if everybody pays the same percentage in taxes, then we are all contributing equally.

Whether you are liberal or conservative, however, *nobody* argues that it is fair for the rich to pay *less* in tax (except the rich - they argue they should pay less, but something tells me that their logic isn’t really about *fairness*). It is especially confounding, then, that this is the state we find ourselves in.
