The Taxman Comes for Homer

Last week I wrote about the Simpsons’ mortgage payment. In short, I found that using a reasonable assumption of Homer’s income, the median housing price, and the rate of interest, the Simpsons are likely paying less of their household budget on housing today than in the 1990s.

But what about the family’s taxes? Are they getting squeezed by the taxman? Taxes are referenced throughout The Simpsons series. Here’s an article that collects a lot of the references. And that makes sense: the Simpsons are a normal American family, and normal American families love to complain about taxes.

Using the same reasonable assumption about Homer’s income from last week’s post (that Homer earns a constant percentage of a single-earner family, rather than merely adjusting for inflation), we can calculate the family’s average tax rate and how it has changed over the year. Conveniently, “average tax rate” is just economist speak for “how much of your family’s budget goes to the government.”

First, let’s just look at the federal income tax, since this is where most of the changes happen. Don’t worry, I’ll add in payroll taxes below, though this is a constant percent of the family’s budget since it is a flat tax on income!

The chart below shows the average tax rate the Simpsons paid for their federal income taxes. I didn’t go through every year, because: a) it’s a lot of work (I’m doing each year manually); and b) it’s more interesting to look at years right after or before major changes in the tax code. So no cherry picking here — the years selected are picked to tell a mostly complete story.

I’ll now briefly explain each of the years chosen, and what changes in the tax code impacted the Simpsons. But as you can see, just like their mortgage payment, the Simpsons are now spending less of their household income on federal income taxes (don’t worry, the trend is similar with payroll taxes included). In fact, they are now getting a net rebate from the federal government, and have been since the late 1990s!
