Source: My tax returns

Tool: Google sheets

My effective tax rate was calculated by simply dividing the total amount I paid in taxes by my total income. I filed as married each year and we had kids in 2011, 2013, and 2017. My wife and I both graduated college in 2012 but she has stayed home with the kids since the first one was born. She returned to work for the last 3 months of 2022.
