Another type of genealogy record that provides tremendous value is tax records. Like city directories and voting registers, they provide information for us between federal censuses. They also can go back to colonial times.
Types of Taxes
- Income tax
- Federal direct tax
- Poll or head tax
- Real property, e.g., land
- Personal property, e.g., livestock, equipment, carriages, enslaved persons
- Other, such as special levies for roads, schools, etc.
Types of Information
- Date
- Residence address; property, license, or goods; value; tax amount; possibly profession, occupation, or trade
- Name of taxpayer, usually white adult males
- Town/township/city, county, and state of residence
- Owner and/or renter of the property
- Number of white adult males in the home
- Type and value of property
- Livestock owned
- Personal property owned
- Amount of tax owed
- Profession, occupation, or trade
- Number of school-aged children
- Number of enslaved persons
Derivative information, such as birth date, death date, and date of marriage can often be estimated or determined from the presence or absence of a person in a tax list.

Note: Some of the links listed take you to a FamilySearch Collection of digital images. Near the bottom of the page under Film/Digital Notes is the name of each sub-collection. If there is a camera icon at the right of the name (in the Format column) then the collections’ images are browsable. If there is a camera with a key icon, it is only available at a Family History Center or affiliated library. If there is a film reel icon, then it is only available in microfilm format, not digital. To take full advantage, please make sure that you are logged in to FamilySearch. The results may be different if you are signed in, rather than not.
