Yes. You are allowed to “stack” these credits because they fall into separate categories. For example, the Foster Care credit is its own distinct bucket, and it does not share a limit with the general Charitable Organization (QCO) credit.

You can contribute to any or all of the following in the same year:

• Foster Care Organizations (QFCO)
• General Charitable Organizations (QCO)
• Public Schools (Extracurriculars)
• Private School Tuition Organizations
• The Military Family Relief Fund
