Take a semester off for an internship?

I am a first-year graduate student at my school's MSA program, graduated with a bachelor's in accounting and got offered to work for a mid-size firm for tax through the busy season. I haven't had any internships for accounting as I have worked for a family business for close to 10 years. Just trying to get opinions from everywhere. I ideally want to work for a mid-size doing audit or tax.
