What Is Form 8621?

What others say

PFIC reporting can be particularly complex. The Form 8621 preparation service has streamlined the PFIC preparation process for us. The support team is consistently responsive and knowledgeable.

Sharon (CA, EA)

My experience with Expat Tax Tools has been extremely positive and the personalised assistance provided helped to eliminate a great deal of stress. When I realised an investment account we opened 18 years ago was a PFIC, I was alarmed. However, when I began to understand the reporting requirements of Form 8621, I was really horrified!

Finding a tax service with 8621 expertise in Australia isn’t easy. I felt confident my forms would be completed accurately which was important to me and the supporting Guides were very helpful. I can highly recommend Expat Tax Tools if you’re faced with sorting through the complexities of Form 8621.

I have been using the 8621 calculation program since 2015. Up until I found this wonderful product I was doing my PFIC calculations on Excel worksheets which was very time consuming. I was desperate to find a way to be able to calculate and track PFICs in a more efficient manner. With the 8621 program, it has been a boon to profits and efficiency.

I find that the program shows the calculations clearly and shows you what the tax forms will look like making the review process easier as well. Whenever I had a computer issue with the program (a tech issue), George was always there quickly to fix the issue. Their customer service is top notch.

I have been using Expat Tax Tools’ 8621 Calculator for a number of years. It is a lifesaver. Anyone who has done PFIC calculations on their own knows well how complex and confusing it can get. The 8621 calculator streamlines the process and is incredibly user friendly. It does calculations in seconds that would take me hours to accomplish, and is obviously much more accurate and precise.

George has also continued to improve it over the years, continually adding new features. If I ever had a question regarding the calculations, George was always there with an answer. Thanks for the great product and service!

Ariel Rosenthal, CPA

Expat Tax Tools has saved me and my clients a ton of time and money by making Form 8621 preparation quick and painless. What used to take countless hours of spreadsheet calculations is now at worst a very simple data entry task.

When a client has PFICs to report, it is no longer a problem. Customer service is also extremely helpful and immediately responsive. Very excited to have this product!
