What is a TA3 file?

TA3 files mostly belong to TaxACT. TA3 files are TaxACT tax return files that store information from completed tax returns.
These files are created when you use TaxACT software to prepare and manage your tax return data. They use a proprietary format designed to secure tax data and ensure accuracy.

They are generated during the tax return process with TaxACT.
They organize your tax information in an internal, non-editable format.
They should be opened using TaxACT software only.
More details are available at the TaxACT website.

FilExt.com tip: To open and view a TA3 file, launch TaxACT software, which is built to interpret the file’s structure.
