The ATF file extension is used by various software types, most notably by the TaxAct tax software, as well as H&R Block Tax Software and other applications. An ATF file contains tax data in a text format that stores the tax return information for an individual or business and can include tax calculations, returns, deductions, exemptions and other financial information. The file resembles other text files, though it is formatted differently to suit the needs of the software which created it.

Formatting Details

An ATF file typically includes a header followed by line breaks. The lines within a document are separated using tabulations instead of spaces and preceded by a two-digit indicator code – this code tells the software program how to interpret each line. For example, an indicator code of 01 tells the program that this line contains data about the tax filer, such as their name and address. Other indicator codes are used to represent different financial data pertaining to that specific return.

File Types Similar to ATF

ATF files are related to other file types such as TAX, W2X, TRN, TXF, and DAT. While they may all contain similar financial data, they are opened by different software applications and use slightly different formatting details. Some of these restrictions have been put in place by the IRS for security reasons. Because these files contain essential financial data, it is important to back them up regularly and to take precautionary measures with disk encryption or other means.

After installing the required software, the operating system will usually automatically associate an unknown file type (in this case .ATF) with the new application. If this does not happen, we can help the system a bit by selecting the software for it, which it should always use to open files with the .ATF extension.

When choosing the software we can select the system to use this software every time.

Remember!
Using it for the first time it is good to check whether the .ATF file opened in the application can be read by us and opens in a way that allows us to use it. If everything is in order, select this option the next time you open a file with the .ATF extension. However, if the file has not opened correctly, we have to look for a different software, with which we can open files with the .ATF extension. Select a different software from our list and install it on your computer. After the software is installed, repeat inspection openings of a .ATF file. Sometimes you have to repeat the operation several times.

Other instructions

If none of the programs listed by us to work with the .ATF file has not meet your expectations, you can try searching other websites. But remember to avoid downloading programs "that can open any file". These applications not only have very limited functionality, but may also expose you to expense tens of dollars when purchasing a license.

In the vast majority of cases you will find the program dedicated to support the .ATF file, or any other file format. In addition, there is a chance that it will be a free program, and its functionality (concerning the .ATF file) will be extended to the maximum.

It is also good to check

  • if the .ATF file has no errors
  • or if it has been copied (or downloaded by the browser) thoroughly
In such a case it is best to try to download the .ATF file again from the same source on the Internet (or look for another source). If you received the file from another person, ask this person to re-send it. However, if the file was copied from some media, repeat the copying operation.
