Extract text from Form 11 and BIOS files (F11)
To convert F11 files to another format, you need Revenue Online Service or other Data software.
To convert other file formats to the "XML Tax Form" file type, you need software like Revenue Online Service or a similar tool.
The .F11 file format primarily serves as an Irish Revenue Form 11, containing tax return data structured in XML. It is generated and processed through the Revenue Online Service (ROS), the official portal of the Revenue Commissioners, or via third-party tax software like Relate PT. A secondary, unrelated use for the .F11 extension is a motherboard BIOS firmware update file specifically for hardware manufactured by Gigabyte Technology.
The main disadvantage of the tax .F11 format is its rigid reliance on specialized Irish tax portals. Users cannot simply double-click to view their tax returns in a normal document layout without logging into ROS or possessing a specialized viewer. For Gigabyte BIOS files, the format is entirely proprietary and useless outside of the motherboard's native Q-Flash utility.
Because the underlying tax document is essentially XML, the best conversion targets are XML, TXT, or CSV for raw data extraction. Converting directly to PDF to replicate the visual layout of a tax form is extremely difficult without the original software, meaning visual layout will be lost during a raw text conversion.
This file format is difficult to open or convert correctly because only the original tax software can properly read, validate, or export the data into a readable layout. Standard online converters fail because they do not recognize the specific Irish tax schemas. Our platform inspects the internal text, allowing you to extract the raw XML data even if you lack the official ROS tools.
Convert.Guru analyzes your F11 file, detects the exact format, and lets you read the text inside.
Users also converted FH11, PDF, XMLS, SN, FMF and F10 files.
If you want to convert F11 file to TMP, TEMP, CACHE, LOG, BAK, OLD, NEW, PART, DOWNLOAD, CRDOWNLOAD, LOCK or PID, you can use Revenue Online Service or similar software from the "Tax Return Data Storage" category. In the File menu, look for Save As… or Export….
To convert DEVICE, CACHE, SOCK, SYMLINK, PID, MOUNT, FIFO, LOG, PIPE, TMP, JUNCTION or TEMP files to F11, try Revenue Online Service or another comparable tool in the "Tax Return Data Storage" category.
The history of Convert.Guru began over 25 years ago in California with Tom Simondi’s file-format database. A former contributor to Space Shuttle development and a software pioneer of the 1980s, Simondi established a trusted resource for file type analysis that was even referenced by Microsoft Windows XP. Today, we use modern technology to process and convert thousands of file formats while continually improving our F11 converter.
