Extract text from 2015 tax returns (T15)
To convert T15 tax returns to another format, you need H&R Block 2015 or other Data software.
To convert other file formats to the "Tax Preparation Data" file type, you need software like H&R Block 2015 or a similar tool.
The .T15 file extension is a proprietary data format created by H&R Block desktop tax preparation software. It stores a user's complete federal and state tax return data for the 2015 tax year, including IRS forms, schedules, and sensitive personal financial information.
The primary software required to natively open and print these files is H&R Block Tax Software 2015.
The main disadvantage of the .T15 format is its extreme vendor lock-in and strict version dependency. The file contains heavily obfuscated Personally Identifiable Information (PII). You cannot open a .T15 file in a web browser, a standard document editor like DOCX, or even newer versions of H&R Block software without dedicated import workflows. Finding a working, authentic copy of the 2015 executable years after the filing deadline is extremely difficult, making long-term storage of just the .T15 file a major risk.
The best conversion target for a .T15 file is a standard PDF document. Converting to PDF provides a universally accessible, static record of your tax return that is essential for IRS audits or mortgage applications. However, this conversion typically must happen within the original software.
Because this is a closed, proprietary format, standard online converters fail to process it. They do not possess the proprietary algorithms required to decode the tax data and map it accurately to official tax forms. While full extraction requires the original 2015 software, our deep-scan analysis can inspect the raw file to verify its integrity and detect any unencrypted text strings or embedded metadata.
Convert.Guru analyzes your T15 file, detects the exact format, and lets you read the text inside.
If you want to convert T15 file to XLS, XLSX, XLSM, XLSB, ODS, CSV, TSV, TAB, DIF, SLK, WK1 or WK3, you can use H&R Block 2015 or similar software from the "Tax Return Data Storage" category. In the File menu, look for Save As… or Export….
To convert WQ1, XLSM, NOTES, QPW, WK3, WB2, WKS, XLSB, 123, XLS, WB1 or XLSX files to T15, try H&R Block 2015 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 T15 converter.
