The SEC has formally approved the use of the 2015 XBRL Taxonomy. While this has not yet been generally announced in a press release it is highlighted with a “New” label on the SEC’s XBRL page at:
Generally, when a new taxonomy is approved the SEC discontinues use of the oldest taxonomy. They usually allow the use of two taxonomies, the newest year and the next newest year. (The FASB publishes a new taxonomy every year and submits it to the SEC who after review approves it for use by companies).
Now that the 2015 Taxonomy is approved for use the next earliest year, 2014 is also allowed, and the year before that, 2013, will be discontinued soon. Currently, as we approach quarter end, the SEC is allowing the use of all three of these taxonomies, 2015, 2014 and 2013. Likely the 2013 taxonomy will be discontinued soon, so if you are still using the 2013 Taxonomy it will be time to update soon. You should monitor the approved taxonomies at:

As mentioned, the FASB is now responsible for maintaining the US GAAP Taxonomy. At the FASB’s webpage you can find out about their project to simplify the taxonomy. It would be hard to find anyone who would not support that project!

And, just in case you have not heard about them yet, you can also find several implementation guides for specific tagging issues at the FASB’s webpage also. Check out:

Hope all this helps, and as usual your thoughts and comments are welcome!
