I always file for an automatic 6 month extension and typically file my tax returns in August or September ahead of the October 15th deadline. One has to make an estimate of tax due by April 15th, but no reason is required for the extension. Of course, if more tax is due when one ultimately files, then an interest penalty is assessed.
The extension allows me more time and is practical for the usual amended 1099's that I get as late as May or June.
