a calendar quarter is typically defined as every 3 months (Jan-Mar, Apr-Jun, Jul-Sep & Oct-Dec). The IRS has defined it for tax purposes as 3 months, 2 months, 3 months & 4 months:
The Investing Activity report shows a quarterly breakdown of activity (Dividends & Realized Gains) and I have been trying to use this to pay estimated taxes for the year based on my accounts activity.
Does anyone have any suggestions or is there a way to show this information in the IRS period requirements? or do I manually set dates and look at it simplistically? (I like the column view by Quarter, but it is off when looking at IRS payment dates).
