SQL Date Range Syntax Assistance

I have the need to calculate a 'season to date' date range and add it to my query below. Our season runs as follows January thru Jun and July thru December so if the current month is August my output should be 07/01/2016 AS STDStartDate and 12/31/2016 AS STDEndDate

SELECT  DATEADD(wk, 0,
                DATEADD(DAY, 1 - DATEPART(WEEKDAY, GETDATE()),
                        DATEDIFF(dd, 0, GETDATE()))) AS WkStartDate ,
        DATEADD(wk, 1,
                DATEADD(DAY, 0 - DATEPART(WEEKDAY, GETDATE()),
                        DATEDIFF(dd, 0, GETDATE()))) AS WkEndDate ,
        DATEADD(mm, DATEDIFF(mm, 0, GETDATE()), 0) AS MthStartDate ,
        DATEADD(dd, -1, DATEADD(mm, DATEDIFF(mm, 0, GETDATE()) + 1, 0)) AS MthEndDate ,
        DATEADD(yy, DATEDIFF(yy, 0, GETDATE()), 0) AS YearStartDate ,
        DATEADD(yy, DATEDIFF(yy, 0, GETDATE()) + 1, -1) AS YearEndDate;

May be something like this. try this.
SELECT  DATEADD(wk, 0,
                DATEADD(DAY, 1 - DATEPART(WEEKDAY, GETDATE()),
                        DATEDIFF(dd, 0, GETDATE()))) AS WkStartDate ,
        DATEADD(wk, 1,
                DATEADD(DAY, 0 - DATEPART(WEEKDAY, GETDATE()),
                        DATEDIFF(dd, 0, GETDATE()))) AS WkEndDate ,
        DATEADD(mm, DATEDIFF(mm, 0, GETDATE()), 0) AS MthStartDate ,
        DATEADD(dd, -1, DATEADD(mm, DATEDIFF(mm, 0, GETDATE()) + 1, 0)) AS MthEndDate ,
        DATEADD(yy, DATEDIFF(yy, 0, GETDATE()), 0) AS YearStartDate ,
        DATEADD(yy, DATEDIFF(yy, 0, GETDATE()) + 1, -1) AS YearEndDate,
        CASE WHEN REPLACE(CONVERT(VARCHAR(5),GETDATE(),1),'/','') <= '0630' THEN '0101' ELSE '0701' END AS STDStartDate,
        CASE WHEN REPLACE(CONVERT(VARCHAR(5),GETDATE(),1),'/','') <= '0630' THEN '0630' ELSE '1231' END AS STDEndDate;

Sounds like a candidate for building your own SQL Server Calendar Table, where you can add logic for custom seasons like Fiscal Years here.  

That way instead of having to code a big honkin' expression every time you want to query season-to-date, just code it once when you build the table in order to populate season-specific columns.  Then you can do a simple JOIN in query expressions.
