Calculate fiscal year in SQL Server

Question

How would you calculate the fiscal year from a date field in a view in SQL Server?

Answer 1

CASE 
  WHEN MONTH(Date) > 6 
   THEN YEAR(Date) + 1
   ELSE YEAR(Date)
  END AS [FISCAL YEAR]

In this case, Fiscal Year starts on 7/1. This is the simplest solution out there.

Answer 2

Here's my version which returns fiscal year as FYyyyy - fiscal year begins 7/1

i.e. 6/1/2015 -> FY1415, 7/1/2015 -> FY1516

String functions could be better...

        CREATE FUNCTION [dbo].[FY](@DATE DATETIME)
        RETURNS char(6)
        AS
        BEGIN
            DECLARE @Answer     char(6)
            SET @Answer =    
            CASE WHEN MONTH(@DATE) < 7 
                 THEN 'FY' + RIGHT(CAST(YEAR(@DATE) - 1 AS VARCHAR(11)), 2) + RIGHT(CAST(YEAR(@DATE) AS VARCHAR(11)), 2) 
                 ELSE 'FY' + RIGHT(CAST(YEAR(@DATE) AS VARCHAR(11)), 2) + RIGHT(CAST(YEAR(@DATE) + 1 AS VARCHAR(11)), 2) END
            RETURN @Answer
        END

Answer 3

    declare 
@InputDate datetime,
@FiscalInput varchar(2),
@FiscalYear varchar(4),
@FiscalMonth varchar(2),
@FiscalStart varchar(10),
@FiscalDate varchar(10)

set @FiscalInput = '10'
set @InputDate = '1/5/2010'
set @FiscalYear = (select 
                    case 
                    when datepart(mm,@InputDate) < cast(@FiscalInput as int)
                        then datepart(yyyy, @InputDate)
                    when datepart(mm,@InputDate) >= cast(@FiscalInput as int)
                        then datepart(yyyy, @InputDate) + 1
                        end FiscalYear)


set @FiscalStart = (select @FiscalInput + '/01/' + @FiscalYear)

set @FiscalDate = (select cast(datepart(mm,@InputDate) as varchar(2)) + '/' + cast(datepart(dd,@InputDate) as varchar(2)) + '/' + @FiscalYear)
set @FiscalMonth = (select 
                    case 
                    when datepart(mm,@InputDate) < cast(@FiscalInput as int)
                        then 13 + datediff(mm, cast(@FiscalStart as datetime),@InputDate)
                    when datepart(mm,@InputDate) >= cast(@FiscalInput as int)
                        then 1 + datediff(mm, cast(@FiscalStart as datetime), @FiscalDate)
                        end FiscalMonth)    

select @InputDate as Date, 
cast(@FiscalStart as datetime) as FiscalStart, 
dateadd(mm, 11,cast(@FiscalStart as datetime)) as FiscalStop,
cast(@FiscalDate as DateTime) as FiscalDate,
@FiscalMonth as FiscalMonth, 
@FiscalYear as FiscalYear

Answer 4

I just realized that the marked answer by Brett Veenstra is wrong. Shouldn't The FY should be calculated like this?:

CREATE FUNCTION dbo.fnc_FiscalYear(
    @AsOf           DATETIME
)
RETURNS INT
AS
BEGIN
    DECLARE @Answer     INT
    IF ( MONTH(@AsOf) < 9 )
        SET @Answer = YEAR(@AsOf) 
    ELSE
        SET @Answer = YEAR(@AsOf) + 1
    RETURN @Answer
END;

Answer 5

Here is the dynamic code for UK,

You can work around based on different needs,

DECLARE @StartDate DATETIME

DECLARE @EndDate DATETIME

SET @StartDate = DATEADD(dd, 0,
    DATEDIFF(dd, 0,
        DATEADD(mm, - (((12 + DATEPART(m, getDate())) - 4)%12), getDate()) -
    datePart(d,DATEADD(mm, - (((12 + DATEPART(m, getDate())) - 4)%12),
        getDate() )) + 1 ))  

SET @EndDate = DATEADD(SS, -1, DATEADD(mm, 12, @StartDate))

SELECT @StartDate, @EndDate

Answer 6

DECLARE 
@StartDate DATETIME,
@EndDate DATETIME

if month(getdate())>3
Begin
        set  @StartDate=   convert(datetime, cast(year(getdate())-1 as varchar) + '-4-1')
        set @EndDate= convert(datetime, cast(year(getdate())  as varchar) + '-3-31')

end

else   
begin          
        set @StartDate= Convert(datetime, cast(year(getdate()) - 2 as varchar) + '-4-1')
        set @EndDate= convert(datetime, cast(year(getdate())-1 as varchar) + '-3-31')
end


select @StartDate, @EndDate
