Including MTD And YTD Figure With A Daily Figure

Hello,
I have a query that returns a daily revenue figure. The query is as follows:

SELECT top 1000
ds.AcctCode,
ds.TxnDate,
SUM(isnull(ds.FuelFee,0)) + SUM(isnull(ds.CashFee,0)) + SUM(isnull(ds.ScFee,0)) AS TotalDailyRevenue,
--"MTD" = ?,
--"YDT" = ?,
ps.TC,
CASE
WHEN ps.Proj = 100 THEN 'New Account'
WHEN ps.Proj = 200 THEN 'Current Account'
END AS ProjStatus,
ps.FSR,
ps.SubmitRep1

FROM
TxnRptg.dbo.tbl_DailySummary ds
INNER JOIN SalesData.dbo.tbl_CYProcessedSales ps
ON ds.AcctCode = ps.Acct

WHERE
MONTH(ds.TxnDate) = 1
AND
Proj IN (100,200)
AND TC = 'HV'

GROUP BY
ds.AcctCode, ds.TxnDate, ps.TC, ps.Proj, ps.FSR, ps.SubmitRep1

ORDER BY
ds.AcctCode, ds.TxnDate

--*********************************

TxnDate represents a single day of the month. How can I include MTD so that the dates for the revenue total are from DATEADD(mm, DATEDIFF(mm,0,getdate()), 0) (beginning of current month) to TxnDate, and YTD so that the revenue totals are from DATEADD(yy, DATEDIFF(yy,0,getdate()), 0) (beginning of the current year) to TxnDate?


Thank you for your help!
