Try this

SQL

SELECT T3.EmpId,T3.PayId,Table2.PayAmount,T3.PaidAmount FROM
(SELECT EmpId,PayId,SUM(PaidAmount) AS PaidAmount
FROM Table3
GROUP BY EmpId, PayID) AS T3
INNER JOIN Table2
ON Table2.PayId=T3.PayId

Output

EmpId       PayId       PayAmount   PaidAmount
----------- ----------- ----------- -----------
1           1           1000        600
2           1           1000        1000
1           2           2000        1000
2           2           2000        2000

Check your sample output, it seems not correct.

Well, With regarding your comments, I assumed each employee join with each PayID. Therefore we have to use CROSS JOIN for that

SQL

SELECT Table1.EmpId,Table1.EmpName,Table2.PayId,Table2.PayAmount,ISNULL(PaidAmount,0)AS PaidAmount
FROM Table1
CROSS JOIN Table2
LEFT OUTER JOIN 
(SELECT EmpId,PayId,SUM(PaidAmount) AS PaidAmount
FROM Table3
GROUP BY EmpId, PayID) AS T3
ON T3.PayId =Table2.PayId AND T3.EmpId = Table1.EmpId
WHERE Table2.PayId=1

you will get hte following output

EmpId       EmpName PayId       PayAmount   PaidAmount
----------- ------- ----------- ----------- -----------
1           A       1           1000        600
2           B       1           1000        1000
3           C       1           1000        0

Please check your sample output, pay amount of EmpId 2 is not correct. It should be 1000 if you pass PayID=1
