You don't reference table1 inside the trigger. Use the inserted pseudo table to get the "after" values. Also remember that an update can affect multiple rows.

So replace your current update statement with

UPDATE table2
SET    table2.annualyear = inserted.intannualyear
FROM   table2
       JOIN inserted
         ON table2.id = inserted.id
