Answer
The lewis structure is shown in the picture.
Work Step by Step
1) Draw 4 O around S and then put one H on each side.
2) Count the number of valence electrons involved in the bonding, which is 12. There should be 1+6+6+6+1+6+6 = 32e. Make a one more bond between each S and O. Now there are 16 e.
3) Since O,C,H,S have already made the max bonds possible, place the remaining electrons as lone pairs, two on each O.
4) Now count the valence electrons, it should be 32e.
