Answer
The lewis structure is shown in the picture.
Work Step by Step
1) Draw the structure in the sequence shown in the formula.
2) Count the number of valence electrons involved in the bonding, which is 18. There should be 1+1+1+4+6+6+4+1+1+1= 26e. Make a one more bond between S and O. now there are 20 e.
3) Since O,C, H have already made the max bonds possible, place the remaining electrons as lone pairs, two on O and one on S.
4) Now count the valence electrons, it should be 26e.
