That depends on the force field you want to use.  There are parameters for 
sulfate in all of the Gromos force fields, but I can't comment on their 
suitability.  You should also not just pick one of these because it happens to 
already exist in order to make your life easy.

Check the literature for suitable parameters, otherwise have a look at 
http://www.gromacs.org/Documentation/How-tos/Parameterization and be prepared 
for a lot of work.
