I can only hope that your goal is to help automate the process while reminding tax preparers of options to help their clients. Don't you think more preparers would like to know an option to lower the bracket is available? Lets pretend it's March or April. Do you think it would help then? I've tried to test the system and sometimes the number doesn't lower the bracket. Wouldn't it be nice if the system said if you add exactly $2345 to an IRA it would lower your bracket to a certain %? The easier the better. This is easy for you guys. Make it easy for us!
