I wrote a few scripts to help with doing my US Federal taxes this year. To do things like estimating sales tax and parsing information from 1099 forms. I wanted to post this code on GitHub in case someone else might find it useful. However, I'm worried that since I am not a CPA, this could be illegal. I was planning to release it under MIT because of this clause:

Which seems like it would cover my liability in case there are any errors with the calculations. I'm concerned though that although my code isn't actually completing any forms, I could be breaking some laws or regulations regarding taxes by posting it online.
Is anyone aware whether or not I am allowed to release tax-related scripts open source? Do I need to add any additional disclaimers?
