In my state, CPAs are prevented by law from making promises or implications about performance in the name of their firms. I will assume that any certifications that you, your employer's firm and your boss have lack such restrictions, but you should definitely check that kind of thing before you establish a new business name.
Personally I agree that all names OP has offered have 2 weaknesses:
1. They obscure more than they explain
2. Because they sound grand but unfocused, they seem unprofessional - like the vague scheme of an inexperienced beginner, not the straightforward name of an authoritative source of tax expertise (please don't take offense, I'm just saying how they sound to me)
If your focus is tax preparation for small businesses, and you are allowed to use a descriptive name such as the following, I would suggest instead something like:
3. Small Business Tax Preparation
4. (Name of My Town) Tax Prep
5. (Name of My Town) Business Tax Preparers
6. (Boss Name) Business Tax Specialists
7. In other words, some combination of place or person name, plus general business (tax), plus core focus (business, or perhaps preparation, or...)
If your focus is S incorporation and filing, AND descriptive names are allowed in your jurisdiction, possibly register and advertise a dba such as:
8. S Corp Specialists of (Your Town's Name)
ETA: Ok, I just re-read and finally realized that you plan for the blog to be separate somehow from the business you work for, even though you want to generate referrals to the business. I'm used to CPA rules in my state, where paid referrals are forbidden.
Assuming it's truly ok to write such a blog in your personal capacity and still generate referrals (I assume you'll acknowledge your dual role on your site), how about:
9. Tax Tips for (Name of Your Town or Region) Entrepreneurs
