Putting It Together

The architecture assembles into a sequence, each step triggered by the size and trajectory of the business:

1.
Confirm the activity is a business, not a hobby — keep books, separate finances, and operate to make a profit.
2.
Start as a sole proprietor or single-member LLC; treat the LLC as liability protection, not a tax strategy.
3.
When net profit clears roughly $80,000 to $100,000, model the S-corporation election to cut self-employment tax — and set a reasonable, documented salary.
4.
Use that salary to satisfy the IRC §199A wage test, and watch the SSTB thresholds.
5.
In a high-tax state, elect the pass-through entity tax before the deadline to deduct state tax above the SALT cap.
6.
Implement an accountable plan, use the Augusta rule with documentation, and fund a Solo 401(k).
7.
If the business is built for a venture-scale exit, incorporate as a C-corporation early to start the IRC §1202 clock — the eventual exclusion is worth the interim double taxation.
