- Payroll mindset, estimates, SE tax, basis, 83(b), state filings
- Exact fixes + onboarding checklist
1. The “I’m Still an Employee” Trap
No more auto-withholding. K-1 income, no W-2 safety net. Some fringes become taxable.
2. Quarterly Pay-In Panic
Estimated payments now on you. Safe harbor or annualized — miss timing, pay penalties.
3. Self-Employment Tax Surprise
Guaranteed payments + ordinary income hit SE tax. Distributions usually don’t.
4. Basis vs. Capital Confusion
Track outside basis for loss limits and debt allocation. Capital account ≠ basis.
5. Missing 83(b) Election
Profits interest? File 83(b) within 30 days or pay ordinary income on future appreciation.
6. State Filing & PTE Blind Spots
New states from partnership activity + PTE elections/payment deadlines vary.

Frequently Asked Questions
1) Do partners get withholding?
Rarely — you’re responsible for estimates. Some firms withhold voluntarily.
2) How to avoid underpayment penalties?
Safe harbor (100%/110% prior-year) or annualized income method.
3) Guaranteed payments — good or bad for SE tax?
They trigger SE tax but create basis for losses. Balance carefully.
4) What’s the 83(b) deadline?
30 days from grant. No extensions. File with IRS + copy to partnership.
5) Why care about Section 754?
Steps up inside basis after purchase → extra depreciation/amortization over years.
