Partnerships and Corporations

The following are 25 Tax-Smart Moves for Partnerships and Corporations (S-Corps & C-Corps) – so you legally pay less and keep more:

Entity taxes are full of “it depends.” The right move for a partnership can be wrong for an S-corp; a C-corp strategy can backfire for pass-through owners. Use this checklist to spot savings—and let RDA Tax Services turn them into an intentional plan.

1. Pick (and re-pick) the right entity.
   Profits, owner salaries, benefits, and exit plans drive whether you should be a partnership, S-corp, or C-corp. Reevaluate yearly—tax laws and your margins change.
2. S-corp reasonable compensation.
   Owners who work in the business must take reasonable W-2 wages before S-corp distributions; pay too little and you risk payroll tax penalties—too much and you kill QBI savings.
3. Partnership compensation design.
   Swap some guaranteed payments (always taxable, reduce QBI) for priority allocations or targeted distributions where appropriate to preserve QBI and flexibility.
4. Track partner/shareholder basis.
   Basis controls loss deductions and tax-free distributions. Keep tight schedules for outside basis (partners) and stock/debt basis (S-corp) to avoid surprise taxes.
5. Leverage the QBI (199A) deduction (pass-throughs).
   Owners may get up to 20% off qualified business income, subject to wage/UBIA tests and SSTB limits. Optimize W-2 wages, asset placement, and owner comp to protect it.
6. C-corp vs. pass-through rate modeling.
   C-corp 21% looks tempting—until shareholder-level tax on dividends. Model double tax vs. pass-through/QBI across 3–5 years (and at exit).
7. Exploit PTE (pass-through entity) SALT workarounds.
   Many states let partnerships/S-corps pay state tax at the entity level, creating a federal deduction that bypasses the individual SALT cap.
8. Adopt an accountable plan.
   Reimburse owners/employees for business expenses tax-free with proper substantiation. Without a plan, the same dollars can become taxable wages.
9. Max out retirement plans.
   Consider safe-harbor 401(k) or a cash balance plan for large deductions. S-corps need enough W-2 comp to support contributions; partnerships can allocate flexibly.
10. Self-employed health + 2% S-corp rules.
    For 2% S-corp owners, premiums must be added to wages (no FICA) to unlock the Self-Employed Health Insurance deduction at the individual level.
11. Section 179 and bonus depreciation.
    Match big write-offs to profitable years; mind business-use percentages, SUV caps, and related-party purchases.
12. Cost segregation on buildings.
    Identify shorter-life components in owned real estate to accelerate depreciation and boost cash flow.
13. Timing income & expenses (method matters).
    On cash method, defer receipts and accelerate payables; on accrual, manage year-end cut-offs and reserves. Consider method changes or the small-taxpayer exception to avoid UNICAP.
14. R&D credit and Section 174.
    Claim the R&D credit where eligible and plan for the current law that capitalizes and amortizes R&D—timing and documentation are everything.
15. Hiring & wage credits.
    Screen for the Work Opportunity Tax Credit (WOTC), FICA tip credit (restaurants), and targeted state credits. Paperwork must be done before hire in some cases.
16. Meals, travel, and entertainment rules.
    Most business meals 50% (some 100% exceptions), entertainment nondeductible. Label receipts with who/why to keep the deduction.
17. Interest tracing and debt structure.
    Deductibility depends on use of funds. Label borrowings and intercompany loans clearly; consider thin-cap and 163(j) limits for larger enterprises.
18. NOL strategy (C-corp vs. owners).
    NOLs have carryforward limits; coordinate owner wages/dividends (C-corp) or allocations (pass-through) so losses land where they produce the most value.
19. Sales/use tax, nexus & apportionment.
    Remote employees, inventory, or sales platforms can create multi-state nexus. Correct apportionment and registrations prevent penalties and overpaying.
20. S-corp E&P, AAA, and distribution ordering.
    If your S-corp has C-corp earnings & profits, distributions can become taxable dividends. Manage AAA and consider elections to control ordering.
21. Built-in gains (BIG) tax on S-corp conversions.
    Converted from C to S? Asset sales inside the BIG recognition window can trigger corporate-level tax. Plan holding periods and sale timing.
22. Intercompany pricing & documentation.
    Even small groups should price intercompany services/loans at arm’s length. Clean memos prevent reclassifications and headaches.
23. Owner real estate strategies.
    Consider separating operating entity and real estate (OpCo/PropCo) for liability and tax planning; set market rent, evaluate 199A and passive/active groupings.
24. Clean 1099s, W-9s, and worker classification.
    Misclassifying contractors risks back payroll taxes and penalties. Collect W-9s upfront and file 1099s on time to protect deductions.
25. Plan your exit early.
    Asset vs. stock sale, 338(h)(10) elections, QSBS (Section 1202) for C-corps, and earn-out structures can swing seven figures in tax. Start modeling well before you list.
