More flexible fringe benefits
S-Corp considerations:
Pass-through taxation eliminates double taxation

QBI deduction generally not available for rental income
Consult CPA before switching
7. Charitable Contributions (if applicable)
C-Corps can deduct charitable contributions up to 10% of taxable income
Requires taxable income to utilize (not useful if NOL)
Phase 5: 1099-MISC Reconciliation for NNN Properties
The Pass-Through Pattern (Critical Insight)
For NNN properties, 1099-MISC Box 1 commonly includes property tax proration that the landlord pays to the county and the tenant reimburses. This is a pass-through with net zero tax impact:
Tax reimbursement → income (included in gross rents on Form 1120 Line 5)
Property tax paid → expense (deducted on Schedule A Line 5)
Net effect: $0 on taxable income
This means even if the 1099 "over-reports" by including tax proration, filing can proceed while awaiting payer confirmation. The discrepancy is cosmetic, not financial.
Reconciliation Workflow
Get 1099-MISC from payer
List all known payments: rent months, insurance reimb, HOA reimb, tax reimb
Calculate expected total = rent + reimbursements received in calendar year
Compare gap to property tax proration: total_tax / 12 × months_owned
If gap matches tax prorate → it's a pass-through, net zero impact
Email payer for itemized breakdown (good practice, NOT blocking)
File with 1099 amount (simplest) or actual income with explanatory statement
