2. **Missing Form 8825** — required for all rental real estate income
3. **Depreciation errors** — most common error on NNN returns
4. **Not reporting reimbursements** — they are taxable income
5. **Wrong tax year** — first-year short period (May 27 to Dec 31, 2025 for SKEstates)
6. **Missing M-1** — required when total assets or gross receipts > $250,000
7. **Not signing** — must be signed by authorized officer
8. **Not including state filing** — TX franchise tax due May 15
