Step-by-Step: Form 1120 Filing Process
Preparation (Before E-File)
Gather all documents:

- Form 1099-MISC from Family Dollar
- Bank statements for all months

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