Form 1120 (2016) Tax Year—IRS-Accurate Checklist
2016 Form 1120 Unique Context
Form 1120 (2016) introduced Schedule K, question 19, which requires disclosure of Forms 1042 and 1042-S payment obligations. The 2016 form maintains the $250,000 dual threshold (total receipts AND total assets) for Schedule L exemption and enforces the $10 million Schedule M-3 asset threshold. An alternative tax computation for qualified timber gains (held for 15 years or more) applies if the corporation has both a net capital gain and a qualified timber gain.
No pandemic-related or TCJA provisions affect 2016 filings; standard estimated tax rules, requiring a minimum threshold of $500 and quarterly IRC Section 6655 payments, apply.
Year-Specific Rules for 2016 Form 1120
No Economic Impact Payment reconciliation applies. ACA shared responsibility reporting does not apply to Form 1120 filers. Estimated tax required if total expected tax (less credits) reaches $500 or more; quarterly installments due 15th day of 4th, 6th, 9th, and 12th months using electronic funds transfer.
10-Step Form 1120 (2016) Filing Checklist
Step 1: Tax Year Verification
Confirm the corporation’s calendar year 2016 or fiscal year beginning 2016. Verify the incorporation date, EIN, and total assets at year-end as recorded on the books.
Step 2: Income Documentation
Gather gross receipts (line 1a), returns and allowances (line 1b), Form 1125-A (cost of goods sold, required if deduction claimed), dividend income (Schedule C), interest, rents, royalties, and other income items (lines 5–10).
Step 3: Officer Compensation and Payroll Reporting
Prepare Form 1125-E only if total receipts are $500,000 or more; report officer compensation (line 12) and wages (line 13); obtain all W-2 documentation.
Step 4: Deduction Documentation
Compile depreciation (Form 4562), charitable contributions (limited to 10 percent of taxable income with a five-year carryover), business interest expense deductions, and other deductions (lines 14–26). Gather records of business gifts (limited to $25 per recipient per year) and meal/entertainment expense records (50 percent limitation applies).
Step 5: Schedule L Threshold Test
Calculate total receipts (line 1a plus lines 4–10) and year-end total assets. If both totals are less than $250,000, Schedules L, M-1, and M-2 are not required; otherwise, complete all balance sheet and reconciliation schedules.
Step 6: Schedule M-3 Requirement Test
If total assets reportable on Schedule L equal or exceed $10 million at year-end, complete Schedule M-3 (net income reconciliation) instead of Schedule M-1; file Schedule M-3 and verify box 4 on Form 1120 page 1.
Step 7: Schedule C and Special Deductions
If the corporation received dividends, complete Schedule C, identifying dividend source corporations and percentages owned, and calculate the special deduction (line 29b); attach Form 1125-A if the cost of goods sold is claimed.
Step 8: Schedule K Questions
Answer all Schedule K (Other Information) yes-no questions, including new question 19: “Did the corporation during this tax year make any payments that would require it to file Forms 1042 and 1042-S under chapter 3 or chapter 4 of the Code?” Provide required information for 20-percent ownership tests, controlled group status, and NOL elections.
Step 9: Tax Computation and Estimated Tax Penalty
Complete Schedule J (Part I), calculating total tax (line 11); if the corporation has both net capital gain and qualified timber gain, determine whether the alternative tax under Section 1201(b)(2) applies. Calculate estimated tax: if total expected tax (less credits) is $500 or more, quarterly payments of equal installments are due; use Form 2220 to compute underpayment penalty if payments were insufficient; confirm electronic funds transfer used for all deposits.
Step 10: Signature and Assembly
Officer signs and dates Form 1120 under penalties of perjury. If a a paid preparer signed the return for a fee, obtain the preparer’s PTIN, signature, date, and check box authorizing an IRS discussion. Assemble schedules and forms in the following order per IRS instructions: Schedule N, Schedule D, Schedule O, Form 4626, Form 8050, Form 1125-A, Form 4136, Form 8941, Form 3800, then additional schedules in alphabetical order and additional forms in numerical order, with supporting statements and attachments last. See the IRS Where to File page for the 2016 Form 1120 paper-filing address, based on state and asset size.
2016 Line Changes
Schedule K, Question 19
This represents an added provision. The current year (2016) requires corporations to disclose whether they made payments requiring Forms 1042 and 1042-S filing (withholding on non-U.S. persons’ income).
Schedule J, Line 2 – Qualified Personal Service Corporation and Alternative Tax
This update represents a clarified provision. Current year (2016) instructions explain that for tax years beginning in 2016, if a corporation holds both net capital gain and qualified timber gain, the alternative tax computation under IRC Section 1201(b)(2) may apply; attach the calculation if an election is made.
