Accurate, CPA-prepared federal corporate income tax returns for U.S. C corporations, reconciled to financial statements, supported by audit ready documentation, and filed without exposure to missed disclosures or avoidable penalties.
TYM Business Consulting provides Form 1120 corporate tax preparation for C corporations across the United States, with particular experience in foreign owned corporations, multi state operations, and complex book to tax reconciliation.
A federal corporate return is not a standalone filing. It is the downstream product of the year end close, and its accuracy depends directly on the quality of the underlying financial records. For corporations with foreign ownership, multi state activity, or material book to tax differences, accurate Form 1120 preparation reduces IRS examination exposure and preserves defensible filing positions.
A complete, CPA prepared Form 1120 engagement built on documented reconciliation, verified disclosures, and audit ready support.
✓ Form 1120 federal corporate tax return with all required schedules
✓ Book-to-tax reconciliation (Schedule M-1 or M-3) tied to financial statements
✓ Tax depreciation schedules (MACRS, Section 179, bonus depreciation)
✓ Foreign disclosure forms where required (Forms 5471, 5472, 8992, 1118)
✓ Tax attribute tracking (NOLs, credits, carryforwards)
✓ Estimated tax payment calculations for the following year
✓ Return support file with full documentation for IRS review
Form 1120 is the U.S. federal income tax return for C corporations. It establishes the corporation’s federal tax liability, determines taxable income, and drives estimated tax payment obligations.
For corporations with multi state operations, related party transactions, depreciation differences, deferred compensation, or foreign ownership, the gap between book income and taxable income can be material and must be properly documented.
Permanent and temporary book to tax differences must be identified, quantified, and disclosed through Schedule M 1 or Schedule M 3.
Errors in Form 1120 are not merely technical. They create direct IRS exposure, including penalties, audit triggers, and positions that may be difficult to defend under examination.
TYM prepares Form 1120 from a documented book to tax reconciliation, starting with the year end close package and building a return support file that ties each figure in the return back to the underlying financial records.
The result is a return that is internally consistent, defensible, and audit ready.
Missing Form 5472
$25,000 automatic penalty per form and increased IRS scrutiny of related party transactions.
Missing Form 5471
$10,000 penalty per controlled foreign corporation, often compounded annually until filed.
Undocumented book to tax reconciliation
A Schedule M 1 or M 3 that does not tie to the general ledger creates immediate examination exposure.
Inconsistent depreciation
When fixed assets do not reconcile between Schedule L and Form 4562, the return is more likely to be reviewed.
Officer compensation gaps
Schedule E amounts that are not supported by payroll records may raise compensation issues in closely held corporations.
Carryforward attributes not tracked
NOL or capital loss claims without origin year support may be disallowed on examination.
The IRS targets returns with gaps, inconsistencies, or missing required disclosures.
This engagement is typically relevant for:
Clients often engage TYM when one or more of the following applies:
A Miami-based technology company with a 40% foreign shareholder filed Form 1120 for three consecutive years without filing Form 5472, despite reportable related party transactions with the foreign parent.
When the IRS issued a notice requesting the missing forms, the corporation faced automatic penalties of $25,000, per year, for a total exposure of $75,000.
TYM prepared the delinquent Form 5472 filings, built transaction schedules tied to general ledger detail, submitted reasonable cause explanations, and coordinated the penalty abatement process.
Result: penalties reduced to $25,000 for one year
This was not a complex tax issue. It was a missed disclosure obligation with a significant cost.
Review of trial balance, financial statements, and general ledger. Issues identified before tax preparation begins.
Identification and documentation of all permanent and temporary differences that form the basis for Schedule M 1 or M 3 and ensure the return ties to the financials.
Preparation of tax depreciation schedules under MACRS, including Section 179 and bonus depreciation, while maintaining consistency with the fixed asset records.
Complete Form 1120 with all required schedules and disclosures, including foreign reporting where applicable.
Tracking of NOLs, capital losses, and credits across years to preserve tax benefits.
Calculation of next year’s estimated tax payments to reduce underpayment risk.
A full documentation package that ties the return to the underlying records and supports future IRS review or correspondence.

Federal corporate tax return fees depend on the confirmed scope of the engagement, including entity complexity, ownership structure, foreign components, multi state activity, fixed asset volume, and the condition of the year end close package.
Typical Form 1120 engagements start at $2,500 for straightforward domestic C corporations with clean year end financials and no foreign components.
A single entity domestic corporation with a clean close is materially different from a corporation with foreign subsidiaries, a foreign parent requiring Form 5472 disclosure, multi state activity, and NOL carryforwards requiring Section 382 analysis.
TYM structures fees based on confirmed scope after the initial filing assessment, not on a generic flat fee.
