What IRS Form 1120-RIC (2018) Is For

Form 1120-RIC is the U.S. Income Tax Return for Regulated Investment Companies, used by mutual funds, REITs, and similar investment entities to report their income, gains, losses, deductions, and credits to the IRS (IRS Instructions for Form 1120-RIC (2018)). Only companies that qualify as regulated investment companies under strict income, asset diversification, and distribution requirements must file this specialized corporate tax return.

When You'd Use Form 1120-RIC for 2018 (Late or Amended Filing)

You would file a late or amended 2018 Form 1120-RIC if you received IRS notices about an unfiled return, discovered errors in your original filing, or need to claim additional deductions or credits. Late filing situations typically arise when RICs miss the original due date (15th day of the 4th month after tax year end) and face mounting penalties of 5% per month on unpaid taxes, up to 25% maximum (IRS Instructions for Form 1120-RIC (2018)). For amended returns, you generally have three years from the original filing date or two years from when you paid the tax to claim refunds or correct errors.

Key Rules Specific to 2018

The 2018 tax year brought significant changes due to the Tax Cuts and Jobs Act, including a flat 21% corporate tax rate replacing the previous graduated structure and elimination of the corporate alternative minimum tax (IRS Instructions for Form 1120-RIC (2018)). RICs also became subject to new Global Intangible Low-Taxed Income (GILTI) rules for controlled foreign corporation interests, requiring Form 8992 to be attached. Additionally, new business interest expense limitations under Section 163(j) may require filing Form 8990 unless meeting small business exceptions.

Step-by-Step (High Level)

• Gather tax transcripts from the IRS for 2018 to understand what they have on file and identify any discrepancies or missing information
  
  
• Complete the 2018 Form 1120-RIC using the correct year's form and instructions, not current-year versions, ensuring all income tests and distribution requirements are properly calculated
  
  
• Attach required schedules in the specified order including Schedule K (Form 1120), excise tax forms if applicable, and any supporting statements
  
  
• File by mail to the Ogden, Utah processing center (electronic filing may not be available for prior years) and consider certified mail for proof of delivery
  
  
• Keep complete copies of all filed documents, attachments, and proof of mailing for your records and potential IRS correspondence
  
  

Common Mistakes and How to Avoid Them

• Using wrong year forms - Always use the specific 2018 version of Form 1120-RIC and its instructions, not current-year forms which may have different requirements or line numbers
  
  
• Failing the 90% distribution test - Carefully calculate that dividends paid equal at least 90% of investment company taxable income; missing this disqualifies RIC status entirely
  
  
• Incorrect excise tax calculations - If subject to the 4% excise tax under Section 4982, ensure proper measurement periods and file Form 8613 separately for the calendar year
  
  
• Missing GILTI inclusions - Don't forget to include controlled foreign corporation income under new Section 951A rules and attach Form 8992 when required
  
  
• Asset diversification errors - Verify quarterly asset tests are met throughout the year, as failing even one quarter can disqualify RIC status
  
  
• Incomplete shareholder reporting - Ensure all dividend distributions are properly reported to shareholders and match amounts claimed on the return
  
  

What Happens After You File

The IRS typically takes 6-8 weeks to process paper-filed corporate returns, though late or amended returns may take longer due to additional review requirements. You may receive notices requesting additional documentation or questioning specific items on your return. If you owe additional taxes, consider setting up an installment agreement using Form 9465 to avoid collection actions. You have appeal rights if you disagree with IRS adjustments, starting with an informal conference with the examining agent's supervisor, and potentially proceeding to Tax Court if necessary.

FAQs

Can I still file my 2018 Form 1120-RIC in 2025?

Yes, you can file late returns for any year, though you'll face penalties of 5% per month on unpaid taxes up to 25% maximum, plus interest on both taxes and penalties (IRS Instructions for Form 1120-RIC (2018)).

What if I already lost my RIC status for 2018?

If you failed to meet income, asset, or distribution tests, you cannot use Form 1120-RIC and must file regular Form 1120 as a C corporation, potentially facing double taxation on distributed earnings.

How do I get my 2018 tax transcripts before filing?

Request transcripts online at IRS.gov, by phone at 800-908-9946, or by mailing Form 4506-T; allow 5-10 business days for online requests or 2-3 weeks for mailed requests.

Can I claim a refund on my 2018 amended return?

The three-year statute of limitations for 2018 refund claims ended in 2022 (based on original due date), so you generally cannot claim refunds unless you qualify for rare exceptions like bad debt deductions.

Do I need to amend my state returns too?

Most states require amended returns when you amend federal returns, especially for RIC pass-through items that flow to state calculations; check your specific state's requirements and deadlines.

What about the excise tax if I didn't distribute enough in 2018?

File Form 8613 separately for calendar year 2018 if you're subject to the 4% excise tax on undistributed income; this filing requirement exists even if no excise tax is actually due (IRS Instructions for Form 1120-RIC (2018)).

Should I hire a professional for late RIC filings?

Given the complexity of RIC rules, distribution calculations, and potential penalties, professional assistance is often worthwhile, especially for entities with significant assets or complicated investment structures.
