We pulled the cap worksheets, walked the officer through what they were certifying, and got it filed the same day. The return cleared. That sprint is why this guide exists.
Key takeaways
- Schedule Q is the borrower’s signed certificate that a loan from your IC‑DISC qualifies as a producer’s loan, and it must be attached to Form 1120‑IC‑DISC.
- You certify two caps, the export‑related assets limitation and the increased‑investment requirement, then you sign under penalties of perjury. The form does not ask for principal, rate, or maturity. Keep those in your loan file.
- The return is due the 15th day of the 9th month after year end, with no extensions. For a calendar 2025 IC‑DISC, the due date is September 15, 2026.
- Mail Form 1120‑IC‑DISC with Schedule Q to the IRS Service Center listed for this return, Kansas City, MO 64999, or use a designated private delivery service with proof.
- A qualifying producer’s loan must be made out of accumulated DISC income, evidenced by a written obligation with a stated maturity of 5 years or less, carry a producer’s loan legend, and satisfy the two Schedule Q caps.
What Schedule Q is, and why it matters
Schedule Q, Borrower’s Certificate of Compliance, is a one‑page form the borrower signs. It certifies the two statutory limits that define how much producer’s loan can qualify this year. The IC‑DISC attaches that signed page to its annual Form 1120‑IC‑DISC. In an exam, Schedule Q is the IRS‑approved way to prove the borrower attested to the math behind those limits.
Think of Schedule Q as the borrower’s promise that your producer’s loan checks the two caps. Your note and your workpapers prove it, the certificate says it.
Who must file Schedule Q, and when
- File Schedule Q for any tax year your IC‑DISC makes a producer’s loan or has one outstanding. The borrower signs it, and you attach it to that year’s Form 1120‑IC‑DISC. It is not filed on its own.
- Due date follows the return, the 15th day of the 9th month after the IC‑DISC’s year end. There is no extension for this return. If the date lands on a weekend or holiday, use the next business day.
Where to mail the package
The IRS lists a specific address for Form 1120‑IC‑DISC. Mail to Department of the Treasury, Internal Revenue Service Center, Kansas City, MO 64999, or use an IRS‑designated private delivery service and keep tracking proof of timely filing.
What actually counts as a producer’s loan
The regulations spell out a checklist that your note and facts must meet for producer’s loan status:
- The loan is made out of accumulated DISC income, measured when the loan is made.
- It is evidenced by a written obligation with a stated maturity not over 5 years.
- The obligation bears a legend designating it as a producer’s loan.
- The borrower is engaged in the United States in making export property.
- The loan passes the export‑related assets limitation and the increased‑investment requirement.
- For related parties, interest is at an arm’s‑length rate under section 482.
Two good things happen when you get this right. The loan is a qualified export asset for the DISC’s 95 percent asset test, and the interest is a qualified export receipt.
A helpful nuance most teams miss
The regulations say you do not have to trace producer’s loan proceeds to a specific asset. Your binder still needs to prove the caps, but you are not chasing serial numbers for a machine.
The two Schedule Q caps in plain English
Schedule Q asks the borrower to certify two limits. Your workpapers do the math, the officer signs the form.
- Export‑related assets limitation. Start with beginning‑of‑year U.S. plant, equipment, and supporting production facilities, add property held for sale or lease, add all prior U.S. section 174 research since 1971. Multiply by the ratio of export sales to total sales over the prior three taxable years. That number caps the borrower’s total producer’s loans outstanding when a new loan is made.
- Increased‑investment requirement. For the tax year of the loan, take the year‑over‑year increase in those production assets, then add current‑year U.S. section 174 research. Producer’s loans made during the year qualify only up to that increase.
Quick example you can scan
Assume the borrower’s beginning‑of‑year balances show: plant and equipment 12,000,000, property held for sale 8,000,000, and cumulative U.S. research 2,000,000. Over the last three taxable years, export sales were 40 percent of total.
- Export‑related assets limitation, 12,000,000 + 8,000,000 + 2,000,000 equals 22,000,000. Multiply by 40 percent, cap A equals 8,800,000.
- Increased‑investment requirement, this year the asset base rose by 3,000,000 and section 174 spend is 500,000, cap B equals 3,500,000.
Your eligible producer’s loans for the year are limited to the lower cap, here 3,500,000.
The note package, lock the legal details
Even though Schedule Q does not ask for the terms, your note must meet the regulatory features that make the loan qualify.
- Written evidence of indebtedness with a stated maturity date of 5 years or less from the loan date. Extensions or renewals create a new loan that must still meet the 5‑year rule.
- A legend on the obligation, for example, “This obligation is designated a producer’s loan within the meaning of section 993(d) of the Internal Revenue Code.”
- The loan must be made out of the IC‑DISC’s accumulated DISC income at the time of the advance, so keep a monthly schedule that proves the balance.
- If borrower and DISC are related, document an arm’s‑length interest rate under section 482. Keep a short pricing memo.

Form content and regulatory requirements.
Step by step, completing Schedule Q without drama
- Confirm the loan meets the producer’s loan definition in the regulations.
- Build the two cap worksheets and have the borrower’s officer review them.
- Enter the IC‑DISC and borrower identification on Schedule Q, exactly as shown on the return.
- Obtain the officer’s signature and date under penalties of perjury. File the signed page with the return copy.
- Attach Schedule Q behind the 1120‑IC‑DISC in the package you mail.
A single PDF binder per borrower, note plus legend, pricing memo, accumulated DISC income rollforward, both cap sheets, and the signed Schedule Q, will cut your review time to minutes.
Filing mechanics you should confirm each year
Due date
The IC‑DISC return is due the 15th day of the 9th month after the IC‑DISC’s year end. There is no extension for this return. Calendar 2025 IC‑DISCs are due September 15, 2026. File the next business day if the date lands on a weekend or federal holiday.
Assembly order and identifiers
The IRS tells filers to attach all schedules and forms after the last page of Form 1120‑IC‑DISC, schedules first in alphabetical order, forms next in numerical order. Put the IC‑DISC name and EIN on each attachment. That makes Schedule Q easy to find during processing or exam.
Mailing addresses and private delivery services
The IRS keeps a list by return type. For Form 1120‑IC‑DISC, mail to the Kansas City, MO 64999 Service Center address shown on the “Forms beginning with 1” page. If you use a designated private delivery service, use the street address list and keep tracking proof.
E‑file reality for 1120‑IC‑DISC
IRS MeF supports many corporate forms, but industry guidance is clear that Form 1120‑IC‑DISC is not processed as a standalone MeF return. Many firms still paper‑file this form and retain mailing proof. Check your software, verify acceptance with your vendor, and plan to mail if MeF is unavailable.
Five‑minute reviewer pass, what I look for
- The note shows a stated maturity of 5 years or less and the producer’s loan legend appears in the body or near the signature block.
- A one‑page schedule proves the loan was made out of accumulated DISC income when advanced.
- The export‑related assets limitation and increased‑investment worksheets tie to the GL, fixed asset rollforwards, and section 174 detail.
- If related, there is a short memo supporting an arm’s‑length interest rate under section 482.
- Schedule Q is signed and dated by an authorized officer and is attached behind the return.
Common errors to avoid
- Putting loan terms on Schedule Q. The form never asks for principal, rate, or maturity. Keep those in your binder.
- Missing the 5‑year maturity or the legend on the note. Both are explicit.
- Forgetting the accumulated DISC income test at the time of advance. Build a monthly rollforward.
- Skipping Schedule Q because the loan was small. Any qualifying producer’s loan means a signed Schedule Q.
Schedule Q vs. Schedules P and K, what each one covers
- Schedule Q, a one‑page borrower certification that a loan qualifies as a producer’s loan by meeting the two limits. Attach it when producer’s loans exist.
- Schedule P, the computation of taxable income used to set commission or transfer price between a related supplier and the IC‑DISC, one per transaction set.
- Schedule K, the shareholder statement for actual and deemed distributions, including deferred DISC income.
Why it matters in practice
A clean Schedule P supports your pricing position, Schedule K informs owners, and Schedule Q protects the qualified asset status of producer’s loans you rely on to keep the 95 percent tests intact. Those pieces reduce the odds of an interest‑charge surprise or a qualification issue.
How producer’s loans affect IC‑DISC status and owner cash cost
- A valid producer’s loan is a qualified export asset. Interest on it is a qualified export receipt. Those two facts help the DISC maintain its 95 percent asset and receipts profile.
- IC‑DISC shareholders with deferred income generally owe an annual interest charge on the deferred tax under section 995(f), computed on Form 8404. Producer’s loans do not eliminate that charge, they help you keep the DISC qualified.
Controlled group considerations in one page
If your borrower is part of a controlled group, the regulations permit an election to aggregate amounts for the two tests across eligible domestic members. Draft the election, attach it to the return for the first applicable year, and retain it in your binder. Keep a worksheet showing how each member’s assets and receipts feed the caps.
Compliance note and date check
This guide reflects IRS instructions revised in December 2025 and the Schedule Q form as of September 2016, current as of February 20, 2026. Always confirm the latest instructions and the IRS where‑to‑file page before you submit.
If your facts are close to a cap, put the calculations in front of the signing officer before quarter end. That habit saves awkward year‑end rewrites.
A practical workflow your team can reuse
- In planning season, identify the potential need for producer’s loans and sketch the two caps with last year’s numbers.
- Draft note terms that satisfy the 5‑year maturity and include the producer’s loan legend. Price interest and save a short section 482 memo if related.
- Build a monthly accumulated DISC income rollforward and keep it current.
- Assemble a borrower binder, note plus legend, pricing memo, both cap worksheets, and a signature‑ready Schedule Q.
- At return prep, refresh the cap math, obtain the officer’s signature, attach Schedule Q right behind the return, and mail with tracking.
FAQs you can scan in a minute
What exactly is Schedule Q?
It is the borrower’s signed certificate that a loan from an IC‑DISC qualifies as a producer’s loan by meeting the export‑related assets limitation and the increased‑investment requirement. You attach it to Form 1120‑IC‑DISC.
Does Schedule Q list principal, rate, or maturity?
No. The form only identifies the parties and captures the two certifications with a signature. Keep loan terms and support in your workpapers.
Do I have to trace proceeds to a specific machine or batch?
No. The regulations say producer’s loan proceeds do not have to be traced to a specific asset. Your binder still needs solid cap calculations.
Can I e‑file Form 1120‑IC‑DISC?
Most firms mail this return. IRS MeF supports many 1120 family forms but industry guidance shows 1120‑IC‑DISC is not processed as a standalone MeF return. Verify with your software and plan to mail with proof if needed.
Where do I mail it?
Use the IRS “forms beginning with 1” page. For Form 1120‑IC‑DISC, the address is Kansas City, MO 64999. If you use a private delivery service, use the IRS PDS street address list and keep tracking.
