Many finance teams struggle with it because the inputs sit in different places: export records, supplier books and the IC-DISC's own ledger. This article is for Australian businesses, finance teams and advisers connected with U.S. export structures. Schedule P is a U.S. federal filing requirement, and Australian tax treatment must be reviewed separately.
Key Takeaways
- Schedule P documents pricing between an IC-DISC and its related supplier.
- Confirm qualified export transactions before any calculation.
- Method, workpapers and the main return must agree.
- Use the current IRS form, instructions and filing guidance.
What Is Schedule P and When Does It Apply?
Schedule P shows the computation supporting the transfer price or commission arising from transactions between an IC-DISC and a related supplier. Per the IRS Schedule P, it has three parts:
| Part | Function |
|---|---|
| Part I | IC-DISC taxable income: Section A computes combined taxable income (CTI); Sections B and C apply the 50-50 and 4% methods |
| Part II | Transfer price from the related supplier to the IC-DISC (buy-sell transactions) |
| Part III | IC-DISC commission from the related supplier (commission transactions) |
When Schedule P is relevant
It applies when a related supplier sells export property to the IC-DISC, or pays it a commission on qualifying export activity. Attach a separate Schedule P for each transaction, or for each permitted product or product-line group. Methods can cover sales, leases and services, subject to restrictions.
Do not complete Schedule P where pricing follows section 482. Check the current instructions to confirm which part fits your transaction.
Distinguishing Schedule P from other schedules
- Main Form 1120-IC-DISC: the IC-DISC information return itself.
- Schedule K: the shareholder's statement of IC-DISC distributions, including deferred DISC income.
- Schedule Q: the borrower's certificate for producer's loans.
- Schedule K-1: used by partnerships and S corporations, not by IC-DISC reporting.
Australian ownership, customers or operations do not by themselves establish eligibility. The transaction must meet the U.S. IC-DISC rules.
Prepare the Information Needed for Schedule P
Confirm the parties, structure and tax year
Before calculating, identify:
- The IC-DISC and the related supplier
- The ownership or control relationship
- The tax year and accounting method
- The nature of the export arrangement
Then collect the commission agreement or transfer-price agreement, intercompany invoices and any amendments. These show how the parties intended to price the transactions.
Build a complete export transaction file
Gather the evidence for each sale:
- Sales invoices and product descriptions
- Customer and destination details
- Shipping or delivery records and export documents
- Sales dates and currency information
- Proof of foreign use or destination
Then separate potentially qualifying receipts from domestic sales, returns, allowances, non-qualifying services and anything else that should stay out of the calculation.
Verify qualified export property and receipts
Two layers apply. The corporation must derive at least 95% of gross receipts from qualified export receipts, and qualified export assets must be at least 95% of asset basis, per the IRS instructions. Separately, each item of property must meet the export property conditions:
- Manufactured, produced, grown or extracted in the United States by someone other than a DISC
- No more than 50% of fair market value attributable to imported articles
- Held for sale or lease in the ordinary course for direct use, consumption or disposition abroad
A sale to a foreign customer is not automatically qualifying. Flag borderline items, such as assembly-only products or services, for specialist review. Failure to prove the destination test prevents qualification.
Allocate costs and preserve evidence
Identify direct production, acquisition, freight, selling and administrative costs, and allocate them under your chosen method. Where costs span export and domestic activity, or several product lines, document the allocation basis.
Build a trail from source documents to receipts, cost allocations, method, result and the Schedule P figures. Keep:
- Intercompany agreements and invoices
- Export and destination records
- Cost allocation schedules
- Supplier-to-IC-DISC reconciliations
Supporting records are usually retained for three years from the later of the due date or filing date, but remain required while material to tax administration. Basis records may be needed longer.
Calculate the Transfer Price or Commission
Compare the permitted methods
| Method | Basis |
|---|---|
| Gross receipts | 4% of qualified export receipts plus 10% of eligible export promotion expenses |
| Combined taxable income | 50% of CTI plus 10% of eligible export promotion expenses |
| Section 482 | Arm's-length pricing on the actual price; Schedule P not completed |
The 10% applies to export promotion expenses, not to receipts. Verify the formulas against section 994 and the Treasury regulations for your year.
Neither administrative method may create a loss for the related supplier. A special cost-recovery rule applies where there is no CTI.
Apply the gross-receipts method carefully
The base is qualified export receipts only, after removing excluded amounts and adjustments. The result is then tested against CTI on Part I, Section C, lines 21 to 23.
Example: qualified export receipts of US$1,000,000 and export promotion expenses of US$20,000 produce 4% of 1,000,000 plus 10% of 20,000 = US$42,000, before the CTI comparison.
Confirm the current-year formula and limits first.
Calculate combined taxable income
Determine income from the qualifying export transactions after allowable cost allocations. The 50% method takes the smaller of CTI and the computed amount on line 17. Document every assumption and allocation.
For commissions, Part III line 30 adds line 27 taxable income, line 28 export promotion expenses and line 29 other allocable IC-DISC expenses. Allocated profit is not the final commission.
Arm's-length pricing and marginal costing
A section 482 analysis can require comparables, a functional analysis and detailed intercompany documentation. Marginal costing is narrower. It applies only to sales of property (or commissions on them) under the 50-50 method, not to leases or services.
Grouping rules:
- Default is transaction-by-transaction
- Annual product or product-line grouping is allowed
- Every transaction in the elected product or line must be grouped
- Each group is limited to one transaction type
Select and document the method
When choosing a method, weigh:
- Transaction volume and margins
- Product lines and cost-record quality
- Documentation strength and administrative effort
- Audit defensibility
Do not assume an outcome. Workpapers should state why the method was chosen, what alternatives were evaluated, which transactions were grouped and how the result complies with current rules.
Complete, Reconcile and Review Schedule P
Map the calculation to the current form
Use the current form and instructions. The December 2025 instructions specify the September 2017 Schedule P, but check for revisions each year. Map workpaper totals to the applicable parts and lines, and attach any required statements.
Report the correct transaction type
Distinguish a transfer-price arrangement (Part II) from a commission arrangement (Part III), and make sure the form matches the actual agreement. Check that names, identification numbers, accounting periods, currencies, receipts, costs and calculated amounts are consistent throughout.
Reconcile with the full return
Reconcile Schedule P to:
- The IC-DISC's books and the main return
- Shareholder reporting on Schedule K, and Form 8404 where deferred DISC income applies
- The related supplier's commission or transfer-price entries
Investigate timing differences, currency conversion, returns, accruals and classification changes before filing. The IRS's archival IC-DISC audit guide shows that unclear supplier-to-Schedule-P trails make duplicated transactions hard to detect.
Filing-readiness review
- Deadline: the 15th day of the 9th month after year-end, with next-business-day relief for weekends and holidays.
- Extensions: none are allowed for this return. Form 7004 does not extend it.
- Signature: a dated signature from an authorised corporate officer.
- Mailing: confirm the current address on the IRS where-to-file page.
Confirm all attachments, agreements and explanations are complete, and review current-year form changes.
Avoid common errors
- Including non-qualified receipts
- Using unsupported cost allocations
- Mixing transfer-price and commission calculations
- Grouping leases with sales
- Misreading the 10% as a percentage of receipts
- Copying prior-year figures
- Not reconciling both sides of the intercompany entry
Arrange a second-person review by a tax professional familiar with IC-DISC rules, especially with multiple products, currencies, related entities or Australian and U.S. considerations.
Conclusion and Next Steps
Accurate Schedule P preparation rests on three linked controls:
