The federal ordering activity pays the Industrial Funding Fee — it is baked into your awarded GSA Schedule price — but you are the one who remits it to GSA. The rate is 0.75% of reported sales. As of 2026, Transactional Data Reporting is mandatory across all MAS Special Item Numbers, which moved reporting to monthly while leaving remittance quarterly.
That split is where contractors get into trouble. I have watched more than one Schedule holder discover, three years into an award, that they priced their labor categories at exactly their commercial rate and have been paying the IFF out of profit ever since. The fee is small. The compounding error is not.
What is the GSA Industrial Funding Fee (IFF)?
The IFF is a 0.75% fee charged on orders placed against your GSA Multiple Award Schedule contract. It reimburses GSA's Federal Acquisition Service for the cost of operating the Schedules program under 40 U.S.C. 321, the Acquisition Services Fund. The governing clause is GSAR 552.238-80, Industrial Funding Fee and Sales Reporting.
The mechanics are set out in GSAR 552.238-80. Three points define the whole obligation:
- Offerors must include the IFF in their prices. The fee is inside the awarded price and reflected in the total amount charged to the ordering activity.
- The reported sales value includes the IFF. You report the full price the Schedule user paid — not your net after the fee.
- FAS can change the rate. GSA holds a unilateral right to adjust the percentage, no more than once per year, with reasonable notice. Current rates are posted at the Vendor Support Center and the FAS Sales Reporting Portal.
Who actually pays the IFF — the government or the contractor?
Legally, the ordering activity pays it. The Alternate I text is explicit: the IFF "is paid by the authorized ordering activity but remitted to GSA by the Contractor." In practice, whoever absorbed the 0.75% at pricing time is the one who pays. If you did not gross up your rates, you did.
When I sat on the other side of the desk as a GSA Contracting Officer, this was one of the quiet tells that separated a prepared offeror from an unprepared one. An offeror who submitted a rate sheet identical to their commercial price list had not thought the fee through. An offeror whose Schedule rates sat a fraction above their commercial rates, with the delta explained in the narrative, had.
The arithmetic is not intuitive, because the IFF is a percentage of the price paid — not a markup on your net.
| What you want to net | What you must price at | IFF remitted |
|---|---|---|
| $100,000 | $100,755.67 | $755.67 |
| $250,000 | $251,889.17 | $1,889.17 |
| $1,000,000 | $1,007,556.67 | $7,556.67 |
Divide by 0.9925. Do not multiply your net by 0.75%. Contractors who multiply under-collect every single order, and the shortfall is invisible until an audit or a margin review surfaces it.
How is the IFF calculated and remitted?
Multiply total reported sales for the period by 0.0075. Remit to FAS in U.S. dollars within 30 calendar days after the end of the reporting quarter. Final payment is due within 30 days after physical completion of the last outstanding task or delivery order.
- Close your books for the period using a consistent accounting method tied to your established commercial practice.
- Report sales in the FAS Sales Reporting Portal, broken out by SIN, NSN, or sub-item.
- Report zero sales when you have none — silence is a violation, not a pass.
- Remit 0.75% of reported sales within 30 calendar days of quarter end.
- Convert foreign-currency sales using the Treasury Reporting Rates of Exchange in effect on the last day of the quarter.
What changed in 2026 now that TDR is mandatory?
MAS Solicitation Refresh 31 expanded Transactional Data Reporting to all remaining service SINs and made TDR mandatory across the MAS program. Contractors who accepted the associated Mass Modification by June 30, 2026 had a TDR participation date of July 1, 2026. Reporting is now monthly. Remittance is still quarterly.
The switch replaces the basic clause with Alternate I of GSAR 552.238-80, and the two are not cosmetically different. Here is what actually moves:
| Requirement | Basic clause (legacy) | Alternate I (TDR) |
|---|---|---|
| Reporting frequency | Quarterly | Monthly |
| Reporting deadline | 30 days after quarter end | 30 days after last calendar day of the month |
| What you report | Dollar value by SIN/NSN | 11 transactional data elements per line |
| Acceptable reporting points | Receipt of order, shipment/delivery, invoice, or payment | Invoice issuance or receipt of payment only |
| No-activity period | Report zero sales | Submit confirmation of no reportable data |
| IFF remittance | Quarterly, within 30 days | Quarterly, within 30 days |
The Short Version
Look hard at row four. Under the basic clause you could recognize a Schedule sale at receipt of order. Under TDR you cannot — your only options are invoice issuance or receipt of payment. If your accounting system has recognized sales at order receipt for the last decade, your reporting point changed the day your TDR participation began, and the transition period will either double-count or drop a set of orders depending on which direction you shift. Reconcile that boundary quarter deliberately. Nobody at FAS is going to flag it for you.
The 11 required data elements under Alternate I include contract or BPA number, delivery/task order number (PIID), non-federal entity, description of deliverable, manufacturer name and part number, unit of measure, quantity sold, universal product code, price paid per unit, and total price. Price paid per unit and total price must include the IFF.
Which sales are reportable for IFF — and which are not?
Reportable sales are sales of contract items to authorized users under your Schedule. Sales made under a separate contracting authority are not reportable and carry no IFF. Cooperative Purchasing sales to state and local governments are reportable and do carry the fee.
- Reportable: orders placed against your MAS contract by federal agencies and other authorized users.
- Reportable: Cooperative Purchasing sales to state and local government entities. This one gets missed constantly.
- Not reportable: work performed under a Governmentwide Acquisition Contract such as SEWP VI or Alliant.
- Not reportable: separately awarded FAR Part 12, 13, 14, or 15 procurements.
- Not reportable: non-FAR contracts and purely commercial sales.
As a Contracting Specialist at GSA, the sales-reporting discrepancies I saw most often were not fraud. They were a contractor sweeping every federal dollar into the Schedule report because it felt safer — and over-remitting the IFF on GWAC revenue that never belonged there. Over-reporting is not a compliance cushion. It is money you gave away, and it distorts the sales history GSA uses at option renewal.
Who pays the IFF when you source from another contractor's Schedule?
The IFF is owed once, by the contractor whose Schedule the order was placed against. If you buy from another Schedule holder and resell to the government on your own contract, that purchase is a commercial transaction to them and a reportable Schedule sale to you. You remit. They do not.
Run it the other way and the answer flips. If the agency placed the order against the other contractor's Schedule and you are performing as their subcontractor, they hold the reporting and remittance obligation. Your invoice to them is commercial revenue.
The failure mode I want you to avoid: both parties assume the other is remitting, and neither does. That is not a rounding error — under GSAR 552.238-80(d) an unpaid IFF becomes a contract debt to the United States.
What happens if you remit the IFF late?
Failure to remit the full IFF within 30 calendar days after the reporting period ends constitutes a contract debt under FAR Subpart 32.6. GSA can withhold or offset payments and charge interest under FAR 52.232-17. Failure to report, falsified reports, or late payment are each sufficient cause to terminate the contract for cause.
Termination for cause over a missed 0.75% payment sounds disproportionate until you have read the clause. It is right there in the text, and it is the reason I tell clients to calendar the four remittance dates the week the contract is awarded rather than trusting a reminder email. In eighteen years across federal acquisition — as a Contracting Specialist and later a Contracting Officer at GSA, IRS, DoD, DOI, HHS, FTC, and Energy — the contract actions that escalated fastest were almost never the complicated ones. They were the administrative obligations somebody assumed were optional.
What Should You Do Now?
- Check whether your awarded price actually contains the IFF. Divide your target net by 0.9925. If your Schedule rate equals your commercial rate, you are absorbing the fee.
- Confirm your TDR participation date and whether your reporting point changed from order receipt to invoice or payment. Reconcile the transition quarter line by line.
- Separate GWAC and open-market revenue out of your Schedule reports. Over-remitting is not conservatism.
- Report zero-sales months. Under TDR that means an affirmative confirmation of no reportable data, not silence.
- Calendar all four remittance deadlines — 30 days after each calendar quarter — and treat them like a tax filing.
- Verify who remits on every teaming or reseller arrangement before the first invoice goes out, in writing.
If you are heading into a Schedule award, an option renewal, or a TDR transition and you are not certain your pricing carries the IFF correctly, this is exactly the kind of thing worth having reviewed by someone who evaluated these files from the government side. You can see how we handle ongoing GSA Schedule maintenance and compliance, including sales reporting and IFF remittance.
Frequently Asked Questions
What is the current GSA Industrial Funding Fee rate?
The IFF rate for the GSA Multiple Award Schedule program is 0.75% of reported sales. GSA's Federal Acquisition Service holds the unilateral right to change the percentage no more than once per year with reasonable notice. The current rate is posted at the Vendor Support Center and the FAS Sales Reporting Portal.
Is the IFF paid by the government or the contractor?
The authorized ordering activity pays the IFF, because the fee is required to be included in your awarded Schedule price. The contractor collects it as part of the order price and remits it to GSA. If you did not build the 0.75% into your pricing, you are effectively paying it out of your own margin.
Do I have to report zero sales on my GSA Schedule?
Yes. Under the basic clause you must file a quarterly report showing zero sales. Under Transactional Data Reporting you must submit a confirmation of no reportable transactional data within 30 calendar days of the last day of the month. Not filing is a reporting violation.
Does the IFF apply to Cooperative Purchasing sales to state and local government?
Yes. GSAR 552.238-80 states that sales made to state and local governments under Cooperative Purchasing authority count as reportable sales for IFF purposes. This is one of the most commonly missed categories in sales reporting.
Under TDR, do I still remit the IFF quarterly?
Yes. Transactional Data Reporting moved sales reporting to a monthly cadence, but IFF remittance remains quarterly — due within 30 calendar days after the last calendar day of the reporting quarter. Reporting frequency and remittance frequency are two separate obligations.
Do I owe the IFF on sales made through a GWAC like SEWP VI?
No. Sales conducted under a separate contracting authority — a Governmentwide Acquisition Contract, or a separately awarded FAR Part 12, 13, 14, or 15 procurement — are not reportable Schedule sales and carry no IFF. Reporting them anyway means over-remitting money you do not owe.
What happens if I pay the GSA IFF late?
An unpaid IFF becomes a contract debt to the United States under FAR Subpart 32.6. GSA may withhold or offset payments and assess interest under FAR 52.232-17. Failure to report sales, falsifying reports, or failing to timely pay the IFF are each sufficient cause for termination for cause.
