California Form CDTFA-1116 is the Certificate of Exemption – Sales to the United States and Its Instrumentalities, and it is the document a California seller uses to support a sales tax exemption when selling tangible personal property directly to the federal government. The certificate is issued by the California Department of Tax and Fee Administration (CDTFA) under Revenue and Taxation Code §6381 and Regulation 1614.
If you take the certificate in good faith, keep it in your records, and the sale truly qualifies, the seller is relieved of liability for the sales tax. If you skip the form or accept it from the wrong party, CDTFA can assess the full California base rate of 7.25% plus district taxes that push the rate as high as 10.75%, with interest under §6591 and negligence penalties under §6484.
According to CDTFA audit data summarized in Publication 102, missing or defective exemption certificates are one of the top three audit adjustments for California retailers, and roughly one in four contested federal-sale exemptions fail at audit because of paperwork problems rather than the underlying transaction.

What CDTFA-1116 Is and Who Must File It
CDTFA-1116 is a seller-retained exemption certificate. The seller does not mail it to CDTFA. Instead, the seller fills in the top portion identifying the transaction, and an authorized federal officer signs the bottom certifying that the buyer is the United States or one of its instrumentalities. The seller then keeps the certificate for at least four years under Regulation 1698, and longer if an audit is open.
The form rests on R&TC §6381, which exempts sales made directly to the United States, its unincorporated agencies and instrumentalities, the American Red Cross, federal reserve banks, federal credit unions, federal land banks, and federally chartered production credit associations. Regulation 1614 and Publication 102 flesh out the rules, including how the GSA SmartPay program is treated.
The filer profile is broad. Office-supply stores selling to a Navy base, construction suppliers selling rebar to a federal contractor, IT vendors selling laptops to a VA hospital, and even small specialty shops selling to a USPS facility all may need this form. The buyer side is usually a contracting officer, a card-program coordinator, or an authorized purchaser. Both sides have a stake: the seller protects its books from audit, and the buyer protects the agency from being charged tax it does not owe.
A common misconception is that any sale that mentions a federal agency qualifies. That is wrong. Sales to federal employees personally, to prime contractors buying for their own consumption, and to incorporated federal entities like the TVA in some contexts are taxable. Form CDTFA-1116 must reflect a real direct sale to the United States, or it gives the seller no protection at all.
Before You Start: Documents and Information You Need
Get your paperwork in one place before you open the form. Filling out CDTFA-1116 takes minutes when the documents are ready and hours when they are not. The certificate is short, but every line ties back to a record the seller must keep alongside it.
Use this pre-filing checklist. Each item has a reason and a consequence if it is missing.
- Seller’s permit number issued by CDTFA — proves you are a registered California retailer; missing this can void the certificate at audit.
- Federal purchase order or contract number — ties the sale to a federal obligation; without it, CDTFA may treat the sale as a private purchase.
- GSA SmartPay card receipt or imprint — shows whether the card is centrally billed (exempt) or individually billed (taxable); the wrong card type flips the answer.
- Contracting officer’s printed name, title, and agency — the only people who can sign for the United States are authorized agents; unauthorized signatures are fatal.
- Itemized invoice or sales slip — describes the property sold; vague descriptions create audit findings.
- Delivery address on a federal installation or to a federal agent — confirms the buyer took title as the United States; drop-shipping to a contractor’s yard breaks the chain.
- DUNS or UEI number of the federal entity — useful cross-reference for audit; missing identifiers slow down audit defense.
- Date of sale and invoice number — anchors the certificate to a specific transaction; a generic certificate covering “all future sales” is invalid for one-time sales.
- Copy of the federal agent’s ID or credentials — proves authority; auditors often ask for this when sales are large.
- Seller’s internal exemption log — tracks which invoices a certificate covers; a missing log is the single biggest audit weakness.
Where to Get the Form and How to Access It
The official current version of the form lives on the CDTFA website. Download the latest PDF from the CDTFA Forms and Publications page or directly from the CDTFA-1116 PDF. Always check the REV. date printed in the lower-left corner so you know you have the current version; older revisions still float around in vendor folders and can confuse auditors.
You can also request the form by phone from the CDTFA Customer Service Center at 1-800-400-7115, by visiting any CDTFA field office, or by asking your federal buyer for their preferred copy. Many federal contracting offices keep CDTFA-1116 templates pre-filled with their agency block to speed up vendor onboarding.
The form is fillable in Adobe Acrobat. You may type the entries, print them, or complete the form by hand in blue or black ink. CDTFA accepts either, but typed entries reduce errors and speed up audit review. If you complete it electronically, save a flattened PDF copy so the data cannot be edited later.
A misconception is that the form must be notarized or filed with CDTFA. It does not. The signature of the authorized federal officer is what gives it force, and the seller simply files it with the matching invoice. Treating it as a “send-in” form wastes time and can confuse buyers who expect to keep their own copy as well.
Step-by-Step: How to Fill Out CDTFA-1116 Line by Line
The form is one page. Despite its short length, every field carries weight. Use the order below, which mirrors the layout of the current CDTFA-1116 revision. Italicized text shows what an actual entry looks like on the page.
Field 1: Seller’s Name
This field asks for the legal name of the California retailer making the sale. Write the exact name printed on your CDTFA seller’s permit, not a “doing business as” name unless that DBA is also on the permit. For example, Bayside Office Supplies, Inc. writes its full corporate name, not Bayside.
If you operate under a DBA, write the legal name first, then “dba” and the trade name, like Bayside Office Supplies, Inc. dba Bayside Office. A common mistake is using only the storefront name, which can break the link to your seller’s permit at audit and cause the certificate to be disregarded. The consequence is a tax assessment on the entire sale plus interest. A misconception is that “any name the buyer recognizes” is enough; CDTFA checks against permit records, not informal names.
Field 2: Seller’s Address
This is the seller’s principal place of business, the address tied to your seller’s permit. Use the street address, city, state, and ZIP. For example, 1450 Harbor Blvd., Oakland, CA 94607. Do not use a remote shipping warehouse or the buyer’s address.
If you have multiple locations under one permit, list the headquarters address and note the selling location elsewhere on the invoice. A common mistake is entering a P.O. Box only; CDTFA wants a physical address, and a P.O. Box-only entry can be rejected at audit. The consequence is the loss of the exemption for that sale. A misconception is that the address must match the invoice’s “ship from” location; it must match the permit, not the warehouse.
Field 3: Seller’s Permit Number
Enter the eight- or nine-digit California seller’s permit number, formatted as printed on the permit, such as SR FH 12-345678. If your account is a Certificate of Registration – Use Tax account, write that number and check any box the form provides for non-permit sellers.
The most common mistake here is transposing digits or using an old, closed permit number from a prior business. The consequence is that CDTFA cannot tie the certificate to an active account, and the exemption can be denied. A misconception is that a federal EIN can substitute; it cannot. The CDTFA permit number is the only acceptable identifier, and you can verify yours through the CDTFA permit verification tool.
Field 4: Purchaser’s Name (United States or Instrumentality)
Write the exact federal entity that is the buyer of record. Do not write the contracting officer’s personal name here. For example, Department of the Navy, Naval Base San Diego or United States Postal Service, Oakland Processing Facility.
The nuance is naming an “instrumentality” precisely. The American Red Cross writes The American National Red Cross. A federal credit union writes its full chartered name, like Navy Federal Credit Union. A common mistake is naming a prime contractor — for example, writing Lockheed Martin when the actual buyer for tax purposes is the United States. The consequence is the certificate is invalid, because Lockheed is not the United States. A misconception is that any agency tied to the federal government qualifies; the entity must fall within R&TC §6381 or be recognized as a federal instrumentality under Regulation 1614.
Field 5: Purchaser’s Address
Use the address of the federal facility, office, or installation receiving the goods. For example, Naval Base San Diego, 3455 Senn Rd., San Diego, CA 92136. If goods are delivered to a different federal address, list the receiving address and add the contracting office’s address as a secondary line.
The nuance is that the address must reflect a federal location or a federal agent’s office, not a contractor’s job site. A common mistake is using the construction site of a private prime contractor; that breaks the direct-sale chain under Regulation 1521. The consequence is reclassification of the sale as a taxable sale to the contractor. A misconception is that any “federal project” address qualifies; only a federal address tied to the federal buyer of record works.
Field 6: Description of Property Purchased
Describe the tangible personal property being sold with enough detail that an auditor can match it to the invoice. Write 50 cases HP LaserJet toner, model CF258A rather than office supplies. List quantities, model numbers, and a short product label.
The nuance covers mixed orders. If the order has both exempt items and items the federal buyer is not actually purchasing for itself, list only the exempt items. A common mistake is using catch-all phrases like miscellaneous, which auditors flag as unreliable. The consequence is the auditor backs out the exemption for any item not clearly identified. A misconception is that the invoice description alone is enough; CDTFA wants a description on the certificate that matches the invoice, not just the invoice.
Field 7: Purchase Order or Contract Number
Enter the federal purchase order, contract number, or task order, formatted exactly as the agency issued it. For example, N00244-26-P-1234 for a Navy purchase order or GS-07F-1234X for a GSA schedule task order.
The nuance is that the same sale can have a contract number, a delivery order number, and a task order number. List the most specific one and reference the others on the invoice. A common mistake is leaving this blank when the buyer pays by GSA SmartPay card; you should still record the agency requisition or order number even when a card is used. The consequence of leaving it blank is that the auditor cannot verify a federal obligation existed. A misconception is that a credit card receipt replaces a PO number; it does not.
Field 8: Method of Payment
Indicate how the United States paid. Common entries include Federal purchase order, paid by U.S. Treasury check, GSA SmartPay 3 Centrally Billed Account (CBA), or Electronic funds transfer from U.S. Treasury. The method tells the auditor whether the United States was directly obligated.
The nuance is the GSA SmartPay test. Under Publication 102 and the GSA SmartPay program, only centrally billed accounts (CBAs) are sales to the United States. Individually billed accounts (IBAs), where the cardholder is personally liable, are taxable sales to the employee. A common mistake is treating every government-issued card as exempt. The consequence is a full tax assessment on every IBA sale plus penalties. A misconception is that the card design or color tells you the answer; only the first six digits (BIN) and the SmartPay tax-advantage status confirm CBA versus IBA.
Field 9: Date of Sale
Enter the date the title to the goods passed, formatted MM/DD/YYYY, for example 03/14/2026. This date controls which tax rate would have applied and whether the certificate was timely.
The nuance is that the certificate should be dated on or near the date of sale. Certificates collected long after the fact are still valid if taken in good faith, but auditors view late-dated certificates with suspicion. A common mistake is dating the certificate the day of the audit. The consequence is the auditor may treat it as not taken in good faith under Regulation 1667. A misconception is that no date is needed because the form is “general”; CDTFA-1116 is transactional, not blanket.
Field 10: Authorized Federal Officer’s Signature
Only an authorized federal officer can sign for the United States. This is usually a contracting officer, a card-program coordinator for SmartPay CBA purchases, or another federal agent with delegated procurement authority. The officer signs in ink (or with a verifiable e-signature) and certifies the buyer is the United States or an instrumentality.
The nuance is the difference between a contracting officer and a “buyer.” A GS-07 administrative buyer with no warrant cannot sign. A common mistake is letting a federal employee who is just picking up the goods sign. The consequence is the certificate is void and the seller owes the tax. A misconception is that a typed name is a signature; CDTFA expects an actual signature, with the printed name in the next field.
Field 11: Printed Name and Title of Federal Officer
Print the officer’s full name and exact title, such as Lt. Cmdr. Janet Reyes, Contracting Officer, Naval Base San Diego. The title shows the warrant or authority.
The nuance is that titles like Purchasing Agent or Card Program Coordinator are acceptable when tied to actual procurement authority. A common mistake is listing a generic Buyer with no agency or warrant context. The consequence is the auditor cannot confirm authority and may disallow the exemption. A misconception is that rank alone proves authority; civilian agencies use warrants, not rank.
Field 12: Date Signed
Enter the date the federal officer actually signed the certificate, in MM/DD/YYYY format. This date may differ from the date of sale, but should not predate it.
The nuance is that an officer can sign before delivery (when the PO is cut) or after (when goods are accepted). A common mistake is leaving this blank, which makes the certificate unenforceable. The consequence is the seller loses the good-faith defense. A misconception is that the signature date and date of sale must be identical; they need only be reasonably close and consistent with the procurement timeline.

How to File the Completed Form
CDTFA-1116 is not filed with CDTFA. The seller retains it. Still, “filing” in the practical sense means producing it on demand and storing it correctly. Treat the certificate like a tax-record original, because that is what it becomes the moment an auditor opens your file.
Retention. Keep the original (or a high-quality scan) for at least four years from the date of sale, per Regulation 1698. If a CDTFA audit, federal contract dispute, or BOE appeal is pending, keep it until the matter closes plus four more years.
Storage channels. Sellers may keep paper originals, scanned PDFs in a document-management system, or both. CDTFA accepts electronic copies if they are legible, complete, and reproducible, under Regulation 1698. Many retailers index the certificate to the matching invoice number for quick retrieval.
Audit production. When CDTFA audits you through the CDTFA online portal, the auditor lists exempt sales and asks for the supporting certificate. Produce CDTFA-1116, the matching invoice, the federal PO, and the SmartPay receipt or Treasury proof. Sellers who keep all four together typically clear the line item without adjustment. Processing time for an exempt-sale review during audit is usually 30 to 90 days from production.
Proof of receipt. When you give a copy back to the federal buyer (most do not require it, but some agencies do), send it by encrypted email or a tracked courier and keep the delivery confirmation. There is no fee, no payment method, and no agency portal for filing CDTFA-1116 itself.
What Happens After You File
After the certificate is signed and stored, three things happen across the life of the sale. First, your accounting system tags the invoice as exempt and the sales tax field reads zero on that line. Your monthly or quarterly sales and use tax return reports the gross sale and then deducts it on the “Sales to the United States Government” line, schedule code typically 200304 depending on filing system.
Second, the federal buyer records the purchase in its agency books and, if a SmartPay CBA was used, GSA reconciles the central bill at the agency level. Sellers do not need to track this, but they may receive periodic confirmations from large agency procurement offices.
Third, CDTFA may select your account for audit. If selected, the auditor pulls a sample of exempt sales and traces each back to a certificate. A clean CDTFA-1116, properly signed and matched to a PO and invoice, ends the inquiry on that line. A defective certificate moves the line into a “proposed adjustment” schedule, and tax, interest, and possibly penalties follow under §6484 and §6591.
A misconception is that “the IRS” or another federal agency reviews CDTFA-1116. It does not. This is a California state document, governed entirely by CDTFA, even though the buyer is federal. The federal side cares only that the agent had authority and the agency was the buyer of record.
Mistakes to Avoid When Filling Out the Form
These are the errors CDTFA auditors flag most often. Each one has cost real California sellers real money. Fix them at the desk, not in the audit room.
- Accepting an IBA SmartPay card. Individually billed cards are taxable; the consequence is full tax due on the sale.
- Letting a non-warranted employee sign. Only contracting officers or delegated agents may sign; otherwise the certificate is void.
- Naming the prime contractor as the purchaser. That breaks the direct-sale chain and converts the sale to a taxable contractor sale.
- Leaving the PO or contract number blank. Without it, the auditor cannot verify a federal obligation existed.
- Using vague property descriptions. “Office supplies” is rejected; auditors back out the exemption.
- Dating the certificate after the audit notice. Late certificates can fail the good-faith test under Regulation 1667.
- Mismatching seller name to the permit. A storefront name that is not on the permit can be disregarded.
- Using a P.O. Box only for the seller address. CDTFA expects a physical address; the certificate may be rejected.
- Failing to retain for four years. A purged certificate cannot be produced, so the exemption fails by default.
- Mixing exempt and taxable items on one line. This blurs which goods qualify; the auditor disallows the entire line.
- Treating a federal employee’s personal purchase as exempt. Personal sales to federal employees are taxable.
- Skipping the certificate because the invoice “looks federal.” No certificate, no exemption, regardless of how the invoice looks.
Do’s and Don’ts
Use this short list as a desk reference. Every point ties to a real audit-tested rule.
- Do verify the seller’s permit number against your CDTFA account before signing, because a stale permit number voids the certificate.
- Do confirm SmartPay CBA versus IBA at the point of sale, because the card type controls the exemption.
- Do match the certificate to a specific invoice number, because blanket “future sales” certificates fail audit.
- Do keep the federal PO, the certificate, and the invoice stapled or linked, because auditors expect a clean trail.
- Do train cashiers on the difference between federal employees and federal agencies, because the wrong call is expensive.
-
Do scan the signed certificate the same day, because lost paper is the most common cause of failed exemptions.
-
Don’t accept a typed-only signature without a printed name and title, because CDTFA may reject it.
- Don’t rely on the buyer’s verbal claim of authority, because only a warrant or written delegation counts.
- Don’t treat a sale to a federal contractor’s job site as a federal sale, because title usually rests with the contractor.
- Don’t discard the certificate before four years pass, because the retention period is statutory.
- Don’t combine exempt and non-exempt items on the same certificate line, because the auditor will disallow the whole line.
- Don’t assume an old REV. version of the form is fine, because outdated revisions can confuse auditors and slow the review.
Pros and Cons of Filing on Your Own vs. With Help
Most retailers complete CDTFA-1116 in-house. Larger sellers and contractors with high audit risk often use a CPA or sales-tax specialist. The right choice depends on volume, risk, and your team’s training.
Pros of doing it in-house: – No outside fee, since the form takes minutes to complete. – Faster turnaround at the register or order desk. – Direct relationship with your federal buyer, which speeds re-orders. – Builds internal tax knowledge that helps with other CDTFA forms. – Easier to attach to your own invoice and document-management system.
Cons of doing it in-house: – Higher risk of overlooking the IBA versus CBA SmartPay distinction. – Staff turnover means training has to repeat. – One bad certificate can cost more than a year of professional fees. – Audit defense falls on people who do not do audits for a living. – No second set of eyes on contractor-versus-government sales.
Pros of using a CPA or sales-tax specialist: – Expert review of edge cases like federal instrumentalities and Red Cross sales. – Reliable audit defense, including representation before CDTFA. – Standardized templates and retention policies across multiple sellers. – Faster identification of risky transactions before they post. – Strong position on negligence-penalty waivers if errors do occur.
Cons of using a CPA or sales-tax specialist: – Fees can run hundreds of dollars per matter or hourly. – Slower turnaround during peak procurement seasons. – Buyer interactions go through a third party, which annoys some federal officers. – Smaller sellers may not see enough exempt volume to justify the cost. – Specialist advice still needs implementation by store staff.

Key Entities That Interact With CDTFA-1116
Several agencies and authorities sit alongside this certificate. Each one plays a defined role.
The CDTFA administers the sales and use tax and audits California retailers. The General Services Administration runs the GSA SmartPay program and publishes the BIN list that drives CBA-versus-IBA classification. The Office of the State Controller handles state-side appeals through the Office of Tax Appeals when an audit is contested. The federal contracting agency — Navy, USPS, USACE, VA, GSA, and others — supplies the buyer of record and the warranted officer who signs. The American Red Cross, federal credit unions, and federal reserve banks are statutory federal instrumentalities listed in §6381.
Court and agency decisions also shape this form. The U.S. Supreme Court’s holding in United States v. New Mexico, 455 U.S. 720 (1982), confirms that states cannot tax direct sales to the United States, while McCulloch v. Maryland sets the older constitutional baseline. CDTFA’s Annotation 495.0560 and similar Business Taxes annotations spell out how California applies these rules in practice.
FAQs
Is CDTFA-1116 the same as a resale certificate?
No. A resale certificate (CDTFA-230) supports purchases for resale, while CDTFA-1116 supports a direct sale to the federal government. The forms cover different exemptions and are not interchangeable.
Can a federal employee sign CDTFA-1116 with their personal credit card?
No. Personal cards make the employee the buyer, not the United States. Such sales are taxable, and the certificate is invalid for that transaction.
Does a GSA SmartPay travel card automatically qualify?
No. Most travel cards are individually billed accounts. Only centrally billed accounts under SmartPay are direct sales to the United States and qualify for exemption.
Do I need to mail CDTFA-1116 to the CDTFA?
No. The seller keeps the certificate in its records for at least four years. CDTFA reviews it only during audit or document requests.
Is a sale to a federal contractor’s job site exempt?
No. Sales where title passes to the contractor are taxable, even on federal projects. Only direct sales to the United States qualify under §6381.
Should I write the contracting officer’s name in the Purchaser’s Name field (Field 4)?
No. Field 4 takes the federal entity’s name, like U.S. Department of the Navy. The officer’s name belongs in the signature and printed-name fields.
Can I use a single CDTFA-1116 for many future sales to the same agency?
No. Each sale needs its own certificate tied to a specific PO, date, and invoice. Blanket certificates fail at audit.
Does the Red Cross qualify for CDTFA-1116 exemption?
Yes. The American National Red Cross is a federal instrumentality under §6381, so direct sales to it can be supported by CDTFA-1116.
Should I leave Field 7 blank if the buyer used a SmartPay CBA card?
No. Even with a card, record the agency requisition or order number in Field 7 to prove a federal obligation existed.
Is an electronic signature on CDTFA-1116 acceptable?
Yes. CDTFA accepts verifiable e-signatures on flattened PDFs, provided the printed name, title, and date are also entered.
Do I need to enter both the date of sale (Field 9) and date signed (Field 12)?
Yes. Both fields are required, and the dates should be consistent with the procurement timeline to support a good-faith claim.
Can a sale to a national bank or federal credit union use CDTFA-1116?
Yes. Federal credit unions and federal reserve banks are listed instrumentalities, so direct sales to them qualify under §6381.
Is the seller liable if the federal officer lacked authority?
Yes. If the signer was not warranted, the certificate is void and the seller owes the tax, unless the seller can prove good-faith reliance.
Do I need to keep the SmartPay receipt with the certificate?
Yes. The receipt or BIN documentation proves CBA status and is the single most useful supporting document at audit.
