Financial Accounts

Why Have a User Financial Account?

Each user group should establish a user financial account to send samples, dewars, or other equipment between SLAC and their institution if the group will be using SLAC for shipping.

Establishing/Renewing a User Financial Account

The most common method of establishing or renewing a user financial account is by providing a purchase order (PO) (or a letter from the financial officer of the user institution). The PO should be made to SLAC National Accelerator Laboratory for the amount of estimated expenditures (the suggested minimum is $2,000). The PO should include the institution contact, user names, expiration date, funding agency, grant/contract number and whether expenditures are taxable in California. Terms and Conditions should not be included (if Terms and Conditions are preprinted on the form, they should be disclaimed). Send the completed User Financial Account Form and purchase order to:

Additional Charges

  • Sales Tax: California sales and use tax of 9.0% will apply to the price of all materials purchased and delivered in the state of California.

    ** If not taxable and not DOE M&O, provide documentation indicating this status. Tax exemptions awarded under IRS rulings are not accepted by the California Board of Equalization; Sales tax exemptions awarded under individual state rulings apply only to the state making the ruling. The State of California does not recognize or extend reciprocity of tax-exempt status to other states. The only provision which will establish tax-exempt status under California ruling is that the title of property purchased for use in California vests with the United States government.

  • SLAC Overhead: Additional charges apply for materials, supplies and services procured by users through a SLAC user financial account. Materials, supplies ~9.765% (if using SLAC's e-procurement the rate is ~4.725%), SLAC Labor ~56%.

  • Other Miscellaneous Charges: Safeguard & Security Charge ~1.5% charged to all non-DOE projects/facilities, Federal Administrative Charge ~3% charged to all foreign and domestic entities (excluding domestic non-profits or educational institutions)


Invoices will be submitted to the user institution for costs incurred by the user group to support their experiments at SLAC’s user facilities. Payments should reference the invoice and user account (project-activity) numbers. Send to:
