Recordkeeping for Ground, Air, and Rail

As a transportation provider, you must keep records of all the purchases and sales that your business makes. Your records must show that you properly collected, reported and paid or forwarded taxes to Idaho.

Records to keep

  • Normal books of account
  • Documents that support entries in the books of account

    Examples:

    • Sales records
    • Bills
    • Receipts
    • Invoices
    • Credits granted
    • Job, work orders, or bills of lading
    • Contracts
    • All schedules or working papers used to prepare your tax returns
  • Tax returns; see Filing a return and forwarding tax to the state
  • Copies of sales tax resale or exemption certificates (Form ST-101)

Note: Keep a buyer’s exemption certificate for as long as you do business with that buyer, plus four years. We’ll bill you for tax due if you don’t have completed exemption certificates for buyers you sell exempt to.

What records must show

  • Gross receipts showing sales and services were made or received in Idaho, even those sales that you or your customer think are exempt from tax. If you deliver the product or service somewhere other than your place of business, you must also keep records that prove where delivery took place.
  • Copies of properly completed exemption forms showing the identity of customers claiming an exemption, the type of exemption, and what you sold them exempt.
  • All deductions claimed in filing returns.
  • The total purchase price of anything bought for sale, rental, lease, or your own use.
  • The amount of sales tax collected from your customer or that you paid to a vendor.

You must keep all sales and use tax records for at least four years. You should keep records for seven years if you don’t file returns.
