North Dakota Bookkeeping

Keeping records that support the books

A taxpayer must maintain all records that are necessary to a determination of the correct tax liability under Title 57 of the North Dakota Century Code. All required records must be made available on request by the Tax Commissioner or an authorised representative. The regulation, North Dakota Administrative Code 81 01.1 04 03, lists the kinds of material covered in broad terms, including accounting schedules, books, contracts, ledgers, journals, books of account, summaries of accounts, correspondence, and electronically stored information.

If a taxpayer keeps required records in both electronic and hard copy formats, the taxpayer must make the records available to the Tax Commissioner in electronic format on request. Keeping hard copy records as well does not remove that duty. Source: https://www.law.cornell.edu/regulations/north-dakota/N-D-A-C-81-1.1-04-03

How state taxes affect the ledger

North Dakota also imposes oil and gas taxes, including an oil extraction tax and a gross production tax on oil and gas, which are covered in Part 6 of this state section.

Retailers obtain a sales tax permit from the Office of State Tax Commissioner before making taxable sales and file returns monthly, quarterly, or annually as assigned by the Department based on expected liability.

Payroll records and employer reporting

Employers register for withholding and for unemployment insurance and file quarterly unemployment wage reports with Job Service North Dakota. Employers also file wage and information statements through Taxpayer Access Point, and the Tax Commissioner publishes step by step instructions for filing Forms 1099 on that system.

Income, purchases, and documentation

The general recordkeeping regulation in the recordkeeping section of this state section expressly reaches contracts, ledgers, journals, and correspondence that bear on tax liability, so vendor contracts, customer contracts, and expense correspondence in North Dakota are tax records when they support an amount on a return.

How long to retain records

The general recordkeeping regulation requires records necessary to determine correct tax liability to be maintained and produced on request, and it does not set one fixed number of years in the text reviewed. Source: https://www.law.cornell.edu/regulations/north-dakota/N-D-A-C-81-1.1-04-03

Taxpayer rights material published for North Dakota states that an assessment or refund may be issued any time within 3 years after the due date of the tax return, and within 6 years where tax is understated by more than 25 percent. Records for a return should therefore be kept at least through the applicable assessment period. Source: https://www.co.ward.nd.us/DocumentCenter/View/3982/ND-Taxpayer-Bill-of-Rights

When an industry needs additional records

Oil and gas producers must keep production, sales, and purchaser records that support oil extraction tax and gross production tax reporting, including volumes produced and sold by well or lease. This applies to operators and working interest owners in production, not to businesses generally.

Coal and other severance activities have their own production based tax reporting in North Dakota, with tonnage and sales records.

Bookkeeping in practice

The following situations illustrate how a business might organize its records. They are examples, not a determination of tax treatment for any particular business.

A Fargo retailer keeps its sales journal, purchase invoices, and the emails that document a disputed exemption in one electronic folder for the year. When the Tax Commissioner asks for records in electronic format, the retailer can produce that folder instead of only paper copies.

A small oil services company keeps a separate well file with run tickets, purchaser statements, and production reports for each month, so the amounts used for production related tax reporting can be traced to source documents.

Electronic audit records and production based activity

North Dakota businesses should be able to produce readable electronic records when requested. In resource industries, invoices alone may not explain activity, because production volumes, delivery records, and purchaser statements can support different parts of the books.

This is an accounting workflow distinction, not a claim that every business in North Dakota is subject to the same tax or filing rule. The applicable treatment depends on the actual transaction and the business activity. A bookkeeper's responsibility is to preserve the transaction evidence and classify the amounts consistently. Determining a disputed tax position or filing treatment is a separate professional judgment.

A practical monthly review for North Dakota businesses

Begin with the original source rather than the bank feed. A customer invoice, sales report, payroll register, supplier bill, or contract explains what occurred. Match it to the corresponding deposit or payment, investigate differences, and record adjustments with a clear explanation. When a state tax or payroll report is required, maintain a separate reconciliation from the ledger to the amounts included in that report. That allows an owner to compare operating results without confusing business income with taxes collected, employee withholdings, or other liabilities.

For an owner preparing to hand records to a tax professional, the useful package includes a period summary, filed return copies where applicable, the transactions supporting material adjustments, and a short list of unresolved questions. A reconciled bank account is only part of that package. The quality of the records depends on whether a reviewer can trace important figures back to their sources.

What to keep available

Maintain organized copies of the invoices, receipts, bank and card statements, payroll reports, account reconciliations, and any exemption or special program documents relevant to the business. A retention schedule should identify which law or program controls each category instead of assuming one deadline covers every record. Keep documents connected to a pending audit, claim, or dispute until the matter is resolved, and verify any destruction decision against the current applicable rule.

Paper Trail handles the bookkeeping organization, classification, and reconciliation side of this work. Tax return positions, legal interpretations, and specialized payroll classifications should be reviewed by the appropriate qualified professional.
