Maryland Bookkeeping

Keeping records that support the books

Maryland law requires a vendor to keep complete and accurate records of all sales and purchases, and of the sales and use tax collected and paid. Records must adequately distinguish taxable sales and purchases from nontaxable sales and purchases. If records are inadequate, the Comptroller may compute liability by projection from available records, by a survey of similar businesses, or on any other reasonable basis, and the burden of proof is on the vendor to show tax was collected and paid correctly.

How state taxes affect the ledger

Maryland has a sales and use tax at a state rate of 6 percent, with a reduced or different treatment for certain items and a higher rate for cannabis sales to adult use consumers under the cannabis tax framework administered by the Comptroller. Maryland has no general local sales tax, although local taxes exist for specific purposes such as hotel rental taxes imposed by counties and certain excise taxes.

Maryland also has individual and corporate income taxes, employer withholding, local income tax that is collected by the state as part of the state income tax system and varies by county of residence for individuals, and a digital advertising gross revenues tax on large businesses that meet its revenue thresholds. The digital advertising tax is a gross revenues tax, but it applies only to businesses with very high global and Maryland digital advertising revenues, not to ordinary small businesses. Admissions and amusement tax is imposed locally and administered in part through the Comptroller for certain filers.

Payroll records and employer reporting

Unemployment insurance. Employers register with the Maryland Department of Labor, Division of Unemployment Insurance, file quarterly wage and contribution reports through the BEACON system, and pay contributions. Employers also file withholding with the Comptroller. Payroll records must support wages by employee by quarter for both systems, and because Maryland income tax includes a county component for individuals, withholding records must show the employee county information used.

Wage records. Maryland Wage Payment and Collection Law and Wage and Hour Law require employers to keep records of hours, wages, and deductions and to provide wage statements. The retention summary in secondary compilations lists Maryland basic pay records at three years, with federal employment tax records at four years under federal law.

When an industry needs additional records

Cannabis. Licensed cannabis businesses must keep resale certificates for business to business sales between licensees, with the buyer license number or sales tax license on the certificate, and must document medical cannabis sales with the patient or caregiver medical identification, because medical sales are not subject to the adult use cannabis tax in the same way, while amounts over a certified amount are taxable.

Construction and manufacturing. Businesses claiming an exemption for tangible personal property used directly and predominantly in production activities, or for resale or incorporation into a product for sale, must keep documentation that shows that use. Contractors and manufacturers therefore keep job and production records that support exempt purchases.

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 Maryland retailer ships a product to a customer outside Maryland. It keeps the invoice, the bill of lading, and the shipping record showing out of state delivery with its sales records for four years, so it can prove why Maryland tax was not collected on that sale if audited.

A shop buys equipment online from an out of state seller that does not charge Maryland tax. It records the purchase in its payables ledger, accrues Maryland use tax on the purchase price, reports it on its sales and use tax return through Maryland Tax Connect, and keeps the purchase invoice for four years.

Sales tax record traceability and personal property records

A Maryland sale shipped outside the state illustrates why shipping proof belongs with the sales invoice. For companies holding equipment and fixtures, the fixed asset ledger is also a practical source for business property reporting, separate from operating expense totals.

This is an accounting workflow distinction, not a claim that every business in Maryland 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 Maryland 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.
