Use this page to prepare invoices for bookkeeping, tax preparation, advisory, payroll support, audit support, and other accounting services. Accountant invoices commonly use fixed routine-service fees, hourly rates, fee ranges, or initial consultation fees, depending on the engagement. The finished invoice should tell the client exactly which service was performed, the period covered, the fee basis, the amount due, and the payment terms.
A practical accountant invoice also supports your own records. IRS Publication 583 lists invoices among supporting documents that record business transactions and show amounts and sources of gross receipts. For ordinary United States private-sector invoices, no prescribed federal invoice form applies. Content is mainly a recordkeeping, contract, and client communication matter, with sales-tax treatment handled under state and local rules where applicable.
A complete accounting invoice should identify your firm, the client, the invoice number, invoice date, due date, service period, line items, rates or fixed fees, expenses, taxes if applicable, discounts, payment terms, and remittance details. A line item can read: "Monthly bookkeeping, March 2026, fixed fee, $650" or "Tax notice response, 3.5 hours at $175 per hour."
Sales tax does not follow a single national VAT or GST invoice regime in the United States. State and local sales and use tax rules decide whether tax applies, based on nexus, product or service taxability, and place of sale. Service taxability varies by state and service type. California generally taxes retail sales of tangible personal property and only some service or labor charges, while Texas defines 16 broad categories of taxable services.
Accountant invoices should match the fee language the client accepted. For IRS matters, Circular 230 recognizes written fee schedules that state fixed fees for routine services, hourly rates, fee ranges for particular services, and initial consultation fees. Published fee information for IRS matters where costs may be incurred must state whether clients are responsible for those costs.
Several professional rules affect how tax and attest invoices are handled. Circular 230 prohibits unconscionable fees in matters before the IRS. AICPA rules bar contingent fees for preparing an original or amended tax return or refund claim, and Circular 230 restricts contingent fees for IRS matters with specific exceptions. For attest clients, significant unpaid fees tied to services provided more than one year before the current-year attest report date create independence threats.
A free invoice works well for a single return, a one-time advisory call, or a fixed monthly bookkeeping charge. It gives you a clean document, a due date, and a record of the service billed. It also works when the client relationship is simple and the invoice does not need to pull time from multiple staff members, matters, or recurring projects.
A managed workflow becomes necessary when tracked billable time and expenses feed the invoice. Everhour Billing & Invoicing can convert uninvoiced time and expenses into client invoices, calculate amounts from rates while excluding non-billable tasks, apply client defaults such as taxes, discounts, and payment terms, and export invoices to QuickBooks Online, Xero, or FreshBooks with status syncing back to Everhour.

Use the billing basis stated in the engagement terms. Accounting invoices commonly use a fixed routine-service fee, an hourly rate, a fee range, or an initial consultation fee. For IRS matters, Circular 230 recognizes those fee schedule formats, and published fee information involving possible costs must state whether the client is responsible for those costs.
No. The United States does not use a national VAT or GST invoice regime, so there is no United States VAT or GST registration number for invoices. Sellers that make taxable sales may need state-level sales-tax registration, such as a California seller's permit for retailers engaged in business in California selling taxable tangible personal property.
AICPA rules bar members in public practice from preparing an original or amended tax return or claim for tax refund for a contingent fee. Circular 230 also restricts contingent fees for IRS matters, with exceptions for specified examinations or challenges, refund claims tied solely to statutory interest or penalties, and judicial proceedings under the Internal Revenue Code.
Client-provided records may not be withheld for nonpayment of retrieval, copying, or shipping fees under AICPA guidance, and required records should generally be made available no later than 45 days after request. Member-prepared records or work products may be withheld when fees are due for that specific work product, subject to stricter state or federal requirements.
No. State and local sales and use tax rules control whether a service is taxable, and service taxability varies by state and service type. California generally taxes retail sales of tangible personal property and only some service or labor charges. Texas defines 16 broad categories of taxable services. Apply the rule for the relevant jurisdiction and service.
