Calculate and add sales tax

Calculate and add sales tax to the outstanding invoice 2026-045 for client Maple Street Co. based on Vermont tax rules. The invoice total before tax is $2,800 for consulting services; apply the 6% sales tax where applicable, add a line that says Sales Tax (VT 6%), update the total, and send the revised invoice to rachel@maplestreet.co with a note explaining the tax addition and the effective date of the change.

Before I apply sales tax to this invoice, make it easy for the client to accept: put the tax charge immediately under the subtotal with the rate and jurisdiction shown, explain in one sentence why tax applies to this service, and flag any customers on the invoice who are marked tax-exempt or have an exemption certificate that would block the charge.

Invoice 2026-045 for Maple Street Co. is due and I need to add 6% Vermont sales tax, but the client sometimes presents an exemption for similar services. I don’t know whether they have a valid exemption on file or whether charging now will create a dispute. What is the most likely cause of the uncertainty and what single action should I take right now to avoid conflict and keep the payment on schedule?

We repeatedly generate invoices and then have to reissue them after discovering tax applies or a client’s exemption certificate is missing. That wastes time and annoys clients. What process change would prevent reissuing invoices, who should be responsible for verifying tax status before billing, and what routine check should catch missing exemption certificates before an invoice is sent?
