Taxable deposits: decide what the deposit covers before invoicing
Deposits can reserve time, buy materials, or prepay taxable work. Decide what the deposit covers before calculating tax and the remaining invoice total.
A deposit is easier to invoice when you know whether it is a payment toward taxable goods or services, a pass-through cost, or a timing item. Before collecting it, label the deposit, estimate tax on the right base, and carry the treatment into the final invoice.
Name what the deposit covers
Separate a schedule hold, materials prepayment, retainer for future service, reimbursed cost, and milestone payment before choosing the invoice wording. The label affects customer expectations and may affect tax timing or refund treatment.
Estimate tax on the right amount
Run the taxable subtotal separately from non-taxable deposits, reimbursed costs, shipping, or future work. If tax applies when the deposit is collected, show it clearly; if it applies later, keep the invoice note plain.
Keep quote and invoice consistent
Put the deposit amount, remaining balance, due date, tax estimate, and refund or cancellation terms in writing. Confirm state, local, contract, consumer, and accounting rules before treating a deposit as non-taxable or nonrefundable.
