2. What the rules say
Plain-English summary as of November 1, 2026. Rules change; verify current rules with the card networks, your state and your own advisor. Not legal or tax advice.
For contractors & home services
- Deposits taken before work begins can be disputed if work is delayed or not delivered. Keep signed contracts, change orders and completion records. Sources: Visa Core Rules (public); Mastercard Rules.
- Some states regulate how much deposit a home-improvement contractor may collect upfront and require specific contract terms. Check your state's contractor licensing board and attorney general. Source: Find your state attorney general (NAAG).
Surcharges, cash discounts and debit (all industries)
- Surcharges under card-network rules apply to credit cards only, never to debit or prepaid cards, even when a debit card is run as credit. Sources: Visa: merchant surcharging and fees; Mastercard: merchant surcharge rules.
- Network rules generally require advance notice to the network or your provider, disclosure at the store entrance (or first page online) and at checkout, and the surcharge shown as a separate receipt line. Network caps sit around 3% and may not exceed your cost of acceptance; confirm the current cap in the network rules. Sources: Visa Core Rules (public); Mastercard Rules.
- Some states ban or cap surcharges, and some state laws have been challenged in court, so the current rule in your state may differ from what you've read. Check your state attorney general's office and get advice before you start. Source: Find your state attorney general (NAAG).
- A cash discount (a lower price for cash or other non-card payment) is treated differently from a surcharge. Federal law lets merchants offer discounts for paying by cash, check or debit, and networks allow properly disclosed discount and dual-pricing programs. Signage and receipts still must be accurate. Source: 15 U.S.C. § 1693o-2 (discounts for cash, check and debit).
- Debit interchange for large issuing banks is capped under the Federal Reserve's Regulation II, which is one reason debit usually costs less than credit. Source: Federal Reserve: Regulation II (debit interchange).
- Card-interchange litigation: a proposed settlement between merchants and the major card networks has only preliminary court approval. Nothing changes for merchants until final approval is granted and the networks implement new rules. Source: Consumer Financial Protection Bureau.

Surcharge scenario (annual)
Formulas used
Annual fees = monthly card sales × 12 × effective rate
Fees as % of net profit = annual fees ÷ (annual sales × net margin)
Sales to replace fees = annual fees ÷ net margin
Savings = annual sales × 0.50% (or 1.00%)
Fees recovered = annual sales × (1 − lost %) × surcharge %
Net change = fees recovered − fees on surcharge + fees avoided − lost revenue × net margin
Simplified: applies the surcharge to all card sales; in practice debit and prepaid cards are excluded.
