Credit card fees on contractor bills: what's allowed and what's normal

Short answer

Many contractors can legally add a credit card surcharge, but it is limited. In the US, Visa caps surcharges at 3% and requires them to be disclosed before payment, and some states restrict them. In Canada, surcharges must be disclosed and are capped (Visa and Mastercard rules limit them to the merchant's cost, up to 2.4%), and Quebec's consumer law bans them. Surcharges generally cannot be added to debit card payments.

Card processing costs businesses roughly a few percent per transaction, so some pass that cost on. A disclosed surcharge within the rules is normal. A surprise percentage, a fee above the network cap, or a fee on debit is worth questioning.

Rules change and differ by location and card network. This guide is educational, not legal advice.

QuebecSurcharges on credit card payments are not permitted under consumer law.The Office de la protection du consommateur covers this.

2. Surcharge vs cash discount

A surcharge adds a fee for paying by card. A cash discount lowers the price for paying another way. They can end up at a similar total, but the rules differ. Ask which one your contractor uses, and get the total for each payment method before you pay.

Large job? Ask early

A 3% fee on a $20,000 project is $600. On large jobs, ask at the quote stage whether e-transfer, cheque or ACH avoids the fee, and whether paying by card still makes sense for purchase protection.

3. What to say

Questioning a card fee

  1. 1.“My bill shows a [x]% card processing fee. Was this disclosed before payment?”
  2. 2.“I'm paying by [debit / credit]. Can you confirm the fee is within the card network's limits?”
  3. 3.“What would the total be if I pay by [e-transfer / cheque / ACH]?”

The one thing to remember

Disclosed, capped, credit only

A legitimate card surcharge is shown before you pay, stays within the network cap, and is not applied to debit.

Common questions

Is a 4% credit card fee legal?

In the US, Visa caps surcharges at 3%, and Canadian network rules cap them lower. A higher fee is worth questioning.

Can a contractor charge a fee for debit?

Card network rules generally prohibit surcharges on debit and prepaid cards in both the US and Canada.

Can I report an improper surcharge?

You can contact your card issuer, your state attorney general, or in Canada the Financial Consumer Agency of Canada or your provincial consumer office.
