Cambridge’s online payment system is fee-based. For large bills, the payment method can make a major cost difference.

|---|---|---|
| Credit card | 2.95%, minimum $1.95 | Can be expensive for real estate tax bills. |
| Debit card | 2.95%, minimum $1.95 | Do not assume debit is cheaper; verify checkout total. |
| Electronic check / EFT | $0.40 flat fee | Usually the lower-cost online option for larger bills. |
| Phone payment | Additional $0.95 for payments | Balance checks are listed as free; payment has extra fee. |
| Mail / drop box | No online convenience fee | Payment timing risk is higher because postmark is not accepted. |
Fee decision tip
For a $2,000 bill, a 2.95% card fee is much larger than a $0.40 electronic check fee. Always review the final payment screen before submitting.

If the bill is no longer current or the amount differs from the original notice, contact Finance before paying an old amount.
