What is a typical late payment penalty?

Common penalties range from 1-2% per month (12-24% annually). Many B2B contracts specify 1.5%/month. Some jurisdictions cap the maximum penalty rate.

Is a flat late fee or percentage better?

Percentage-based fees grow with the amount and delay, making them more proportional. Flat fees are simpler but may be excessive for small invoices or insufficient for large ones.

Are late payment penalties tax-deductible?

Late payment penalties are generally not deductible for the payer. For the recipient, they are typically taxable income. Consult a tax professional for your specific situation.

What is the maximum legal late fee?

Maximum late fees vary by jurisdiction. Many US states limit consumer late fees to 5% or $15-25. Commercial contracts have more flexibility but penalties must be reasonable.

When should I start charging late fees?

Late fees typically apply after the payment due date (Net-30, Net-60, etc.). Best practice is to clearly state late fee terms in the original invoice and contract.
