Yes, a late fee can be charged on any outstanding debt. It doesn't matter where the debt came from, late fees and interest charges can continue to accumulate.
In most states, a late fee is not a "sale," and therefore should not be charged sales tax.
If your loan payment is overdue, you will be charged interest that is higher than normal. You may also be charged a late fee and hurt your credit rating.

you'd be charged with late fee, so don't be LATE
Most states have laws about when a late fee can be charged. For instance, in Massachusetts, a late fee can't be charged until the rent is 30 days late, and only if the lease provides for the fee. But, if they have that in the lease, then yes, they could go back and charge retroactively.
A discount fee is a fee your lender is charging to reduce your interest rate. This fee should only be charged if your lender has to pay in order to reduce your interest rate.
Greetings fellow Washingtonian! The answer to your question is that the state does not require that you collect interest. I will assume you are talking about a real estate contract (the kind where the seller finances the property--not to be confused with a mortgage or deed of trust). If you are the seller, you are not required to charge any interest at all (my, what a nice person you are). But if the R.E.C. provides for interest, and a payment is not made, then interest will accrue on the unpaid principal. If there is a late fee provided for in the contract, then the late fee may be charged, and if unpaid, the seller may initiate foreclosure proceedings.
Late property taxes.are subject to a fee and interest, even normally provided on the bill with a "if paid on or before" amount. It makes no difference howm many times you are late, nor if you were late by a day, or paid the day the property was to be sold at auction (other than the amount of interest being charged), as to how much you would be charged for bing late on any future payment.
A penalty and interest will be charged.
