Lenders are within their rights to file reports with the three major credit bureaus—Experian, Equifax and Transunion—if you fail to repay your loan. This negative remark will lower your credit score and may make it impossible for you to obtain short term loans or other forms of credit in the future. However, once you have repaid your debt to your lender in full, this will be reported to the credit agencies and the negative remark will be removed from your credit history.
You’ll have to repay the loan on your next payday, which can be up to 30 days from the date you get the loan. Most lenders require your bank account information so they can debit the repayment amount directly on the given due date. If you apply in-store, you can provide a post-dated check at the time of application. Some lenders allow you to make early repayments via credit cards, MoneyGram and Western Union.

A report from the Federal Reserve Bank of New York concluded that, "We ... test whether payday lending fits our definition of predatory. We find that in states with higher payday loan limits, less educated households and households with uncertain income are less likely to be denied credit, but are not more likely to miss a debt payment. Absent higher delinquency, the extra credit from payday lenders does not fit our definition of predatory."[24] The caveat to this is that with a term of under 30 days there are no payments, and the lender is more than willing to roll the loan over at the end of the period upon payment of another fee. The report goes on to note that payday loans are extremely expensive, and borrowers who take a payday loan are at a disadvantage in comparison to the lender, a reversal of the normal consumer lending information asymmetry, where the lender must underwrite the loan to assess creditworthiness.
