Where each one falls short

Documented limitations, not opinions. Every one is a constraint you would hit in normal use.

Affirm

  • Longer instalment plans carry real interest, up to roughly 36 percent APR depending on the retailer, item and applicant, which is a genuine borrowing cost that the buy now pay later framing can obscure for shoppers who do not read the terms shown before accepting.
  • Even with no late fees, Affirm reports many loans to credit bureaus, so a missed or late payment on a longer plan can affect a credit score in a way the marketing around interest-free short plans does not prepare shoppers for.
  • Approval and APR both vary by individual loan, so the same shopper can be offered interest-free terms on one purchase and a high APR on another, making the cost unpredictable until checkout.
  • Merchants pay a transaction fee to offer Affirm at checkout, a cost typically built into retail pricing, so shoppers who pay by other means still indirectly subsidise the option even if they never use it.
  • The Affirm Card blurs the line between buy now pay later and a general-purpose credit card, and using it for everyday spending on interest-bearing terms can compound borrowing cost in a way a single point-of-sale purchase would not.

IRS2Go

  • It only covers federal IRS matters, so it is no help for state tax filing or refund status, which is a separate system in every state.
  • Refund status information is not real time and can lag actual processing, which frequently confuses users expecting instant updates.
  • It is not a full tax filing tool, so users still need separate tax preparation software or a preparer to actually file a return.
  • Its usefulness is entirely seasonal, concentrated around the US tax filing period each year, with little reason to open it the rest of the time.
  • As with any official government app, it has been targeted by lookalike phishing apps and messages impersonating it, so users need to confirm they have the genuine IRS-published app.
