My client made 2 partial payments of tax owed by credit card, due to limits by his card provider for amounts authorized on each transaction.  Still has balance owing, but discovers IRS limits to 2 payments only. The reason he is paying by card is because he is a foreign non-resident who temporarily worked in the US during 2018. He has no US bank account, no US checks and no prior filing history which are all required for Direct Pay, EFTPS and mailing in a check.  How else can he pay the balance due? Any ideas?
