IRS Applicable Federal Rates (AFR) for a month, from the monthly IRS revenue ruling: short-term (up to 3 years), mid-term (over 3 to 9 years) and long-term (over 9 years) AFRs under section 1274(d), each at annual, semiannual, quarterly and monthly compounding, with the 110%, 120% and 130% variants (and 150%/175% for mid-term) where the ruling has them, plus the adjusted AFRs (section 1288(b)). Omit month for the newest published month (the IRS issues next month’s rates mid-month). A month not yet issued returns status “not_yet_published” with the expected timing. Filter with term, compounding and percent to get a single rate. Use for family loans, installment sales, below-market loans and imputed interest. Returns the ruling number and data_as_of. Sourced from IRS, Applicable Federal Rates revenue ruling.
