IRS Applicable Federal Rates (short, mid and long term, every compounding period, 110/120/130% variants, adjusted AFR) and the Section 7520 rate, for any month from the monthly IRS revenue ruling.

Tools

• irs_afr(month?, term?, compounding?, percent?) — the AFR tables for a month: short-term (up to 3 years), mid-term (over 3 to 9) and long-term (over 9) at annual, semiannual, quarterly and monthly compounding, with the 110%, 120% and 130% variants (150% and 175% for mid-term) and the adjusted AFRs. Filters return a single rate. Answers “what is the November 2026 mid-term AFR, annual compounding?”.
• irs_7520_rate(month?) — the Section 7520 rate for valuing annuities, life estates, terms of years, remainders and reversions, plus the same ruling’s section 382 long-term tax-exempt rate and low-income housing credit percentages.

Omit month for the newest published month. The IRS issues each month’s rates in the preceding month (typically mid-month), so next month’s rates are usually available from about the 15th. A month that has not been issued returns status: "not_yet_published" with the expected timing, never an empty result.

Every response carries ruling (e.g. “Rev. Rul. 2026-21”), data_as_of (the date the IRS published the ruling) and source.

Data sources

• IRS, Applicable Federal Rates revenue ruling — the monthly Internal Revenue Service revenue ruling that prescribes the AFR, adjusted AFR, section 382, low-income housing credit and Section 7520 rates. US federal government work, public domain. Each request reads the ruling live; nothing is copied.

Notes for maintainers: ruling numbers are not in month order (the month is read from the ruling’s own text), and the IRS listing page lags the newest ruling and mislabels months, so it is used only as a hint and later numbers are probed directly.
