Verified January 2027 dates
This page is built for readers planning beyond the current month. It focuses on dates that can be checked against official federal sources now, rather than guessing at a future IRS annual calendar that has not been used for this batch.
| Date | What it covers | Status from today | Official-source boundary |
|---|---|---|---|
| January 1, 2027 | New Year’s Day federal holiday. | Future date | OPM lists the 2027 federal holiday date. Federal Reserve K.8 also lists New Year’s Day for 2027. |
| January 15, 2027 | Fourth 2026 estimated tax payment for calendar-year individual filers using the regular estimated-tax schedule. | Future date | IRS Form 1040-ES for 2026 lists the fourth payment date as January 15, 2027. |
| January 18, 2027 | Birthday of Martin Luther King, Jr. federal holiday. | Future date | OPM and Federal Reserve K.8 list January 18, 2027 for the 2027 holiday schedule. |
| February 1, 2027 | Follow-up date tied to the January 15 estimated-tax payment exception. | Next cycle follow-up | IRS Form 1040-ES says the January 15 payment may not be required if the 2026 return is filed by February 1, 2027 and the entire balance is paid. |
| March 1, 2027 | Follow-up date for the farming and fishing estimated-tax rule described in Form 1040-ES. | Next cycle follow-up | IRS Form 1040-ES describes March 1, 2027 as a filing/payment alternative for qualifying farming or fishing income cases. |
What to prepare before January starts
- Treat January 1 and January 18 as federal holiday planning dates, then confirm any private employer, school, bank branch, or local office schedule separately.
- For the January 15 estimated-tax date, gather 2026 payment records, withholding records, income records, and the current IRS payment instructions before acting.
- If February 1 or March 1 might matter, verify the actual IRS rule text and your own situation before relying on a timing shortcut.
- Keep state tax, local tax, payroll, and business filing calendars separate. This page only covers the federal items listed above.
What this page does not decide
This calendar does not decide whether you owe estimated tax, whether a penalty applies, whether a payment exception fits your facts, or whether a holiday changes a private organization’s schedule. It also does not replace IRS forms, account notices, tax software, or professional review.
For 2027 tax planning, the key limitation is important: the IRS source used here is the 2026 Form 1040-ES package. That source verifies early 2027 dates connected to the 2026 estimated-tax cycle. It is not a complete 2027 individual income-tax calendar.
