Forward-month deadline list

August 2026 has IRS business and payroll checkpoints, but no OPM-listed federal holiday.

Last verified June 16, 2026

This page is built for readers planning ahead from June 2026. It summarizes August 2026 federal deadline signals from official IRS, OPM, and Federal Reserve sources without deciding whether a specific business, taxpayer, employer, vehicle owner, bond issuer, or wagering operation is covered by a rule.

August 2026 federal dates at a glance

Date Official-source item What to verify
August 5, 2026 IRS lists a semiweekly payroll deposit item for payments on July 29-31 if the semiweekly deposit rule applies. Whether the employer is on the semiweekly rule and whether the covered payment dates match the payroll record.
August 7, 2026 IRS lists a semiweekly payroll deposit item for payments on August 1-4 if the semiweekly deposit rule applies. The employer deposit schedule and actual payroll dates.
August 10, 2026 IRS lists Form 941 for the second quarter if all required payments were timely deposited, and also lists July tip reporting. Whether the timely-deposit condition applies and whether an employee has July tips of $20 or more to report.
August 15, 2026 IRS lists Form 8038, 8038-B, 8038-G, and 8038-TC for bonds issued in April, May, or June 2026. The bond type, issue period, form instructions, and any issuer-specific counsel or filing instruction.
August 17, 2026 IRS lists monthly payroll-tax deposit timing for July payments when the monthly deposit rule applies. Whether the monthly deposit rule applies and whether Social Security, Medicare, and withheld income tax records match the period.
August 19-28, 2026 IRS lists additional semiweekly payroll deposit items for August payment windows. Payment windows, deposit schedule, and EFTPS scheduling cutoffs.
August 31, 2026 IRS lists Form 730 for wagers accepted during July and Form 2290 for vehicles first used during July. Whether the wagering-tax or heavy-vehicle-use-tax rule applies, and whether the activity happened in July.

No August 2026 federal holiday

OPM’s 2026 federal holiday schedule moves from the July 3 Independence Day observance to Labor Day on Monday, September 7, 2026. The Federal Reserve K.8 schedule also lists Labor Day on September 7 and no August holiday. That means an August 2026 “federal holiday closure” page would be weaker than an August IRS deadline page unless the page is specifically explaining that there is no August federal holiday.

Private schools, employers, state governments, local governments, banks, and service providers may still have August closures or back-to-school dates, but those are not federal dates. This page stays inside the federal-source boundary so the information remains verifiable and does not imply a local or employer-specific schedule.

How to use the August list

  • Start with the IRS third-quarter tax calendar and confirm the date, form, payment period, and rule language.
  • Separate payroll deposit dates from form filing dates; they are not the same type of action.
  • For Form 941 timing, confirm whether the timely-deposit condition actually applies before relying on the August 10 date.
  • For Form 2290 and Form 730, confirm the July activity or first-use period before using the August 31 date.
  • Use OPM and Federal Reserve sources only for federal holiday context; they do not decide private bank or employer hours.

Planning boundary

This is a forward-looking August 2026 list

As of the June 2026 planning window, this cluster starts with August 2026 dates. It follows the same forward-month rule as the July pages: publish dates readers can still plan for, and avoid standalone lists that begin with deadlines already in the past.

August 2026 does not have an OPM-listed federal holiday. The useful August pages are therefore centered on IRS third-quarter calendar items, with a note that the next federal holiday after the July observance is Labor Day on September 7, 2026.
