View in ChatGPT directory

Tax Filing Center gives general information about federal business tax filings for businesses, plan sponsors, fiduciaries, and individuals making large gifts.

  • Estimates the PCORI fee for a self-insured health plan or insurance policy from the plan-year end and average covered lives, with the Form 720 due date.
  • Looks up the quarterly Form 720 due date, moved for weekends and legal holidays, and explains the late-filing penalty rule.
  • Looks up current Form 720 federal excise tax rates, such as air transportation, indoor tanning, fuels, heavy truck sales, foreign insurance, and the petroleum Superfund tax, and notes taxes that have expired.
  • Finds the original and extended due dates for Forms 1065, 1120, 1120-S, and 1041 under the automatic Form 7004 extension.
  • Finds federal Form 1041 and state fiduciary return due dates, extension rules, and filing thresholds for all 50 states and D.C., including states with no fiduciary income tax.
  • Checks whether a gift tax return (Form 709) is required using the annual, non-citizen spouse, and lifetime exclusion amounts, and gives its due date.
  • Identifies the right Form 8849 schedule for an excise tax refund claim, with minimum amounts and filing windows.

Limitations: results are estimates and general tax information, not tax or legal advice; confirm with the current IRS or state instructions or a tax professional. The plugin does not file returns, take payments, sign in to accounts, or store personal information. Filing is done separately at taxfilingcenter.com. Tax Filing Center is operated by Tax Filing Center, LLC and is not part of or affiliated with the IRS or any government agency.
