US Treasury, IRS extend federal tax filing and tax payment deadline

March 21, 2020

In response to the coronavirus crisis (COVID-19), the US Treasury  and IRS have officially extended the 2019 tax year federal tax filing  and payment deadline to July 15, 2020.

This change was officially announced with the release of IRS circular IR-2020-58,  published by the Internal Revenue Service on March 21, 2020. No  additional forms are required for taxpayers to elect to file their  federal tax returns by July 15, 2020.

Despite the filing deadline being extended to July 15th, the IRS  and our firm urge tax payers who are owed refunds to electronically file  their tax returns with their tax preparer earlier than July 15th in  order to receive refunds as soon as possible. Filing electronically with  direct deposit is the quickest way to receive refunds. Most tax refunds  are still being issued within 21 days.

Individual taxpayers who need additional time to file beyond the  July 15 deadline, can request a filing extension by filing a Form 4868  through our firm. Businesses as well who need additional time may file a Form 7004 through our firm's tax professionals.

The actions taken by the US Treasury and the IRS are welcome news and offer  some relief as we all await a final reprieve from the COVID-19 crisis. As  many of you are wisely heading CDC social distancing guidelines, BAS  Accounting Services, CPA firm as well has implemented measures and  technology to safeguard our clients during the crisis.
