The filing deadline for 2019 City of Portsmouth income tax returns has been extended from April 15 to July 15, 2020 for individuals and businesses. This extension coincides with Federal IRS Guidelines the US Treasury Department issued for special tax filing and payment relief for individuals and businesses in response to the Coronavirus (COVID-19) crisis.
All residents of the City of Portsmouth (18 years of age and older) are required to file a city income tax return with the City Tax office on an annual basis, even if no tax is due. Non-residents who have income derived within the City of Portsmouth and for whom the tax is not withheld by their employer must file a Portsmouth City income tax return and pay City income tax.
Penalties and interest will begin to accrue on any remaining unpaid balances on July 16, 2020. You will automatically avoid interest and penalties on the taxes paid by July 15, 2020. Taxpayers who are unable to file by the July 15, 2020 deadline must submit Federal Extension Form 4868, along with their request for extension.
