The Internal Revenue Service reminds taxpayers to protect their personal and financial information throughout the year and watch out for IRS impersonation scams, along with other schemes, that try to trick people out of their hard-earned money.

With the new tax season starting this week, the IRS reminds taxpayers to be aware that criminals continue to make aggressive calls posing as IRS agents in hopes of stealing taxpayer money or personal information.

Here are some telltale signs of a tax scam along with actions taxpayers can take if they receive a scam call.

The IRS is sending letters to millions of parents who received advanced Child Tax Credit payments last year. But Monday, they warned some letters may include incorrect information.

The Treasury Department and the White House relaunched a revamped version of the ChildTaxCredit.gov site Monday to coincide with the start of tax season, adding new features to help with filing taxes and accessing the full amount of unpaid credits.

The Internal Revenue Service will require taxpayers to take selfies and verify their identities through ID.me to access online accounts starting this summer.

National Taxpayer Advocate Erin Collins told lawmakers last Wednesday that 2021 was "the most challenging year taxpayers and tax professionals have ever experienced" and that she was "deeply concerned" about the upcoming filing season.

In her annual report to Congress, Collins said 2021 "provided no shortage of taxpayer problems," and more await the 2022 filing season.

The Internal Revenue Service announced that the nation's tax season will start on Monday, January 24, 2022, when the tax agency will begin accepting and processing 2021 tax year returns.

The January 24 start date for individual tax return filers allows the IRS time to perform programming and testing that is critical to ensuring IRS systems run smoothly. Updated programming helps ensure that eligible people can claim the proper amount of the Child Tax Credit after comparing their 2021 advance credits and claim any remaining stimulus money as a Recovery Rebate Credit when they file their 2021 tax return.

Americans who were eligible for the third stimulus check or the monthly advance child tax credit in 2021 need to be on the lookout for two letters from the IRS before they file their taxes in 2022. They will be arriving at the end of January.

People receiving these letters should keep them. Please do not throw them away.

These letters should be submitted when preparing your 2021 federal tax return. Using the information in these letters when preparing a tax return can reduce errors and delays in processing.

The City of Philadelphia Department of Revenue launched a new tax filing and payment website on November 1, 2021.

Effective November 1, all taxpayers – including those who previously filed an annual Wage Tax reconciliation form by paper, via the previous eFile/ePay site, through ACH debit, or by phone – must use the new Philadelphia Tax Center website. No other filing or payment methods are permitted.
