The purpose of this legislation, known as the Taxpayer Transparency and Notice Act, is to improve communication between the Internal Revenue Service (IRS) and taxpayers who have unpaid tax balances. The main objective is to ensure that these taxpayers receive timely and clear information about their debts, including potential penalties and interest, to encourage them to address their tax obligations. Key provisions of the Act require the IRS to send quarterly notices to taxpayers with unpaid balances, rather than just once a year as was previously mandated.
