IRS Rules for Tax Underpayment Penalty
I need a clarification of the IRS rules for tax underpayment penalty. If he is getting a refund on his 2021 return, (having paid estimated taxes last year), TurboTax indicates that he doesn't technically need to pay estimated taxes for tax year 2022. However, he is expecting a 15% increase in taxable income in 2022, and without paying estimated taxes, he is not likely to have paid least 90% of the tax that will be due on the 2022 return.
According to IRS rules, can we be confident that he will not be penalized if he does not pay estimated taxes?
