The  Internal Revenue Service today urged those “who paid too little tax in 2022 to make a fourth-quarter payment on or before January 17 to avoid an unexpected potential tax bill or penalty when they file in 2023.”

The IRS statement added that “most income is taxable. This includes unemployment income, refund interest and income from the gig economy and digital assets. When estimating quarterly tax payments, taxpayers should include all forms of earned income, including part-time work, side jobs, or the sale of goods.

Also, various financial transactions, especially late in the year, can often have an unexpected tax impact. Examples include year-end and holiday bonuses, stock dividends, capital gain distributions from mutual funds, stocks, bonds, virtual currency, real estate, or other property sold at a profit.
