@Blackbunny2k No, there will not be a lookback for your 2022 tax return. When you prepare your 2022 return you enter a 2022 W-2---or more than one 2022 W-2 if you worked for more than one employer in 2022. But no, there is no lookback. If you get EIC it will be based only on how much you earned by working in 2022.
