hi, I work at the IRS. given the changes that are made to federal tax returns every year, I would say that this game would not help you in filing your 2023 tax return accurately. however, the IRS itself offers programs for taxpayers under a certain income to get their returns filed either by a volunteer preparer or by a computer program. assuming MSCHF doesn't update the game for 2023, I would recommend checking those out for your upcoming tax prep needs!
