Each year, various limits affecting income tax preparation and planning change. Some changes commonly occur each year as a result of inflation indexing, while others occur because of new legislation or the sunsetting of existing law. This course will examine the tax changes affecting 2025 as a result of passage of the H.R.1, an act to Provide for Reconciliation, and the inflation-changed limits effective for 2025 that are more significant from the perspective of an income tax preparer. Some context will be supplied, as appropriate, to assist readers in understanding the changes.
