If you follow the link in this TX-UK section of the OT website, to Technical Articles, it will take you to the ACCA website where you should then look at the FA 2020 article which identifies any changes brought in by FA 2020. You will see that there are no changes for VAT and just one change in the IHT section with an increase in the residence nil rate band. If you use the OT Study Notes and Lectures then the only other essential material purchase is a FA 2020 Exam / Revision Kit from an approved ACCA provider.
