An Update Notice has also been published which sets out the information which will need to be sent to HMRC quarterly using MTD-compatible software. The update information that must be provided in a quarterly update period is dependent on the relevant person’s business or businesses. HMRC will also publish the Software Notice and Notice for joint property owners in the Spring, alongside detailed guidance for each. More information is also still to be published on the digital record keeping and digital links requirements.  

MTD trial 

HMRC’s aim in 2024/25 is to expand the current MTD for income tax trial by encouraging agents to consider which clients can sign up and then to sign them up to participate in the expanded private beta testing trial in 2024/25. This month, HMRC will be sending further communications regarding the MTD for income tax trial to its entire agent mailing list. Overall, this involves a three-armed email campaign which will provide several opportunities for agents to learn more about the testing and how to sign up.  

HMRC began sending these comms last month. The next email will then be sent at launch, which will signpost agents towards the updated GOV.UK pages on compatible software, eligibility criteria, and sign-up pages.  

However, as of 10 April 2024, there still remains a very limited number of software packages that are available to participate in the trial with just five vendors confirmed, although many are in development, some of which may become available during 2024/25 or later. The Institute recommends that agents carefully consider the advantages and disadvantages of signing up clients to participate in the trial. 

HMRC has also now published detailed guidance in respect of the penalty regime which will apply when trial participants testing MTD for income tax make late submissions. These changes to penalties only apply during the testing phase and must be agreed to before a taxpayer can be signed up to participate in the trial. 

Broadly, agents who wish to develop a list of clients that are eligible to join the expanded trial in 2024/25 should follow the below steps when considering their options: 

• Step 1 - assess client suitability – this can be done by using an eligibility checker to triage/filter which clients are eligible to participate. 

• Step 2 - discuss this with the client and get their agreement before going back into the service to actually sign them up. 

Note that full client approval is needed to then progress onwards and sign the client up to participate. 

The cost of MTD 

HMRC has also sent the following message about the cost of MTD: 

“We have also published an updated Tax Information and Impact Note (TIIN), to accompany the Regulations. Among other impacts, this sets out the latest projected exchequer benefits, operational costs, and customer cost impacts of MTD ITSA. Since we published the last TIIN in September 2021, we have updated the assumptions within the customer costs model. We have also reviewed the methodology and cost assumptions with tax professional bodies and the Administrative Burdens Advisory Board (ABAB).  

We recognise that there are transitional costs for business in moving to MTD. Both these, and the continuing costs will vary depending on factors such as size, complexity, and digital capability of the business.  

Continuing costs  
 
Once implemented, MTD expansion is estimated to increase the total net continuing costs of complying with the tax system for all mandated businesses by £196m per year - about £110 per year, per business. This compares to a previous net cost estimate in 2021 of £152m per year, or about £35 per year, per business. A range of assumptions have been updated since the last estimates, including uplifting costs and wage rates in line with inflation, re-examining time spent undertaking tasks, reviewing the price of software products, and using the latest evidence on record keeping practices.  

Transitional costs  
 
The decision to increase the previous £10,000 income threshold to £30,000 means there is a smaller, more digitally able population within scope. We have therefore reduced our per-business estimate for the transitional costs, in comparison to the estimates published in our last TIIN.  

We estimate the transitional costs for all mandated businesses will total £561m, which equates to about £320 per business. This compares to £1,383m (about £330 per business) in our 2021 figures. Although the reduction in population size means transitional and continuing costs are lower overall than previously estimated, we recognise that the continuing customer costs per business are significantly higher. We are confident that these updated estimates in the TIIN present a more granular and informed position. These remain estimates, not a definitive statement of costs, but we have used the most robust methodology possible to estimate and set them out in a realistic and straightforward way. ABAB have also advised that they are comfortable with the revised assumptions.  

We also know that, whilst there are costs in using MTD, we expect there to be benefits in the future. For example, using compatible software will reduce opportunities for error and help businesses and landlords get their tax affairs right first time. Evidence from MTD VAT also points to the use of compatible software encouraging businesses to digitalise other elements of their business due to productivity benefits. We are committed to extending these benefits to business, self-employed individuals and landlords who are registered for Self Assessment from April 2026. The government will continue to keep the decision on whether to mandate businesses and landlords with income below £30,000 to use MTD ITSA under review, although this group can still sign up voluntarily.”
