Employer PAYE new recurring Direct Debit functionality

  • HMRC will shortly introduce a recurring Direct Debit option for employers which ensures a consistent set of payment options are available to all customers.
  • This service was originally to be available in mid to late August 2022 however there have been some delays and HMRC now expect it to be available in early October 2022.
  • Once the new service is available, there will be a new link which will allow employers to set up a Direct Debit via the employers’ liabilities and payments screens in the business tax account (BTA).
    • This will allow your clients to set up a recurring Direct Debit instruction (unless they cancel it), authorising HMRC to collect directly from their bank account based on their return submissions.

See Employer Bulletin: August 2022 for more details

New powers for naming tax avoidance promoters

  • HMRC publishes lists of those involved in the supply of mass-marketed tax avoidance schemes and details of the schemes they are selling. See Current list of named tax avoidance schemes and promoters, enablers and supporters.
  • Following Finance Act 2022 HMRC can now name connected persons including individuals involved in promoting tax avoidance such as directors, company officers and those behind these schemes.
  • In August 2022, HMRC used these new powers for the first time to name two suspected tax avoidance promoters, as well as the directors of these companies. More publications under this new power are planned and HMRC will update the list as cases progress.
  • This is not a complete list of all tax avoidance schemes currently being marketed or of all promoters, enablers and suppliers. There are other schemes, promoters, enablers and suppliers HMRC cannot publish information about.

Preparing for the new tax year basis: Income Tax Self Assessment

  • The rules HMRC use to work out sole traders’ and partners’ profits for Income Tax Self Assessment return are changing for many businesses for 2023-24 onwards. 
  • Only taxpayers with an accounting date other than 31 March/5 April are affected by the change.
  • From April 2024, businesses will be taxed on profits for the tax year and not, as now, the profits for the accounting period ending in a tax year. 
  • From 2024-25 onwards where accounting periods are different from the tax year end, the taxable profits will be apportioned between the two accounting periods that straddle the tax year.
  • The tax year 2023-24 is a transition year when self-employed businesses will move to the new way of calculating taxable profits for the tax year.
  • This transition year will allow all businesses currently trading, regardless of the accounting end date, to use any overlap relief due.
  • From 2023-24, some businesses might have to use provisional figures on their returns.
  • Where a business’s accounting date is changed in the tax year 2022 to 2023, the current change of accounting date rules will apply. When a business decides to change its accounting date from the tax year 2023 to 2024 onwards, these rules will not apply and a change can be made regardless of past changes.

Economic Crime Levy for Anti-Money Laundering (AML) regulated businesses

  • The Economic Crime Levy (ECL) was introduced in Finance Act 2022 as part of the government’s plan to develop a sustainable resourcing model for economic crime reform.
  • Individuals, partnerships (including LLPs) and companies who carry on an AML-regulated business at any point in a financial year and have UK revenue of at least £10.2 million, need to pay the ECL.
  • For UK resident entities, UK revenue is turnover for the accounting period plus amounts not included in turnover which is recognised as revenue in accordance with Generally Accepted Accounting Practice (GAAP). Revenue of a non-UK permanent establishment is excluded.
  • The amount of ECL charged is determined by the entity’s UK revenue in the financial year.
  • Payments must be made by 30 September following the end of the financial year so the first payments are due by 30 September 2023.

  • HMRC has introduced a new process to allow agents to report and pay using the Capital Gains Tax (CGT) UK property disposal online service on behalf of clients who are digitally excluded.

The process is:

  • Client gives the CGT on UK Property Account reference to their agent to begin the agent-client authorisation process.
  • Agent logs into Agent Services and selects ‘Ask your client to authorise you’.
  • Agent enters their client’s CGT Account reference, creating an invitation link.

Student loans

This is for agents dealing with payroll.

  • Employers are responsible for dealing with Student Loan (SL) and Postgraduate Loan (PGL) deductions through the payroll via RTI including:
    • Paying these to HMRC alongside tax and NICs.
    • Giving employees details of the deductions on their wage or payslip, and P60 certificate.

Common errors identified on RTI were:

  • No SL and PGL deductions are taken, despite HMRC sending a start notice.
  • SL and PGL deductions are taken and recorded under the wrong loan or plan type.
  • Deductions continuing after a stop notice has been issued.

Tips for getting it right:

If you are managing payroll on behalf of an employer, please ensure that you:

  • Action start and stop notices on the next available payday from receipt.
  • Always check the start notice, even if deductions are already being taken.
  • Apply the relevant loan and plan type to the payroll, this can be found on the start notice, by asking the employee or by checking the starter checklist for new employees. If the employee does not know their loan or plan type, they can log into their Student Loans Company account.
  • Apply the correct thresholds and rates for the relevant loan or plan type.
  • Take extra care to ensure entries are recorded accurately on the employee's RTIFPS.

Making Tax Digital

Change in how customers tell us about errors on their VAT returns: new digital G-Form.

  • The new G-form is an online form is for all customers who wish to submit a VAT Error Correction Notice (ECN). Once submitted, a copy of the digital form will be captured into the Digital Mail Service (DMS) and processed as it is currently.
  • There will be no change to the way HMRC currently processes VAT Error Correction Notices.

Benefits of the new G-Form:

The new G-Form will streamline the process for customers, making it easier to tell HMRC about errors on their VAT returns. It will enable customers to:

  • Upload supporting documentation.
  • Provide explanatory notes.
  • Save the form allowing them to complete it later.
  • Receive a confirmation of submission with a reference number.

It also will help to reduce mistakes through built-in validation and auto-calculations.

The Trust Registration Service

Deadlines for registering a trust with HMRC

  • The deadline for registrations for most trusts on the Trust Registration Service was 1 September 2022. Any trusts who have not yet registered and are required to do so should register as soon as possible.
  • Trusts that need to register from 1 September 2022 must do so within 90 days.
  • No penalties will be charged for failure to register or late registration of a trust unless that failure is deliberate, in which case the trustee may be liable to a penalty of £5,000.

See Trust Registration Service

Corporation Tax repayments

  • HMRC have introduced a change to help Corporation Tax (CT) companies claim repayments faster if they have waited more than eight weeks since making their claim.
  • HMRC aim to respond to all progress chasing calls for CT repayments within one working day where the company has waited more than eight weeks since submitting its claim with cases to be escalated to a technical adviser in real-time.
  • Where a technical adviser cannot respond in real-time, the company will be added to a list to be worked on by a technical adviser within one working day.

The change benefits companies and agents with complex cases and those who are in receipt of a high-value repayment. It significantly reduces the number of times a company/agent will have to contact HMRC to progress their Corporation Tax repayment claim.
