Preparing for MTD ITSA Deadlines: A Complete Guide for Small Business Owners

With Making Tax Digital (MTD) for Income Tax Self Assessment (ITSA) now in full effect, small business owners and landlords must understand how to prepare for MTD ITSA deadlines. Failing to meet these requirements can result in penalties, stress, and administrative burdens. At BNA Consulting, we help UK businesses stay compliant and make the most of digital tax reporting.

Whether you are a sole trader, landlord, or small business owner, this guide will walk you through everything you need to know to prepare for MTD ITSA deadlines, including filing schedules, required software, and best practices to stay on track.

What is MTD for ITSA?

MTD for ITSA is the UK government’s initiative to modernize tax reporting. From April 2024 onwards, most UK businesses with an annual income over £50,000 are required to submit their income tax data digitally using HMRC-compatible software. The aim is to simplify record-keeping, reduce errors, and ensure timely submission.

Key points include:

  • Digital Record Keeping: Businesses must keep digital records of all income and expenses.
  • Quarterly Updates: Reporting income and expenses in quarterly updates rather than just once a year.
  • Final End-of-Year Submission: A final declaration to HMRC summarising income and allowable expenses.

Preparing early ensures you won’t be caught off guard by deadlines and penalties.

Understanding MTD ITSA Deadlines

Staying on top of deadlines is crucial. Missing MTD ITSA deadlines can lead to fines and interest charges. Here’s a breakdown of important dates:

  1. Quarterly Updates: Must be submitted within one month of the end of each quarter.
  2. End-of-Year Declaration: The final summary report is due by 31 January following the end of the tax year.

Tip: Using HMRC-compatible software simplifies tracking deadlines and reduces the risk of missed submissions.

Steps to Prepare for MTD ITSA Deadlines

1. Register for MTD for ITSA

Before you can submit your digital updates, you must register with HMRC. This ensures your business is recognized under the MTD scheme and can access digital filing tools.

2. Choose HMRC-Compatible Software

Not all accounting software is MTD-compatible. Select software that allows:

  • Real-time tracking of income and expenses
  • Seamless quarterly submissions
  • End-of-year summary reports

Popular choices include QuickBooks, Xero, and FreeAgent.

3. Maintain Accurate Digital Records

Accurate record-keeping is essential. Ensure all invoices, receipts, and bank statements are stored digitally. Many accounting apps integrate directly with HMRC for easy reporting.

4. Schedule Quarterly Updates

Don’t wait until the year-end. Scheduling quarterly updates ensures you stay compliant and reduces the year-end workload.

5. Review End-of-Year Reports

Before submitting the final declaration, review all reports for errors or missing data. Correct discrepancies early to avoid penalties.

Avoiding Common MTD ITSA Pitfalls

Small business owners often face challenges when adapting to digital tax reporting. Common pitfalls include:

  • Delaying registration and missing deadlines
  • Using incompatible software
  • Failing to maintain accurate records
  • Miscalculating allowable expenses

By understanding these challenges and taking proactive steps, your business can stay compliant and stress-free.
