Goodbye Government Gateway? Filing Your Tax Return in the MTD Era
- Jul 16
- 6 min read
For many years, the Government Gateway has been the digital front door for small business owners and landlords across the UK. Whether you were filing a Self Assessment return on a Sunday evening or checking your VAT status, that familiar green-and-white login screen was a staple of the business calendar.
However, the landscape of UK tax is shifting. With the rollout of Making Tax Digital (MTD), the way we interact with HMRC is moving away from manual web forms and toward integrated software. This has left many asking: "Is it finally goodbye to the Government Gateway?"
In this article, we’ll explore the future of the Gateway, what the 2026/27 MTD for Income Tax changes mean for you, and how the new "GOV.UK One Login" fits into the puzzle.
The Familiarity of the Government Gateway
The Government Gateway was established over two decades ago to provide a centralized point for citizens to access government services. For the self-employed, it became synonymous with the annual tax return. You would log in, type your figures into the boxes provided by HMRC, click "submit," and receive your confirmation.
It was a manual process, but it was a familiar one. However, as the world has moved toward real-time data and automation, the traditional Gateway filing method has begun to show its age. HMRC’s long-term goal is to move away from "periodic" filing (once a year) to "continuous" digital record-keeping.
What is Making Tax Digital (MTD)?
Making Tax Digital is a government initiative designed to make it easier for individuals and businesses to get their tax right and stay on top of their affairs. Instead of a single annual event, MTD requires businesses to keep digital records and provide quarterly updates to HMRC using MTD-compatible software.

We have already seen this transition for VAT. Since 2022, nearly all VAT-registered businesses have been required to use software to file their returns. The option to simply "type in the numbers" on a Government Gateway web page was removed for the vast majority of VAT filers.

The 2026 and 2027 Deadlines: MTD for Income Tax
The next big phase is MTD for Income Tax Self Assessment (ITSA). This change will affect millions of self-employed individuals and landlords.
From April 2026: Self-employed individuals and landlords with an income of more than £50,000 will be required to follow MTD rules.
From April 2027: Those with an income over £30,000 will be brought into the fold.
For these taxpayers, the "old" way of filing a Self Assessment return via the Government Gateway web forms will effectively disappear.
No More "Manual" Filing
HMRC has stated that for those within the scope of MTD for Income Tax, they will not provide an online filing service on the GOV.UK website. Instead, you must use a "full software journey." This means you will need to choose MTD-compatible software to record your income and expenses and to send your quarterly updates and final declarations to HMRC. If you currently work from spreadsheets, this guide on how to integrate Excel with MTD bridging software in 5 minutes is a useful place to start.

If you are currently used to logging into the Gateway to do it yourself, the transition might feel daunting. This is where a dedicated accountant becomes an invaluable partner. They can help you select the right software and ensure your digital records are compliant.
Is the Government Gateway Actually Closing?
It is important to distinguish between filing and logging in. While the ability to file a tax return through a manual form on the Gateway is being phased out for MTD taxpayers, the Government Gateway identity isn’t disappearing overnight: though it is evolving.
The Rise of GOV.UK One Login
Parallel to the MTD changes, the government is rolling out a new system called GOV.UK One Login. The goal is to replace the multiple ways people currently sign in to government services (including the Government Gateway) with a single, secure account.
By 2026 and 2027, many services that currently use the Government Gateway will have migrated to One Login. For example, Companies House has already indicated that its WebFiling service will require the new One Login identity in the near future.
So, while the name "Government Gateway" might eventually fade into the history books, you will still need a digital ID to access your tax records: it will just be a more modern, streamlined version.
What This Means for Landlords
Landlords are often the group most surprised by these changes. Many landlords manage their properties as a side venture and have historically relied on a simple spreadsheet and a manual Gateway submission once a year.
Under MTD for Income Tax, if your property income (combined with any self-employed income) exceeds the £50,000 threshold in 2026, you will need to:
Keep digital records of every rent payment and every repair bill.
Submit a summary of this data to HMRC every three months.
Complete a "Final Declaration" at the end of the tax year via software.
The era of "shoebox accounting" or manual Gateway entries is coming to an end. Landlords should look into specialist tax advice now to ensure they are ready for the digital switchover.
What This Means for SME Owners
For small business owners, the transition might be smoother if you are already using accounting software like Xero, QuickBooks, or Sage for your VAT returns. However, the frequency of reporting is increasing.
The move away from the Government Gateway filing screen means your software must be "MTD-compliant." If you are a limited company accountant or director, you should already be familiar with digital filing, but the integration between your personal tax and business tax is becoming more deeply digitized.
The Benefits of Moving Away from the Gateway
While change can be frustrating, the move toward software-based filing offers several advantages over the old manual Gateway method:
Real-time Accuracy: Software can link directly to your bank account, reducing the risk of manual data entry errors.
Better Financial Visibility: Instead of waiting until January to find out how much tax you owe, software gives you a running estimate of your tax liability throughout the year.
Automation: Tasks that used to take hours: like reconciling receipts: can now be done in minutes using smartphone apps that scan and upload data directly into your accounts.
How to Prepare for the "Post-Gateway" Era
If you aren't yet using software to manage your taxes, now is the time to start. 2026 may seem far away, but setting up your digital records now will save you a massive headache when the deadline arrives.

By moving away from the Gateway and toward MTD-compatible software, you aren't just complying with HMRC; you are gaining better control over your business finances. Don't wait until the 2026 deadline: start your digital journey today and ensure your business is ready for the new era of taxation.
