HM Revenue & Customs (HMRC) news for 2026 is dominated by the mandatory rollout of Making Tax Digital (MTD) for Income Tax starting April 6, 2026, alongside significant increases to dividend tax rates and reforms to Inheritance Tax reliefs. Taxpayers with a qualifying income over £50,000 must now transition from annual Self Assessment to quarterly digital reporting. Additionally, the dividend basic rate rises to 10.75% and the higher rate to 35.75%, while the long-standing freeze on personal allowances continues to impact take-home pay through fiscal drag.
This comprehensive guide explores the structural shifts within the UK tax system this year, including the new £2.5 million cap on Agricultural and Business Property Reliefs and the transition to the GOV.UK One Login system for all digital services. Readers will gain a deep understanding of compliance deadlines, new corporate tax nuances, and the practical steps required to navigate HMRC’s modernized digital landscape.
Making Tax Digital 2026 Rollout
From April 6, 2026, sole traders and landlords with a combined gross income exceeding £50,000 must use functional compatible software to maintain digital records. This shift replaces the traditional annual Self Assessment return with a requirement for four quarterly updates followed by a final declaration. HMRC has confirmed that paper records will no longer be acceptable for these taxpayers, aiming to reduce manual errors and provide a real-time view of tax liabilities.
The transition represents the most significant change to the UK tax administration in over three decades. Taxpayers must ensure their chosen software can communicate directly with HMRC’s APIs to submit summary data of income and expenses every three months. While the process increases the frequency of reporting, the “Final Declaration” remains due by January 31 following the end of the tax year to reconcile all income sources.
Dividend Tax Rate Increases
The tax rates for dividend income are increasing by two percentage points across the basic and higher rate bands starting in the 2026/27 tax year. Specifically, the basic rate moves from 8.75% to 10.75%, while the higher rate increases from 33.75% to 35.75%. The additional rate for those earning over the top threshold remains unchanged at 39.35%, maintaining a high tax ceiling for the UK’s top earners.
These adjustments specifically target investors and owner-directors who utilize dividends as a core component of their remuneration strategy. With the dividend allowance remaining at a low threshold of £500, a larger portion of investment income is now subject to these higher rates. Financial planners suggest that these changes may necessitate a review of profit extraction methods for small limited companies to ensure tax efficiency.
Inheritance Tax Relief Caps
New restrictions on Agricultural Property Relief (APR) and Business Property Relief (BPR) come into effect on April 6, 2026, introducing a combined £2.5 million cap on 100% relief. Assets exceeding this cumulative limit will only receive 50% relief, effectively resulting in a 20% Inheritance Tax rate on the excess. This change marks a departure from previously unlimited reliefs that allowed large estates and working farms to pass between generations tax-free.
The policy is designed to ensure that the wealthiest estates contribute more to the exchequer while protecting smaller family-owned farms and businesses. HMRC has indicated that the £2.5 million allowance is not transferable between spouses in the same way the Nil Rate Band is, meaning individual planning is critical. Many estate owners are now looking at lifetime gifting strategies to manage potential future liabilities under these new constraints.
Corporation Tax Marginal Relief
UK limited companies with profits between £50,000 and £250,000 must navigate the complex “marginal relief” calculation to determine their effective tax rate in 2026. While the small profits rate remains at 19% and the main rate at 25%, the sliding scale between these figures can result in an effective marginal rate of 26.5% on profits within the bridge. HMRC utilizes a specific fraction to calculate this relief, which must be adjusted if a company has “associated companies” under common control.
The number of associated companies is a critical factor, as it proportionately reduces the £50,000 and £250,000 thresholds. For example, if two companies are associated, the 19% rate only applies to profits up to £25,000 each. Businesses are urged to review their group structures annually, as failing to account for an associated company can lead to significant underpayment penalties and interest charges.
Capital Gains Tax Adjustments
The Capital Gains Tax (CGT) rate for disposals qualifying for Business Asset Disposal Relief (BADR) or Investors’ Relief increases to 18% starting April 6, 2026. This is an increase from the 14% rate applicable in the previous tax year, reducing the tax advantage for entrepreneurs selling their businesses. The annual exempt amount for individuals remains frozen at £3,000, meaning more modest gains are being captured by the tax net.
Standard CGT rates for other assets remain at 18% for basic rate taxpayers and 24% for higher rate taxpayers, excluding residential property which follows separate rules. Investors should note that the timing of a sale is now paramount; transactions completed before the April deadline could save significant sums in tax. HMRC continues to prioritize compliance in this area, utilizing data-matching technology to identify undeclared gains from share platforms and property sales.
National Insurance Contribution Updates
Voluntary Class 2 and Class 3 National Insurance contributions (NICs) are seeing rate increases from April 2026 to help individuals protect their State Pension eligibility. The weekly rate for Class 2 NICs, applicable to the self-employed with low profits, rises to £3.65, while the voluntary Class 3 rate increases to £18.40 per week. A major policy shift also means that voluntary Class 2 contributions can no longer be used to cover periods of time spent working abroad.
These updates are particularly relevant for those with gaps in their contribution records or those approaching retirement age. Individuals living overseas may still be eligible to make Class 3 contributions, though the qualifying criteria have been tightened to ensure the system’s sustainability. HMRC’s digital “Check your State Pension” service remains the primary tool for taxpayers to identify whether making these voluntary payments is a cost-effective move.
GOV.UK One Login Migration
HMRC has officially begun migrating all individual and business taxpayers to the new GOV.UK One Login system for accessing digital tax accounts. This centralized identity verification service replaces the older Government Gateway and verify systems, providing a single set of credentials for all government interactions. New users signing up for HMRC services in 2026 are automatically enrolled in the One Login system, which requires high-strength photo ID verification via a smartphone app.
The migration is part of a broader “Digital First” strategy aimed at making 90% of customer interactions automated by 2030. Existing taxpayers will be invited to migrate in phases throughout the year, with the goal of reducing the administrative burden of managing multiple login details. While the transition enhances security, users are encouraged to set up their accounts well ahead of tax deadlines to avoid verification delays during peak periods.
Business Rates Revaluation 2026
A new business rates revaluation takes effect across England and Wales on April 1, 2026, reflecting property market values as of the 2024 antecedent valuation date. To mitigate the impact of sudden bill increases, HMRC and the Valuation Office Agency (VOA) have introduced a transitional relief scheme that caps the maximum year-on-year rise. Furthermore, eligible pubs and live music venues in England will receive a specific 15% discount on their bills for the 2026/27 period.
Small businesses with rateable values below £500,000 will benefit from permanently lower multipliers compared to larger industrial or retail properties. For the first time, the VOA has made “comparable property” data available online, allowing business owners to see how their valuation compares to similar buildings in their locality. This transparency is intended to reduce the volume of formal appeals by providing clearer evidence for the assigned rateable values.
Compliance and the “Tax Gap”
HMRC has been allocated funding to recruit 5,500 additional compliance caseworkers by 2030, with over 1,500 already active in 2026 to target the “tax gap.” The tax gap—the difference between tax owed and tax collected—is a primary focus for the government, with a target of recovering £50.4 billion in compliance yield this year. New “Guidelines for Compliance” (GfC) have been published to help businesses understand HMRC’s view on complex areas such as R&D tax credits and transfer pricing.
The department is increasingly using AI-driven risk models to connect disparate datasets, including international travel data and bank interest reports. This allows for “nudge” letters to be sent to taxpayers whose declared income does not align with their lifestyle or external data. Enhanced rewards for informants providing information on high-value tax evasion also signal a more aggressive stance toward sophisticated tax avoidance schemes.
Child Benefit Process Reforms
HMRC has apologized for past delays and has reformed its Child Benefit compliance checks to prevent the immediate suspension of payments during enquiries. Starting in early 2026, claimants under investigation will be given at least one month’s notice before any payments are paused, allowing time for evidence to be submitted. This change follows criticism regarding the impact of sudden payment cessations on low-income families’ ability to manage living costs.
The department continues to use international travel data to verify residency status, as unreported moves abroad remain a leading cause of benefit error. Parents are reminded that they must report any changes in circumstances, such as a child leaving education or a change in household income, via the HMRC app to avoid overpayment charges. The High Income Child Benefit Charge (HICBC) remains a key area of focus, with automated checks identifying those who exceed the income threshold but fail to register for Self Assessment.

Frequently Asked Questions
Who must join Making Tax Digital in April 2026?
Any sole trader or landlord with a combined annual gross income from self-employment and property exceeding £50,000 is legally required to join. This threshold is based on turnover (total income before expenses) rather than net profit.
What are the new dividend tax rates for 2026/27?
The basic rate for dividend tax is 10.75% and the higher rate is 35.75%. The additional rate remains at 39.35%, and all taxpayers still receive a £500 tax-free dividend allowance.
How does the £2.5 million Inheritance Tax cap work?
From April 2026, 100% relief on agricultural and business assets is capped at a combined total of £2.5 million. Any value above this threshold receives 50% relief, resulting in an effective tax rate of 20% on the excess.
Can I still file a paper tax return in 2026?
Paper returns are only accepted for those who do not meet the Making Tax Digital criteria or have a specific digital exemption. The deadline for paper returns is significantly earlier—October 31—compared to the January 31 online deadline.
Is the Personal Allowance changing in 2026?
No, the Personal Allowance remains frozen at £12,570 for the 2026/27 tax year. This freeze is expected to continue until 2031, which may lead to “fiscal drag” as inflation pushes more earners into higher tax brackets.
What is the GOV.UK One Login?
It is a new, secure way to sign in to government services using a single email and password. It replaces the old Government Gateway and requires a one-time identity verification process using a photo ID.
Are there any new reliefs for small businesses?
Yes, eligible pubs and live music venues in England will receive a 15% discount on their business rates for 2026/27. Additionally, many small properties with rateable values below £500,000 will benefit from lower rate multipliers.
What happens if I miss a quarterly MTD update?
HMRC uses a points-based penalty system; each late submission earns one point. Once a taxpayer reaches a threshold of four points, a £200 financial penalty is issued for that and every subsequent late submission.
How much does MTD-compatible software cost?
Costs vary widely, from free basic versions for very small businesses to £50+ per month for comprehensive accounting suites. Bridging software is a cheaper alternative for those who prefer to keep records in spreadsheets.
Are Scottish tax rates different in 2026?
Yes, the Scottish Government sets its own Income Tax bands for earned income. While rates remain largely stable for 2026, there are minor adjustments to the basic and intermediate rate thresholds to support lower earners.
Final Thoughts
As the 2026 tax year approaches, the landscape of UK taxation is undergoing its most significant digital and legislative transformation in decades. From the mandatory integration of Making Tax Digital for high-earning individuals to the strategic hikes in dividend and capital gains taxes, the emphasis is clearly shifting toward increased compliance and higher yields from private wealth. Navigating these changes requires not only an understanding of the new rates but also a commitment to the new digital infrastructure, such as the GOV.UK One Login and compatible accounting software. By preparing early and reviewing estate plans in light of the new £2.5 million Inheritance Tax caps, taxpayers can better protect their assets and ensure they remain fully compliant with HMRC’s evolving standards.
