After months of leaks, speculation and slowing transaction activity, the Chancellor of the Exchequer, Rachel Reeves, has now outlined a raft of tax increases which will impact the Private Rented Sector.
The headline announcement is the introduction of a new mansion tax, applying to properties worth more than £2 million from 2028. While only a small proportion of rental properties fall into this category, the measure underscores a broader shift towards higher taxation of wealth and property assets. A nationwide revaluation process will be required before the surcharge takes effect, which may cause some interim uncertainty for owners of high-value homes, including those held as investment properties or second homes.
For most landlords, however, the more significant changes come from the broader tax package. The Government has confirmed a freeze on income tax and National Insurance thresholds until 2031. Although the thresholds themselves are unchanged, the effect over time—especially in an inflationary environment—is that more landlords will drift into higher tax bands. This fiscal drag increases overall tax liabilities without altering headline rates and reduces net income on rental properties.
Alongside the freeze, the Budget introduces an increase of two percentage points on the taxation of property income, savings income and dividends. For landlords operating through a limited company and paying themselves via dividends, this represents a clear reduction in net returns. The removal of some salary-sacrifice pension advantages beyond £2,000 adds another layer of complexity for those using pension planning as part of their long-term investment strategy. Corporate landlords also face changes to the writing-down allowance, reducing the tax efficiency of maintaining or improving portfolios through company structures.
NRLA say it will ‘clobber tenants’
It is within this context that the National Residential Landlords Association (NRLA) issued one of the strongest reactions of the day. Responding to the OBR’s confirmation that the increase in property-income tax will push up rents, NRLA Chief Executive Ben Beadle said:
“Despite claims of tackling cost of living pressures, the Government is pursuing a policy that the Office for Budget Responsibility has made clear will drive up rents.
“Almost one million new homes to rent are needed by 2031. But this Budget will clobber tenants with higher costs while doing nothing to improve access to the homes people need.”
This stark assessment captures the central tension in today’s announcements. While demand for rental homes continues to rise, the Budget introduces tax measures that risk reducing landlord participation in the sector just when supply is most needed. With returns tightening and regulatory pressure increasing, some landlords may feel prompted to sell, consolidate, or reconsider expansion plans. That, in turn, could exacerbate shortages in many regions and put further upward pressure on rents.
Other parts of the Budget also affect operating costs. A mileage-based charge for electric vehicles from 2028 may impact landlords or property managers who rely on EVs for inspections, maintenance and travel. The freeze on fuel duty, extended by five months, offers only temporary relief before staged increases begin in 2026. At the same time, ongoing requirements relating to energy efficiency, licensing, and the phased introduction of the Renters’ Rights Act continue to add both administrative and financial obligations.
Despite the tough tax environment, rental demand remains strong. High house prices, limited first-time-buyer support and elevated mortgage rates mean many households will remain in the private rented sector for longer. This creates opportunity for professional landlords—but only if they can maintain profitability and navigate the rising cost base.
For landlords, today’s Budget underlines the importance of strategic planning. Reviewing mortgage arrangements, assessing the structure of property holdings, forecasting future tax liabilities, and understanding local rental demand will be essential steps in protecting long-term returns.
This Budget provides certainty in some areas, but also raises important questions about the sustainability of rental supply. Landlords who stay informed, plan ahead and respond proactively to these shifts will be best placed to succeed.
