## What’s Changing for Individuals & Self-Assessors
Several significant changes relevant to those with complex incomes—dividends, property, savings—or who use Self Assessment are coming into force from **6 April 2026** (tax year 2026-27) and onward.([gov.uk](https://www.gov.uk/government/publications/budget-2025-overview-of-tax-legislation-and-rates-ootlar/budget-2025-overview-of-tax-legislation-and-rates-ootlar?utm_source=openai))
### Key Changes
- **Dividend income tax rates** increase by *2 percentage points*: ordinary rate to **10.75%**, upper rate to **35.75%**. Additional rate remains at **39.35%**.([gov.uk](https://www.gov.uk/government/publications/budget-2025-overview-of-tax-legislation-and-rates-ootlar/budget-2025-overview-of-tax-legislation-and-rates-ootlar?utm_source=openai))
- **Property income rates set separately** from 2027-28: basic rate 22%, higher 42%, additional 47% across England, Wales, and Northern Ireland.([gov.uk](https://www.gov.uk/government/publications/budget-2025-overview-of-tax-legislation-and-rates-ootlar/budget-2025-overview-of-tax-legislation-and-rates-ootlar?utm_source=openai))
- **Savings income rates** will also rise by 2 ppts, moving to 22%, 42%, and 47% from April 2027.([gov.uk](https://www.gov.uk/government/publications/budget-2025-overview-of-tax-legislation-and-rates-ootlar/budget-2025-overview-of-tax-legislation-and-rates-ootlar?utm_source=openai))
- Increased thresholds under various schemes: the Personal Allowance is set at £12,570; basic and higher rate thresholds are also fixed for multiple years.([gov.uk](https://www.gov.uk/government/publications/budget-2025-overview-of-tax-legislation-and-rates-ootlar/budget-2025-overview-of-tax-legislation-and-rates-ootlar?utm_source=openai))
## What This Means in Practice
- Individuals who receive income from **dividends**, **savings interest**, or **rental properties** should run projections now for what their liability might be post-change.
- Self Assessment forms will need to capture more detail about non-employment income. Budget planning should involve estimating effects to avoid surprises at filing time.
## Actionable Compliance Steps
1. **Review your income mix**: see how much you draw from salary vs dividends vs rental vs savings. That affects how much rate increases will hit you.
2. **Use tax bands efficiently**: for instance, dividends benefit from the dividend allowance; salary should be planned around personal allowances.
3. **Consider shifting income timing**: Deferring income or accelerating expenses before the new rates for property or savings might manage tax payable.
4. **Use reliefs and allowances**: charitable gifts, pension contributions, and other deductions may help reduce taxable amounts under higher rates.
5. **Keep documentation well organized**, especially for rental income, expenses, repairs (which reliefs are allowed vs capital improvements) and dividend statements.
## Example Scenario
- **Sophie**, a consultant, tells her accountant she expects £20,000 in dividends, £5,000 interest income, and £7,000 from a rental property. After the changes, her dividend rate goes up, and property income is taxed at higher bands. Sophie could increase deductible expenses (maintenance, allowable travel), perhaps prepay some, to reduce net taxable property income.
- **David**, a high net worth individual, with large savings and investments, should consider moving some interest-bearing assets to tax-efficient wrappers (ISAs, pensions etc.), where possible, especially before savings income rates go up in 2027.
## Keeping on Top of Self Assessment
- HMRC is increasing **in-year PAYE obligations** for those also required to Self Assess (from April 2029) – meaning more tax due via PAYE rather than lump-sum payments.([gov.uk](https://www.gov.uk/government/publications/budget-2025-overview-of-tax-legislation-and-rates-ootlar/budget-2025-overview-of-tax-legislation-and-rates-ootlar?utm_source=openai))
- Penalties for late or incorrect returns remain in force; higher income and diversified income usually mean greater risks of error.
## Final Thoughts
Higher earners, landlords, and those with diverse income portfolios should review their tax plans in light of the new rates and thresholds. Changes to dividends rates, property revenue, and savings may increase tax bills, but careful planning and using reliefs strategically can mitigate the impact.
