Autumn Budget 2025 Predictions: What’s Likely to Change for Limited Companies

• The government is grappling with weak growth and a large deficit.

• No headline increases in income tax, VAT, or employee National Insurance are expected (too politically sensitive).

• Instead, experts predict “stealth taxes,” threshold freezes, and sector-specific levies.

For directors, this means that while the rates you see may not rise, the effective tax burden on your company and personal finances could still increase.

The Budget is expected to include major announcements on business rates, including:

• A possible move from a flat “slab” rate to a “slice” (marginal) system.

• Extensions of small business and “improvement” relief.

• Higher multipliers or surcharges for large commercial properties.

💡 Directors with high-value premises should prepare for potential increases and review rental obligations now.

• The headline rate is expected to stay capped at 25%.

• Adjustments to R&D credits and full expensing rules may be announced.

• Large or cross-border companies may see more compliance scrutiny.

💡 If you’re planning capital investment, model how small changes in reliefs could affect returns.

• Possible alignment of CGT rates more closely with income tax.

• Reductions in reliefs (such as Business Asset Disposal Relief) have been floated.

💡 Directors considering a sale, exit, or asset disposal should assess timings carefully, locking in reliefs before November could preserve value.

Even if rates don’t change, thresholds are likely to remain frozen.

• More company profits may fall into higher tax bands.

• Directors may see more of their dividend or salary income taxed at higher marginal rates.

💡 Revisit your dividend/salary/pension mix to mitigate creeping tax burdens.

• Speculation that NI could be extended to rental income.

• Could affect directors with personal property portfolios or companies holding rental assets.

💡 If rental income is a key stream, factor this risk into cash flow planning.

• Debate continues over standardising pension tax relief at 20%.

• Salary sacrifice arrangements may also be tightened.

💡 Review pension arrangements now to avoid surprises.

• Further reforms to inheritance tax, council tax, or even CGT on primary homes are being debated.

• Large property and wealth holders may face higher liabilities.

💡 Estate and succession planning should be reviewed before November.

• New e-invoicing rules and digital reporting obligations are likely.

• More admin and compliance burdens for SMEs.

💡 Ensure your accounting systems are ready to adapt quickly.

1. Don’t wait until November – model best/worst-case tax scenarios now.
2. Lock in reliefs – complete capital expenditure or disposals where possible.
3. Review remuneration strategies – mitigate frozen thresholds.
4. Prepare for property exposure – rising rates or levies could impact cash flow.
5. Get compliance-ready – avoid being caught out by new digital reporting.
6. Engage your advisers early – forward planning is the best defence.
