Autumn Budget Shock: Why a 2p Income Tax Increase Would Disadvantage the Self-Employed

As the government prepares for the upcoming Autumn Budget 2025, speculation is growing around possible tax adjustments that could reshape the financial landscape for millions of self-employed individuals. Reports suggest that Chancellor Rachel Reeves is considering a plan to raise Income Tax by 2p while reducing employees’ National Insurance by the same amount.

While the move is being framed as a way to boost revenue without directly impacting employed workers, the ripple effects for the self-employed could be significant. Those who run their own businesses or operate as sole traders might find themselves paying more tax overall, without receiving any of the offsetting benefits designed for employees.

What the Proposed 2p Tax Rise Means

The proposal under discussion is based on ideas from a Resolution Foundation report, which suggests taking 2p off National Insurance contributions for employees and adding it to Income Tax. According to early estimates, this adjustment could generate around £6 billion in additional revenue for the Treasury. The approach would allow the government to raise funds while technically maintaining its commitment not to increase taxes for “working people.”

However, because self-employed individuals pay a different form of National Insurance at lower rates and will not benefit from the employee reduction, they would still face the Income Tax increase. The result is an uneven impact across income types.

The Financial Impact on the Self-Employed

For self-employed people, the numbers tell a clear story. Someone earning £20,000 a year could be around £149 worse off annually, while those earning £30,000 may lose about £349. Higher earners making £50,000 could see their take-home income reduced by roughly £749 per year.

This difference arises because the self-employed pay Class 4 National Insurance contributions, which currently stand at 6% on profits between £12,570 and £50,270 and 2% on profits above that threshold. Since the proposed National Insurance cut would only apply to employees, the self-employed would shoulder the Income Tax increase without receiving any corresponding relief.

This means that freelancers, contractors and small business owners, who already have irregular earnings and fewer safety nets, could experience tighter margins and additional pressure on their personal finances.

Other Groups Are Also Affected

The potential 2p Income Tax rise wouldn’t only affect the self-employed. Pensioners, landlords and individuals receiving income from savings could also see higher tax bills. For instance, someone drawing a pension income of £35,000 would pay an additional £449 per year under the proposed rate increase.

Savings interest outside of Individual Savings Accounts (ISAs) and rental income could also face higher deductions, especially for those whose earnings push them into higher tax brackets. These groups are not covered by the proposed National Insurance reduction and would therefore feel the full weight of the Income Tax rise.

Possible Dividend Tax Increases

In addition to Income Tax adjustments, there is growing talk of changes to dividend taxation. This would be particularly concerning for business owners who take part of their income as dividends. While the higher and additional Dividend Tax rates are already close to Income Tax rates, the basic rate remains lower at 8.75%.

If the government decides to align these rates more closely, individuals who rely on dividend income, including self-employed company directors and investors with shares outside ISAs or pensions, could face another hit. With the annual dividend allowance now reduced to £500, the room to minimise such taxes has already narrowed significantly.

The Current Financial Strain on the Self-Employed

Self-employed workers are already in a challenging position compared to their employed counterparts. Research indicates they typically earn less, save less and have less financial stability month-to-month. On average, households led by self-employed individuals have about £89 left over at the end of each month, compared to £244 among employed households.

Irregular income patterns can also make it difficult to build savings or contribute regularly to pensions. The average self-employed worker saves just 2.3% of their income, while employees manage to put away around 5.6%. A new tax rise could therefore deepen the divide between these groups and make financial planning even harder for those running their own ventures.

How the Self-Employed Can Prepare for this Autumn Budget Shock

Although these changes are not yet confirmed, self-employed individuals can take proactive steps to reduce their exposure and plan ahead. One practical measure is to review how and when income is received. For instance, bringing forward dividend payments if rules are likely to change. This can help secure a lower tax rate before any increases take effect.

Another effective strategy is contributing to pensions or Self-Invested Personal Pensions (SIPPs). These contributions reduce taxable income while offering valuable long-term benefits. ISAs also remain an important tool, allowing savers to shield interest and investment income from tax altogether. Moving investments into ISAs or SIPPs, sometimes referred to as the Bed & ISA or Bed & SIPP process, can help lock in tax-efficient growth over time.

For those who qualify, a Lifetime ISA (LISA) can provide additional support. The 25% government bonus on contributions up to £4,000 effectively offers tax relief similar to pensions, with the added benefit of flexibility. Though withdrawals before age 60 attract a penalty, the LISA remains a useful tool for long-term savings and homeownership goals.

Some financial experts have suggested the government could make LISAs more accessible by extending the eligibility age beyond 40, potentially benefiting over a million self-employed households who currently fall outside the limit.

Conclusion

If the government moves forward with a 2p rise in Income Tax while reducing National Insurance for employees, the self-employed could find themselves disproportionately affected. Those who manage fluctuating incomes, limited safety nets and fewer employment benefits already face unique financial challenges, and the proposed changes could add another layer of strain.

However, there are still ways to prepare. By using tax-efficient investment vehicles like ISAs, pensions and LISAs, and by staying alert to upcoming Autumn Budget announcements, self-employed individuals can adapt their strategies and minimise the impact of future tax rises. The coming months will reveal whether these proposals remain speculative or become part of the UK’s new fiscal reality.
