The clock is ticking! The UK tax deadline is just days away. If you haven’t yet submitted your Self Assessment tax return or finalised your tax planning, now is the time to act.
While October 31st might seem like the finish line, there’s still a lot you can do to make sure your submission is accurate, compliant, and optimised. Whether you’re a UK resident, a dual taxpayer, or an expat managing global income, a few smart moves can make a big difference both for this year and the next.
In this article, Lead Solution Wealth Management explores last-minute UK tax planning strategies you can still apply before the deadline and how to set yourself up for a smoother year ahead.
1. Double-Check Your Tax Return Before Submitting
It may sound obvious, but one of the most common mistakes taxpayers make is rushing through their Self Assessment form. Even small errors such as incorrect income figures or missing documentation can lead to delays, penalties, or unwanted attention from HMRC.
Take a few minutes to review the following:
- Your income sources (employment, self-employment, rental, dividends, etc.)
- Your allowable expenses and deductions
- Any foreign income declarations, especially if you’re an expat or non-resident
If you’re uncertain about what needs to be included, or if your financial situation has changed during the year, now is the perfect time to get professional help. Expert tax consultants like Lead Solution Wealth Management can help identify mistakes that could otherwise cost you money or compliance issues later on.
2. Maximise Your Allowances and Deductions
Even in the final days before the deadline, there are a few last-minute opportunities to make your tax bill more efficient.
Consider whether you’ve made full use of:
- ISA contributions (Individual Savings Accounts) – while you can’t backdate them, contributing within the tax year can reduce taxable income.
- Pension contributions – increasing your contributions before filing can boost your retirement fund and lower your taxable income.
- Charitable donations – Gift Aid allows you to claim tax relief on eligible donations made during the tax year.
- Capital gains tax exemptions – if you’ve sold assets, ensure you’re within your annual CGT allowance and report any gains accurately.
A quick review of your financials with a qualified tax advisor can reveal valuable savings you might have missed.
3. File On Time — Even If It’s Not Perfect Yet
Missing the October 31st paper filing deadline (or January 31st for online submissions) can result in automatic penalties, starting from £100 — even if you owe nothing.
If you’re running short on time:
- Submit your return now, even if it’s not fully optimised.
- You can amend your return later — up to 12 months after the original submission date.
This approach ensures you stay compliant while still allowing room for adjustments. It’s always better to file on time and make corrections later than to miss the deadline altogether.
4. Prepare for Digital Tax Reporting
HMRC’s Making Tax Digital (MTD) initiative continues to evolve, requiring more individuals and businesses to maintain digital records and submit information online.
If you’ve been relying on paper returns or manual bookkeeping, this is your sign to start preparing for the shift. Digital systems not only keep you compliant but also:
- Simplify record-keeping
- Reduce calculation errors
- Make future tax filings faster and easier
At Lead Solution Wealth Management, we help clients transition to digital tax systems efficiently, saving time and preventing last-minute stress when deadlines approach.
5. Don’t Forget About International Income
If you’re a UK expat or have income from foreign sources, ensure that everything is declared correctly under UK tax rules.
The UK has multiple double taxation agreements (DTAs) to prevent you from being taxed twice on the same income. However, you still need to report foreign earnings, investments, or property income properly even if it’s already taxed abroad.
This is particularly important for those affected by US FATCA or other global tax reporting requirements, as international compliance adds another layer of complexity. A professional adviser like Lead Solution Wealth Management can ensure your international obligations align with UK requirements and thus avoid costly errors or HMRC investigations.
6. Use This Deadline as a Planning Opportunity
While the next few days might feel like a rush, this is also a great time to plan ahead for next year’s tax season.
Ask yourself:
- Were you scrambling for receipts and records this year?
- Did you miss out on deductions you didn’t know about?
- Have your personal or business circumstances changed recently?
If so, setting up a year-round tax strategy can make a world of difference. Regular check-ins with a tax professional can help you plan efficiently, stay compliant across jurisdictions, and identify new ways to optimise your tax position.
