5 Best Kept Secrets to Save Money on Your
Self Assessment Tax Returns

Saving money on your Self-Assessment Tax return requires a strategic approach. Here are five best-kept secrets to help you minimise your Tax liability:


Utilise All Allowable Deductions


Many Taxpayers miss out on allowable deductions that can significantly reduce their Taxable income. Always check for less obvious deductions such as home office expenses, professional subscriptions, and business mileage. Keeping detailed records throughout the year to support these claims is crucial. Ensure you keep receipts, invoices, and any other documentation that validates your expenses.


Claim Tax Relief for Charitable Donations


If you're making donations to charity, utilise Gift Aid or similar schemes. Donations made through Gift Aid allow charities to claim extra money from the government, increasing the value of your donations and reducing your Taxable income. This is a great way to support causes you care about while also benefiting your Tax situation.


Maximise ISA Investments


Individual Savings Accounts (ISAs) offer a Tax-free way to save. You don’t pay any Tax on the interest or gains from an ISA, making them an excellent way to shield income from Tax. By maximising your ISA contributions, you can secure a sizeable amount of your savings and investments from Taxes. This is especially beneficial if you are saving for long-term goals.


Capital Gains Tax Allowances


Take full advantage of your annual Capital Gains Tax (CGT) allowance, which is the amount of profit you can make from selling assets (like shares or property) before you have to pay Tax on it. Planning your sales across Tax years can help manage and minimise CGT liabilities. If you're considering selling significant assets, spreading the sales over multiple years can reduce your overall Tax bill.


Use Marriage Allowance


If you’re married or in a civil partnership and one of you earns less than the personal allowance (the amount of income you don’t have to pay Tax on), you might be eligible for Marriage Allowance. This allows the lower earner to transfer up to 10% of their personal allowance to their higher-earning partner, reducing their Tax bill. This can be a simple yet effective way to optimise your household’s Tax position.


Bonus Tip: Stay Informed and Plan Ahead


Tax laws change frequently, and staying informed is crucial. Consider consulting with a Tax professional like those at Ultra Tax Ltd to plan your Taxes effectively throughout the year. Proper planning can prevent rushed decisions and maximise your savings when it's time to file your Self-Assessment Tax return.

Understanding Self-Assessment Tax Returns

The Importance of Early Filing

Filing your tax return early has significant advantages. It helps avoid last-minute stress, reduces the risk of penalties for late submission, and allows better financial planning. Early filing ensures you know your tax liability well in advance, giving you more time to arrange payment if necessary.

What if I am owed Tax Back?

If you discover that you're owed money from overpaid taxes, we at Ultra Tax Ltd will make it straightforward to claim your tax rebate.


Simply visit our tax rebates page and fill out the provided form to get started.


A tax rebate often occurs when you have paid more tax than you are liable for during the tax year. This can happen due to various reasons such as not utilising all your tax-free allowance, overestimation of taxable income, or incorrect tax code applications.

A tax rebate or tax refund provides a means for you to reclaim any tax that you have overpaid. It's essentially the government returning money that rightfully belongs to you, which may have been over-collected through payroll in the case of employment under PAYE (Pay As You Earn) or through direct payments for self-assessed taxes.

For many, this can represent a significant amount of money that could positively impact personal finances.

At Ultra Tax Ltd, we specialise in identifying these overpayments and assisting our clients in reclaiming what is rightfully theirs.

By filling out our simple online form on our Tax Rebates page, you provide us with the initial information we need to assess your situation and calculate the potential rebate.

Our process is designed to be transparent, efficient, and user-friendly, ensuring that you understand every step and feel confident that you are getting the maximum rebate due.

Whether you’re an employee who’s been on the wrong tax code, a sole trader who has made advance payments exceeding their tax liability, or even a retiree who has not fully utilised their personal allowance, our team is here to help.


After submitting your information through our form, our tax professionals will review your case, handle all necessary calculations, and get started with your tax rebate from HMRC.

Don’t let the complexities of tax rebates deter you from claiming what you are owed. Ultra Tax Ltd is committed to providing expert guidance and support throughout the entire process, helping you recover any overpaid taxes efficiently.

Visit our tax rebates page today, fill out the form, and take the first step towards securing your refund with the help of our knowledgeable team.

What is Self-Assessment?

Self-Assessment is a method used by HM Revenue and Customs (HMRC) to collect Income Tax. It's a way for individuals and businesses to report their income and calculate their Tax liability. While most income Tax is deducted automatically from wages, pensions, and savings, those with other income sources must file a Tax return.


Self-Assessment applies to a wide range of individuals, including the self-employed, company directors, and landlords. Understanding the requirements and deadlines associated with Self-Assessment is crucial to avoid penalties and ensure compliance.

Key Deadlines for Self-Assessment

5 October: Register for Self-Assessment if you’re self-employed or a new partner in a business partnership.

31 October: Submit your paper Tax return.

31 January: Submit your online Tax return and pay the Tax you owe.


Missing these deadlines can result in penalties and interest charges. Therefore, it's crucial to mark these dates in your calendar and ensure all necessary information and documents are ready well in advance.


Penalties for Late Submission


Failing to file your Tax return on time can lead to penalties:


1 day late: £100 fine.

3 months late: Additional daily penalties of £10 per day, up to a maximum of £900.

6 months late: Further penalties of 5% of the Tax due or £300 (whichever is greater).

12 months late: Additional penalties, depending on your circumstances, can be as much as 100% of the Tax due.


Understanding these penalties underscores the importance of timely filing. Proactive Tax planning and organisation can help avoid these costly penalties.
