How an Accountant can help you save money on your Self-Assessment Tax Return

How an Accountant can help you save money on your Self-Assessment Tax Return (SATR) 

Filing a self-assessment tax return can be stressful – especially if you’re unsure whether you’re claiming everything you’re entitled to. Many self-employed individuals and business owners end up paying more tax than they need to simply because they don’t know the rules. 

A good accountant can help you reduce your tax bill legally, ensuring you claim every possible deduction while staying fully compliant with HMRC. Here’s how: 

Identifying the allowable expenses…a good accountant should know all!! 

HMRC has strict rules on what expenses you can and can’t claim. An accountant ensures that:  

• You claim all eligible business expenses (including you’ll be unaware of!)  
• Expenses are proportioned correctly for part-business, part-personal use (e.g. home office, vehicle use)  
• You don’t mistakenly claim something that could flag an HMRC investigation 

Example: Many business owners forget they can claim business mileage or a proportion of household costs when working from home! 

Reducing your tax bill with smart Tax Planning 

A good accountant doesn’t just file your return – they plan ahead to help you keep more of your money. This includes:  

• Structuring your income efficiently (e.g. balancing salary vs. dividends for company directors) 
• Make use of tax-free allowances (such as personal allowance and trading allowance)  
• Advising on making pension contributions that reduce taxable income  
• Timing purchases or expenses strategically to maximise deductions 

Example: If you’re close to a higher tax bracket, an accountant might suggest bringing forward expenses to lower your taxable income. 

 Accountants ensuring you don’t miss out on reliefs & allowances 

There are many tax reliefs that self-employed people (or those that meet the criteria for filing a SATR) can claim, but they’re often overlooked.  

An accountant will check if you qualify for:  

• Employment Allowance (if you have staff)  
• Annual Investment Allowance (for equipment & assets)  
• Capital Gains Tax reliefs (if you sell business assets)  
• R&D Tax Credits (if your business involves innovation) 

Example: Many self-employed business owners don’t realise they can claim tax relief on professional development and training courses! 

Avoiding costly mistakes & HMRC penalties 

Getting your tax return wrong could mean paying too much tax or receiving fines from HMRC. An accountant helps by:  

Ensuring figures are accurate and compliant  

Filing on time to avoid late penalties  

Keeping records properly to avoid HMRC investigations 

Example: If HMRC finds an error in your tax return, you could be charged up to 100% of the unpaid tax – even if it was an honest mistake! 

Saving you time & stress 

Filing a self-assessment tax return is time-consuming, especially if you’re not familiar with tax rules. An accountant:  

• Handles all the calculations and paperwork for you  
• Deals with HMRC on your behalf  
• Helps you focus on running your business instead of worrying about tax 

Example: Instead of spending hours digging through receipts, you can simply provide key details and let your accountant handle the rest! 

So, is it worth hiring an Accountant? 

If you’re self-employed or a small business owner, an accountant can help you legally reduce your tax bill, save time, and avoid mistakes. While it might seem like an extra expense, a good accountant will often save you more in tax than they charge in fees!
