And with recent news from HMRC revealing that they’ll now be able to recover funds directly from bank accounts, here’s everything you need to know.

Keep reading to understand when, why, and how HMRC might look into your financial records. And what you can do to make sure you’re doing everything by the book.

Do HMRC check bank accounts?

HMRC can get relevant information from taxpayers to check they’re paying the right amount of income tax, capital gains tax, corporation tax and VAT.

This information is sometimes held by third parties, and if HMRC wants to see it, they can issue a Financial Institution Notice (FIN) to your bank.

Financial institution Notices are also sometimes known as third party notices.

What is a Financial Institution Notice? 

Since 2021, Financial Institution Notices (FINs) have allowed HMRC to access information from financial institutions about taxpayers. FINs allow HMRC to go directly to your bank, for example, and request information about your finances. 

And they can do this without your permission. Before FINs were introduced, HMRC had to ask for permission from you or a judge to access this information – but that’s no longer the case.

If HMRC believes it’s a ‘reasonable request’ as a part of an investigation, they can use a FIN to request your: 

• financial statements
• loan repayments 
• investment information 
• account ownership information

When would HMRC use a Financial Institution Notice?

FINs are tools for tax investigations. They’re typically used if HMRC believes someone is evading tax, but they’ll sometimes be used in cases of bankruptcy and debt collection too. 

There are a few reasons why HMRC might want to investigate your financial information: 

• inconsistencies in your Self Assessment – if the figures you submit to HMRC don’t match your industry, lifestyle, or previous returns they may investigate further
• whistleblower – you can be reported by if someone believes you’re evading tax 
• random checks – HMRC will occasionally do random checks on taxpayers as a part of its audits 

Certain industries are more likely to be investigated, such as retail businesses with high cash turnover, freelancers, hospitality businesses, and construction and trades businesses.

HMRC investigations – make sure you’re following regulation

Because HMRC can randomly check your business’s financial records, it’s important to keep detailed records. Good financial habits like accurate bookkeeping and having clear records of your company’s expenses will be crucial if you need to provide evidence to HMRC. 

Here are a few tips to try and avoid mistakes that could lead to an HMRC investigation: 

• keep detailed records – accurate records of your business’s income and expenses will help avoid any discrepancies in your tax return 
• file on time – sometimes a late filing is enough for HMRC to take a look at your records 
• be honest with expenses – don’t stretch the limit of allowable expenses and only claim for valid reasons

Why sole traders should separate their accounts 

Because there’s no legal distinction between you and your business as a sole trader, you’ll need to pay particular attention to your tax returns. 

If you end up being investigated by HMRC, your personal assets could be at risk if you haven’t kept accurate records to demonstrate your business income and expenses.

Plus if HMRC notices discrepancies in your accounting, you could be fined for not following regulations.  

HMRC bank account savings tax warning

New rules will soon make it easier for HMRC to collect tax on savings directly from people’s bank accounts.

From April 2027, savings providers will be asked to provide new and existing customers’ National Insurance numbers to HMRC.

This is to allow HMRC to take action against savers who have gone over their personal savings allowance (the amount you can save each year before owing tax on your savings).  It’s £1,000 for basic rate taxpayers and £500 for higher rate taxpayers.
