VAT Explained

When your business starts to grow, reaching the VAT registration threshold is a major milestone—but it’s also one that brings a whole new set of rules and responsibilities.

At Your Accounting Club, we help you navigate the "VAT maze," from spotting the exact moment you need to register to ensuring you’re on the most tax-efficient scheme for your cash

The VAT Registration Thresholds

The most important number to remember for the 2025/26 tax year is £90,000. However, it’s not just a case of checking your year-end accounts. There are two distinct tests you must run:

The 12-Month Rolling Test: Every month, you must look back at your total taxable turnover for the previous 12 months. If that total hits or exceeds £90,000, you must register.
The 30-Day Forward Look: If you expect your turnover to exceed £90,000 in the next 30 days alone (for example, if you just landed a huge contract), you must register immediately.

Note: You have 30 days from the end of the month you crossed the threshold to notify HMRC. If you’re late, they can issue penalties based on how much VAT was "lost" during the delay.

Understanding Input vs. Output VAT

Once you are registered, you effectively become a tax collector for HMRC.

Output VAT: This is the VAT you add to your sales invoices. You collect this from your customers and hold it for HMRC.
Input VAT: This is the VAT you pay on your business purchases (equipment, stock, software, etc.). On your VAT return, you subtract your Input VAT from your Output VAT. If you’ve collected more than you’ve paid, you pay the difference to HMRC. If you’ve paid more than you’ve collected, you get a refund.

VAT Rates in the UK

Not every sale is taxed the same way. The three main rates are:

Standard Rate (20%): Applies to most goods and services.
Reduced Rate (5%): Applies to things like home energy or children's car seats.
Zero Rate (0%): Applies to most food, books, and children’s clothing. Even though the rate is 0%, these sales still count toward your £90,000 threshold.

Choosing the Right VAT Scheme

By default, you’ll use Standard Accounting, but for many small businesses, one of these alternatives works better:

Cash Accounting: You only account for VAT when money actually hits your bank account, rather than when you send the invoice. This is a lifesaver for cash flow if your clients are slow payers.
Flat Rate Scheme: Designed for small businesses (turnover under £150k), you pay a fixed percentage of your turnover to HMRC. You don't reclaim VAT on most purchases, but the admin is much simpler.
Annual Accounting: Instead of four quarterly returns, you file one return a year and make fixed monthly or quarterly payments.

Backdated VAT Reclaims: The "Startup Bonus"

One of the biggest perks of registering for VAT is the ability to reclaim tax on things you bought before you were registered.

Goods: You can go back 4 years for items you still have in stock or assets (like laptops or machinery) still in use by the business.
Services: You can go back 6 months for services (like accountancy or legal fees) that related to the business. To claim these, you must have the original VAT invoices. This "pre-registration" claim is made on your very first VAT return and can often result in a significant initial refund.

Compliance and MTD

Under Making Tax Digital (MTD), you are legally required to keep digital records and submit your returns using functional compatible software (like Xero or QuickBooks). Gone are the days of manual typing into the HMRC portal; your software must "talk" directly to HMRC.
