HMRC Simplified: The Complete Guide to VAT for UK Businesses
VAT (Value Added Tax) is one of the most important taxes in the UK — yet it’s often misunderstood. Unlike corporation tax, VAT isn’t based on your profit. It’s a tax on sales, collected by businesses on behalf of HMRC.
If you don’t manage VAT correctly, you risk late registration, penalties, and unexpected tax bills that can devastate your cashflow. Here’s everything business owners need to know.
What is VAT?
VAT is a consumption tax applied to most goods and services in the UK. Businesses add VAT to their sales (“output VAT”) and can usually reclaim VAT paid on purchases (“input VAT”).
The main rates are:
20% standard rate — applies to most goods and services.
5% reduced rate — applies to specific items such as home energy.
0% zero rate — covers items such as most food, books, and children’s clothes.
👉 Example: Invoice £1,000 plus VAT at 20%. The client pays £1,200. That £200 goes to HMRC — it isn’t part of your profit.
Who Needs to Register for VAT?
You must register if your taxable turnover exceeds £90,000 in a rolling 12-month period. HMRC looks at your revenue month by month — not by calendar or tax year.
Some businesses also register voluntarily to reclaim VAT on expenses or to appear more established when dealing with VAT-registered customers.
Miss registration and HMRC will:
Demand VAT from the date you should have registered.
Charge interest.
Apply late registration penalties.
Charging VAT to Customers
Once registered, VAT must be added to invoices at the correct rate.
Forgetting to charge VAT doesn’t remove the liability. HMRC still expects payment — meaning you absorb the cost yourself.
👉 Example: Quote £1,000 without VAT when you should have charged £1,200. You’ll only keep about £833.33 after HMRC takes its share.
Reclaiming VAT on Expenses
VAT-registered businesses can reclaim VAT on most business-related expenses, including:
Stock and raw materials
Equipment, tools, and machinery
Professional services
But some expenses are blocked, such as client entertainment. For mixed-use items (like vehicles), only a portion may be reclaimed.
Receipts and digital records are essential — HMRC won’t accept estimates.
VAT Schemes Available
Different VAT schemes can ease administration and improve cashflow:
Standard VAT Accounting — record VAT on invoices raised and received.
Cash Accounting Scheme — only pay VAT when customers pay you.
Flat Rate Scheme — pay a set percentage of turnover instead of tracking all transactions.
Annual Accounting Scheme — submit one return per year, with instalments in between.
Choosing the right scheme depends on your turnover, industry, and cashflow.
Filing VAT Returns
VAT returns are typically submitted every quarter under Making Tax Digital (MTD) rules. Returns must be filed through approved software.
Late or missed returns can result in:
Fixed penalties
Interest on unpaid VAT
Compliance checks
