A VAT loan is business borrowing that pays your VAT bill on time, so you repay a lender over a few months instead of paying HMRC in one go. This guide helps UK limited company directors compare the cost with HMRC's late payment penalties and Time to Pay, and choose the right option.

Worth knowing: pay HMRC 31 days late and penalties reach 6% of the bill, then a daily penalty of 10% a year kicks in on top of interest at 7.75% a year. On a £20,000 bill paid 45 days late, that's about £1,473. (Source: gov.uk, rates from 9 January 2026.)

What is a VAT loan?

A VAT loan is borrowing you use to pay your VAT bill on time, then repay the lender over a few months. It swaps one lump sum to HMRC for smaller, planned repayments.

It isn't a special kind of product so much as a purpose. Some lenders sell a dedicated 'VAT loan' with a short term. Others, like iwoca, offer a flexible business loan you can use for the VAT bill and repay once your cash catches up. Either way, HMRC gets paid in full and on time, and your company owes the lender instead.

‍

Why would a limited company need a VAT loan?

Usually because the VAT you've charged customers has already gone into running the business, or customers haven't paid yet, by the time the bill is due.

Once your taxable turnover passes £90,000 in any 12 months, you have to register for VAT. From then on you collect VAT on HMRC's behalf and pay it over, usually every three months. The money passes through your account on the way, and that's where the gap opens up.

Common reasons the cash isn't there on the day:

• Customers pay on 30-day terms or longer, but VAT is due on the invoice.
• You've invested in stock or equipment ahead of a busy season.
• Costs for materials or supplies have gone up and squeezed your margin.
• An unexpected cost, like a repair or replacement, landed in the same quarter.
• Sales dipped, but the VAT from a stronger earlier month is still due.

Some sectors feel this more than others because of how and when they get paid:

• Construction and property: large upfront material costs and long payment schedules.
• Retail and ecommerce: seasonal swings and stock bought well before it sells.
• Manufacturing: VAT on equipment and raw materials, and long payment cycles.
• Wholesale: cash tied up in stock and VAT on imported goods.
• Professional services and recruitment: long projects, or paying staff weekly while clients pay monthly.

‍

How does a VAT loan work?

Some lenders pay HMRC directly and others pay the money to you so you can pay HMRC yourself. Terms are usually three months and sometimes up to 12 months.

You apply once you know your VAT figure. If you're approved, the lender either sends the payment straight to HMRC or pays it into your business account so you can pay your VAT bill as normal. Then you repay the lender in instalments, plus interest and any fees.

How much you can borrow depends on the lender and on your business, mainly your turnover and your ability to repay. Dedicated VAT lenders often cap the loan at the size of the bill. A general business loan can cover the VAT bill and a little breathing room, but it's worth borrowing only what you need.

‍

When should you apply for a VAT loan?

Apply once you've filed your return and know the figure, well before the payment deadline of one calendar month and seven days after the end of your VAT period.

1. Close your VAT period and submit your VAT return so you know exactly what you owe.
2. Check your cash flow for the next few months, including when big customer payments are due.
3. Apply for the loan with time to spare. Lenders need time to decide and pay out, and your payment has to reach HMRC by the deadline, even if it falls on a weekend or bank holiday.
4. Pay HMRC, or check the lender has.

Speed varies by lender and by how complete your application is.

Who can get a VAT loan?

Lenders mostly look at your trading history, turnover, credit record and whether you can afford the repayments. Many ask directors for a personal guarantee.

What lenders usually check:

• How long your company has been trading.
• Your turnover and how steady it is.
• Your company's credit history and any existing borrowing.
• Whether the repayments fit alongside your next VAT bill.

What you'll usually need to apply:

• Your latest VAT return, or the figure you owe.
• Recent business bank statements.
• Your company's filed accounts, if you have them.

Most business lenders, iwoca included, ask directors to sign a personal guarantee. It means you'd be personally responsible for the debt if the company couldn't repay, so read what you're signing.

How much does a VAT loan cost?

You pay interest and sometimes fees, so compare the total you'll repay rather than the headline rate. Then set it against what paying HMRC late would cost.

The cost of a VAT loan depends on the amount, the term, the lender and your business. A shorter term, or repaying early, usually means less interest. Watch for arrangement fees and early repayment fees, which can change the real cost.

Here's what the same £20,000 bill costs in four situations:

On price alone, a Flexi-Loan won't win that comparison. What it buys is timing and control: HMRC is paid in full on the deadline, there's nothing to negotiate, and the loan lasts only as long as your cash gap. And because interest is charged only on what you owe, the cost follows the gap: repay a month after the deadline, when your customers pay, and the interest is about £666.

‍

What happens if you can't pay your VAT bill on time?

HMRC charges interest from the first day you're late, then penalties from day 16: 3% at first, another 3% after 30 days and a daily penalty of 10% a year after that.

Late payment interest is the Bank of England base rate plus 4%, charged from the day after the deadline. It's 7.75% a year from 9 January 2026.

If you know you can't pay, act before day 15. Either set up Time to Pay with HMRC or arrange finance, because both stop the penalties from building. Our guide to penalties for paying late covers the rules for other taxes too.

‍

VAT loan or HMRC Time to Pay?

Time to Pay spreads the bill with HMRC and can cut or avoid penalties if you ask by day 15, but interest still runs. A loan pays HMRC in full and moves the debt to a lender.

Neither is always cheaper. Time to Pay can cost less if HMRC agrees and the plan fits your cash flow. A loan gives you certainty that HMRC is paid, which matters if you'd rather not have an open tax debt or HMRC is unlikely to agree. Our comparison of HMRC Time to Pay or a business loan goes into more detail. If you choose HMRC, here's how to set up a VAT payment plan.

The pros and cons of VAT loans

A VAT loan keeps you on the right side of HMRC and protects your cash. But it's still debt, and you'll need to repay it while the next quarter's VAT builds up.

‍

Advantages of a VAT loan

• You pay HMRC on time and avoid late payment penalties and interest.
• The cost is spread over months instead of one lump sum.
• Cash stays free for wages, suppliers and stock.
• With some lenders, the money goes straight to HMRC.

‍

Disadvantages of a VAT loan

• You pay interest and possibly fees, so compare the total repayable.
• Repayments run alongside your next VAT bill, so plan for both.
• You may need to sign a personal guarantee.

‍

How to choose a VAT loan

Compare the total cost, whether the term finishes before your next VAT bill, early repayment fees, any security or guarantees and who the money is paid to.

Before you apply, check:

• Total repayable: the interest and every fee, not just the rate.
• Term: ideally you've repaid before the next quarter's VAT is due.
• Early repayment: whether you can clear it early without fees when customers pay.
• Security: whether the lender wants a charge over property or a personal guarantee.
• Who gets the money: HMRC directly, or your account so you control the payment.
• Flexibility: a fixed VAT loan suits a one-off bill, while a flexible business loan can help if you only want to borrow for as long as you need.
• Speed: whether a decision and payout will arrive before the deadline.

Using a Flexi-Loan for your VAT bill

An iwoca Flexi-Loan pays into your business account, so you pay HMRC as usual. You can borrow from £1,000 to £1m and repay early without fees once customers pay.

We lend to UK limited companies, and there's no minimum trading time. Startups can borrow up to £10,000. How it works for a VAT bill:

• Apply online with your company details and bank statements.
• Borrow what the bill needs. The amount is usually up to about one month's turnover.
• Pay HMRC yourself from your account, so you control when the payment goes.
• Repay early, without fees, when customer invoices come in.
• Spread it for longer if you need to: terms run up to five years.

We don't take a charge over property. Every new Flexi-Loan comes with a personal guarantee.

Guy Walker, founder of recruitment firm Dovetail and Slate, used a Flexi-Loan to bridge VAT, salaries and suppliers over the summer:

"iwoca was different. There were no pushy salespeople. They were clear about the model, the amount, the payment structure, and the interest. I didn't even need to involve my finance team, which never happens with lending."

If it sounds like a fit, you can check your eligibility for a Flexi-Loan in a few minutes.

‍

Are VAT bridging loans the same as VAT loans?

Not quite. A VAT bridging loan covers the VAT on a large purchase, usually commercial property, until you reclaim it from HMRC.

When you buy commercial property that's had VAT charged on it, the VAT can be a very large sum due at completion. Buyers use a bridging loan to cover it for the few weeks or months until HMRC repays the VAT. A standard VAT loan is different: it spreads your own VAT bill to HMRC.

‍

Do you pay VAT on a loan?

No. Lending money and the interest on it are exempt from VAT, so there's no VAT on your loan or your repayments.

HMRC treats lending as an exempt financial service (VAT Notice 701/49). Because no VAT is charged, there's nothing to claim back. Interest on a business loan is usually an allowable expense for Corporation Tax, so it can reduce your company's taxable profit.

‍

What are the alternatives to VAT loans?

HMRC Time to Pay, the Cash Accounting Scheme if customers pay slowly, invoice finance or a flexible business loan. The right one depends on why cash is short.

• HMRC Time to Pay: spread the bill with HMRC. It works best if you ask before day 15.
• VAT Cash Accounting Scheme: pay VAT when customers pay you, not when you invoice. You can join if your taxable turnover is £1.35m or less.
• Invoice finance: borrow against unpaid invoices if slow payers are the problem.
• A flexible business loan: borrow for the bill and repay early when cash comes in.

VAT loan FAQs

How do I record a VAT loan in my accounts?

Record the loan as a liability and the VAT payment as clearing what you owed HMRC. Book the interest as a finance cost. Your accountant can confirm the entries for your bookkeeping software.

‍

Is it risky to take a VAT loan every quarter?

It can be. If you borrow for every VAT bill, you're repaying last quarter's loan while the next bill builds up. That's often a sign of a deeper cash flow problem, and it's worth looking at pricing, payment terms or the Cash Accounting Scheme.

‍

Can I get a VAT loan if I've already missed the deadline?

Yes, you can still borrow to pay HMRC. Penalties and interest already charged stay, but paying sooner stops them from growing, and the second penalty grows daily from day 31.

‍

How quickly can I get a VAT loan?

It depends on the lender and how complete your application is. With iwoca, you apply online.
