R&D Advance Finance: Get Cash Against Your Tax Credit
R&D advance finance lets UK limited companies borrow against an outstanding R&D tax credit claim before HMRC pays out. Lenders typically advance 70 to 85 percent of the expected repayment. It suits companies that have filed or are ready to file a claim and need working capital sooner than HMRC's standard processing window allows.
What R&D advance finance is
R&D advance finance is a short-term facility secured against a confirmed or near-final R&D tax credit claim submitted to HMRC under either the SME scheme or the merged RDEC scheme that replaced it from April 2024. The lender advances a percentage of the expected credit, then recovers the loan directly when HMRC pays.
It is not a grant and it is not equity. The company retains full ownership and the transaction sits off the trading profit and loss account as a liability against the receivable. Because repayment comes from a defined HMRC payment rather than trading revenue, lenders treat the credit itself as the primary security, which means trading performance matters less than it does for a standard term loan.
How much lenders will advance
Most specialist lenders advance between 70 and 85 percent of the net expected credit, with the exact percentage depending on claim quality, the adviser preparing the claim, and whether the claim has already been submitted to HMRC.
A claim prepared by a recognised R&D tax specialist and already acknowledged by HMRC will attract the higher end of that range. A claim still being drafted will attract a lower advance or may not be eligible at all. Lenders also deduct their fees from the gross advance at drawdown, so the net amount received will be slightly below the headline percentage. The remaining balance, after fees and the advance are settled from the HMRC payment, is released to the company.
Eligible companies and claim types
Only UK limited companies are eligible for R&D advance finance. Sole traders and partnerships cannot make R&D tax credit claims under current HMRC rules and therefore cannot access this facility.
Under the merged scheme that applies to accounting periods beginning on or after 1 April 2024, most companies now claim under a single RDEC-style framework at a 20 percent above-the-line credit rate. Loss-making SMEs may still access the enhanced SME support rate under the merged scheme in certain circumstances. Lenders require a copy of the CT600 and the supporting R&D report, along with confirmation the claim has been or is being filed. Claims under enquiry by HMRC are not eligible until the enquiry is closed.
Cost structure and typical terms
R&D advance finance is priced as a fixed fee rather than a monthly interest rate, because the loan term is short and tied to HMRC's processing timeline rather than a fixed calendar period.
Typical fees run from around 3 to 6 percent of the gross advance depending on loan size and claim complexity. The facility is usually structured for a term of three to nine months, reflecting the time HMRC takes to process and pay a claim. If HMRC delays beyond the expected window, most lenders offer a short extension at an additional cost. There are no early repayment penalties because the facility is cleared the moment HMRC pays. Legal and arrangement fees are usually modest compared with asset finance or commercial mortgage transactions.
How the repayment mechanism works
Repayment is directed from the HMRC payment straight to the lender, which is the feature that makes this product structurally different from other short-term business loans.
At drawdown the company signs a deed of assignment or a notice of assignment over the R&D tax credit receivable. This notifies HMRC or creates a contractual obligation to route the payment to the lender's nominated account. In practice many lenders manage this by requiring the company to use a designated bank account or by coordinating with the company's accountant. Once HMRC pays, the lender deducts the outstanding principal and fees and forwards the surplus to the company within a short settlement window, typically two to five business days.
When R&D advance finance makes sense
R&D advance finance suits companies that have a confirmed, credible claim and a specific working capital need they cannot meet from trading cash flow alone, such as funding a product development sprint, bridging a payroll gap, or avoiding a costly overdraft extension.
It is less suitable if the claim is speculative, if HMRC has raised a compliance query, or if the company needs funds for longer than twelve months. It is also worth comparing the effective cost against the company's existing credit facilities. If a revolving credit facility is available at a lower all-in cost, that may be preferable. However, for companies with limited banking relationships or those that have recently been declined for unsecured lending, an R&D advance can provide access to substantial cash at a predictable, capped cost.
Applying through FundBiz
FundBiz introduces UK limited companies to specialist R&D advance lenders and manages the document process to reduce the time between enquiry and drawdown, which typically runs five to fifteen business days from complete application.
To start, the company provides its most recent CT600 with the R&D supplementary pages, the supporting technical and financial R&D report, and confirmation of the adviser or accountant preparing the claim. FundBiz then presents the case to lenders most likely to approve it and returns indicative terms for comparison. Because eligibility is restricted to limited companies under HMRC rules, LLPs and partnerships are not able to use this product. All introductions are made on a best-efforts basis and approval is subject to lender due diligence.
| Claim size (expected HMRC payment) | Typical advance rate | Estimated net advance | Typical fee range | Indicative term |
|---|---|---|---|---|
| £50,000 | 70% | £35,000 less fees | 3.5 to 5% | 3 to 6 months |
| £100,000 | 75% | £75,000 less fees | 3 to 5% | 4 to 7 months |
| £250,000 | 80% | £200,000 less fees | 3 to 4.5% | 4 to 9 months |
| £500,000 | 85% | £425,000 less fees | 3 to 4% | 5 to 9 months |
Step-by-step
- Confirm with your accountant or R&D adviser that the claim is filed or ready to file and that no HMRC compliance check is open.
- Gather the CT600 with R&D supplementary pages, the technical narrative report, and the financial breakdown of qualifying costs.
- Submit an enquiry to FundBiz with the documents and the expected HMRC payment amount.
- Review indicative terms from matched lenders, comparing the advance percentage, total fee, and expected settlement timeline.
- Instruct FundBiz on your preferred lender. Sign the facility agreement and the assignment deed over the R&D receivable.
- Receive funds, typically within five to fifteen business days of a complete application. HMRC repays the lender directly when the credit is processed.
Example
A software development company with seven staff filed a merged-scheme R&D claim showing an expected HMRC credit of £120,000. The claim was prepared by a specialist adviser and already submitted. A lender advanced 80 percent, providing £96,000 gross. After a 3.8 percent fee of £3,648, the company received £92,352 at drawdown. Six months later HMRC paid the £120,000 directly to the lender, which settled the advance and fee and returned the £24,000 balance to the company.
Frequently asked questions
Can a company access R&D advance finance before filing the claim with HMRC?
Some lenders will consider a pre-submission advance if the claim is in a near-final state and prepared by a recognised specialist. However the advance rate will be lower, typically 70 percent or below, to reflect the additional uncertainty. Most lenders prefer to see a submitted claim with an HMRC reference before approving funds.
Does taking an R&D advance affect the HMRC claim itself?
No. The assignment is a financial arrangement between the company and the lender and does not alter the claim content or the amount HMRC will pay. HMRC assesses the claim on its own merits. The lender simply receives the payment in place of the company once the credit is approved and processed.
What happens if HMRC reduces or rejects the claim after the advance is paid?
If HMRC reduces the credit, the company must make up the shortfall from its own funds because the advance was based on the original expected amount. If HMRC rejects the claim entirely, the full advance becomes immediately repayable by the company. Lenders factor this risk into their due diligence, which is why claim quality and adviser credentials matter at the application stage.
Is R&D advance finance regulated by the FCA?
R&D advance finance is a business lending product and, because it is advanced to a limited company rather than a consumer, it falls outside FCA consumer credit regulation. However the lenders and brokers involved may hold FCA authorisation for other activities. FundBiz operates as a credit broker and is authorised by the FCA for the regulated activities it carries out.
How long does HMRC typically take to pay an R&D tax credit claim?
Processing times vary. HMRC aims to process straightforward claims within 40 days of the CT600 being filed, but complex claims or those subject to additional review can take three to six months or longer. Lenders set facility terms to accommodate the expected timeline and most offer a short extension if HMRC payment is delayed beyond the original maturity date.
