R&D Advance Finance: Fund Your Tax Credit Early
Start here · What do you need?
An R&D advance lets UK limited companies borrow against an outstanding HMRC R&D tax credit claim, receiving part of the expected repayment before HMRC pays. The loan is repaid directly from the HMRC credit when it arrives. It suits companies that can't wait for HMRC to process the claim.
What Is an R&D Advance?
An R&D advance is a short-term loan secured against a submitted or near-ready R&D tax credit claim, allowing a company to access most of the cash before HMRC pays out. The lender reviews the claim, agrees what proportion of the claim it will lend, and advances that sum. When HMRC pays, the funds go directly to the lender to clear the balance, and any surplus returns to the company.
This product sits outside traditional overdraft or invoice finance because the underlying asset is a tax receivable rather than a trading asset. It isn't a grant and doesn't affect the R&D claim itself. The company remains fully responsible for the accuracy of the claim submitted to HMRC.
Who Qualifies for an R&D Advance?
Eligibility centres on having a credible, well-documented R&D tax credit claim prepared by a qualified advisor or in-house finance team, and the claimant must be a company: only companies chargeable to UK Corporation Tax can claim R&D relief (GOV.UK). Lenders set their own minimum claim size. The company must qualify under HMRC's R&D rules; for accounting periods beginning on or after 1 April 2024 the merged scheme and enhanced R&D intensive support replaced the old SME and RDEC schemes (GOV.UK).
Lenders will look at the quality of the underlying R&D documentation, the track record of the advisor who prepared the claim, and whether previous claims have been queried or enquired into by HMRC. A first-time claimant isn't automatically excluded but may face a lower advance rate. Sole traders, partnerships and LLPs can't use this product, because they aren't chargeable to Corporation Tax and so can't claim R&D relief.
How Much Can You Borrow and at What Cost?
R&D advance lenders lend a proportion of the expected net HMRC repayment, with the exact percentage depending on claim complexity, advisor quality, and whether the claim has already been submitted. A straightforward claim prepared by a reputable firm usually attracts a higher advance rate than a first-time or complex claim.
Pricing is usually expressed as a flat fee or monthly interest rate rather than an APR, because the term is short. Costs vary by lender and by how long HMRC takes to pay, and some lenders charge an arrangement fee on top, so compare the total cost in each offer. Because the BoE base rate is currently 3.75 percent (as at 18 December 2025), the effective annualised cost of an R&D advance is notably higher than base, so companies should weigh the cash-flow benefit against the total cost before proceeding.
The Application and Drawdown Process
The process from enquiry to drawdown can be quick once the documents are in order. The lender needs the completed R&D tax credit computation, the CT600 or draft CT600 showing the repayment position, the company's last two years of filed accounts, and confirmation from HMRC that the return has been received.
Once the lender is satisfied with the documentation, they issue a facility letter setting out the advance amount, fee structure, and repayment mechanics. The company signs a deed of assignment over the HMRC repayment, which means the repayment is redirected to the lender's nominated account when HMRC processes the claim. The lender then releases the advance net of any arrangement fee. No physical assets are charged, so the company's property or equipment isn't at risk.
Risks and Considerations
The principal risk is that HMRC queries, opens a compliance check on, or reduces the R&D claim, leaving a shortfall between what HMRC pays and what the company owes the lender. In that scenario, the company must fund the difference from its own resources. This risk is real: HMRC has increased R&D compliance activity in recent years, and claims prepared without adequate technical narrative are more likely to be challenged.
Companies should only proceed with an R&D advance when the claim has been robustly prepared and reviewed. If HMRC raises an enquiry after the advance has been drawn, the loan continues to accrue cost while the enquiry runs, potentially for many months. Some lenders include a clawback clause if the claim is materially reduced. It's advisable to obtain written confirmation from the R&D advisor on the defensibility of the claim before committing to the advance facility.
R&D Advance vs Waiting for HMRC Payment
For many SMEs the choice is straightforward: if the company has sufficient working capital to wait for HMRC to process the repayment, the advance may not be necessary. However, for companies in growth phases, those with large payroll commitments, or those repaying invoice finance facilities, the timing of the HMRC repayment can be critical.
An R&D advance converts a future receivable into immediate liquidity, which can be used for any business purpose including stock purchase, hiring, or settling a VAT liability. When the total cost of the advance is below the cost of the problem it solves, for example avoiding a late-payment penalty or a missed payroll run, the advance delivers clear value. Where the company simply prefers speed over waiting, the cost-benefit calculation is less obvious and should be worked through carefully with an adviser.
How FundBiz Can Help
FundBiz is not a lender and does not arrange finance. R&D advance lenders generally need a corporate legal form to take an assignment of the HMRC repayment, and only companies can claim R&D relief, so sole traders, partnerships and LLPs don't qualify. Our enquiry form is for UK limited companies, LLPs and partnerships with four or more partners, but only limited companies can use an R&D advance.
If you send an enquiry, we pass your details to a business finance broker, who will contact you about your options and may introduce you to lenders. Any lender makes its own decision. The broker pays FundBiz a fixed fee for each enquiry. You pay nothing.

Step-by-step
- Confirm your R&D tax credit computation is complete and the CT600 has been submitted or is ready to submit.
- Gather supporting documents: R&D computation, CT600, last two years of filed accounts, and HMRC submission acknowledgement.
- Approach a lender or broker with the expected claim value and advisor details.
- Review any terms a lender offers, including advance rate, flat fee, and any arrangement charge.
- Sign the facility letter and deed of assignment over the HMRC repayment.
- Receive the advance net of fees once the lender has full documentation.
- When HMRC pays the claim, the repayment is redirected to the lender; any surplus is returned to the company.
Illustrative example
This is an illustrative scenario, not a real client case. A software development company with 12 employees submitted an R&D tax credit claim of £85,000 net repayment. Needing funds to cover a quarterly payroll run before HMRC processed the return, they arranged an R&D advance at 82 percent, receiving £69,700 within three days. HMRC paid the full £85,000 eight weeks later. After repaying the lender, the company retained the surplus of approximately £14,800.
Frequently asked questions
Does taking an R&D advance affect my HMRC claim?
No. The advance is a separate loan transaction between your company and a lender. The R&D claim is submitted to HMRC in the normal way and processed on its own merits. The only change is that when HMRC issues the repayment, it's redirected to the lender via a deed of assignment rather than to your company bank account.
What happens if HMRC reduces or rejects my R&D claim?
If HMRC pays less than the advance amount, your company is responsible for repaying the shortfall to the lender from its own funds. This is the main financial risk of R&D advance finance. Some lenders build a buffer into the advance rate, for example advancing only 75 percent of an expected £100,000 claim, precisely to reduce the likelihood of a shortfall. You should discuss this scenario with your lender and R&D advisor before drawing the facility.
Can a first-time R&D claimant use this product?
Yes, though lenders tend to offer a lower advance rate to first-time claimants, rather than the rate a claimant with a track record might get. This reflects the absence of a track record with HMRC. Using a well-regarded R&D specialist advisor and providing thorough technical documentation can improve the lender's confidence and result in a higher advance rate.
How quickly can I receive the advance?
R&D advance facilities can complete quickly once the lender has full documentation. The main delays are usually gathering the HMRC submission acknowledgement and having the R&D computation in a form the lender can review. Starting the enquiry process before the CT600 is filed is possible but drawdown will be conditional on submission.
Is an R&D advance regulated by the FCA?
R&D advance finance is a business lending product and is not consumer credit, so it does not fall under FCA consumer credit regulation in the same way as a personal loan. However, lenders arranging credit to businesses may still hold FCA authorisation for other activities. FundBiz is not a lender and does not arrange finance.
