R&D Tax Credit Advance Funding UK FAQ

Can I get cash advance on a pending R&D tax credit claim UK?

Yes. Specialist R&D advance lenders provide 70-90% of expected claim value within 24-48 hours of facility setup, repaid when HMRC pays the claim 4-12 weeks later. Typical fee 4-8% of advanced amount.

Best UK R&D tax credit advance lenders?

Specialist: RD Capital, Forward Funding, Innovate Finance (lender). General invoice finance providers offering R&D specialism: Bibby Financial Services, Skipton Business Finance. Specialist R&D claim consultants (Catax, Leyton, ForrestBrown, EmpowerRD) sometimes also offer or broker advance funding alongside their claim preparation services. Get quotes from at least 2 because pricing varies materially by claim size and quality.

How does R&D advance funding work?

(1) You submit your R&D tax credit claim to HMRC via your accountant or claim specialist. (2) You apply to an R&D advance lender with the submitted claim value. (3) Lender advances 70-90% of expected claim within 24-48 hours. (4) HMRC processes and pays the claim 4-12 weeks later. (5) HMRC payment goes to lender's nominated account; lender takes principal plus fee, releases balance to you.

What R&D claim sizes qualify?

Most lenders fund claims £25k-£2m. Below £25k the fees often exceed the value. Above £2m, syndicated facilities or term loans become more cost-effective. Sweet spot: £100k-£500k claims for SME software and biotech companies.

Can I get R&D advance funding before HMRC processes the claim?

Yes, that's the whole point. Submit the claim to HMRC first (your accountant or specialist does this), then apply for the advance against the submitted claim. Some lenders will advance against unsubmitted claims if the underlying R&D activity is well-documented (rare; higher fees, more underwriting). Most require HMRC submission before advancing.

Cost of R&D tax credit advance UK?

4-8% of advanced amount per cycle. Effective annualised cost: a 6% fee on a 60-day cycle equals roughly 36% APR. High but justified for short-term cashflow needs against a near-certain receivable. Compare against the cost of equity dilution or missed runway: usually cheaper. Do not use as a long-term funding strategy.
