The Short Answer: Yes, and Often the Payment Is Cash
The mechanism is straightforward in principle. The 20% R&D credit (or 27% under ERIS) is calculated on qualifying expenditure. For a profitable company, it reduces the corporation tax bill. For a loss-making company with no tax bill to reduce, the legislation provides a route for the unused credit to be paid out as cash, subject to specified conditions and adjustments.
This is not a loophole or an unusual interpretation. It is the intended operation of the scheme. The UK government explicitly designed the payable credit to support companies in the early stages of R&D investment, before they reach profitability.
How Loss-Making Companies Access R&D Relief Under the Merged Scheme
Under the merged RDEC scheme, the credit calculation follows a statutory step process set out in CTA 2009, Chapter 6A. For a loss-making company, the steps work as follows.
The 20% credit is calculated on qualifying expenditure. This credit appears above the line in the profit and loss account as income. The first application of the credit is against any in-year corporation tax liability. For a loss-making company, this liability is nil, so the credit passes to the next step.
The excess credit can then be applied against other current-year taxes the company owes, carried back against prior-year tax, or after working through the statutory sequence, paid out as a cash amount to the company. The exact net cash amount depends on the company's specific tax position, including the PAYE cap calculation. A specialist will compute this precisely.
The payment from HMRC typically arrives within 40 working days of a complete and compliant claim submission. Companies that plan their cash flow around the receipt should allow up to 12 weeks in their projections to account for HMRC processing variability.
The ERIS Scheme: Higher Rates for R&D-Intensive Companies
For loss-making companies where qualifying R&D expenditure represents at least 30% of total expenditure, the Enhanced R&D Intensive Support scheme provides a credit rate of 27% rather than 20%. ERIS exists specifically to support businesses in the early, pre-profit phase where R&D spending is high relative to total costs.
The intensity calculation uses total expenditure for the accounting period as the denominator. This means the 30% threshold is not just about the proportion of staff time spent on R&D; it encompasses all company costs in the period. Staff, rent, professional fees, marketing, and all other operating expenditure are included in the total.
Worked Example: ERIS at 35% Intensity
A SaaS company is in its second full year of operation. It has 12 staff, 8 of whom are engineers working on the core platform. The company is loss-making and pre-revenue.
| Item | Amount |
|---|---|
| Total company expenditure for the year | £1,400,000 |
| Qualifying R&D expenditure (staff costs apportioned for qualifying time + cloud costs) | £490,000 |
| R&D intensity (490,000 / 1,400,000) | 35% — exceeds 30% ERIS threshold |
| ERIS credit (27% of £490,000) | £132,300 |
| Standard merged scheme credit (20% of £490,000) | £98,000 |
| Additional benefit from ERIS vs standard rate | £34,300 |
The company has no corporation tax liability. After applying the PAYE cap calculation (staff are on UK PAYE with a combined PAYE and NIC liability that comfortably exceeds the cap threshold), the bulk of the £132,300 credit is receivable as a cash payment from HMRC.
What Happens if You Do Not Qualify for ERIS
Loss-making companies that do not meet the 30% intensity threshold claim under the standard merged scheme at 20%. The payable credit mechanism is the same: the unused credit passes through the statutory steps and can in most cases be received as cash.
The net cash benefit under the standard merged scheme for a loss-making company is lower than under ERIS, and lower than what was available under the old SME payable credit in previous years. However, it remains a meaningful amount. For a company with £300,000 of qualifying R&D expenditure, a 20% credit of £60,000, even after the PAYE cap adjustments, represents a material cash receipt.
Companies with R&D intensity between 20% and 30% should assess whether changes to their activity mix or cost base could bring them above the ERIS threshold in future periods. A specialist adviser will model this as part of the ongoing claim strategy.
Cash Payment Mechanics
Understanding how the cash payment works in practice helps with planning.
The credit is submitted as part of the amended corporation tax return, alongside the Additional Information Form. HMRC processes the claim and issues a repayment to the company's bank account. There is no separate application for the cash payment; it is the automatic result of the claim mechanics when the credit exceeds the corporation tax liability.
HMRC's standard processing time for a straightforward R&D claim is 40 working days. In practice, claims submitted during busy periods (particularly in the January to March window, when many 31 December year-end claims are filed) can take longer. Claims that trigger a compliance query from HMRC take longer still, which is one reason why the quality of the claim preparation matters.
The PAYE cap must be assessed before the claim is submitted. The cap limits the payable credit to three times the company's total PAYE and National Insurance liability for the year, plus £20,000. For companies with genuine R&D staff on UK PAYE, this cap rarely binds. For companies where founders are not on PAYE, or where development work is performed by overseas contractors, the cap may limit the cash payment significantly.
Early-Stage Companies: The First Two to Three Years Are Often the Best Claim Years
There is a counterintuitive truth about R&D tax credits and early-stage companies: the periods when a company is most likely to qualify for the highest rates are the same periods when it is most likely to be unaware of the relief or too busy to pursue it.
In a company's first two to three years, R&D expenditure is typically at its highest as a proportion of total costs. Staff are building the core product. Revenues are minimal. The cost base is dominated by engineering salaries and associated costs. This is precisely the profile that qualifies for ERIS.
As the company scales, hires sales and marketing staff, and grows its revenue base, the R&D intensity ratio naturally falls. The credit may still be available under the standard merged scheme, but the ERIS premium is lost.
The two-year filing deadline means that companies which fail to claim in their early years lose those periods permanently. An early-stage company that discovers R&D tax credits in year four can only recover years two and three; year one is gone.
Worked Example: Pre-Revenue SaaS Company
Pre-Revenue SaaS Company, Year to 31 March 2026
| Item | Detail | Amount |
|---|---|---|
| Total company expenditure | Staff (12 FTE), cloud, office, professional fees | £1,100,000 |
| Qualifying R&D staff costs | 7 engineers, 80% qualifying time, salaries + employer NIC + pension | £336,000 |
| Qualifying cloud costs | AWS infrastructure directly attributable to qualifying activities | £28,000 |
| Total qualifying expenditure | £364,000 | |
| R&D intensity | 364,000 / 1,100,000 | 33.1% — qualifies for ERIS |
| ERIS credit (27%) | 27% x £364,000 | £98,280 |
| Corporation tax liability | Company is loss-making | Nil |
| Estimated cash receipt | Subject to PAYE cap and statutory adjustments; specialist to calculate | Approx. £90,000 to £98,000 |
For a company burning approximately £90,000 per month, this single R&D tax credit payment represents approximately one month of additional runway. For companies that have two open periods, the combined receipt could be significantly higher.
Common Mistakes Loss-Making Companies Make
Beyond the fundamental misconception, loss-making companies commonly make the following additional errors.
Failing to check ERIS eligibility. Companies that would qualify for the 27% ERIS rate submit at the standard 20% rate because they have not had the intensity calculation done. A few additional thousand pounds per period, compounded across two or three open periods, represents a significant difference in total recovery.
Not placing founders on PAYE. The PAYE cap limits the payable credit to three times the company's PAYE and NIC liability. Founders who draw dividends rather than salary reduce the PAYE base and, with it, the maximum payable credit. A specialist will flag this before submission and advise on the position.
Missing the Claim Notification deadline. First-time claimants for periods beginning on or after 1 April 2023 must submit a Claim Notification Form within six months of the accounting period end. This sits inside the two-year filing window but must be done first. Missing the notification deadline can affect the current-period claim.
Waiting until profitable to start claiming. There is no benefit to waiting. The qualifying expenditure in an open period does not increase with time, and the deadline clock continues to run.
Frequently Asked Questions
Yes. Under the merged scheme, a loss-making company can receive a cash payment directly from HMRC based on its qualifying R&D expenditure. The credit is calculated at 20% (or 27% under ERIS), and where it exceeds the corporation tax liability, the excess can in most cases be paid out as a cash transfer to the company's bank account, typically within 40 working days of a complete submission.
Yes. The payable credit is subject to a PAYE cap: the maximum payable credit in any period is three times the company's total PAYE and National Insurance liability for the year, plus £20,000. Most companies with R&D staff on UK payroll will not be affected. Companies where founders are not on PAYE, or where development is primarily offshore, should have the cap assessed before relying on a projected cash receipt.
You can claim for any open accounting period within the two-year filing window. For most companies, the two most recent periods are still open. The third (earliest) period may have passed its two-year deadline. Establishing the exact open periods and their deadlines is the first step. For more detail, see our guide: The R&D Tax Credit Deadline.
Pre-revenue companies can claim R&D tax credits. The legal test is whether the company is carrying on a trade or has a genuine intention of doing so. For most early-stage technology, life sciences, and engineering companies, this test is met from the point the company is actively developing its product. A specialist will confirm your specific position.
The ERIS intensity threshold requires that qualifying R&D expenditure is at least 30% of the company's total expenditure for the period. Total expenditure includes all company costs: staff, rent, professional fees, marketing, and all operating expenditure. The intensity ratio changes from year to year as the company's cost mix evolves. A specialist calculates this separately for each period.
