Quick answer: A surrenderable loss is the portion of a company's tax loss that can be exchanged with HMRC for a payable R&D tax credit rather than carried forward. Under the merged scheme it is the net above-the-line credit after notional tax, subject to a cap of £20,000 plus three times the company's PAYE and employer NIC for the period.
What is a surrenderable loss?
A surrenderable loss is the portion of a company's tax loss that may be surrendered to HMRC in exchange for a payable R&D tax credit. Under the old SME scheme, the surrenderable loss was the unrelieved loss attributable to the enhanced R&D deduction, converted into cash at the payable credit rate. Under the merged scheme from 1 April 2024, the equivalent concept is the net above-the-line credit after notional tax, which the company may surrender for payment instead of carrying forward as a reduction to future tax.
How does HMRC define a surrenderable loss?
HMRC guidance on surrenderable loss is at CIRD89600 for the old SME scheme and at CIRD90400 for the merged scheme. The legislation is at sections 1054 to 1057 of the Corporation Tax Act 2009 for the old SME scheme and its equivalents in Chapter 1A of Part 13 for the merged scheme. The PAYE and NIC cap applies to both.
What does a surrenderable loss look like in practice?
A loss-making SME in the year to 31 March 2025 has a merged-scheme above-the-line credit of £50,000 after notional tax. It elects to surrender this credit to HMRC and receives a cash payment of £50,000, subject to the PAYE and NIC cap based on its payroll for the period.
How does the PAYE and NIC cap affect a surrenderable loss?
The surrenderable amount is capped at £20,000 plus 300% of the company's PAYE and employer NIC liability for the period. A company with £30,000 of PAYE and employer NIC on its R&D staff has a cap of £20,000 + (3 × £30,000) = £110,000, comfortably above the £50,000 credit in the example above, so the full amount can be surrendered. Employer NIC itself is charged at 15% from 6 April 2025 (13.8% for earlier periods), so the exact PAYE/NIC figure feeding the cap calculation depends on which rate applied during the accounting period.
Surrender now or carry forward?
A loss-making company does not have to surrender the whole credit for cash; it can carry part of the loss forward against future profits instead. The right choice depends on how soon the company expects to become profitable - see loss-making R&D claim for the wider mechanics. Companies unsure which route suits their cashflow position can run the numbers through the free eligibility calculator. Companies close to breakeven often surrender only part of the credit and carry the remainder forward, preserving some future tax shelter while still taking enough cash now to fund the next development cycle - a decision usually modelled alongside the wider corporation tax position, not the R&D claim in isolation.
Frequently asked questions
Yes - once a loss is surrendered for a payable credit it cannot also be carried forward; the company gives up the future tax deduction in exchange for cash now, which is usually the right trade for a genuinely loss-making, R&D-intensive business.
The surrenderable amount is capped at £20,000 plus three times the company's PAYE and employer NIC liability for the period. Any amount above the cap cannot be surrendered for cash in that period.
Not necessarily. A company can surrender part of the credit for cash and carry the remainder forward against future profits, a choice that usually depends on how soon the company expects to become profitable and its wider cashflow position.
