SEISS, CJRS and Eat Out to Help Out Overclaim Checks

HMRC continues to check Self-Employment Income Support Scheme, Coronavirus Job Retention Scheme and Eat Out to Help Out claims against the eligibility conditions that applied at the time. Where a claim exceeded what the recipient was entitled to, HMRC can recover the overclaimed amount and, depending on behaviour, apply a penalty for failing to notify the error.

Key facts

Schemes covered
Self-Employment Income Support Scheme (SEISS), Coronavirus Job Retention Scheme (CJRS or furlough) and Eat Out to Help Out.
Statutory basis
Schedule 16 to the Finance Act 2020 gives HMRC power to recover overclaimed amounts and charge penalties for failure to notify.
Notification obligation
Recipients generally had to notify HMRC of an overclaim within a set period once they became aware of it, or face a failure to notify penalty on top of repayment.
Data used
HMRC compares claims against turnover data, payroll records, till and VAT data, and trading pattern information reported elsewhere.
Penalty driver
Whether the overclaim was known about at the time, or only discovered later, and whether it was notified promptly, drives the penalty outcome.
Important: Deliberately claiming a grant you knew you were not entitled to, or knowingly failing to repay an amount you later realised was wrong, is treated far more seriously than a genuine mistake and can attract the highest penalty rates. Review any Covid-era claim promptly rather than waiting for HMRC to raise it first.

What happens, step by step

  1. 1

    Identify the scheme and claim period

    Immediately

    Confirm which scheme, which claim rounds and which periods HMRC is asking about, since eligibility conditions changed between different SEISS grants and CJRS phases.

  2. 2

    Re-test eligibility against the rules in force at the time

    Within a few days

    Compare your trading position, turnover impact or furlough arrangements against the specific conditions that applied for each claim, not the general scheme description alone.

  3. 3

    Check the calculation, not just eligibility

    Alongside the eligibility check

    Even an eligible claimant may have miscalculated the grant amount, for example using the wrong reference period or reference salary, leading to an overclaim in amount rather than in principle.

  4. 4

    Quantify any overclaim precisely

    Once the review is complete

    Work out exactly how much of the claim exceeded entitlement, by period, rather than repaying an estimated or rounded figure.

  5. 5

    Notify HMRC and arrange repayment

    As soon as an overclaim is confirmed

    Tell HMRC about the overclaim and repay it, or agree a Time to Pay arrangement if the full amount cannot be repaid immediately.

  6. 6

    Address any penalty position

    Once notification is made

    Explain when you became aware of the overclaim and how promptly you notified it, since this timing is central to whether, and at what rate, a penalty applies.

Why is HMRC still checking Covid-era grants?

HMRC retains statutory powers under Schedule 16 to the Finance Act 2020 to check and recover overclaimed SEISS, CJRS and Eat Out to Help Out amounts, and these checks continue well after the schemes themselves closed. HMRC compares claims data against later-filed tax returns, payroll submissions, VAT returns and till data to identify claims that look inconsistent with the actual trading position.

A check does not necessarily mean fraud is suspected; many overclaims arose from genuine misunderstanding of eligibility conditions that changed between rounds, or from calculation errors using the wrong reference figures. HMRC's approach and any resulting penalty depend heavily on how and when the recipient became aware of the issue.

SEISS eligibility and common overclaim causes

Self-Employment Income Support Scheme grants required the claimant to be adversely affected by coronavirus, with different specific tests applying to earlier and later grants, and to have traded in the relevant tax years with self-employment profits meeting the scheme's thresholds. A common overclaim cause is a business that had reduced but not genuinely 'adversely affected' trade, or one that continued at a similar level despite the claim.

Later SEISS grants required a reasonable belief that trading profits would be significantly reduced, a test that some claimants applied loosely at the time. Reviewing the actual turnover and profit outcome for the relevant period against what was reasonably believed when the claim was made is central to assessing whether a genuine claim was made or an overclaim resulted.

CJRS furlough claims and calculation errors

Coronavirus Job Retention Scheme claims required furloughed employees to genuinely stop working, or reduce their hours under flexible furlough, for the periods claimed. A frequent HMRC finding is that an employee continued to carry out some work during a period claimed as fully furloughed, which is a compliance breach even where the employer did not intend to defraud the scheme.

Separately, calculation errors — using the wrong reference salary, reference period, or failing to correctly pro-rate for partial periods or flexible furlough — can create an overclaim even where the underlying furlough arrangement was genuine. Employers should check both the eligibility of the furlough arrangement and the arithmetic of the claim itself.

Eat Out to Help Out checks

Eat Out to Help Out claims are checked against till records, VAT returns and other evidence of qualifying food and non-alcoholic drink sales during the scheme's operating days. HMRC compares the claimed number of qualifying covers and discount value against the business's other reported sales data for the same period.

Discrepancies often arise where a business claimed for sales that did not meet the scheme conditions, such as sales outside the qualifying days or times, or drinks not falling within the qualifying categories, rather than from a deliberate attempt to inflate the claim.

How overclaims are recovered and penalised

Where a claim exceeded entitlement, HMRC can raise an assessment to recover the excess. Separately, a penalty for failure to notify an overclaim can apply under Schedule 16 to the Finance Act 2020 where the recipient knew about the overclaim and did not tell HMRC within the applicable notification period, or knew about it before receiving the grant and did not adjust the claim.

The penalty position turns heavily on state of mind and promptness: a claimant who genuinely believed the claim was correct at the time, and who notifies and repays as soon as the error is identified, is in a materially different position from one who knew the claim was wrong and delayed telling HMRC.

Responding to an HMRC Covid grant compliance check

Treat a Covid grant check like any other compliance check: read the opening letter carefully to establish exactly which claims and periods are being questioned, gather the contemporaneous evidence used to make the claim, and reconstruct the eligibility position as it stood at the time, not with hindsight.

Where the review confirms an overclaim, notify HMRC and arrange repayment promptly rather than waiting for a formal assessment; doing so before HMRC identifies the error itself can materially improve the penalty outcome compared with a prompted correction made only after HMRC's letter.

Frequently asked questions

Can HMRC still check SEISS and furlough claims years later?

Yes. Schedule 16 to the Finance Act 2020 gives HMRC specific powers to assess overclaimed amounts and these checks have continued well after the schemes closed, subject to the applicable time limits.

What happens if I find an overclaim myself?

You should notify HMRC and arrange repayment as soon as you become aware of it. Acting promptly and voluntarily is generally treated far more favourably than waiting for HMRC to identify the issue first.

Is every overclaim treated as fraud?

No. Many overclaims stem from genuine misunderstanding of eligibility conditions or calculation errors. Penalties depend on whether the recipient knew about the overclaim and how quickly it was notified once known.

Can my company be pursued personally from a director?

Where a company cannot pay a CJRS or Eat Out to Help Out related liability and HMRC considers officers were knowingly involved in the overclaim, personal liability notice provisions can be considered in serious cases.

Do I need to repay the whole grant or just the excess?

Generally only the overclaimed excess needs to be repaid where the claimant was partly eligible; a claim made with no eligibility at all would need to be repaid in full.

What records should I keep to support a Covid grant claim?

Turnover and profit records supporting the adverse effect or reduced activity test, furlough agreements and working pattern records, and till or VAT data supporting Eat Out to Help Out sales, for the periods claimed.
