Rent Arrears and Bad Debt Relief: Tax on Rent Your Tenant Never Paid

A tenant who stops paying feels like a rent problem first and a tax problem second, if it registers as a tax problem at all. For some landlords it genuinely isn't one: no rent received, no tax due. For others, particularly companies and landlords on the accruals basis, the rent can already be sitting in taxable profit even though not a penny of it has actually arrived, and the only way out is a specific, evidenced bad debt claim.

The basis you're taxed on decides everything

Since the cash basis became the default for most unincorporated property businesses, the majority of individual landlords are taxed on rent as it's actually received, not as it falls due under the lease. Under that basis, a tenant who simply stops paying doesn't create a tax charge on the missing rent — there's nothing to write off because nothing was ever brought into account as income in the first place. We've covered the wider trade-offs of the cash basis, including how it treats capital spending and finance costs differently from the accruals basis, in our guide to cash basis accounting for landlords, and that comparison is worth reading before assuming cash basis is automatically the right choice.

Companies don't get that option. A UK property business run through a company is always taxed on the accruals basis, recognising rental income as it falls due under the lease regardless of whether it's been paid. The same applies to individual landlords who've opted out of the cash basis, or whose turnover takes them above the threshold at which cash basis stops being available. For all of them, an unpaid invoice for last quarter's rent is still taxable profit unless something is done about it.

What a specific bad debt deduction actually requires

Under the accruals basis, relief for rent that's accrued but genuinely won't be collected is available as a specific bad debt deduction, mirroring the equivalent relief available to any trading business with a doubtful debtor. The word doing the work there is specific. HMRC doesn't accept a general provision calculated as a percentage of arrears across a portfolio on the basis that some tenants typically default — the deduction has to relate to an identified tenant, an identified debt, and evidence that recovery is genuinely in doubt rather than merely late. That evidence might be a documented history of missed payments alongside failed attempts to collect, a County Court Judgment obtained but unsatisfied, correspondence showing the tenant disputes liability, or the tenant's own insolvency or bankruptcy.

Where that evidence exists, the accrued rent can be written down for tax purposes in the period the debt becomes doubtful, rather than waiting for years of pursuing a recovery that never quite gets formally abandoned. If part or all of the rent is later recovered — a payment plan resumes, a guarantor pays out, or the arrears are recovered from a deposit or through enforcement — that recovery has to be brought back into taxable income in the period it's actually received. The relief adjusts timing; it doesn't permanently exempt rent that does eventually get paid.

VAT bad debt relief is a separate claim, on a separate timetable

Where commercial premises have been opted to tax and VAT has been charged on the rent, the VAT position runs on its own rules, entirely separate from the Income Tax or Corporation Tax treatment above. VAT bad debt relief lets a landlord reclaim VAT already accounted for to HMRC on rent that remains unpaid, once the debt has been outstanding for six months from the date it was due and has been written off in the landlord's accounts, along with the other conditions of the scheme being met. It's a genuinely useful relief that gets missed by landlords focused entirely on the income tax side of a bad debt and not tracking the separate six-month VAT clock running alongside it.

Because the VAT and direct tax reliefs run on different tests and different timescales, it's worth tracking both from the point arrears first become a concern, rather than dealing with the VAT position as an afterthought once the direct tax bad debt claim has already been made.

Rent guarantee insurance changes the numbers, not the principle

Many landlords carry rent guarantee insurance precisely to protect against this scenario, and it's worth being clear on how a claim interacts with the tax position. Insurance proceeds received to cover lost rent are themselves taxable income, and the premiums paid for the cover are a deductible expense in the normal way. Where a claim pays out, it effectively substitutes for the unpaid rent from a tax perspective, and any bad debt deduction claimed on the underlying tenant debt should reflect what's actually still outstanding once the insurance recovery is taken into account, rather than double-counting the loss.

Getting the timing right

The relief exists to match tax to genuine economic loss, and it works best claimed promptly once a specific debt is clearly doubtful, rather than left for years on the basis that recovery might still happen eventually. Waiting for a final, formal resolution — a completed possession claim, a closed insolvency, an abandoned enforcement action — before claiming any relief at all means carrying a tax cost on income that was never realistically going to be collected. Documenting the point at which a debt turned from late to doubtful, and claiming relief from that point, keeps the tax position closer to the commercial reality of the arrears as they actually happened.

Common questions

Do I pay tax on rent I never actually received?

It depends which basis you're taxed on. Under the cash basis, which is now the default for most individual landlords, you're only taxed on rent actually received, so unpaid rent simply doesn't create a tax charge. Under the accruals basis, which companies always use and which some individual landlords opt into or are required to use, rent is taxed as it falls due under the lease, whether or not the tenant has paid it, unless a specific bad debt deduction is claimed.

What is bad debt relief for rental income?

It's a deduction available under the accruals basis for rent that's been recognised as income but is genuinely doubtful to be collected, supported by specific evidence such as arrears correspondence, a County Court Judgment, or the tenant's insolvency. It reduces taxable profit to reflect that the accrued rent is unlikely to actually be paid.

Can I claim VAT back on unpaid commercial rent?

Where the property has been opted to tax and VAT has been charged and accounted for on invoiced rent, VAT bad debt relief can be claimed once the debt has been outstanding for six months from the due date and has been written off in the accounts, subject to the normal conditions in the VAT bad debt relief scheme.

What happens if I later recover rent I'd already written off?

The recovery has to be brought back into account as taxable income in the period it's actually received. A bad debt deduction is a timing adjustment for genuinely doubtful debts, not a permanent write-off of tax due on rent that does eventually get paid.

Does using the cash basis solve this problem automatically?

For Income Tax purposes it largely does, since unpaid rent isn't taxed until it's received. But the cash basis carries other consequences, particularly around how capital expenditure and finance costs are treated, so it's worth weighing the full comparison before assuming it's the better basis for a particular landlord.

Do landlord companies get the same bad debt relief as individuals?

Broadly yes. A company always uses the accruals basis, and Corporation Tax generally follows the impairment loss recognised in the accounts for a specific, doubtful rental debtor. The same requirement applies: it has to be a specific, evidenced provision against an identified debt, not a general allowance against arrears as a category.
