Are Tenant Deposits Taxable? How Landlords Treat Deposits (2026/27)

Last updated 24 June 2026 · 7 min read · By the LandlordTaxAi Editorial Team

The short answer

A tenancy deposit isn’t taxable income when you take it — you’re holding it on the tenant’s behalf, protected in a deposit scheme. It only becomes taxable rental income if you keep part of it at the end (for example for unpaid rent or damage), and even then you can usually claim the matching cost.

Deposits confuse a lot of landlords at tax time: the money’s sitting there, so is it income? The short answer is no — not while it’s a held deposit. But the moment you retain some of it, the tax picture changes, and getting it right keeps your figures clean under Making Tax Digital.

This guide explains when a deposit is — and isn’t — taxable, and how to record retained amounts. For the wider rules, see do I need to declare rental income?.

Why a held deposit isn’t income

When a tenant pays a deposit, you don’t own that money — you hold it as security and, for most assured shorthold tenancies, must protect it in a government-approved tenancy deposit scheme. Because it’s the tenant’s money held on trust, it isn’t part of your rental income when received.

At the end of the tenancy, if you return the deposit in full, nothing has been earned and there’s no tax effect at all.

A deposit is different from rent in advance, which is taxable income when received (on the cash basis) because it’s payment for letting, not a security held on trust.

When a retained deposit becomes taxable

If you keep some or all of the deposit at the end of the tenancy, what you retain may become taxable rental income — but it depends on why you kept it.

You retain the deposit for...Tax treatment
Unpaid rentTaxable as rental income (it replaces the rent)
Repairing damageTaxable income — but claim the repair cost as an expense
Cleaning / replacing itemsTaxable income — claim the matching allowable cost
Nothing (returned in full)No tax effect

The key is to record both sides: the retained amount as income and the cost it covers as an expense. Done properly, retaining a deposit to fix genuine damage is often roughly tax-neutral.

Recording deposits under MTD

From April 2026, over-£50,000 landlords keep digital records and file quarterly. Don’t record incoming deposits as income — log them separately as held funds. Only bring an amount into your income when you actually retain it at the end of a tenancy, and record any related repair or cleaning cost in the same period.

Keeping deposits out of your income until they’re retained avoids overstating profit quarter to quarter.

Keep deposits out of your profit — until they count

LandlordTaxAi tracks held deposits separately and only books retained amounts as income, matched to the cost they cover — so your quarterly profit is always right.

See how it works

A worked example

At the end of a tenancy, Omar keeps £400 of a £900 deposit: £250 for unpaid rent and £150 to repair a damaged door (which costs him £150).

Deposit received earlier£900 — not income when taken
Returned to tenant£500 — no tax effect
Retained for unpaid rent£250 taxable income
Retained for damage£150 taxable income
Repair cost claimed−£150 expense
Net taxable from retention£250

Omar is taxed on £400 retained, but the £150 repair is deductible, so the net taxable amount is £250 — the part that simply replaced lost rent.

Frequently asked questions

Is a tenancy deposit taxable income?

No — not when you receive it. You’re holding it on the tenant’s behalf (usually in a protection scheme), so it isn’t rental income until you retain part of it.

When does a deposit become taxable?

When you keep some of it at the end of a tenancy — for unpaid rent, damage or cleaning. The retained amount is taxable rental income.

Can I claim the cost the deposit covered?

Yes. If you retain a deposit to repair damage or clean, record the retained amount as income and claim the matching cost as an expense.

Is rent in advance treated like a deposit?

No. Rent in advance is taxable income when received (on the cash basis) because it’s payment for letting, not a security deposit held on trust.

How do I record deposits under MTD?

Log incoming deposits as held funds, not income. Only bring retained amounts into income at the end of the tenancy, with any related cost in the same period.

What if I return the deposit in full?

There’s no tax effect at all — you never earned it, so nothing is taxable.
