Example of an HMRC Corporation Tax Payment Reminder letter for charities

Important: Receiving this letter does not automatically mean your charity owes Corporation Tax. However, it should never be ignored.

Why Has My Charity Received a Corporation Tax Payment Reminder?

A charity may receive this letter for several reasons:

1. HMRC Registered for Corporation Tax

Many charitable companies are automatically registered within HMRC's Corporation Tax system after incorporation. HMRC may automatically issue reminders even where no tax is payable.

2. CT600 Return May Be Expected

If HMRC has sent a payment reminder, it is very likely HMRC also expects a CT600 Corporation Tax return to be filed for that accounting period.

Important Warning: If HMRC expects a CT600 return and the charity does not file it by the deadline, HMRC can issue late filing penalties even where no tax is payable, the charity made no profit, or the charity is volunteer run.

Does This Mean the Charity Actually Owes Corporation Tax?

A charity may not owe Corporation Tax where:

However: Even where no tax is due, HMRC may still expect a CT600 Corporation Tax return to be submitted. This is why reading the full guidance is important.

How to Tell HMRC No Corporation Tax Is Due

If the charity does not owe Corporation Tax, trustees can notify HMRC online. HMRC provides an official online service where companies and charities can tell HMRC that no Corporation Tax payment is due.

Tell HMRC no Corporation Tax is due – This may stop further payment reminders where appropriate.

Important: Telling HMRC that no Corporation Tax is payable does not automatically remove the requirement to file a CT600 return.

You May Still Need to File a CT600 Return

Many trustees mistakenly believe that because no tax is due, no Corporation Tax return is needed. This is not always correct.

If HMRC has formally requested a Company Tax Return, usually through a CT603 notice, the charity must normally file the CT600 return by the deadline.

Failure to file may result in late filing penalties, additional penalties for repeated late filing, and interest and enforcement action in some cases.

What Happens if the Charity Ignores the HMRC Letter?

Ignoring the letter can create serious problems for trustees and the charity. Possible consequences include:

Late Filing Penalties

HMRC may charge automatic penalties for late CT600 filing

Continued HMRC Notices

HMRC may continue issuing reminders and warning notices

Compliance Risks

Repeated failures can create governance concerns for trustees
