Council Tax 2026 warning: who loses discounts after moving or working more

TL;DR Summary

• After Christmas, councils often reassess Council Tax discounts, especially following moves or changes in household circumstances.
• Single Person Discount (SPD) is the most commonly lost reduction, often without people realising why.
• Failing to report changes can lead to backdated bills, penalties, or repayment demands.

January is a peak month for Council Tax surprises. Many households only discover a discount has been removed when a higher bill arrives.

Searches for terms like “council tax discount loss” and “single person discount rules” tend to rise sharply after the New Year, particularly among people who moved home or changed work patterns in late autumn.

This guide explains the most common ways Council Tax discounts are lost, what happens if changes aren’t reported, and how you may be able to reinstate a reduction.

Why Council Tax discounts often change in January

While Council Tax is set annually, councils update records throughout the year. January is when many changes are processed together.

Common triggers include:

• End-of-year address updates after a move
• Data matching with other public records
• Reviews of Single Person Discount eligibility
• Changes reported late in the previous year

The Single Person Discount (SPD): when it breaks

The Single Person Discount reduces Council Tax by 25%, but it only applies when one adult is counted as living in the property.

Common ways SPD is lost

• Someone moves in: A partner, friend, or family member becomes a permanent resident.
• A temporary stay becomes “normal residence”: Extended stays can count as occupation.
• A student or exempt person stops qualifying: For example, finishing a course or changing visa status.
• Working patterns change: Increased working hours may affect exemption status in limited cases.

Many people assume SPD is automatic. In reality, eligibility depends on ongoing circumstances.

Moving home: a high-risk moment for discount loss

Moving around the end of the year is one of the biggest risk points for Council Tax errors.

Issues often arise when:

• The new address is registered late
• Household composition isn’t updated correctly
• SPD is assumed to carry over automatically

Each property is assessed separately. Discounts do not always transfer without confirmation.

What happens if you don’t report a change

Failing to report a change of circumstances can have financial consequences.

Possible outcomes include:

• Backdated bills removing the discount from the change date
• Lump-sum repayment demands
• Civil penalties in some council areas

In serious cases, councils can treat non-reporting as providing incorrect information.

How to check if you’re still entitled to a discount

A quick review can prevent surprises:

1. Check your latest Council Tax bill or online account.
2. Confirm who the council counts as living at the property.
3. Review any exemptions or reductions applied.
4. Compare this with your actual living situation.

Can you get a discount back?

In some cases, yes.

You may be able to restore a discount if:

• The council’s records are incorrect
• A second adult is actually disregarded under the rules
• You reported the change late but can provide evidence

Contact the council as soon as possible and provide supporting information.
