Council Tax Discount vs Exemption — Which Do You Have?

By GetRighted Legal Research TeamLast updated July 2026

Summary

Discounts and exemptions are the two main forms of council tax relief, but they operate differently. A discount (LGFA 1992 s.11) reduces the council tax charge by a percentage — typically 25% for single occupancy or 50% when all residents are disregarded. An exemption (SI 1992/558) removes the charge entirely for the qualifying period. Exemptions take priority: if your property qualifies for both a discount and an exemption, the exemption applies and you owe nothing. Knowing the difference matters because it determines how much you save and which evidence you need.

Discount vs Exemption at a Glance

The key distinctions:

When a Discount Becomes an Exemption

The line between discount and exemption blurs in certain situations. A property with one SMI resident living alone receives a 50% discount (all residents disregarded) — but it may also qualify for Class E exemption under SI 1992/558, which provides 100% relief. Always check whether an exemption class applies before settling for a discount. The difference can be worth hundreds of pounds per year.

Check for Both Before Accepting Your Bill

Many households receive a discount when they are actually entitled to a full exemption. If you have the single person discount but your only housemate has SMI, check whether the property qualifies for Class E exemption. If you receive a 50% discount because all residents are students, check whether Class N exemption should apply instead (zero council tax, not 50%).

Decision Tree

Work through this to identify the correct relief:

  • ✓Is the property occupied only by students? — Class N exemption (100% relief)
  • ✓Is the sole occupant an SMI person? — Class E exemption (100% relief)
  • ✓Is the property unoccupied following a death? — Class F exemption (100% relief until 6 months post-probate)
  • ✓Is one non-disregarded adult living with disregarded persons? — 25% single person discount
  • ✓Are all residents disregarded? — 50% discount (or check if an exemption class applies)
  • ✓None of the above? — Full council tax applies

Frequently Asked Questions

Can I have a discount and an exemption at the same time?
No. If an exemption applies, the entire charge is removed — there is nothing left to discount. The exemption supersedes any discount. If conditions change and the exemption ceases, the discount may then apply.
I receive a 25% discount — could I actually be entitled to an exemption?
Possibly. Check whether all residents fall into an exempt category. If the only other resident has SMI, Class E may apply. If all residents are students, Class N may apply. Review the exemption classes in SI 1992/558 against your household.
Does the billing authority check which relief I should have?
Not always. Authorities apply relief based on the information they hold. If they do not know about a resident's SMI status or student status, they cannot apply the correct relief. You must proactively provide evidence and request the appropriate discount or exemption.
What if I was getting a discount but should have had an exemption for the last 3 years?
Apply for the exemption now and request retrospective application. The authority must recalculate your bills for the entire period and refund the difference between the discount you received and the full exemption you were entitled to.
