Backdating Council Tax Discounts
If you have been entitled to a discount or exemption for years without claiming it, you may be able to backdate your claim. Different rules apply depending on the council and the type of discount. For Council Tax Reduction, backdating is typically limited to 6 months (pension-age) or 1 month (working-age) unless there is good reason for delay. For SMI disregard and student exemption, councils have discretion to backdate further in some cases. Always ask your council how far back they will backdate.
Frequently Asked Questions
Yes. If the council refuses an SMI disregard application, you can appeal to the Valuation Tribunal for England (free) within 2 months of the decision. You will need medical evidence from a GP confirming the impairment, and evidence that the person receives a qualifying benefit. SMI disregard refusals are often successfully challenged at tribunal, particularly where the medical evidence is clear. Citizens Advice can help you prepare an appeal.
Empty properties: most councils charge full council tax or a premium (up to 300% after 5 years empty) on empty properties. Some short-term exemptions apply (e.g. after a death, while probate is being dealt with, or during major repairs). Second homes: councils can charge a premium of up to 100% extra on top of the standard rate. These rules changed significantly from April 2024 — check your specific council’s policy.
