To be fair to Cornwall Council, it is far from the only authority with a large arrears balance. Across England, billions of pounds in council tax goes uncollected each year. What makes Cornwall’s situation notable is the combination of a relatively low-wage local economy, high property values in certain areas (which push council tax bands up), and a large retired population, some of whom are on fixed incomes.
The council has repeatedly stated it does not write off debts and will take all reasonable steps to recover money owed. Its collection teams maintain that their track record is strong despite the economic challenges the county faces.
For residents, the practical takeaway is straightforward: if you owe council tax, your council will eventually come looking for it. The sooner you address it, the more control you have over how it gets resolved.
