Parish councils are funded mainly through an annual precept – an additional council tax levied on local taxpayers. For Selling this is raised as part of the annual council tax demand from Swale Borough Council. Once a year, usually in December or January, the parish council discusses its needs for the next financial year (April-March) and sets a budget. It then considers how it is going to raise the necessary funding and sets the precept accordingly.

Throughout the year (usually every month), the council's accounts are reconciled with the bank statements and presented to the council for approval. At the end of the financial year, the council completes and publishes an Annual Return (audit report). In addition to this, councils with a turnover of less than £25,000 are required to publish further financial information. All financial information for Selling Parish Council can be found below.
