Assalamu alaykum. My work is as a property surveyor and valuer for a government body where I provide property valuations and advice on land and buildings to government and local authorities for the purposes of determining liability to tax such as business rates tax, inheritance tax etc.
Business rates are used by local governments to support local public services eg street lights, roads etc.
Needed guidance in regards to the permissibility of this role please?
The valuations of properties I produce is relied upon by government and local authorities to support / charge local taxes such as business rates, inheritance tax, capital gains etc. As taxes are generally forbidden in Islam (I may have understood it wrong) am I therefore assisting in sin?
