How tax is calculated
Tax on material, labor, equipment and Total Only figures is based on costs before overhead, contingency and profit.
Tax on the contract price is based on the estimate total, including markup.
To charge overhead and profit on tax, leave the tax rates at zero. Instead, use percent adjustments to raise your cost columns by the tax rate.
