Construction Industry Scheme (CIS) Under the Construction Industry Scheme (CIS), contractors deduct money from a subcontractorâs payments and pass it to HM Revenue and Customs (HMRC). The deductions count as advance payments towards the subcontractorâs tax and National Insurance. Contractors must register for the scheme.
Depreciation and Amortization. Not all G&A expenses represent cash leaving the company. Depreciation and amortization expenses are a result of the matching principle of accounting. This principle tells us that we should match the costs of producing revenue to the period when the revenue is produced.
Amortization is a method of recovering (deducting) certain capital costs over a fixed period of time. It is similar to the straight line method of depreciation. The various amortizable costs covered in this chapter are included in the list below. However, this chapter does not discuss amortization of bond premium. For information on that topic, see chapter 3 of Publication 550, Investment Income and Expenses.
