Tax optimization represents high-quality method of company management, manifested in the reduction of the profit tax base and rights by which companies can be exempted from the value added tax payments, respectively right on refund of the tax prepayments. One of the methods of tax optimization is end of the year reinvestment of profits by which enterprise instead of paying profit tax and making consequential payouts to shareholders can reinvest complete (non-taxable) profits in order to increase share capital for the amount that have to be equal to the amount of investment in the fixed assets. The following optimization method is the use of the passive time accruals, which implies reduction of the profit tax base so expenses related to the activities lasting for several accounting periods are partially recognized and revenues recognized in the following accounting period, thus reducing tax burden of the current period. The next optimization method is the use of the accelerated depreciation rates, by which companies can increase retirements of their assets by periods, thus decreasing their profit tax base without making monetary expenses and hence depreciation is treated as a non-monetary expense. By making value adjustments or deduction of receivables from customers, which represent expenses (previously recorded as revenues), company can reduce its tax base if there was no possibility of collection from debtors. Furthermore, by optimization of inventory that by the time loses competitiveness through reduced quality, damage, expiry date etc., tax base can be reduced through adjustments or deductions. Tax base reduction can be achieved by book reserving, in a way to make estimations of the amounts of some costs related to future expenditures and thus if they are recognized as tax-deductible expenses by entering them to the current accounting period. Further option for reducing tax burden of companies may be investing in the intellectual capital that latter makes education and training costs, thus reducing the tax base. On the company results can be acted upon the system of transfer (internal) prices between affiliated companies, where there are inter-company transactions that can model the business performance of the profit centers. For the purpose of tax optimization some activities that are by nature of an export character or which accounts as the intermediation activities in someone else’s name and for the account of another may be exempt from the value added tax (thereinafter – VAT). Furthermore, the right to deduct tax is one of the fundamental elements in the value added tax system. By IV confronting the VAT in incoming and outgoing invoices and consequently by deducting the base for payment or return of the VAT, tax accumulation is avoided and ultimately entrepreneurial consumption of goods and services is not overload with VAT.
