The highest tax rate is 50% and the lowest is 0%

Tax is modelled in the game because it is a significant business expense in reality.

Business unit income is taxable. Rental income is taxable. Bond coupon income is taxable. Income from patents is taxable.

Capital gains made from buying and selling land isn't taxable. Capital gains made from share trading isn't taxable.

Dividend income isn't taxable, because a dividend is a payment of out net profit.

Most expenses incurred in generating income are tax deductible. Wage expense is tax deductible. Bond coupon payment expense is tax deductible. Patent fee expense is tax deductible. Advertising expense is tax deductible. (Advertising expense occurs when a brand is realised as an expense.)

New companies, specifically companies created within 7 real days, don't have to pay tax.

For companies that do have to pay tax, the company tax rate depends on the percentage of shares held by the small shareholders bot. Specifically, the rate is 50% less half the percentage of shares held by the bot. Thus, if the bot holds 10% of the total issued shares of a company, the company's tax rate is 45%. If the bot holds 20%, the rate is 40%.

The highest tax rate is 50% and the lowest is 0%.

Tax is applied at the end of every game day. If at the end of a day, a company has a tax loss, the company will receive a tax rebate equal to the applicable tax rate multiplied by the tax loss. The purpose of the rebate is to ensure that costs, especially the cost of supplies, offset revenues. If at the end of a game year, a company has an overall tax rebate (ie, a negative tax figure), the rebate will be reversed in full so that the tax expense of the company is zero. If a company liquidates and it has a net tax rebate for the year thus far, the rebate will also be reversed.
