In this form, you need to fill out each element (1a-10). Summarize these amounts in 11. The figure in number 11 is an essential figure for calculating taxable income. 

Here, you can understand the calculation fully. The formula is (Gross receipts or sales - Return and allowance = Gross receipts from the production of business income). Then, use 1c minus the cost of goods sold to get the gross profit. 

After that, use the gross profit to add dividends, interest, gross rents, gross royalties, other income, etc. Or you can understand it as the method to add lines 3 through 10 to get the total income. 

3. Calculate the Total Deductions

Deductions are items that you can avoid paying the tax. Therefore, you are allowed to deduct these items from the total income. However, you cannot deduct whatever you like. What you need is to follow the tax law in your living region. Meanwhile, focus on the recent regulations for tax deductions as the rules could be changed each year. 

From the above tax form (IRS form 1120), you need to add lines 12 through 26. Then, you will get the amount in 27 for total deductions. Next, you need to use the total income to minus total deductions. After that, get the taxable income before considering the net operating loss and special deductions. 

Finally, add net operating loss deduction and special deduction together. Then, jump into the final step. 

4. Taxable Income

After knowing the total income and total deductions, it's pretty easy to get the taxable income. You need to use line 28 to minus line 29c. Then, know the actual taxable amount for this year you need to pay. 

Amount Owed or Overpayment

Before paying the actual amount of tax for your business, you must have paid the quarterly estimated taxes before. Thus, if the estimated taxes are larger than the actual number, it will enter the amount overpaid. Or, it will enter the amount owed.
