Corporate Taxes are filed after all the Bookkeeping has been done and we have an Accurate Trial Balance and General Ledger. At that point, we can distinguish the expenses, the items that get depreciated, file the Tax Return, and then produce a K-1 for the Shareholder (in the case it's an S-Corp, or Partnership)
Whats best is that since we do your payroll, payroll taxes, sales taxes, and bookkeeping; when filing your corporate tax return, it's all in your software accurately done.
There are many different types of businesses. Some businesses file a Sales Tax Return on a Monthly/Quarterly/ or Annual Basis. Depending on the type of company.
Every company has a different schedule according to the type of business, which differentiates the percentage and regulations for that particular type of business.
