Corporate Tax Preparation in Mississauga
Corporate tax work is much easier when year-end records are current and the person preparing the filing understands the bookkeeping behind them. Yass Financials supports Mississauga small businesses with corporate tax preparation and year-round financial organization.

Tax preparation starts with reliable records
What does corporate tax preparation involve? It means closing the books for the fiscal year, reconciling accounts, preparing year-end figures and preparing the corporation's tax return from them. Yass Financials connects that work to your bookkeeping, so the return is built on records that are already current.
Corporate tax should not begin with a box of unresolved transactions at year end. Organized bookkeeping, reconciled accounts and clear records make filing more efficient, and give owners better information throughout the year.
A connected year-end process
Where Yass Financials handles your ongoing bookkeeping, the goal is to keep your books year-end ready instead of rebuilding them when the deadline arrives.
If your books are kept elsewhere, we start by identifying the information required and any issues that need to be resolved before the tax work is finalized.

Frequently asked questions
When is a corporate tax return due?
The CRA requires a corporation to file its T2 return within six months of the end of its tax year (its fiscal period). Any balance owing is generally due earlier than that, so it is worth planning ahead of year end. CRA: when to file.
Can corporate tax preparation be combined with monthly bookkeeping?
Yes. It is one of the most useful combinations, because current books make year-end work more organized and reduce surprises. More about bookkeeping.
Can you work with books that were kept by someone else?
Yes, after a review. A consultation looks at the condition of the records and identifies what needs to be completed before the year-end tax work can be finalized.
Do you offer tax planning during the year?
Yes. Yass Financials offers year-round tax advisory. Specific advice depends on the business and is discussed directly with you. More about tax planning.
What do you need from me at year end?
Typically bank and credit card statements, sales and expense records, payroll reports, loan statements and details of any large purchases or unusual transactions. You receive an exact list for your business. Read how to prepare your books for year end.
