Corporate tax and accounting in Mississauga
Mississauga's economy clusters around Pearson airport: logistics, wholesale distribution, import/export and a dense small-manufacturing base. For these businesses, inventory and sales tax drive the corporate return more than anything else.
Wholesale and distribution corporations live on inventory accounting. A consistent valuation method and a defensible year-end count directly move taxable income: overstate inventory and you pay tax on profit you did not make, understate it and you invite a reassessment. Importers also carry HST paid at the border, recoverable as input tax credits only if the documentation is clean.
Ontario administers the T2 federally, so there is no separate provincial return, but Mississauga's larger employers cross the Employer Health Tax threshold and most carry WSIB. We reconcile inventory, border HST, EHT and payroll in one pass so the filing is a review rather than a spring rebuild.
