AFFORDABLE Corporate Tax Cleanup Services
Corporate tax cleanup is the process of going back through returns that have already been filed — sometimes several years’ worth — to find where the numbers went wrong, correct them, and resolve whatever balance, penalty, or CRA notice resulted. It’s different from tax planning, which looks forward, and different from tax filing, which is a single year done right the first time. Cleanup is what happens when a prior year wasn’t done right, and it needs to be fixed before it compounds.
At Beta Taxes, our certified public accountants work with incorporated businesses across Toronto, Mississauga, Brampton, Vaughan, Etobicoke, Scarborough, Ottawa, Hamilton, Markham, and Windsor to untangle past filings — whether that means one overlooked deduction or several years of inconsistent bookkeeping behind a string of T2 returns. Our goal is straightforward: find every error, correct it the right way, and leave you with a clean file and a process that keeps it clean going forward.

Why Accurate Corporate Tax Cleanup Matters
A T2 return that was filed doesn’t mean it was filed correctly. Missed deductions, a GIFI code mapped to the wrong line, a shareholder loan that was never repaid on paper, or revenue that doesn’t match your GST/HST filings — these sit quietly until CRA’s matching system flags them, and by then the fix costs more: reassessments, arrears interest compounding daily, and in some cases gross-negligence penalties.
Cleanup changes that trajectory. By going back through your prior returns, bookkeeping, and CRA correspondence together, we catch what a single-year filing review would miss, correct it through the proper amendment process, and put your corporation back on solid footing — before CRA finds it first.

FAQ’s
Frequently Asked Questions
What's the difference between corporate tax cleanup and corporate tax filing?
Filing is doing the current year's T2 correctly the first time. Cleanup is going back through years that have already been filed to find and correct what went wrong — errors, missed deductions, or mismatches that are now sitting in CRA's system.
How many years back can you correct?
Amended T2 returns can generally be filed within three years of the original Notice of Assessment for a CCPC. Beyond that window, correction is still sometimes possible in limited circumstances — we'll tell you exactly where your corporation stands once we've reviewed the filings.
Will a cleanup trigger a CRA audit?
A voluntary, well-documented correction is treated very differently than an error CRA finds on its own. In most cases, coming forward proactively reduces audit and penalty risk rather than increasing it.
Can cleanup reduce penalties and interest I already owe?
Often, yes. Depending on how the original error happened, we may be able to request relief on penalties and interest, or use the Voluntary Disclosures Program where unreported income is involved.
What records do you need to get started?
Your prior T2 filings and supporting schedules, your bookkeeping records for the same years, and any CRA correspondence you've received. We'll confirm exactly what's needed once we understand your structure.
Is this only for businesses with major errors?
No — small, single-item corrections (a missed deduction, a miscoded GIFI line) are just as much a cleanup as a multi-year overhaul. Even one overlooked item is worth reviewing, since it affects every year it carried forward into.
