A CRA reassessment should be tested against the facts before it stands
Ajax taxpayers may receive a CRA assessment or reassessment after an audit, review, late filing, or information-matching process. CRA may disallow a business expense, treat a bank deposit as unreported income, deny a GST/HST input tax credit, adjust rental income, reassess a property sale, alter payroll treatment, or apply a penalty. A reassessment is serious, but it is not always correct. A Notice of Objection may be available when CRA’s conclusion does not fit the evidence, calculation, or applicable tax rules.
The notice date should be reviewed immediately. The taxpayer type, tax account, and assessment all affect the deadline. Many objections must be filed within 90 days, while some individual objections follow different rules. An extension of time can sometimes be requested after the ordinary period, but it has its own strict time limit and requires a credible explanation. Delaying while trying to understand CRA’s adjustment can leave the taxpayer with fewer options.
Tax Help Canada helps Ajax residents, contractors, business owners, landlords, property owners, and families review CRA reassessments and prepare structured objections. We look at the notice, audit history, CRA reasoning, records, calculations, deadline, collections pressure, and the result that should be requested from CRA Appeals.
Start with the notice, the audit issue, and the deadline
CRA reassessments can concern personal tax, business income, GST/HST, payroll, rental reporting, property sales, deductions, credits, or penalties. The reassessment may follow a request for documents, a phone call, an audit proposal, or information CRA obtained from another source. The first task is to identify what CRA changed and what material it relied on.
The return, audit letters, records supplied, CRA’s proposal or working papers, reassessment, and correspondence should be read together. A brief statement of disagreement may protect a deadline, but it does not explain the factual or technical problem. A well-built objection tells CRA Appeals the issue, the relevant facts, CRA’s error, the supporting documents, and the correction requested.
Reassessments often involve more than one account
An Ajax contractor may have vehicle, home office, tools, travel, meals, or subcontractor expenses denied. A business can receive an income adjustment after CRA compares invoices, deposits, sales records, GST/HST, or third-party data. A landlord may be reassessed on rent, repairs, capital improvements, personal use, or a property sale. An owner-manager may face payroll, worker classification, shareholder benefit, or remuneration adjustments.
The right evidence depends on the issue. Bank deposits can be sales, rent, GST/HST collected, transfers, loans, reimbursements, refunds, or funds received for another person. A reconciliation distinguishes those amounts. Expenses need invoices, payment evidence, and an income-earning purpose. Property files need a clear timeline, rental evidence, financing, invoices, and an explanation of actual use.
Build an objection around CRA’s reasoning
An objection should identify the assessment, deadline, and account; state the issue under appeal; explain the facts; identify mistakes in CRA’s analysis; and support the result requested. That can mean reversing an income adjustment, accepting expenses, correcting a GST/HST calculation, removing a penalty, or changing property treatment.
We prepare schedules that link invoices to sales, deposits to their source, expenses to support, and GST/HST or payroll figures to the relevant account. When documents are incomplete, we look for reliable alternate sources: bank statements, supplier records, client records, contracts, email, property documents, accounting backups, prior returns, and CRA slips. The objective is to give CRA Appeals a credible file that can be reviewed and tested.
Keep connected reporting consistent
A reassessment can start with one tax return yet affect several accounts. A sole proprietor’s personal income may connect to business banking and GST/HST. An incorporated owner can have corporate expenses, payroll, shareholder transactions, and personal reporting. Rental activity can connect to property, banking, and other income. Detailed explanations should be checked against the related books and filings before they are submitted.
This reduces the risk that an answer on one account creates a new inconsistency on another. It also helps identify potential tax, interest, penalties, payment, and collections issues before the file reaches CRA Appeals.
Objections and collections need separate attention
Filing an objection is an important way to protect a taxpayer’s appeal rights, but it does not make all collections pressure disappear. The treatment may depend on the account, taxpayer type, and reassessment, and interest can continue. CRA calls, payment demands, refund offsets, wage garnishments, or other enforcement concerns should be reviewed alongside the objection strategy.
We help Ajax taxpayers organize the evidence, objection, communication, payment, and collections discussions. Where an auditor is still involved, clarifying information early may be useful, but no one should allow that conversation to cause the formal deadline to be missed.
Review every Appeals outcome promptly
CRA Appeals may request more information, confirm the assessment, vary it, or issue another reassessment. Each result needs prompt review because it may create a new deadline for further appeal, affect interest and payment options, or change the collections position.
Get a clear objection plan
If you received a CRA assessment or reassessment in Ajax, a confidential review can make the next step manageable. We will review the notice date, account, adjustment, audit history, available records, and collections concerns. From there, you can decide how to protect the deadline and present a focused, evidence-based objection.
