Professional Tax Preparation Services for Personal and Business Filing
Tax preparation covers reviewing your income documents, organizing deductions and credits, preparing the correct return for your situation, filing through the right CRA channel, and making sure you understand what comes next. For businesses, that often extends to bookkeeping review, GST/HST reporting, payroll source deduction calculations, T2 corporate filing, and support when CRA sends something back.
CRA describes professional tax preparers as firms or individuals who prepare returns and electronically send them to CRA on a client’s behalf. Before any filing starts, we give you a clear document checklist so nothing gets missed.

What We Handle During Tax Preparation
The scope of work depends on your filing type, and more than one of the following often applies to the same client in the same year.
We handle personal income tax return preparation, business income and expense review, sole proprietor tax filing support, corporate tax return preparation, GST/HST return preparation, input tax credit review, payroll source deduction filing support, T4 and year-end payroll support, CRA notice and reassessment review, prior-year and late tax filing support, non-resident tax filing review, rental income reporting support, tax document organization, and CRA post-filing follow-up support.
Documents Required for Tax Preparation

Personal Tax Documents
Bring government-issued identification if you are a new client, your Social Insurance Number, and your prior-year Notice of Assessment. Income slips include T4, T4A, T5, T3, T5008, and T2202 where applicable. Also bring RRSP contribution receipts, medical receipts, childcare receipts, tuition receipts, donation receipts, rent or property tax documentation where eligible, rental income and expense records if applicable, and any CRA letters or notices received during the year.
Business Tax Documents
Everything listed above for personal filing, plus business income records and invoices, expense receipts, bank and credit card statements, business loan and asset purchase records, a vehicle mileage log if you are claiming vehicle expenses, home office measurements and costs if claiming workspace expenses, payroll summaries if you have employees, and GST/HST filing records if you are registered. Include your prior-year return and Notice of Assessment as well.
Corporate Tax Documents
Year-end financial statements covering the income statement, balance sheet, and statement of retained earnings, a reconciled trial balance, general ledger, bank reconciliations, shareholder loan details, dividend resolutions and declarations, payroll summaries, GST/HST records, and asset addition and disposal records. Also bring the prior-year T2 return and Notice of Assessment.
CRA Notice and Audit Documents
The original CRA letter or notice, the previously filed return it relates to, any CRA account correspondence, supporting receipts and records the notice references, bank statements, and payroll or GST/HST records if CRA has mentioned them specifically in their request.
How Our Tax Preparation Process Works
From the moment you reach out to the point CRA confirms your filing, here is exactly what happens at each stage. Nothing gets submitted without your review and approval first.
Initial Filing Review
We identify whether you need personal, business, corporate, GST/HST, payroll, non-resident, or CRA notice support and confirm the full scope before preparation begins.
Document Collection
You provide your tax slips, receipts, financial records, prior returns, and CRA correspondence through our secure client portal, by in-person drop-off, or by mail.
Missing Item Check
We review what you have provided and flag missing slips, unreconciled accounts, unclear income sources, or incomplete records before we begin preparing the return.
Tax Preparation
We prepare the relevant return, schedules, remittance calculations, or response package depending on your filing type.
Client Review
We walk you through the filing summary, explain the refund or balance owing, answer questions, and get your approval before anything is submitted.
CRA Filing or Submission
We file the return or submit the prepared response through the appropriate CRA method for your situation.
Post-Filing Support
We monitor your Notice of Assessment, flag any discrepancies from what we filed, and prepare a follow-up response if CRA requests additional information.
Filing Deadlines & CRA Compliance Facts
Missing a deadline costs more than the filing itself. These are the official CRA dates and obligations for the 2025 tax year and the 2026 filing season.
Personal & Self-Employed
For most individuals, personal tax returns are due April 30, 2026. Self-employed individuals and their spouses have until June 15, 2026 to file, but any balance owing is still due April 30, 2026.

Payroll Remittances
Regular payroll remitters send remittances by the 15th day of the month following the pay period, according to CRA payroll guidance.
CRA Audits & Reassessments
CRA audits examine books and records to confirm whether tax obligations are being met and whether benefits or refunds have been calculated correctly.

Frequently Asked Questions
Clear answers to common questions about our tax preparation process, deadlines, and CRA compliance support.
What are tax preparation services?
Tax preparation services involve reviewing your documents, preparing the correct return or remittance for your situation, checking supporting information, filing through the appropriate CRA channel, and helping you understand your Notice of Assessment or any CRA follow-up that comes after.
What documents do I need for tax preparation?
Individuals generally need tax slips, receipts, prior-year Notice of Assessment, ID, and any CRA correspondence from the year. Businesses add income records, expense receipts, bank statements, payroll summaries, GST/HST records, and prior-year filings. CRA advises gathering all slips, receipts, and supporting documents before meeting with a tax preparer.
Do I need a tax preparer or can I use software?
Tax software handles straightforward personal returns well. A tax preparer adds more value when the file involves business income, rental income, corporate filings, GST/HST, payroll, non-resident situations, missing prior years, or CRA notices, because those require judgment and review that software does not provide.
When is the personal tax deadline in Canada?
For the 2025 tax year, most individuals must file by April 30, 2026. Self-employed individuals and their spouses have until June 15, 2026 to file, but any balance owing is still due April 30, 2026.
When is a corporate tax return due?
CRA requires corporations to file their T2 return within six months after the end of each corporate tax year.
Can tax preparation include GST/HST filing?
Yes. When a business is registered for GST/HST, preparation can include return filing, ITC review, remittance calculations, and catch-up filing for missed periods. Full details are on the CRA GST/HST guidance page.
Can you help if I received a CRA notice?
Yes. If the notice relates to a return, reassessment, document request, balance owing, GST/HST, payroll, or audit, we review it and prepare the appropriate response. What we do depends on exactly what the letter says.
Can you help with a CRA audit?
Yes. Audit support includes organizing records, reviewing CRA’s specific requests, preparing supporting documentation, and responding through the audit process. CRA states that audits examine books and records to confirm tax obligations are being met correctly.
