Frequently Asked Questions

What are the late filing penalties for tax returns?

CRA charges a 5% penalty on the balance owing, plus 1% per month for up to 12 months. Repeat offenders face 10% plus 2% monthly. Ontario businesses can avoid these penalties by working with our Mississauga tax team to ensure timely, accurate filings.

How does CRA calculate interest on unpaid taxes?

CRA charges compound daily interest at the prescribed rate (currently around 10% annually) on unpaid balances, starting the day after the filing deadline. Interest compounds every day, so delays are expensive. GTA businesses rely on our bookkeeping services to track liabilities and minimize interest charges.

What is the CRA Voluntary Disclosure Program?

The Voluntary Disclosure Program allows you to come forward about unreported income or errors before CRA discovers them, potentially avoiding penalties (but not interest). Applications must be voluntary, complete, and involve a penalty of at least $500. Our Ontario tax specialists have helped dozens of clients successfully navigate this program.

Can CRA penalties be reduced or waived?

Yes—CRA offers taxpayer relief for penalties and interest if you can demonstrate extraordinary circumstances, financial hardship, or CRA errors or delays. Applications require detailed documentation and strong supporting evidence. Mississauga businesses work with our CPA team to prepare compelling relief requests that maximize success rates.

What is the statute of limitations for CRA reassessments?

For most corporations, CRA has 3 years from the date of the original assessment to reassess (4 years for individuals). However, there's no time limit if fraud or misrepresentation is suspected. GTA businesses protect themselves with our proactive compliance services and thorough record-keeping to prevent reassessment issues.
