Businesses in Markham, ON that are registered for HST must file accurate returns, claim all eligible input tax credits, and remit on time to avoid CRA penalties and interest.

Whether your business is a large concentration of IT firms, startups, and multicultural business communities, we have the expertise to ensure your HST returns are accurate, your input tax credits are maximized, and your remittances are made on time.
Good HST compliance also reduces the risk of CRA audits and adjustments. When your HST records are organized and your returns are prepared accurately, CRA is less likely to select your business for review. And if CRA does review your HST account, organized records and accurate returns make the process much easier to manage.
Every Markham GST/HST filing engagement begins with a review of the business's HST registration status, filing period, and transaction history. We assess whether all sales are correctly classified as taxable, zero-rated, or exempt, and whether all eligible input tax credits are being claimed.

We also review the business's HST remittance history. If HST remittances are late or missing, we help Markham clients understand the penalties and interest that have accumulated and develop a plan to get current with CRA. In some cases, a voluntary disclosure application may be appropriate to reduce penalties and interest on unfiled HST returns.
