Businesses are still required to file and pay taxes in the event of a postal dispute. Mail delays do not change tax deadlines or the assessment of penalties and interest. Tax returns and payments must be received by the Ministry of Finance by the due date. Penalty and interest charges are applied to late tax returns and tax payments. A tax return must be completed for each reporting period, even if there is no tax owing. If the return due date falls on a weekend or statutory holiday, then payment and remittance is due on the next business day.
We encourage you to sign up for the Saskatchewan eTax Services (SETS) to avoid any delays in meeting your tax obligations. SETS provides a secure, fast, easy and convenient online self-service portal to electronically file and pay your taxes. You can opt to receive email notifications of when returns are due.
Paper (non-electronic) returns and payments may be couriered to the Ministry of Finance, at your own expense, to the following address: 4th floor, 2350 Albert Street, Regina, SK, S4P 4A6.
