In Alberta, individuals and businesses are required to file specific tax forms to comply with provincial tax regulations. For individuals, key forms include the AB428 – Alberta Tax and Credits Form, which is used to calculate provincial income tax and claim Alberta-specific credits. Additionally, the AB(S12) – Alberta Family Employment Tax Credit allows families to claim employment tax credits. Seniors can take advantage of the AB(S11) – Senior Homeowners Property Tax Deferral Program to defer property taxes on their primary residences, while the AT366 – Alberta Political Contributions Tax Credit offers credits for political contributions. Businesses in Alberta have their own set of forms, such as the AT1 – Alberta Corporate Income Tax Return, which is used for filing corporate income taxes, and the AT179 – Alberta Scientific Research and Experimental Development (SR&ED) Tax Credit, designed for companies engaging in research activities. Additionally, businesses can use the AT1 Schedule 6 to carry forward or back losses and offset income, while insurers must file the AT2 – Alberta Insurance Premiums Tax Return. These forms ensure both individuals and businesses comply with tax obligations while benefiting from the credits and deductions available under Alberta’s tax system. For more information and access to the forms, individuals and businesses can visit the official Alberta government websites.
