How do I file my husband's taxes when he is an incorporated business owner, who has taken zero income from the business? I have no T4 or T4A?

Hi, thank you for using intuit TurboTax Community

All incorporated businesses must file a T2 corporate tax return annually. Individuals file a T1 return and usually report income from all sources. Even if there were no dividends or employment income paid from the corporation, the individual taxpayer could have other sources income

Hope this helps
