Struggling single mum's Facebook tax return post goes viral

When Christina Knaack shared on Facebook what she'd done with her US$5600 (NZ$7501) tax return, she wasn't expecting to go viral.

The single mum from South Carolina received a tax cheque for US$5600, but instead of opting for a spending spree she splurged on securing the roof over her kid's heads, paying her rent for the year.

"Instead of buying my kids the latest Jordans or fancy electronics, I paid my rent for the YEAR," she wrote.

"I'm a single mom and I do it all by myself on a minimum wage job. I know that a roof over my kids' head is what's important.

"My kids don't want for anything because my priorities are straight. And this also means I will have that extra US$450 (NZ$625) a month to do things with my kids."

Knaack has a four-month-old baby and a two-year-old daughter.

Many were quick to congratulate the mum, who is also a recovering addict, on her decision.
