Question about tax rebate?

I was wondering if anyone on here is familiar with that tax rebate this year? I am not good with accounting/tax stuff (we always have someone do ours), but my question is...if you owe on your taxes, does that mean you don't get the rebate?

Last year my husband worked two jobs (I'm a stay at home mum and don't have an income). One of his job pays a substantial amount, and if we were filing just with that we would get a return. But his other job he's a subcontractor and the company didn't take out taxes. Last year when we filed, we owed on our taxes because of it. I'm assuming it will happen this year too. But since he worked two jobs (one that was taxed, and one that wasn't), wouldn't they take that job he worked that was taxed into consideration? I just don't get how it works.
