The B.C. government and H&R Block are teaming up to ensure people on income assistance file their taxes in order to get all the tax breaks available to them.

About one-quarter of the people on welfare don't file tax returns and are missing out on benefits like HST credits and child tax credits, Social Development Minister Kevin Krueger said in a release Monday.

Krueger said that by filing a return, a single person on welfare can get as much as $585 more a year, a single parent with one child could get $4,700 and a two-parent family with two children could get up to $8,600 more annually.

He said H&R Block is offering free income tax filing services for welfare recipients in its offices in 13 communities, including Vancouver, Victoria, Nanaimo, Surrey, Penticton, Kelowna, Kamloops and Prince George.

The service is available until Feb. 25.

The government says welfare recipients who get tax refunds through credits and other benefits won't have that money deducted from their income assistance cheques.
