When is your income tax refund issued?

The closer it is to the deadline (normally April 15) the longer your processing will take. Electronic returns may require as little as 7 to 10 days, while mailing in a paper form can extend this to 3 to 4 weeks at the start of the tax season (January) and up to 6 to 8 weeks by the middle of April.

File early to reduce your wait.
