Hello, I didn't claim my tax refund in 21 days and had a cheque sent out to me recently, it usually takes 3-6 weeks for it to arrive. The problem is I'm changing addresses for the month of August, then going abroad for a month and then changing my address again. The cheque delivery is highly inconvenient and requesting a replacement letter is basically a gamble. Is it possible under special circumstances get an online claim after 21 days?
