I just skimmed some of this. When does your tax season open?

Here in the US employers and banks are supposed to have payroll tax information (W2 form for wages, form 1099 for contract work or interest) by January 31 and we have until April 15 to file taxes. If the government owes you a refund then you can file later without penalty, but if you own them then there is a penalty for filing late.

A lot of people will be claiming unpaid "stimulus" payments from last April and others from January. I have a friend in this situation, who will be scrambling to file to get the extra total $1800 (so far).

I've been able to file right after Jan. 31 some years, but I don't have all of the forms from sources of income (this year for contract work - the 1099 form).
