I used to be really good about recording receipts weekly.
Now they all get filed by month and long about this time of the year I do one or two months a week and enter them into MMK. For some reason, that works better for me. That way I have 12 months of electric, gas and water bills; cable, internet and cell phone bills, the mortgage statement, etc.
I guess I just get into 'tax mode' and it goes smoother than doing it weekly or monthly. But, that's just me
