Okay, you estimate your taxes and are now ready to pay them. Consider this: You might want to try paying your taxes monthly instead of quarterly. You will find smaller payments can be more manageable creating less stress on the pocket book and less stress on you. You also might want to try an EFTPS (Electronic Federal Tax Payment System) instead of snail mail. No checks will be misplaced and you'll get an instant receipt of payment. One final suggestion would be to keep a record of all your estimated tax payments so you could use them for the upcoming year.
