If you've under-reported income by 25 percent, however, the IRS can go six years back, or seven if you claim a loss for bad debt or worthless securities. If you don't file, or if you file a fraudulent return, the IRS has no statute of limitations; so it may be best to keep your records indefinitely.
1 For a simple bladder infection, you will take antibiotics for 3 days (women) or 7 to 14 days (men). 2  If you are pregnant or have diabetes, or have a mild kidney infection, you will most often take antibiotics for 7 to 14 days.  Finish all of the antibiotics, even if you feel better.
