If the IRS hasn't raised any issues about your 2005 tax return by now, it is safe to shred it. Last, you should keep any tax return that includes a claim for deducting worthless securities for seven years. If you've lost or discarded a tax return and later need a copy, don't worry.
Rule 2 in the âApostrophesâ section says, âUse the apostrophe to show possession. Place the apostrophe before the s to show singular possession.â. Since âworldâs biggestâ is singular possessive, you need to use âs regardless of which noun follows it.
Use an apostrophe after the âsâ at the end of a plural noun to show possession. It is not necessary to add another âsâ to the end of a plural noun. If a plural noun doesnât end in âs,â add an ââsâ to create the possessive form. *Remember, a possessive noun needs an apostrophe and an âsâ at the end.
