RFID Frequently Asked Question. What's the difference between read-only and read-write RFID tags? Microchips in RFID tags can be read-write, read-only or âwrite once, read manyâ (WORM). With read-write chips, you can add information to the tag or write over existing information when the tag is within range of a reader. Read-write tags usually have a serial number that can't be written over.
Itâs sort of complicated, but basically, if you are a dependent who is under 65 who has unearned income (i.e. interest income) over $1,050, or earned income (i.e. wages) over $6,300, or if your combined earned and unearned income exceeds $6,300, then you need to file.
Qualifying widows and widowers have to file when gross income tops $16,750 or $18,000 at 65. If you worked and had taxes withheld from your pay, you'll likely want to file even if you didn't make enough to make it mandatory. This is because you may be due a refund of the income taxes you've paid.
