When your baby is a little older, you can start adding pumping to your daily routine. While it's not necessary, it's comforting to have a little bit of a stash of milk built up before you return to work. Warning - be sure to read this page on smart use of your freezer stash!
You must file a tax return if your net earnings from self-employment were $400 or more. So consider this: you may be 36 years old, single and make less than $10,000 per year in regular employment income, but if you have a side business that nets you more than $400, you will need to file a federal tax return.
The taxpayer can also file a refund claim for tax that he paid with the original tax return. Generally, under section 6511, the taxpayer is required to file a claim for refund within three years from the date the original return was filed or two years from the date the tax was paid, whichever is later.
