For example, if you're single, and you normally donate $10K per year to charity but have no other deductions, you will get the $12K standard deduction and the donations have no impact on your taxes. If you can save up for 3 years and donate $30K in one year instead, you'll get to deduct $30K that year, and $12K the other two years, instead of $12K every year.what is bunching of itemized deductions?
I've used Free File Fillable Forms for years, which has become less pleasant as our taxes have become more complex in recent years. This year I used FreeTaxUSA and it was so much more pleasant and easy in comparison. I'm a convert, for sure. Here's a link to their security page: https://www.freetaxusa.com/safe.jsp
I agree with mountainsoft. Even if you don't put your information out there, it's out there anyway.
