After you file

Thanks for your reply.

I'm trying to fill form 8606 starting from 2015.

For 2015, line 2 (total basis in traditional IRAs) will be zero (0) since that is my first year of nondeductible contribution,and conversion to Roth IRA. I'm also below 50 years

Then for 2016,line 2 will be $5500,

Then for 2017,line 2 will be $11000,

Then for 2018 line 2 will be $16500,

Then for 2019 line 2 should be $22000.

Am I correct?

If I'm not correct, can you tell me what line 2 should be in each year starting from 2015.

I maxed my contribution in each year,and line 2 seems to be the line I don't understand in form 8606.

Thanks in advance for your reply
