Retirement tax questions

To be honest, I read through the whole thread a few times, especially Jack10000's post. However, I still don't quite get it. 

 

I only purchased a few shares, and I was charged less than $1 per month for the management fee for 10 months last year. 

 

Can I just write the cost basis as $0 and the purchase date as the date when the fee is collected to make my life easier? Do I have to adjust the cost basis of the GLD shares that I sold? My hunch is that the cost basis should be lower but I couldn't care about those few dollars if any. 

 

By doing so, I think I am paying a little bit more tax, but that would save me tons of time. However, I do want to make sure that by doing so, I do pay MORE tax than needed. I don't want to own IRS a single penny 🙂

 

Please advise.
