Statements vs Receipts

[Wesley Pittman]

Hello,

I was wondering if the tax savvy may be able to direct me. In the instance of an audit is the IRS okay with year end statements instead of receipts for regularly occurring expenses such as mortgage and utilities? I've been cataloging the receipts every month but it seems a bit tedious considering I know I'm going to get a year end statement that summarizes the charges made that year.

Thanks!
