Income Taxes [Abstract]
Income Taxes	Note 4. Income Taxes Accounting Standards Codification (ASC) 740, Income Taxes, defines the threshold for recognizing the benefits of tax return positions in the financial statements as "more-likely-than-not" to be sustained by the taxing authority. As of June 30, 2014, Pinnacle Financial had no unrecognized tax benefits related to Federal or State income tax matters and does not currently anticipate any material increase or decrease in unrecognized tax benefits relative to any tax positions taken prior to June 30, 2014. As of June 30, 2014, Pinnacle Financial has accrued no interest and no penalties related to uncertain tax positions. Pinnacle Financial's effective tax rate for the three and six months ended June 30, 2014 was 33.1% and 33.2% compared to 32.8% for the three and six months ended June 30, 2013. The effective tax rate differs from the Federal income tax statutory rate of 35% and state income tax rate of 6.50% primarily due to our investments in bank qualified municipal securities, bank-owned life insurance, and tax savings from our captive insurance subsidiary, PNFP Insurance Inc., offset in part by meals and entertainment and executive compensation expense, portions of which are non-deductible.
