Accounting Policies [Abstract]
Basis of Presentation	Note 1.	Basis of Presentation
	These interim consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States of America (“GAAP”). However, these financial statements do not include all of the information and footnotes required by GAAP for complete financial statements. The interim consolidated financial statements are unaudited and reflect all adjustments and reclassifications, which, in the opinion of management, are necessary for a fair presentation of the results of operations and financial condition as of and for the interim periods presented. All adjustments and reclassifications are of a normal and recurring nature. Results for the period ended March 31, 2015 are not necessarily indicative of the results that may be expected for any other interim periods or for the year as a whole.
	The interim consolidated financial statements of Citizens Holding Company include the accounts of its wholly-owned subsidiary, The Citizens Bank of Philadelphia (the “Bank” and collectively with Citizens Holding Company, the “Corporation”). All significant intercompany transactions have been eliminated in consolidation.
	For further information and significant accounting policies of the Corporation, see the Notes to Consolidated Financial Statements of Citizens Holding Company included in the Corporation’s Annual Report on Form 10-K for the year ended December 31, 2014, filed with the Securities and Exchange Commission on March 13, 2015.

Commitments and Contingencies Disclosure [Abstract]
Commitments and Contingent Liabilities	Note 2.	Commitments and Contingent Liabilities
	In the ordinary course of business, the Corporation enters into commitments to extend credit to its customers. The unused portion of these commitments is not reflected in the accompanying financial statements. As of March 31, 2015, the Corporation had entered into loan commitments with certain customers with an aggregate unused balance of $45,660,580 compared to an aggregate unused balance of $50,242,705 at December 31, 2014. There was $2,664,480 of letters of credit outstanding at March 31, 2015 and $2,855,480 at December 31, 2014. The fair value of such contracts is not considered material because letters of credit and loan commitments often are not used in their entirety, if at all, before they expire. The balances of such letters and commitments should not be used to project actual future liquidity requirements. However, the Corporation does incorporate expectations about the level of draws under its credit-related commitments into its asset and liability management program.
	The Corporation is a party to lawsuits and other claims that arise in the ordinary course of business, all of which are being vigorously contested. In the regular course of business, management evaluates estimated losses or costs related to litigation, and provisions are made for anticipated losses whenever management believes that such losses are probable and can be reasonably estimated. At the present time, management believes, based on the advice of legal counsel, that the final resolution of pending legal proceedings will not likely have a material impact on the Corporation’s consolidated financial condition or results of operations.

Equity Compensation Plans	Note 4.	Equity Compensation Plans
	Prior to the adoption of the 2013 Plan, as defined below, the Corporation utilized two stock-based compensation plans, the 1999 Directors’ Stock Compensation Plan (the “Directors’ Plan”) for directors, and prior to its expiration, the 1999 Employees’ Long-Term Incentive Plan (the “Employees’ Plan”) for employees.
	The following table is a summary of the stock option activity for the three months ended March 31, 2015.
			Directors’ Plan				Employees’ Plan					2013 Plan
					Weighted					Weighted				Weighted

	The intrinsic value of options granted under the Directors’ Plan at March 31, 2015, was $3,840, the intrinsic value of options granted under the Employees’ Plan at March 31, 2015, was $480, and since there were no options granted under the 2013 Plan, the intrinsic value for the 2013 Plan is $0 for a total intrinsic value at March 31, 2015, of $4,320.
	The Corporation has adopted the 2013 Incentive Compensation Plan (the “2013 Plan”), which the Corporation intends to use for all future equity grants to employees, directors or consultants until the termination or expiration of the 2013 Plan. During the quarter ended March 31, 2014, the Corporation’s directors received restricted stock grants totaling 7,500 shares of common stock. These grants vested over a one-year period ending March 13, 2015 during which time the recipients had rights to vote the shares and to receive dividends. The grant date fair value of these shares was $138,000 and was recognized over the one year restriction period at a cost of $11,500 per month less deferred taxes of $4,290 per month.

Income Taxes	3 Months Ended

Income Tax Disclosure [Abstract]
Income Taxes	Note 5.	Income Taxes
	The income tax topic of the Accounting Standards Codification (“ASC”) 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. This topic also provides guidance on the derecognition, measurement and classification of income tax uncertainties, along with any related interest and penalties, and includes guidance concerning accounting for income tax uncertainties in interim periods. As of March 31, 2015, the Corporation had no unrecognized tax benefits related to federal and state income tax matters. Therefore, the Corporation does not anticipate any material increase or decrease in the effective tax rate during 2015 relative to any tax positions taken. It is the Corporation’s policy to recognize interest or penalties related to income tax matters in income tax expense.
	The Corporation files a consolidated United States federal income tax return. The Corporation is currently open to audit under the statute of limitations by the Internal Revenue Service for all tax years after 2011. The Corporation’s consolidated state income tax returns are also open to audit under the statute of limitations for the same period.

	During the quarter ended June 30, 2014, the Corporation transferred securities with an amortized cost of $222,322,423 from available-for-sale to held-to-maturity. This transfer was completed after consideration of the Corporation’s ability and intent to hold these securities to maturity.
	The fair value of the securities transferred as of the date of transfer was $205,260,985 with a net unrealized loss of $17,061,438. In accordance with ASC 320-10-35-16, the discount on each security that resulted from this transfer is amortized over the remaining lives of the individual securities. Any unrealized holding losses on the date of the transfer are not recognized in net income but remain in accumulated other comprehensive loss. In accordance with ASC 320-10-15-10d, the unrealized loss amounts in accumulated other comprehensive loss are amortized simultaneously against interest income as the discount is accreted on the transferred securities. There is no effect on net income as the discount accretion offsets the accumulated other comprehensive loss amortization.
	The amortized cost and estimated fair value of securities held-to-maturity and the corresponding amounts of gross unrecognized gains and losses were as follows:

The Company’s unrealized losses on its Obligations of United States Government agencies, Mortgage backed securities and State, County and Municipal bonds are the result of an upward trend in interest rates, mainly in the mid-term sector. None of the unrealized losses disclosed in the previous table are related to credit deterioration. The Company has determined that none of the securities in this classification are other-than-temporarily impaired at March 31, 2015 or at December 31, 2014.
The Company’s unrealized loss on other investments relates to an investment in a pooled trust preferred security. The decline in value of the pooled trust preferred security is related to the deterioration of the markets for these types of securities brought about by the lowered credit ratings and past deferrals and defaults of the underlying issuing financial institutions. The Company owns a senior tranche of this security and therefore has a higher degree of which future deferrals and defaults would be required before the cash flow for the Company’s tranche is negatively impacted. The Company does not intend to sell this security and it is not more likely than not that the Company will be required to sell at a price less than amortized cost prior to maturity. Given these factors, the Company does not consider the investment to be other-than-temporarily impaired at March 31, 2015 or December 31, 2014.

	Loans are considered to be past due if the required principal and interest payments have not been received as of the date such payments were due. Loans are placed on non-accrual status, when, in management’s opinion, the borrower may be unable to meet payment obligations as they become due, as well as when required by regulatory provisions. Loans may be placed on non-accrual status regardless of whether such loans are considered past due. When interest accruals are discontinued, all unpaid accrued interest is reversed. Interest income is subsequently recognized only to the extent cash payments are received in excess of principal due. Loans are returned to accrual status when all the principal and interest amounts contractually due are brought current and future payments are reasonably assured.

Loans are considered impaired when, based on current information and events, it is probable the Corporation will be unable to collect all amounts due in accordance with the original contractual terms of the loan agreement, including scheduled principal and interest payments. In determining which loans to evaluate for impairment, management looks at past due loans, bankruptcy filings and any situation that might lend itself to cause a borrower to be unable to repay the loan according to the original agreement terms. If a loan is determined to be impaired and the collateral is deemed to be insufficient to fully repay the loan, a specific reserve will be established. Interest payments on impaired loans are typically applied to principal unless collectability of the principal amount is reasonably assured, in which case interest is recognized on a cash basis. Impaired loans or portions thereof, are charged-off when deemed uncollectible.
Impaired loans (in thousands) as of March 31, 2015 and December 31, 2014, segregated by class, are as follows:

The allocated allowance for loan losses attributable to restructured loans was $174,274 at March 31, 2015 and December 31, 2014. The Corporation had no remaining availability under commitments to lend additional funds on these troubled debt restructuring as of March 31, 2015.
The Corporation utilizes a risk grading matrix to assign a risk grade to each of its loans when originated and is updated as factors related to the strength of the loan changes. Loans are graded on a scale of 1 to 9. A description of the general characteristics of the 9 risk grades is as follows.
Grade 1. MINIMAL RISK - These loans are without loss exposure to the Corporation. This classification is reserved for only the best, well secured loans to borrowers with significant capital strength, low leverage, stable earnings and growth and other readily available financing alternatives. This type of loan would also include loans secured by a program of the government.
Grade 2. MODEST RISK - These loans include borrowers with solid credit quality and moderate risk of loss. These loans may be fully secured by certificates of deposit with another reputable financial institution, or secured by readily marketable securities with acceptable margins.
Grade 3. AVERAGE RISK - This is the rating assigned to the majority of the loans held by the Corporation. This includes loans with average loss exposure and average overall quality. These loans should liquidate through possessing adequate collateral and adequate earnings of the borrower. In addition, these loans are properly documented and are in accordance with all aspects of the current loan policy.
Grade 4. ACCEPTABLE RISK - Borrower generates sufficient cash flow to fund debt service but most working asset and capital expansion needs are provided from external sources. Profitability and key balance sheet ratios are usually close to peers but one or more may be higher than peers.
Grade 5. MANAGEMENT ATTENTION - Borrower has significant weaknesses resulting from performance trends or management concerns. The financial condition of the borrower has taken a negative turn and may be temporarily strained. Cash flow is weak but cash reserves remain adequate to meet debt service. Management weakness is evident.
Grade 6. OTHER LOANS ESPECIALLY MENTIONED (OLEM) - Loans in this category are fundamentally sound but possess some weaknesses. OLEM loans have potential weaknesses which may, if not checked or corrected, weaken the asset or inadequately protect the bank’s credit position at some future date. These loans have an identifiable weakness in credit, collateral, or repayment ability but there is no expectation of loss.
Grade 7. SUBSTANDARD ASSETS - Assets classified as substandard are inadequately protected by the current net worth and paying capacity of the obligor or of the collateral pledged, if any. Assets classified as substandard must have a well-defined weakness based upon objective evidence. Assets classified as substandard are characterized by the distinct possibility that the insured institution will sustain some loss if the deficiencies are not corrected. The possibility that liquidation would not be timely requires a substandard classification even if there is little likelihood of total loss.
Grade 8. DOUBTFUL - A loan classified as doubtful has all the weaknesses of a substandard classification and the added characteristic that the weakness makes collection or liquidation in full, on the basis of currently existing facts, conditions, and values, highly questionable or improbable. The possibility of loss is extremely high, but because of certain important and reasonable specific pending factors which may work to the advantage and strengthening of the asset, its classification as an estimated loss is deferred until its more exact status may be determined. A doubtful classification could reflect the fact that the primary source of repayment is gone and serious doubt exists as to the quality of a secondary source of repayment.
Grade 9. LOSS - Loans classified loss are considered uncollectible and of such little value that their continuance as bankable assets is not warranted. This classification does not mean that the asset has absolutely no recovery or salvage value, but rather it is not practical or desirable to defer writing off this basically worthless asset even though partial recovery may occur in the future. Also included in this classification is the defined loss portion of loans rated substandard assets and doubtful assets.
These internally assigned grades are updated on a continual basis throughout the course of the year and represent management’s most updated judgment regarding grades at March 31, 2015.

The allowance for loan losses is a reserve established through a provision for loan losses charged to expense, which represents management’s best estimate of probable losses within the existing portfolio of loans. The allowance, in the judgment of management, is necessary to reserve for estimated loan losses and risks inherent in the loan portfolio.
The allowance on the majority of the loan portfolio is calculated using a historical chargeoff percentage applied to the current loan balances by loan segment. This historical period is the average of the previous twenty quarters with the most current quarters weighted more heavily to show the effect of the most recent chargeoff activity. This percentage is also adjusted for economic factors such as local unemployment and general business conditions, both local and nationwide.
The group of loans that are considered to be impaired are individually evaluated for possible loss and a specific reserve is established to cover any loss contingency. Loans that are determined to be a loss with no benefit of remaining in the portfolio are charged off to the allowance. These specific reserves are reviewed periodically for continued impairment and adequacy of the specific reserve and adjusted when necessary.

Fair Value Disclosures [Abstract]
Fair Value of Financial Instruments	Note 8.	Fair Value of Financial Instruments
	The fair value topic of the ASC establishes a framework for measuring fair value and requires enhanced disclosures about fair value measurements. This topic clarifies that fair value is an exit price, representing the amount that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants. This topic also requires disclosure about how fair value was determined for assets and liabilities and establishes a hierarchy for which these assets and liabilities must be grouped, based on significant levels of inputs as follows:
	Level 1		Quoted prices in active markets for identical assets or liabilities;
	Level 2		Quoted prices in active markets for similar assets and liabilities and inputs that are observable for the asset or liability; or
	Level 3		Unobservable inputs, such as discounted cash flow models or valuations.
	The determination of where assets and liabilities fall within this hierarchy is based upon the lowest level of input that is significant to the fair value measurement.
	The following table presents assets and liabilities that are measured at fair value on a recurring basis as of March 31, 2015:

	Impaired loans with a carrying value of $11,021,776 and $10,243,082 had an allocated allowance for loan losses of $2,030,196 and $2,024,754 at March 31, 2015 and December 31, 2014, respectively. The allocated allowance is based on the carrying value of the impaired loan and the fair value of the underlying collateral less estimated costs to sell.
	Other real estate owned (“OREO”) acquired during the three-month period ended March 31, 2015, and recorded at fair value, less costs to sell, was $87,560, none of which was acquired and sold during this period. There were no writedowns during the period on properties owned. OREO acquired during 2014 and recorded at fair value, less costs to sell, was $2,874,173. Additional writedowns during 2014 on OREO acquired in previous years was $694,207.
The financial instruments topic of the ASC requires disclosure of financial instruments’ fair values, as well as the methodology and significant assumptions used in estimating fair values. In cases where quoted market prices are not available, fair values are based on estimates using present value or other valuation techniques. Those techniques are significantly affected by the assumptions used, including the discount rate and estimates of future cash flows. In that regard, the derived fair value estimates cannot be substantiated by comparison to independent markets and, in many cases, could not be realized in immediate settlement of the instrument. The financial instruments topic of the ASC excludes certain financial instruments from its disclosure requirements. Accordingly, the aggregate fair value amounts presented do not represent the underlying value of the Corporation and may not be indicative of amounts that might ultimately be realized upon disposition or settlement of those assets and liabilities.

The fair value estimates, methods and assumptions used by the Corporation in estimating its fair value disclosures for financial statements were as follows:
Cash and Due from Banks and Interest Bearing Deposits with Banks
The carrying amounts reported in the balance sheet for these instruments approximate fair value because of their immediate and shorter-term maturities, which are considered to be three months or less when purchased.
Securities Held-to-Maturity
Securities held-to-maturity consists of debt securities such as obligations of states and other political subdivisions. Where quoted market prices in active markets are available, securities are classified within Level 1 of the fair value hierarchy. If quoted prices from active markets are not available, fair values are based on quoted market prices for similar instruments traded in active markets, quoted market prices for identical or similar instruments traded in markets that are not active, or model-based valuation techniques where all significant assumptions are observable in the market. Such instruments are classified within Level 2 of the fair value hierarchy. When assumptions used in model-based valuation techniques are not observable in the market, the assumptions used by management reflect estimates of assumptions used by other market participants in determining fair value. When there is limited transparency around the inputs to the valuation, the instruments are classified within Level 3 of the fair value hierarchy.
Securities Available-for-Sale
Fair values for investment securities are based on quoted market prices, when available (Level 1). If quoted market prices are not available, fair values are based on quoted market prices of comparable instruments (Level 2). When neither quoted prices nor comparable instruments are available, unobservable inputs are needed to form an expected future cash flow analysis to establish fair values (Level 3).
The Corporation owns certain beneficial interests in one collateralized debt obligation secured by community bank trust preferred securities. These interests do not trade in a liquid market, and therefore, market quotes are not a reliable indicator of their ultimate realizability. The Corporation utilizes a discounted cash flow model using inputs of (1) market yields of trust-preferred securities as the discount rate and (2) expected cash flows which are estimated using assumptions related to defaults, deferrals and prepayments to determine the fair values of these beneficial interests. Many of the factors that adjust the timing and extent of cash flows are based on judgment and not directly observable in the markets. Therefore, these fair values are classified as Level 3 valuations for accounting and disclosure purposes. Since observable transactions in these securities are extremely rare, the Corporation uses assumptions that a market participant would use in valuing these instruments. These assumptions primarily include cash flow estimates and market discount rates. The cash flow estimates are sensitive to the assumptions related to the ability of the issuers to pay the underlying trust preferred securities according to their terms. The market discount rates depend on transactions, which are rare given the lack of interest of investors in these types of beneficial interests.
Net Loans
For variable-rate loans that reprice frequently and with no significant change in credit risk, fair values are based on carrying values. The fair values for other loans (i.e., commercial real estate and rental property mortgage loans, commercial and industrial loans, financial institution loans, and agricultural loans) are estimated using discounted cash flow analyses, using interest rates currently being offered for loans with similar terms to borrowers of similar credit quality.
Deposits
The fair values for demand deposits, NOW and money market accounts and savings accounts are, by definition, equal to the amount payable on demand at the reporting date (i.e., their carrying amounts). The carrying amounts for variable-rate, fixed-term money market accounts and time deposits approximate their fair values at the reporting date. Fair values for fixed-rate time deposits are estimated using a discounted cash flow calculation that applies interest rates currently being offered on certificates to a schedule of aggregated expected monthly maturities on time deposits.
Federal Home Loan Bank (FHLB) Borrowings
The fair value of FHLB advances is based on a discounted cash flow analysis.
Securities Sold Under Agreement to Repurchase
Due to the short term nature of these instruments, which is generally three months or less, the carrying amount is equal to the fair value.
Off-Balance Sheet Instruments
The fair value of commitments to extend credit and letters of credit are estimated using fees currently charged to enter into similar agreements. The fees associated with these financial instruments are not material.
