Accounting Policies [Abstract]
Revenue Recognition, Policy [Policy Text Block]	Revenue Recognition We recognize revenue when (i) persuasive evidence of an arrangement exists, (ii) delivery of the product has occurred or a service has been provided, (iii) the price is fixed or determinable and (iv) collectability is reasonably assured. Revenues are earned from our customers primarily through the connection to our networks, digital and commercial television (TV) programming, Internet services (high-speed broadband), and hosted and managed services. Revenues for these services are billed based on set rates for monthly service or based on the amount of time the customer is utilizing our facilities. The revenue for these services is recognized when the service is rendered. Revenues earned from interexchange carriers (IXCs) accessing our network are based on the utilization of our network by these carriers as measured by minutes of use on the network or special access to the network by the individual carriers. Revenues are billed at tariffed access rates for both interstate and intrastate calls. Revenues for these services are recognized based on the period the access is provided. Interstate access rates are established by a nationwide pooling of companies known as the National Exchange Carriers Association (NECA). The Federal Communications Commission (FCC) established NECA in 1983 to develop and administer interstate access service rates, terms and conditions. Revenues are pooled and redistributed on the basis of a company's actual or average costs. There has been a change in the composition of interstate access charges in recent years, shifting more of the charges to the end user and reducing the amount of access charges paid by IXC’s. We believe this trend will continue. New Ulm Telecom’s and Sleepy Eye Telephone Company’s (SETC) settlements from the pools are based on their actual costs to provide service, while the settlements for NU Telecom subsidiaries – Western Telephone Company, Peoples Telephone Company and Hutchinson Telephone Company (HTC) are based on nationwide average schedules. Access revenues for New Ulm Telecom and SETC include an estimate of a cost study each year that is trued-up subsequent to the end of any given year. Our management believes the estimates included in our preliminary cost study are reasonable. We cannot predict the future impact that industry or regulatory changes will have on interstate access revenues. Intrastate access rates are filed with state regulatory commissions in Minnesota and Iowa. We derive revenues from the sale, installation and servicing of communication systems. In accordance with GAAP, these deliverables are accounted for separately. We recognize revenue from customer contracts for sales and installations using the completed-contract method, which recognizes income when the contract is substantially complete. We recognize rental revenues over the rental period.
Cost of Sales, Policy [Policy Text Block]	Cost of Services (excluding depreciation and amortization) Cost of services includes all costs related to delivery of communication services and products. These operating costs include all costs of performing services and providing related products including engineering, network monitoring and transport cost.
Selling, General and Administrative Expenses, Policy [Policy Text Block]	Selling, General and Administrative Expenses Selling, general and administrative expenses include direct and indirect selling expenses, customer service, billing and collections, advertising and all other general and administrative costs associated with the operations of the business.
Depreciation, Depletion, and Amortization [Policy Text Block]	Depreciation and Amortization Expense We use the group life method (mass asset accounting) to depreciate the assets of our telephone companies. Telephone plant acquired in a given year is grouped into similar categories and depreciated over the remaining estimated useful life of the group. When an asset is retired, both the asset and the accumulated depreciation associated with that asset are removed from the books. Due to rapid changes in technology, selecting the estimated economic life of telecommunications plant and equipment requires a significant amount of judgment. We periodically review data on expected utilization of new equipment, asset retirement activity and net salvage values to determine adjustments to our depreciation rates. Depreciation expense was $1,818,176 and $1,812,272 for the three months ended March 31, 2016 and 2015. We amortize our definite-lived intangible assets over their estimated useful lives. Identifiable intangible assets that are subject to amortization are evaluated for impairment.
Income Tax, Policy [Policy Text Block]	Income Taxes The provision for income taxes consists of an amount for taxes currently payable and a provision for tax consequences deferred to future periods. Deferred income taxes are recognized for the future tax consequences attributable to differences between the financial statement carrying amounts of existing assets and liabilities, and their respective tax bases. Significant components of our deferred taxes arise from differences (i) in the basis of property, plant and equipment due to the use of accelerated depreciation methods for tax purposes, as well as (ii) in partnership investments and intangible assets due to the difference between book and tax basis. Our effective income tax rate is normally higher than the United States tax rate due to state income taxes and permanent differences. We account for income taxes in accordance with GAAP. As required by GAAP, we recognize the financial statement benefit of tax positions only after determining that the relevant tax authority would more-likely-than-not sustain the position following an audit. For tax positions meeting the more-likely-than-not threshold, the amount recognized in the financial statements is the largest benefit that has a greater than 50 percent likelihood of being realized upon ultimate settlement with the relevant tax authority. As of March 31, 2016 and December 31, 2015 we had $0 of unrecognized tax benefits, which if recognized would affect the effective tax rate. We are primarily subject to United States, Minnesota, Nebraska and Iowa income taxes. Tax years subsequent to 2011 remain open to examination by federal and state tax authorities. Our policy is to recognize interest and penalties related to income tax matters as income tax expense. As of March 31, 2016 and December 31, 2015 we had no interest or penalties accrued.
New Accounting Pronouncements, Policy [Policy Text Block]	Recent Accounting Developments In February 2016, the Financial Accounting Standards Board (FASB) issued Accounting Standards Update (ASU 2016-02), “Leases,” which requires the recognition of lease assets and lease liabilities by lessees for those leases classified as operating leases under previous GAAP. This change will result in an increase to recorded assets and liabilities on lessees’ financial statements, as well as changes in the categorization of rental costs, from rent expense to interest and depreciation expense. Other effects may occur depending on the types of leases and the specific terms of them utilized by particular lessees. The ASU is effective for the Company on January 1, 2019, and early application is permitted. Modified retrospective application is required. The Company is evaluating the effect that ASU 2016-02 will have on its consolidated financial statements and related disclosures. In November 2015, FASB issued ASU 2015-17, “Income Taxes,” simplifying the balance sheet classification of deferred taxes. ASU 2015-17 requires that deferred tax liabilities and assets be classified as noncurrent in a classified statement of financial position. ASU 2015-17 removes the requirement to separate deferred income tax liabilities and assets into current and noncurrent amounts. ASU 2015-17 is effective for annual and interim periods beginning after December 15, 2016, with early adoption permitted. We expect, upon adoption of this guidance, that our current financial statement classification of deferred tax assets and liabilities will all be classified as noncurrent on our condensed consolidated balance sheet. In April 2015, FASB issued ASU 2015-03, “Interest-Imputation of Interest,” simplifying the presentation of debt issuance costs. ASU 2015-03 requires that premiums, discounts, and loan fees and costs associated with long-term debt be reflected as a reduction of the outstanding debt balance. Previous guidance had treated such loan fees and costs as a deferred charge on the balance sheet. As a result of implementing ASU 2015-03, the Company reclassified $340,275 and $355,070 of unamortized loan fees and costs included in deferred charges and other assets as of March 31, 2016 and December 31, 2015 to long-term debt. $59,178 was allocated to current maturities of long-term debt as of March 31, 2016 and December 31, 2015. $281,097 and $295,892 were allocated to long-term debt as of March 31, 2016 and December 31, 2015. Total assets, as well as total liabilities and shareholders’ equity, were also reduced by $340,275 and $355,070 as of March 31, 2016 and December 31, 2015. There was no impact on the consolidated statements of income or cash flows. In May 2014, FASB issued ASU 2014-09, “Revenue from Contracts with Customers,” and created a new topic in the FASB Accounting Standards Codification, Topic 606. ASU 2014-09 has been delayed by ASU 2015-14 to be effective for annual reporting periods beginning after December 15, 2017. The new standard provides a single comprehensive revenue recognition framework for all entities and supersedes nearly all existing United States GAAP revenue recognition guidance, including industry-specific guidance. The core principle of the revenue model is that an entity should recognize revenue in a manner that depicts the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. The standard is designed to create greater comparability for financial statement users across industries and also requires enhanced disclosures. The amendments are effective for annual reporting periods beginning after December 15, 2017, including interim periods within the reporting period. Early application is not permitted. We are currently evaluating the impact this guidance may have on our consolidated financial statements and related disclosures. We have reviewed all other significant newly issued accounting pronouncements and determined they are either not applicable to our business or that no material effect is expected on our financial position and results of operations.

In February 2016, the Financial Accounting Standards Board (FASB) issued Accounting Standards Update (ASU 2016-02), “Leases,” which requires the recognition of lease assets and lease liabilities by lessees for those leases classified as operating leases under previous GAAP. This change will result in an increase to recorded assets and liabilities on lessees’ financial statements, as well as changes in the categorization of rental costs, from rent expense to interest and depreciation expense. Other effects may occur depending on the types of leases and the specific terms of them utilized by particular lessees. The ASU is effective for the Company on January 1, 2019, and early application is permitted. Modified retrospective application is required. The Company is evaluating the effect that ASU 2016-02 will have on its consolidated financial statements and related disclosures.

In November 2015, FASB issued ASU 2015-17, “Income Taxes,” simplifying the balance sheet classification of deferred taxes. ASU 2015-17 requires that deferred tax liabilities and assets be classified as noncurrent in a classified statement of financial position. ASU 2015-17 removes the requirement to separate deferred income tax liabilities and assets into current and noncurrent amounts. ASU 2015-17 is effective for annual and interim periods beginning after December 15, 2016, with early adoption permitted. We expect, upon adoption of this guidance, that our current financial statement classification of deferred tax assets and liabilities will all be classified as noncurrent on our condensed consolidated balance sheet.

In April 2015, FASB issued ASU 2015-03, “Interest-Imputation of Interest,” simplifying the presentation of debt issuance costs. ASU 2015-03 requires that premiums, discounts, and loan fees and costs associated with long-term debt be reflected as a reduction of the outstanding debt balance. Previous guidance had treated such loan fees and costs as a deferred charge on the balance sheet. As a result of implementing ASU 2015-03, the Company reclassified $340,275 and $355,070 of unamortized loan fees and costs included in deferred charges and other assets as of March 31, 2016 and December 31, 2015 to long-term debt. $59,178 was allocated to current maturities of long-term debt as of March 31, 2016 and December 31, 2015. $281,097 and $295,892 were allocated to long-term debt as of March 31, 2016 and December 31, 2015. Total assets, as well as total liabilities and shareholders’ equity, were also reduced by $340,275 and $355,070 as of March 31, 2016 and December 31, 2015. There was no impact on the consolidated statements of income or cash flows.

In May 2014, FASB issued ASU 2014-09, “Revenue from Contracts with Customers,” and created a new topic in the FASB Accounting Standards Codification, Topic 606. ASU 2014-09 has been delayed by ASU 2015-14 to be effective for annual reporting periods beginning after December 15, 2017. The new standard provides a single comprehensive revenue recognition framework for all entities and supersedes nearly all existing United States GAAP revenue recognition guidance, including industry-specific guidance.

The standard is designed to create greater comparability for financial statement users across industries and also requires enhanced disclosures. The amendments are effective for annual reporting periods beginning after December 15, 2017, including interim periods within the reporting period. Early application is not permitted. We are currently evaluating the impact this guidance may have on our consolidated financial statements and related disclosures.

We have reviewed all other significant newly issued accounting pronouncements and determined they are either not applicable to our business or that no material effect is expected on our financial position and results of operations.
