Overview

What it is, and why it matters.

In the US, “communications services tax” usually means Florida’s Communications Services Tax (CST). It replaced sales tax and several other state and local charges on telephone, VoIP, cable and satellite services with a single tax administered by the Florida Department of Revenue. It has a state portion, made up of the state CST and a gross receipts tax, and a local portion whose rate depends on the customer’s service address.

At the time of writing, the state portion totals 7.44% (4.92% state CST plus 2.52% gross receipts tax), and local rates vary by city and county. Providers register with the Department, collect the tax from customers and file Form DR-700016 each month. Returns are due on the 1st and late after the 20th of the following month.

Outside Florida, telecom and VoIP providers face a patchwork of their own. Some states have telecom-specific taxes (Virginia, for example, has a communications sales and use tax), most states and many localities charge 911 or E911 fees, and some run state universal service funds. At federal level, providers contribute to the Universal Service Fund through FCC Form 499 filings, covered under FCC Filing.

The process

How it runs, step by step.

Timings depend on the authority and on how quickly documents come together. We tell you what’s typical for your case at the start.

Start with a conversation
  1. Product and customer review

    We look at what you sell, how it is delivered and where your customers’ service addresses are.

  2. Obligation map

    We list the taxes and fees that apply by state and locality, including Florida CST, 911 fees and USF.

    Typically 1–3 weeks, depending on the number of states

  3. Registration

    We register you with the Florida Department of Revenue and with other states where required.

    Processing times vary by state

  4. Billing set-up

    We check that your billing system or tax engine applies the right rates and sourcing.

  5. Monthly filing

    We prepare and file DR-700016 and other returns from your billing data and reconcile the amounts.

What we’ll need

The information to have ready.

A typical checklist. After the first conversation we send a version specific to your situation, so you don’t gather anything you don’t need.

Business and product details

  • A description of each service (hosted voice, SIP trunks, numbers, messaging, bundles)
  • Wholesale suppliers and resale arrangements
  • FCC Registration Number (FRN) and Form 499 Filer ID, if you have them

Billing data

  • Revenue by customer service address and by month
  • Sample invoices showing the taxes and fees currently charged
  • Billing system or tax engine reports

Existing registrations

  • Florida and other state tax account numbers
  • Prior returns and any notices

Please don’t email passports or bank statements. Once we’ve spoken, you’ll get access to a secure upload.

Common mistakes

Where this usually goes wrong.

The problems we are most often asked to fix, and what they tend to cost.

  • Mistake 01

    Charging Florida sales tax instead of CST

    Communications services sold in Florida are generally taxed under the CST rather than the ordinary sales tax. Charging sales tax usually means collecting and filing under the wrong regime.

  • Mistake 02

    Assigning local tax to the wrong jurisdiction

    Local CST follows the customer’s service address. Relying on ZIP codes alone can place customers in the wrong city or county, leading to underpayment or overcharging.

  • Mistake 03

    Treating a bundle as a single product

    When taxable and non-taxable services are sold together, the whole charge can become taxable unless the non-taxable part is separately identified in the way the state requires.

  • Mistake 04

    Keeping tax and USF data in separate silos

    Revenue reported to the Florida Department of Revenue, state 911 authorities and USAC should reconcile. Inconsistencies commonly prompt questions from any of them.

Worth knowing

The limits, stated upfront.

  • Whether a service is taxable can depend on its technical and legal classification. We do not give legal advice on regulatory status, and complex classification questions may need telecom counsel.

  • Rates and local jurisdiction assignments change. We use the Department’s current published rates for each filing.

  • State and local 911 fees and utility users taxes vary widely; the states and localities covered are agreed at scoping.

  • We are not affiliated with the Florida Department of Revenue, USAC or the FCC.

Questions

Communication Services Tax: frequently asked.

If yours isn’t here, ask us directly. We’ll answer in plain terms.

Ask a question

Is communications services tax a federal tax?

No. The term usually refers to Florida’s Communications Services Tax, a state and local tax administered by the Florida Department of Revenue. At federal level, telecom and VoIP providers instead contribute to the Universal Service Fund through FCC Form 499 filings.

Does Florida’s CST apply to VoIP?

Generally, yes. Florida’s definition of communications services is broad and covers voice-over-internet services as well as traditional telephone, cable and satellite services, while internet access itself is not taxed. Particular products can be treated differently, so we review each one.

What is the current Florida CST rate?

At the time of writing, the state portion is 7.44% (the 4.92% state CST plus 2.52% gross receipts tax), and each local jurisdiction adds its own rate. Direct-to-home satellite service is taxed differently. We use the Department’s current published rates for each return.

When is the Florida CST return due?

Form DR-700016 is filed monthly. Returns are due on the 1st and late after the 20th of the month following the reporting period, and the date moves to the next business day when the 20th falls on a weekend or holiday.

What other taxes and fees should a VoIP provider expect?

Common charges include state and local 911 or E911 fees, state universal service fund surcharges, telecommunications relay service fees, some state telecom excise or gross receipts taxes, and federal USF contributions. Which ones apply depends on the states you serve and how your service is classified.

We only sell wholesale. Do we collect CST?

Sales for resale are generally not taxed, provided you hold the documentation Florida requires, such as a valid resale certificate from your customer. The retail provider then collects from end users.
