Commercial Broadcasting (Tax) (Individual Transmitter Amounts) Determination 2017

The determination builds on several defined terms that are central to the calculation. The uncapped individual transmitter amount is the gross figure before any cap from the Act is applied. For most transmitters, this is calculated by multiplying a rate per kHz of spectrum bandwidth by the spectrum bandwidth assigned to the transmitter's band, then multiplying by a maximum power factor, and then if that result is less than the minimum uncapped amount, using the minimum instead. The minimum uncapped individual transmitter amount acts as a floor; for 2017-18 it is $39.57 (subsection 6(3)), and for later years it is indexed by a formula using the indexation factor from the Act (subsection 6(4)).

Dollars per kHz of spectrum bandwidth is a critical variable. It is defined in a table for 2017-18 (subsection 6(5)) that cross references population density with the band in which the transmitter operates: AM, FM, VHF, or UHF. For 2017-18, low density locations attract $0.2079 per kHz across all bands, medium density attracts $9.2741 per kHz for AM/FM and $13.1579 for VHF/UHF, and high density attracts $20.2667 for AM/FM and $26.6588 for VHF/UHF. These figures are then indexed each financial year using the same indexation factor applied to the minimum uncapped amount (subsection 6(6)). The indexation factor is defined in the Act, not in this instrument, but the determination references it.

Spectrum bandwidth is fixed per band (subsection 6(7)): 18 kHz for AM, 200 kHz for FM, 7,000 kHz for VHF, and 7,000 kHz for UHF. The maximum power factor depends on the transmitter's maximum power categorisation: low power yields 0.1, medium yields 1.0, and high yields 10.0 (subsection 6(8)). The combination of a high density, VHF or UHF band, and high power yields the highest uncapped amount, while low density and low power yield a result at or near the minimum.

Population density is defined in section 5 via a table. High density applies to locations in the Sydney, Melbourne, or Brisbane areas. Medium density applies to the Perth, Adelaide, or Newcastle areas. Low density applies to areas not already covered but within the East Australia low density area, Western Australia low density area, Tasmania low density area, or Darwin low density area. A location is remote if none of those categories apply. These area definitions are incorporated by reference from Part 1 of Schedule 1 to the Radiocommunications (Transmitter Licence Tax) Determination 2015 as in force on 1 July 2017 (subsection 5(3)). This means that the precise boundaries of these density zones are not within the instrument itself; a broadcaster must consult that separate determination to determine which area a particular location falls into.

The concept of an alternative transmitter is also important. It is defined in section 4 as a transmitter covered by a licence that is authorised to operate only when another transmitter authorised under that same licence is not operating. This covers backup or standby transmitters that are not intended to be used simultaneously with the primary transmitter. The effect is that such transmitters attract only the minimum uncapped amount, regardless of their power or location. That lower tax treatment recognises that they are not adding extra spectrum occupancy concurrent with the primary transmitter.

The adjustment mechanism in section 7 introduces the concept of a daily amount. This is the uncapped amount for a transmitter at the start of a day (disregarding the section 7 adjustment itself) divided by the number of days in the financial year. The method statement then aggregates those daily amounts over the previous tax period (between anniversaries) and compares them to the uncapped amount at the start of that period. The difference is used to increase or decrease the uncapped amount at the current anniversary. Notably, for this daily calculation, indexation that occurs after the start of the previous tax period is disregarded (subsection 7(3)); instead, each day is treated as if it fell in the financial year in which the previous tax period started. This prevents the indexation from skewing the proration.

The determination directly affects all commercial broadcasting licensees who hold transmitter licences under the Broadcasting Services Act 1992 and the Radiocommunications Act 1992. These are the entities that must pay the annual tax calculated using the individual transmitter amounts. The determination does not affect non commercial broadcasters, such as national broadcasters (ABC and SBS) or community broadcasters, because the tax is imposed only on commercial broadcasting transmitter licences.

Within the commercial broadcasting sector, the impact varies significantly by location and transmitter characteristics. Broadcasters serving major metropolitan areas (Sydney, Melbourne, Brisbane) face the highest dollars per kHz rates, especially for VHF or UHF transmitters. A high power VHF transmitter in Sydney, for example, would have a very large uncapped amount. By contrast, a broadcaster operating a low power AM transmitter in a remote location would pay only the minimum uncapped amount, currently $39.57 plus indexation. Regional broadcasters in low density areas (such as parts of South Australia, Western Australia, Tasmania, and the Northern Territory, but excluding the defined city areas) would pay a much lower rate per kHz than their metropolitan counterparts. However, even within low density areas, a high power VHF transmitter would still generate a significant uncapped amount due to the large spectrum bandwidth (7,000 kHz) and the maximum power factor of 10.

The determination also affects broadcasters who operate alternative transmitters. These are typically backup transmitters that switch in when a main transmitter fails. They are treated favourably, attracting only the minimum uncapped amount. This reduces the incentive to operate multiple redundant transmitters jointly, but also means that a licensee with a single primary transmitter and a backup does not face a doubled tax burden so long as the backup is truly an alternative transmitter as defined.

Broadcasters holding multiple transmitter licences across different locations will have to calculate the individual transmitter amount for each transmitter separately, because the amount is per transmitter, not per licence. The determination does not aggregate amounts across transmitters; each transmitter on a licence has its own amount, and the total tax for that licence is the sum of the individual amounts for all transmitters covered by the licence, subject to the cap under the Act. This means that a licence covering multiple transmitters at different locations and with different bands will require a separate calculation for each transmitter, taking into account each one's location, band, and power.

Indirectly, the determination affects potential new entrants into commercial broadcasting. The tax burden, though comparatively small in the context of a major television or radio operation, adds to the fixed costs of operating a transmitter. The indexation provisions mean that real costs increase over time, though the individual transmitter amount cap in the Act may limit the maximum liability for any single transmitter. The lower amounts for remote and low density areas may slightly favour regional broadcasters relative to metropolitan ones, but the tax itself is only one component of regulatory costs.

The determination itself does not create duties or rights; it is a subordinate instrument that supplies numerical values used by the Act. The operative duties arise under the Commercial Broadcasting (Tax) Act 2017. That Act imposes a tax on commercial broadcasting transmitter licences, and the amount of tax for each transmitter is the individual transmitter amount determined by this instrument (subject to the cap). The broadcaster's primary duty is to pay the tax by the due date. The Act provides for the tax to be payable annually on the anniversary of the licence commencement date, or on such other date as the Act specifies.

Broadcasters have a right under this instrument to have the uncapped individual transmitter amount calculated in accordance with the formulas, including the right to have adjustments made under section 7 when the licence is varied during the year. The adjustment mechanism ensures that if a broadcaster reduces the power of a transmitter, or moves it to a lower density location, the tax liability for the next anniversary is reduced to reflect the period when the lower characteristics applied. Conversely, if the broadcaster upgrades power or moves to a higher density area, the adjustment increases the future tax. This prevents the broadcaster from being permanently locked into a high rate based on a brief mid-year variation.

The determination also implicitly confers a right to rely on the minimum uncapped amount for remote locations and alternative transmitters. A broadcaster that can demonstrate that a transmitter is at a remote location within the meaning of section 5, or is an alternative transmitter as defined, is entitled to the minimum uncapped amount regardless of the transmitter's power or band. This right is absolute; the determination does not impose any further conditions beyond meeting the definition.

There is no right under this instrument to dispute the population density classification; the classification is determined by the physical location of the transmitter under the licence and the external reference instrument. If a broadcaster believes the location falls within a particular density category but the Australian Communications and Media Authority has a different view, the dispute would be over the meaning of the Radiocommunications (Transmitter Licence Tax) Determination 2015 definitions.

The determination also gives broadcasters the right to have the uncapped amount recalculated when a transmitter is added to a licence during the tax period. Under subsection 7(4), for days before the transmitter was added, the uncapped amount is taken to be nil. This prevents the broadcaster from being charged for a full year's tax on a transmitter that was only added part way through the period.

The determination does not contain any penalty provisions. Penalties for non payment or underpayment of the tax would be found in the Commercial Broadcasting (Tax) Act 2017, the Taxation Administration Act 1953, or the Regulatory Powers (Standard Provisions) Act 2014. The instrument is purely a calculational tool. However, if a broadcaster uses the wrong numbers in calculating the tax, the underpaid amount would be recoverable as a tax debt. There may also be administrative penalties for late payment or false statements, though those are not within the scope of this determination.

The Act itself (not reproduced in the source) would define the due date, the method of payment, and any late payment penalty. The determination, being a legislative instrument, is enforceable as law. A broadcaster who fails to apply the correct population density, band, power factor, or indexation could be liable for a shortfall. Conversely, overpayment could be recoverable, but the determination does not provide a refund mechanism.

The determination contains no monitoring or audit provisions. Enforcement is likely to be carried out by the Australian Communications and Media Authority, which administers the licences, or by the Australian Taxation Office if the tax is collected as a tax. The complexity of the formulas, especially the section 7 adjustment, creates a compliance burden that could lead to inadvertent errors. A broadcaster that miscalculates the daily amounts or misapplies the indexation disregard in step 1 might end up with an incorrect liability.

The determination is made under the Commercial Broadcasting (Tax) Act 2017 and is expressly for the purposes of paragraph 8(1)(a) of that Act. That paragraph requires the individual transmitter amount for a transmitter to be determined by a legislative instrument made by the Minister. So the determination is an integral part of the tax calculation under the Act.

The definition of population density areas in section 5 incorporates by reference the Radiocommunications (Transmitter Licence Tax) Determination 2015 as in force on 1 July 2017. That instrument defines areas such as the Sydney area, Melbourne area, etc., using technical descriptions of licence areas. This cross reference means that any changes to the Radiocommunications determination after 1 July 2017 do not affect the population density classification under this determination; the definitions are locked as at that date. This creates stability but could lead to divergence if the underlying areas are later redefined for other regulatory purposes.

The determination also interacts with the Radiocommunications Act 1992 and the Broadcasting Services Act 1992 through the transmitter licence regime. The transmitter licence itself is issued under the Radiocommunications Act, and the licence details (location, band, power) are used in the calculation under this determination. The condition of being an alternative transmitter is likely to be recorded on the licence.

The indexation factor is defined in the Act, not in the determination. The determination uses that factor to update the minimum uncapped amount and the dollars per kHz each financial year. The indexation factor is presumably linked to a consumer price index or similar measure, so the determination ties the tax burden to inflation, absent a legislative override.

The determination does not interact with state or territory laws directly, as the tax and spectrum management are Commonwealth matters. However, the geographic definitions of areas (such as Newcastle area) may relate to geographic boundaries used in other Commonwealth instruments.

The source document is the original determination made on 17 October 2017, commencing on 1 July 2017. It includes a commencement table that shows the whole instrument commenced on 1 July 2017. The note to the commencement table states that the table relates only to the provisions as originally made and will not be amended to deal with any later amendments. No amendment history is recorded in the source. It is possible that the instrument has been amended since 2017, but the source does not reflect any such amendments. The determination was made by the Minister for Communications, Mitch Fifield, and is a legislative instrument registered on the Federal Register of Legislation. Any amendment would typically be done by a subsequent determination amending or replacing this one.

The source document contains no reference to any litigation. No cases are cited in the determination or in the explanatory materials provided. It is not possible from this source alone to determine whether the determination has been challenged in court or in the Administrative Appeals Tribunal. Given that the determination sets tax amounts based on objective criteria and incorporates indexed figures, the grounds for challenge would be limited to errors in the formula, jurisdictional issues, or the Minister failing to consider relevant matters. No such challenges are evident from the source.

Several aspects of the determination could trip up a practitioner or compliance officer.

First, the determination incorporates the Radiocommunications (Transmitter Licence Tax) Determination 2015 to define geographic density areas. That instrument is not reproduced in this determination. A broadcaster must obtain that separate determination to identify whether a location falls in the Sydney area, Melbourne area, etc. The density area definitions refer to the Radiocommunications determination as in force on 1 July 2017, so any later amendments to that determination are irrelevant. However, the broadcaster must still locate the correct version of that determination, which as of 1 July 2017 is a specific snapshot. Using a later version could produce the wrong density classification.

Second, the indexation formulas in subsections 6(4) and 6(6) appear straightforward but require careful application. The formula for the minimum uncapped amount in a later financial year is: previous minimum uncapped amount multiplied by the indexation factor. The dollars per kHz formula is similar: previous dollars per kHz multiplied by the indexation factor. The indexation factor is defined in the Act, but the determination does not list the actual factor for any year. The broadcaster must look to the Act to find the current factor. That factor may change each year. The rounding rule for the minimum uncapped amount is not specified in the determination; subsection 6(2) rounds the uncapped amount to the nearest dollar, but the minimum uncapped amount itself is the starting point. The dollars per kHz figures for 2017-18 are given as decimal numbers with four significant figures; after indexation they may produce many decimal places, and the determination does not explicitly say to round them before multiplying by bandwidth and power factor. Prudent practice would be to keep full precision until the final rounding step.

Third, the maximum power factor table (subsection 6(8)) uses only three categories: low (0.1), medium (1.0), and high (10.0). The determination does not define what maximum power corresponds to each category. It says "if the maximum power of the transmitter is low", etc. But "low" is not independently defined. The maximum power would be specified in the transmitter licence under the Radiocommunications Act. A broadcaster must interpret the licence condition to decide whether the power is low, medium, or high. The determination provides no numerical thresholds. This could lead to inconsistent classification, especially for transmitters with power levels near the boundary between low and medium or medium and high. The external Radiocommunications determination may have definitions for power classes, but this instrument does not incorporate them.

Fourth, the alternative transmitter definition requires that the transmitter is authorised to operate only when another transmitter authorised under the same licence is not in operation. If a transmitter can operate simultaneously with the other transmitter (for example, during a simulcast or test period), it is not an alternative transmitter. Broadcasters may inadvertently treat two transmitters as alternatives when they technically allow simultaneous operation, which would lead to underpayment. Conversely, a backup transmitter that is genuinely only used when the main transmitter fails should qualify.

Fifth, the section 7 adjustment is complex and easy to misapply. The method statement requires calculating daily amounts for each day in the previous tax period, using the uncapped amount at the start of that day (disregarding section 7). But for days when the transmitter was not yet covered by the licence (because it was added later), the uncapped amount is taken to be nil (subsection 7(4)). The example in subsection 7(2) illustrates a scenario where a high power UHF transmitter in a medium density location is later changed to medium power. The example shows the calculation, but it assumes no indexation on 1 July 2018 for simplicity. In reality, indexation might apply on 1 July of that financial year, and the daily amount would need to be calculated using the uncapped amount for each day, which may change on 1 July due to indexation. However, subsection 7(3) provides that for the purposes of step 1, each day in the previous tax period is taken to have occurred in the financial year in which the previous tax period started. This means indexation that occurs between the start of the previous tax period and the current anniversary is disregarded; the daily amounts are calculated using the rates applicable at the start of that period. The example does not illustrate this nuance, but it is critical. A broadcaster who uses current indexed rates for days after 1 July would overstate or understate the daily amounts.

Sixth, the determination uses the phrase "financial year beginning on 1 July 2017" for the initial amounts. For later financial years, the formulas reference "the previous financial year". The indexation factor is for "the financial year". The definition of "indexation factor" is in the Act and is presumably a single number applied annually. Broadcasters must confirm the correct factor each year from the Act.

Seventh, the "remote" classification is residual: any location not falling into high, medium, or low density is remote. This means that some locations that are not particularly remote in a colloquial sense could be classified as remote if they fall outside the defined areas. For example, a location just outside the Perth area but not within the Western Australia low density area (if such area exists) might be remote. The broadcaster must check the boundaries carefully.

Compliance with the determination involves correctly calculating the individual transmitter amount for each transmitter on each licence anniversary. The broadcaster should maintain a record for each transmitter of its authorised location, the band it operates in, its maximum power (as categorised low, medium, or high), and whether it is an alternative transmitter. The population density of the location must be determined by referring to the Radiocommunications (Transmitter Licence Tax) Determination 2015 as at 1 July 2017. That determination contains maps or area descriptions for Sydney, Melbourne, Brisbane, Perth, Adelaide, Newcastle, and the four low density areas. If the location does not fall into any of those, it is remote.

For each transmitter, the broadcaster calculates the uncapped individual transmitter amount as follows. If the transmitter is at a remote location or is an alternative transmitter, the uncapped amount is the minimum uncapped amount for the financial year. That minimum is $39.57 for 2017-18, and for later years is the previous year's minimum multiplied by the indexation factor from the Act. The resulting amount is rounded to the nearest dollar (with 50 cents rounded up) at the final step under subsection 6(2), though the minimum itself is not rounded before use.

If the transmitter is not remote and not an alternative, the broadcaster calculates the formula using dollars per kHz of spectrum bandwidth, spectrum bandwidth, and maximum power factor. The dollars per kHz for 2017-18 is taken from the table in subsection 6(5) using the relevant population density and band. For later years, it is the previous year's dollars per kHz multiplied by the indexation factor, without rounding before multiplication. The spectrum bandwidth is fixed per band as per subsection 6(7). The maximum power factor is 0.1, 1.0, or 10.0 depending on the transmitter's maximum power classification under the licence.

The product of dollars per kHz, spectrum bandwidth in kHz, and maximum power factor gives an amount. If that amount is less than the minimum uncapped amount for the financial year, then the uncapped amount is the minimum; otherwise it is the product. That uncapped amount is then rounded to the nearest dollar.

The individual transmitter amount for the transmitter is the lesser of that uncapped amount and the individual transmitter amount cap for that transmitter for the financial year (which is set by the Act and not by this determination). The broadcaster must know the cap. If the uncapped amount is below the cap, then the individual transmitter amount is the uncapped amount; if it exceeds the cap, the cap applies.

When a licence is varied during the period between anniversaries, the broadcaster must apply section 7 at the next anniversary. The method statement requires the broadcaster to identify the previous tax period (from the last anniversary or from licence commencement or 1 July 2017, whichever is later, to the day before the current anniversary). For each day in that period, the broadcaster calculates the uncapped amount at the start of that day (disregarding section 7 itself). For days before a transmitter was added to the licence, the amount is nil. Then the broadcaster divides that uncapped amount by the number of days in the financial year in which the current anniversary occurs to get a daily amount. The daily amounts are summed over all days in the previous tax period. Separately, the broadcaster gets the uncapped amount at the start of the previous tax period. If the total of daily amounts exceeds that start amount, the uncapped amount on the current anniversary is increased by the difference; otherwise it is decreased by the difference. Importantly, for the daily amount calculation, subsection 7(3) requires treating each day as if it occurred in the financial year when the previous tax period started. So even if indexation would normally update the dollars per kHz or minimum on 1 July, that indexation should not be applied when calculating the daily amount for days after 1 July; the pre indexation figures are used for the entire previous tax period.

Broadcasters should document all variations to licence conditions (power changes, band changes, location changes, addition or removal of transmitters) and the dates they took effect. The uncapped amount at the start of each day must be recalculated whenever a variation occurs, because the uncapped amount depends on the transmitter characteristics at that time. The determination does not require daily granularity for stable periods, but the method statement technically requires a daily amount for each day. In practice, for days before a variation, the daily amount is constant. For the day of the variation itself, the start of that day presumably has the old characteristics; the new characteristics apply from the next day. The determination is not explicit on the time of day a variation takes effect, but the licence conditions usually specify an effective date. Reasonable interpretation would use midnight as the boundary.

Finally, the broadcaster must ensure that the cap from the Act is correctly identified each year. If the cap is indexed, the same indexation factor may apply. The broadcaster should also maintain records of the indexation factor used each year, which can be obtained from the Act or from official publications. The determination does not publish the factor; it must be sourced separately.
