Air Transportation Excise Tax: Regular vs Alternative Method

The Air Transportation Excise Tax is a federal excise tax imposed on amounts paid for the transportation of persons and property by air. These taxes are reported quarterly using IRS Form 720, specifically for the following IRS tax numbers:



These taxes must be deposited on a semi‑monthly basis when the quarterly net tax liability exceeds a certain threshold, and businesses must comply with Form 720 filing schedules.


Air Transportation Excise Tax - Key Points

Under the Air Transportation Excise Tax, the taxes cover transportation services like ticket sales, transportation of cargo, and utilization of international air transport facilities. The taxes are remitted to the IRS by air carriers. The tax rate varies according to the kind of service offered, as per IRC Section 4261 and IRC Section 4262.



IRC § 4261 imposes a 7.5% tax on the amount paid for air transportation of passengers. IRC § 4262 imposes an excise tax on the transportation of property by air, calculated at a flat rate per 100 pounds of property transported in domestic commerce. Form 720 is used to report these liabilities on a quarterly basis, but the semi‑monthly deposits and quarterly filing are separate requirements under IRS rules.


Form 720 requires excise taxpayers to report these liabilities in Part I and to use Schedule A to capture deposits based on semi‑monthly periods. Schedule A distinguishes between two classes of deposit reporting:


Regular method – entered in Line 1

Alternative method – entered in Line 2 (for select IRS numbers)


These payments are made based on the semi‑monthly deposit requirement, which is due if the liability exceeds the IRS threshold.


What Is a Regular vs Alternative Method in Air Excise Tax?

The Regular vs Alternative Method in air transportation excise tax pertains to how deposits are reported and when those deposits are due. These methods do not change the calculation of the tax, but they determine the timing of the deposits.


Semi‑Monthly Deposits

The IRS requires excise tax deposits for Part I excise tax categories to be made semi‑monthly. This means businesses must submit their excise tax deposits twice a month based on amounts collected. The deposits are due on the following schedule:


Period 

Deposit Due By 

1st to 15th of the month 

15th of the following month 

16th to end of the month 

Last day of the following month 


The threshold of $2,500 applies to taxpayers who are required to deposit excise taxes semi‑monthly. If a taxpayer’s quarterly net tax liability exceeds $2,500, they must adhere to this deposit schedule. This threshold amount is confirmed by the IRS Form 720 Instructions.


Regular Method

The Regular Method is the most common method for depositing excise taxes. Under this method:

  • A taxpayer reports taxes actually collected during each semi‑monthly period.

  • Deposits are made twice per month as per the schedule outlined above.


Example – Regular Method Deposit


1)Suppose an airline collects $10,000 in air transportation excise tax from ticket sales between January 1st to January 15th. The deposit for this collection will be due on February 15th.

2)If the airline collects $15,000 between January 16th and January 31st, the deposit for this second period will be due on February 28th.


Thus, the deposits are based on actual collections, and the timing is governed by the IRS semi‑monthly deposit schedule.



Alternative Method


The Alternative Method is a special reporting method available for certain IRS tax numbers, specifically for IRS No. 22 (communications excise taxes) and IRS Nos. 26, 27, and 28 (air transportation excise taxes). This method allows taxpayers to deposit taxes based on amounts billed or tickets sold rather than actual receipts collected.


Criteria for Alternative Method


When using the Alternative Method, the tax is treated as deemed collected at the time that the bill is sent or at the time that the ticket is sold. This type of treatment is usually applied in cases where there is an inconsistency between the dates of the bill or ticket being issued and payment actually being received.


Deposits under the Alternative Method are reported on Line 2 of Schedule A in Form 720. The due dates for deposits are also tied to the timing of billing or ticket sales.

Regular Method and Alternative Method - Which is better?

Criteria 

Regular Deposit Method 

Alternative Deposit Method 

Deposit Frequency 

Semi‑monthly deposits (twice per month) for the first 15 days and the last days of the month. 

Flexible deposit timing based on when amounts are billed or tickets are sold. 

Calculation Basis 

Based on actual tax collected during the semi‑monthly periods. 

Based on amounts billed or tickets sold, not actual cash received. 

Flexibility 

Less flexible. Requires two fixed deposit periods each month. 

More flexible. Based on billing cycles, useful when cash flow doesn’t align with actual collections. 

Best Suited For 

Businesses with predictable cash flow and regular collections

Businesses that bill or sell tickets in bulk, and need flexibility in deposit timing. 

Complexity 

Straightforward but requires strict adherence to IRS deposit dates. 

More complex due to the flexibility in deposit timing and tracking of billed amounts. 

Compliance Risk 

Lower risk of late deposits if following the semi‑monthly schedule. 

Higher compliance risk due to reliance on proper tracking of billed amounts and their deposit timing. 


Which Method is Best?

  • Regular Deposit Method: Best for businesses with regular, predictable cash flow and tax collections.

  • Alternative Deposit Method: Ideal for businesses with variable billing cycles or those who need flexibility in their deposit schedules, allowing them to report based on when amounts are billed or tickets are sold.
