Depreciation can help a business realize tax benefits, maintain compliance with financial reporting requirements, and project asset replacement. The half-year convention for depreciation is an important practice to understand.

For fixed assets, depreciation is recognized and recorded on a 50 percent basis for the initial and concluding years over its schedule. This supposes that fixed assets have been in service for 50 percent of their initial calendar service year upon acquisition. It’s normally implemented by taxation agencies to limit the upper limits for depreciation attestations to 50 percent of the yearly figures.

The balance of the annual 50 percent depreciation amount is recognized/recorded during the depreciation schedule’s last year, as the fixed asset will be removed from service mid-year. Regardless of the type of depreciation – straight-line, double-declining, etc. – the half-year convention applies equally.

This has been instituted because businesses were tempted to buy fixed assets in the third or fourth quarter of a fiscal year and try to deduct it fully via complete depreciation deduction. However, this convention is explicit in that fixed assets in service on or after July 1 may only deduct half of otherwise normal depreciation schedules.

How It Works

In this example, Production Equipment is purchased for $50,000 on April 1, 2022, with a useful life of 7 years. Using the half-year convention, depreciation is as follows:

Straight-line Depreciations = Cost of Asset / Useful Life = $50,000 / 7 = $7,142.86

Half-Year Convention: $7,142.86 / 2 = $3,571.43

This also assumes that there’s no scrap of salvage value. Although there are 7 years for the item’s useful life, with the half-year convention, it’s treated as 8 years for the depreciation schedule:

Year 1: $3,571.43

Year 2: $7,142.86

Year 3: $7,142.86

Year 4: $7,142.86

Year 5: $7,142.86

Year 6: $7,142.86

Year 7: $7,142.86

Year 8: $3,571.43

Context for Depreciation Convention

A depreciation convention gives context on how depreciation is performed by the company. It guides the company on available depreciation methods based on the asset’s useful life, how much the asset can be depreciated once it’s removed from service, and how depreciation is accounted/claimed in the initial and final year during the asset’s recovery period.

Depending on the situation and the type of depreciation convention involved, the following are some different conventions and how they vary:

• Full Month permits a business to get a complete month of depreciation for the month when the asset has been put in service. There’s no depreciation taken for the month of disposal.
• Next Month permits a business to start recording depreciation for the fixed assets the following month and being able to record one month of depreciation “when disposed of.”
• Actual Days permits depreciation to be recorded for every single day an asset is in service during its fiscal year.
• Mid-Quarter permits depreciation for half of the 3-month business period whenever the asset’s been put in place and disposed of (for both quarters).

Conclusion

While this is illustrative of financial reporting requirements, it’s an important consideration for business owners and their accounting professionals. Optimizing fixed asset depreciation leads to more accurate books, which will help in tax planning.
