I occasionally take arrangement jobs - do I need to file this as business income?
Continuous, repeated arrangement work is classified as business income (3.3% withholding), while one or two occasional jobs may be classified as other income (8.8% withholding) - frequency of activity is the deciding factor. Since your income structure can also change based on the copyright split with the original songwriter, it is important to first confirm whether your copyright and neighboring-rights share is specified in the contract, and DAW software subscriptions and virtual instrument licenses can be expensed if their business relevance is recognized.

Confirm Copyright Splits Through Contracts
Clearly specifying the copyright and neighboring-rights split with the original songwriter in a contract makes the income classification and tax treatment at settlement much smoother.
Consolidate Income From Session Work and Producing
If you have income from session performance or producing alongside arrangement work, managing it as a single business income stream lets you apply expense ratios and tax-saving strategies like the Nolan Umbrella Fund.
Spread Tax Burden Through Equipment Depreciation
MIDI equipment and audio interfaces over 1 million KRW should be depreciated over time so you can claim stable expenses every year.
The Most Common Mistake in the Field
The most common mistake is agreeing on a copyright split with the original songwriter only verbally without a contract, which often leads to both income classification issues and disputes over shares at settlement time. Without a contract, income classification becomes difficult to determine for tax purposes as well.
