Short-term rental — business vs. other income & how comprehensive income tax reporting differs

You may want extra income from short-term rentals, but tax filing can feel overwhelming.

“Should I report this as business income or as other income?”

“If I report it wrong, will I face penalties later?”

The distinction depends on the rental type and scale.
Below we summarize the criteria and ways to simplify filing.

How do business and other income differ?

What’s the standard for classifying short-term rental income?

Generally, if you register as a business and rent repeatedly or continuously, it’s treated as business income.
If it’s occasional and small-scale—one or two listings—it’s often treated as other income.
These criteria consider frequency, duration, and repetition together, so gray areas are common.
For a definitive classification, check with a tax accountant or the National Tax Service (126).

Why does this change the reporting method?

Business income requires business registration but allows broader deductible expenses; it also clearly triggers annual comprehensive income tax filing.
Other income uses different withholding rules and has a narrower scope for deductible expenses.
So classification affects both the tax amount and the filing steps.

Checklist before you decide

① Are you operating repeatedly/continuously?
② Have you registered as a business?
③ How many listings and how much income?
④ Is this a side income or a main business?

Sorting these four points first speeds up any consultation with a tax professional.

Income calculation also depends on fee structure

If you report as business income, operational costs can be deducted as expenses.
If a platform charges a 3.3% fee like Samsam M2, you’ll have more deductible items but more complex calculations.
plott LIFE charges ₩0 (current), so there’s no commission item to deduct, making income calculation simpler.
However, classification and filing obligations are required regardless of fees.

Remember this before filing

If you operate repeatedly and have business registration, it’s likely business income; if it’s occasional and small-scale, it’s often other income.

If it’s unclear, confirm with a tax accountant or the National Tax Service (126).
