Wadiz & Tumblbug Crowdfunding Tax Guide

From when funding contributions are recognized as revenue to reward production-cost and platform-fee expense treatment — everything covered here.

A funding round ends when the goal is met, but revenue filing ends only after shipping

My Wadiz/Tumblbug campaign overshot its goal — when should I recognize the revenue?

Funding contributions are essentially a pre-order/advance-payment in substance, so the principle is to recognize revenue when the reward is actually shipped or delivered — not when the campaign succeeds. Even if extra production and shipping is delayed because you overshot the goal, recording the entire amount as revenue all at once per the original plan can tangle the timing; we recommend deducting the platform fee separately from the total contribution amount and tracking revenue precisely based on the actual shipping-completion date.

Characteristics of Crowdfunding Income Structure

Contributions received via Wadiz, Tumblbug, and similar platforms are essentially pre-orders/advance payments
A time gap exists between when the campaign succeeds and when the reward actually ships
Extended production and shipping timelines are common when the goal is overshot
Often leads into regular sales through your own store or Smart Store after the campaign
Ongoing reward sales are subject to mail-order sales registration; converts to general taxpayer once annual revenue exceeds ₩104 million

Key Deductible Expense Items

Reward (product) material costs and outsourced production costs
Platform fee (deducted from Wadiz/Tumblbug contributions)
Shipping costs, packaging materials
Funding-page production costs, video/photography fees
Funding-promotion marketing costs

Tax Advantages for Crowdfunding Makers

Manage your tax burden by recognizing revenue at shipping time

Rather than recording the entire funded amount as revenue all at once, recognizing revenue as rewards are actually delivered lets you manage your tax burden more precisely when the timeline spans fiscal years.

Treat the platform fee as a separate expense

You must keep to the structure of recording the total contribution amount — not the settled amount — as revenue, and treating the platform fee as a separate necessary expense.

Consolidate channels if you move into regular sales

If you continue into regular sales on your own store or Smart Store after the campaign, you must manage funding revenue and regular sales revenue together to avoid missed filings.

The Most Common Mistake We See

It's common to record the entire amount raised as revenue all at once when the campaign ends, or to keep recognizing revenue on the original schedule even when extra production and shipping is delayed after overshooting the goal. It's safest to manage revenue based on the actual reward-delivery (shipping) date.
