Sri Lanka YouTube & AdSense Tax Calculator
See exactly how much US tax Google withholds from your YouTube and AdSense earnings as a Sri Lankan creator — in dollars and rupees — and how much you lose by not submitting a W-8BEN. No signup, sources cited below.
How it works
When you earn from YouTube's Partner Program or AdSense, Google is a US company paying you from the United States, so it must withhold US tax on the US-sourced part of your income. For a Sri Lankan creator the rule splits into two cases, both published by Google and the IRS.
Case A — your US tax info (Form W-8BEN) is on file. Google withholds only on the earnings tied to your US audience, at the statutory 30% royalty rate. There is no reduced rate for Sri Lanka because it has no US income tax treaty (IRS Publication 901 lists the treaty countries; Sri Lanka is not among them). The formula is:
- usPortion = earnings × US-share
- withheld = usPortion × 0.30
- net = earnings − withheld
Case B — no valid tax info. Google applies undocumented-payee withholding on your total worldwide earnings — 24% for individuals, 30% for businesses — regardless of where your audience is:
- rate = individual ? 0.24 : 0.30
- withheld = earnings × rate
The tool converts every figure to rupees using a CBSL-anchored USD→LKR rate you can edit — there is no live currency feed, so results are deterministic. It also runs both cases side by side to show your annual saving from submitting tax info. Because Sri Lanka has no treaty, submitting does not zero out the tax; it caps it to 30% of your US slice instead of a flat rate on everything. Those two costs are equal at exactly an 80% US-audience share for individuals (30% × 0.80 = 0.24), so below 80% submitting is cheaper — which covers almost every Sri Lankan channel. Each rate in the tool is a named constant with its IRS or Google source cited in the code, last verified on 2026-07-11. The calculator's per-slice breakdown is independently cross-checked by summing each slice, so the headline number and the table always agree.
