Navigate to Dashboard Finances & Payout Settings
Log into Polar.sh, navigate to Organization Settings -> Finances -> Payout Methods. Polar integrates with Stripe Connect Express and specialized crypto distribution rails for international software developers.
Submit Digital W-8BEN Tax Form for 0% US Withholding
Non-US developers must complete the online W-8BEN certification within Polar. Because digital software licenses export qualifies under bilateral tax treaties, properly certified accounts enjoy 0% US withholding tax.
Configure Primary Payout Rail (Crypto Wallet or Wise ACH)
For crypto, input your self-custody EVM wallet address on Polygon or Base. For fiat, input your Wise US checking account ABA routing code (026...) and 10-digit account number.
Configure Payout Threshold & Automated Settlement Frequency
Select between on-demand manual payouts or automatic weekly/monthly sweeps. We recommend setting a threshold of $100 to consolidate transaction reporting and reduce micro-accounting friction.
Execute Compliant Off-Ramping to Local Fiat Account
If using USDC, transfer through regulated regional crypto exchanges or OTC brokers. If using Wise, execute direct CNY/local currency remittance to UnionPay or Alipay with electronic software export invoice proof.

税務コンプライアンス・AML・口座凍結防止策
アカウント停止や税務トラブルを防ぐための必須ガイドライン。
Non-Custodial Wallet Security
Never withdraw commercial revenue directly to exchange deposit addresses that change dynamically. Always withdraw to a hardware or secure multi-sig wallet first.
W-8BEN Exemption Maintenance
IRS W-8BEN tax certifications expire after 3 full calendar years. Polar will alert you before expiration to refresh your certification and maintain 0% withholding.
Rolling Dispute Reserve Management
Polar monitors merchant chargeback ratios. Maintaining a rolling dispute rate below 0.5% guarantees zero delays in your automatic weekly payout schedule.
よくある質問・トラブルシューティング
開発者から寄せられる送金・出金に関する疑問と回答。
Q1:Do I need an overseas entity (US LLC / UK Ltd) to withdraw from Polar.sh?
No. Polar acts as your legal Merchant of Record. You can register and withdraw globally as an individual indie developer using your personal passport without incorporating abroad.
Q2:Which payout rail offers the lowest total fee on Polar.sh?
USDC on Polygon or Base offers the lowest friction. Network gas fees are sub-cent, with zero banking wire deductions, allowing you to retain 95.5%+ of gross revenue.
Q3:How does Polar.sh handle European VAT and US Sales Tax?
Polar calculates, collects, and files all global sales taxes and VAT automatically. You do not need VAT numbers in Europe or individual US state tax registrations.
Q4:How can Chinese or Asian developers safely convert Polar earnings to domestic currency?
Route funds via Wise USD ACH to domestic UnionPay/Alipay (0.6% transparent fee), or off-ramp USDC via regulated regional brokers backed by Polar's official software export invoices.
Q5:When do funds become available for withdrawal after a customer purchase?
Customer credit card payments clear through standard anti-fraud hold periods (typically 3 to 7 business days) before being credited to your withdrawable balance.
