The 10 Costliest Maritime Tax Mistakes

# Mistake Description Severe Consequence Correct Legal Action
1 Filing ITR-1 Sahaj Deemed resident; foreign salary taxed up to 30% Always file ITR-2 with Schedule EI
2 Skipping ITR Filing Altogether Section 148A reassessment notice for AIS credits File ITR-2 annually to disclose exempt foreign wages
3 Counting Airport Passport Stamps Miscounts Rule 126 sign-on/sign-off inclusion Count days strictly from CDC sign-on to sign-off
4 Retaining Resident Savings Accounts FEMA Section 13 penalty (up to 3x sum) Convert to NRE & NRO accounts promptly
5 Ignoring AIS Code S0014 Remittances Computerized CPC scrutiny notice Submit proactive online feedback on AIS portal
6 Counting Coastal Days as Foreign Days Disallowance of NRI status during audit Segregate coastal domestic runs from FG voyages
7 Trading Derivatives (F&O) on Resident Demat FEMA violation & mandatory business audit (44AB) Use authorized NRO trading or avoid derivatives
8 Transferring Foreign Salary to HUF Directly Section 64(2) clubbing of income in personal hands Capitalize HUF via gifts from relatives or inheritance
9 Selling Property Without Form 13 23.92% TDS withheld on gross sale value for 18 months Apply for Form 13 Lower TDS Certificate upfront
