Received or made gift but forgot return — what now?

Gift tax return due before 1 March of year after gift. Forgot? Plan:

1. File belated return ASAPTax Office has online "belated gift return" form
2. Invoke INKEER scheme (AWR 67n)voluntary disclosure before Tax Office detects, penalty heavily reduced or waived if no intent
3. Return WITHIN 2 YEARS of giftpenalty up to 100% possible on unexplained discovery, but inkeer typically 5-20%
4. 2-12 years post-giftinkeer possible but larger penalty
5. AFTER 12 yearsfor non-NL gifts assessment still possible (foreign-concealed rule). NOTE: BEFORE INSPECTOR CONTACTS YOU — otherwise not voluntary inkeer. Practical: doubt about year or amount: file with "wrongly forgotten / new information discovered" — honest approach rewarded. For child gifts above annual exemption not declared: look-back years count for raised one-off exemption (affects later planning).
