Tania Sebastian’s practice focuses on domestic and international estate planning, including general estate planning, complex tax planning, charitable planning, pre-immigration planning, pre-expatriation planning, business succession and offshore voluntary disclosure reporting.

Tania helps her clients with estate planning that fits their specific circumstances, family dynamics, tax objective, and charitable wishes, often implementing sophisticated trust planning, including insurance trusts, dynasty trusts, GRATs, and charitable trusts.

Tania also works with foreign individuals who are considering residing in the US, temporarily or permanently, and who want to benefit from pre-immigration tax planning, with respect to their foreign and US assets. Tania assists foreign based individuals who want to develop an estate plan for their US property interests and/or make gifts to US individuals, in the most tax efficient way and in furtherance of personal objectives.

Tania works with clients who want to become US tax compliant with respect to their foreign asset and/or foreign income reporting, often through the IRS’ offshore voluntary disclosure program or streamlined procedures.

For those individuals who are considering expatriating from the US, Tania provides pre-expatriation tax planning, including a review and application of the US exit tax if the individual is a “covered expatriate”. The exit tax includes a “mark to market” tax on a covered expatriate’s worldwide assets that may be minimized with pre-expatriation planning.

Tania advises clients on their charitable giving, including creating and operating private foundations, by filing for tax exemption with the IRS, advising private foundations regarding their responsibility and expenditure requirements for grants to domestic and overseas charitable organizations, advanced rulings for scholarship grant programs, and working with local counsel in multiple overseas jurisdictions to attain local NGO status. Tania also advises other “501(c)” organizations on formation and compliance issues.

Tania is committed to the firm's pro bono initiative and regularly assists new non-profits on a pro bono basis to help them with their state and IRS filings.
