Projection events

The most common events that may trigger a large tax bill for american expats included:

Significant increase in wages
Planned excessive stay in the U.S.
Change in one’s filing status (single <-> married)
Commencing withdrawal from pension fund
Starting a business
Sale of property
Disposition of stocks resulting in capital gains
Severance payment from former employer
Moving to another country

Our Tax projection service will help you determine how much money you have to set aside for future tax obligations in order to avoid getting caught off-guard by an unexpectedly high tax bill (and IRS penalties for underpayment of estimated taxes ).

This service requires a retainer, with credit remaining to finalize your return when you obtain the final information.

Tax Projection deliverables include:

Draft of form 1040
Vouchers for the estimated IRS payments.

The goal of this service is to help you get ready for the upcoming tax season and avoid potential tax penalties (that will certainly happen if you are not prepared).

The tax projection is quantitative. If you would like to get advice on the moves you can make now that could minimize your anticipated tax bill we can offer you the Tax Planning Consultation service which is a qualitative discussion on the phone.
