Frequently Asked
Do you work with clients outside the US?
Yes. We work with individuals and businesses internationally. Please mention your country of residence in your message so we can outline how our services apply to your situation.
How many transactions do I need to have?
Our tax return service is designed for portfolios with more than 50 annual transactions. For smaller volumes, our portfolio reconciliation service may be a better fit.
Do you provide tax advice?
We provide accounting records and schedules to support your tax professional. We do not provide legal or tax advice, but our deliverables are structured to make your tax professional's work more efficient.
