Your flexible answer for sales and use tax outsourcing
We can manage your entire sales and use tax function or just a part of it. All in, we are able to operate as an organizations sales and use tax department.
When fully outsourced to us, you can rest assured that the process will operate smoothly, we’ll keep you informed of necessary information, and everything will be handled with the care it requires. This means we handle everything for you:
- Preparation and filing of returns
- Processing payments
- Booking journal entries
- Implementation and maintenance of technology
- Reviewing and analyzing accruals
- Exemption certificate management (sales & procurement)
- GL account reconciliations
- Issue / notice remediation
- Internal tax technical advisory

Often, even if you are not outsourcing the entire function, compliance is an area to still consider.
The process should be technology enabled and executed by tenured tax practitioners. Our experienced team and automated process provide outsourced compliance at an unprecedented value to the marketplace, so you get the best of both worlds.
Through GTM’s “closed loop process,” you can adjust what you pay before returns are filed. We reconcile your GL as part of the compliance process instead of only considering it after returns are filed.
