The Scenario
You're a tax consultant and you're onboarding a new client — a multi-state e-commerce brand that's been operating for four years but has never had a proper nexus overview. Before you can build a compliance calendar or advise on filing frequency, you need a single reference workbook showing the minimum and average sales tax rates for every state where they have nexus.
TaxJar has that data. It's just not in an Excel workbook.
The bad version:
- Navigate to TaxJar's rate summary section, click each state, copy the minimum and average figures into a worksheet row, switch tabs, repeat for the next state. The client has nexus in 22 states.
- Look for a TaxJar export of rate summaries, find it doesn't exist as a UI feature, start reading API documentation, realize you need to write a script to loop through the states endpoint.
- Spend an hour on a script that could have been spent on the actual compliance analysis — the thing the client is paying you for.
You're onboarding three clients this quarter. You can't spend an hour per client on rate table setup. The value you deliver is the analysis, not the data retrieval.
The Easy Way: One Prompt in SheetXAI
SheetXAI is an AI agent that lives inside your Excel workbook. It reads the open workbook and through its built-in TaxJar integration it fetches the summarized rate data for every region and writes it into the workbook — one row per state, ready to reference.
Open the SheetXAI sidebar and type:
Fetch TaxJar's summarized tax rates for all regions into this Excel sheet with state, minimum rate, average state rate, and average combined rate in separate columns
What You Get
- One row per state with state name, minimum combined rate, average state rate, and average combined rate.
- Rates sourced from TaxJar's current summary data — not a static table you'd have to update quarterly.
- The workbook is ready to filter, sort, or reference from your compliance calendar without any reformatting.
What If the Data Is Not Quite Ready
You only want the states where your client has nexus
The client has nexus in 22 specific states. Pulling all 50 and then deleting rows is an extra step.
Pull TaxJar regional tax rate summaries only for these states: CA, TX, NY, FL, IL, PA, OH, GA, NC, VA, WA, NJ, AZ, MA, TN, IN, MO, MD, WI, MN, CO, SC — write state, minimum rate, and average combined rate to this workbook
You want the data sorted by rate for a presentation
The deliverable is a slide with the client's nexus states sorted from highest to lowest average rate.
Pull TaxJar regional rate summaries for all nexus states (CA, TX, NY, FL, IL, PA, OH, GA, NC, VA, WA, NJ, AZ, MA, TN, IN, MO, MD, WI, MN, CO, SC), write state and average combined rate to columns A and B, then sort the rows from highest to lowest combined rate
You want the breakdown columns separated for the model
Your compliance model has dedicated cells for state base rate and average combined rate — they can't be in the same column.
Pull TaxJar's summarized tax rates for all regions — write state name to column A, minimum rate to column B, average state rate to column C, and average combined rate to column D
The kill chain: pull, cross-reference nexus list, flag high-rate states, and summarize
Pull TaxJar regional rate summaries for all states and write to this workbook with state in column A, minimum rate in column B, average combined rate in column C — cross-reference against the nexus state list in column E and write "nexus" in column D for matching states, then flag any row where average combined rate exceeds 9% with "HIGH RATE" in column F
One prompt pulls the TaxJar data, applies the nexus filter, and adds the analysis flags in a single pass.
