File sales tax on time across every jurisdiction

What you're doing here: Pulling together everything you sold this month so you've got the right numbers for your tax calculations.

Start by exporting sales reports from every channel you use - your POS system, Shopify, WooCommerce, Amazon, and anywhere else transactions happened. You'll need totals broken down by jurisdiction (state, county, city), not just a grand total. Make sure you're separating out exempt transactions and double-checking that all the dates fall within this filing period - a mis-dated transaction in the wrong month can cause headaches later.

Key Actions:
- Export reports from each sales channel
- Categorize by jurisdiction (state, county, city)
- Flag exempt vs taxable transactions
- Verify date range accuracy

Tip: If you're doing this manually, a spreadsheet template by jurisdiction saves a lot of time.

What you're doing here: Catching any gaps between what you actually collected and what you should have collected.

Take the sales data you compiled and calculate the tax that should've been collected per jurisdiction based on the applicable rates. Then compare that against what your system actually collected. You're looking for variances - and when you find them, you need to document why they exist. Common culprits include rate changes mid-month, system configuration errors, or manual overrides that didn't get properly recorded.

Key Actions:
- Calculate expected tax per jurisdiction
- Compare against actual collections
- Document all variances with reasons
- Create reconciliation worksheet

Tip: Don't skip the "why" on variances. You'll thank yourself if you're ever audited.

What you're doing here: Making sure your exemptions will actually hold up if anyone ever takes a close look at them.

Pull up the list of tax-exempt transactions from this month and verify that each one has a valid certificate on file. You're checking three things: the certificate is still current (not expired), it covers the specific type of transaction, and it's stored somewhere you can actually find it. If a customer's certificate is expired or doesn't match the exemption claimed, reach out now - don't wait until a deadline is looming.

Key Actions:
- Pull list of exempt transactions
- Match each to a valid certificate
- Check expiration dates
- Request updates for expired or missing certificates

Audit Risk: Invalid exemptions create direct liability exposure - this step's worth doing carefully.

What you're doing here: Filling out the actual returns for every jurisdiction where you've got a filing obligation.

Work through each state, county, and local jurisdiction one by one. You'll be entering your taxable sales, exempt sales, any deductions you're entitled to, and the tax you collected. Don't forget to calculate use tax if your business made any out-of-state purchases that weren't taxed at the source. Before you move on, confirm that all the amounts match what's in your reconciliation worksheet from Step 2.

Key Actions:
- Complete returns for each jurisdiction
- Enter taxable and exempt sales
- Calculate use tax on out-of-state purchases
- Verify amounts match reconciliation worksheet

Quality Check: Go through your calculations twice before submitting - it's much easier to catch errors now than to file an amendment.

What you're doing here: Getting everything submitted and paid on time - this is the step that actually matters most for avoiding penalties.

Log into each state portal and file the returns you prepared. Schedule your ACH payments or mail checks so they arrive before the due date. Every submission gets a confirmation number - save them all. You'll want them if a state ever claims they didn't receive your filing.

Key Actions:
- File via each state portal
- Schedule or submit payments
- Save all confirmation numbers
- Document payment amounts and dates

Critical: Late filings trigger penalties and interest. If you're running close to a deadline, file even if you need to estimate - you can amend later.

What you're doing here: Putting everything away properly so you're not scrambling if there's ever a question about this month's filings.

Save copies of all submitted returns, payment confirmation pages, and your reconciliation worksheets in your tax records folder. Then open your filing calendar and set the due dates for next month. While you're at it, note any rate changes you ran into this month or any new nexus obligations you discovered - your future self will appreciate having it written down.

Key Actions:
- Archive returns and confirmations
- Store supporting worksheets
- Update next month's deadlines
- Note rate changes for future filings

Record Retention: Keep all of this for at least 4 years - most states can audit that far back.

What you're doing here: Checking whether you've crossed any thresholds that now require you to file in states you haven't filed in before.

Look at your sales by state and compare them against economic nexus thresholds - these vary, but the typical range is $100K in sales or 200 transactions. Also check whether any employees started working remotely from a new state this month, or if you've established any new physical presence anywhere. If you've crossed a threshold, you need to register before you start collecting tax there - not after.

Key Actions:
- Review sales by state for threshold triggers
- Check for new employee locations
- Identify any new physical presence
- Register for permits in new jurisdictions

Compliance Note: Registering late is better than not registering at all, but get it done as soon as you know you've crossed the line.

What you're doing here: Doing a final review to confirm this month is truly wrapped up before you close it out.

Go through each item: did every jurisdiction get filed on time? Are all payments confirmed? Is everything archived? Are next month's deadlines on the calendar? If anything's outstanding, flag it now and assign it to someone before you sign off. This step is your last chance to catch anything that slipped through.

Checklist Items:
- All jurisdictions filed on time
- All payments confirmed
- All records archived
- Next month's deadlines calendared
- Outstanding issues documented

Sign-off: Once you've confirmed everything's complete, mark this month closed. It's a good feeling.
