Post-Mortem of Tax Filing Season: Build Better SOPs from What You’ve Learned

As an accountant who’s just come out of another whirlwind tax season, I can tell you one thing: tax filing doesn’t just reveal numbers—it reveals patterns, problems, and opportunities.

Every year, I help clients clean up what’s been missed, misunderstood, or misfiled. And while it's tempting to breathe a sigh of relief and move on, now is the perfect time to look back, assess, and rebuild your business systems.

Because here’s the truth: a smooth tax season starts months before the deadline—and strong SOPs make it possible.

🔍 What Tax Season Reveals (That You Shouldn’t Ignore)

Over the years, I’ve noticed a few red flags that always show up during tax time:

• Sales not matching BIR declarations

• Unfiled or missing Official Receipts and Sales Invoices

• Disorganized expense documentation

• Underreported or overlooked input VAT

• Unreconciled bank and book balances
  
  

These aren’t just “bookkeeping problems”—they're symptoms of broken or missing Standard Operating Procedures (SOPs).

📌 Why SOPs Are Not Just for Big Corporations

Small businesses often skip SOPs, thinking they're too formal or rigid. But that mindset is exactly what leads to ₱20,000–₱50,000 in penalties (or worse, full-blown audits). I’ve seen it too many times.

SOPs don’t need to be fancy. They need to be:

• Clear (step-by-step)

• Consistent (everyone follows the same process)

• Compliant (aligned with BIR requirements)
  
  

✍️ What You Should Document Post-Tax Season

Here’s what I recommend you document now, while your tax season memories are fresh:

1. Sales Documentation Flow

How do you issue sales invoices or receipts?
Where do you file them?
Who logs them into the system?

📝 SOP Tip: “All issued ORs must be scanned and uploaded to the shared drive within 2 days.”

2. Expense & Petty Cash Protocol

Do you collect supporting documents?
Do you categorize expenses properly?
Are you tracking actual cash releases?

📝 SOP Tip: “All expense reimbursements must have an attached scanned official receipt with VAT and BIR-registered details.”

3. Bank Reconciliation Timeline

When and how do you reconcile your books vs. bank statements?
Is there a monthly routine or is it always last minute?

📝 SOP Tip: “Monthly bank reconciliation must be completed by the 10th of the following month.”

4. VAT Filing Review Steps

Is there a review process before submitting your 2550M/2550Q?
Do you compare input VAT vs. encoded expenses?

📝 SOP Tip: “VAT filing must be reviewed by at least one other person before submission.”

5. Document Archiving System

Where do you store hard copies and digital backups?
Can someone else easily find your 2307s or BIR returns?

📝 SOP Tip: “All BIR returns and attachments must be filed by month in both hard copy folders and a labeled Google Drive folder.”

🧩 Final Thoughts: Make the Post-Mortem Count

Tax season is a test. If it stressed you out, exposed gaps, or cost you more than it should have—don’t let that lesson fade.

This is your moment to build something better.
