What This Means for You, Business Owner: Your accounting method affects when income and expenses show up — and December decisions can change the picture.
One of the most important — and misunderstood — questions at year‑end is:
“Am I cash or accrual?”
Most business owners think they know the answer. Many have never actually confirmed it.
This post is part of our 3‑month series (December–February) on how to work effectively with your bookkeeper and tax preparer so year‑end decisions actually hold up.
Here’s why this matters in December specifically:
Your accounting method determines when you recognize income and expenses. It impacts both the appearance of your books and the preparation of your tax return.
• Cash basis generally follows money in and money out
• Accrual basis follows when income is earned and expenses are incurred
Those differences directly affect:
- Which December payments matter
- How invoices, retainers, and bills are treated
- What decisions still impact the current tax year
You don’t have to guess.
Your accounting method is listed on your most recent business tax return (Forms 1120 or 1120‑S).
Here’s the critical part many owners miss:
If you are an accrual‑basis taxpayer, this isn’t just a December issue. It affects how your books should be maintained all year long.
When books are kept like cash but taxes are filed on accrual:
- CPAs have to rework the books
- Tax prep takes longer
- Fees are often higher
- Extensions become more likely
And it’s also important to set expectations:
If you are an accrual filer, it’s normal — and appropriate — for your bookkeeping fees to be higher.
Accrual accounting requires:
- More detailed tracking
- Ongoing adjustments
- Stronger coordination between bookkeeping and tax prep
That added complexity takes more time and expertise. Once you truly understand what accrual means, the pricing usually makes sense — and it supports cleaner books, smoother tax prep, and fewer surprises.
Your bookkeeper can apply the method — but your tax preparer determines what’s appropriate based on your full tax picture and current tax law.
Key takeaway:
December decisions only help if they align with the accounting method you are actually using.
Your action item:
Check your most recent tax return to confirm whether you are cash or accrual. If you use the accrual method, meet with both your bookkeeper and tax preparer to confirm your books are accurate before year-end.
If you haven’t already, the Year‑End Financial Checklist can help surface timing questions that are tied to your accounting method.
No bookkeeper yet? Cash vs accrual confusion is one of the most common reasons year‑end turns stressful. This series will help you understand what kind of support you actually need before tax time.
