Small companies file profit and loss accounts Companies House 2028. Starting April 2028, small UK limited companies and micro-entities must deliver a full profit and loss (P&L) account alongside their balance sheet. They can opt out of public publication though. This shift scraps abridged accounts and boosts transparency while easing some privacy worries.
- What it means: More detailed filings for Companies House, but smaller firms avoid full public exposure of sensitive margins and costs.
- Why now: Part of broader reforms under the Economic Crime and Corporate Transparency Act to fight fraud and improve data quality.
- Deadlines matter: Accounts are due nine months after your year-end. Miss them and face automatic penalties starting at £150.
- Software shift: Everything goes through commercial software—no more simple web or paper filings.
- Bottom line: Get your bookkeeping tight today to avoid scrambling later.
Here’s the thing. Many US founders running UK subsidiaries or considering incorporation there get caught off guard by these rules. Even if you’re stateside, a UK entity demands compliance with Companies House. Nail this or risk director headaches and public scrutiny.
Why Small Companies File Profit and Loss Accounts Companies House 2028 Matters
For years, small companies could “fillet” their filings—sending just a balance sheet and skipping the P&L. That privacy blanket disappears in 2028. Competitors, suppliers, and lenders will see more, unless you opt out of publication.
The kicker? This isn’t just red tape. Better filings build credibility with banks and investors. But sloppy ones expose weaknesses. In my experience, businesses that treat accounts as a strategic tool rather than a chore stay ahead.
Qualifying as small or micro (updated thresholds post-2025):
| Category | Turnover | Balance Sheet Total | Avg Employees |
|---|---|---|---|
| Micro-entity | ≤ £1m | ≤ £500k | ≤ 10 |
| Small company | ≤ £15m | ≤ £7.5m | ≤ 50 |
Meet two out of three for two consecutive years (or your first year). These numbers let you use simplified regimes, but the 2028 rules still require filing that P&L.
Before vs After: The 2028 Shift for Small Companies File Profit and Loss Accounts Companies House 2028
Expect real operational impact.
Old way: File abridged or filleted accounts. Hide gross margins and operating costs from the public register.
New reality from April 2028:
- Mandatory P&L filing for small companies and micro-entities.
- No more abridged accounts.
- Opt-out available for public publication of the P&L (details coming soon).
- Full software-only submission in iXBRL format.
- Directors’ report and (if applicable) auditor’s report for small companies.
This change levels the playing field somewhat. Larger firms always disclosed more. Now smaller ones contribute richer data to the public record—while gaining opt-out protection against commercial snooping.
Step-by-Step Action Plan for Beginners
Don’t panic. Break it down.
- Confirm your status. Pull last year’s numbers. Turnover, assets, headcount. Use Companies House guidance or your accountant.
- Upgrade your bookkeeping. Switch to software that handles FRS 102 (small) or FRS 105 (micro) and exports iXBRL. Test filings early.
- Prepare full statutory accounts. For members (shareholders), you’ll need the complete set anyway. P&L becomes non-negotiable for Companies House too.
- Choose filing method. Pick approved commercial software. Many offer bundles with HMRC CT600 filings.
- File on time. Nine months after year-end. Set calendar reminders. Appoint an accountant if numbers overwhelm you.
- Opt out if eligible. When the process rolls out, flag your desire to keep P&L private on the register.
What I’d do if I were you: Run a mock filing six months before your deadline. Spot gaps in tagging or disclosures early. Saves fees and stress.

Common Mistakes & How to Fix Them
- Ignoring the software mandate. WebFiling dies for accounts. Fix: Research providers now. Many have free trials.
- Mixing up member accounts vs filed accounts. Prepare full ones for owners; file the required package for Companies House.
- Late filing. Penalties escalate fast and hit credit scores. Fix: Automate reminders and outsource if needed.
- Wrong size classification. Leads to rejected filings. Fix: Document qualifying criteria clearly each year.
- Forgetting audit exemption statements. New rules demand specific director wording. Fix: Use templates from trusted sources.
The real trap? Treating this as “just paperwork.” It reveals business health. Get it right and it becomes a strength.

Practical Tips from the Trenches
Track expenses religiously. Clean categorizations make P&L prep painless. Review quarterly—don’t wait until filing season. Consider how public data might affect negotiations with suppliers or talent.
US readers: If your UK company is a subsidiary, align with group reporting. Differences in GAAP vs. FRS can bite during consolidation.
One analogy that sticks: Filing accounts is like getting a yearly physical. Skip the full exam and you might miss something serious. The 2028 rules just require the complete bloodwork.
