Key takeaways
- Plan content around the UK tax calendar: Self Assessment, year end, payments on account, VAT quarters and Budgets.
- Use a weekly content mix: tips, deadlines, stories, behind the scenes and engagement.
- Batch-create and schedule posts monthly, leaving room for news and reactive posts.
- Check every date and figure against the current tax year before publishing.
- Review what led to enquiries each month and adjust.
A content calendar turns social media from a last-minute chore into a planned activity. For accountants, the tax year provides a ready-made structure: there is always a deadline, change or seasonal topic your clients need to hear about.
A month-by-month calendar
| Month | Key dates and themes | Content ideas |
|---|---|---|
| January | Self Assessment deadline (31 January), first payment on account | Countdown posts, “what you need for your return”, late filing penalties |
| February | After the deadline, quarterly VAT | Penalties explained, planning for the year ahead, MTD quarterly update deadline (7 February) |
| March | Tax year end approaching (5 April) | Year-end checklists: pensions, ISAs, dividends, allowances |
| April | New tax year (6 April), new rates | What has changed, new rates and thresholds, minimum wage rises (1 April) |
| May | P60s by 31 May, MTD update (7 May) | Employer reminders, understanding your P60 |
| June | Planning season | Mid-year reviews, cash flow tips |
| July | P11D (6 July), second payment on account (31 July), MTD update (7 August next) | Benefits in kind, payments on account explained |
| August | Quieter period | Behind the scenes, team stories, planning for autumn |
| September | Back to business | Growth tips, company year-end planning |
| October | Register for Self Assessment by 5 October; paper returns by 31 October | Who needs to file, getting organised early |
| November | Autumn Budget (usually), MTD update (7 November) | Budget reactions and what it means for clients |
| December | Year-end for many companies, festive | Staff party tax rules, trivial benefits, a seasonal message |
VAT, Corporation Tax and company year-end dates vary by client, so add the dates that matter to your client base.
A weekly content mix
A sustainable rhythm for most firms is three posts a week:
| Day | Content type | Example |
|---|---|---|
| Monday | Practical tip | ”One expense landlords often miss” |
| Wednesday | Deadline, news or explainer | ”Payments on account in 60 seconds” |
| Friday | Story or behind the scenes | ”Meet our new payroll specialist” |
Add one engagement post, such as a poll or question, every couple of weeks. See 50 LinkedIn content ideas.
A simple planning template
Use a spreadsheet or a planning tool with these columns:
| Date | Platform | Topic | Format | Copy | Link | Image or video | Owner | Status |
|---|
- Topic: linked to the calendar theme or a client question
- Format: text, image, video, document carousel, poll
- Link: a relevant guide on your website, if any
- Owner: who writes or approves it
- Status: idea, drafted, approved, scheduled, published
Planning and batching
- Monthly planning session: an hour to choose topics for the coming month.
- Batch writing: draft all posts in one or two sessions.
- Review: check dates, rates and compliance.
- Schedule: use a scheduling tool or native scheduling; see scheduling tools.
- Leave space for reactive posts about news, Budgets and HMRC announcements.
- Monthly review: which posts led to comments, messages or enquiries?
Repurposing content
One piece of work can feed several channels:
- a blog guide becomes three LinkedIn posts, a short video and a newsletter item
- a webinar becomes clips, a summary post and a downloadable checklist
- client FAQs become a series of short tips
