Twelve deductions small businesses forget

From home-office costs to software subscriptions, the write-offs owners often miss. Here is the short version we give clients, with the details that matter most.

1. Know your numbers

Before any decision, gather the last twelve months of income and spending. Most people underestimate their monthly outgoings by 15–20%, and that gap changes every answer that follows.

2. Put dates in your calendar now

Missed deadlines are the most expensive mistake we see. Penalties and interest add up quickly, and almost all of them are avoidable with a reminder and an hour of preparation.

The cheapest tax advice is the advice you get before the end of the year, not after it.

3. Keep records as you go

Photograph receipts and save statements monthly. It turns a stressful weekend in April into a twenty-minute job.

4. Ask for help early

If something changes – a new job, a business, a house, a baby – talk to your adviser that month. Small adjustments made early are worth far more than big fixes made late.
