Directors can claim expenses that are incurred wholly, exclusively, and necessarily for business purposes, reducing the company’s taxable profit. Key allowable expenses include travel and subsistence (excluding daily commuting), office supplies, equipment (e.g., laptops), telephone/internet bills, professional subscriptions, insurance, and training.

In most cases you would keep your salary lower and pay yourself dividends as it is more tax efficient. It is important to note that dividends can only be paid if a company has made a profit, so past losses could mean the only way to take more money out of the business is via salary not dividends.
The most tax-efficient director's salary in 2025-26 is either £5,000, £6,500, or £12,570. These are based on the following thresholds for Class 1 National Insurance contributions (NICs) and the Personal Allowance: The NIC Secondary Threshold of £5,000 per year.

100% write-offs, primarily through bonus depreciation, allow businesses to immediately deduct the full cost of qualifying new and used assets (like equipment, machinery, vehicles, and certain improvements) in the year they're placed in service, rather than depreciating them over years, significantly boosting cash flow and lowering taxes, with recent laws making this 100% deduction permanent for assets acquired after January 19, 2025. This is a major tax incentive under recent legislation, often used alongside Section 179 expensing, which offers its own high deduction limits, notes Forbes.
List all your expenses. Then, list all your monthly expenses. This includes needs, like your electricity bill and groceries; wants, like streaming TV subscriptions and take-out; and even planned savings, like monthly contributions to your 401(k) or emergency fund.
