Tax season does not run on tax knowledge. It runs on paperwork arriving. Every firm knows the pattern: a client sends most of what is needed, one item is missing, the preparer emails, two weeks pass, the deadline gets closer and the same conversation happens across dozens of clients at once.
Here is the checklist that prevents most of it, and why each item matters.
1. Last year's return
If the client is new, last year's return tells the preparer what to expect and what carried forward. Asking for it upfront avoids discovering a missing detail late.
2. Income records
Employment income, self-employment income, pensions and any other income. The point is completeness, not format. Clients often forget small sources entirely, so asking specifically about second jobs, freelance work and casual income prompts better recall.
3. Interest, dividends and investments
Bank interest, dividend statements and investment account summaries. These are the items clients most often assume are already known to the tax authority and therefore not needed.
4. Property
Rental income, allowable costs, mortgage interest statements and any sale or purchase during the year. A property transaction changes a return substantially, so it needs flagging early.
5. Expenses and deductions
Whatever the client is entitled to claim, with records. Explaining what kinds of expenses are commonly claimable in their situation prompts them to look rather than guess.
6. Pension and charitable contributions
Both are regularly forgotten, and both affect the outcome. A specific prompt gets a better answer than a general request for documents.
7. Personal changes
Marriage, separation, a new child, a move, a change of employment status. Clients rarely think to mention these, and each can change the return.
Publishing the checklist
The checklist belongs on the website, not only in an email, so clients can find it at any hour and so an assistant can answer from it. Chasing is covered in onboarding checklists that stop endless document chasing.
Answering the questions the checklist creates
SpideyChat for accountants answers document questions from your published checklist at any hour, so the team is not explaining the same item all January.
Client: Do I need to send my bank statements? Assistant: The checklist explains that full bank statements are not usually needed, but interest certificates and any business account records are. If you are self-employed, the page lists exactly which records to include.
8. Overseas income and accounts
Income, property or accounts held abroad are among the most commonly overlooked items, and among the most consequential to miss. A specific prompt about anything held or earned outside the country gets a far better answer than a general question about income.
9. Anything unusual that happened
A redundancy payment, an inheritance, a share sale, cryptocurrency activity or income from a hobby that grew. Clients rarely volunteer these, because they do not think of them as taxable. Listing examples prompts recall, and catching one early saves an amended return later.
The deadline crush
Everything arrives at once near the deadline, the pattern described in tax deadline rushes that bury accountancy inboxes. Other sectors handle the same seasonal load, as covered in admissions team workload in peak season.
Never advise on the return
The checklist explains what to send. What is claimable, how something is treated and what a client should do are advice questions for a qualified preparer. More on the season is in AI receptionist for accountants in tax season.
