Tax season lives or dies on paperwork. If your clients drip-feed W-2s, forget their 1098s and email you a photo of last year’s return the night before the deadline, you’re stuck doing intake work instead of tax work. A clear tax preparer document checklist, sent to every client at the start of the engagement, is the single easiest fix.<\/p>\n
This checklist covers what to request from individual and small-business clients, how to organise the request so people actually respond, and where things usually go wrong. Copy it, adapt it, and hand it to your team.<\/p>\n
Two things drive whether a client sends everything the first time.<\/p>\n
The first is grouping. A flat list of thirty items reads as homework and gets ignored. Split the request by situation (“employment income”, “investments”, “self-employment”, “kids and dependents”) so clients only see what applies to them.<\/p>\n
The second is a deadline. A checklist with no due date sits in an inbox. A checklist with “please upload by February 20” gets action. Give yourself buffer time \u2014 set the internal deadline at least three weeks before you actually need the file complete.<\/p>\n
If you handle a lot of new clients each year, a written intake process saves hours. Our accounting client onboarding checklist<\/a> covers the full workflow from engagement letter to first document request.<\/p>\n Ask for these on every return, no exceptions.<\/p>\n Verifying names and Social Security numbers against ID at intake catches the mismatches that cause e-file rejections weeks later.<\/p>\n Ask for the prior-year return even if you filed it. It’s the fastest way to spot the recurring items you’d otherwise have to chase down: rental depreciation schedules, K-1 sources, credit carryforwards.<\/p>\n Request whichever apply. Most clients need a few of these, not all.<\/p>\n Employment income<\/strong><\/p>\n Self-employment and gig income<\/strong><\/p>\n Investment and retirement income<\/strong><\/p>\n Other income<\/strong><\/p>\n Ask for these as a separate sub-checklist. Business clients skip the personal deduction section, so keep it clean.<\/p>\n Ask an open question at the top of the intake: “Did any of these happen in the tax year?”<\/em> Then list the events that change the return.<\/p>\n Life events are where preparers lose the most money in missed opportunities. A client who quietly refinanced won’t mention it unless you ask.<\/p>\n Emailing a Word doc and asking clients to reply-attach files is where the process usually falls apart. Documents arrive in seven separate emails, some as photos, some named “scan1.pdf”, and you have no way to see what’s still missing at a glance.<\/p>\n A dedicated portal fixes that. Instead of chasing files by email, you send a link and every client uploads into the same structured checklist. You see completion percentages per client, get notified when uploads land, and can reject a blurry ID photo with one click.<\/p>\n Superdocu was built for this: collect client documents<\/a> through a branded portal, group requests by section (personal \/ income \/ deductions \/ business), set a deadline, and let the automatic reminders do the follow-up. For firms handling dozens of returns at once, that shift alone recovers hours per week during peak season.<\/p>\n A few practical tips that make a bigger difference than most software features:<\/p>\n For a broader look at how to build the request itself, see our document collection best practices<\/a> guide.<\/p>\n Requesting everything up front.<\/strong> Ask what applies. A retiree with a single 1099-R doesn’t need to see a Schedule C section.<\/p>\n Accepting photos of documents.<\/strong> A phone photo of a W-2 taken on a kitchen table is almost always missing an edge or unreadable in one corner. Ask for scans, or at least require the client to confirm all four corners are visible.<\/p>\n Not verifying the SSN against the ID.<\/strong> Rejected returns because of transposed digits burn hours during the busiest month of the year. Cross-check at intake.<\/p>\n Skipping the engagement letter.<\/strong> Even for returning clients, a signed engagement letter each year is your protection against scope creep and fee disputes. See our document approval workflow<\/a> guide for how to build sign-off into the intake step.<\/p>\n Leaving prior-year carryovers to memory.<\/strong> If you didn’t file the return last year, treat carryovers as their own document request. Ask for the prior return, then pull them out yourself.<\/p>\n At a minimum: government photo ID, Social Security cards for everyone on the return, last year’s tax return, all W-2s and 1099s you received, mortgage and property tax statements if you own a home, and receipts for any deductions or credits you plan to claim. Your preparer will send a checklist tailored to your situation.<\/p>\n The IRS recommends keeping tax records for at least three years from the filing date, and seven years if you claimed a loss from worthless securities or a bad debt deduction. Keep records of home purchases and business assets for as long as you own the property, plus three years after you dispose of it.<\/p>\n You can, but you shouldn’t. Email is not encrypted end-to-end and tax documents contain everything an identity thief needs. Use a secure client portal instead. Most modern tax preparers provide one at no extra cost.<\/p>\n 1099-NEC reports non-employee compensation \u2014 money paid to independent contractors, freelancers and consultants. 1099-MISC covers other types of payments: rents, royalties, prizes, awards and legal settlements. Before 2020 both types of income were reported on the 1099-MISC.<\/p>\n Yes. If you bought, sold, received or spent cryptocurrency during the year, bring the transaction history from every exchange or wallet you used. Every taxpayer answers a digital asset question on Form 1040, and unreported crypto activity is one of the IRS’s stated enforcement priorities.<\/p>\n The best tax preparer document checklist is one your clients actually complete. That means grouping requests by situation, hiding what doesn’t apply, sending scheduled reminders and giving people a place to upload that isn’t their email drafts folder.<\/p>\n If you’re still doing this over email, one tax season with a branded document portal will pay for itself in recovered hours.
